Patent number: 8931850Abstract: A seat back frame includes a main frame that forms a frame of a seat back of a main seat, and an auxiliary frame that forms a frame of a seat back of an auxiliary seat adjacent to the main seat in a width direction, and that is integrally formed with the main frame. The main frame has a first open portion that opens toward a side with the auxiliary seat in the width direction. An end portion of the auxiliary frame is a fitting structure that fits together with the first open portion, and a portion of the fitting structure is welded.Type: GrantFiled: October 12, 2012Date of Patent: January 13, 2015Assignees: Toyota Boshoku Kabushiki Kaisha, NHK Spring Co., LtdInventors: Atsutaka Mitsuhashi, Ryoshu Nakane, Koji Murayama

Patent number: 8439443Abstract: A vehicle seat includes an operating member that is provided for a seat back. The operating member is operated to release locking of a seat cushion to a floor and to release rotation-sopped state of a reclining device. By operating the operating member, a first link rotatably provided for the seat back is operated in one rotation direction to thereby turn a second link rotatably provided for a base frame so that locking of the seat cushion to the floor is released. When the seat back is tilted forward, the first link is moved together with the seat back in a direction to be separated from the second link, that is, in a direction opposite to a direction in which the first link turns the second link.Type: GrantFiled: August 4, 2010Date of Patent: May 14, 2013Assignees: Toyota Boshoku Kabushiki Kaisha, Toyota Jidosha Kabushiki Kaisha, Aisin Seiki Kabushiki KaishaInventors: Ryoshu Nakane, Toshinao Wada, Kazuya Iwasa

Patent number: 7866754Abstract: A headrest for a vehicle seat has a tubular stay to be attached to a seatback and a connector to be connected to an end of the stay. The stay includes a shaft hole, an attachment hole, and a notched surface. The attachment hole penetrates from an outer surface of the stay to the shaft hole in the radial direction. The notched surface is circumferentially adjacent to the attachment hole and is substantially orthogonal to the attachment hole. The connector includes a cantilevered locking strip to be inserted into the shaft hole while being resiliently deformed. The locking strip includes a projection. The projection fits in the attachment hole by being resiliently restored. And the projection includes an extending portion being wider than the circumferential width of the attaching hole and extending over the notched surface by being resiliently restored.Type: GrantFiled: September 15, 2008Date of Patent: January 11, 2011Assignee: Toyota Boshoku Kabushiki KaishaInventors: Kenji Furukawa, Kimitaka Ando, Ryoshu Nakane

Patent number: 7740319Abstract: A headrest for a vehicle seat has a base member attached to a seatback of the vehicle seat, a body frame attached to the base member so as to be capable of tilting, a locking device for locking the body frame with the base member so as not to be capable of tilting, and an unlocking device for unlocking the locking device. The unlocking device includes a swinging body attached to the base member so as to be capable of swinging and a moving body attached to the body frame so as to be capable of moving with respect thereto. The moving body moves with respect to the body frame by being pushed by the swinging body to unlock the locking device. The swinging body has a connecting portion to which one end of a cable is connected and an arcuate-shaped outer peripheral surface on which the cable is disposed. And the cable is retracted into a tubular portion provided on the base member from an entrance of the tubular portion when the cable is pulled to unlock the locking device.Type: GrantFiled: September 15, 2008Date of Patent: June 22, 2010Assignee: Toyota Boshoku Kabushiki KaishaInventors: Kenji Furukawa, Kimitaka Ando, Ryoshu Nakane
