Do-it-yourself seat heating: let's look at a clear example. Seat heating test Seat heating elements

Car owners spend a huge amount of time behind the wheel of their car, so comfort plays an important role. During frosts, sitting on a cold seat is not the best thing to do, since the standard car heating is not always enough to fully warm up, especially when you need to get into a frozen cabin early in the morning. Heated seats are an excellent solution to this problem.

There are two types of such heating systems: external or external (covers and capes) and built-in (mounted under the upholstery of seats). To figure out which seat heating is better, it’s worth considering the features of these varieties in more detail.

External seat heating

This is the cheapest option, which is most often used by drivers if the car manufacturer has not taken care of heated seats for the car. Covers and capes are equipped with heating elements:

• carbon fiber wiring;
• nichrome spirals covered with a polyvinyl chloride sheath;
• Teflon coated wires;
• Fiber Thermetics thermal fiber.

The power of heating elements of this type ranges from 40 to 100 W with a current consumption of 4-8 Amps. External heaters operate from the cigarette lighter. Some models are equipped with touch or mechanical control panels. The method of fastening the product depends on the type of heater.

Types of external heaters

This type of system is divided into two categories.

"Capes"

Heated front seats of the overhead type are considered the simplest and most affordable. The products are made of rubberized or dense fabric, on which heating elements are attached. Such heating pads can be fixed using special Velcro or elastic bands with hooks. To install a heated seat cover, simply attach the lower hooks to the chair springs yourself. After that, just connect the “cape” to the cigarette lighter.

However, such simple heater options have many disadvantages:

• Most models do not have temperature controls, which often leads to overheating.
• The product is secured only with a few hooks or Velcro. Because of this, the cape constantly slips.
• "Capes" don't look very nice.
• The cigarette lighter is constantly busy.
• The rear seats cannot be heated.

Cases

Products of this type can be made from a variety of materials (fabric, natural or artificial leather, eco-leather). They are installed on top of the standard “seats” and connected directly to the on-board system, which is much better than heating the car seats from the cigarette lighter. At the same time, the products can be installed on all seats at once, without thereby disturbing the interior design.

Cases, as a rule, are equipped with additional control panels that allow you to control the heating temperature, thanks to which the risk of overheating is virtually eliminated.

However, if we compare heated covers for the front seats of a car and covers, the first type is much easier to install yourself. It's not that easy to put the cover on the seat. In addition, such systems require the installation of control buttons that are embedded in the car panels. It is recommended that this work be entrusted only to auto electricians.

In addition, the cost of covers is much higher. However, it all depends on the chosen model.

The best external seat heating systems

Most often, car owners choose the following products:

There are also special covers that are used for child seats. Among them it is worth highlighting:

In addition to capes and covers, there are also stationary heating systems, which are considered more reliable and durable.

Built-in heating

These elements are installed between the upholstery and the foam layer of car seats. They are made from special mats using nichrome spirals, carbon fiber and thermal fiber. Based on this, there are several features of the built-in heating system:

• Products with nichrome spirals are cheaper, but such elements cannot be built into every chair design. If the system intersects with reinforcement elements, it will have to be adjusted to the required size.
• Carbon fiber and thermal fiber mats can be installed on any chair without any restrictions. If necessary, they can be easily cut and given any shape. However, such models are expensive.

If we talk about the advantages of such systems compared to covers and capes, it is worth highlighting:

• Access to car cigarette lighter. The heating is connected to a separate power supply.
• Hidden connection of the system. There will be no wires dangling under your feet.
• Possibility of installing the heating system both on the rear seats of the car and on the front ones.
• High reliability of the system.
• The presence of a thermostat. Thanks to this, the device will not short-circuit.
• Possibility of installing the power supply in any convenient place.

Among the disadvantages of such systems, one can only highlight the rather high cost of the products. However, you can also find relatively cheap models.

The best built-in systems

To choose high-quality seat heating, you should pay attention to the following brands:

There are no permanent systems for child seats, since such installation of heated seats will be fraught with many difficulties. However, if necessary, you can make a heater for any type of seat yourself.

