PURPOSE: To constantly hold a detector base plate horizontally in accordance with a seat back position by pivotally installing a ballincluding impact detector on an axial line passing a range where an impact lever of it gets in contact with a lock claw actuation member to freely oscillate by a screw nut mechanism. CONSTITUTION: For composing a ball-including impact detector, a ball 21 is provided between a base plate 16 having a spherical socket recess and an impact lever 12, so by move of the ball 21 at the time of impact, the impact lever 12 gets in contact with an actuation member 13 of a lock claw 7 to lock by engagement with a claw part 9 of a lock wheel 10 of a seat belt winding part. The detector is pivotally installed on a pin 26 on an axial line passing a contact range of the impact lever 12 with the actuation member 13, and it is set to freely oscillate to a main body 1 by a moving mechanism by a screw 32 and a nut 30. The base plate 16 of the detector is constantly held horizontal in accordance with an inclination position of a seat back part where the detector is installed, thereby correct actuation of the detector is secured. |
