US Patent 8701229 Hospital bed

A method of actuating a manually operable brake on a caster wheel of a patient support apparatus to stop motion of the apparatus includes electrically coupling the control system of the patient support to an actuator at the patient support, generating actuating signals with the control system based on input at the patient support apparatus, transmitting the actuating signals to the actuator to thereby actuate the actuator to output a driving force, and mechanically coupling the driving force of the actuator with the manually operable brake to thereby actuate the manually operable brake and thereby brake the caster wheels.
