<P>PROBLEM TO BE SOLVED: To absorb and mitigate a load applied on an occupant with a simple configuration when an energy absorption action of an energy absorption member is completed by a stopper. <P>SOLUTION: A load acting on a seat belt is limited by a torsion bar 12 when a spool 9 and a rocking base 20 are rotated relative to each other. When the spool 9 is rotated a predetermined amount relative to the rocking base 20, a stopper 23 presses an EA (Energy Absorption) member 27 to grip the EA member 27 between the stopper 23 and the body section 20a of the rocking base 20. When the spool 9 is further rotated relative to the rocking base 20, the stopper 23 presses and crushes the EA member 27 to perform a seat belt load limiting operation. When the movement of the stopper 23 is stopped, the seat belt load limiting operation by the torsion bar 12 is completed. Thus, the seat belt load limiting operation by the EA member 27 is performed immediately before the seat belt load limiting operation by the torsion bar 12 is completed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
