摘要： PROBLEM TO BE SOLVED: To provide a kinetic energy absorbing member for absorbing the kinetic energy when a member to be drawn in such as a buckle, lap anchor, etc. reaches the bottom portion during its operation, being constructed in a simple shape and manufactured at low cost. SOLUTION: The kinetic energy absorbing member 15 consists of a cylindrical member in an elliptical shape having a small wall thickness made of metal such as iron, aluminum, etc. and is installed between a bracket and the buckle in such an arrangement that its axial direction is identical to the buckle draw-in direction. The inside of this member 15 is penetrated by two wire portions 5a and 5b of a wire 5 arranged in U-turn around a pulley 6 of the buckle 4. By actuation of a pretensioner, the buckle is drawn in through the wire 5 to cause the energy absorbing member 15 to be pinched in the area with the bracket, and the member 15 collapses so as to absorb the kinetic energy of the buckle when reaching the bottom portion.

摘要： PROBLEM TO BE SOLVED: To reduce the rattling of a force transmitting member by efficiently transmitting the pressing force of a spring to the force transmitting member through a piston in a non-operating state.SOLUTION: A recess 25h curved in a circular arc shape is formed in the outer peripheral side surface 25f of the piston 25 of a pretensioner 8. In the initial state of setting of the piston 25, the recess 25h is in close contact or substantially in close contact with a portion 10dof the inner peripheral surface 10d on the curved inner peripheral side 10f of the curved section 10e of a pipe 10. As a result, even if the outer peripheral side surface 25f of the piston 25 is set at the curved section 10e of the pipe 10, the amount of lapping of the outer peripheral side surface 25f of the piston 25 on the portion 10dof the inner peripheral surface 10d of the curved section 10e of the pipe 10 can be reduced. This means that the sliding resistance between the piston 25 and the pipe 10 can be smaller in comparison to a solid cylindrical piston which does not have a recess in the outer peripheral side surface thereof.

摘要： PROBLEM TO BE SOLVED: To provide a pretensioner which enhances reliability of a restraining function of a push-in displacement of a wire. SOLUTION: A wire retaining groove 22 is formed in a housing 21 via a curved section, and a wire 23 for retaining a seat belt buckle 27 onto an upper end protruding from the wire retaining groove 22 is slidably held therein. When a gas generator 35 is activated and acts toward an edge extending in the vehicle longitudinal direction of the wire 23, the wire 23 is slidably displaced in the direction of pulling in the seat belt buckle 27. A tongue piece 21a protruding inside the wire retaining groove 22 restricts the wire 23 from being pushed in due to a wire push-in load applied to the wire 23 from the seat belt buckle 27. The wire 23 is allowed to be pulled in upon the activation of the gas generator 35. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a pretensioner capable of effectively absorbing kinetic energy added to a connecting member connected to a piston in working. SOLUTION: Gas is introduced to a pressure chamber 10 when a gas generator 11 works and the gas is generated in emergency. Consequently, the piston 7 moves to a taper part 8a of a cylinder 8 at high speed by gas pressure of this gas and makes contact with the taper part 8a of the cylinder 8. A buckle 4 is pulled to a bracket 2 and comes be immediately before hitting its bottom by movement of this piston 7. Thereafter, the piston 7 moves further to the left while deforming the taper part 8a and the kinetic energy of the piston 7 is absorbed by deformation of this taper part 8a. Consequently, the buckle softly stops as its kinetic energy is absorbed, and its impact is moderated. COPYRIGHT: (C)2006,JPO&NCIPI
