Field of technology

The technical solution relates to an electrically heated flat heating fabric for sleeping bags, sleeping pads, footmuffs, bags for the lower limbs, possibly also for electrically heated sleeping bags, electrically heated sleeping pads, electrically heated footmuffs, electrically heated bags for the lower limbs, namely in the low voltage range. The electrically heated flat heating fabric according to the technical solution is particularly suitable for use in the sleeping cabins of trucks.

Prior art

Heated sleeping bags are already known. Thus, DE 69327584 T2 describes an electric heater which is also suitable for sleeping bags. Here, an electrically conductive polymeric material is used in various layers, being partially connected to the electrode material, and this electrode material connects the polymeric material to an electrical energy source, and a thin-film battery is used here. At least one layer of the resistance heating unit is directly connected to the supply battery, or the energy source is integrated in the textile material.

DE 29901129 U1 describes a heated and air-conditioned sleeping bag which comprises channels inside the sleeping bag which serve for the flow of heating medium. Air or water is counted here as the heating medium.

The solution of the infant attachment device described in DE 201014157 U1 is also similar. Here it has a bulge that surrounds the infant. Here, fluid is also used as the heating medium.

The task of the technical solution is to create an electrically heated surface heating textile insert using a heating fabric for sleeping bags, sleeping pads, leggings and bags for the lower limbs in the low voltage range for the recreational area and especially for use in truck sleeping cabins. textile inserts have different heating properties compared to other areas of heating textile inserts.

The essence of the technical solution

The proposed technical solution allows the use of a flat heating fabric in the low voltage range, which, in addition to general heating, contains areas where additional heating power is allowed, or contains areas with heating power and also areas with no heating power. These areas of the flat heating fabric with additional heating power relate in particular to the area of the legs and the thighs, the pelvis up to the area of the kidneys and possibly also the area of the shoulders. If the sleeping bag according to the technical solution is to be used in particular in the sleeping cabins of trucks, the shape of the sleeping bag with a regularly running width is proposed. Areas of different heating power of the sleeping bag can be in the foot areas or also in the bags for the lower limbs, which can be pulled up to the pelvic area or to the kidney area.

The flat heating fabric for the sleeping bag and the sleeping pad is incorporated over the overall width of the product. In the case of a sleeping bag, the flat heating fabric does not have to be incorporated over the overall width of the sleeping bag in the lower and upper areas of the sleeping bag. Here, it is sufficient that the surface of the lounger and the area on the sides of the body and possibly in the area of the blanket be provided with a heating fabric. In the shape of the preferred embodiment of the sleeping bag, each zone of different heating properties is applied via

- 1 CZ 32670 UI total width of the sleeping bag. The flat heating fabric is placed between the textile lower layer and the textile upper layer of said products or is placed directly in the lower layer of said products and / or in the upper layer of said products.

By using electrodes which are electrically well-conducting textile strips and are guided over the total area of the flat heating fabric, different heating stages and heating areas can be set by means of suitable leads and supply options. The contacts on the lead electrodes are woven surfaces of metal fabric or pressed metal foil that, when used in a sleeping bag or sleeping pad, do not present any hard spots and do not damage the touch of a soft fabric. When using metal foils, these can be made single or double, twice on top of each other with the electrode lying in the middle.

The advantage of a sleeping bag or sleeping pad according to the technical solution for use in truck sleeping cabins is in particular that the car engine does not have to run throughout sleep to use its waste heat to heat or heat the sleeping bag or sleeping pad. Existing batteries used in vehicles are large enough to allow the sleeping pad or sleeping bag to be heated for hours in the low voltage range of rechargeable batteries. When using a textile insert as a flat heating fabric, there is an advantage and the possibility of even easier cleaning by means of a washing process. This is guaranteed by the polymeric heating fabric used, in particular the polymeric carbon fabric or the silver-coated polymeric fabric connected by the supply conductors to the supply battery or batteries.

By using and arranging the already known protection by means of the control device of the supply battery with corresponding plug-in contacts between the supply battery and the heating surface, the car battery is protected against deep discharge by timely switching off the heating. These supply battery control devices can be set with a cut-off voltage from 10.4 V to 13.3 V and a maximum consumption of 20 A. Between the supply battery and the supply wires to the sleeping bag or to the sleeping pad, there is a controller for the possibility of regulating the heating power . Heating power control is particularly advantageous for zones with different thermal properties.

