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.

Abstract: A hydrodynamic sprung surface bearing having at least two bearing elements bearing against a tube-shaped container which is filled with a substantially incompressible medium, and against which side walls bear. Surfaces of the bearing elements bearing against the container are, in total, smaller by one order of magnitude than a surface of the container wall. Even for scarcely progressive, low pressure forces, the preferably T-shaped or anchor-shaped bearing elements cause overturning in a negative stroke direction, along with a pronounced change in shape of the container, and positive arching and consequently a very large coarse contour adaptation stroke. Therefore, a positively supporting adaptation stroke of the bearing elements is achieved. Overturning results in two separate chambers which bring about an inherent progressive damping by effectively reducing streaming through of the substantially incompressible medium.
