ABSTRACT:
An automotive seat assembly having a J-lock safety device which interlocks a rear seat entry track mechanism during high load situations. The entry track mechanism comprises a lower track and an upper track movably supported by the lower track for providing fore and aft movement of the seat assembly along a longitudinal axis. A downwardly facing first hook is attached to the lower track and has a J-shape with a long leg and a short leg interconnected by a bottom. An upwardly facing second hook is attached to the upper track and has a J-shape with a long leg and a short leg interconnected by a bottom. The short legs are in mechanically overlapping relationship for limiting relative movement of the tracks in a direction transverse to the longitudinal axis. The bottom of the first hook includes a plurality of apertures and a plurality of teeth extend upwardly from the short leg of the second hook, such that the teeth of the short leg of the second hook engage the apertures of the bottom of the first hook in response to impact forces urging the tracks in the direction transverse to the longitudinal axis.
