Problems solved by technology

[0003] The known vehicle seat with a shape-variable air cushion for changing the contour of the support surface has proven to be suitable, but has the disadvantage that its construction is particularly complex and therefore expensive, in particular due to the required aerodynamic structure, It usually consists of a pump and corresponding connecting lines for connecting the pump to the air cushion
In addition, in order to ensure the tightness of the pneumatic structure, a great deal of effort is required

Embodiment Construction

[0026] With the help of figure 1 and 2 , an embodiment of the motor vehicle seat 2 according to the invention is described on the basis of the seating part 4 of the motor vehicle seat 2 , wherein the design can also be applied in a similar manner to the not shown backrest part of the motor vehicle seat 2 . In the figures, the direction of travel 6 is marked with a corresponding arrow, while the direction 8 opposite to the direction of travel 6 is likewise marked with a corresponding arrow. Furthermore, the two opposite height directions 10 , 12 and the two opposite transverse directions 14 , 16 of the motor vehicle seat 2 are marked with corresponding arrows.

[0027] The seating part 4 of the motor vehicle seat 2 comprises a central section 18 and two side cheeks 20 or 22 arranged on the central section 18 in the transverse direction 14 or 16 . The two side cheeks 20 , 22 together with the central section 18 form a support surface 24 for supporting a passenger, which is mar...

Abstract

The invention relates to a vehicle seat (2) with a support surface (24) for supporting a passenger and with variable-shape air cushions (26, 28), wherein the contour of the support surface (24) can be passed through the The air cushions (26, 28) vary in shape. According to the invention, a drivable device (38, 40) is provided by means of which the air cushion (26, 28) can be crushed at least partially from the outside in such a way that the shape of the air cushion (26, 28) changes. Furthermore, the invention relates to a motor vehicle with such a motor vehicle seat (2).

Description

technical field [0001] The invention relates to a motor vehicle seat with a support surface for supporting a passenger and a shape-variable air cushion, wherein the contour of the support surface can be changed by changing the shape of the air cushion. Background technique [0002] US 2007 / 0057551 A1 describes a motor vehicle seat with a support surface which is formed by the seating part of the motor vehicle seat and serves to support a passenger. A shape-variable, inflatable air cushion is arranged inside the seating part of the known car seat. Here, the air cushion is arranged between two hinge-like interconnected plates. There is also a pump for inflating and / or deflated the air mattress. In order to change the contour of the seating surface of the seat part, the air cushion is inflated by means of aerodynamics, so that one plate pivots relative to the other, wherein the pivoted plate also acts on the seating part of the vehicle seat in such a way that the support The...
