RETRACTABLE HEAD RESTRAINT FOR A VEHICLE SEAT

摘要

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.
