ABSTRACT:
This invention relates to a vehicle seat of the type in which a seat part is supported and guided for upward and downward movement relative to a base part by a spring suspension.
In order to avoid loss of contact between the feet of the seat occupant and control pedals of the vehicle, the suspension includes linkages connecting the seat part to the base part for relative movement such that the seat occupant's ankles remain stationary whereas his knees swing about an axis through his ankles.