Do-it-yourself seat heating

In order to make such a system, it is enough to purchase a heating cable. If you want to save even more, then before making heated seats yourself, you can prepare ordinary nichrome wire with a diameter of 0.5 mm. It will act as a heater. After this, all that remains is to sew it onto thick fabric and attach it under the chair. The operation scheme is extremely simple. In order to make a homemade burn you need:

• Divide 3 meters of nichrome into two equal parts (one of them will go to the “seat”, and the second will be needed for the back of the seat).
• Sew it on the fabric with a zigzag (you can use old jeans).
• Connect the completed structure to a 12 V power source.

How to check that everything is working? Very simple. To do this, you need to wait until the wiring starts to heat up. If the seat becomes warm after a few minutes, then everything is fine. If this does not happen and the wire continues to heat up, it is recommended to connect a thermostat or other device to measure resistance.

You need to be careful and avoid overheating. Otherwise, a fire may occur. That is why it is not recommended for those who are far from electricians to independently manufacture such elements.

You can also make the heating a little differently, using the same nichrome wire. Only in this case it will be needed a little more - 10 m. From nichrome you need to form 4 spirals at a distance of 40 mm from each other, curling the wire in “figure eights”. For convenience, it is better to wind spirals on nails driven into the board.

After this, the spirals are connected in parallel and attached to a dense mother (again, you can use jeans). At the next stage, all that remains is to mount the relay and connect the system to the power source.

In custody

Before you install heated seats, you should check that it works. Even if we are talking about a ready-made heating system, it is worth connecting it and seeing how intensely the heating occurs before directly installing it on the car seats.

What kind of service is this?

The built-in installation of a heated seat kit is practically a factory option for heated seats. It will not dangle around the seat, as is the case with a cape, and “get off” it. The set will not be felt through the seat upholstery, will not be visible at all, and will work reliably. The heating system will not be plugged into the cigarette lighter like a heated seat cover. And the heating of the car seats will be carried out with protection, and you will ultimately get a very comfortable and useful function in the cold season, worthy of having a place in every modern car.

We use proven heating kits and provide a 1 year warranty on the system. It should be noted that installation of heated seats is made using a standard installation kit, which includes a heating element made of carbon material placed between two layers of woven material. It has a high degree of strength as well as good flexibility. The delivery set also includes an electronics unit that provides automatic locking in the event of a system short circuit. The system is monitored and controlled in four-channel mode using convenient control buttons.

The car owner himself chooses the desired mode, especially since it is possible installation of heated rear seats separate from the heated driver's seat. The installation kit comes with the appropriate mounting hardware, a protection relay and a whole bundle of wires, which only experienced electricians can handle. By ordering the service of a mobile electrician, you can avoid additional costs of time and money for dismantling and re-installation if the installation is not carried out correctly. This service is cheap, and a mobile electrician will save the car owner up to 30% compared to a dealer network of services.

Keep in mind

Installation of heated seats adds comfort to everyone in the car dealership. Warmth is especially beneficial for the female body, but men should not turn on the heating constantly. Of course, heat is therapeutic for osteochondrosis and radiculitis, but it is undesirable for the reproductive sphere of the male body.

Covers made of fabric materials, as well as velor or leatherette, warm up the best. Leather upholstery is more demanding and has a higher heat loss coefficient. It requires a more powerful heating element, which an electrician will select individually.

How important is it

Before installing the kit, be sure to evenly distribute the heating element and secure it properly to avoid displacement during operation. This is especially important for overweight drivers. The electrician should also check the system for a safety sensor that can automatically shut down the system in the event of a danger. High quality installation of heated seats price The issue is minimal, and the benefits are obvious to everyone.

Winters in our country can be very frosty. It can be very cold in the car. Even turning on the stove doesn't help. For this reason, expensive car brands are available with heated seats. Budget models do not have this function. However, owners of such vehicles can install the system themselves.

Most often, heating is provided only in the front seats. For passengers behind the driver, riding in a car in cold weather can be uncomfortable. Therefore, there are many systems that can be used to heated rear seats. They are easy to install yourself.

