ABSTRACT:
A buckle device for use in vehicle seat belt system having a tongue plate and a buckle body into which the tongue plate is inserted for engagement therewith includes a lock member which is swung to engage the inserted tongue plate and is adapted to lock the tongue plate, a release button moved by the operation of a vehicle occupant to swing the lock member in an opposite direction, thereby cancelling engagement between the lock member and the tongue plate, and an emergency lock mechanism for holding the lock member in a state of engagement with the tongue plate when an inertial force acts in an operating direction of the release button. Accordingly, the disengagement between the tongue plate and the lock member due to the inertial force is prevented, and the state of engagement between the two members is maintained.
