Claims

[Claims for Utility Model Registration] A mass body that detects sudden deceleration of a vehicle through inertial movement; an ignition pin that acts on the detonator to expand the bag; and an ignition pin that engages with the ignition pin to prevent movement of the ignition pin, and rotates with the drive shaft to move the ignition pin when the vehicle suddenly decelerates. a trigger member for releasing the blocking;
An airbag starting device comprising: a pressing member that presses a drive shaft in a direction opposite to a direction in which the trigger member releases the prevention of movement of the ignition pin when the vehicle suddenly decelerates, the trigger member of the ignition pin; An air bag starting device characterized in that the engaging surface is formed into a conical or spherical surface and is brought into point contact with the trigger member.
