METHOD AND APPARATUS FOR A SEAT SUSPENSION SYSTEM

摘要

A method and apparatus for an adaptive, multi-axis suspension system providing both coarse and fine suspension for a passenger seat. Coarse suspension control is provided to maintain the passenger seat and passenger within a selected position regardless of the weight of the passenger seat and the passenger. Fine suspension control is provided by monitoring and analyzing vibration characteristics in time and/or frequency domains to determine a variable amount of damper resistance to be exerted by a magnetorheological (MR) device. A nominal damper resistance of the MR device is selected based on the combined weight of the passenger seat and the passenger.

1. A seat suspension system, comprising:
a payload; a first pneumatic device; and a first damper having a damper resistance based, at least in part, on first information indicative of a weight of the payload.
