Adjustable Seat Cushion Bolster Mechanism
First Claim
1. A seat frame assembly for compactly folding a motor vehicle seat, said seat frame assembly comprising:
- at least one side frame member;
an actuator operatively coupled to said side frame member;
an elongated control arm having a first end pivotally coupled to said side frame member and an opposite distal end;
a control link having one end pivotally coupled to said side frame member and an opposing end operatively coupled to said distal end of said control arm; and
a seat cushion linkage assembly operably coupled between one of said control arm and control link and said actuator for moving each of said control arm and control link between a stowed position generally parallel with and adjacent to said side frame member and a support position spaced from said side frame member in response to actuation of said actuator.

Abstract
A seat frame assembly is provided for compactly folding a motor vehicle seat. The seat frame assembly includes at least one side frame member. An actuator is operatively coupled to the side frame member. An elongated control arm includes a first end pivotally coupled to the side frame member and an opposite distal end. A control link includes one end pivotally coupled to the side frame member and an opposing end operatively coupled to the distal end of the control arm. A seat cushion linkage assembly is operably coupled between one of the control arm and control link and the actuator for moving each of the control arm and control link between a stowed position generally parallel with and adjacent to the side frame member and a support position spaced from the side frame member in response to actuation of the actuator.

10. A motor vehicle seat comprising:
-
a seat cushion having at least one side frame member;
a first control arm pivotally coupled to said side frame member of said seat cushion for movement between a support position and a stowed position;
a seat back pivotally coupled to said seat cushion and having at least one side frame member;
a second control arm pivotally coupled to said side frame member of said seat back for movement between a support position and a stowed position;
an actuator operably coupled to said first control arm for moving said first control arm between said support and stowed positions; and
a cable assembly operably connected between said first control arm and said second control arm for urging said second control arm between said support and stowed positions as said actuator moves said first control arm between said respective support and stowed positions to selectively allow compact folding of said seat back against said seat cushion. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method of adjusting the shape of a side bolster portion, having a control arm pivotally secured to a side frame member for movement between a stowed position and a support position, independent of a center seating portion of a seat, the method comprising the steps of:
-
defining the side bolster portion independent of the center seating portion;
actuating the control arm between the support position and stowed position; and
altering the shape of the side bolster portion relative to the shape of the center seating portion in response to actuation of the control arm between the support and stowed positions. - View Dependent Claims (18, 19)
