Abstract
A patient support apparatus includes a frame and a deck carried on the frame. The deck includes longitudinally-spaced apart and transversely-extending back, seat, thigh and foot sections, with at least the back, thigh and foot sections articulated relative to the frame. A back section drive is coupled to the back section to raise and lower the back section. A thigh section drive coupled to the back section and the thigh section to initially raise and then lower the thigh section as the back section is raised.

A patient support apparatus comprising:
- a frame,
- a deck coupled to the frame, the deck including a back section, a seat section and a thigh section, the back, seat and thigh sections being longitudinally spaced apart and transversely extending with at least the back and thigh sections being articulated relative to the frame,
- a back section drive,
- a first thigh section drive, and
- a second thigh section drive,
- the back section drive being coupled to the back section to move the back section between a lowered and a raised position through an intermediate position therebetween,
- the first thigh section drive being coupled to the back section such that the thigh section moves from a lowered position to a raised position as the back section moves from the lowered position to the intermediate position and such that the thigh section moves from the raised position to the lowered position as the back section moves from the intermediate position to the raised position, the first thigh section drive comprising a track coupled to the frame, and a track-engaging member movable along the track and coupled to the thigh section and coupled t the back section, and
- the second thigh section drive being coupled to the thigh section and being operable independent of the back section drive to raise and lower the thigh section.

A patient support apparatus comprising:
- a frame,
- a deck coupled to the frame, the deck including a back section, a seat section and a thigh section, the back, seat and thigh sections being longitudinally spaced apart and transversely extending with at least the back and thigh sections being articulated relative to the frame,
- a back section drive,
- a first thigh section drive, and
- a second thigh section drive,
- the back section drive being coupled to the back section to move the back section between a lowered position and a raised position through an intermediate position therebetween,
- the first thigh section drive being coupled to the back section such that the thigh section moves from a lowered position to a raised position as the back section moves from the lowered position to the intermediate position and such that the thigh section moves from the raised position to the lowered position as the back section moves from the intermediate position to the raise position, the first thigh section drive including a linkage configured to be coupled to the thigh section and a spring cutch coupling back section to the linkage, the spring clutch including a housing, a coil gripping spring received inside the housing and a connecting rod, the spring clutch being lockable so that the gripping spring constricts around the connecting rod preventing the connecting rod from sliding relative to the gripping spring and the clutch housing to couple the back section to the linkage so that the thigh section is initially raised and then lowered as the back section is raised, the spring clutch being releasable so that the gripping spring loosens its grip on the connecting rod allowing the connecting rod to slide relative to the gripping spring and the clutch housing to decouple the back section from he linkage so that the back section can be raised without also raising the thigh section, and
- the second thigh/section drive being coupled to the thigh section and being operable independent of the back section drive to raise and lower the thigh section.

- a back section drive coupled to the back section to raise and lower the back section,
- a first thigh section drive coupled to the back section and the thigh section to initially raise and then lower the thigh section as the back section is raised, the first thigh section drive comprising a track coupled to the frame, and a track-engaging member movable along the track and coupled to the thigh section and coupled to the back section, and
- a second thigh section drive coupled to the thigh section and operable independent of the back section drive to raise and lower the thigh section.
