Abstract

A vehicle seating assembly having a seat base and a seat back. Bolsters extend laterally from one of the seat base and the seat back and include a bolster support having a hinge assembly and an abutment member and a substantially planar engagement surface disposed therebetween. A flexible cushion overlies the bolster support. A spring-biased dynamic member is operably coupled with one of the seat back and the seat base and is slidably engaged with the substantially planar engagement surface. The spring-biased dynamic member is operable between articulated and unarticulated positions. The spring-biased dynamic member moves to the articulated position upon initiation of a user-initiated event.

Claims

1. A vehicle seating assembly comprising:

a seat base and a seat back;

bolsters extending laterally from one of the seat base and the seat back and including;

a bolster support having an abutment member and a substantially planar engagement surface adjacent thereto;

a flexible cushion overlying the bolster support;

a dynamic member operably coupled with one of the seat back and the seat base and slidably engaged with the substantially planar engagement surface, the dynamic member being operable between articulated and unarticulated positions; and

an arm rigidly coupled with the dynamic member;

a pivot bar disposed between the arm and the dynamic member;

a spring assembly operably coupled with the arm and biasing the arm to rotate the dynamic member to the unarticulated position.

2. The vehicle seating assembly of claim 1, further comprising:

a vehicle door operably coupled to the bolsters, wherein the dynamic member is also moveable to the unarticulated position when the vehicle door is opened and the articulated position when the vehicle door is closed.

3. The vehicle seating assembly of claim 1, wherein the dynamic member also moves to the articulated position when a load of at least 80 pounds (36.3 kg) is positioned on the seat base.

4. The vehicle seating assembly of claim 1, wherein the dynamic member is moveable to the articulated position when the seat base is occupied and the unarticulated position when the seat base is unoccupied.

5. The vehicle seating assembly of claim 1, further comprising:

an underlying seat structure, wherein the dynamic member is spring-biased by a torsion spring operably coupled between a proximal end of the dynamic member and the underlying seat structure.

6. The vehicle seating assembly of claim 1, further comprising:

an underlying seat structure, wherein the dynamic member is spring-biased by a tension spring operably coupled between a proximal end of the dynamic member and the underlying seat structure.

7. A vehicle seating assembly comprising:

a bolster support having a flexible cushion disposed thereon;

a dynamic member slidably engaged with the bolster support and operably coupled with a load arm, the dynamic member and load arm being pivotable about a pivot member disposed therebetween; and

a spring member engaged with the load arm to bias the load arm, dynamic member, and bolster support to an unarticulated position.

8. The vehicle seating assembly of claim 7, further comprising:

a vehicle door operably coupled to the bolsters, wherein the dynamic member is also moveable to the unarticulated position when the vehicle door is opened and the articulated position when the vehicle door is closed.

9. The vehicle seating assembly of claim 7, wherein the dynamic member moves to an articulated position when the load is at least 80 pounds (36.3 kg).

10. The vehicle seating assembly of claim 7, wherein the dynamic member is moveable to the articulated position when the seat base is occupied by a passenger and the unarticulated position when the seat base is unoccupied by a passenger.

11. The vehicle seating assembly of claim 7, wherein the bolster support and the dynamic member define a spacer gap.

12. The vehicle seating assembly of claim 7, wherein a planar extent of the dynamic member and a planar extent of the load arm define an acute angle.

13. The vehicle seating assembly of claim 7, wherein the bolster support includes an abutment member configured to abut a distal end of the dynamic member.

14. A vehicle seating assembly comprising:

a vehicle door configured to be opened and closed;

cushioned bolsters extending from the vehicle seating assembly and including;

a bolster support;

a dynamic member rotatable about a pivot pin and rigidly coupled with a spring-biased load arm, the dynamic member being moveable to an unarticulated position when the vehicle door is opened and an articulated position against the spring-bias of the load arm when the vehicle door is closed.

15. The vehicle seating assembly of claim 14, further comprising:

an underlying seat structure supporting the seat base, wherein the load arm is spring-biased by a torsion spring operably coupled between the load arm and the underlying seat structure.

16. The vehicle seating assembly of claim 14 comprising:

an underlying seat structure supporting the base, wherein the load arm is spring-biased by a compression spring operably coupled between the load arm and the underlying seat structure.

17. The vehicle seating assembly of claim 14, wherein the bolster support and the dynamic member define a spacer gap.

18. The vehicle seating assembly of claim 14, wherein the bolster support includes an abutment member configured to abut a distal end of the dynamic member.

19. The vehicle seating assembly of claim 14, wherein the dynamic member is also moveable to the articulated position when the seat base receives a predetermined load and moveable to the unarticulated position when the seat base is absent a predetermined load.
