Patent number: 10688957Abstract: In a lift-up buckle device, a slider and a shoe move forward and a buckle is moved to a stowed position. The shoe impacts against a protruding portion at a lower portion of a damper and interferes with a housing via the lower portion of the damper. Thus, the forward movement of the slider and shoe is stopped, while the damper absorbs an impact against the slider and shoe. Therefore, an amount of the impact against the slider and shoe that is absorbed by the damper may be increased by the protruding portion, and the damper may absorb the impact against the slider and shoe effectively.Type: GrantFiled: August 24, 2017Date of Patent: June 23, 2020Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Naoya Watanabe, Takuhiro Saito, Yasunori Hata, Makoto Matsuzaki, Yusuke Watada, Tatsuhiro Murasaki

Patent number: 10399538Abstract: In a buckle device, a pressing force, applied from wire ropes to an inside wall face of a wire guide groove of a wire guide, is along an imaginary line passing through a center of a cover plate first hole portion of a cover plate fixing tab of a cover plate and a center of a wire guide hole portion of the wire guide as viewed from the vehicle inside, similarly to a pressing force applied to a first fixing bolt that fixes the cover plate to a support plate, and these pressing forces are both oriented in the same direction. This enables rotation moment to be suppressed from occurring at the cover plate when the wire ropes are pulled toward their length direction leading end side.Type: GrantFiled: January 19, 2017Date of Patent: September 3, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Yasunori Hata, Takuhiro Saito, Tatsuhiro Murasaki, Yusuke Watada

Patent number: 10220811Abstract: A reduction in the durability of a coupling member coupled to a buckle is suppressed. A lift-up buckle device includes a buckle that engages with a tongue inserted through webbing worn by an occupant, and wires that each have a portion fixed to the buckle and that are displaced to move the buckle. The lift-up buckle device also includes a wire guide that includes a guide groove that guides the wires, and a soft lower cover that engages with the wire guide and covers the wires. A dimension of an end portion on the buckle side of the guide groove is set so as to increase on progression toward the buckle side.Type: GrantFiled: January 19, 2017Date of Patent: March 5, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Tatsuhiro Murasaki, Takuhiro Saito, Yasunori Hata, Yusuke Watada, Koji Hayashi, Makoto Matsuzaki

Patent number: 10124760Abstract: Load input to an occupant from a buckle is reduced. A lift-up buckle device includes a buckle that engages with a tongue inserted through webbing worn by an occupant. The lift-up buckle device also includes wires that each include a portion configuring a first fixed portion fixed to the buckle side and another portion configuring a supported portion supported by a wire guide, and that move the buckle due to a distance between the fixed portions and the supported portions being changed. Respective locations between the fixed portions and the supported portions of the wires are displaced in a direction intersecting an engaged direction of the tongue when an external force in a direction of the engaged direction of the tongue has been input to the buckle.Type: GrantFiled: January 19, 2017Date of Patent: November 13, 2018Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Yusuke Watada, Takuhiro Saito, Yasunori Hata, Tatsuhiro Murasaki

Patent number: 9974364Abstract: In a seat belt device, when a buckle cover is moved obliquely upward in a vehicle forward direction relative to a buckle guide and the buckle cover reaches a moving endpoint at a vehicle upper side relative to the buckle guide, cover-side engagement portions of the buckle cover become sandwiched between vehicle lower side surfaces of guide-side engagement portions of the buckle guide, and the outside surfaces of guide long-side wall portions of the buckle guide. Due to this, not only movement of the cover-side engagement portions of the buckle cover in the vehicle upward direction but also movement of the cover-side engagement portions outwards in the thickness directions of the cross-sectional shapes of the buckle cover and the buckle guide are restrained by the guide-side engagement portions.Type: GrantFiled: April 13, 2016Date of Patent: May 22, 2018Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Tatsuhiro Murasaki, Takuhiro Saito, Makoto Matsuzaki, Koji Hayashi, Hiroto Tanaka

Patent number: 9975512Abstract: An air belt device is provided with a webbing that is fitted around a vehicle occupant who is sitting in a vehicle seat, and an airbag portion that is provided in parallel with the webbing and is inflated and deployed when gas is supplied to an interior thereof. The airbag is provided with a reference portion that forms a portion of the airbag and is formed as a result of the airbag being folded. The airbag is also provided with a slack portion that forms another portion of the airbag and is formed as a result of the airbag being folded, and that extends in parallel with the reference portion and whose dimension in the transverse direction of the webbing is set longer than a dimension in the transverse direction of the webbing of the reference portion.Type: GrantFiled: June 12, 2015Date of Patent: May 22, 2018Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Ryu Nakashima, Masaru Ukita, Shinichi Okubo, Tomonari Umakoshi, Haruhiko Hashimoto, Tatsuhiro Murasaki

Publication number: 20180056930Abstract: In a lift-up buckle device, a slider and a shoe are provided at a seatbelt device. The slider and the shoe are moved by a drive screw that is driven by an output shaft of a motor. Here, a buffering body is provided at the output shaft, and concave portions are formed at corner portions of an inserted-into portion. Therefore, projecting portions which project-out into the inserted-into portion being formed at the corner portions of the inserted-into portion when the buffering body is molded can be suppressed, and corner portions of the output shaft interfering with the projecting portions can be suppressed. Accordingly, because rattling of the output shaft within the inserted-into portion can be suppressed, operating noise can be reduced.Type: ApplicationFiled: August 25, 2017Publication date: March 1, 2018Inventors: Tatsuhiro MURASAKI, Takuhiro SAITO, Yasunori HATA, Yusuke WATADA
