ADJUSTABLE HEAD RESTRAINT ASSEMBLY FOR VEHICLE SEATS
First Claim
1. An adjustable vehicle head restraint assembly comprising:
- at least one post adapted to be mounted in a vehicle proximate to a seat back;
a transverse shaft mounted to the at least one post;
a head restraint pivotally connected to the transverse shaft;
a series of teeth provided on the head restraint;
a locking mechanism mounted to the transverse shaft for translation in a transverse direction for engagement with the series of teeth; and
an actuator mounted to the head restraint in cooperation with the locking mechanism such that actuation of the actuator in the transverse direction disengages the locking mechanism from the series of teeth for permitting adjustment of a tilt of the head restraint relative to the transverse shaft.

Abstract
An adjustable vehicle head restraint assembly is provided with a post mounted in a vehicle proximate to a seat back. A transverse shaft is mounted to the post. A head restraint is pivotally connected to the shaft. A series of teeth are provided on the head restraint. A locking mechanism is mounted to the shaft for translation in a transverse direction for engagement with the teeth. An actuator cooperates with the locking mechanism for disengaging the mechanism from the series of teeth for permitting adjustment of a tilt of the head restraint. A head restraint assembly is provided with a partial ring gear mounted to the head restraint. A sector gear is mounted to a transverse shaft in engagement with the partial ring gear. The actuator translates one of the partial ring gear and the sector gear for disengaging the gears and permitting adjustment of the tilt.

18. An adjustable vehicle head restraint assembly comprising:
-
at least one post adapted to be mounted in a vehicle proximate to a seat back; a transverse shaft mounted to the at least one post; a head restraint pivotally connected to the transverse shaft; a series of teeth provided on the head restraint extending radially toward the transverse shaft; a locking mechanism mounted to the transverse shaft for converting translation in a transverse direction to translation in a direction perpendicular to the transverse direction for engagement with the series teeth; and an actuator mounted to the head restraint in cooperation with the locking mechanism such that actuation of the actuator in the transverse direction disengages the locking mechanism from the series of teeth for permitting adjustment of a tilt of the head restraint relative to the transverse shaft. - View Dependent Claims (19, 20)
