Patent number: 10160069Abstract: A headrest stay is manufactured with a metal round pipe having a predetermined length and a predetermined thickness by performing a boring process on the metal round pipe by a cutting length of 5 mm or more from each of both distal ends of the metal round pipe to form a thin-walled portion that is thinner than the predetermined thickness; forming each of the distal ends of the metal round pipe into an curved chamfered shape having a radius of 5 mm or more by inserting each of the distal ends of the metal round pipe into a cylindrical hole; and bending the metal round pipe to have a shape of the headrest stay.Type: GrantFiled: March 9, 2016Date of Patent: December 25, 2018Assignees: TOYOTA BOSHOKU KABUSHIKI KAISHA, TOKAI CHEMICAL INDUSTRIES, LTD.Inventors: Hiroyuki Nasu, Akihide Ozaki, Koki Uemura

Patent number: 9782007Abstract: A headrest support having a hollow cylindrical shape and into which a headrest stay is inserted, is inserted into a bracket that has a hollow cylindrical shape and is fixed to a seat back frame. A protrusion, a tip end of which is a pivot center of the headrest support, formed such that a protrusion amount thereof increases in response to insertion of the headrest stay, is provided on an outer peripheral surface of this headrest support.Type: GrantFiled: July 11, 2014Date of Patent: October 10, 2017Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, TOYOTA BOSHOKU KABUSHIKI KAISHAInventors: Gen Takahashi, Akihide Ozaki

Patent number: 9545862Abstract: A headrest is mounted to a seat back by inserting a support into a support hole of a holder and inserting a stay of the headrest into to stay hole of the support inserted into the support hole of the holder. A gap occupying part provided in the support moves between an advanced position at which the gap occupying part protrudes from an outer wall of the support and is capable of touching an inner surface of the support hole, and a retracted position at which the gap occupying part is retracted to an inner side of the stay hole from the advanced position. The gap occupying part moves toward the retracted position from the advanced position when the support is inserted into the support hole, and moves toward the advanced position when the stay is inserted into the stay hole.Type: GrantFiled: April 23, 2015Date of Patent: January 17, 2017Assignee: TOYOTA BOSHOKU KABUSHIKI KAISHAInventors: Hidekazu Kitou, Akihide Ozaki

Patent number: 9403456Abstract: A headrest support structure of a conveyance seat includes: an upper frame that is provided with a pair of fitting holes and that constitutes a back frame; and a pair of cylindrical headrest holders, each of which fits in one of the pair of fitting holes to be fixed to the upper frame. A transverse cross-section of a fitting portion of each headrest holder fitting in the corresponding fitting hole has an asymmetric shape about a fitting axis parallel to a fitting direction in which the headrest holder fits in the fitting hole, the transverse cross-section being a cross-section in a direction orthogonal to the fitting axis. The pair of fitting holes is formed such that each headrest holder is allowed to fit in only one of the pair of fitting holes provided at a position set as a fixing position of the headrest holder.Type: GrantFiled: September 26, 2014Date of Patent: August 2, 2016Assignee: TOYOTA BOSHOKU KABUSHIKI KAISHAInventor: Akihide Ozaki

Patent number: 8760835Abstract: To include a serial member, a pair of first electrodes sandwiching the serial member, a pair of second electrodes arranged on both outer sides of the first electrodes in a stacking direction, a plurality of insulating clamp members, and a wedge-shaped member tapered in the stacking direction. An annular member that presses the wedge-shaped member is provided on an axial-direction inner end surface of an outer circumferential edge of the second electrode, and the wedge-shaped member is pressed by the annular member by a leading edge portion of a bolt inserted from an axial-direction inner end surface of the annular member being tightened in the second electrode, thereby pressing an axial-direction outer surface of the insulating clamp member.Type: GrantFiled: November 7, 2012Date of Patent: June 24, 2014Assignee: Mitsubishi Electric CorporationInventors: Akihide Ozaki, Hiroki Saito, Koichi Akaso
