Abstract

See full text

A head restraint assembly having a bushing member adapted for retaining and guiding a post supporting the head restraint pad of a motor vehicle seat back. The bushing is installed within the seat back and allows the head restraint pad to be positioned at various vertical positions to suit individual seat occupants. The head restraint post has a plurality of detent notches and a retainer notch. The bushing includes a detent lug engagable with the notches such that various indexed positions of the head restraint pad are provided. The detent notches of the post have ramped cam surfaces enabling the pad to be moved between the detent positions by exerting axial loads on the post. The retainer notch engages the lug to prevent inadvertent withdrawal of the head restraint pad. Complete withdrawal, however, is provided by an actuator mechanism which urges the lug to withdraw it from engagement with the post retainer notch. The release actuator includes a leaf spring element, having an end which can be depressed downwardly to exert an outward biasing force on the detent lug, causing the lug to be disengaged from the retainer notch enabling the head restraint post to be withdrawn from the head restraint.
