  • Patent number: 7040702
    Abstract: 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).

  • Patent number: 6513873
    Abstract: 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.

  • Patent number: 6293603
    Abstract: In a vehicular seat 10A in which a link 15 which is rotatably fixed to a floor 9 is connected to a seat frame 21 at one end thereof for guiding the vehicular seat 10A for movement from an in-use state to a received state and vice versa, a rotation restraining member 17 is provided in such a manner as to extend between the floor 9 and the seat frame 21 for restraining the vehicular seat 10A, which has reached the received state from the in-use state, from further rotating about the link 15 by virtue of the action of inertia.

  • Patent number: 6149241
    Abstract: A vehicular seat includes an upper rail fixed to a seat cushion, a lower rail attached to a vehicle body side and slidably engagable with the upper rail so as to slide the seat cushion, an angle adjusting mechanism provided on a side of the seat cushion, for adjusting the angle of a seat back; and a cover attached to the angle adjusting mechanism. Folded portions are formed at ends of the cover for covering ends of the lower rail which are left protruding from the upper rail when the seat cushion is slid.
