The present disclosure provides an occupant protection system protecting an occupant in a vehicle by a protection device provided in the vehicle the occupant protection system having a gas generator, a prediction unit, and a control unit.

An airbag is a passenger seat airbag that inflates and deploys between a passenger seat and an instrument panel, and has side vent holes and a front vent hole. When an inflator is actuated in a state where a passenger close to the instrument panel exists, a valve cloth opens the front vent hole with the vicinity of the front vent hole away from the windshield.

A control device of an electromagnetic actuator for a restraint device, including an evaluation and control unit which generates a control signal which predefines a control sequence having control time periods, in which the actuator is activated, and pause time periods, in which the actuator is deactivated. A protective circuit including a counter is provided, the counter monitoring the control sequence and increments its counter content during the at least one control time period and decrements its counter content during the at least one pause time period, the protective circuit effectuating a deactivation of the actuator when the counter content reaches or exceeds a predefined first threshold value, and allows a reactivation of the actuator when the counter content reaches or falls below a predefined second threshold value after reaching or exceeding the first threshold value, the first counter content being greater than the second counter content.
