Abstract
A suspension for a seat that varies the preload, spring rate and damping rate of the suspension in direct proportion to the suspended weight of an occupant of the seat to provide the same effective vibration isolation for any occupant. The suspension includes an actuating mechanism engaged with a first spring and a pivotal transfer link that is engaged with a second spring and a non-adjustable rate damper that are each fixedly attached to the seat opposite the transfer link. The transfer link is engaged with a weight adjustment mechanism which operates to adjust the position of a pivot pin for the transfer link with respect to the transfer link, such that the preload, spring rate and damping rate of the suspension are adjusted in proportion to the weight of the occupant of the seat to provide similar ride dynamics to any occupant of the seat.
