Abstract
A webbing retractor is provided that enables elimination of the part of a webbing belt left in the spool in an entirely pulled-out state of a webbing belt. A space portion is formed in a notched shape in an ALR switch lever. A cam projection of a cam plate that presses the ALR switch lever and changes it to the engaging direction side to a spool enters into the inside of the space portion and, thereby, the cam projection can rotate to an advanced position at the cam pull-out direction side with respect its contact position with the ALR switch lever, whereby the webbing belt can be pulled out entirely.
Claims9
A webbing retractor comprising:
- a spool to which a base end of a long strip-shaped webbing belt is engaged, and that takes up and stores the webbing belt, and rotates when the webbing belt is pulled out to feed the webbing belt out;
- a pressing member that moves in conjunction with the rotation of the spool;
- and
- an engaging member that can move in an engaging direction to directly or indirectly engage with the spool and also in the opposite direction thereto;
- wherein
- the engaging member is pressed by the pressing member moving in conjunction with the spool, and moves in the engaging direction, when the spool rotates until just before the webbing belt is entirely pulled out, and
- a space portion is formed at the engaging member so as to open toward the pressing member side in the moving state of the engaging member in the engaging direction;
- and
- when the spool rotates until the webbing belt is entirely pulled out, the pressing member moving in conjunction with the spool enters inside of the space portion of the engaging member.

A webbing retractor comprising:
- a spool to which a base end of a long strip-shaped webbing belt is engaged, and that takes up and stores the webbing belt, and rotates when the webbing belt is pulled out to feed the webbing belt out;
- a pressing member that moves coaxially with the spool in conjunction with the rotation of the spool, and at which a projection is formed to project in parallel with a rotation axis of the spool at an outer side in a rotation radial direction relative to a rotational center of the spool;
- and
- an engaging member that can move in a direction toward a rotational center of the pressing member to directly or indirectly engage with the spool;
- wherein
- the engaging member is pressed by the projection moving in conjunction with the spool, and moves in the direction toward the rotational center of the pressing member, when the spool rotates until just before the webbing belt is entirely pulled out, and
- a space portion is formed at the engaging member so as to open toward the projection side in the moving state of the engaging member toward the rotational center of the pressing member, and
- when the spool rotates until the webbing belt is entirely pulled out, the projection moving in conjunction with the spool enters inside of the space portion of the engaging member.

A webbing retractor in which a long strip-shaped webbing belt is taken up and stored by a spool to which a base end of the webbing belt is engaged, and when the webbing belt is pulled, the spool rotates in one direction around its own axis and the webbing belt is pulled out, and when the webbing retractor is assembled into a vehicle, the webbing belt is in an initial state where the entire webbing belt is pulled out, comprising:
- a pressing member that moves coaxially with the spool in conjunction with the rotation of the spool, and at which a projection is formed to project in parallel with a rotation axis of the spool at an outer side in a rotation radial direction relative to a rotational center of the spool;
- and
- an engaging member that can move in a direction toward and away from a rotational center of the pressing member and directly or indirectly engages with the spool when moving toward the rotational center of the pressing member;
- wherein
- the engaging member has a main body and a projecting portion, and the projecting portion is formed to extend toward a rotation trajectory of the projection of the pressing member, and
- when the projecting portion is pressed by the projection just before the webbing belt is entirely pulled out, the main body moves toward the rotational center of the pressing member, and
- a space portion is formed at the engaging member so as to open toward the projection side in the moving state of the engaging member toward the rotational center of the pressing member, and
- when the spool rotates until the webbing belt is entirely pulled out, the projection moving in conjunction with the spool enters inside of the space portion, and
- in the initial state, the projection is arranged at the same position as that of the projection in the state where the webbing belt is entirely pulled out.
6 more elements
A webbing retractor comprising:
- a spool to which a base end of a long strip-shaped webbing belt is engaged, and that takes up the webbing belt;
- a pressing member that moves in conjunction with the rotation of the spool and presses an engaging member;
- and
- the engaging member, which can move in an engaging direction to directly or indirectly engage the spool and also in the opposite direction to the engaging direction, and at which a space portion to house the pressing member is formed, wherein
- in a state where the webbing belt is entirely pulled out from the spool, the pressing member is housed in the space portion.
2 more elements
A webbing retractor comprising:
- a spool to which a base end of a long strip-shaped webbing belt is engaged, and that takes up the webbing belt;
- a pressing member that moves in conjunction with the rotation of the spool, and presses an engaging member;
- a rotating body that is coaxial and rotatable relative to the spool;
- a locking member that engages with the spool and regulates the rotation of the spool in a pull-out direction of the webbing belt;
- the engaging member, which is arranged in the rotating body, and can move in an engaging direction to engage directly or indirectly with the spool and also in the opposite direction to the engaging direction, wherein a space portion to house the pressing member is formed, and wherein in a state where the webbing belt is entirely pulled out from the spool, the pressing member is housed in the space portion;
- a rotation engaging member that is arranged in the rotating body, and rotates together with the rotating body in the pull-out direction of the webbing belt, and makes the locking member engage with the spool in accordance with the rotation;
- and
- a connecting member that is arranged in the rotating body, and connects the rotating body with the spool, and makes the rotating body rotate in the pull-out direction together with the spool.
