a mechanism configured to control movement of the foot section relative to the seat section, the mechanism being configured to move between a first position wherein the foot section remains substantially horizontal when the seat section moves from the first position to the second position and a second position wherein the foot section deviates from being substantially horizontal when the seat section moves from the first position to the second position.
2. The patient support of claim 1 , wherein the mechanism includes a pair of first links pivotably coupled to the foot section of the deck and a pair of second links pivotably coupled to the intermediate frame and the first links, the first and second links are configured to move between a first position and second positions, when in the first position, the first and second links are rigidly coupled to provide a rigid link between the foot section and the intermediate frame so that the foot section remains substantially horizontal when the seat section moves from the first position to the second position, when in the second position, the first link is free to pivot relative to the second link so that the foot section deviates from being substantially horizontal when the seat section moves from the first position to the second position, the mechanism further includes a transversely extending link couple between the pairs of first and second links to coordinate movement thereof.
3. The patient support of claim 1 , wherein the mechanism includes a link, the intermediate frame includes a pin, the link includes a first end pivotably coupled to the foot section of the bed and a second link having a notch sized to receive the pin of the intermediate frame, the link is movable from a first position with the pin positioned in the notch and second position with the pin spaced apart from the notch, when the link is in the first position, the foot section remains substantially horizontal when the seat section moves from the first position to the second position, when the link is in the second position, the foot section deviates from being substantially horizontal when the seat section moves from the first position to the second position.
4. The patient support of claim 1 , wherein the mechanism has a first end and a second end and a distance between the first and second ends remains substantially constant when the mechanism is in the first position.
5. The patient support of claim 4 , wherein the mechanism includes a linear actuator having a first length that remains substantially constant when the mechanism is in the second position.
6. The patient support of claim 4 , wherein the mechanism includes first and second links pivotably coupled together when the mechanism is in the second position.
7. The patient support of claim 1 , further comprising a plurality of lift arms configured to raise and lower the intermediate frame relative to the base frame, the foot section remains substantially parallel to the intermediate frame when mechanism is in the first position and the seat section moves to the second position.
8. A patient support comprising
a base frame,
an intermediate frame supported by the base frame,
a deck supported by the intermediate frame, the deck including a seat section pivotable relative to the frame to move between first and second positions and a foot section pivotable relative to the seat section to move between first and second positions, and
a linkage having a first end and a second end coupled to the foot section of the deck, the linkage having a first configuration wherein a distance between the first and second ends remains substantially constant during movement of the seat section between the first and second positions and a second configuration wherein the distance substantially decreases during movement of the seat section between the first and second positions.
9. The patient support of claim 8 , wherein the linkage includes a first link pivotably coupled to the foot section of the deck, and a second link pivotably coupled to the first link.
10. The patient support of claim 9 , wherein the second link is pivotably coupled to the intermediate frame.
11. The patient support of claim 8 , wherein the foot section has an adjustable length.
12. The patient support of claim 8 , wherein the linkage has an adjustable length.
13. The patient support of claim 12 , wherein the linkage includes telescoping members.
14. The patient support of claim 8 , further comprising lift arms configured to raise and lower the intermediate frame relative to the base frame, the foot section remains substantially parallel to the intermediate frame when the linkage is in the first configuration.
15. A patient support comprising
a base frame,
an intermediate frame supported by the base frame,
a deck supported by the intermediate frame, the deck including a head section, a seat section adjoining contiguous with the head section, substantially all of the seat section being pivotable relative to the intermediate frame to move between first and second positions, and a foot section pivotable relative to the seat section, the seat section and foot section cooperating to define an angle when the seat section is in the second position, and
means for selecting the angle defined between the seat and foot section when the seat section is in the second position.
16. The patient support of claim 15 , wherein the selecting means includes a linkage having first and second links.
17. The patient support of claim 15 , wherein the selecting means includes a linear actuator.
18. The patient support of claim 15 , wherein the selecting means extends to the foot section.
19. The patient support of claim 18 , wherein the selecting means extends to the intermediate frame.
20. The patient support of claim 19 , further comprising means for supporting the patient on the deck, means for blocking egress of a patient from the support means, and means for controlling movement of the deck, wherein the control means includes a pendent controller that removably couples to the blocking means and foot operated control means supported by the base frame.