Explanation of drawings

The drawings show several examples of the implementation of the technical solution and are described in more detail below. Giant. 1 is a cross-sectional view of a sleeping bag or sleeping pad with surfaces with additional heating power, and FIG. 2 is a top view of a heating fabric surface in an electrode arrangement to form bands with different heating properties.

Examples of technical solution

The electrically heated flat heating fabric 1 for sleeping bags or for sleeping pads, leggings and bags for the lower limbs is operated in the low voltage range and is preferably intended for use in the sleeping cabins of trucks. The sleeping bag and the sleeping pad preferably consist of a textile lower layer 9 and a textile upper layer 10. A flat heating fabric 11 is integrated between them or completely into the textile layer. The flat heating fabric 1 consists in particular of an electrically conductive fabric made of a polymeric carbon fabric or a silver-coated polymeric fabric. By arranging the additional surfaces 3 of the flat heating fabric 1, surfaces 2 with an additional heating power are created. These additional flat pieces of flat heating fabric 1 comprise separate supply conductors 7 from the supply battery 6. These additional flat pieces of flat heating fabric 1 are preferably arranged in the leg region and in the region between the thighs up to the kidney region. sleeping bag or sleeping mat. For example, the following arrangement of additional surfaces 3 of the surface heating fabric 1 is possible: From the lower end of the sleeping bag up to 10 cm without the surface heating fabric 1, an area of 30 cm follows as the leg area with additional areas 3 of the surface heating fabric 1 without area

-2GB 32670 UI of heating fabric 1, followed by an area of 40 cm with a flat heating fabric (hip area), then again an area without a flat heating fabric 1 with a size of 20 cm. The sleeping bag is followed by surfaces 2 with additional surface heating power by means of additional surfaces 3 of the surface heating fabric 1 (shoulder area) and the final upper area of the sleeping bag in the length of 30 cm without heating (Fig. 1). With this arrangement of the individual sizes of the additional heating surfaces for the sleeping bag mentioned here, a maximum output of 60 W can be taken from the 12 V battery supply network with a consumption of 5 A.

The same effect of creating zones 5 of different heating properties when using the flat heating fabric 1 can be achieved by using different kinds of flat heating fabric 1 with different heating power or by arranging the heating electrodes 4 in the flat heating fabric L. The electrodes 4 are electrically conductive textile tapes. The electrodes 4 are incorporated in the flat heating fabric 1 and extend in the longitudinal and / or transverse direction of the flat heating fabric 1 from one side thereof to the other at different distances. The greater the distance between the electrodes 4, the less the heating of the flat heating fabric 1. The electrodes 4 have an electrical contact 8 at one end and are connected to the supply conductors 7 of the supply battery 6.

The metal electrical contacts 8 are simultaneously woven into the surface heating fabric 1 on the surfaces of the surface heating fabric 1 or arranged on a metal foil in a single or double design. When using metal foils, these can be made single or double, double on top of each other with an inserted electrode 4. This does not create hard spots on the product and does not damage the soft touch of the fabric.

It is to be understood according to FIG. 2 of the drawing that the electrical contacts 8 are connected on one side of the surface heating fabric 1 to its other side in order to allow the required current flow through the surface heating fabric 1. Regulating or controlling elements can be provided in the supply conductor 7. , such as to set the desired final temperature. The consumption of electrical energy taken from the supply battery 6 is manually adjustable or selectable by means of a control mechanism, in particular for zones 5 with different thermal properties of a sleeping bag or sleeping pad.

Thus, for example, it can be additionally calculated for the supply supply conductor 7 for the sleeping bag, or for an electric blanket with the placement of the control device 11 between the supply battery 6 or, for example, a cigarette lighter socket and a sleeping bag, or electric sleeping pad.

The control device 11 prevents the discharge battery 6 from being deeply discharged.

In order to minimize the consumption of the power of the supply battery 6, a smaller amount of surface heating fabric 1 can be incorporated in the upper part of the sleeping bag.
