An inflatable safety bag system for vehicles which comprises an electrical actuator device for detecting a vehicle collision, a mechanical actuator device for detecting a vehicle collision, and a valve opening device for a high-pressure gas container for supplying high-pressure gas to a safety bag at the time of a vehicle collision. The electrical and mechanical actuator devices are operatively connected to the valve opening device, and are actuatable independently of each other. The valve opening operation of the high-pressure gas container is effected in response to actuation of at least one of the electrical and mechanical actuator devices. When the electrical actuator device fails to operate, the mechanical actuator device enables the safety bag to be inflated, thereby ensuring positive and reliable operation of the safety bag system.
