摘要 | A sitting and reclining cushion is divided into a seat cushion and a back cushion, which are configured in an essentially identical manner. A sleeve consisting of a textile material with low elasticity contains a plurality of tubular pockets consisting of an identical material and joined longitudinally to said sleeve by means of seams. Each pocket is likewise connected to its neighbour or neighbours by means of seams. Each pocket contains a pouch, which consists of an elastic plastic and comprises a valve, and can be filled with compressed air. As a result, the pockets modify their shape, thus tensioning the sleeve and forming the actual sitting or reclining surface. The optimised shape of the cushion structure can be adapted to individual requirements for comfort by means of different air pressures in the pouches. | ||||||

说明书全文 | This patent application is a continuation of U.S. patent application Ser. No. 10/520,029, filed on Sep. 30, 2005. U.S. patent application Ser. No. 10/520,029 is a national stage application of PCT/CH2003/000200, filed on Mar. 27, 2003. U.S. patent application Ser. No. 10/520,029 and International Patent Application PCT/CH2003/000200 are incorporated herein by reference. 1. Technical Field The present invention relates to an adaptive pneumatic seat cushion and backrest cushion for vehicles and aeroplanes. 2. History of Related Art Pneumatic seat cushions and backrest cushions are known per se. As a rule they comprise a multitude of air tubes, arranged side by side, which can be aerated and de-aerated by way of a common valve, with the design and construction of such pneumatic seat cushions and backrest cushions being similar to that of known air mattresses. Certain adaptation options consist of having different air pressure settings in individual tubes, as a result of which the shape and softness can be varied to a limited extent. For practical application, such cushions are provided with a textile cover. However, the basic structure of the tubes remains visible and—an essential factor in a cushion—can also be felt. It is the object of the present invention to create a seat cushion and backrest cushion that is adaptive within a wide range; meets very high requirements in relation to seating comfort; can achieve noticeable weight savings when compared to conventional foam cushions; and during whose manufacture existing seat shell constructions can easily be taken into account. A more complete understanding of the present invention may be obtained by reference to the following Detailed Description, when taken in conjunction with the accompanying Drawings, wherein: Various embodiments of the present invention will now be described more fully with reference to the accompanying drawings. The invention may, however, be embodied in many different forms and should not be constructed as limited to the embodiments set forth herein; rather, the embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In principle, the design shown in In The above explanations relating to the seat cushion of course equally apply to the backrest cushion 2. The dimensions of the pockets 5, their number and the air pressures to be applied can easily be adapted to the particular requirements to be met so that optimum seat comfort can be achieved. Since seat comfort depends on the body dimensions of the seated person, each pouch 7 inserted in a pocket 5 can individually be filled with compressed air. In this way the basic design, which has been anatomically optimised, can in addition be personally optimised. The fact that form and behavior of seat cushion 1 and backrest cushion 2 are primarily defined by the tensioned shell 4, and the pockets 5 with pouches 7 primarily serve to tension and form the shell is decisive and in accordance with the invention. Attaching the seat cushion 1 and the backrest cushion 2 in a given seat structure or seat shell preferably takes place by two or more adherence-type closure strips which can also be attached to the shell 4 by sewing, and to the seat structure by way of adhesion. Other ways of attachment, such as for example by clamps or buttons, also fall within the scope of this invention. Although various embodiments of the present invention have been illustrated in the accompanying Drawings and described in the foregoing Detailed Description, it will be understood that the invention is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the spirit of the invention as set forth herein. |
