ABSTRACT:
The invention relates to profiling beds where sections of the bed can be raised or lowered for the benefit and comfort of the user of the bed. The object of the invention is to prevent a compression of the lower stomach of the user as sections of the bed are raised, an objective met by a construction comprising at least a head and upper body support hingedly connected to a frame, a seat support hingedly connected to the head and upper body support at one end and to the frame at the other, the hinged connections being such that as the head and upper body support is raised about its hinged connection to the base, the seat portion is lowered about its hinged connection to the frame, and the distance between said hinged connections in the longitudinal direction of the bed increasing as the said sections are simultaneously raised and lowered. The object of the invention is further met by a construction comprising at least a head and upper body support hingedly connected to a frame, a seat support and a thigh and lower leg support, the seat support being hingedly connected to the adjacent end of the thigh support and hingedly connected to the frame, the hinged connections being such that as thigh support is raised about its hinged connection to the frame, the end of the seat support hingedly connected to the thigh support is lowered, the distance between those hinged connections in the longitudinal direction of the bed increasing as the said thigh support and seat support are respectively simultaneously raised and lowered.
