1. A weighing bed, comprising:
- means for receiving a patient;
an upper bed frame, having a foot end and a head end, for supporting the patient receiving means;
a lower bed frame;
at least one load cell connected to the lower bed frame;
a rigid load cell bracket, having a foot end and a head end, connected to the load cell such that the weight of the patient is transferred to the load cell through the bracket, the bracket extending along the length of the load cell;
first linking means linking the foot end of the bracket to the upper bed frame; and
second linking means linking the head end of the bracket to the upper bed frame, such that the upper bed frame is movable relative to the lower bed frame for substantial height adjustment of the bed and such that the load cell is responsive to the weight of the patient.

Abstract
A weighing bed (10) which includes a patient support assembly (12), an upper bed frame (14) and a lower bed frame (16). Linkage assemblies and actuators, powered by motors, provide movement capability for the bed (10). Mounted on both sides of the lower frame (16) are load cells (52, 53), each of which has connected thereto a U-shaped rigid bracket (72). First link member (84) connects one end (76) of bracket (72) to a foot portion of the upper bed frame (14), while second and third link members (90, 92) connect the other end (75) of the bracket (72) to a head end of the upper bed frame (14).
