RETRACTABLE HEAD RESTRAINT FOR A VEHICLE SEAT
First Claim
1. A vehicle seat comprising:
- a bracket adapted to be mounted to a vehicle body;
a seat back frame pivotally connected to the bracket for movement between an upright position and a collapsed position;
a head restraint mounted to the seat back frame to translate relative to the seat back frame; and
a transmission connected to the bracket, the seat back frame and the head restraint to provide a geared engagement between the head restraint and the bracket such that translation of the head restraint relative to the seat back frame is a direct relationship of a pivotal position of the seat back frame relative to the bracket in order to extend the head restraint when the seat back frame is at the upright position and to retract the head restraint when the seat back frame is in the collapsed position.

Abstract
A vehicle seat includes a bracket for mounting to a vehicle body. A seat back frame is pivotally connected to the bracket for movement between an upright position and a collapsed position. A head restraint is mounted to the seat back frame to translate relative to the frame. A transmission is connected to the bracket, the frame and the head restraint to provide a geared engagement between the head restraint and the bracket such that translation of the head restraint relative to the seat back frame is a direct relationship of a pivotal position of the seat back frame relative to the bracket in order to extend the head restraint at the upright position and to retract the head restraint in the collapsed position.

19. A vehicle seat comprising:
-
a bracket adapted to be mounted to a vehicle body; a sector gear mounted to the bracket; a seat back frame pivotally connected to the bracket for movement between an upright position and a collapsed position; an input gear mounted for rotation to the seat back frame in engagement with the sector gear such that pivoting of the seat back frame relative to the bracket causes the input gear to rotate as it travels along the sector gear; an output gear driven by the input gear; a toothed belt connected to the output gear; an idler gear mounted for rotation to the seat back frame in engagement with the toothed belt for keeping the toothed belt under tension; and a head restraint mounted to the toothed belt and cooperating with the seat back frame to translate relative to the seat back frame such that translation of the head restraint relative to the seat back frame is a direct relationship of a pivotal position of the seat back frame relative to the bracket in order to extend the head restraint when the seat back frame is at the upright position and to retract the head restraint when the seat back frame is in the collapsed position. - View Dependent Claims (20)
