1. A vehicle seat with a height adjustable seat bottom, comprising:
- a pair of side frames which constitutes left and right frames of the seat bottom;
left and right rear links pivotally connected to rear portions of the side frames, respectively;
left and right front links disposed frontwardly of the rear links and pivotally connected to the side frames, respectively;
a link support member disposed under the side frames and configured to support the rear links and the front links in a manner that renders the links pivotable, thereby forming a four-bar linkage with the side frames, the rear links and the front links; and
an operation unit including an operation member configured to be operated to make a rotational motion which actuates the four-bar linkage for adjustment of a height of the seat bottom,wherein the operation unit includes an output gear configured to be rotatable coaxially with the operation member provided at one of the pair of side frames, andwherein the front links include an input gear configured to engage with the output gear, such that rotation of the output gear causes the front links to pivot.
