Patent number: 9802513Abstract: A seat includes a pivotally movable bottom, a pivotally movable backrest independent from the bottom, a first supporter suspending and supporting a front side of the bottom, and a second supporter suspending a rear side of the bottom from a side behind the backrest section, and pivotally movably supporting the bottom together with the first supporter. According to the seat, the front side and the rear side of the bottom are suspended and supported. Thus, compared to a seat in which a front side of a bottom is supported in a cantilever manner, the seat is capable of ensuring bearing capacity for a seating load. The rear side of the bottom is suspended and supported from a side behind the backrest section. Accordingly, a support structure around the bottom including the front side of the bottom can be downsized.Type: GrantFiled: July 24, 2013Date of Patent: October 31, 2017Assignee: TOYOTA JIDOSHIA KABUSHIKI KAISHAInventors: Kohshi Katoh, Eishi Takeuchi, Yasuhiro Suwa, Yasuhiro Inuzuka

Patent number: 9671782Abstract: There is provided an autonomous driving device that improves the convenience for a driver in the switching between autonomous driving and manual driving. When the driver discovers an obstacle which cannot be detected by an autonomous driving device, and performs a driving operation which causes a manual driving switching threshold value to be exceeded for an operation time less than or equal to an operation threshold value so as to avoid the obstacle, a control unit of the autonomous driving device switches autonomous driving to manual driving, and then the control unit switches manual driving to autonomous driving even if the driver does not perform an autonomous driving switching operation. For this reason, it is possible to improve the convenience for the driver in the switching between autonomous driving and manual driving.Type: GrantFiled: October 8, 2015Date of Patent: June 6, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masaaki Yamaoka, Kohshi Katoh, Eishi Takeuchi, Tomoyuki Kuriyama, Hikaru Sato
