ABSTRACT:
A deactivating device for a locking mechanism of a pretensioner. The deactivating device includes: an operation lever provided movably about a central axis of rotation and in a direction of the central axis of rotation, and adapted to set the locking mechanism in one of an activated state and a deactivated state; and an urging member for imparting an urging force to the operation lever, wherein the operation lever has a deactivation operation mode for setting the locking mechanism in the deactivated state as the operation lever moves continuously in stages about the central axis of rotation and in the direction of the central axis of rotation against the urging force of the urging member and a position of the operation lever is subsequently held, and an activation operation mode for setting the locking mechanism in the activated state as the operation lever is automatically made to undergo returning movement by the urging force of the urging member from the deactivation operation mode. Since the operation lever requires a two-stage operating motion about the central axis of rotation and in the direction of the central axis of rotation against the urging force of the urging member, the locking mechanism is prevented from being deactivated unnecessarily.
