Patent number: 10688886Abstract: The vehicle seat includes a seat cushion and a seat back. The seat back includes one shaft member, a mount frame having a first bearing and a second bearing, and a first operation section and a second operation section which are arranged side by side. The shaft member is attached to the first and the second bearings, having no fixing section for the mount frame between the first and the second bearings, and serving as a center around which the first and the second operation sections are rotated.Type: GrantFiled: April 15, 2018Date of Patent: June 23, 2020Assignee: TACHI-S CO., LTD.Inventors: Norito Akimoto, Masaaki Honda

Patent number: 10391888Abstract: A seat moves along a rail in the front-back direction of a vehicle. A juxtaposed member (receiving member) extending in the front-back direction of the vehicle is joined to a floor or the seat so as to be located next to the rail. A detected portion is provided either to the juxtaposed member or to a member which is located on the floor side or the seat side which moves relative to the floor or the seat to which the juxtaposed member is coupled. A sensor that detects the detected portion is provided either to the juxtaposed member or to the member located on the floor side or the seat side. As a result of this configuration, the installation position of the sensor is less spatially restricted than the case in which the sensor is provided to the rail.Type: GrantFiled: February 22, 2016Date of Patent: August 27, 2019Assignee: TACHI-S CO., LTD.Inventors: Hiroyuki Nozaki, Yohei Ota, Norito Akimoto, Masaaki Honda

Patent number: 9827880Abstract: Vehicle seat including: a seat back pivoted to a side of the floor, a seat cushion pivoted to the seat back; and a front leg element having an upper end pivoted to the seat cushion and a lower end pivotally locked to the side of floor in a releasable manner, thus normally providing a four-pivotal-point linkage in the seat. Maintaining the four-pivotal-point linkage adversely restricts design and actions of the seat. Inequality conditions are therefore set in that four-pivotal-point linkage, such that folding down the seat back by an angle exceeding a predetermined angle results in unlocking of the lower end of the front leg element from the side of floor, thereby destroying the four-pivotal-point linkage. Hence, a freedom of design is increased for the seat and floor. Further, leverage mechanism(s) may be provided to facilitate the ease of unlocking the front leg element from the side of floor.Type: GrantFiled: May 18, 2017Date of Patent: November 28, 2017Assignee: TACHI-S CO., LTD.Inventors: Minoru Fukutani, Norito Akimoto
