Retractable pop-up head rest usable with a vehicle passenger seat
First Claim
1. A retractable pop-up head rest assembly for use with a vehicle passenger seat comprising:
- a head rest mounted for vertical movement from a normally retracted position adjacent the seat to an extended operative position;
the vertical movement provided by an elongated shaft 26 slidable relative to an elongated hollow outer shell and carrying said head rest and movable therewith, said shaft being mounted for rocking movement within a gap formed in the seat;
biasing means mounted below said head rest for resiliently urging said head rest to move vertically from said retracted position towards said extended operative position;
vertical restraining means mounted below said head rest for restraining the vertical upward movement of said shaft from said retracted position;
said shaft being rockably movable between a first position where said vertical restraining means restrains said shaft from upward vertical movement and a second position where said shaft is caused to move vertically upwardly by said biasing means;
horizontal restraining means mounted below said head rest for restraining the rocking movement of said shaft from said first position to said second position and operable in response to a predetermined amount of force being exerted thereon caused by the rapid deceleration of the vehicle so as to permit said shaft to rock from said first position to said second position thereby causing said biasing means to urge said shaft from said retracted position towards said operative position.

Abstract
A retractable pop-up head rest assembly is provided which is usable with a vehicle passenger seat. A head rest is mounted for vertical movement from a normally retracted position adjacent the seat to an extended operative position. The vertical movement of the head rest is provided by an elongated shaft which slidable relative to the seat and carries the head rest and is movable therewith. The shaft is mounted for rocking movement by a gap formed in the seat. The spring is mounted below the head rest for resiliently urging the head rest to move vertically from the retracted position towards the extended operative position. A trigger member is mounted below the head rest for restraining the vertical upward movement of the shaft from the retracted position. The shaft is rockably movable between a first position and a second position. The trigger member also restrains the rocking movement of the shaft from the first position to the second position and is operable in response to a predetermined amount force being exerted thereon caused by the rapid deceleration of the vehicle so as to permit the shaft to rock from the first position to the second position thereby causing the spring to urge the shaft from the retracted position towards the operative position.
