CONSTITUTION: A seat belt is pulled to quickly restrain a passenger via an insertion tongue piece 46 locked to a fixture 22 and a belt lock 12 by generated pressure due to high pressure gas at the time of emergency, with actuation of a fastening device having an ignition-technological gas generator. A two- armed lever 66 is pivoted to a housing 32 of the belt lock 12 by a pin perpendicular to a guide channel 44 inserted with the piece 46. A compensation mass 68 is provided in one arm of the two-armed lever 66, and the other arm is engaged with a blocking member 54 or a release button 30. That is, a crank lug 70 engaged with the member 54, the button 30, or a recess 72 in a portion connected thereto is provided in the other arm. |