Varieties

Passenger car, jeep or crossover with heated rear seats can be found quite often today. At the same time, owners of such vehicles can choose different options for electrical systems. Heating wires run inside such products.

The market for special products for cars includes covers, heated covers, as well as built-in systems. The first two types of products are characterized by low cost and ease of installation. However, these varieties are not without certain disadvantages.

Many drivers prefer to install embedded systems. Their installation is more complicated. However, almost everyone can do it on their own. In auto repair shops, such a procedure will be quite expensive. Despite the complexity of installing heating wires under the surface of the seat covering, this option is one of the most preferable.

Selecting the heating type

Overhead covers and heated capes are quite inexpensive. You can purchase similar products at a price of 500 rubles. However, you should immediately understand several nuances associated with their operation.

First of all, experts say that the quality of such capes is mainly inferior to built-in wires. However, the heating of this product may not meet established standards. Some manufacturers create seat covers that heat up to 40ºC. This negatively affects the reproductive function of a man.

Using overhead covers has another drawback. Such products are connected to the network via the cigarette lighter. As you know, he is the only one in the car. Therefore, such a product assumes that the cover can only be used for the driver’s seat. In this case, heating the rear seats will not be possible. When using a splitter, you can expect the fuse to fail. Too much current will pass through it. Therefore, built-in systems for rear seats are preferable.

Price

All built-in systems for heating rear seats on sale can be divided into three categories. The most expensive products are those made in Germany. The most famous system in this category is Weaco. A set of built-in heating for 2 seats costs about 16 thousand rubles.

Domestic products were included in the mid-price category. Systems are in greatest demand heated seats "Emelya",“Teplodom”, “Avtotherm”, etc. Such sets can be purchased at a price of about 4 thousand rubles for 2 seats.

The cheapest products are made in China. Similar products can be purchased at a price of up to 3 thousand rubles. for 2 seats. There are products whose cost does not exceed 1.5 thousand rubles. per set. The quality of the products presented varies significantly. To choose a worthy option, you need to consider expert reviews.

How to choose a seat heating system?

There are many built-in heating systems on the market. They differ in quality and cost. The most expensive and high-quality electrical systems are made in Germany. These are universal products that can be used to warm the seats of almost any brand of car. The degree of protection of electrical wires here is very high. Failure within the specified service life is unlikely.

Domestic manufacturers present many varieties of such systems on the specialty product market. The greatest demand among buyers is heated seats "Emelya".

Experts say that Russian-made products are not inferior in quality to German products. But the cost of domestic systems will be an order of magnitude lower.

Chinese seat heating products are the least expensive. They have a low protection class. Wires are easily damaged. They may fail in the first year of operation. This may result in overheating of the system and even a fire. It is not recommended to purchase such systems.

Preparation for installation

When choosing the best embedded system option, you need to carefully study instructions for heated rear seats, which comes with the product. The manufacturer specifies a number of mandatory requirements that the installer must fulfill.

Next, you need to inspect your car. Many modern vehicle models do not have a built-in heating system. However, manufacturers assume that the owner will want to install such a product himself. Therefore, the car may have all the necessary terminals and wires for connection. This will make installation much easier.

Next, you need to determine the amount of materials needed to install the heating. You need to prepare wire, tape, electrical tape, a knife, screwdrivers and scissors. It is also recommended to take pliers and glue. After this, you can begin the installation.

Selecting the location of the button

With help rear seat heating buttons You can turn the system power on and off. The button can be installed in a place convenient for users.

Most often, such a control element is installed on the armrest of the rear seats. It is very comfortable. However, some car models do not have rear seat armrests. Therefore, the car owner can purchase them himself. Products are available for sale in which holes have already been made for installing a heating system button. In a regular armrest you will have to make the seat yourself.

In some cases, it is more convenient for the driver to place the button on the dashboard. In this case, it will be convenient for him to independently control the system, turning it on and off if necessary.

Wiring

Involves installation of wiring. The location of communications must be carefully considered. They should not interfere with passengers and the driver. Also, a large number of unsightly wires can spoil the appearance of the interior.

