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.

[0002] This application claims priority to US Provisional Patent Application No. 60 / 366,965, filed March 22,2002. technical field

[0003] The present invention relates to a suspension for a seat, and more particularly to a seat suspension which varies the preload, spring rate and damping ratio of the suspension in proportion to the weight of the seat occupant. Background technique

[0004] In order for an operator to effectively control a machine, the seat that interfaces the operator with the machine must be able to comfortably support the operator for extended periods of time. In order to provide comfortable support for the operator, many different seat suspension designs have been developed in recent years. In most designs, the seat suspension is manufactured to suit the operator by using various suspension mechanisms or systems within the seat so that the amount of resistance or support provided and the vertical positio...
