Vehicle seat device
First Claim
1. A vehicle seat device comprising:
- flank brackets adapted to support a seat cushion and rotatably coupled at rear portions to floor attached rear brackets;
rotational links rotatably supported at center portions on front portions of the flank brackets;
a front drive device for relatively rotating the rotational links relative to the flank brackets;
cushion frames for the seat cushion, having rear end portions rotatably coupled to center portions of the flank brackets and having front end portions coupled to second joint portions ahead of the center portions of the rotational links to be restricted from movement in a vertical direction relative to the rotational links and to be relatively movable in a forward-rearward direction; and
floor attached front brackets having one end coupled to first joint portions behind the center portions of the rotational links to be restricted from movement in the vertical direction relative to the rotational links and to be relatively movable in the forward-rearward direction.

Abstract
A vehicle seat device is designed to perform tilt adjustment of a seat cushion in a construction which is high in rigidity, downsized and high in the quality of external appearance. The device comprises rotational links; floor attached front brackets and front swing links which make couplings between first joint portions of the rotational links and upper rails; flank brackets coupled to the rotational links at front portion thereof; floor attached rear brackets and rear swing links which make couplings between rear portions of the flank brackets and the upper rails; a front drive device secured to one of the flank brackets for rotationally driving the rotational links; and cushion frames coupled to the flank brackets and second joint portions of the rotational links respectively at rear portions and front portions thereof. The second joint portions and the cushion frames are coupled to respective both ends of cushion frame swing links.
