Patent number: 9376137Abstract: A steering device includes: a steering shaft and a column jacket that are telescopically adjustable in an axial direction; a lock plate provided with a plurality of holes; a lock mechanism that moves a tooth such that the tooth advances to the lock plate to be engaged with one of the holes, and retreats from the lock plate to be disengaged from the hole. The lock plate includes a bent portion as a stopper at an end portion of the lock plate in the axial direction, and the stopper restricts a movement of an upper jacket relative to a lower jacket in the axial direction by abutting on the lock mechanism in the axial direction when the steering shaft and the column jacket is telescopically adjusted.Type: GrantFiled: March 23, 2015Date of Patent: June 28, 2016Assignees: JTEKT CORPORATION, Toyota Jidosha Kabushiki Kaisha, Fuji Kiko Co., Ltd.Inventors: Yoshihito Yoshihara, Tomonori Sugiura, Yuji Takahashi, Atsumune Nagatani, Tatsuro Kubota, Shigeru Hoshino, Yota Uesaka

Publication number: 20160176435Abstract: A resin pin which is passed through a first resin-pin passing hole of a first plate, and a second resin-pin passing hole of a second plate to couple the second plate to a predetermined position of the first plate is sheared in a secondary collision, and causes the second plate to release from the predetermined position in a column movement direction. A slide plate which extends along the upper surface of the first plate has a resin-pin visual check hole. A highly hard collar is received by the second plate, placed in the first resin-pin passing hole, and fitted to a shaft portion of the resin pin. In the resin pin, axial elastic projections which apply a pressing and urging force to the slide plate are disposed at positions avoiding a range where, in a secondary collision, the resin-pin visual check hole is passed in the column movement direction.Type: ApplicationFiled: July 17, 2014Publication date: June 23, 2016Applicants: JTEKT CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Eiji TANAKA, Susumu MAGAKI, Shigeru HOSHINO, Shunsuke NUNOMURA

Patent number: 9346481Abstract: A steering column device including a first bracket for supporting a column tube that supports a steering shaft, a second bracket coupled to the first bracket and assembled onto a vehicle body, and a disengaging mechanism provided on the second bracket that allows the column tube to be disengaged from the vehicle body forward along a column axis direction under a set load when a secondary impact is caused with a collision of a vehicle. The first bracket and the second bracket are coupled to each other through an intermediation of a coupling mechanism in a relatively rotatable manner, and a rotation center of relative rotation intersects an axis center of the steering shaft. The first bracket and the second bracket perform relative rotation when an external force exceeding a predetermined value is applied to the disengaging mechanism along the column axis direction before the first bracket, the second bracket, the disengaging mechanism are assembled onto the vehicle body.Type: GrantFiled: July 23, 2012Date of Patent: May 24, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Shigeru Hoshino
