Foam pad factory

P. coreless upholstery with increased load capacity in Seat or back mirror.

The innovation relates to high upholstery without a spring core elastic foam for vehicle seats, upholstered furniture and back cushions.

It is often necessary to give a high cushion made of foam rubber or synthetic foam an increased [load-bearing capacity, without significantly increasing bulk density or effort.

Are known by the applicant or rubber coconut plates Molded parts, completely or five-sided foamed with latex or synthetic foam. The applicant has also made known thermally deformed synthetic foam covers through old property rights to be deposited with simple rubber hair plates.

It is also known to make rubber hair moldings with a soft Seat mirror made of latex or polyurethane foam to be seen in order to get a soft seat with a high load-bearing capacity. These Developments are not considered here.

The task here is to put through a spring core-less high padding made of foam rubber (latex foam) or synthetic foam to make suitable means more sustainable.

It has already been suggested that fabric inserts in the upper Foam half of the pad at right angles to the direction of load. Apart from the fact that the foam flow is thereby sensitive is disturbed, a relatively cumbersome manufacturing method is necessary.

It has also been proposed that grids made of high quality plastics embed, which is expensive.

Another stroke of the goal provides for a steel frame with a metal or wide-meshed textile fabric to be foamed in the upper area. Experience has shown that such insoles are unsuitable because the contact surface is much too small for the continued flexing stress. The wires wear down the foam after a short time and grind it into crumbly flour. ^ _

Based on these experiments, the applicant already proposed in her application dated February 1, 1961 (Az. 1 19 557 X / 34g) to enlarge the contact surface of (leather) wire by inserting the wires into suitable plastic films or hoses enveloped and then foamed. The foam combines excellently with the plastic film and gives the wire insert a substantial widening, even if wide passages for the foam remain between the individual wire inserts. It was not known that the foam was cut through or worn down, while the wire insert can move within the foil envelope to a limited extent _{5 in} accordance with the changing pressure load.

There, however, a spring insert is intended instead of a spring core to save foam material and to enlarge it the load-bearing capacity. But this effort should still be there can be saved.

According to the innovation, the easiest way to do this is to a plate (2) made of softer foam rubber or synthetic foam attached to the mold cover and the latex foam or the Pour artificial foam into the bottom of the mold. The foam then connects to the plate (2) and penetrates into it Edge zone collapses and forms a film (3) · This compacts the edge zone and the load-bearing capacity through the distribution of the area elevated. This method can be used particularly well with synthetic foam (Fig. I)

In the case of higher requirements, the inserted plate (2) can advantageously be concealed on its underside with a Grummihair-pressed pile (4) or a porous fabric layer or G-web strips lying on gaps, into which the foam penetrates, collapses and thus forms a very stable film (Fig. II)

If the intermediate plate (4) is only the size of the bottom of the insert plate (2.) and leaves the bevelled sides free, an almost imperceptible transition to the seat is formed, like is shown in Fig. III.

Often, however, the demand is made, especially the peripheral zone to stiffen to get a tight fit. In this case, it is recommended that the liner (4) be at least partially

to lead into the sloping sides and to end only a few millimeters below the seat surface (4a) .. This is easily possible, especially with pressed pile and G-web panels, as demonstrated in FIG.

This proposal also offers a manufacturing technology Range of gate parts:

1.) The insert plate (2) can be made of cheaper plate material any softness can be cut.

2.) It can be made of foam rubber.

3.) They can be made of soft. Be made of rubber hair.

4.) But you can also use the insert plate thermally Produce deformed sheet goods (8) (Pig. YIII), advantageously taking the heat from the Underside,

5.) The high upholstery (i) can be both with a recess (5) molded? / earthed, as well as from! block material molded be.

6.) The high upholstery (1) can be made with the recess (5)

Foam rubber is made, quite apart from the fact that it is also .—. can be made from the tried and tested rubber hair.

7.) The insert plate (2) can be foamed in without adhesive work, but it can also be glued in to create variants

to have.

8.) Finally, there is also the possibility of the inner part of the seat (7) made of rubber hair or connected To manufacture flakes with and without recesses (9) and cover them with a soft foam rubber or foam sheet (2) to cover and then to foam around this packing, as shown in Fig. VI and VII.

But it is just as possible to foam this filler body without a cover plate (2) in such a way that the homogeneous foam flows around the packing on five sides.

In any case, there is the possibility of integrating a fastener (6) so that it is either cuts with the outer edge of the floor or protrudes beyond the floor contours without being penetrated by the foam (6a).

The foam penetrates the fastening means at the edge zones (6b) and is thereby closely connected to the upholstery body. On the other hand, the overhangs (6 _a ) provide excellent fastening options. This fastening means (6) can advantageously consist of compressed rubber pile or a porous fabric.

In all cases, the increase in load-bearing capacity is due Achieves resources that do not require expensive lorms or hang-ups make necessary. The parts to be foamed are simply attached to or through the lid.
