Person support apparatuses with selectively coupled foot sections
Person support apparatuses are disclosed. In one embodiment, a person support apparatus comprises a base frame and a primary support frame supported on the base frame. A carriage is freely translatable at least between a head end of the primary support frame and a foot end of the primary support frame. A support surface is supported on the carriage such that the support surface translates with the carriage. The support surface includes a support section which is collapsible in a length direction of the support surface. The support section may include an air bladder and a control valve fluidly coupled to the air bladder that regulates air pressure within the air bladder. The control valve has a normally closed position and a vent position, wherein the person support apparatus comprises an exercise configuration wherein the control valve is in the vent position and the air bladder is vented to atmosphere.
1. A person support apparatus comprising:
a base frame;
a primary support frame supported on the base frame;
a foot section;
a carriage freely translatable at least between a head end of the primary support frame and a foot end of the primary support frame, wherein the carriage comprises a seat portion comprising a thigh segment;
a selectable trunnion that selectively and severally couples the foot section to the primary support frame and the thigh segment of the seat portion, wherein:
when the trunnion is in a first position, the foot section is pivotably coupled to the primary support frame; and
when the trunnion is in a second position, the foot section is translatable with and pivotably coupled to the thigh segment of the seat portion; and
a support surface supported on the carriage such that the support surface translates with the carriage, the support surface comprising at least one support section which is collapsible in a length direction of the support surface, wherein the at least one support section comprises:
an air bladder; and
a control valve fluidly coupled to the air bladder that regulates air pressure within the air bladder, the control valve comprising a normally closed position and a vent position, wherein the person support apparatus comprises an exercise configuration wherein the control valve is in the vent position and the air bladder is vented to atmosphere.
2. The person support apparatus of claim 1 , wherein:
the carriage further comprises a torso portion; and
the torso portion is inclined with respect to the seat portion when the person support apparatus is in the exercise configuration.
3. The person support apparatus of claim 1 , wherein:
the seat portion further comprises a gluteal segment; and
the thigh segment is pivoted towards the gluteal segment when the person support apparatus is in the exercise configuration.
4. The person support apparatus of claim 1 , wherein the foot section has an extended position and at least one retracted position and the foot section is in the at least one retracted position when the person support apparatus is in the exercise configuration.
5. The person support apparatus of claim 1 , wherein the primary support frame is tiltable with respect to the base frame.
6. The person support apparatus of claim 1 , further comprising a deck at least partially supported on the carriage, wherein the support surface is positioned on the deck.
7. The person support apparatus of claim 6 , wherein the deck comprises a seat portion and a torso portion, wherein the torso portion is pivotable with respect to the seat portion from a recumbent position to at least one inclined position.
8. The person support apparatus of claim 1 , wherein the seat portion further comprises a gluteal segment, wherein at least the thigh segment is pivotable with respect to the gluteal segment.
9. The person support apparatus of claim 8 , wherein the thigh segment is pivoted towards the gluteal segment when the person support apparatus is in the exercise configuration.
10. The person support apparatus of claim 1 , wherein the selectable trunnion comprises two stub shafts positioned at opposite ends of a linear-acting actuator.
