Definitions

• a rotary bed which is adapted to bring a patient lying in bed in a sitting position on the Bekante.
• the known bed on a height-adjustable pedestal, which carries a rotary hinge on his head.
• About the rotary hinge of the lying or mattress frame is connected to the base and can be rotated from the normal bed position in which the longitudinal axis of the mattress frame coincides with the longitudinal axis of the bed in a transverse position.
• the lying frame is composed of several sections, so that it can be folded in the transversely rotated position to the chair or chair shape Z-shaped.
• the reclining frame forms a backrest, a seat and a down-hanging portion which in support of the bed position Lower leg serves.
• the seat itself is in turn in two parts and comprises a pivotally connected to the central part ' central part and hinged thereto thigh part, which is inserted between the central part and the lower leg part.

• funds are available seen to lift the thigh part in the chair or chair position near the popliteal fossa to some extent.
• the central part together with the thigh part forms a shallow depression.
• This trough position is also maintained even when mattress material is used, which is not suitable per se, a corresponding trough. And thus to create a corresponding seating feeling.
• the resulting shallow recessed seat bounded behind the patient by the back allows the distance between the kink where the back part merges with the seat to be shortened to the kink where the seat edge deflects downwards, without causing the patient to feel unsafe.
• the shortened seating area greatly facilitates the transfer of the patient from the bed to a wheelchair without additional mechanical aids.
• a very simple and reliable way to pivot the thigh part in the sitting position is to use a cam mechanism.
• This cam mechanism can be connected in the simplest case with the lever assembly, which serves to pivot the lower leg part and lift.
• a very simple solution is to use an intermediate frame in which a shaft is rotatably mounted.
• the shaft carries on the one hand lever for giving the lower leg part and on the other hand cams for lifting the thigh part.
• the stability of the assembly is improved when the thigh member has a cross member which is located at the level of the cam, and at the same time serves as a counter surface for the cams. This allows a very even elevation of the thigh part. In particular, this avoids twisting when the patient sits asymmetrically on the thigh part of the mattress frame.
