<p>A patient support apparatus (20) comprises a frame (26), at least one drop rail (66) coupled to the frame and tiltable relative to the frame (26), a seat section (44) supported by the at least one drop rail (66) to tilt therewith, a thigh section (46) coupled to the seat section (44), a head section (42) coupled to the frame (26) and coupled to the at least one drop rail (66), and a linkage (400) coupled to the head section (42) and coupled to the thigh section (46). Raising and lowering of the head section (42) results in tilting of the at least one drop rail (66) relative to the frame (26). The linkage (400) has a first mode of operation in which the seat (44) and thigh sections (46) remain substantially parallel as the at least one drop rail (66) tilts. The linkage (400) has a second mode of operation in which the thigh section (46) tilts relative to the seat section (44) as the at least one drop rail (66) tilts.</p> |
