Abstract
A seat assembly includes a seat cushion frame, a seat back frame, a bracket, a pin actuator, a sensor, and an electronic control unit. The seat back frame is pivotally connected to the seat cushion frame about a pivot axis. The bracket is fixed to the seat cushion frame. The bracket includes a cam surface, and a distance between the cam surface and the pivot axis varies along the cam surface. The pin actuation includes a pin. The pin actuator is fixed to the seat back frame. The pin actuator is configured to move the pin from a disengaged position to an engaged position. The electronic control unit determines whether the sensor detects the front collision of the vehicle and controls the pin actuator to move the pin from the disengaged position to the engaged position.
