Definitions
- the invention relates to a pneumatic cushion, consisting essentially of rubber or rubber-like substances, for installation in the lower part of a backrest of a motor vehicle seat equipped with two edge beads, the pneumatic cushion having two superimposed, horizontally extending chambers extending transversely to the seat .
- US Pat. No. 3,326,601 dated July 28, 1965 describes a seat back for automobiles with a plurality of horizontally extending air chambers which, in addition to the well-known steel spiral springs, are arranged in the lower part of the backrest between the springs and the cover padding.
- Each air chamber has a connection for a pressure hose.
- the coulter of pressure hoses is guided downwards on one side edge of the backrest.
- Fr-A-1 506 319 dated 5.5.1966 describes a backrest padded with foam, provided with air chambers which are integrated directly into the foam.
- the air chambers are predominantly arranged in the longitudinal direction of the backrest and extend into the vicinity of the lower edge of the backrest, so that the hose connection directly at the lower end of the backrest is made possible for them.
- a duct is provided to supply pressure to the horizontal air chamber arranged at the top.
- the object is achieved in that on both sides of the horizontally extending chambers one perpendicular to each other, extending in the longitudinal direction of the backrest essentially over the height of these chambers, further chamber is arranged in that the compressed air connection of each chamber is at the lower end of the pneumatic cushion , wherein the upper, transverse chamber encloses the lower, shorter chamber symmetrically laterally via narrow extensions and one of the two symmetrical extensions assumes the compressed air connection of the upper chamber.
- a divided chamber acts on the back of the seated person in a similar way to two separate chambers, since the curvature is similar. With the upper partitioned chamber, the two superimposed chambers effectively behave like three superimposed ones. Compared to three separate chambers one above the other, however, this arrangement has the advantage of a more complex pressure supply.
- the backrest has in the middle an essentially flat contact surface 1 which extends essentially over the height of the backrest, on both sides of which in the edge region of the backrest beads 2 which likewise extend to the upper edge of the backrest. It is understood that the backrest can be provided with a headrest at the upper edge. Approximately in the lower part of the contact surface 1, in the height extending about a third of the backrest height, is built into the backrest, below the cover and a cover, a substantially square or rectangular pneumatic cushion in plan, which by not shown Fasteners are secured against slipping.
- This pillow shown in more detail in FIG. 2, essentially made of rubber or rubber-like substances, has in its central region two transverse chambers 3 and 4 arranged one above the other, the upper chamber 4 being divided into two chamber regions 6, 7 by a transverse web 5 the dependent claim 2 is divided.
- the chamber 3 has a compressed air connection 9; the side chambers 8 have a compressed air connection 10 and 11.
- the compressed air connection for the chamber 4 is designated by 12.
- All hose connections start from the lower edge of the cushion, and it goes without saying that the laying of these hoses from the backrest to a compressed air source or control means is considerably simplified.
- the connections 9, 10 and 12 are immediately adjacent on one side of the cushion.
- the compressed air connection 11 for the opposite chamber 8 is arranged on the associated edge of the cushion.
- the chamber 4 has an extension 14 which extends to the lower edge of the cushion. Parts of the chamber 4 enclose the chamber 3 on both sides for reasons of symmetry, so that there are two extensions 13, 14, of which the left 13 ends as a sack extension and the right 14 as a passage to the compressed air connection 12.
