An articulating mechanism (38) according to the present invention includes a drive (50) pivotally connected at a first end (52) to the upper body section (42) about a first pivot axis (54) substantially perpendicular to the longitudinal axis (26) of the bed (10) and pivotally connected at a second end (58) to the base frame (12) about a second pivot axis (60) parallel to the first pivot axis (54) for translating the upper body section (42) relative to the base frame (12), and a link (80) pivotally connected at a first end (82) to the upper body section (42) about the first pivot axis (54) and pivotally connected at a second end (88) to the base frame (12) about a third pivot axis (90) parallel to the first pivot axis (54) such that translation of the upper body section (42) relative to the base frame (12) results in tilting of the upper body section (42). |
