Definitions

  • the invention relates to a pneumatic cushion consisting of several air chambers, preferably a back cushion for seats in motor vehicles.
  • the invention also relates to those cushions in which the parts (hollow bodies) of the cushion forming the air chambers are connected to one another at their edges to the adjacent chambers.
  • a pneumatic cushion of this type is described in FR-A-15 06 319.
  • the upholstery known from this publication consists of a middle part and two side parts. There is an elongated air chamber in each of the side parts, while an approximately square, strip-shaped air chamber is arranged in the middle part and an air chamber is elongated in the transverse direction.
  • the wall parts which bind the air chambers are connected to one another at their edges to the adjacent chambers over the entire length of the edges.
  • the aforementioned wall parts of the chambers are connected to one another via their edges, mutual interference between the individual chambers cannot be avoided; the swelling of the chambers causes a reduction in width, which affects neighboring chambers and leads to a distortion of the chamber structure. This is particularly the case with the chambers which are located on the edges of the cushion, e.g. with back pads in the kidney area of the user.
  • the invention has for its object to improve the above cushion so that the individual chambers inflated form a coherent whole, without having to fear that adjacent chambers adversely affect by deformation.
  • the figure shows a half of a back cushion for a motor vehicle seat in the view.
  • the cushion is arranged on the backrest of the vehicle seat in such a way that the two superimposed chambers 1 and 2 of the pneumatic cushion, which consists essentially of rubber or rubber-like substances, are arranged in or close to the lumbar region of the user.
  • the two chambers thus extend transversely to the seat.
  • the chambers 1 and 3 can be charged with air via connections 4. For these reasons, hose connections (not shown in more detail) are usually provided there.
  • socket chambers 3 are attached to the chamber 2 only at the upper edge and to the lower edge of the chamber 1.
  • the attachment points are designated 5, 6.
  • a narrow shield 7 is located between these fastening points 5, 6.
  • Appropriate attachment is also provided for chambers 1 and 2. These attachment points are designated 8. Accordingly, there is a continuous horizontal slot 9 between them.
