Patent number: 9061613Abstract: A seat back pad 70 has a groove 73 for tucking a skin material therein, formed at borders between a central portion 71 and side portions 72. A hole (slot hole 74) is formed in a bottom of the groove 73 along the groove 73. A tuck-in wire 76 for tucking the skin material in includes a plurality of tuck-in portions 76A provided along the groove 73, and a connecting portion (detour portion 76B) detouring around the hole and connecting the tuck-in portions 76A. With this configuration, when an upper body of an occupant P subsides into a seat back S2 in a rear-end collision of a vehicle, the central portion 71, defined by the groove 73 as a border, is easily and sufficiently moved rearward relative to the left and right side portions 72. Furthermore, the tuck-in wire 76 is not exposed through the hole, and thus adhesion between the seat back pad 70 and the tuck-in wire 76 can be improved.Type: GrantFiled: January 7, 2015Date of Patent: June 23, 2015Assignee: TS TECH CO., LTD.Inventors: Takamasa Adachi, Tsutomu Matsuzaki, Masayuki Yamaguchi

Publication number: 20130119724Abstract: Provided is a vehicle seat by which an impact of rear end collision is reduced and of which peripheral structure of a side frame is simplified. A vehicle seat includes: a seat back frame which includes side portions positioned at the sides thereof, a pressure receiving member which is jointed to the seat back frame through joint members and supports an occupant, and an impact reduction member which is disposed on at least one of the side portions to engage with the joint member and to move by a predetermined amount of impact load applied to the pressure receiving member so that the pressure receiving member is caused to move rearward; in which the side portion includes a convex portion protruding in the movement range of the impact reduction member, and the impact reduction member abuts against the convex portion so that the movement of the impact reduction member is prevented.Type: ApplicationFiled: July 21, 2011Publication date: May 16, 2013Applicant: TS Tech Co., Ltd.Inventors: Takamasa Adachi, Hiroyuki Kaku, Takayuki Inoue, Yutaka Kizawa, Akimitsu Kurihara
