Abstract

The invention relates to a seat cushion arrangement comprising a first cushion member; a second cushion member being adjustable relative to the first cushion member; and a seat depth adjustment device for adjusting the second cushion member relative to the first cushion member along a longitudinal adjustment axis, wherein the seat depth adjustment device in particular comprises an adjustment member to which the second cushion member is fastened and which is adjustable between a foremost position and a rearmost position relative to a guiding member for adjusting the second cushion member relative to the first cushion member; a trim member connected to both the first and second cushion members, which trim member covers a gap between the first and second cushion members at least in the foremost position of the adjustment member and is at least partially retracted into the gap in the rearmost position of the adjustment member; and an elastic member (a) connected to the trim member and to at least one of the guiding member and a seat front part of the seat depth adjustment device and (b) configured to pull the trim member into the gap upon adjustment of the adjustment member from the foremost position towards the rearmost position.

Claims

1. A seat cushion arrangement comprising:

a first cushion member;

a second cushion member being adjustable relative to the first cushion member; and

a seat depth adjustment device for adjusting the second cushion member relative to the first cushion member along a longitudinal adjustment axis,

wherein the seat depth adjustment device comprises

a seat front part;

a guiding member at the seat front part;

an adjustment member to which the second cushion member is fastened and which is adjustable between a foremost position and a rearmost position relative to the guiding member for adjusting the second cushion member relative to the first cushion member;

a trim member connected to both the first and second cushion members, which trim member covers a gap between the first and second cushion members at least in the foremost position of the adjustment member and is at least partially retracted into the gap in the rearmost position of the adjustment member; and

an elastic member (a) connected to the trim member and to at least one of the guiding member and the seat front part and (b) configured to pull the trim member into the gap upon adjustment of the adjustment member from the foremost position towards the rearmost position,

wherein the elastic member comprises at least one end section fixed to an attachment member engaging an edge section of least one of the guiding member and the seat front part thereby connecting the elastic member to at least one of the guiding member and the seat front part.

2. The seat cushion arrangement of claim 1, wherein the attachment member comprises an engagement part clipped to the edge section.

3. The seat cushion arrangement of claim 2, wherein the attachment member comprises a locking catch portion engaging behind a projection at the edge section.

4. The seat cushion arrangement of claim 1, wherein the edge section borders an opening into which the attachment member reaches.

5. The seat cushion arrangement of claim 4, wherein the attachment member engages an edge section of the guiding member bordering an opening in the guiding member.

6. The seat cushion arrangement of claim 5, wherein the opening in the guiding member, at which bordering edge section the attachment member engages, is completely covered by the adjustment member in the rearmost position of the adjustment member.

7. The seat cushion arrangement of claim 1, wherein the end section of the elastic member is sewed or bonded to the attachment member.

8. The seat cushion arrangement of claim 1, wherein the adjustment member is adjustable from the rearmost position to the foremost position in a first direction along the longitudinal adjustment axis and from the foremost position to the rearmost position in a second direction opposite the first direction, and wherein the edge section the attachment member engages lies towards the first direction.

9. The seat cushion arrangement of claim 1, wherein at least one of a flange portion and a cover element is provided which is configured to act on the elastic member upon adjustment of the adjustment member from the foremost position towards the rearmost position for tensioning the elastic member and thereby pulling the trim member into the gap.

10. The seat cushion arrangement of claim 9, wherein the elastic member is deflected at at least one of the flange portion and the cover element at least in the rearmost position of the adjustment member.

11. The seat cushion arrangement of claim 9, wherein the flange portion is an integral part of the adjustment member.

12. The seat cushion arrangement of claim 9, wherein the cover element is a separate component plugged onto an rear edge section of the adjustment member.

13. The seat cushion arrangement of claim 9, wherein the elastic member comprises at least one elongated strap portion and at least one of the flange portion and the cover element is configured to act on the at least one strap portion of the elastic member upon adjustment of the adjustment member from the foremost position towards the rearmost position.

14. The seat cushion arrangement of claim 11, wherein the at least one strap portion comprises the end section fixed to the attachment member.

15. The seat cushion arrangement of claim 1, wherein the elastic member comprises at least one strap portion which comprises the end section fixed to the attachment member and another end section connected to the trim member, wherein a width of at least one section of the at least one strap portion increases along a direction of extension of the strap portion pointing from the end section fixed to the attachment member towards the other end section connected to the trim member.

16. The seat cushion arrangement of claim 15, wherein the at least one section of increasing width has a constant thickness.

17. The seat cushion arrangement of claim 15, wherein the at least one strap portion comprises an end section fixed to the attachment member having a rectangular contour and an end section of greater width which is connected to the trim member and has a triangular contour.

18. The seat cushion arrangement of claim 1, wherein the elastic member comprises at least two strap portions being spaced apart from each other in a direction perpendicular to the longitudinal adjustment axis.

19. A seat cushion arrangement comprising:

a first cushion member;

a second cushion member being adjustable relative to the first cushion member; and

a seat depth adjustment device for adjusting the second cushion member relative to the first cushion member along a longitudinal adjustment axis,

wherein the seat depth adjustment device comprises

a seat front part;

a guiding member at the seat front part;

an adjustment member to which the second cushion member is fastened and which is adjustable between a foremost position and a rearmost position relative to the guiding member for adjusting the second cushion member relative to the first cushion member;

a trim member connected to both the first and second cushion members, which trim member covers a gap between the first and second cushion members at least in the foremost position of the adjustment member and is at least partially retracted into the gap in the rearmost position of the adjustment member; and

an elastic member (a) connected to the trim member and to at least one of the guiding member and the seat front part and (b) configured to pull the trim member into the gap upon adjustment of the adjustment member from the foremost position towards the rearmost position,

wherein the elastic member comprises at least one strap portion comprising a first end section via which the elastic member is connected to at least one of the guiding member and the seat front part and a second end section via which the elastic member is connected to the trim member, wherein the at least one strap portion extends along a direction of extension from the first end section towards the second end section and a width of at least one section of the at least one strap portion increases along the direction of extension.

20. The seat cushion arrangement of claim 19, wherein the elastic member comprises at least two strap portions being spaced apart from each other in a direction perpendicular to the longitudinal adjustment axis.
