Abstract

A seat trim cover management system for seat cushion length adjustment includes a seat cushion base having stationary portion and an adjustable portion wherein the stationary portion and the adjustable portion include a horizontal top surface and a vertical front surface. An adjustment mechanism is in mechanical communication with the stationary portion and the adjustable portion and is configured to manipulate the adjustable portion. A cover material includes a first end attached to the horizontal top surface of the stationary portion or the adjustable portion, and at least one seat cover management system is attached to a second end of the cover material and is configured to maintain tension between the first end and second end of the cover material while the cover material shrouds the gap created between the stationary portion and the adjustable portion when at the extended position.

Claims

1. A seat trim cover management system for seat cushion length adjustment comprising:

a seat cushion base having stationary portion and an adjustable portion wherein the stationary portion and the adjustable portion include a substantially horizontal top surface and a substantially vertical front surface;

an adjustment mechanism in mechanical communication with the stationary portion and the adjustable portion configured to move the adjustable portion from a retracted position to an extended position relative to the stationary portion, wherein a gap is created between the stationary portion and the adjustable portion when at the extended position;

a seat trim cover material having a first end attached to the substantially horizontal top surface of the stationary portion or the adjustable portion; and

at least one seat trim cover management system attached to a second end of the seat trim cover material configured to maintain tension between the first end and second end of the seat trim cover material while the seat trim cover material shrouds the gap created between the stationary portion and the adjustable portion when at the extended position.

2. The system of claim 1 wherein the adjustment mechanism is manually operable.

3. The system of claim 1 wherein the adjustment mechanism is electrically operable.

4. The system of claim 1 wherein the seat trim cover management system comprises a spring roller.

5. The system of claim 4 wherein the first end of the seat trim cover material is attached to the substantially horizontal surface of the adjustable portion and the spring roller is disposed on the stationary portion.

6. The system of claim 4 wherein the first end of the seat trim cover material is attached to the substantially horizontal surface of the stationary portion and the spring roller is disposed on the adjustable portion.

7. The system of claim 4 wherein the seat trim cover management system further comprises a roller bar.

8. The system of claim 7 wherein the first end of the seat trim cover material is attached to the substantially horizontal surface of the stationary portion, the roller bar is disposed on the adjustable portion, and the spring roller is disposed on the stationary portion wherein the seat trim cover material traverses the roller bar when the adjustment mechanism is manipulated.

9. The system of claim 7 wherein the first end of the seat trim cover material is attached to the substantially horizontal surface of the adjustable portion, the roller bar is disposed on the stationary portion, and the spring roller is disposed to the adjustable portion wherein the seat trim cover material traverses the roller bar when the adjustment mechanism is manipulated.

10. The system of claim 7 wherein the roller bar further comprises sprockets fixed on opposing ends configured to engage corresponding perforations at outside edges of the seat trim cover material when the adjustable portion is moved.

11. A seat trim cover management system for seat cushion length adjustment comprising:

a seat cushion base having stationary portion and an adjustable portion wherein the stationary portion and the adjustable portion include a substantially horizontal top surface and a substantially vertical front surface;

an adjustment mechanism in mechanical communication with the stationary portion and the adjustable portion configured to move the adjustable portion from a retracted position to an extended position relative to the stationary portion, wherein a gap is created between the stationary portion and the adjustable portion when at the extended position;

a seat trim cover material having a first end attached to the substantially horizontal top surface of the stationary portion or the adjustable portion; and

a spring roller attached to a second end of the seat trim cover material configured to maintain tension between the first end and second end of the seat trim cover material while the seat trim cover material shrouds the gap created between the stationary portion and the adjustable portion when at the extended position.

12. The system of claim 11 wherein the adjustment mechanism is manually operable.

13. The system of claim 11 wherein the adjustment mechanism is electrically operable.

14. The system of claim 11 wherein the first end of the seat trim cover material is attached to the substantially horizontal surface of the adjustable portion and the spring roller is disposed on the stationary portion.

15. The system of claim 11 wherein the first end of the seat trim cover material is attached to the substantially horizontal surface of the stationary portion and the spring roller is disposed on the adjustable portion.

16. The system of claim 11 further comprising a roller bar.

17. The system of claim 16 wherein the first end of the seat trim cover material is attached to the substantially horizontal surface of the stationary portion, the roller bar is disposed on the adjustable portion, and the spring roller is disposed on the stationary portion wherein the seat trim cover material traverses the roller bar when the adjustment mechanism is manipulated.

18. The system of claim 16 wherein the first end of the seat trim cover material is attached to the substantially horizontal surface of the adjustable portion, the roller bar is disposed on the stationary portion, and the spring roller is disposed to the adjustable portion wherein the seat trim cover material traverses the roller bar when the adjustment mechanism is manipulated.

19. The system of claim 11 wherein the roller bar further comprises sprockets fixed on opposing ends configured to engage corresponding perforations at outside edges of the seat trim cover material when the adjustable portion is moved.
