¹¹ Process for the production of re-entrant gaps on seat cushions or the like, and articles produced by means of the process »

Subject of the innovation is a method for forming re-entrant, d.iu- hollow Palten in coatings of cushions for seats, backrests, armrests, etc. of seats and similar elastic articles (convertible "furniture, Mattresses etc _0), and in particular, though not exclusively, for the manufacture of vehicle seats.

The innovation also relates to the means of the control system Process produced cushions, seats or the like.

The innovation aims in particular to meet the training so that the articles produced better than before the various Meet practical requirements.

Such gaps are created on the inside or on the back the covering of such a cushion along the palte to be formed is a flexible one, preferably made of textile material

The fee schedule of the German Chamber of Patent Attorneys applies to the contractual relationship. - Place of jurisdiction for performance and payment ι Berlin-Charlottenburg or Nuremberg.

Strips put on, which after the inside of the pillow through any appropriate funds can be drawn. Will be renewed now the strip is united with the cover by a seamless process, in particular by gluing, sealing or polymerizing, with the applied strip in cross section (i.e. perpendicular to the fold) has the shape of a T, the base of which is twice as thick possesses, and its two arms, which form the portion of the strip placed directly on the cover, with one another are preferably united at the point of their connection with the foot by a seam along the whole strip.

The innovation is below with reference to the drawing explained by way of example.

Fig. 1 shows diagrammatically a vehicle seat, the seat surface and backrest each have a fold produced according to the innovation.

Fig. 2 shows diagrammatically on a larger scale, with parts being broken away, the components of one of these folds »

Fig. 3 schematically shows another embodiment of the same Palte.

In the illustrated embodiment, for example, in a seat 1 (Figo 1) of a vehicle seat 2 has a re-entrant fold 3 are formed, which are parallel to the front edge 4 of the seat surface is, so that between the fold 3 and the edge 4- a bead 5 arises, which the thighs of the seated people comfortably supports and at the same time prevents them from sliding forward.

It is "already" known to have such a palte in a seat cushion to manufacture. For this purpose, a canvas strip is sewn onto the back of the cover of the cushion along the palette to be formed and by means of a rod arranged in the strip and with the help of cords or cables attached to this rod and to the device position of the pillow are attached, pulled towards the inside of the pillow.

This sewing the strip to the coating has the following parts in Geesthacht%

When the stitches are protruding on the outside of the cover the palte is not continuous and has to be covered with a braid if its irregularities are uncomfortable to touch and look at should be covered.

If the stitches don't protrude on the outside, which is difficult to get right in practice, the joint is not tight enough between the canvas and the cover, which mechanically weakens the panel.

In order to remedy these disadvantages, the strip placed on the cover by a seamless process in which an adhesive, sealing, polymerizing process or the like is used will.

In order to be able to accommodate the rod 7 in the strip 6 (Pig. 2) ; on which the pull is exerted without the risk of separation occurring, this strip can be given the shape of a T-profile, the butt 6 of which is twice as thick, the two

the layers of the puss in the immediate vicinity of their connection 6p on the legs 6 ^ of the T are firmly united with one another.

The rod 7 is arranged in the base of the foot 6, and the two legs 6 are in the manner mentioned (seamlessly) on the Back of the cover 8 put on.

With a preferred in Pig. 2, the strip 6 is made of canvas and the cover 8 is made of synthetic leather (ie it consists of a plastic layer which adheres to a layer of textile material), and the connection of the two parts of the strip in the connection zone 6 _? takes place through a · seam 3, while the attachment of the legs 6? of the strip on the coating is produced by a layer of joiner's glue 10, for example by means of glue sold under the name Texticroche by the company of the same name in Aubervilliers (France).

However, Ss also falls within the scope of the innovation, the stripes

and / or to produce the coating from any flexible material other than those specified above, and connecting the two parts of the strip to one another at 6p and / or connecting the two legs of the strip to the coating by sealing, in particular with high frequency, polymerizing, etc. to produce.

After the strip 6 has been attached to the cover 8, it is sufficient to fasten the strip, for example with the aid of hooks or cords, which on the one hand are attached to the rod 7 and on the other hand to the frame of the pillow, to pull inside the pillow to the desired Form 3 fold. The powerful union of the two

Legs of the strip in the zone of their common connection with the foot prevents any detachment by spreading the legs in this zone when exercising the train.

Me volume lying on both sides of Pusses G ^ are generally filled with an elastic foam material which itself rests on metal springs.

The cross-section of the strip can have a shape deviating from the T-shape.

This cross-section can, for example, have the shape of a V or an L, as shown in Fig. 3, the strip 11 then being the general Has the shape of an angle.

In this latter case, the strip 11, which can be double or single, suitably consists of plastic and is through Seal attached under layer 8 along a continuous or discontinuous line 12 which is near the edge of the angle and the fold 3 lies. The high-frequency method can be used to carry out this sealing, if the strip consists of plasticizing polyvinyl chloride, or that with "Heat pulses" working method when the strip is out of the the same material or made of polyethylene, polyamide, etc.

If the strip 11 is simple, the rod for fastening the clamping parts can be by a series of hooks 13 of any type and Shape to be replaced.

The method according to the innovation thus allows the economic '

-6-

Manufacture of a mechanically not weakened palette, which is completely continuous and smooth and therefore pleasant to the touch and is to be seen.

The innovation can of course be modified. So in particular the cushion provided with a pallet according to the innovation is an article different from a seat for motor vehicles be e.g. a backrest for seats (see line 14 in Pig. 1), an armrest, a mattress, etc. «

Perner, such a cushion can have several such parallel- or have non-parallel gaps.

After all, the gaps do not need to be straight, but can, for example, be curved, broken or other shaped lines form.