Communications must be laid so that they can be hidden under various structural elements. If they get tangled under your feet, the wire can easily be torn. This is unsafe. Not only will the system stop working and require timely repairs, but there is also a chance of getting an electric shock.

A large number of wires in the cabin can interfere with the driver's ability to control the vehicle. Therefore, all communications should be as hidden as possible.

Connecting wiring to the network

Built-in heated rear seats requires proper connection. Before starting this procedure, you must re-read the manufacturer's instructions. It clearly indicates how to properly connect the wires to the network.

Many drivers make the grave mistake of connecting the system to the cigarette lighter. In this case, it will be impossible to operate the heated seats. The fuse is not designed for such a load. Therefore, it will quickly fail.

It is best to connect the wires directly to the vehicle battery. In this case, it is necessary to correctly calculate the total load that will be determined in the system during the winter period. In some cases, you will have to sacrifice some other systems (for example, music) in favor of heating.

Dismantling procedure

To mount heated rear seats, the rear seats will need to be removed. This is a rather labor-intensive process. Those who have never performed such an operation before may experience certain difficulties. It is this stage of heating installation that usually takes a lot of time.

When the rear seats are removed from the interior, you will need to carefully remove the upholstery from them. This must be done very carefully. Otherwise, the material may be damaged. In this case, you will need to buy new chair covers.

After this, you can begin installing the system. Experts advise choosing types of heating that do not turn on if no one is sitting on the chair. This allows you to operate the vehicle's electrical system more efficiently.

Installation

After all the preparatory work has been completed, you can begin installation of heated rear seats. The wires will be located on the back and on the seat. The manufacturer most often includes glue or tape in the delivery package. With their help you can fix the system on the surface. Some heating products contain an adhesive base. In this case, installation is even easier.

Installation of wires is carried out in a warm room. If you neglect this recommendation, you can expect that the glue will not be able to provide the required adhesion of the mat to the base.

After the heating elements are securely fixed to the surface, it is necessary to put the upholstery on the seats. After this, the seats are again installed in the car interior. You need to check the functionality of the system. When all the wires are connected, you need to turn on the heating. Experts recommend including fuses in the network. This increases the operating safety of the system.

Features of operation

most often can be adjusted. For this purpose, the system has a thermostat. It turns off the electricity supply when the seat reaches the set temperature. Also, some products provide for heating only the back or only the seat. The manufacturer may also provide a function for testing the condition of the wires. If they break, the sensor signals the driver about a malfunction.

Having considered the features heated rear seats, You can install such a system yourself.

Manufacturers usually install a heating system for front seats on top-spec cars. The basic versions do not provide such a function, although in temperate climates it is quite in demand. The owner of a budget car has no choice but to make heated seats with his own hands.

Advanced car enthusiasts practice 3 popular options:

• buy and put on a ready-made heater in the form of a cape or cover;
• purchase an installation kit mounted inside the standard pillows;
• Make your own heating elements from scratch and install them on your car.

Using heating blankets

The simplest way to quickly organize heating of the front seats is to buy a special cover with built-in elements. The product is sewn from thick fabric and equipped with elastic stretchers with metal hooks at the ends. The latter are needed to attach the pad to the seat.

The advantages of the car accessory are obvious - ease of installation and connection (the heating circuit operates from the cigarette lighter socket), the possibility of quick installation using stretchers hooked onto springs. But capes have much more disadvantages:

• frankly unpresentable appearance;
• to charge your phone or connect another gadget to power, the heater plug will have to be removed from the cigarette lighter socket;
• only one of the two chairs is heated;
• heated rear seats are not available.

Overlays also have less significant disadvantages that cause inconvenience. The accessory, held in place by elastic bands, fidgets across the chair cushion and constantly works at full capacity. Instances with temperature control have a higher price and often fail.

The option with car covers, where heating elements are sewn, is more convenient and reliable, but expensive. The material of the products is genuine leather, various fabrics and so-called eco-leather. The covers are designed for heating the front and rear seats, are equipped with thermostats and are connected to the on-board network separately from the cigarette lighter.

