Abstract

A vehicle seating assembly includes a seatpan coupled with a track assembly that has a rail and a slide. The vehicle seating assembly also includes a cushion assembly that has a movable cushion and a base cushion with a slot. The movable cushion is slidable between a forward position and a rearward position on the seatpan. In addition, the vehicle seating assembly includes a coverstock with a first portion that is disposed over a movable cushion. The coverstock also has a second portion that is disposed between the seatpan and the cushion assembly. The second portion of the coverstock is withdrawn through the slot when the movable cushion moves to the forward position. A gap is defined by the area between the base cushion and the movable cushion in the forward position. The gap is concealed by the coverstock when the movable cushion is in the forward position.

Claims

1. A vehicle seating assembly, comprising:

a seatpan;

a cushion assembly having a one-piece base cushion with a slot defined between front and rear sections thereof and a movable cushion slidable on the seatpan between a rearward position abutting the front section and a forward position that defines a gap between the base and movable cushions; and

a coverstock having a first portion disposed over the movable cushion and a second portion withdrawn through the slot when the movable cushion moves to the forward position concealing the gap.

2. The vehicle seating assembly of claim 1, wherein the coverstock includes a distal end coupled to a retention mechanism, and wherein the retention mechanism draws the second portion through the slot when the movable cushion moves to the rearward position.

3. The vehicle seating assembly of claim 2, wherein the retention mechanism includes a spring-loaded roller.

4. The vehicle seating assembly of claim 2, wherein the retention mechanism maintains tension on the second portion when the movable cushion moves to the forward position.

5. The vehicle seating assembly of claim 1, wherein the base cushion is fixedly coupled to the seatpan.

6. The vehicle seating assembly of claim 1, wherein the coverstock includes a bulbous edge that is retained in a channel defined in at least one side of a side cushion.

7. The vehicle seating assembly of claim 1, wherein the slot includes a substantially rigid vertical support and an unrestricted passage for the coverstock when the base cushion is loaded to a limit.

8. A vehicle seating assembly, comprising:

a seatpan;

a one piece base cushion on the seatpan with front and rear sections defining a slot extending vertically therebetween;

a movable cushion moveable forward and rearward relative to the base cushion; and

a coverstock having a first portion disposed over the movable cushion and a second portion withdrawn through the slot when the movable cushion moves forward, spanning over a gap between the base and moveable cushions.

9. The vehicle seating assembly of claim 8, wherein the coverstock includes a distal end coupled to a retention mechanism, and wherein the retention mechanism draws the second portion through the slot when the movable cushion moves to the rearward position.

10. The vehicle seating assembly of claim 9, wherein the retention mechanism maintains tension on the second portion when the movable cushion moves to the forward position.

11. The vehicle seating assembly of claim 9, wherein the retention mechanism includes a spring-loaded roller.

12. The vehicle seating assembly of claim 9, wherein the retention mechanism includes a rigid shaft extending in a rear direction from the movable cushion beyond the slot and coupled with the distal end.

13. The vehicle seating assembly of claim 9, wherein the retention mechanism includes a top rack coupled to the movable cushion, a bottom rack coupled to the coverstock, and a pinion gear rotatably coupled to the vehicle seating assembly and disposed between the top rack and the bottom rack, wherein rotation of the pinion gear translates the bottom rack in a rearward direction and withdraws the second portion of the coverstock.

14. The vehicle seating assembly of claim 8, wherein the second portion of the coverstock is spring-biased.

15. The vehicle seating assembly of claim 8, wherein the movable cushion abuts the base cushion when the movable cushion is in the rearward position.

16. The vehicle seating assembly of claim 8, further comprising:

a gap defined by the area between the base cushion and the movable cushion in the forward position, wherein the gap is concealed, at least partially, by the coverstock.

17. The vehicle seating assembly of claim 8, wherein the coverstock includes a bulbous edge that is retained in a channel defined in at least one side of a side cushion.

18. The vehicle seating assembly of claim 8, wherein the slot includes a substantially rigid vertical support and an unrestricted passage for the coverstock when the base cushion is loaded to a limit.

19. A vehicle seating assembly, comprising:

a seat base having a single piece with a slot defined between a front portion and a rear portion thereof;

a seat extension movable between a rearward position and a forward position defining a gap between the front portion and the seat extension;

a coverstock having a first portion disposed over the seat extension and a second portion released from an area below an upper surface of the seat base when the seat extension moves to the forward position, wherein the gap is concealed by the coverstock spanning generally in a plane of at least one of the upper surface and a top surface of the seat extension; and

a retention mechanism coupled to the coverstock, wherein the retention mechanism draws the second portion downward when the seat extension moves to the rearward position.

20. The vehicle seating assembly of claim 19, wherein the retention mechanism includes a spring-loaded roller.
