Publication number: 20220194272Abstract: A vehicle seat that can suppress damage to an on-board object is provided. In each side frame of a cushion frame, an eccentric portion is eccentric outward in a right-left direction with respect to a base portion, and in each side frame of a back frame, an eccentric portion is eccentric inward in the right-left direction with respect to a base portion. Thus, when the load at the time of rear collision acts, each side frame of the cushion frame easily becomes deformed outward in the right-left direction, and each side frame of the back frame easily becomes deformed inward in the right-left direction. Accordingly, the deformation direction of each side frame of the cushion frame and the deformation direction of each side frame of the back frame can be easily made opposite to each other, and the deformations of the respective side frames and can be inhibited.Type: ApplicationFiled: January 24, 2020Publication date: June 23, 2022Applicants: TACHI-S CO., LTD., Mitsubishi Jidousha Kogyo Kabushiki KaishaInventors: Yoshikazu Kijima, Akira Ogiso, Yutaka Yasuda

Patent number: 8939511Abstract: A first and a second surface of a latch for a seat permit sliding passage of the latch relative to a front leg of a striker, upon contact of the front leg with either of the first and second surfaces. A third surface in a containing space of the latch stops the latch by contacting the front leg. The third surface is arranged such that a rear leg of the striker is brought in alignment with a lock groove of the latch upon contact of the front leg with the third surface. The latch can be guided along the second surface when the second surface contacts the front leg, so that the second surface slides on and past the front leg. By continuously unfolding the seat back upwards until the third surface contacts the front leg, the seat back can be set to a design reference position.Type: GrantFiled: February 15, 2011Date of Patent: January 27, 2015Assignees: Mitsubishi Jidousha Kogyo Kabushiki Kaisha, Mitsui Kinzoku Act Corporation, Tachi-S Co., Ltd.Inventors: Sanji Majima, Ken Kuroiwa, Akira Ogiso, Kiyohiko Kamata, Hiroyuki Nozaki
