Abstract
The hospital bed is provided with a scale assembly which is incorporated into the bed between the bed support frame and patient supporting section. The links which connect the patient support section to the bed support frame are connected to the load frame of the scale assembly so that weighing may occur in any position of the patient support section. The scale assembly is connected to the transverse beams of the bed support frame in a depending manner via bolts. Linear variable differential transformers are used to obtain read-out signals for the displacement of the load frame as a measure of the weight on the load frame.
