An apparatus is provided for securing a moveable scat substructure of a vehicle seating system to a stationary base substructure of the vehicle seating system during a dynamic event such as, for example, rapid vehicle deceleration. In one embodiment, an inertia lock apparatus is provided for a vehicle seating system and includes: a striker bar; a pendulum latch pivotally moveable between a normal orientation and a latching orientation; and a lock mechanism configured to prevent the pendulum latch from moving from the latching orientation to the normal orientation. In another embodiment the inertia lock apparatus includes a release mechanism for moving the pendulum latch from the latching orientation to the normal orientation, thereby unlocking the lock mechanism and resetting the apparatus. In another aspect, a vehicle seating system including the inertia lock apparatus is provided.
