Patent number: 7040702Abstract: A tip-up vehicle seat comprises a seat back (11) attached to a vehicle body, a seat bottom (14) displaceable between a retracted position and a available position, a leg member (17) displaceable between a retracted position and a support position, a lock mechanism (18) arranged to hold the seat bottom at the retracted position. The lock mechanism (18) is connected to the leg member (17) through a wire cable (43) so that the lock mechanism (18) is unlocked by rotational movement of the leg member (17) from the retracted position toward the support position to release the restriction to the seat bottom (14).Type: GrantFiled: June 10, 2002Date of Patent: May 9, 2006Assignees: TS Tech Co., Ltd., Honda Giken Kogyo Kabushiki KaishaInventors: Takurou Yamada, Masayuki Takakura, Takahiro Ito, Seiji Waku

Patent number: 6513873Abstract: When no child seat is attached to a folding adult seat of an automotive vehicle, the seat bottom of the adult seat is retained in a first locked state relative to the floor of the vehicle by means of a first locking mechanism alone. When an ISO-FIX child seat is attached to the adult seat, the seat bottom of the adult seat is retained in an additional locked state relative to the vehicle floor by a second locking mechanism that automatically locks the seat bottom by being operated on by part of the child seat as the child seat is moved toward and engaged with the seat. In this case, the second locking mechanism that is directly operated on by the attached child seat is constructed to perform a primary seat-bottom locking function to lock the seat bottom relative to the vehicle floor, while the first locking mechanism performs an auxiliary seat-bottom locking function.Type: GrantFiled: September 6, 2001Date of Patent: February 4, 2003Assignee: Honda Giken KogyolKabushiki KaishaInventors: Toshihiko Tsuda, Seiji Waku
