Abstract: A base for bed mattress having a plurality of transverse slats, with each slat end attached to the frame of the base and pivotally connected to first end of a rod at the center of each slat is provided. The rod is attached at its second end to a dynamic pulley. The dynamic pulleys are connected by a common cord or flexible attachment running over stationary pulleys mounted between the slats to a central beam attached to the frame of the base. Improved distribution of human body support can thus be achieved independent of the contour and weight of the body at any sleeping position. Springiness of the base can be modified by changing the elasticity of the flexible attachment. The dynamic support base reduces the need for thickness of the mattress and of the bed pillow.

Abstract: A coupled waveband (14, 21) suspension for bed underframes, seating, upholstery, and mattresses consists of several sinusoidal wavebands (14, 21) which run parallel and/or transversely to the longitudinal axis. Support elements (12, 35) are rigidly or moveably fixed to or ride on the crests or maxima of the wavebands (14, 21). The troughs or minima are supported by slide or roll bearing elements (17) affixed to the frame. A strong interactive coupling is achieved between the support elements (12, 35) causing a positive stroke of the less pressure-loaded segments and the appropriate support elements by the simultaneous lowering of the pressure-loaded waveband segments. The wavebands (14, 21) are manufactured out of higher quality, elastically flexible sold plastic or foam material, or of spring steel band or wire, duralumin, or out of formed laminated wood.

Abstract: An apparatus in the form of a bed or chair for providing relaxation therapy and prevention of decubitis sores is distinguished by the use of flexible beams of the nature of leaf springs. Instead of being lifted up and down by rather complex apparatus only a single shaft carrying cams is provided which acts on the leaf spring-like beams to flex them upwardly and/downwardly to provide the required action. Preferred cams provide no lifting action but only intermitted depressing action of these beams which reduces vertigo and nausea effects and can be slid onto a cam shaft in any one of a multiple alternative angular positions. This enables selection of the travelling wave action for relaxation therapy and of the decubitis preventing action.
