Vehicle seat with form-adjustable side wings
A vehicle seat has a seat cushion upholstery part and a backrest upholstery part, and the 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 5 supporting a vehicle seat occupant. Further, 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, and a wear-resistant fabric is embedded two-dimensionally into the foam of the at least one foam upholstery portion for its stabilization and at least partially covering the at least one embedded cushion, and, in at least one 10 part of the area covered by the wear-resistant fabric, the fibers of the wear-resistant fabric are oriented at a non-zero-degree angle to the seat width direction.
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 a seat width direction and at least one upholstery portion into which the at least one cushion is embedded,
wherein a fiber fabric is embedded two-dimensionally into a foam material of the at least one upholstery portion for its stabilization and at least partially covering the at least one embedded cushion, and wherein, in at least one part of an area covered by the fiber fabric, fibers of the fiber fabric are oriented at a non-zero-degree angle to a plane extending in the seat width direction and in an elevation direction of the side bolster, and
wherein the fiber fabric comprises an inner partial area and an outer partial area joined together at a midsection of an edge of the fiber fabric, wherein the shape of the inner partial area of the fiber fabric, in the seat width direction, is fashioned to the shape of the corresponding side of the cushion, while the outer partial area overlaps the edge of the fiber fabric such that protruding sections of the outer partial area can be folded over the edge of the fiber fabric towards the inner side of the seat in the seat width direction, where the protruding sections then overlap with the inner partial area.
2. The vehicle seat according to claim 1 , wherein in at least part of the area covered by the fiber fabric, the fibres fibers of the fiber fabric are at an angle of between 15° and 75° 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 2 , wherein in at least part of the area covered by the fiber fabric, the fibers of the fiber fabric are at an angle of between 25° and 65° to the plane extending in the seat width direction and in the elevation direction of the side bolster.
4. The vehicle seat according to claim 2 , wherein in at least part of the area covered by the fiber fabric, the fibers of the fiber fabric are at an angle of between 40° and 50° to the plane extending in the seat width direction and in the elevation direction of the side bolster.
5. The vehicle seat according to claim 1 , wherein the fiber fabric is a mesh grid with parallelogram-shaped, diamond-shaped, rectangular or square meshes.
6. 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 portion of which has, on an inner side of the side bolster, a hollow space tapering in the elevation direction extending towards an edge of the hollow space into which the at least one cushion is embedded such that two sides of the upholstery portion are pressed apart relative to the edge of the hollow space upon deformation of the cushion.
7. The vehicle seat according to claim 6 , wherein the fiber fabric is embedded adjacent to the at least one cushion on a reverse side of the upholstery portion.
8. The vehicle seat according to claim 1 , wherein the respective at least one cushion is designed as being inflatable.
9. The vehicle seat according to claim 8 , wherein a pump apparatus is connected via a hose line to the respective at least one cushion in order to pump a fluid into the cushion and out of the cushion.
10. The vehicle seat according to claim 9 , wherein the fluid is compressed air.
11. The vehicle seat according to claim 8 , wherein the cushion comprises two partial chambers extending lengthwise in the elevation direction of the upholstery portion, wherein the two partial chambers are joined in the elevation direction of the upholstery portion such that the upholstery portion is pressed laterally outward upon filling.
12. The vehicle seat according to claim 1 , wherein the fiber fabric comprises a plastic or textile material.
