ABSTRACT:
A mattress suspension system is attachable to a horizontally oriented deck of a vehicle for substantially reducing the amplitude of fore-and-aft excursions and of up and down excursions which are transmitted by the vehicle to an individual reclining on a mattress positioned above the suspension system. The suspension system includes a lower frame which can be attached to the vehicle deck. An intermediate frame is positioned above the lower frame and includes a plurality of rollers on each end thereof. The rollers are movably fitted within a horizontally oriented roller guide which is coupled to each end of the lower frame. Fore-and-aft movement of the intermediate frame with respect to the lower frame is permitted by the rolling movement of the rollers within the roller guides. An upper frame is positioned between the mattress and the intermediate frame. A damper system is coupled between the upper and intermediate frames and serves to maintain the upper frame above and in a fixed fore-and-aft position with respect to the intermediate frame. The damper also permits damped up and down excursions between the upper frame and the intermediate frame in response to up and down excursions of the vehicle.
