Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of relaxation, and more particularly to electromechanical relaxation systems.

STATE OF THE ART

Nowadays the sources of stress have become countless and there is an urgent need for quick and effective relaxation solutions.

Pseudo-relaxation solutions are plethora and offer, for example, users sessions in virtual reality to get out of the world around them. These sessions then include a visit to a place considered calm, for example a landscape commonly accepted as "soothing". The user must then wear a virtual reality headset accompanied by a hearing headset and is generally lying or sitting. These solutions generally overstimulate the user's senses so as to impose on him an environment supposed to be soothing. In contrast, there are known solutions known as sensory deprivation. These solutions then use what is called a sensory deprivation box. This type of box is partly filled with water at a temperature of about 37 ° C and saturated with salt so that the user can float. The housing is also soundproofed and perfectly opaque so that the user can float in a noise-free and light-free environment. The temperature being at a temperature close to that of his body, the user does not feel the contact of water. The non-stimulation of the senses of touch, hearing and sight then leads to a loss of the notion of time and a deep relaxation of the user provided that he is experienced. Indeed, several sessions are generally necessary so that the user can get used to the deprivation of his senses. In addition, and this is the most annoying, this type of solution requires the user to be in contact with a liquid implying the wearing of a suitable outfit and the need for cleaning after each session, or even also before. Hygiene issues arise when the box is likely to be used by multiple users. And these sessions assume a relatively long time of experience and present a big problem of physical accessibility.

Finally, document US Pat. No. 5,266,070 is known, which relates to a relaxation seat comprising a plurality of auditory, visual and olfactory stimuli whose function is to immerse the user in a state of relaxation. However, this type of solution requires significant time for the user to reach a deep, lasting and effective state of relaxation for the greatest number.

Today people have had a hard time taking time for themselves, to relax. They therefore aspire to have a quick solution, easy to access and use, and effective to relax and preferably without having to take off their clothes, or to waste an hour trying to relax on a machine not suitable for them.

The present invention aims to at least partially solve the problems set out above.

SUMMARY OF THE INVENTION

The present invention relates to a relaxation system, able to configure the psycho-physiological state of a user, comprising at least one chair intended to accommodate at least one user, said system comprising: o an optical stimulation device; o a hearing stimulation device; o an olfactory stimulation device; said system being characterized in that it further comprises: o a respiratory support device configured to adjust the respiratory rate of said user to a predefined respiratory rate; and in that said system is configured to operate at least one relaxation cycle successively comprising: o at least one pre-relaxation phase comprising at least: a respiratory adjustment of the user's respiratory rate by said respiratory support device to said respiratory rate predefined; an emission of a plurality of stimuli comprising at least stimuli: • optics generated by said optical stimulation device; • hearing aids generated by said hearing stimulation device; • preferably, olfactory generated by said olfactory stimulation device; o at least one relaxation phase comprising at least the emission of a plurality of stimuli during which the respiratory support device is inoperative and comprising at least stimuli: optics generated by said optical stimulation device; hearing aids generated by said hearing stimulation device; olfactory agents generated by said olfactory stimulation device;

Unlike the prior art, the present invention allows the user to remain dressed, and in particular to keep his clothes during the relaxation session.

He will be able to create his own dream or interior journey which will become in his memory an anchor of his better being.

The present invention is configured to avoid the user being equipped with portable accessories (sensory stimulation or sensing) such as headphones, glasses or headphones, or any other system fixed or placed on the body of the user, to allow a maximum feeling of freedom, immersion and escape.

In addition, the present invention is configured not to overstimulate the senses of the user, but on the contrary to simply guide him in an open and free sensory universe where his mind can then release itself from the constraints of stress and finally calm down.

By the clever choice and a significant synchronicity of multisensory stimuli, the present invention makes it possible to create a multisensory bubble in which the user is rocked and guided towards a state of relaxation.

This synchronicity also allows the realization of different programs, to dispose the user in other states such as creativity, lucidity or performance.

Relative to the prior art, the formation of this multi-sensory bubble is progressive which then allows the user to be more quickly and more effectively relaxed. The entire device is also designed to make it accessible to as many people as possible in terms of physical accessibility and for users with less sensory sensitivity.