In addition to considerable cost, heaters in the form of covers have a second drawback - the complexity of installation. It is better to entrust the tensioning of products and electrical connection to specialists from a specialized car service center.

Installation of factory elements

For almost any car you can purchase a heating installation kit, which includes the following parts:

• heating elements for seats and backrests;
• connecting wires with connectors;
• power buttons;
• Temperature regulator.

There are 2 types of kits: original, designed for a specific car model, and universal. The latter are selected according to the size of the pillows.

To install such seat heating yourself, it is recommended to completely remove the seats from the car. Then follow these instructions:

1. For convenience, disassemble the sofa into 2 parts, separating the back.
2. Carefully remove the outer trim (the method of fastening depends on the make of the car).
3. Place the heating elements on top of the foam inserts and secure by gluing or in another way provided for in the kit instructions.
4. Stretch and secure the upholstery, assemble the chair and place it back into the cabin. Lead the wires down and lay them under the floor covering to the point where the buttons are mounted.
5. Insert the button blocks into the free space of the center console. Connect the heaters to the on-board network by installing an additional fuse.

It’s easier to install the original set of products yourself - the buttons are made to fit standard sockets with plugs, and the heating inserts fit perfectly to the size of the seats. You will have to tinker with the parts of the universal set - the button blocks need to be embedded into the plastic panel, choosing a convenient place. The protruding edges of the heaters are tucked under the side support elements.

Note. In some cars, it is not necessary to remove the upholstery of the sofas. The design allows you to insert the heater under the cladding from the rear side.

The many advantages of such kits are overshadowed by one drawback - the not very affordable price of quality products. Cheap Chinese copies that fit the sofas of various cars quickly fail, as evidenced by numerous reviews from car enthusiasts.

Materials for self-production of heaters

The cheapest way to get heated car seats is to make it yourself. For production you will need the following materials:

• heating wire;
• heat shrink insulating tube;
• thick fabric;
• connecting wires;
• fuse block, buttons or plug for the cigarette lighter socket.

The main question is which wire to use to make the heater. The simplest option is to buy a ready-made heating cable, but such a solution is associated with financial costs. It is cheaper to make the element yourself using the following materials:

• thin high-resistance wire made of chromium-nickel alloy (in common parlance - nichrome);
• LAN wires – a cable used to connect to the Internet (the second name is twisted pair);
• thin copper wires from any other cables.

The length of the conductor for homemade heating is determined by the resistance of the section. Based on the power of each built-in element of 40 W, we obtain the required resistance of about 4 Ohms at a supply voltage of 12 volts. Connect the first clamp of the multimeter to the end of the wire, and use the second to determine the length of the heating circuit: move the contact until the display shows a value of 4 ohms.

Advice. If the conductor is covered with insulation, calculate the resistivity per 1 m length by measuring the entire section and dividing the reading by the meter. Then tap off the required amount of cable with a tape measure.

If you need to splice pieces of wire together to create the required resistance, connect the ends of the copper strands by soldering. Nichrome wire will have to be selected in one piece, since it can only be connected by welding.

Instructions for installing homemade heating

To install the heating elements yourself, it is better to remove the seats from the car and remove the trim in advance. Also disassemble part of the center console to install buttons and connect wires. Assembly is carried out in this order:

1. Take a thick fabric and cut it to the size of the seat cushions.
2. Lay the previously measured piece of wire in the form of a snake or in zigzags on top of the fabric. For uniform bending, screw the conductor onto 2 nails driven into the board.
3. Cover the improvised heater with a second piece of cloth and connect it to a 12 V power source for testing purposes. If the element is too cold, shorten the length of the circuit; if it is very hot, lengthen it.
4. Sew the heating wire to the top and bottom fabric, bringing the ends out. Solder the connecting wires to them and insulate them with heat shrink tubing.
5. Place the heaters under the trim, assemble the chairs and set them in place.

