Abstract

A vehicle seating assembly having a seat cushion and a suspension system disposed proximate an underside of the seat cushion. The suspension system includes a carrier assembly, a displaceable platform, and an attachment member extending between the carrier assembly and the displaceable platform, wherein the attachment member is positionable between the rest position and an extended positon. The displaceable platform is positionable between a design position and a fully deployed position.

First claim

What is claimed is:

1. A vehicle seating assembly comprising:
a seat cushion;
a suspension system disposed proximate an underside of the seat cushion and including:
a carrier assembly; and
a displaceable platform positionable between a design position and a fully deployed position and pivotably coupled to a front portion of the carrier assembly; and

an attachment member extending between the displaceable platform and a rear portion of the carrier assembly and including:
a link; and
a retraction mechanism comprising a core member and a housing, wherein the retraction mechanism is positionable between a rest position if the displaceable platform is in the design position and an extended position if the displaceable platform is in the fully deployed position, wherein the housing is fixedly coupled to the link and wherein the link is fixedly coupled to the displaceable platform, wherein the core member is fixedly coupled to the rear portion of the carrier assembly, wherein the housing is laterally movable along the core member as the retraction mechanism moves from the rest position to the extended position, wherein the housing surrounds the core member, wherein the housing includes a first housing part and a second housing part, wherein each of the first and second housing parts are pivotable about an axis that extends through the first and second housing parts, and wherein the first housing part and the second housing part pivot outward from the core member as the retraction mechanism moves from the rest position to the extended position.

2. The vehicle seating assembly of claim 1 , wherein the retraction mechanism includes an elastic band disposed around the first and second housing parts.

3. The vehicle seating assembly of claim 2 , wherein the core member includes a biasing mechanism configured to move the retraction mechanism from the extended position to the rest position after a sudden vehicle deceleration.

4. The vehicle seating assembly of claim 3 , wherein the biasing mechanism includes a coil spring disposed around the core member and configured to exert a force on a slidable ring disposed around the core member.

5. The vehicle seating assembly of claim 3 , wherein the link includes a T-shaped link.
