1. An air bag apparatus for inflating an air bag of an air bag body when an acceleration exceeding a predetermined value has acted on said air bag body, comprising:
- mechanically movable locking means for preventing said air bag from being inflated when said acceleration on said air bag body exceeds said predetermined value;
mounting means for mounting said air bag body on a chassis; and
unlocking means having an actuating member which is pushed into said air bag body by an operation of an operator for releasing said locking means, and a stopper for preventing the movement of said actuating member in an opposite direction after being pushed in, for canceling the actuation of said locking means by an operation after the mounting of said air bag body on said chassis by said mounting means and permitting subsequently the inflation of said bag when said acceleration on said air bag body exceeds said predetermined value,whereby the inflation of said air bag is prevented prior to the mounting of said air bag body on said chassis and after the mounting of said air bag body on said chassis until said operation is performed.

Abstract
An air bag apparatus is disclosed having a locking device which is adapted to prevent the inflation of a bag accommodated in an air bag body before the air bag body is mounted on a chassis, the bag being adapted to be inflated in front of a seat occupant when a predetermined acceleration has acted on the air bag body. This locking device is arranged such that an actuating member is driven by an operator'"'"'s operation after mounting the air bag body on the chassis to release the locking device, thereby canceling a locked state and making the air bag body operable.

11. An air bag apparatus having locking means for preventing a bag accommodated in an air bag body from inflating prior to mounting said air bag body which is mounted on a steering wheel, comprising:
-
an actuating member having one end disposed in the vicinity of an axis of a steering wheel and the other end disposed in the radial direction of said steering wheel, said other end being adapted to move longitudinally upon application thereto of an operating force exerted by an operator; a release pin disposed in the axial direction of said steering wheel or parallel therewith and adapted to unlock said locking means through axial movement of said release pin and to set said air bag body in an operable state at the time when an acceleration has acted on said air bag body; and conversion means for converting a longitudinally moving force of said actuating member into an axially moving force of said release pin whereby an operating force to said actuating member is imparted to said release pin via said converting means after mounting said air bag body on said steering wheel, thereby permitting the operation of said air bag body. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. An air bag apparatus for inflating a bag accommodated in an air bag body when an acceleration exceeding a predetermined value has acted on said air bag body, comprising:
-
locking means for preventing said bag from being inflated when said acceleration exceeding said predetermined value has acted on said air bag body; mounting means for mounting said air bag body on a chassis; and a flexible actuating member having one end corresponding to said locking means, a bent intermediate portion, and the other end led in a direction moving away from the axis of a steering wheel and serves an inputting portion for inputting an operating force of an operator, said locking means being unlocked by a longitudinally operating force exerted by the operator. - View Dependent Claims (19, 20, 21)

22. An air bag apparatus for inflating an air bag of an air bag body when an acceleration exceeding a predetermined value has acted on said air bag body, comprising:
-
mechanically movable locking means for preventing said air bag from being inflated when said acceleration on said air bag body exceeds said predetermined value; mounting means for mounting said air bag body on a chassis; unlocking means having an actuating member for releasing said locking means, and for canceling the actuation of said locking means by an operation after the mounting of said air bag body on said chassis by said mounting means and permitting subsequently the inflation of said bag when said acceleration on said air bag body exceeds said predetermined value; and a thread member provided on said actuating member having threads to enable said thread member to be screwed so as to push said actuating member for unlocking said locking means, whereby the inflation of said air bag is prevented prior to the mounting of said air bag body on said chassis and after the mounting of said air bag body on said chassis until said operation is performed.
