Abstract

PURPOSE:To prevent an erroneous operation at the time of assembling by rotatably providing a set pin as a safety device on the front end part of an operating impulse needle which is energized by springs, forming cut-outs and a groove part on the pin, and prohibiting and holding the movement of the impulse needle and the rotation of weights at the time of operating the safety device. CONSTITUTION:When a deceleration above a defined value (collision) occurred on a vehicle, the sudden deceleration is detected and the ignition of explosives is carried out to perform the stretching operation of a seat belt and the rapid expansion of an air bag. An operating impulse needle 23 is energized by springs 24, 26 and slidably inserted in the guide hole 22 of a sensor body 20, and a set pin 42 and a shutter member 51 as a safety device are provided on the front end part thereof. Cut-out parts 44, 45 and a groove 46 are formed on the set pin 42 to prohibit the movement of the impulse needle 23 and the rotation of weights 21 at the time of operating the safety device. However, such actions can be carried out after the safety device is released. Thereby, when the safety device is operated at the time of assembling, etc., the erroneous operation of igniting explosives due to the operation of the impulse needle and the weights can be securely prevented.
