Title:
BUCKLE
Document Type and Number:
Japanese Patent JP3844179
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a buckle with a simpler structure allowing certain operation to effectively prevent inertia off.
SOLUTION: In this buckle 1, a lever 12f of an inertia lever member 12 advances to a movement passage of a lock pin 5 in a latching state of a tongue and the buckle 1. In that state, when a buckle pretensioner retracts the buckle l, the inertia lever member 12 moves in the longitudinal direction, and a turn prevention part 2m3 blocks a pressed part 12d. Accordingly, the inertia lever member 12 does not turn, and the lever 12f is held in the movement passage of the lock pin 5. At the time of a bottom strike accompanying retraction completion of the buckle 1, the inertia lever 12 does not turn to allow the hold of the lever 12f in the movement passage of the lock pin 5 because a moment caused by an inertia force acting on the gravity center G of a mass body 12b is set to be larger than a moment caused by action of an inertia force of an operation button 6 on the inertia lever member 12.
