Abstract
An inertial latch system includes a floor bracket, a seat cushion bracket, an inertial weight and an inertial weight damper assembly. The seat cushion bracket is rotatable between a down position, an up position and an intermediate position between the down and up positions. The inertial weight damper assembly is selectively coupled to the inertial weight and includes a detent plunger and a contact plug coupled to the detent plunger. The detent plunger is movable between an extended condition and a retracted condition. In each of the up and down positions, the detent plunger is in the extended condition and inhibits movement of the seat cushion bracket from the up and down positions, respectively, and the contact plug inhibits movement of the inertial weight. In the intermediate position, the detent plunger is in the retracted condition, and the contact plug does not inhibit movement of the inertial weight.
