Abstract

A vehicle for use in hospitals, and the like, giving better mobility, steering, braking and passenger handling while providing comfort to the passengers from the time they lay down until they are standing on the side through the rotation and tilting ability of the frame.

Claims

1. A method of translating a hospital bed, comprising:

rotating a patient sleep support surface having back, seat and leg sections to a side egress chair position,

tilting the seat section down with a forwardmost part of the seat section residing below a rearwardmost part of the seat section while the back section is held upright above the seat section to define a stand-assist side egress position thereby facilitating a patient'"'"'s egress from the bed; and

moving a pair of spaced apart side rails, one attached to each opposing side of the leg section, from a horizontal orientation in a hospital bed position to an upright orientation in the side chair and side stand egress positions, so that the side rails reside upright on opposing sides of the leg section and extend outwardly forward a distance beyond the leg section of the patient sleep support surface.

2. The method of claim 1, further comprising extending the side rails down a distance when the bed is in the side egress position so that a lower portion thereof resides proximate a floor and an upper portion thereof resides proximate a lower portion of the seat section.

3. The method of claim 1, wherein the moving step includes positioning an upper portion of the side rails to reside at a height that is above a lowermost portion of the seat section when the bed is in the side egress positions.

4. A method of translating a hospital bed, comprising:

slidably rotating a plate that supports back, seat and leg sections of a patient sleep support surface from a hospital bed position to a side egress chair position with the seat section being substantially horizontal;

tilting the seat section down with a forwardmost part of the seat section residing below a rearwardmost part of the seat section while the back section is held substantially upright to define a stand-assist side egress position thereby facilitating a patient'"'"'s egress from the bed; and

moving a pair of spaced apart side rails, one attached to each opposing side of the leg section, from a horizontal orientation in a hospital bed position to an upright orientation in the side egress positions, so that the side rails reside on opposing sides of the leg section in an upright orientation and extend laterally outward a distance beyond the leg section of the patient sleep support surface.

5. The method of claim 4, wherein the moving step includes positioning an upper portion of the side rails to reside at a height that is above a forward portion of the seat section in the side egress positions.
