Systems for patient support surface orientation and displacement
First Claim
1. A backrest pivoting system for a bed, the bed having a frame and a backrest pivotably connected to the frame, the backrest pivoting system comprising:
- an actuator having a first actuator portion connected to an actuator pivot pin movably mounted to the frame and a second actuator portion connected to the backrest for pivoting the backrest relative to the frame, the actuator further having a transmission adapted for operatively coupling the second actuator portion to the first actuator portion;
a release operatively connected to the transmission, the release being movable between a locked position in which the first actuator portion is coupled to the second actuator portion and an unlocked position in which the second actuator portion is decoupled from the first actuator portion to allow free pivoting of the backrest towards the frame;
a resilient member between the frame and the actuator pivot pin, the resilient member being compressible and configured such that the actuator pivot pin moves towards the frame when the release is moved from the unlocked position into the locked position as the backrest pivots towards the frame.

Abstract
There is provided a backrest pivoting system having a backrest and an actuator for pivoting the backrest. The actuator is pivotably connected to the backrest by a pivot defining a first pivot axis. The backrest is configured to pivot about a guide member which defines a second pivot axis coaxial with the first pivot axis. There is also provided a backrest pivoting system including an actuator and a resilient member mounted in series with the actuator. There is also provided an extendable user support assembly comprising a lower body support panel and a core support panel supported by a frame, the lower body support panel being translatable relative to the frame such that an opening is created between the lower body support panel and the core support panel when the lower body support panel is translated away from the core support panel. There is also provided a method for placing a bed in a vascular position.
