Abstract: A headrest for use on a motor-vehicle seat back has a base that is secured to the seat back, a head part, and respective base and head guides supporting the head part on the base for displacement in a direction between a rear rest position and a front extended position. A slide is provided between the base and the head part and is movable relative to both the head part and the base on shifting of the head part between the positions. A gear assembly engages both the head part and the base.

Abstract: A headrest assembly securable to a motor-vehicle seat back part has a movable headrest and a rod fixed in the seat back and having a plurality of vertically spaced catch formations. A spring carried on the headrest has a pair of legs flanking the rod, elastically deflectable toward and away from the rod, and biased elastically toward the rod, and a crosspiece connecting the legs and fittable with one of the catch formations. An actuator shiftable in the slide relative to the spring has respective actuating formations engageable with the spring legs. The actuator is movable between a latching position in which the actuating formations are generally disengaged from the respective legs and the crosspiece engages the rod and an unlatching position in which the actuating formations engage the respective legs and press them into the released position.

Abstract: A headrest has a generally vertical rod mountable in a motor-vehicle seat and formed with a plurality of vertically spaced and horizontally open notches, a support vertically movable along the rod and adapted to carry a head cushion, and a latch element vertically fixed on the support and shiftable on the support between a latched position engaged in one of the notches and locking the support on the rod against downward movement and an unlatched position disengaged from the rod and permitting free vertical movement of the support on the rod. An actuating element is pivotal about an axis on the support between an actuated position holding the latch element in the disengaged position and a rest position with the latch element in the engaged position.
