Air bag device
First Claim
1. An air bag device mounted on a vehicle and having a bag adapted to be inflated in front of an occupant of a vehicle upon actuation of an acceleration sensor, said air bag device comprising:
- a main body having said bag and said acceleration sensor;
mounting means for mounting said main body onto the vehicle;
preventing means for preventing the actuation of said acceleration sensor;
prevention canceling means for canceling the preventing action of said preventing means and adapted to be operated during assembly; and
restraining means for rendering said prevention canceling means operable after said main body is mounted on said vehicle by said mounting means,whereby the operation of said acceleration sensor is prevented by an impact applied to said air bag body during the mounting of said air bag body onto said vehicle.

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.

-
a main body having said bag and said acceleration sensor; mounting means for mounting said main body onto the vehicle; preventing means for preventing the actuation of said acceleration sensor; prevention canceling means for canceling the preventing action of said preventing means and adapted to be operated during assembly; and restraining means for rendering said prevention canceling means operable after said main body is mounted on said vehicle by said mounting means, whereby the operation of said acceleration sensor is prevented by an impact applied to said air bag body during the mounting of said air bag body onto said vehicle. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. An air bag device for a vehicle, comprising:
-
an main body incorporating a bag and means for inflating said bag; mounting means for securing said main body onto the vehicle; a canceling screw which can be threadingly inserted in parallel with said mounting means, said canceling screw, when threadingly inserted, being capable of operating said inflating means inside said main body at a predetermined acceleration; and restraining means which is rotatable about said canceling screw and is movable in it axial direction after said main body is secured to said chassis by said mounting means, thereby allowing said canceling screw to be threadingly inserted. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. An air bag device in which an acceleration sensor is provided in an main body, a gas is supplied to a bag upon actuation of said acceleration sensor so as to inflate said bag in front of a driver of a vehicle, said air bag device comprising:
-
preventing means disposed in said air bag body and adapted to prevent the operation of said main body even if an acceleration has occurred; a fixing screw for fixing said main body onto a steering wheel of said vehicle; a canceling screw which is supported by said main body coaxially with said fixing screw and is adapted to cancel the actuation of said preventing means by being threadingly inserted so as to render said bag inflatable by the action of an acceleration; and a stopper which is rotatable about an axis of said canceling screw, but abuts against an enlarged-diameter portion of said canceling screw, and prevents the threading insertion of said canceling screw as said stopper abuts against a head of said fixing screw before the threading insertion of said fixing screw. - View Dependent Claims (19, 20)
