PROBLEM TO BE SOLVED: To provide a belt pulling tool of occupant restraining device, whose cost and weight are decreased, with which a draw-in cable is prevented from receiving a thermal load from a high temp. gas. SOLUTION: A belt pulling tool of an occupant constraining device, in particular of buckle type, is composed of housings 3 and 5, gas generator, a working space 17 in which a compressed gas to be released at the time of constraint flows in, a piston 7 put in movement within the working space by the compressed gas, a belt engage device to be in relationship to make transmission of the fastening belt force, and a draw-in transmission device extending via the working space 17, wherein the draw-in transmission device 11 generates coupling of the belt engage device with the piston. The draw-in transmission device 11 is furnished at least partially with a covering made of a material having temperature stability against the action of a high temp. compression gas. |
