Patent number: 10640013Abstract: The present invention has an object to provide a seat for vehicles in which walk-in operation can be cancelled by simple operation. A seat for vehicles includes: a mechanism to shift a seat cushion (2) from a seating position to an escape position by operation of an operation part (9); and a walk-in cancel mechanism (400) for cancelling walk-in operation which restrains a seat back (3) from rotating to a fully tilted-down position of the seat back (3) when the seat cushion (2) is shifted from the seating position to the escape position and the seat back (3) is rotated to a middle tilted position, and also switches a slide rail device in a locked state to an unlocked state, in which the walk-in cancel mechanism (400) is automatically operated in conjunction with operation of the operation part (9).Type: GrantFiled: April 19, 2016Date of Patent: May 5, 2020Assignee: TACHI-S CO., LTD.Inventors: Kazuya Imayou, Toshiki Igarashi, Yayoi Hirano, Shunsuke Yamaoka

Patent number: 9511689Abstract: A seating apparatus for a vehicle, in which a seat cushion supported on the vehicle body by a link member can be flipped up toward the front of the vehicle from a use position and which includes a locking mechanism that operates only when the seat cushion is acted upon by an inertial force greater than a predetermined force in the longitudinal direction of the vehicle, to temporarily prevent the seat cushion from flipping up. The locking mechanism includes a locking plate supported on the seat cushion and rockable in the longitudinal direction of the vehicle between a normal position and a rocked position, and a spring for urging the locking plate toward the normal position. The locking plate locks the seat cushion to the link member when it is moved inertially to the rocked position against the force of the spring, to prevent the seat cushion from flipping up, and the locking plate unlocks the seat cushion when it is located in the normal position.Type: GrantFiled: March 26, 2013Date of Patent: December 6, 2016Assignees: Mitsubishi Jidosha Kogyo Kabushiki Kaisha, Tachi-S Co., Ltd.Inventors: Yohei Mabashi, Yoshiyuki Shimomura, Shigeya Fujino, Katsuhiko Sasaki, Kazuya Imayou, Toshiki Igarashi, Masao Ishihara

Patent number: 9315132Abstract: A part of the planar member, which is defined by the slits and extends over the center groove made in a seat pad, serves as a bridge part. As the sewn part of a trim cover is pulled into the groove, the bridge part is pressed onto the sewn part of the trim cover and pulled into the groove, together with the sewn part, and is bend in the form like letter U and held in the groove. The groove defines a through hole penetrating the seat pad at the bridge part of the planar member. The bridge part is not pressed onto the bottom of the groove even if the seat pad undergoes compressive deformation and is pressed down in the groove, because the groove has no bottom at some parts.Type: GrantFiled: April 7, 2014Date of Patent: April 19, 2016Assignee: TACHI-S CO., LTDInventors: Yohei Mabashi, Makoto Miyabata, Mutsuo Muramatsu, Kenichi Sugimoto, Toshiki Igarashi, Masaaki Honda, Kazuya Imayou, Yayoi Hirano

Patent number: 6722740Abstract: A forward and backward inclination adjustment device for a headrest provided with a headrest body frame section and a generally inverted-U-shaped frame having a horizontal columnar frame section and a pair of headrest stay portions. In the forward and backward inclination adjustment device, a leaf spring element of generally “U” shape is fixed to the headrest body frame, while embarcingly holding the horizontal columnar frame section, and a plurality of discrete flat surfaces are formed in the circumferential surface of the horizontal columnar frame section. Thus, each time a user inclines the headrest body frame section forwardly and backwardly relative to the headrest stay portions, the leaf spring element is contacted with one of the discrete flat surfaces, thereby imparting a clicking stepwise touch to a hand of the user.Type: GrantFiled: June 12, 2003Date of Patent: April 20, 2004Assignee: Tachi-S Co., Ltd.Inventors: Kazuya Imayou, Tokuyuki Shimizu
