Patent number: 8182014Abstract: With a vehicle seat arranging structure, a second-row passenger-side seat may be placed in a rearward slide position by sliding the second-row passenger-side seat toward the rear of a vehicle by 150 millimeters so that the second-row passenger-side seat is closer to the rear of the vehicle than the second-row driver-side seat. In addition, each of the second-row driver-side seat and the second-row passenger-side seat may be placed in an obliquely-inward frontward-oriented position by swiveling each of the second-row driver-side seat and the second-row passenger-side seat from the frontward-oriented position 10 degrees inward in the vehicle-width direction. In this way, the sense of distance between the occupants seated in the second-row driver-side seat and the second-row passenger-side seat is reduced. As a result, it is possible to promote communication between these occupants (to make it easier for these occupants to communicate with each other).Type: GrantFiled: December 19, 2008Date of Patent: May 22, 2012Assignees: Toyota Jidosha Kabushiki Kaisha, The University of TokyoInventors: Teiji Mabuchi, Osamu Fujimoto, Makoto Itou, Kei Matsui, Yoshihiro Suda

Patent number: 8123272Abstract: A vehicle seat is taught that preferably include a seat cushion (10), a seat back (20) rotatably connected to the seat cushion via a reclining mechanism (30), front (40) and rear (46) legs removably connecting the seat cushion to a vehicle floor (66), a retracting link (50), an operating member capable of removing the front and rear legs from the floor, and a coupling link (54). The seat back can be rotated forwardly by unlocking the reclining mechanism, so as to be superimposed on the seat cushion. When the front and rear legs are removed from the floor, the seat can be moved from a use condition to a retracted condition depending on the motion of the retracting link. When the seat is moved from the use condition to the retracted condition, the coupling link rotates the front leg based on a displacement of the retracting link, thereby unlocking the reclining mechanism.Type: GrantFiled: September 5, 2007Date of Patent: February 28, 2012Assignees: Toyota Boshoku Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Makoto Ito, Yoshihiro Ooishi, Tomohiro Muramatsu, Osamu Fujimoto, Robert Day
