Improvements made to therapeutic beds and chairs. The improvements are applicable in therapeutic bed and chair structures, in such a way that on the basis of a mechanism consisting of camshafts 8 connected with each other by gears of the "universal joint" type, 9, they make it possible for groups of elements, 7 and 7', to be alternately raised and/or lowered, in such a way that each of these groups will provide support for the patient's body, with the special feature that the lowering of each group of elements, 7 or 7', does not occur until the other group has risen to its position for use. <IMAGE>
