Description

SK 5452 Υ1

Technical field

The technical solution relates to a heated assembly, in particular for seats and bench rests.

BACKGROUND OF THE INVENTION

In the case of simple bench-type seats, mainly made of wood, metal, stoneware or plastics, their seating and support parts are generally uncomfortable in shape and feel cool. In order to improve the seating quality, different pads, backrests and other accessories are made to improve the seating quality.

Among the known constructions are, in particular, a solution according to DE-A-060510. 3,334,744, wherein the seat assembly is a sheet metal layer molded between two plastic layers. Similarly, according to DE-A-0605105, the patent no. 1 635 508, a heating wire is placed between two plastic layers. The construction described in GB patent no. No. 1,319,168 is made to heat the walls, the heating wire being impregnated into a fabric that is covered with a plastic sheet.

The disadvantages of these solutions are in particular uneven temperature distribution and complicated assembly of the assembly.

From DE patent no. No. 2,607,949, a flat heating element is known in which the heating wire is woven into a fabric. The disadvantage of this solution is that it is dangerous from the point of view of electric current to the touch and the heating is not even.

The essence of the technical solution

The above-mentioned drawbacks are largely eliminated by a heated assembly, in particular for bench seats, consisting of a heating element and additional layers, according to the present invention, which consists in that the heating element consists of a graphite fabric which is placed in the upper and lower layer packaging. The thermal insulation layer is separated from the heating element by a layer of electroinsulating foil, the assembly being covered by a textile decorative layer.

The graphite fabric is provided on both sides with conductive strips with edge contacts for supplying electric current.

The earth conductor is connected to the thermal conductive layer.

The decorative layer is located on or on the surface and at least one edge of the assembly.

The heater and the additional layers are made of moldable materials.

The advantage of the assembly is better thermal distribution of the heating, easy assembly and good formability to body contours, which guarantees a higher sitting comfort.

BRIEF DESCRIPTION OF THE DRAWINGS

The solution is illustrated in more detail in the accompanying drawing, in which Figure 1 shows a cross-section of the assembly.

Example

The heated assembly (Fig. 1) for the seating part of the wooden bench 1 is assembled from a heating element 2 with a thickness of 1.2 mm, above which a 0.15 mm thick copper sheet is placed, which forms a heat-conducting layer

4. The copper sheet is electrically grounded (not indicated in the figure) and is insulated from the heater body 2 by a 0.25 mm thick Mylar polyester electrical insulating sheet 3. The copper sheet is covered with a carpet on top, which forms a decorative layer 5 and this front layer also covers the front face of the bench 1.

The heater 2 is made of graphite fabric 22, provided on both sides with electrically conductive strips 221 terminated with contact terminals (not indicated in the figure). The casing of this heater 2 is made of an upper and a lower layer of plastic insulation 21 mechanically joined at both lateral ends of the graphite fabric 22.

The assembly is assembled by first cutting longitudinal strips from the heating element strip 2 to measure the entire surface of the seat part of the bench 1. After cutting, by means of special pliers, the contact terminals for supplying electric current are pressed onto the ends of the conductive strips 221. conductors (not indicated in the figure). The contact terminals and ends of the electrically conductive strips 221 which have been exposed by cutting are insulated. The heater thus prepared is placed on the bench 1 and covered with an electro-insulating foil

SK 5452 Υ1 is placed on the copper sheet of the heat-conducting layer 4, which serves to distribute the temperature evenly over the whole surface of the bench 1, whereby its grounding conductor is connected to the ground, providing protection against contact with dangerous voltage. In the final assembly phase, carpet material is laid on the seat surface of the bench 1 and its edge as a decorative layer 5 for the grounded heat conducting material.

Industrial usability

The heated assembly according to this solution can be used mainly for seating parts of benches, but also for its support part and for virtually all kinds of seats, including automobile, or for heating various other spaces intended for this purpose, including floors and walls of interiors or exteriors buildings.

With floor heating, compared to conventional heating systems used up to now, e.g. with radiators, it can save a great deal of energy and can also reduce the air temperature by 2 - 3 ° C. At a lower temperature and higher relative humidity, the feeling of heat is better than with the above-mentioned radiator heating. The electric-powered floor heating can be easily regulated, which is an advantage of this heating assembly.

They are particularly suitable for heating benches in institutions where there is no heating. Such heating can be used e.g. in churches, theaters, metro stations, street stalls, etc.