Connecting heated seats from the cigarette lighter is the simplest solution, since this electrical circuit is already protected by a fuse. To avoid occupying the socket with a plug, bring the wires from the inside and attach them to the contacts. Place the buttons and thermostat in any free space on the console, lay the wiring under the carpet.

Homemade heaters are certainly cheap. But how they will perform over many years of operation is unknown. Therefore, the best option is to use high-quality factory products, although this entails financial costs.

(function(w, d, n, s, t) ( w[n] = w[n] || ; w[n].push(function() ( Ya.Context.AdvManager.render(( blockId: "R-A -227463-10", renderTo: "yandex_rtb_R-A-227463-10", async: true )); )); t = d.getElementsByTagName("script"); s = d.createElement("script"); s .type = "text/javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; , this.document, "yandexContextAsyncCallbacks");

Not every modern car is equipped with heated seats; such equipment is often available only in top trim levels. And even though controversy surrounding the usefulness of the option does not subside, most drivers still prefer this comfortable function and install the heating kit themselves.

What kind of seat heating you can install yourself: types of heating elements

The car accessories market today is able to satisfy almost any requirements of motorists. This fully applies to products intended for heating seats, which are available in two types:

1. Covers and capes.
2. Built-in.

Cases and capes

Before you make heated seats yourself, you need to know that the first option is characterized by its low price and ease of installation. All you have to do is put the cover on the chair, connect it, and the kit is ready to go. Typically the heater is plugged into the cigarette lighter socket, but terminal connections are also possible. However, this type of heating organization also has a number of significant disadvantages:

• low electrical and fire safety;
• uneven heating of the area;
• discomfort from wires;
• violation of the interior layout;
• impossibility of using covers on the rear seats.

There is one more problem. Many drivers plug in other gadgets into the cigarette lighter socket, for example, a GPS navigator, a video recorder, or a phone charger. Using a splitter is not a solution to this situation - the heating element consumes a significant amount of energy and the fuses may fail. In addition, there is a threat to the fire safety of the car.

Built-in models

Car owners who decide to organize seat heating with their own hands are confused by this option because of the installation difficulties. Here they can be reassured - detailed recommendations from experienced car enthusiasts will help everyone who knows how to hold a screwdriver in their hands to complete the installation. It is enough to carefully study the proposed technology and have a nominal set of tools. In addition, the advantages of embedded systems compared to capes are obvious:

• the possibility of equipping not only the front seats with heating, but also the rear ones;
• hidden connection, wiring is laid under the interior trim;
• direct connection to the on-board network, the cigarette lighter socket is accessible to other consumers;
• The profile of the chair and the interior components of the cabin do not change.

Since everything is clear with heating covers and capes and their installation raises absolutely no questions for anyone, below we will talk about built-in systems.

Briefly about the choice of heating elements

The range of elements that are mounted directly into the body of the chair is quite extensive. This allows you to do optimal choice based on the design features of the interior and its components, as well as the financial capabilities of the owner. The most popular products are from Russia, China, Taiwan and Germany. Here are some examples of models:

• installation kits from the company Weaco (Germany);
• built-in blocks "Emelya" from the company "Teplodom" (Russia);
• kits "IN" from the Avtoterm group (Russia);
• sets from Megalight (Taiwan);
• kits from Autoline International (China).

Naturally, all models differ both in terms of workmanship and price. Owners who already know how to properly heat seats with their own hands assure that the high cost of German equipment is compensated by its reliability and versatility. Its elements are equipped with overheating protection and have several operating modes.

Russian models of heating technology are practically not inferior to German ones; reinforced cable or carbon fiber is used as a heating element. The kit includes an electronic temperature controller and overheat protection.

Products from China are attractive in price, but most often this is where all the advantages end. As our car enthusiasts note, the main problems with such kits are:

• broken power button;
• short circuit or broken wiring;
• uneven heating of the chair plane.

Practice: how to make stationary heated seats with your own hands?

So, the choice has been made and the heating kit has been purchased. All that remains is to prepare the necessary materials and tools. These include:

• a set of screwdrivers and wrenches for disassembling the chair;
• electrical tape and heat shrink tubing;
• plastic clamps;
• multimeter;
• scissors and a knife with replaceable blades;
• pliers;
• soldering iron;
• marker;
• glue 88 or double-sided tape (available in the installation kit).

