Adjustable vehicle head restraint assembly for a vehicle seat
First Claim
1. A vehicle head restraint system for a vehicle seat comprising:
- a support rod adapted to be mounted to a vehicle proximate to the vehicle seat, the support rod having a lateral portion;
a head restraint moveable relative to the lateral portion in a fore/aft direction;
a first locking plate movably mounted to the head restraint to engage the support rod to lock the head restraint relative to the support rod in one of an intermediate position and an extended position;
a second locking plate movably mounted to the head restraint to engage the support rod to lock the head restraint relative to the support rod in one of the intermediate position and the extended position;
a rotary link pivotally connected to the head restraint and interconnecting the first locking plate and the second locking plate;
a biasing member mounted between the support rod and at least one of the first locking plate and the second locking plate to bias the head restraint towards a retracted position; and
an actuator provided on the head restraint to move one of the first locking plate and the second locking plate such that the rotary link moves the other of the first locking plate and the second locking plate for disengaging the first and second locking plates from the support rod so that the biasing member biases the head restraint towards the retracted position.

Abstract
A vehicle head restraint system for a vehicle seat has a support rod with a lateral portion. A head restraint is moveable relative to the lateral portion in a fore/aft direction. A first locking plate and a second locking plate are each moveably mounted to the head restraint to engage the support rod to lock the head restraint relative to the support rod. A rotary link is pivotally connected to the head restraint and interconnects the first and second locking plates. A biasing member is mounted to at least one of the first and second locking plates to bias the head restraint towards a retracted position. An actuator on the head restraint moves one of the first and second locking plates. The rotary link moves the other of the first and second locking plates for disengaging the first and second locking plates from the support rod.

16. A vehicle seat comprising:
-
a seat back adapted to be pivotally mounted within a vehicle; a support rod mounted to the seat back, the support rod having a lateral portion; a head restraint moveable relative to the lateral portion in a fore/aft direction; a first locking plate movably mounted to the head restraint to engage the support rod to lock the head restraint relative to the support rod in one of an intermediate position and an extended position; a second locking plate movably mounted to the head restraint to engage the support rod to lock the head restraint relative to the support rod in one of the intermediate position and the extended position; a rotary link pivotally connected to the head restraint and interconnecting the first locking plate and the second locking plate; a biasing member mounted between the support rod and at least one of the first locking plate and the second locking plate to bias the head restraint towards a retracted position; and an actuator provided on the head restraint to move one of the first locking plate and the second locking plate such that the rotary link moves the other of the first locking plate and the second locking plate for disengaging the first and second locking plates from the support rod so that the biasing member biases the head restraint towards the retracted position. - View Dependent Claims (17, 18, 19)

20. A vehicle head restraint system for a vehicle seat comprising:
-
a support rod adapted to be mounted to a vehicle proximate to the vehicle seat, the support rod having a lateral portion and having a first locking tab and a second locking tab; a head restraint moveable relative to the lateral portion in a fore/aft direction, the head restraint having a first guide member and a second guide member formed therein; a first locking plate movably mounted to the head restraint and having a plurality of notches formed therein for engaging the first locking tab to lock the head restraint relative to the support rod in one of an intermediate position and an extended position, the first locking plate having an aperture formed therein to receive the first guide member; a second locking plate movably mounted to the head restraint and having a plurality of notches formed therein for engaging the second locking tab to lock the head restraint relative to the support rod in one of the intermediate position and the extended position, the second locking plate having an aperture formed therein sized to receive the .second guide member; a rotary link pivotally connected to the head restraint and interconnecting the first locking plate and the second locking plate; a first biasing member mounted between the support rod and at least one of the first locking plate and the second locking plate to bias the head restraint towards a retracted position; and an actuator provided on the head restraint to move one of the first locking plate and the second locking plate such that the rotary link moves the other of the first locking plate and the second locking plate for disengaging the first and second locking plates from the first and second locking tabs so that the biasing member biases the head restraint towards the retracted position.
