Adjustable seat bolster for easy access
First Claim
1. An ergonomic device for a vehicle seat comprising:
- a pressure surface oriented toward a seat cushion such that said pressure surface deploys to support a seat occupant;
a mounting bracket adapted to be connected to a frame of the vehicle seat;
a linkage between said pressure surface and said mounting bracket such that said pressure surface is selectively positionable between a first position disposed to extend for support of a seat occupant and a second position that is retracted;
a power actuator in operative communication with said linkage such that said power actuator mediates travel of said pressure surface between said first and second position;
said power actuator being in operative communication with a use anticipation indicator such that said power actuator is engaged to place said pressure surface in said second, retracted position upon a signal from said use anticipation indicator; and
characterized in that said linkage includes a bolster wire and slider mechanism.

Abstract
An ergonomic device (10, 110) for a vehicle seat includes a pressure surface (106, 206) oriented toward a seat cushion so that the pressure surface deploys to support a seat occupant. A mount bracket (102,202) fixes the device to a frame of the automobile seat. A linkage (112, 144, 166) between the pressure surface and said mount bracket allows the pressure surface to be selectively positionable between a first position disposed to extend for support of a seat occupant and a second position that is retracted. A power actuator (20, 130) is in operative communication with the linkage such that the power actuator mediates travel of the pressure surface between the first and second positions. The power actuator (20, 130) is in communication with a use anticipation indicator (40) such that the power actuator is engaged to place the pressure surface in the second, retracted position upon a signal from the use anticipation indicator.

21. A method of controlling extension and retraction of an ergonomic bolster device for a vehicle seat comprising:
-
orienting a pressure surface proximate to a seat cushion such that the pressure surface may deploy to support a seat occupant; mounting by a bracket the pressure surface onto a frame of the vehicle seat; linking the pressure surface to the mounting bracket such that the pressure surface is selectively positionable between a first position deployed to extend for support of a seat occupant and a second position that is retracted; engaging a power actuator in operative communication with the linkage such that the power actuator mediates travel of the pressure surface between the first position and the second position; connecting the power actuator to a communicator with a use anticipation indicator such that the power actuator is engaged to place the pressure surface in the second, retracted position upon a first signal from the use anticipation indicator; and characterized by using a linkage including a bolster wire and slider mechanism. - View Dependent Claims (22)
