The invention relates to an upholstery body with a rubberized one made of rubber hair, rubber fibers Hair and / or fibers or the like and formed on all sides by a foam-molded jacket surrounded core.

The production of such a known upholstery body is due to the foamed one-piece, all-round closed jacket difficult, cumbersome and expensive, because that Fixing the floating core in order to look around the foam cover is not easy can be accomplished and requires a correspondingly great deal of care. Nevertheless, the foam pushes the core from the desired position and changed the height and / or lateral position of the same, so that at the covering is different for each upholstered body. It is not possible to use upholstery uniform shape in efficient mass production.

Since the core consists of loose fiber material, this cushioned body can also be used in the event of a high pressure load or, in the event of prolonged use, sit through relatively easily in a disadvantageous manner and deform.

If, in other upholstery bodies known in practice, a dimensionally stable upholstery core is present is, is missing a durable and yet sufficiently flexible, easy to manufacture and around the The core can be arranged easily and without much manual work. "

The object of the invention is to create an upholstered body while avoiding such deficiencies, which can be produced as a mass-produced item largely without manual labor in a simple manner with a uniform shape and has significantly improved loading properties.

According to the invention, the core of an upholstered body is of the type mentioned at the beginning in a known manner by pressing or the like. Compressed and deformed and the jacket off two preformed foam trays or from a preformed tray and a lid educated.

Furthermore, for edge reinforcement, it is preferred to provide the core with profiles on the side of the edge, which the shells inside are adapted. It is also possible to get a softer one Upholstery body a foam shell with inner profiles such as humps, cams, ribs or the like. Equip.

In order to achieve certain cushioning properties, the foam shells and are in each coat Upholstered body

optionally the lid · each formed from a material of different hardness.

In addition, the two foam shells of a cushioned body can be used to adapt to the inner Have outer troughs core.

Exemplary embodiments of the invention are shown in the drawings. It shows

1 shows a perspective view of individual parts arranged one above the other in an exploded view one formed from a central upholstery core and a split coat that surrounds it on all sides Upholstered body, partially cut,

Fig. 2 is a perspective view of a modified upholstery body with molded shells made of the same formed core sheathing and a cushion core designed as a molded piece, partially cut,

F i g. 3 a perspective view of an upholstered body shell with bottom profiling on the inside, partially cut,

4 shows a perspective view of an upholstery molded shell with modified internal pronation, partially cut.

A plate-shaped cushion body 10 is made up of a central cushion core 11 and one of these on all sides surrounding, multi-part jacket 12 formed (see. Fig.l).

The cushion core preferably consists of a plate-shaped, flat fleece, which is made of rolled and gummed or the like hair, made from plant or synthetic fibers and pressed or the like. Is compressed to a certain, resilient stiffness and strength in a manner known per se.

The jacket 12 is designed as soft upholstery, inherently softer and more flexible than the cushion core 11 and consists of a foam shell 12 a and a foam cover 12 b fitted therein.

The shell 12 a is box-like with laterally circumferential walls that fix the cushion core 11 laterally 13 built. In the upper, inside edge

Claims (4)

Rich in the walls 13 there is a fold 14 for receiving the cover 12 6. The formation of the fold 14 is determined by the cover 12 b which surrounds it. Both parts 12 a and 12Z) made of foam fit into one another and are glued to one another by means of binding agents after inserting the cushion core 11. While the shell 12 α is formed by a foamed molded part, the cover 12 6 that can be inserted therein can consist of a foam sheet or a foam tape cut to length (by the meter). A further modified cushion body 17 has a central (inner) cushion core 18 designed as a molded part with circumferential profilings 19 protruding over both mutually parallel support surfaces (cf. FIG. 2). This cushion core 18 is surrounded by a jacket 20 formed on two advantageously identically shaped foam shells 20 a, the inner shape of which adapts to the cushion core 18. Each shell 20 a shows on both support sides an outer trough 21, which is embedded between a circumferential support edge and largely adapted to the inner cushion core 18. soft center and a somewhat harder (more form-solid) edge zone results. Further modified molded shells 22 and 23 for the cushion core sheathing are shown in FIG. 3 and 4. These molded shells 22 and 23, which are also made of foam, have profiles such as cams 24, ribs 25 and the like on the inside bottom surface serving as the cushion core support surface, which run in a workpiece direction or cross over as ribs 25 Extend the entire surface and form a grid with troughs 26 in between. The molded shells 22 and 23, which are designed as soft upholstery, rest with their profiles on the upholstery core. Due to the increase in material, with a simultaneous substantial increase in volume, in particular an increase in the cushioned body, a softer cushioned body results than when using molded shells with a flat bottom inner surface without a large amount of additional material. It is within the scope of the invention to manufacture the shells or lids forming a cushion core sheathing as foam parts of different hardness. Patent claims: 1. Upholstery body with a core formed from rubber hair, rubber fibers or the like and surrounded on all sides by a foam-molded jacket, characterized in that the core (11 or 18) is compressed or deformed in a known manner by pressing or the like, and the jacket is formed from two preformed foam shells (20a ) or from a preformed shell (12a or 22 or 23) and a cover (126). 2. Upholstered body according to claim 1, characterized in that the core (18) laterally at the edge is provided with profiles (19) to which the shells (20 a or 22 or 23) are adapted inside are. 3. Upholstered body according to claims 1 and 2, characterized in that a foam shell (22 or 23) with inner profiles, such as Hökkern, Cams (24), ribs (25) or the like. Is equipped. 4. upholstered body according to claims 1 to 3, characterized in that in each coat Foam shells (20a or 12a or 22 or 23) and optionally the cover (126) a material of different hardness are formed. 5. cushion body according to claims 1 to 4, characterized in that its two Foam shells (20 a) have outside depressions (21).
