Abstract

A seating assembly for a motor vehicle comprises a flip up lower seat cushion having a design seating position and a structural member having a forward edge pivotally coupled with a floor and a rearward edge disposed proximate a seat frame. A cushion stop assembly is disposed on the structural member and disposed proximate the rearward edge of the structural member. The cushion stop assembly has a catch and an actuator. An inertia hook is pivotally mounted to the seat frame comprising a hook member and a hook stop, the inertia hook further having a first hook position when the actuator acts upon the hook stop to rotate the hook member into vertical alignment with the catch and a second hook position when the actuator is lifted away from the hook stop and the hook member rotates out of vertical alignment with the catch.

First claim

What is claimed is:

1. A seating assembly for a motor vehicle comprising;
a seat frame attached to a floor of the motor vehicle;
a flip up lower seat cushion having a design seating position and an upright forward flipped position comprising a structural member having a forward edge pivotally coupled with the floor and a rearward edge disposed proximate the seat frame;
a cushion stop assembly disposed on the structural member of the flip up lower seat cushion and disposed proximate the rearward edge of the structural member of the flip up lower seat cushion, the cushion stop assembly having a catch and an actuator; and
an inertia hook pivotally mounted to the seat frame comprising a hook member and a hook stop, the inertia hook further having a first hook position when the actuator acts upon the hook stop to rotate the hook member into vertical alignment with the catch and a second hook position when the actuator is lifted away from the hook stop and the hook member rotates out of vertical alignment with the catch.

2. The seating assembly of claim 1 , further comprising an upwardly extending seat back cushion comprising a seat back structural member coupled with the seat frame.

3. The seating assembly of claim 2 , wherein each of the flip up lower seat cushion and the upwardly extending seat back cushion further comprise an upholstered exterior portion supported by the structural member of the flip up lower seat cushion and the upwardly extending seat back structural member, respectively.

4. The seating assembly of claim 1 , wherein the hook stop is disposed rearward of an inertia hook pivot supporting the inertia hook and a center of gravity of the inertia hook is disposed forward of the inertia hook pivot, wherein the actuator has a first actuator position in contact with and acting upon the hook stop to rotate the hook member into the first hook position in vertical alignment with the catch when the flip up lower seat cushion structural member is in the design seating position and a second actuator position wherein the actuator is lifted away from the hook stop and the hook member rotates into the second hook position out of vertical alignment with the catch to allow the flip up lower seat cushion structural member to be moved to the upright forward flipped position.

5. The seating assembly of claim 4 , wherein the hook stop of the inertia hook is disposed rearward of the hook member of the inertia hook.

6. The seating assembly of claim 1 , further comprising an opening in the structural member of the flip up lower seat cushion through which the hook member of the inertia hook extends vertically upward and wherein the cushion stop assembly is disposed proximate to the opening and the catch is in vertical alignment with the hook member when the inertia hook is rotated to the first hook position.

7. The seating assembly of claim 6 , wherein the opening is disposed proximate the rearward edge of the structural member of the flip up lower seat cushion and the catch comprises a tongue extending into the opening.

8. The seating assembly of claim 7 , wherein the cushion stop assembly includes a bracket having a pair of mounting ears disposed adjacent opposing sides of an outer perimeter of the opening and the tongue.

9. The seating assembly of claim 7 , wherein a distal end of the tongue is curved upwardly and a distal end of the hook member is curved downwardly whereby the distal end of the tongue and the distal end of the hook member are in vertical alignment and adapted to engage each other when the inertia hook is in the first hook position.

10. The seating assembly of claim 4 , wherein the seat frame further comprises a pair of mounting brackets disposed beneath the flip up lower seat cushion in the design seating position and on either side of the inertia hook to which the inertia hook is pivotally mounted.

11. The seating assembly of claim 10 , wherein the hook stop comprises a vertically and upwardly extending member disposed rearward of the inertia hook pivot and the hook member comprises a vertically and upwardly extending leg disposed forward of the inertia hook pivot and a horizontally and rearwardly extending leg having a distal end, whereby the distal end of the horizontally and rearwardly extending leg of the hook member is in vertical alignment and adapted to engage the catch when the inertia hook is in the first hook position.

12. The seating assembly of claim 11 , wherein the actuator comprises a lower surface disposed beneath the cushion stop assembly.

13. A seating assembly comprising;
a structural member pivotally anchored at a forward edge;
a catch and an actuator disposed proximate a rearward edge of the structural member; and
an inertia hook mounted to a stationary seat frame having a first position wherein the actuator urges a hook member into vertical alignment with the catch and a second position wherein the actuator is lifted and the hook member rotates out of vertical alignment with the catch.

14. The seating assembly of claim 13 , wherein a hook stop mounted to the inertia hook is disposed rearward of an inertia hook pivot supporting the inertia hook and a center of gravity of the inertia hook is disposed forward of the inertia hook pivot, and wherein the actuator is vertically disposed above and acts upon the hook stop to rotate the hook member into the first position in vertical alignment with the catch and the actuator is lifted away from the hook stop to rotate the hook member into the second position out of vertical alignment with the catch.

15. The seating assembly of claim 14 , wherein the structural member further comprises an opening through which the hook member extends vertically upward, the catch extends into the opening, and the catch is in vertical alignment with the hook member when the inertia hook is rotated to the first position.

16. The seating assembly of claim 15 , wherein the catch is disposed on a cushion stop bracket coupled with the structural member proximate the opening.

17. A seating assembly for a motor vehicle comprising;
a seat frame attached to a floor of the motor vehicle;
a flip up lower seat cushion structural member having a forward edge pivotally coupled with the motor vehicle and a rearward edge disposed proximate the seat frame;
a cushion stop assembly disposed on and proximate the rearward edge of the flip up lower seat cushion structural member, the cushion stop assembly having a catch and actuator; and
an inertia hook pivotally mounted to the seat frame by an inertia hook pivot, wherein the inertia hook has a hook stop disposed rearward of the inertia hook pivot and a center of gravity disposed forward of the inertia hook pivot, and wherein the actuator has a first position in contact with and acting upon the hook stop to rotate a hook member into vertical alignment with the catch and a second position wherein the actuator is lifted away from the hook stop to rotate the hook member out of vertical alignment with the catch.

18. The seating assembly of claim 17 , wherein the seat frame further comprises a pair of mounting brackets disposed beneath the flip up lower seat cushion structural member in a design seating position and on either side of the inertia hook to which the inertia hook is pivotally mounted.

19. The seating assembly of claim 17 , further comprising a pair of a flip up lower seat cushion structural members in side by side relation, each of the pair of flip up lower seat cushion structural members having a forward edge pivotally coupled with a floor of the moto
