A vehicle seat apparatus comprising:
- a cushion body provided on a frame member;
- a seat cushion, a seating surface of which is formed by the cushion body;
- a gear member rotatably supported at the frame member;
- a driving mechanism supported at the frame member and connected to the gear member so as to rotate the gear member;
- an arm swingably supported at the frame member and connected to a front-end portion of the cushion body;
- and
- a link mechanism comprising:
- a first bracket rotatably supported at the gear member around a shaft extended in a direction of a rotation center of the gear member;
- a second bracket rotatably supported at the first bracket around a shaft extended substantially perpendicular to a rotation center of the first bracket;
- and
- a link bracket, a first end of which is rotatably supported at the second bracket around a shaft extended substantially perpendicular to a rotation center of the second bracket, and a second end of which is connected to the arm, wherein
- the arm is connected to the gear member through the link mechanism, and
- with an up-and-down operation of the front-end portion of the cushion body relative to the frame member by means of a swing of the arm, a length of the seating surface is variable in a longitudinal direction.
