- the lock bar 30 comes into contact with the second engagement portion 64 as shown in FIG. 12D. Moves to the second position P2 without any change.
- the tundler plate 2 In this engagement-squared state, the tundler plate 2 is disengaged from the buckle body 5 in the forward direction. However, in the case of —, the front end of the ejector 140 is in contact with the rear end of the tundler plate 2. Therefore, the tonda plate 2 is urged forward and comes off.
- the pair of pushing portions 44 (FIG. 3) of the ejector 140 comes into contact with the pair of pushed portions of the release spot 50.
- the release button 50 is urged forward by the ejector 140 that is urged by the urging force of the coil spring 71, and the release button 50 returns to the forward limit position.
- the pretensioner is activated and the pack body 5 is bowed into the tightening side of the webbing by a predetermined amount, and the webbing firmly restrains the occupant.
- the lock members 60 and the like operate so that the tander plate 2 does not come off from the buckle body 5.
- the puckle body 5 When the pretensioner is actuated, the puckle body 5 is retracted to the tightening side of the webbing, that is, rearward, and then suddenly stops.Firstly, immediately after the puckle body 5 starts to move backward, the locking member 60 is turned forward. ffl; At this time, the inertia force acts as a rotating force for rotating the lock member 60 to the non-locking position, but the inertia force in the direction of the first position P1 also acts on the locking member 30.
- the inertia force and the lip of the coil panel 70 which urge the lip pad 30 to the first position P 1, hold the lip member 60 with the lock bar 30, so that the lip member 70 can be maintained at the lock position.
- the mass, the urging force, the pivotal support position of the mouth member 60, and the like of the member 60 and the mouth member 30 are set.
- the lock par 30 After the operation of the pretensioner, the lock par 30 returns from the second position P2 to the first position P1 by the urging force of the coil panel 70, whereby the lock member 60 is maintained at the lock position. As a result, the vehicle returns to the normal state, and the occupant can freely insert and remove the touch plate 2 from the buckle body 5. (Operation of the present invention)
- the lock par 3 comes into contact with the lock member 60 and the lock member 60 rotates to the lock position.
- the lock par 30 receives a force on the first engaging portion 63 side, so that the lock position is maintained, and the hook member-: 2: Rotation of 0- to the direction of disengagement is suppressed.
- inertia force is applied to the buckle body 5 in the tongue plate insertion direction, the zipper 30 moves to the second engagement portion 64 side, but the third engagement portion 66 contacts the release button 50.
- the contact locking member 60 does not rotate to the non-locking position, and the locking bar 30 stays in the second engagement portion 64, so that the tander plate 2 is not disengaged.
- the release button 50 When the release button 50 is operated, the lock member 30 is pushed out of the first engagement portion 63, and the urged lock member 60 moves to the unlock position.
- the third engaging portion 66 does not come into contact with the release button 50 because the hook member 60 rotates toward the unlocked position at a, so that the hook member 2 does not hinder the rotation to the unlocked position. 0 rotates in the engagement / disengagement direction, and the tander plate 2 can be disengaged.
- the lock bar 3 ⁇ abuts the second engagement portion 64 to rotate the lock member 60 to the unlock position.
- the third engagement portion 66 abuts against the relay button 50, so that the lock member 60 stays in the lock position, and the stander plate 2 is not released.
