TRACK LOCK MECHANISM

A position locking apparatus for a seat includes a track, a lock housing, a piston, a shaft, and a cam. The track has track teeth. The lock housing has a slot. The piston has piston teeth on a first distal end, which is configured to slide in the slot. The cam is attached to the shaft and the shaft pivotably couples with the lock housing. The cam is configured to contact a second distal end of the piston to press the piston towards the track such that the piston teeth engage with the track teeth to lock a position of the track relative to the piston and the lock housing in response to the cam being pivoted in a first angular direction via the shaft.