In particular, the present invention makes it possible to reduce the time of a relaxation session by adjusting the respiratory rate of the user to a predefined respiratory rate conducive to a state of relaxation. This respiratory adjustment is made during a pre-relaxation phase.

In particular, the respiratory support device provides support for the user towards a state allowing him to relax more quickly.

Cleverly, auditory and visual stimuli can be used at the same time as adjusting the user's breathing rate to further reduce the time required for the user to be in a psycho-physiological state receptive to the phase relaxation to follow.

The present invention thus makes it possible, via a pre-relaxation phase, to prepare the user on at least the respiratory aspect for the relaxation phase. The prior art offers relaxation solutions free from the preparatory phase, allowing the user to be in a condition that is both physiological, physical and also psychological, mental. This conditioning is essential so that the user is as receptive as possible to sensory stimulation during the relaxation session. This relaxation session can be a sequence in a plurality of other multisensory stimulation sequences. In a particularly advantageous manner, this conditioning makes it possible to significantly reduce the time of the relaxation session.

The present invention advantageously takes advantage of the synergy between various stimuli so that the user is the least physically stressed and that it is his mind that can flourish in a relaxing environment. This environment is relaxing, because it induces a creation by the imagination of the user where the stimuli are then only activators of construction of a more personal environment that the user creates more freely.

Thus, the pre-relaxation phase is designed to prepare the user for the relaxation phase so that it can be more effective and last less than what the prior art offers.

According to one embodiment, the relaxation system according to the present invention comprises multisensory emission devices, at least one device on either side of the head of the user to ensure a binaural effect and equipped at least with a sound and odor diffuser and which can be supplemented by acoustic vibration, heat and cold and wind diffusers.

The relaxation system may include additional stimulation devices that are mobile and / or arranged in the space surrounding the user, which make it possible to reinforce the immersion effect and the possibilities of spatialization of the stimulation to increase the impact on perception. physiological and mental of the user, which allows to reduce the time of the experience for an even deeper and lasting effect.

The relaxation system may in particular include tactile stimulation devices preferably integrated in the armrests at hand level and consisting of feelers, different shapes and textures, as well as physiological sensors (resistance, sweating, etc.). This system will use the natural support areas of the body on the chair, without constraining the user.

The present invention also relates to a relaxation method comprising a relaxation system according to the present invention and comprising the implementation of at least one relaxation cycle comprising at least the following successive steps: o Installation of the user in the chair preferably in the normal seated position, accessible to all o Preferably, movement, and in particular translation, of the chair towards a multisensory stimulation zone allowing a first psychological immersion effect; o Inclination of the chair in a so-called zero gravity position allowing the user to condition himself for the relaxation cycle; o Start of a pre-relaxation phase comprising at least: a respiratory adjustment of the user's respiratory rhythm by the respiratory support device to said predefined respiratory rhythm; an emission of a plurality of stimuli comprising at least stimuli: • optics generated by the optical stimulation device; • hearing aids generated by the hearing stimulation device; • preferably, olfactory generated by said olfactory stimulation device o End of the pre-relaxation phase; o Then starting at least one relaxation phase comprising at least the emission of a plurality of stimuli during which the respiratory support device is inoperative and comprising at least stimuli: optical generated by said optical stimulation device; hearing aids generated by said hearing stimulation device; olfactory agents generated by said olfactory stimulation device; preferably, epidermals generated by at least one epidermal stimulation device; o End of the relaxation phase; o Preferably, the progressive straightening of the chair until the seat of the chair is in the sitting position; o Preferably, the movement, and in particular the translation of the chair out of the multisensory stimulation zone to facilitate the physical and mental exit from the experience.

Before starting a detailed review of embodiments of the invention, the following are set out optional characteristics which may possibly be used in combination or alternatively: - According to a preferred embodiment, the pre-relaxation phase presents a first step execution time and the relaxation phase has a second execution time, the first execution time being less than the second execution time. - Preferably, the ratio between the second execution time and the first execution time is greater than 1.5, preferably 2 and advantageously 3. - Advantageously, the predefined respiratory rate has a breathing frequency of cardiac coherence, with periods of inspiration and expiration preferably of 5s, preferably able to evolve according to the desired effect. - According to one embodiment, the pre-relaxation phase is configured to slow the respiratory rate, preferably the heart rate, of the user, and to regulate his blood pressure, and to condition his mind in order to increase his sensory perception before the relaxation phase. - A respiratory rate of 5s or more also promotes olfactory perception. Advantageously, the respiratory support device is placed in said chair so as to apply pressure at at least part of the user, preferably at least at part of the user's chest, advantageously at a rear part of the user's chest.

