Patent number: 9533604Abstract: A seat slide device is fixed to the floor of a vehicle and includes lower rails, each of which includes a front range and a rear range and extends forward and backward, and an upper rail supporting a movable seat and capable of moving over the lower rails. The seat slide device also includes a lock portion, a stopper, and a stopper-releasing operating portion. The lock portion selectively restricts movement of the upper rail on the lower rails at a plurality of positions. The lock portion is provided to the upper rail. The stopper stops movement of the upper rail before the upper rail advances from either one of the front range and the rear range, past this range, to the other range. The stopper-releasing operating portion enables movement of the upper rail when the upper rail has been stopped by the stopper.Type: GrantFiled: February 6, 2013Date of Patent: January 3, 2017Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Shirou Nakashima, Manabu Handa, Takahiro Sugama, Hideki Fujisawa, Sho Kume, Tsutomu Oya

Patent number: 8562060Abstract: A vehicle seat device in which a seat can be simply and reliably held at a storage position. In a vehicle seat, a vehicle width direction outer side end portion of a seat cushion is supported so as to be capable of rotating around a drive shaft having an axis along a vehicle front-rear direction, and the seat cushion can be switched between a seating configuration at which an occupant can be seated and a storage configuration at which the seat cushion stands erect along a vehicle cabin inner side surface, due to being rotated around the drive shaft by a driving motor. Further, the vehicle seat which is in the storage configuration is held at the storage configuration by a striker.Type: GrantFiled: September 6, 2007Date of Patent: October 22, 2013Assignees: Toyota Shatai Kabushiki Kaisha, Toyota Boushoku Kabushiki KaishaInventors: Hideyuki Kato, Takahiro Sugama, Masami Natsume, Tetsuya Abe

Publication number: 20120139312Abstract: The invention provides a vehicle seat device in which a seat can be simply and reliably held at a storage position. In a vehicle seat (10), a vehicle width direction outer side end portion of a seat cushion (12) is supported so as to be capable of rotating around a drive shaft (30) having an axis along a vehicle front-rear direction, and the seat cushion can be switched between a seating configuration at which an occupant can be seated and a storage configuration at which the seat cushion (12) stands erect along a vehicle cabin inner side surface S, due to being rotated around the drive shaft (30) by a driving motor (42). Further, the vehicle seat (10) which is in the storage configuration is held at the storage configuration due to a striker (46) engaging with a seat dragger (48) and is configured such that the striker (46) is released from the seat dragger (48) at the time of switching to the seating configuration.Type: ApplicationFiled: September 6, 2007Publication date: June 7, 2012Applicants: TOYOTA BOSHOKU KABUSHIKI KAISHA, TOYOTA SHATAI KABUSHIKI KAISHAInventors: Hideyuki Kato, Takahiro Sugama, Masami Natsume, Tetsuya Abe

Patent number: 7954873Abstract: A striker is supported by and coupled to a seat body and is held in a rotated position where the striker is lowered to a position along the shape of the seat body. When the seat body is moved and stowed, the striker is raised to and held at a rotated and raised position where the striker can be engaged and locked to a locking device. Elasticity of an opening spring and a rubber body, which are arranged between the striker and a coupling section, allows a forced rotational displacement of the striker in both forward and reverse directions from a state in which the striker is held at the rotated and raised position.Type: GrantFiled: October 12, 2007Date of Patent: June 7, 2011Assignees: Toyota Boshoku Kabushiki Kaisha, Toyota Shatai Kabushiki KaishaInventors: Tetsuya Abe, Takahiro Sugama, Masami Natsume, Yasuhiro Nishii

Publication number: 20110095585Abstract: The invention provides a vehicle seat device including fewer restrictions with respect to seat function and which can be switched from a seating position to a storage position by motive power. In a vehicle seat (10), a vehicle width direction outer side end portion of a seat cushion (12) is supported so as to be capable of rotating around a drive shaft (30) having an axis along a vehicle front-rear direction, and the seat cushion can be switched between a seating configuration at which an occupant can be seated and a storage configuration at which the seat cushion (12) stands erect along a vehicle cabin inner side surface S, due to rotating around the drive shaft (30).Type: ApplicationFiled: September 6, 2007Publication date: April 28, 2011Inventors: Hideyuki Kato, Takahiro Sugama, Mikihito Muramatsu

Patent number: 7753428Abstract: Disclosed is a vehicle seat device operating as follows. A retracting instruction is given by a seat switch to start operation of a seat back actuator. Lock of the seat back and a seat cushion is released to rotate the seat back to the position where it is overlapped with the seat cushion. A floor actuator is driven to release engagement between the floor panel and the floor lock. A lift up motor is operated to lift up the vehicle seat device toward the vehicle body. After this, a dragger lock motor is operated to lock a striker on the seat back rear surface and the dragger unit, thereby completing the retraction operation.Type: GrantFiled: April 17, 2007Date of Patent: July 13, 2010Assignees: Toyota Jidosha Kabushiki Kaisha, Toyota Shatai Kabushiki Kaisha, Toyota Boshoku Kabushiki KaishaInventors: Hideyuki Kato, Takahiro Sugama, Masami Natsume, Takahiro Kan, Mikihito Muramatsu

Patent number: 7293838Abstract: A seat for a vehicle has an upper panel provided integrally with a seat back which can be tilted forward and rearward by operating an operation lever for reclining use. At a first operation position of an operation lever for walk-in use, the operation lever for walk-in use is interlocked with the operation lever for reclining use through a linking arm to tilt the upper panel urged by a spring forward. A projected piece mounted on the upper panel contacts a slide-unlocking lever and operates the slide-unlocking lever to rotate in an unlocking direction. Thereby slide locking of the seat for the vehicle is released. At a second operation position of the operation lever for walk-in use, the slide-unlocking lever is operated directly by a linking plate. Thereby the slide locking of the seat for the vehicle is released.Type: GrantFiled: January 23, 2006Date of Patent: November 13, 2007Assignees: Toyota Shatai Kabushiki Kaisha, Toyota Boshoku Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Takahiro Sugama, Makoto Esaki, Takashi Mukoujima

Patent number: 6021989Abstract: A swivel assembly of a vehicle seat including a ring-shaped upper plate fixed to a seat side member of a vehicle; a ring-shaped lower plate fixed to a floor side member of the vehicle; and a set plate holding the upper plate between it and the lower plate. One ball is provided between the upper plate and the lower plate. The other ball is provided between the upper plate and the set plate. The other ball is in contact with both inner surfaces of each of one sectionally V-shaped guide groove and the other sectionally V-shaped guide groove confronting the one groove. The upper plate can be held at a predetermined position without being loosened vertically and horizontally even though the upper plate, the lower plate, and the set plate have errors occurred in manufacture.Type: GrantFiled: December 15, 1997Date of Patent: February 8, 2000Assignee: Toyota Shatai Kabushiki KaishaInventors: Shinji Morita, Koichi Yamamoto, Takahiro Sugama, Hisayoshi Kato, Kyoji Inoue, Teruhiko Oshima
