20100147986 | WEBBING RETRACTING DEVICE - A webbing retracting device that may prevent entering of an end-lock state when a spool rotates in the pull out direction on rebound just after completion of taking up of the webbing belt. A restriction weight is provided on a V gear. The restriction weight moves in the pull out direction relative to the V gear by acceleration when the V gear is rotated in the take up direction, and furthermore, the restriction weight pivots about a support pin under centrifugal force due to rotation of the V gear and attains a contact position. In such a state, even if the inertial mass attempts to displace toward the lock activation direction, the restriction weight interferes with the inertial mass and restricts displacement of the inertial mass toward the lock activation direction. | 06-17-2010 |

20130248633 | FORCE LIMITING DEVICE, BELT RETRACTOR HAVING A FORCE LIMITING DEVICE, AND METHOD FOR SWITCHING OVER A FORCE LIMITING DEVICE - A force limiting device for a belt retractor is reversible from a higher restraining force level to a lower restraining force level by means of a reversing means during a force limiting phase, wherein the second restraining force level is largely determined by a performance of at least one force limiting element. The reversing means is arranged so that it accomplishes a significant work share upon reversing which is added to the performance of the force limiting element and thus temporarily increases the restraining force of the force limiting device. In this manner undershooting of the characteristic line of the force limiting device upon reversing to the lower restraining force level is compensated. | 09-26-2013 |

20090261193 | WEBBING RETRACTOR - A webbing retractor is provided that can structure a WSIR mechanism with a small number of parts. When a second gear, that is pivotally-supported so as to rotate freely at a trigger lever, revolves around a first gear while rotating around a shaft, the trigger lever pulls a lock pawl via a link and causes the lock pawl to mesh with a lock base, and rotation of a spool in a pull-out direction is restricted. With such a structure, a structure corresponding to a ring gear of a planetary gear train is not needed, and a locking mechanism can be structured by a small number of parts. | 10-22-2009 |
20110127363 | WEBBING TAKE-UP DEVICE - A webbing take-up device comprising a spool and a locking unit having a locking unit main body having a rotational acceleration detecting unit, wherein the rotational acceleration detecting unit comprises a second rotating body; a rotation transmission member provided at the second rotating body; an inertial mass body having a pressing portion and provided at the second rotating body; a biasing means provided at the second rotating body; and a retaining portion provided at the second rotating body to pinch the rotation transmission member together with the inertial mass body biased by the biasing means, thereby retaining the rotation transmission member in a state in which the rotation transmission member does not engage with the first rotating body, and to release retention of the rotation transmission member when relative rotation is produced between the second rotating body and the inertial mass body. | 06-02-2011 |
20110174911 | WEBBING WINDING DEVICE - Provided is a webbing winding device having a lock mechanism in which a driven body is less influenced by an inclination of a driving body. A peripheral wall extends from an edge portion of a penetration hole formed at a sensor gear constituting the lock mechanism toward a link member, and a guide hole is formed at a bottom wall formed at the front end of the peripheral wall. An engagement pin of the link member passes through the guide hole from the base end portion rather than the front end portion thereof in the protruding direction. Further, in the front end side of the engagement pin passing through and protruding from the guide hole, the outer peripheral portion is spaced apart from the inner peripheral portion of the peripheral wall. | 07-21-2011 |
20110290929 | WEBBING RETRACTOR - A webbing retractor includes a retracting shaft; a lock member regulating the rotation of the retracting shaft in the pulled-out direction; a rotating body connected to the retracting shaft; a rotation detecting member that is relatively displaced with respect to the rotating body by inertial force, by which rotation of the rotating body in the pulled-out direction is regulated, and by which the lock member is actuated; and a regulating member having an engaging portion that engages with the rotation detecting member because of the rotation of the rotating body in the retraction direction. The regulating member regulates the relative displacement of the rotation detecting member with respect to the rotating body resulting from rebound of the stopping of the retraction of the webbing, and the engagement of the engaging portion with the rotation detecting member is released as the engaging portion is displaced toward a radial direction inside of the rotating body by the rotation of the rotating body in the pulled-out direction. | 12-01-2011 |
20110290930 | WEBBING RETRACTOR AND METHOD OF MANUFACTURING ROTATION DETECTING MEMBER - In a webbing retractor, when a V gear has been rotated in a withdrawal direction following a spool and a W pawl has been relatively displaced with respect to the V gear by inertial force, the rotation of the V gear is regulated and a lock plate regulates the rotation of the spool. A first center-of-gravity adjusting hole and a second center-of-gravity adjusting hole are disposed in the W pawl, and the sensitivity of detecting the inertial force is adjusted as a result of a center-of-gravity position of the W pawl being adjusted. The first center-of-gravity adjusting hole and the second center-of-gravity adjusting hole are disposed away from an outer peripheral surface of the W pawl, so the center-of-gravity position of the W pawl becomes adjustable without having to change the outer peripheral shape of the W pawl. | 12-01-2011 |

20140008479 | WEBBING TAKE-UP DEVICE - In a placement face of which a general face is configured with a circular cone shape, restriction faces are formed. When a sensor ball rolls along an axial direction of rotating shafts, the sensor ball accordingly contacts one of the restriction faces or another of the restriction faces. From this state, in order for the sensor ball to roll further along the axial direction of the rotating shafts, the sensor ball has to rise up the one of the restriction faces or the other of the restriction faces that respectively have a larger angle of incline than the general face. By contrast, in order for the sensor ball to roll in directions orthogonal to the axial direction of the rotating shafts as seen in plan view, the sensor ball only has to roll over the general face. | 01-09-2014 |

Web retractors assemblies configured in accordance with various embodiments of the present technology can include, for example, a frame having a first sidewall and a second sidewall opposite the first sidewall, and a spring-loaded shaft extending between the first and second sidewalls. The web retractor can further include a locking mechanism positioned proximate to the first sidewall of the frame and operably coupled to the shaft. The locking mechanism can include a vehicle inertia sensor and/or a web inertia sensor. A cover can enclose the locking mechanism such that the cover and the first sidewall form a liquid-sealed enclosure around the locking mechanism. | 02-27-2014 |
20140197262 | WEBBING TAKE-UP DEVICE - The present invention provides a webbing take-up device that can effectively suppress tilt of a rotation body when an actuation member has been actuated. In a webbing take-up device, tilt restricting portions are provided at a V gear. The tilt restricting portions are provided at a radial direction inner side than a place of engagement between a W pawl and ratchet teeth of a sensor holder and project further toward a sensor holder side than an end surface at the sensor holder side, which end surface is at the outer side in the radial direction than the place of engagement. For this reason, tilt of the V gear with respect to its axial direction can be restricted. | 07-17-2014 |
