<p><P>PROBLEM TO BE SOLVED: To provide a cylinder structure for a pretensioner capable of enhancing freedom in manufacturing of the pretensioner and flexibility in mounting into a cabin. <P>SOLUTION: In the cylinder structure for the pretensioner mounted into the cabin, pulling/taking a seat belt buckle through a piston 12 inserted into a cylinder 1b and restricting an occupant by the seat belt, on an end part 13a at an opposite side to the seat belt buckle of the cylinder 1b, a pair of notch parts 13c, 13c is formed so as to be opposed to each other in a radial direction. Further, the end part 13a is formed such that a part is closed by bending a pair of tongue parts 13b, 13b remained without being notched at the end part 13a toward the inside of the cylinder 1b. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