To all this, we can add that the set of materials may vary depending on the configuration of the product. For example, if there are no wires or a fuse connector, then you need to purchase them. A stranded wire with a cross-section of 2.5 mm² is suitable for wiring.

Before you organize the heating of the front seats with your own hands, special attention should be paid to the placement of the control buttons that are included in the kit. It is important to study the method of their fastening and dimensions, since there is a possibility that the buttons will not fit into their normal place. Then you will have to choose another place or purchase control elements for a specific car. Further, all work is performed according to the following scheme:

• dismantle the seats and carefully remove them from the car;
• disassemble the seats, remove the headrest and all plastic elements; work better at a desk;
• remove the seat upholstery, which in most cases is fixed from below with metal rings or plates; You don’t have to completely remove it – just make room for heating mats;
• remove the trim from the back, to do this you need to remove the plastic bushings for the headrests;
• lay the heating fabric on the foam base and mark its contours with a marker;
• if there is a temperature sensor, fix it on the foam rubber;
• stick strips of double-sided tape along the marked lines or apply glue 88;
• fix the heating mats on the back and seat; in this case, be sure to pay attention to the position of the wires - for the driver's seat they should be on the right, and for the passenger seat - on the left;
• bring out the power wires;
• install the casing on a foam base; in places where necessary, use plastic clamps;
• reinstall all plastic elements and head restraints;
• install the seats in their standard places and lay the wiring to the locations of the controls and power connections.

Important! Motorists who already know how to make stationary heated seats with their own hands are recommended to pay attention to the laying of the wires that go from the regulators to the heating mats. Under no circumstances should they be stacked; it is necessary to leave a reserve in case the chairs need to be moved back.

Connecting heating elements

Every self-respecting manufacturer completes the installation kit with instructions for connecting the unit to the vehicle’s on-board network. If this stage causes certain difficulties or you are unsure of your abilities, then it is better to immediately contact electrical specialists.

(function(w, d, n, s, t) ( w[n] = w[n] || ; w[n].push(function() ( Ya.Context.AdvManager.render(( blockId: "R-A -227463-2", renderTo: "yandex_rtb_R-A-227463-2", async: true )); )); t = d.getElementsByTagName("script"); s = d.createElement("script"); s .type = "text/javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; , this.document, "yandexContextAsyncCallbacks");

For those who are confident in their own abilities, the following recommendations will be useful:

• using a multimeter, you should detect the 12 V power supply, backlight and ignition circuits;
• connect the positive wire of the thermal relay to the ignition switch connector, where power appears only after turning the key;
• connect the supply wire through a fuse to the positive terminal of the battery;
• connect the negative wire to ground;
• connect the button illumination wires to the cigarette lighter contacts;
• solder and insulate all connections;
• check the operation of the system.

For example, below is a diagram of the connections of the Emelya UK kit.

Important! With a correctly assembled circuit, the heating will function only when the ignition is on. Otherwise, forgetting to turn off the system, you risk starting the engine in the morning “with a pusher” or using , because the battery will be discharged.

How to make your own built-in heated rear seats in a car?

(function(w, d, n, s, t) ( w[n] = w[n] || ; w[n].push(function() ( Ya.Context.AdvManager.render(( blockId: "R-A -227463-4", renderTo: "yandex_rtb_R-A-227463-4", horizontalAlign: false, async: true )); )); t = d.getElementsByTagName("script"); s = d.createElement("script "); s.type = "text/javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; t.parentNode.insertBefore(s, t); ))(this, this.document, "yandexContextAsyncCallbacks");

This option is quite rare on budget class cars. For some motorists it is not of interest, but for those who have a large family, a warm rear sofa will not be superfluous. The technology for installing and connecting equipment is identical to that described above.

To implement built-in heated rear seats, you will need two heating kits. Despite the fact that the installation process is carried out by analogy with the front seats, it is worth briefly considering the main transitions:
