Relaxation device with breathing motion simulator

A breathing motion simulator for simulating an expanding and retracting movement of a breathing, comprising:

• an actuator system including an inflatable bladder and a pump unit including a pump for supplying a fluid to the inflatable bladder;
• a cover plate positioned across the inflatable bladder for covering the inflatable bladder to induce the motion of the inflatable bladder to the cover plate;
• a cover guidance for linearly guiding the cover plate with respect to a base body, in which the cover plate is connected to an upper portion of the cover guidance, and in which a lower portion of the cover guidance is connectable to the base body, wherein the cover guidance comprises at least a first living hinge unit and a second living hinge unit oriented in a non-parallel direction with respect to each other for constraining a rotational movement of the cover plate, wherein each living hinge unit comprises at least three stacked living hinges defining a set of at least three pivot axes in parallel for enabling a translational movement of the cover plate to allow that the cover guidance enables a linear movement of the cover plate.
