A scale disposable on a bed frame for measuring the weight of a person in the bed on a mattress, the scale comprising a relatively thin scale frame assembly having overall length and width dimensions related to the dimensions of the bed frame. A plurality of load cells are carried by the scale frame assembly at selected locations in the assembly, each cell producing a signal representative of the weight applied to the frame assembly in its vicinity. A scale control and display device receives the several load cell signals and produces a scale output signal indicative of the weight of a person supported on the mattress. |
