Publication number: 20090322126Abstract: A headrest moving mechanism includes linking members that links a support portion and a headrest base portion to each other; and elongated holes formed in the headrest base portion. The elongated holes slidably receive a connection shaft provided to the support portion, thereby determining a postural position of the support portion. The elongated holes are shaped so as to move the support portion forwardly and upwardly with respect to the headrest base portion from an initial position in a time before the vehicle back-side collision happens to a collision preparatory position as the linking members are rotated.Type: ApplicationFiled: June 29, 2007Publication date: December 31, 2009Applicant: TOYOTA BOSHOKU KABUSHIKI KAISHAInventors: Takeshi Nishiura, Seiya Nishimura, Koji Hayashi, Atsuki Sasaki

Publication number: 20090315371Abstract: An operation cable has an operational structure in which an inner member inserted into a tubular outer member is pulled from a lower end side thereof. The operation cable having a double layer structure is axially connected to a double layer cable that is constructed from a stay of a headrest and a push rod inserted into the tubular stay. In particular, the stay is inserted into a support positioned on an upper portion of the seat back, a lower end of the stay and an upper end of the inner member are axially connected to each other, so that a lower end of the push rod in the tubular stay and a head portion of the outer member are positioned closer to each other. As a result, the push rod can be pushed by the head portion of the outer member when the operation cable is pulled.Type: ApplicationFiled: June 14, 2007Publication date: December 24, 2009Applicant: TOYOTA BOSHOKU KABUSHIKI KAISHAInventors: Toshihiro Shimizu, Atsuki Sasaki, Seiya Nishimura

Publication number: 20090317176Abstract: A connection end portion of a inner member is provided with engagement projections and a connection end portion of a stay is formed with reception grooves that are capable of axially receiving the engagement projections. When operation cable is axially inserted into a cylindrical support, the engagement projections are axially received in insertion grooves and are retained in terminal end positions thereof that are bent in a circumferential direction. When the stay is axially inserted into the cylindrical support in this condition, the engagement projections are axially received in the reception grooves and move to terminal end positions thereof that are bent in an opposite circumferential direction. As a result, the operation cable is positioned in an axial connection condition in which the operation cable is suspended in the stay.Type: ApplicationFiled: June 29, 2007Publication date: December 24, 2009Applicant: TOYOTA BOSHOKU KABUSHIKI KAISHAInventors: Toshihiro Shimizu, Atsuki Sasaki, Seiya Nishimura

Publication number: 20090121526Abstract: It is one object of the present invention to provide a control for moving a head rest in response to a signal from a sensor detecting a distance between the head rest and a head of a passenger, in which even if the head of the passenger moves within a predetermined range, the head rest can be prevented from moving depending on the motion of the head of the passenger so as to remove discomfort for the passenger. Therefore, the present invention has a construction as follows. A head rest control system in which a head rest of a seat of a vehicle is constructed to be moved back and forth by a head rest moving mechanism may include a sensor detecting a distance between the head rest and a head of a passenger, and a control device controllably actuating the head rest moving mechanism.Type: ApplicationFiled: December 6, 2005Publication date: May 14, 2009Inventors: Fumitoshi Akaike, Seiya Nishimura, Tomokazu Moriyama, Kiyoka Matsubayashi

Patent number: 7484797Abstract: A head rest of a vehicle seat may include a head support portion for supporting a head of a passenger, and a drive unit for moving the head support portion. The drive unit has a moving mechanism that is arranged and constructed to move the head support portion vertically and back and forth relative to the vehicle seat, a head detecting device provided to the head support portion so as to detect a clearance between the passenger head and the head support portion and to generate a control signal representative of the detected clearance, and a controller that can control the moving mechanism. The controller controls the moving mechanism so as to move the head support portion to a first proximity position in which the head detecting device may have a predetermined sensitivity relative to passenger head if the head support portion does not reach the first proximity position.Type: GrantFiled: December 27, 2005Date of Patent: February 3, 2009Assignees: Toyota Boshoku Kabushiki Kaisha, Fujikura Ltd.Inventors: Fumitoshi Akaike, Seiya Nishimura, Fumio Yajima, Nobumasa Misaki
