Definitions

• the present invention relates to a heated cushion for a vehicle seat.
• the heated cushion according to the invention comprises an upper part and a lower part, as well as a heating coil.
• Heated seats and heated cushions for vehicle seats can be found in many different versions.
• the heat is most often generated by means of electricity which is conducted through one or more so-called heating wires disposed in the seat or the cushion.
• the heating wire is often arranged between two layers in the seat by means of a glue, by which the wire is fixed and the two parts are held together.
• the holding together of the two layers and the glue-fixing of the wire gives rise, however, to a number of drawbacks: the glues which are used often have an adhesiveness which varies with temperature, above all when the glue ages. This can make the parts come loose, even at relatively low temperatures.
• a heated cushion for a vehicle seat which comprises an upper part having a first and a second main surface, and a lower part having a first and a second main surface, in which the parts are arranged with their first main surfaces facing each other.
• a heating coil On one main surface of one part there is disposed a heating coil, and the upper and the lower part each have one half of a fastening system in Velcro material, the heating coil being secured in its main surface by the Velcro elements of the main surface.
• a heated seat is therefore obtained, whose components can be easily separated from one another for recycling purposes, and whose components additionally have a cohesion which is not dependent on temperature or age.
• the seat components obstruct air flow, which makes it possible to integrate the seat into a vehicle seat having a ventilation system.
• the upper or the lower part of the seat is realized in a fabric material, which further increases the air permeability and increases the possibility of integrating the Velcro material into the seat parts.
• Fig. 1 shows the components in a heated seat according to the invention
• Fig. 2 shows how the components from Fig. 1 are meant to be assembled.
• Fig. 1 illustrates the basic component parts in a heated seat 100 according to the invention.
• the seat 100 comprises an upper part 110 and a lower part 130, both of which preferably are substantially flat and have a first and a second main surface.
• the respective first main surfaces of the two parts 110, 130 are intended to be arranged one against the other in the resulting seat 100.
• a heating wire 120 which is connected to an external system (not shown in Fig. 1 or Fig. 2) in order to make the wire give off heat.
• the external system is usually an electrical system in the vehicle, which can comprise a control system for controlling the quantity of heat which is given off.
• the seat 100 according to the invention is equipped with an alternative system for holding together the seat and for fixing the heating coil 120; the upper part 110 and the lower part 130, on their respective first main surfaces, each have one half 115 and 135 respectively of a fastening system in Velcro material (more commonly referred to as "hook and loop").
• the Velcro elements 115 and 135 are shown in Fig. 1 as separate from the seat parts 110, 130, but are intended to be disposed on the first main surface of the respective seat part so that they will be facing one another.
• the Velcro elements 115, 135 can, of course, be fastened to their respective main surfaces in a variety of ways within the scope of the invention, but in a preferred embodiment at least one of the parts 110, 130 is made in a fabric material.
• both the parts 110, 130 are made in fabric, which makes it possible to integrate the Velcro elements 115, 135 into the fabric.
• the Velcro elements 115, 135 are used for fixing the heating wire 120 in the desired position in the seat 100.
• elements from both surfaces will combine to fix the wire 120, but in a manufacturing phase only Velcro elements belonging to one surface are initially used. This involves, in the manufacture or assembly of the seat 100, the heating wire 120 being pressed down against the Velcro surface 115, 135 so that the individual Velcro elements enclose the wire, and hold it on the main surface of the particular part 110, 130.
• the heating wire 120 is placed or pressed onto the Velcro surface, which is constituted by hooks or the like, the latter clasping and encompassing the wire until the second main surface is applied.
• FIG. 2 This is shown in Fig. 2, in which the wire 120 has been clamped in the Velcro element 135 of the lower part 130, whereafter the upper part 110 is applied to the lower part and the Velcro surfaces 115, 135 mutually engage.
• the Velcro elements from both surfaces will enclose the heating wire 120 and combine to fix it in the desired position in the seat 100.
• a heated seat for a vehicle seat has therefore been obtained, which is easy to take apart for recycling, which does not obstruct ventilation of a vehicle seat, since the principal elements can be made of fabric, and the securement of which is not dependent on temperature or age.
