A seat belt retractor includes a housing including a pair of side walls facing each other, a winding drum configured to wind up a webbing, a locking base being prevented from being rotated in the pull-out direction, in an emergency of a vehicle, an impact energy absorbing member connecting the winding drum and the locking base so as to be integrally rotatable in a normal state, an impact energy absorbing wire housed in a slot provided in the winding drum so as to form an opening in the first end surface of the winding drum, a ring provided integrally with or separately from the locking base, and a stopper member being configured to define an allowable amount of relative rotation between the winding drum and the locking base in a case where the impact energy absorbing member absorbs the impact energy.

Seat belt retractor

A seat belt retractor includes a housing including a first side wall and a second side wall facing each other, a winding drum configured to wind up a webbing, a locking base, a torsion bar including one end side, which is opposite to the locking base, coupled to the winding drum without being rotatable relative to the winding drum, and the other end side coupled to the locking base without being rotatable relative to the locking base, a pretensioner including: a pretensioner casing attached to the first side wall; and a drive wheel attached to the locking base, a lock member located in the locking base, and a stopper member being screwed onto a male screw of the locking base.

A seat belt retractor includes a housing including a pair of side walls facing each other, a winding drum configured to wind up a webbing, a locking base prevented from being rotated in the pull-out direction, in an emergency of a vehicle, an impact energy absorbing member including a first end side coupled to the winding drum and a second end side coupled to the locking base, the impact energy absorbing member connecting the winding drum and the locking base so as to be integrally rotatable, in a normal state, at least one impact energy absorbing wire housed in at least one slot that is provided in the winding drum, and a stopper member configured to define an allowable amount of relative rotation between the winding drum and the locking base in a case where the impact energy absorbing member absorbs the impact energy.

A seat belt anchor device according to one aspect includes: an anchor plate including a loop attached portion for a seat belt webbing, and having an opening including an enlarged region into which a head of a stud is allowed to be inserted and a lock region in which the head of the stud is not allowed to enter from the enlarged region but a shank of the stud is allowed to enter; a protector attached to the anchor plate and including a bridge portion disposed over the enlarged region on a side opposite to a vehicle body with respect to the enlarged region so that the loop is held between the protector and the loop attached portion; and a stopper attached to the anchor plate and configured to engage with the head of the stud when the shank of the stud enters the lock region from the enlarged region.

Seat belt anchor device

A seatbelt retractor that includes a locking mechanism to prevent rotation of a spool in an extracting direction, a ratchet gearand a locking gearthat integrally rotate with the spool, a clutchthat moves a pawlfrom a rest position to an engaging position with respect to the ratchet gear, a clutch biasing member that biases the clutchin a retracting direction and in a extracting direction, and a connecting mechanism to connect the clutchto the locking gear. When extraction of the webbing is locked, a direction of biasing to rotate of the clutchis maintained in the extracting direction so that the amount of retraction of the webbing required to release the lock is reduced to achieve quick release of the lock.
