Patent number: 5634690Abstract: When gas is generated in an emergency situation of a vehicle and a cylinder is driven, one of wires rotates a pulley via a small diameter portion of the pulley. For this reason, the other wire connected to a large diameter portion of the pulley has a length wound around the large diameter portion, which is longer than that of the one wire. A drive stroke of the cylinder is increased and transmitted to a seat belt buckle. As a result, even if the cylinder is of a small size, a long pulling stroke is applied to a seat belt.Type: GrantFiled: December 22, 1994Date of Patent: June 3, 1997Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Yasutaka Watanabe, Kenji Matsui, Hideki Tanaka

Patent number: 5358274Abstract: A shoulder anchor height adjusting apparatus movably adjusts the height of a shoulder anchor. The shoulder anchor is attached to a slider, which is supported by a rail extending from the upper portion of the side wall of the vehicle in the vertical direction so as to be guided along the rail. Further, the slider moves in the vertical direction of the vehicle so as to move the shoulder anchor in a likewise direction. A long bolt is disposed between the slider and the rail and at the upper portion of the side wall of the vehicle. The long bolt has an axis in the vertical direction of the vehicle, and is provided so as to be rotatable about the axis. An elevator nut is screwed into the bolt, and is moved in the vertical direction of the vehicle by rotation of the bolt. An arm outwardly extends from the slider in the transverse direction of the vehicle, has a contact portion for contacting the elevator nut.Type: GrantFiled: December 22, 1992Date of Patent: October 25, 1994Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventor: Yasutaka Watanabe

Patent number: 5337970Abstract: A preloader for use in a webbing retractor for retracting an occupant-restraining webbing forcibly onto a takeup shaft at the time of a sudden deceleration of a vehicle. The preloader includes a angular shaft rotating integrally with the takeup shaft; a deformable member disposed around the angular column shaft; and a wire connected to the deformable member and wound therearound. The wire is tightly wound around the deformable member at the time of a sudden deceleration of the vehicle, thereby causing the deformable member to undergo deformation and engage with the angular shaft. The angular shaft is hence rotated integrally with the deformable member so as to positively rotate the takeup shaft in a taking-up direction.Type: GrantFiled: August 6, 1991Date of Patent: August 16, 1994Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Keisuke Imai, Toshimasa Yamamoto, Akio Numazawa, Hitoshi Iwata, Yasutaka Watanabe
