ARMREST INERTIAL LATCH HAVING ANTI-REVERSE LOCK FOR ABSORBING DYNAMIC OSCILLATION DURING VEHICLE IMPACT

A vehicle seat assembly includes a seatback rotationally coupled to a base at a seat pivot. A securing pin is coupled with the seatback. An inertial latch is operable about a latch pivot to define an idle position defined by the inertial latch biased distal from the securing pin, and a deployed position defined by an opposing directional force biasing the inertial latch into selective engagement with the securing pin wherein the seatback is maintained in a predetermined rotational position. A guide latch is biased against the inertial latch and having an idle notch and a deployed notch. The idle notch selectively maintains the inertial latch in the idle position. The deployed notch secures the inertial latch in the deployed position in response to the opposing directional biasing force.
