  • Patent number: 7712816
    Abstract: A movable floor device for a vehicle, which comprises a movable board disposed beneath feet of an occupant seated in an occupant seat, a drive source disposed below the occupant seat, and a driving-force transmission mechanism adapted, according to a driving force of the drive source, to input a force directed in a selected one of frontward and rearward directions of a vehicle body, into a rear portion of the movable board. The movable board is supported in such a manner as to be selectively displaced upwardly and downwardly in response to respective ones of the frontward and rearward forces input from the driving-force transmission mechanism. The movable floor apparatus of the present invention makes it possible to allow a lowermost height position of a movable board to be set at a lower level so as to cope with various seating postures with enhanced flexibility.

  • Patent number: 7533936
    Abstract: A vehicle seat assembly comprises a coupling member 12 coupling a front end of a seat-cushion frame 2 to an upper rail 11, a rear link member 23 provided in a rear end of the seat-cushion frame 2, and a support member 24 provided on the side of a vehicle body to support the rear link member 23. The rear link member 23 includes a pivoted portion 26 pivotally supported by the upper rail 11, a coupled portion 28 coupled to the rear end of the seat-cushion frame 2, and an engaged portion engaged with the support member 24. The support member 24 includes a sliding drive portion (sliding groove 33) which slidably supports the engaged portion of the rear link member 23 to allow the rear link member 23 to be swingingly displaced in conjunction with a longitudinal movement of the seat-cushion frame 2, so as to move the coupled portion 28 in an upward/downward direction to drivingly lift and lower the rear end of the seat-cushion frame 2.
