Publication number: 20230373359Abstract: In a seat-rotating device that enables a seat to be rotated on a base member, a rattle-suppressing member operating in association with a lock member, which switches between the locked state in which rotation of an annular rotating member supporting a seat frame is prevented and release of the locked state, is in close contact with both a support member and the annular rotating member when the lock member is at the locked position, and a gap is created between the support member and the annular rotating member when the lock member attains the lock release position. Accordingly, it is possible to prevent the seat from rattling when it is in a stationary state and to facilitate rotation by releasing the rattle-preventing state when the seat is rotating.Type: ApplicationFiled: August 3, 2023Publication date: November 23, 2023Inventors: Haruki MOCHIZUKI, Takeshi AKUTSU, Takuji KANEDA

Patent number: 10906429Abstract: A seat slide structure includes a cushion frame, a slide rail including lower and upper rails, a movement mechanism, and a lock mechanism. The movement mechanism slides the cushion frame along a length direction of the slide rail. The lock mechanism includes a lock body engaging with the slide rail, and places or lifts a restriction on movement of the slide rail. The movement mechanism includes a lead screw, a gear part, and a shake absorber. The lead screw is provided in parallel with the slide rail, and is supported by the upper rail. The gear part transmits power from a power source to the lead screw to slide the lead screw and the upper rail along the lower rail. The shake absorber allows the cushion frame and the lead screw to move relative to one another in a moving direction of the upper rail along the lower rail.Type: GrantFiled: August 14, 2019Date of Patent: February 2, 2021Assignee: TS TECH CO., LTD.Inventors: Takeshi Akutsu, Tsukasa Meguro, Yuya Adachi, Masaki Nagayama, Chikara Hishinuma, Yuta Sugaya, Richard Orr, Jonathan Osborne
