Hospital bed seat section articulation for chair egress
First Claim
1. A hospital bed comprisinga base,an upper frame supported above the base,a deck supported on the upper frame, the deck having a head section, a seat section, a thigh section, and a foot section, the deck being movable between a horizontal position to support a patient in a supine position and a chair egress position to support the patient in a sitting position, anda seat section actuator coupled to the seat section and operable to articulate the seat section relative to the upper frame about an axis located adjacent a foot end of the seat section such that a head end of the seat section lifts upwardly relative to the upper frame to facilitate egress of the patient from the deck when the deck is in the chair egress positions wherein the head section is coupled to the upper frame for pivoting movement about a head section axis that remains stationary relative to the upper frame as the head end of the seat section lifts upwardly relative to the upper frame.

Abstract
A hospital bed includes a base, an upper frame supported above the base, and a deck supported on the upper frame. The deck has head, seat, thigh, and foot sections. The deck is movable between a horizontal position to support a patient in a supine position and a chair egress position to support the patient in a sitting position. The hospital bed further has a seat section actuator to articulate the seat section relative to the upper frame about an axis located adjacent a foot end of the seat section such that a head end of the seat section lifts upwardly relative to the upper frame to facilitate egress of the patient from the deck when the deck is in the chair egress position.
