Abstract

A vehicle seating assembly includes a seat carrier defining a central opening. A seatback is pivotally coupled to the seat carrier. A seat flexmat is disposed in the central opening and operable between flexed and unflexed conditions. The vehicle seating assembly also includes a first thigh extension that is extendable and rotatable relative to the seat carrier and a second thigh extension that is extendable and rotatable relative to the seat carrier. The first thigh extension includes a first thigh flexmat operable between flexed and unflexed conditions. The second thigh extension includes a second thigh flexmat operable between flexed and unflexed conditions.

First claim

What is claimed is:

1. A vehicle seating assembly comprising:
a seat carrier defining a central opening;
a seatback pivotally coupled to the seat carrier;
a seat flexmat disposed in the central opening and operable between flexed and unflexed conditions;
a first thigh extension that is extendable and rotatable relative to the seat carrier, the first thigh extension including a first thigh flexmat operable between flexed and unflexed conditions; and
a second thigh extension that is extendable and rotatable relative to the seat carrier, the second thigh extension including a second thigh flexmat operable between flexed and unflexed conditions.

2. The vehicle seating assembly of claim 1 , further comprising:
first and second linear actuators operably coupled with the first and second thigh extensions, respectively.

3. The vehicle seating assembly of claim 2 , wherein the first and second linear actuators are disposed below a forward seat pan extending from the seat carrier.

4. The vehicle seating assembly of claim 2 , further comprising:
first and second attachment features integral with the first and second thigh extensions and configured for engagement with the first and second linear actuators, respectively.

5. The vehicle seating assembly of claim 4 , wherein the first and second attachment features are disposed on lower outside corners of the first thigh extension and the second thigh extension.

6. The vehicle seating assembly of claim 1 , wherein the seat flexmat includes undulating portions disposed within the seat flexmat and which assist in flexure of the seat flexmat when moving from the unflexed condition to the flexed condition.

7. The vehicle seating assembly of claim 2 , further comprising:
a flexmat motor operably coupled with the first and second linear actuators.

8. The vehicle seating assembly of claim 1 , further comprising:
a tilting motor for adjusting thigh tilt of the first thigh extension and the second thigh extension.

9. The vehicle seating assembly of claim 1 , wherein the first and second thigh extensions are independently adjustable.

10. The vehicle seating assembly of claim 1 , wherein at least one of the first thigh flexmat and the second thigh flexmat includes increased flexure proximate an interior region of the first thigh flexmat and the second thigh flexmat, as compared to flexure proximate a peripheral region of the first thigh flexmat and the second thigh flexmat.

11. The vehicle seating assembly of claim 1 , wherein said vehicle seating assembly is free of a suspension assembly coupled with the seat carrier.

12. A seating assembly comprising:
a seat carrier defining a central opening;
a seat flexmat disposed in the central opening;
a first thigh extension extendable and rotatable relative to the seat carrier, the first thigh extension including a first thigh flexmat operable between flexed and unflexed conditions; and
a second thigh extension extendable and rotatable relative to the seat carrier, the second thigh extension including a second thigh flexmat operable between flexed and unflexed conditions.

13. The seating assembly of claim 12 , wherein the seat flexmat includes undulating portions disposed within the seat flexmat and which assist in the flexure of the seat flexmat when moving from the unflexed condition to the flexed condition.

14. The seating assembly of claim 12 , further comprising:
a flexmat motor operably coupled with first and second linear actuators.

15. The seating assembly of claim 12 , further comprising:
a tilting motor for adjusting thigh tilt of the first thigh extension and the second thigh extension.

16. The seating assembly of claim 12 , wherein the first and second thigh extensions are independently adjustable.

17. The seating assembly of claim 12 , wherein at least one of the first thigh flexmat and the second thigh flexmat includes increased flexure proximate an interior region of the first thigh flexmat and the second thigh flexmat, as compared to flexure proximate a peripheral region of the first thigh flexmat and the second thigh flexmat.

18. A seating assembly comprising:
a seat carrier defining a central opening;
a seat flexmat disposed in the central opening;
a thigh extension extendable and rotatable relative to the seat carrier, the thigh extension including a thigh flexmat extending over the thigh extension and operable between a flexed condition in which the thigh flexmat arcs upward and an unflexed condition.

19. The seating assembly of claim 18 , wherein the seat flexmat includes undulating portions disposed within the seat flexmat and which assist in flexure of the seat flexmat when moving to from the unflexed condition to the flexed condition.

20. The seating assembly of claim 18 , further comprising:
a linear actuator operably coupling a dynamic end of the thigh flexmat to the seat carrier, the linear actuator configured to move the thigh extension between the flexed condition and the unflexed condition.
