Abstract
An inertia locking system for a seat of a vehicle includes a base member that is fixed to a seat structure and a Double D shaped shaft that rotates with a cam to allow the seat back to be adjusted. A movable inertia locking bracket has an opening including a circular portion and a slot portion. The Double D shaped shaft is disposed in the opening of the inertia locking bracket and includes flat opposite surfaces that prevent rotation of the Double D shaped shaft relative to the inertia bracket when the Double D shaped shaft is disposed in the slot portion of the opening. Acceleration causes the inertia locking bracket to slide forward such that the Double D shaped shaft is disposed in the elongate slot portion to prevent rotation of the Double D shaped shaft and prevent release of the seat back mechanism.
