ABSTRACT:
A vehicle seat track assembly includes an elongated fixed track structure constructed and arranged to be fixed to a vehicle floor and a movable track structure cooperable with the fixed track structure. A plurality of rolling elements are engaged between track structures for rollingly supporting the movable track structure on the fixed track structure to enable the movable track structure to be moved in opposite directions through a range of adjusting movements with respect to the fixed track structure. An adjusting mechanism IS operatively associated with the track structures and is constructed and arranged to permit the movable track structure to be moved through the adjusting movements. The adjusting mechanism includes a locking and releasing device constructed and arranged to be moved between (1) a locking position preventing the adjusting movements from being affected and (2) a releasing position wherein the locking and releasing device is operable to release the adjusting mechanism to permit the adjusting movements. A lock and release system is operatively associated with the track structures and includes locking structure movable between a released position permitting the adjusting movements and a locked position preventing the adjusting movements from being affected. The lock and release system includes shock responsive structure constructed and arranged to move the locking structure to the locked position thereof in response to a crash condition which occurs while the locking and releasing device is in the releasing position thereof.
