Abstract: 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.

Abstract: An air bag device in which an internal acceleration sensor is prevented from operating a main body of an air bag device is mounted on a vehicle. The device is provided with a stopper for interlinking a fixing bolt for mounting the main body of the air bag device on the vehicle with a canceling screw for canceling the state of preventing the actuation of the acceleration sensor. Before the main body of the air bag device is threadingly inserted into the vehicle by means of the fixing screw and is thereby secure, the stopper keeps the canceling screw from being threadingly inserted.

Abstract: A mechanism for mounting an air bag assembly on a steering wheel. Before the air bag assembly is firmly screwed to the steering wheel, claws projecting from the air bag assembly engage with claws of the steering wheel so as to temporarily fix the air bag assembly to the steering wheel. Subsequently, the air bag assembly is screwed to the steering wheel, and the air bag assembly does not move inadvertently without being manually pressed firmly at the time of screwing, thereby rendering the mounting operation speedy and accurate.

Abstract: The present invention relates to a mounting apparatus for a steering wheel pad of a motorcar. The pad is adapted to be detachably mounted on a lower cover member by cooperating snap members and retainer members. The engagement of the pad is ensured during the mounting operation so that the pad may be easily slid into position. The necessity of a connector connection of the horn switch before the engagement of the pad is not present since the horn button is positioned to engage a fixed contact on the retainer. The engagement and disengagement of the pad are simplified and a more accurate and positive mounting operation may be effected.
