<p>PROBLEM TO BE SOLVED: To maintain the control effect of a gas bag by making tensile force act on the gas bag at a final position to strain the gas bag at a specified position inside a vehicle for restraining movement and the variation of the position even if the vehicle deforms. SOLUTION: A lock body 19 is pulled from a contact face by the expansion of a gas bag 1 and released, and stored spring energy is therefore liberated to move a traction cable 9 downward, A control device composed of the traction cable 9, a driving device 12, a latch device and a return lock 23 accelerates the unfolding of the gas bag 1, and leads it to a requested position in a state where the gas bag completely expands into the shape of a cushion. The gas bag 1 is pulled between an upside peripheral edge 3 and an eyelug 7 to make a support for a side window having the possibility of fracture unnecessary, and the return lock 23 checks the movement of the traction cable 9 toward the outside of a specified position when the crew nember is given a shock to his head for making the movement of the gas bag 1 impossible.</p> |
