PIVOTING HEADREST FOR USE IN A REAR ROW SEAT AND INCORPORATING TRIGGER RELEASE WITH CABLE SLACK PICKUP DURING SEATBACK ROTATION TO A FORWARD DUMP POSITION

A pivoting headrest assembly incorporated into a rear row vehicle seat including a base and a pivotally supported seatback. A first bracket is fixedly supported atop the seatback and exhibits a striker. A second bracket is pivotally supported to the first bracket in a biased direction away from the striker and includes a headrest bun support. A hook is supported upon the second bracket in a first biased direction engaging the striker. A release element associated with the second bracket is biased direction and which, upon being actuated in a second counter-biased direction, engages a projecting portion associated with the hook. A cable is secured at a first end to a fixed location associated with the seat and extends through a redirection location an offset distance from a pivot location of the seatback, the cable securing at a second end to the release element. Upon the seatback being pivoted relative to the fixed location, translation of the cable around the redirection location results in actuation of the release element to separate the hook from the striker and the second bracket to pivot away from the first bracket. A return bias of the release element results in take-up of slack in the cable, concurrent with return pivoting of the second bracket into engagement with the striker.
