Relaxation device with breathing motion simulator

1 . 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.

2 . The breathing motion simulator according to claim 1 , wherein the cover guidance further comprises a third living hinge unit, wherein the third living hinge unit is oriented in parallel with the first living hinge unit.

3 . The breathing motion simulator according to claim 1 , wherein the second living hinge unit is oriented perpendicular to the first living hinge unit.

4 . The breathing motion simulator according to claim 1 , wherein the living hinge units are positioned along a circumference of the cover plate, and wherein the actuator is positioned in between the living hinge units.

5 . The breathing motion simulator according to claim 1 , wherein the cover guidance and the cover plate are integrally formed as a one piece item.

6 . The breathing motion simulator according to claim 1 , wherein the cover plate has an outer shape which is shaped in correspondence with a human hand palm.

7 . The breathing motion simulator according to claim 1 , wherein the cover plate comprises a push body to be engaged by the actuator, wherein the push body forms a protrusion extending away from an inner side of the cover plate.

8 . The breathing motion simulator according to claim 7 , wherein the push body is a hollow body formed by a plurality of wall portions having each a wall thickness allowing a manufacturing of the push body by injection molding.

9 . The breathing motion simulator according to claim 7 , wherein the push body is configured to be assembled to the inner side of the cover plate.

10 . The breathing motion simulator according to claim 1 , wherein a stretchable layer encloses the cover plate and provides a pre-tension to the cover plate with respect to the base body.

11 . The breathing motion simulator according to claim 10 , wherein the stretchable layer comprises an open-worked region contributing to a movement of the cover plate with respect to the base body.

12 . The breathing motion simulator according to claim 11 , wherein the open-worked region is formed by an elongated cut-out which is directed substantially perpendicular to the linear motion.

13 . The breathing motion simulator according to claim 10 , wherein the open worked region is laterally positioned with respect to the cover plate.

14 . The breathing motion simulator according to claim 10 , wherein the actuator is an inflatable bladder, such that after an inflation, the bladder deflates due to a pre-tension on the cover plate.

15 . The breathing motion simulator according to claim 1 , wherein the breathing motion simulator is a part of a relaxation device, a sleep induction device, or a relaxation monitoring device.

16 . 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 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 living hinge unit comprising at least one living hinge defining a pivot axis extending in a longitudinal direction substantially in parallel with an imaginary plane formed by the base body to guide the cover plate to and fro the base body.

17 . A relaxation device for influencing a relaxation of a user by providing a breathing motion simulation comprising:

the breathing motion simulator according to claim 1 , and

a base body for connecting the breathing motion simulator,

wherein the base body is formed by a housing in which the actuator drive is housed inside an inner space of the housing and wherein the cover guidance is connectable or connected to an outer surface of the housing.

18 . The relaxation device according to claim 17 , wherein the relaxation device is a relaxation monitoring device comprising at least one sensor for monitoring a relaxation of a user, in which a control unit is configured to adapt a simulation of a breathing motion provided by the breathing motion simulator based on a received sensor signal from the at least one sensor.

19 . The relaxation device according to claim 17 , wherein the cover plate of the breathing motion simulator extends in a length direction of the relaxation device, extending from a head portion to a tail portion, about a distance of at least 30% of a total length of the device.

20 . A method for providing a simulation of a breathing motion, comprising:

utilizing the breathing motion simulator according to claim 1 for providing a simulation of a breathing motion.
