Abstract

The invention relates to a vehicle seat with a seat cushion upholstery part and a backrest upholstery part, wherein said seat cushion upholstery part and/or backrest upholstery part is bordered on each of the left and right sides by a deformable side bolster for supporting a vehicle seat occupant, wherein each side bolster comprises at least one cushion deformable in the seat width direction and at least one upholstery portion into which the at least one cushion is embedded, wherein a wear-resistant fabric is embedded two-dimensionally into the foam of the at least one foam upholstery portion for its stabilisation and at least partially covering the at least one embedded cushion, and wherein, in at least one part of the area covered by the wear-resistant fabric, the fibres of the wear-resistant fabric are oriented at a non-zero-degree angle to the seat width direction.

Claims

1. A vehicle seat comprising:

a seat cushion upholstery part and a backrest upholstery part, wherein said seat cushion upholstery part and/or backrest upholstery part is bordered on each of the left and right sides by a deformable side bolster for supporting a vehicle seat occupant, wherein each side bolster comprises at least one cushion deformable in the seat width direction and at least one upholstery portion into which the at least one cushion is embedded,

wherein a fibre fabric is embedded two-dimensionally into the foam of the at least one foam upholstery portion for its stabilisation and at least partially covering the at least one embedded cushion, and wherein, in at least one part of the area covered by the fibre fabric, the fibres of the fibre fabric are oriented at a non-zero-degree angle to the plane extending in the seat width direction and in the elevation direction of the side bolster.

2. The vehicle seat according to claim 1,

wherein in at least part of the area covered by the fibre fabric the fibres of the fibre fabric are at an angle of between 15°

and 75°

, preferably between 25° and

65°

, and even more preferably between 40° and

50°

to the plane extending in the seat width direction and in the elevation direction of the side bolster.

3. The vehicle seat according to claim 1,

wherein the fibre fabric is a mesh grid with parallelogram-shaped, diamond-shaped, rectangular or square meshes.

4. The vehicle seat according to claim 1,

wherein the respective side bolster is designed as an elongated elevation running essentially orthogonally to the seat width direction and the upholstery part of which has, on an inner side, a hollow space tapering in the elevation direction extending towards an edge into which the at least one cushion is embedded such that the two sides are pressed apart relative to the edge of the hollow space upon deformation of the cushion.

5. The vehicle seat according to claim 4,

wherein the fibre fabric is embedded adjacent to the at least one cushion on a reverse side of the upholstery part.

6. The vehicle seat according to claim 1,

wherein the respective at least one cushion is designed as being inflatable.

7. The vehicle seat according to claim 6,

wherein a pump apparatus which is connected via a hose line to the respective at least one cushion in order to pump a fluid, in particular compressed air, into the cushion and out of the cushion.

8. The vehicle seat according to claim 6,

wherein the cushion consists of two partial chambers extending lengthwise in the elevation direction of the upholstery portion, wherein the two partial chambers are joined in hinge-like fashion in the elevation direction the upholstery portion such that the upholstery portion is pressed laterally outward in hinge-like fashion upon filling.

9. The vehicle seat according to claim 1,

wherein the fibre fabric consists of two partial areas joined together in the midsection of the edge wherein the shape of the partial area of the fibre fabric located on the inner side of the seat relative to the respective at least one cushion in the seat width direction, is fashioned to the shape of the corresponding side of the cushion, while the outer partial area in the two outer sections of the edge overlaps in such a way that protruding partial area sections can be folded over the edge onto the inner side, where they then overlap with the other partial area section.

10. The vehicle seat according to claim 1,

wherein the fibre fabric consists of a plastic or textile material.
