Supporting module for an adaptive sleep system, and adaptive sleep system

Supporting module (100) for an adaptive sleep system, comprising:

• a first, uppermost supporting element (110);
• at least two drive shafts (140, 140′), the drive shafts being situated in a plane, parallel with respect to the first supporting element (110);
• at least two leaf springs (130, 130′) configured to have an adaptable deformation resistance, each leaf spring having a length defined by the distance measured along the leaf spring between a first and a second end,
• wherein each leaf spring is in contact with a drive shaft (140) via a coupling element (150) at a contact point positioned along the length of the leaf spring (130);
• wherein the first ends of the leaf springs are connected to the first supporting element (110) and extend symmetrically in planes parallel to one another;
• wherein the second ends of the leaf springs are directed towards the drive shafts (140, 140′) and converge at their respective contact points so that said leaf springs at least partially overlap in a plane parallel with respect to the first supporting element (110) such that a line drawn through said plane would intersect a portion of the second ends of the leaf springs;
• wherein the distance between the contact point and the first end can be shifted over at least 10% along the length of the leaf spring (130) around its contact point by rotation of at least one drive shaft (140);
• wherein the distance between the contact point and the first end along the length of the leaf spring (130) determines the deformation resistance of this leaf spring (130),
• wherein the deformation resistance of the leaf springs (130, 130′) determines the resilient capacity of the supporting module (100), and
• wherein the coupling element (150) has been configured to transmit the rotational motion of at least one drive shaft (140) to the leaf spring (130), in order to change the distance between the contact point and the first end along the length of the leaf spring (130), and thereby change the deformation resistance of the leaf spring (130, 130′).
