A person support apparatus comprising a person support frame (3) having two sides, a head end and a foot end, and a support assembly for supporting the person support surface and moving it relative to a floor surface. The support assembly comprises a lower frame including a pair of longitudinal lower frame elements (35) running substantially parallel to the sides of the person support frame (3), the lower frame having floor engaging elements (14) for supporting the frame above the floor. The support assembly also includes two leg assemblies (6f, 6h). Each leg assembly includes a leg element having a first end pivotally coupled to the person support surface and a second end pivotally coupled to a longitudinal lower frame element. The lower end of the foot end leg element (7f) is pivotally connected to the longitudinal lower frame element via an extension piece (42) having a first end and a second end. The first end portion of the extension piece (43) is pivotally connected to the longitudinal lower frame element and the second end of the leg element is pivotally connected to a second end portion portion of the extension piece (43). |
