  • Patent number: 7509697
    Abstract: A bed, in particular a sickbed or nursing bed, comprises a height-adjustable bedstead having a frame comprising frame side parts and frame transverse parts and, in the region of the frame transverse parts, legs connected with each other in pairs by means of cross bracings. The legs have lower ends supported on a floor and, at their opposite upper ends, are supported and slidably guided at guiding profiles extending in parallel to the frame side parts. Further, the bed comprises two lifting assemblies each having a drive unit comprising a housing, and a pushrod adapted to be moved out of the housing and into the housing by the drive unit. The two lifting assemblies are arranged in the region of the frame side parts, leaving a space for accommodation of an adjustment drive for an adjustable mattress supporting device.

  • Patent number: 6795988
    Abstract: A bed having supporting elements for supporting the bed on a floor and a mattress support device for supporting a mattress. The mattress support device is provided with a support member that has two transverse bars extending transversely. A safety side part is supported at the support member so as to be moved between a rest position in which it is located below the lying surface and an upright position in which the safety side part extends at a side of a lying surface. An upper surface of the support member defines a mattress support plane and upper faces of the transverse bars are substantially juxtaposed to the mattress support plane.
