Air bag device

摘要

An air bag device is equipped with a restricting member for preventing an air bag accommodated in an air bag main body from being inflated erroneously upon impact before the air bag main body is attached to a body of a vehicle inclusive of a steering wheel. This restricting member, only when a deactivating member for deactivating the operation of an acceleration sensor is in operation, allows the air bag main body to approach a designated attaching area of the body of a vehicle. After the air bag main body is secured, the operation of the deactivating member is released to the put the acceleration sensor in an operation activating condition.
