1. A seat position control mechanism for a vehicle seat assembly having a substantially horizontal seat and a normally upright backrest pivotable relative to the seat for forward tilting movement, the control mechanism comprising:

  • stationary guides having a plurality of spaced latch engaging means and fixedly attached to the vehicle floor under the seat;

    slide members slidable on said stationary guides and attached to the seat;

    an elongate member disposed parallel with one of said stationary guides and an associated slide member and having first and second latch engaging apertures therein, each being arranged in registry with one of said latch engaging means of said stationary guide;

    a first spring-loaded latch on said elongate member and normally engaged with said first aperture and one of said latch engaging means of said stationary guide;

    a second spring-loaded latch on said slide member and normally engaged with said second aperture of said elongate member and another latch engaging means of said stationary guide;

    a manual control shaft axially rotatably supported by the slide member and engageable with said first and second latches to cause the same to disengage from the respective latch engaging means and said latch engaging apertures when said control shaft is manually turned, the engagement of said control shaft with said first latch being such that said elongate member is movable with said slide member; and

    means for connecting the backrest with said second latch in such manner that upon the forward tilting movement of the backrest said second latch is disengaged from said another latch engaging means and said second aperture to thereby allow said slide member to be moved forward and then backward to the position determined by the engagement of said first latch with said first latch engaging aperture and said one of the latch engaging means of said stationary guide, and at this position said second latch is engaged in said second aperature and said another latch engaging means.
