Abstract

A vehicle seating assembly includes a seat base. A thigh support is pivotally coupled to and extends forward from the seat base. The thigh support is spring-biased relative to the seat base to a raised position. A lever is operably coupled to a center portion of the thigh support by a hinge. The lever is spring-biased to a raised position relative to the thigh support and includes a rack with a plurality of teeth proximate the hinge. The teeth of the rack are configured to engage a catch projecting from the seat base. A handle extends transversely from the lever. The handle is operable to disengage the rack from the catch.

Claims

1. A vehicle seating assembly comprising:

a seat base;

a thigh support pivotally coupled to and extending forward from the seat base, the thigh support being spring-biased relative to the seat base to a raised position;

a bracket member disposed under the thigh support and defining an enlarged opening through which a support rod extends, the bracket limiting vertical movement of the thigh support;

a lever operably coupled to a center portion of the thigh support by a hinge, the lever being spring-biased to a raised position relative to the thigh support and including a rack with a plurality of teeth proximate the hinge, the teeth of the rack being configured to engage a catch projecting from the thigh support; and

a handle extending transversely from the lever, the handle operable to disengage the rack from the catch.

2. The vehicle seating assembly of claim 1, wherein the thigh support is pivotally coupled to the seat base via a piano-type hinge mechanism.

3. The vehicle seating assembly of claim 2, further comprising:

a hinge pin extending through the piano-type hinge mechanism; and

springs disposed on opposing ends of the hinge pin.

4. The vehicle seating assembly of claim 1, wherein the teeth of the rack are configured to position the thigh support at an angle of 0, 3, 6, 9, and 12 degrees relative to the seat base.

5. The vehicle seating assembly of claim 1, wherein the lever includes a widened rear portion operably coupled to the hinge and a narrow forward portion coupled to the handle.

6. The vehicle seating assembly of claim 1, wherein the teeth of the rack extend laterally a distance approximately equal to a width of the hinge.

7. The vehicle seating assembly of claim 1, wherein the thigh support includes a lateral portion and a vertical portion, and wherein the vertical portion forms the catch.

8. A vehicle seating assembly comprising:

a forward thigh support pivotally coupled to a seat base;

a lever coupled to the thigh support via a hinge and having a plurality of teeth;

first and second elongate catch members projecting downward from the thigh support and engaged with the teeth;

spring members disposed on the hinge that bias the lever to a raised position; and

a handle operable to disengage the teeth from the elongate catch members.

9. The vehicle seating assembly of claim 8, wherein the thigh support is pivotally coupled to the seat base via a piano-type hinge mechanism.

10. The vehicle seating assembly of claim 9, further comprising:

a hinge pin extending through the piano-type hinge mechanism; and

springs disposed on ends sides of the hinge pin, the springs biasing the lever to a raised position.

11. The vehicle seating assembly of claim 8, wherein the teeth are configured to position the thigh support at an angle between 0 and 12 degrees relative to the seat base.

12. The vehicle seating assembly of claim 8, wherein the lever includes a widened rear portion operably coupled to the hinge and a narrow forward portion coupled to the handle.

13. The vehicle seating assembly of claim 8, wherein the teeth are disposed in a rack that extends laterally a distance approximately equal to a width of the hinge.

14. The vehicle seating assembly of claim 8, wherein the thigh support includes a lateral portion and a vertical portion, and wherein the vertical portion forms the catch.

15. A vehicle seating assembly comprising:

a seat base;

a forward thigh support pivotally coupled to the seat base, the thigh support being spring-biased to a raised position;

a lever hingedly coupled to the thigh support and spring-biased to a raised position, the lever including teeth engaged with a catch projecting from the seat base; and

a handle extending from the lever and operable to disengage the teeth from the catch, wherein the teeth are disposed in a rack that extends laterally a distance approximately equal to a width of a hinge.

16. The vehicle seating assembly of claim 15, wherein the teeth are configured to position the thigh support at an angle between 0 and 12 degrees relative to the seat base.

17. The vehicle seating assembly of claim 15, wherein the lever includes a widened rear portion operably coupled to a hinge and a narrow forward portion coupled to the handle.

18. The vehicle seating assembly of claim 17, wherein the widened rear portion is operably coupled to the narrow forward portion via an angled transitional portion.

19. The vehicle seating assembly of claim 15, wherein the rack includes a stop at a forward portion thereof that limits over rotation of the catch.
