ABSTRACT:
The invention relates to a suspension seat for a vehicle.
The vehicle suspension seat has a back rest guided for vertical movement relative to a base part, a seat rest hinged to the back rest and guided for movement such that the body of the seat occupant swings about an axis through his ankles. An armrest is mounted for movement relative to the back rest and seat rest, so as to minimize movement of the seat occupant's arm relative to a steering wheel, by pivotally supporting the armrest about the instantaneous centers of rotation of the armrest relative to two parts of the seat which move pivotally with respect to each other in response to vertical movement of the back rest.
