Abstract

A motor vehicle seat is provided with a backrest which can be pivoted from a substantially upright position of use into a substantially horizontal position of non-use. The backrest includes, but is not limited to a wing rest which in the position of non-use of the backrest can be pivoted from a lower armrest position of non-use about a pivot axis extending in seat direction into an upper armrest position of use to form an armrest. The wing rest includes, but is not limited to a support part as well as an upholstery part and between the support part and the upholstery part a height adjusting device for the height adjustment of the upholstery part relative to the support part is arranged.

Claims (34)

1. A motor vehicle seat, comprising:

a backrest adapted to be pivoted about a first pivot axis from a first backrest position into a second backrest position, wherein the first backrest position is a substantially upright position of use and the second backrest position is a substantially horizontal position of non-use relative to a seat extending in a seat direction; and

a wing rest coupled to the backrest and, when the backrest is in the second backrest position, adapted to be pivoted from a lower armrest position about a second pivot axis extending in the seat direction into an upper armrest position of use to form an armrest,

wherein, when the backrest is in the first backrest position, the wing rest is arranged on a transverse side of the backrest relative to the seat direction;

wherein the wing rest comprises

a support part,

an upholstery part,

a height adjusting device between the support part and the upholstery part adapted for a height adjustment of the upholstery part relative to the support part, wherein the support part is pivotally supported on the backrest for rotation about the second pivot axis; and wherein the backrest has a front side in the first backrest position, wherein a front side of the upholstery part is generally coplanar with the front side of the backrest when the backrest is in the first backrest position, and wherein the front side of the upholstery part forms a top side of the wing rest when the wing rest is in the upper armrest position.

2. The motor vehicle seat according to claim 1 , wherein the height adjusting device can be further configured for height adjustment when the backrest is in the first backrest position.

3. The motor vehicle seat according to claim 1 , wherein the support part is a rigid carrier plate.

4. The motor vehicle seat according to claim 1 , wherein the support part has a support back side and the backrest has a backrest back side, wherein the support back side is configured to be generally co-planar with the backrest back side when the backrest is in the first backrest position and when the backrest is in the second backrest position and the wing rest is in the lower armrest position.

5. The motor vehicle seat according to claim 4 , wherein the support back side faces the backrest back side when the wing rest is pivoted about the second pivot axis in the upper armrest position.

6. The motor vehicle seat according to claim 1 , wherein the height adjusting device in the upper armrest position of the wing rest is arranged below the upholstery part without protruding of from an edge of the upholstery part in a transverse direction relative to the seat direction.

7. The motor vehicle seat according to claim 6 , wherein the height adjusting device in the upper armrest position is arranged entirely below the upholstery part.

8. The motor vehicle seat according to claim 1 , wherein a depression is provided in the upholstery part to at least partially accommodate the height adjusting device when the height adjusting device is in a collapsed position.

9. The motor vehicle seat according to claim 8 , wherein the depression is closed off to the outside through the support part when the height adjusting device is in the collapsed position.

10. The motor vehicle seat according to claim 1 , wherein the height adjusting device comprises at least one of an inflatable or evacuatable cushion between the support part and the upholstery part.

11. The motor vehicle seat according to claim 1 , wherein the height adjusting device comprises a joint quadrilateral with four joint axes.

12. The motor vehicle seat according to claim 11 , wherein the joint quadrilateral comprises a first pivot lever which is arranged capable of being pivoted about a third pivot axis on the support part and also capable of being pivoted about a fourth pivot axis on the upholstery part and comprises a second pivot lever which is arranged capable of being pivoted about a fifth pivot axis on the support part and also capable of being pivoted about a sixth pivot axis on the upholstery part.

13. The motor vehicle seat according to claim 12 , wherein the third pivot axis, the fourth pivot axis, the fifth pivot axis, and the sixth pivot axis of the joint quadrilateral are arranged parallel to one another.

14. The motor vehicle seat according to claim 12 , wherein the third pivot axis, the fourth pivot axis, the fifth pivot axis, and the sixth pivot axis of the joint quadrilateral are arranged at a substantially right angle to the seat direction.

15. The motor vehicle seat according to claim 1 , wherein the wing rest is a first wing rest and the transverse side is a first transverse side relative to a seat direction, and wherein the motor vehicle seat further comprises a second wing rest arranged on a second transverse side of the backrest, wherein the second wing rest is adapted to be pivoted about a third pivot axis.

16. The motor vehicle seat according to claim 15 , wherein the second and third wing rests can be respectively pivoted about the first pivot axis and the second pivot axis independently of each other or are adjustable in height independently of each other.

17. A seat arrangement, comprising:

a first motor vehicle seat, said first motor vehicle seat comprising:

a seat part extending in a seat direction;

a backrest adapted to be pivoted from a first substantially upright position of use into a second substantially horizontal position of non-use;

a wing rest, when the backrest is in the substantially horizontal position, is adapted to be pivoted from a lower armrest position of non-use about a pivot axis extending in seat direction into an upper armrest position of use to form an armrest, wherein, when the backrest is in the substantially upright position, the wing rest is arranged on a transverse side of the backrest relative to the seat direction;

wherein the wing rest comprises

a support part;

an upholstery part;

a height adjusting device between the support part and the upholstery part adapted for a height adjustment of the upholstery part relative to the support part, wherein the support part is pivotally supported on the backrest for rotation about the second pivot axis; and wherein the backrest has a front side in the first backrest position, wherein a front side of the upholstery part is generally coplanar with the front side of the backrest when the backrest is in the first backrest position, and wherein the front side of the upholstery part forms a top side of the wing rest when the wing rest is in the upper armrest position; and

a second motor vehicle seat that is arranged in a seat row next to the first motor vehicle seat, wherein the wing rest is arranged on a side of the first motor vehicle seat between the backrest and the second motor vehicle seat.

18. The seat arrangement according to claim 17 , wherein further comprising a third motor vehicle seat is provided in the seat row, wherein the first motor vehicle seat is arranged between the second motor vehicle seat and the third motor vehicle seat.
