1. A bed having a head end and a foot end and comprising:
- a base framework,a mattress framework extending longitudinally from the head end to the foot end for supporting a mattress,an intermediate framework for supporting the mattress framework,tilting means for tilting the intermediate framework relative to the base framework, the tilting means comprising;
longitudinally spaced apart first and second main rams connected between the base framework and the intermediate framework, the first main ram being pivotally connected to one of the said frameworks, and the main rams being independently operable relative to each other for tilting the intermediate framework relative to the base framework, wherein the first main ram is pivotally connected to the said framework about a pair of spaced apart, transversely disposed first and second pivot axes, the first main ram being pivotally connected to the base framework by an elongated pivot member pivotally connected to the base framework about the first pivot axis and depending downwardly therefrom, the pivot member pivotally carrying a pivot frame about the second pivot axis, the first main ram being rigidly connected to the pivot frame.

Abstract
A bed comprises a base framework, an intermediate framework and a mattress framework which comprises a central frame, a head frame and a foot frame. Main rams connect the intermediate framework to the base framework for raising and lowering and tilting the intermediate framework relative to the base framework. The rams pivotally engage the intermediate framework by shafts. The ram is rigidly mounted to the main framework. A pivot frame pivotally mounts the ram about a pair of pivot axes relative to the base framework to accommodate tilting of the intermediate framework.
