Abstract
There is provided a vehicular seat capable of achieving smooth sliding motion. A first slider is formed by connecting center rails, on an outside of inner rails to each other by brackets, and a second slider, having a seat, is formed by connecting outer rails to each other by a bracket. A drive mechanism has ends of a driving chain, set around a drive sprocket, fixed to the bracket of the first slider after being returned by sprockets of the inner rail. A sending-out mechanism, which moves the second slider beyond the first slider when the first slider is moved beyond a swivel upper, is formed by fixing a sending-out chain, which is fixed relative to the inner rail and to the bracket of the outer rail after being returned by a sprocket at a front end of the center rail.

A sliding vehicular seat comprising
- a base for mounting in a vehicle;
- a first frame having a first frame end and a second frame end and slidably supported on said base so as to extend said first frame end in an extending direction from a first frame first position proximate said base to a first frame second position extended from said base;
- a second frame having a seat and slidably supported on said first frame so as to extend said second frame end in the extending direction from a second frame first position retracted on said first frame to a second frame second position extended from said first frame and said base;
- a first drive mechanism for extending and retracting said first frame relative to said base between said first frame first position and said first frame second position extended from said base, said first drive mechanism having a first driven member extending and retracting said first frame relative to said base;
- and
- a second drive mechanism for extending and retracting said second frame relative to said base and said first frame between said second frame first position and said second frame second position extended from said base, said second drive mechanism having a second driven member connected to said second frame to apply force to said second frame to extend said second frame relative to said first frame to said second frame second position, said second driven member being independent of said first driven member and driven by displacement of said first frame relative said base.

- a second drive mechanism for extending and retracting said second frame relative to said base and said first frame between said second frame first position and said second frame second position extended from said base, said second driven member being driven by displacement of said first frame relative said base;
- a seat leg for supporting said seat on said second frame;
- a footrest;
- a support bar structure for supporting said footrest extendable from the seat leg so as to be capable of freely being pulled out and pushed in;
- a handle provided at one side portion of said footrest;
- said support bar structure includes:
- a first bar extending from the one side portion of said footrest at which said handle is provided;
- and
- a second bar extending from another side portion of said footrest;
- said seat leg having:
- a first holding portion for holding said first bar so as to be capable of freely being pulled out;
- and
- a second holding portion for holding said second bar so as to be capable of freely being pulled out;
- and
- a slidable contact resistance between said second bar and said second holding portion being lower than a slidable contact resistance between said first bar and said first holding portion.
