An articulating mechanism includes a drive pivotally connected at a first end to the upper body section about a first pivot axis substantially perpendicular to the longitudinal axis of the bed and pivotally connected at a second end to the base frame about a second pivot axis parallel to the first pivot axis for translating the upper body section relative to the base frame, and a link pivotally connected at a first end to the upper body section about the first pivot axis and pivotally connected at a second end to the base frame about a third pivot axis parallel to the first pivot axis such that translation of the upper body section relative to the base frame results in tilting of the upper body section.
