Abstract
A seat track assembly includes a lock having a lock pin movable between locking and unlocking positions. A guide forms a cylinder supporting movement of the lock pin and first and second shear plates are located on opposite sides of the guide. A spring member resiliently biases the lock pin toward the locking position. The lock pin extends through openings in the first and second shear plates. The lock pin, the guide, and the spring member are located entirely within an interior space of a movable track. A release assembly includes a bracket secured to the movable track, a pivotable fork, and a handle pivotally attached to the bracket and operably engaging the fork so that pivotable movement of the handle pivots the fork to move the lock pin. A secondary spring member biases the release assembly toward the locking position.
