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

Patent number: 8210607Abstract: A headrest is attached to a square frame-shaped seatback frame so that the headrest can be moved back and forth by an upper lever. The upper lever is connected by a connection rod to a lower lever provided at the seatback frame. Left and right connection arms of a rear collision detector are attached to the lower lever. Backward movement of the rear collision detector moves forward the headrest via the connection rod and the upper lever. The connection arms of the rear collision detector are fixed to the lower lever, held at a predetermined angle.Type: GrantFiled: December 20, 2006Date of Patent: July 3, 2012Assignee: TS Tech Co., LtdInventors: Wataru Takayasu, Masaki Nagayama

Patent number: 7513574Abstract: A light alloy seat back frame for a vehicle seat, including a pair of spaced apart side sections, an upper section interconnecting the side sections, a lower section formed into a substantially plate-shape having a width, the lower section extending between lower regions of rear sides of the side sections and interconnecting the side sections, the upper, side and lower sections being integrally made of light alloy, and a belt-shaped metal plate fixed onto a surface of the lower section. The seat back frame further includes a recliner mechanism for allowing a seat back of the vehicle seat to be pivoted with respect to a seat cushion of the vehicle seat. The recliner mechanism comprises cam devices mounted onto lower regions of outer surfaces of the side sections, and an actuating shaft extending along the lower section and interconnecting the cam devices. A metal pipe member for reinforcing a lower part of the seat back frame is mounted around an axial portion of the actuating shaft.Type: GrantFiled: July 20, 2005Date of Patent: April 7, 2009Assignees: TS TECH Co., Ltd., HONDA MOTOR Co., Ltd.Inventors: Masaki Nagayama, Nobuhiro Inomata, Isao Awano
