Abstract: A supporting device includes first and second supporting flanges coupled with first and second transmissions, respectively, and a support via which a supporting force is transmittable from the first supporting flange to the second supporting flange. The support includes a lever element which is coupled in an articulated manner with an attachment element on the first supporting flange and thus articulated with the first supporting flange, and a supporting element which is coupled in an articulated manner with the lever element and connected to the second supporting flange and which includes two spaced-apart supporting parts. The lever element is arranged partly between two spaced-apart attachment parts of the attachment element and partly between the supporting parts of the supporting element and is coupled in an articulated manner with the attachment element via the attachment parts and in an articulated manner with the supporting element via the supporting parts.

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 centre 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.
