Abstract: This invented multiple-phase dynamic cushion comprises a frame, at least a driving source, at least a transmission assembly, and clusters of plural strips interleaved in parallel. Taking a two-phase embodiment as an example, the two-phase strips interleave with each other, in parallel, to form the cushion's surface and alternate their tensions in turn; when one phase's strips periodically tighten to support the user's body, the other phase's strips will loosen, allowing the user's body covered by the loosened strips to take a rest, averting a pressure-ulcer risk. The driving source is energized by an altering energy, making the two strip groups alternate in loosening and tightening states periodically in turn. This invention can be converted into a portable dynamic chair when the four holes on the bottom of its four corners are inserted with legs; it can also be converted into a dynamic support for a lying human body.

Abstract: Stimulation actuators that exert any desired movements on the underspringing arrangement. The underspringing arrangement has lifting members (11) that are mounted elastically by means of elastic elements (14). The elastic elements (14) are arranged such that at least a main direction of work extends at an angle with respect to the direction of the movement of the lifting member. In this way, the lifting member (11) can have a particularly low overall height. The supporting surface of the underspringing arrangement can be moved up and down by the lifting member (11) and the elastic element (14), thereby permitting an individual stimulation and movement of a person lying on the mattress.

The at least one lifting unit (20) comprises a housing (24) with an electromotor (32) having a drive shaft (34), a transmission (38) and a lifting member (50) supported at the bearing element (62) of said one support element (22). The lifting member (50) is adapted to be rotated by the transmission (38) and to be moved both up and down during a rotary movement of 360°.

Abstract: A support base for a bed mattress (3) including a housing (1) having a plurality of transverse slats (2) for supporting said mattress wherein one or more of said slats are individually adjustable relative to said base to provide calibrated positive or negative height adjustment for each slat, characterized in that said height adjustment is provided by a means which is operable external to said housing.

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 bed for patients that require periodic movement of their body parts. The bed includes a rectangular frame with panel members transversally disposed. Each panel member is supported by a pair of eccentric members that in turn are rigidly mounted to two spaced apart shaft that are parallel to each other. The shafts are imparted a rotational force by a motor assembly that generates a reciprocating movement that is translated to a rotational movement applied to the shafts. The eccentric members cammingly engage the underside of the panels, and they are divided in two sets of eccentric members that are aligned with respect to each other so that each set is composed on non-adjacent alternate panels that are lifted when the panels of the other set are brought down.

Abstract: A patient bed including castors (1) resting against the floor, legs or a base frame, and a bed framework (2) and a mattress (3), the mattress further including a number of elongated mattress elements (3', 3", etc.), aligned parallel in the longitudinal direction of the bed, and the bed framework being made of a framing of the patient bed to which framing are attached tubes (8) or similar slats, aligned parallel with the mattress elements of the bed and forming an essentially horizontal plane in which each tubular slat is aligned in the crosswise or longitudinal direction of the bed to essentially coincide with a furrow adapted between the mattress elements. The invention is implemented so that the patient bed is provided with means (5-7) for moving the mattress (3) essentially in the vertical direction between a first plane defined by the tubular slats and a second plane below the first plane and for stopping the mattress at a desired elevation between the two planes.