This helps and supports the user to breathe at a predefined breathing rate.

This allows the user to make no special effort to control their breathing rate, the respiratory support device being configured to support the movement of the user's chest during inspiration and expiration. - According to a preferred embodiment, the pre-relaxation phase comprises at least olfactory stimuli generated by said olfactory stimulation device. Advantageously, the respiratory support device comprises at least one actuator taken from at least: a hydraulic cylinder, an inflatable pocket, and the actuator is configured to apply increasing pressure to the back of the user, preferably from the bottom to the top of the user's back, and decreasing pressure, preferably from the top of the back to the bottom of the user's back. Advantageously, the respiratory support device may comprise a mechanism, preferably synchronized, exerting abdominal compression, by means for example of an inflatable pocket, to more effectively accompany the expiration phase.

This helps and supports the user to breathe at a predefined breathing rate.

This allows the user to make no particular effort to control his respiratory rate, to develop much deeper breathing, the respiratory support device being configured to accompany the movement of abdominal breathing to the rib cage, from the user, during inspiration and expiration.

This allows the use of relatively simple, space-saving and quiet technology so as not to annoy the user. - According to one embodiment, the relaxation system comprises at least one epidermal stimulation device, preferably without contact, configured to stimulate at least part of the user's epidermis without direct contact with the user. The absence of epidermal stimulations, otherwise called tactile, from the user in a direct manner makes it possible to precisely control and even through clothing the intensity of the epidermal stimulations so that the user can feel via his sense of touch these stimulations without coming into direct contact with an external solid element. Advantageously, said epidermal stimulation device comprises at least one vibration generator configured to emit vibrations at a frequency between 20Hz and 80Hz and / or between 100kHz and 150kHz.

This stimulates the user's epidermis via acoustic vibrations that are inaudible to the user. At these frequencies, acoustic waves stimulate parts of the wearer's body even through their clothes. Advantageously, said epidermal stimulation device comprises at least one heat flow generator configured to generate a flow of hot and / or cold thermal convection intended for said user. This stimulates the user with a heat flow or a refreshing flow.

This provides the present invention with additional degrees of freedom and therefore a wider range of combinations of stimuli. Advantageously, said epidermal stimulation device comprises at least one generator of an air flow configured to generate an air flow intended for said user.

This allows you to simulate a breeze or even wind, which can also be hot or cold. - According to one embodiment, the pre-relaxation phase and / or the relaxation phase comprise at least one emission of epidermal stimuli generated by said epidermal stimulation device. - According to one embodiment, said optical stimulation device comprises at least one matrix of light emitting elements, preferably a matrix of light emitting diodes, and said optical stimulation device emits optical stimuli having a sufficient light intensity to be perceived by the user with eyes closed, preferably greater than 70 cd, and said optical stimulation device emits optical stimuli according to the entire visual field of the user.

This immerses the user in a bright environment even when the user has his eyes closed. Here again, the present invention wishes to take advantage of the imagination of the user and not impose on it a supposedly relaxing vision which is not adapted to the user's psyche. - According to one embodiment, said auditory stimulation device comprises at least two auditory stimuli generators arranged on either side of the sagittal plane so as to generate binaural auditory stimuli.

This allows spatialization of auditory stimuli in order to immerse the user in a three-dimensional auditory universe. - According to one embodiment, said olfactory stimulation device is configured to successively emit olfactory stimuli intended for the user at an emission frequency greater than 0.1 Hz, preferably greater than 0.5 Hz and advantageously greater than 1 Hz.

This quickly produces odors for the user to create an olfactory environment. Advantageously, the relaxation system comprises at least one device which inhibits at least part of the olfactory stimulation, preferably this inhibitor device comprises a generator of an air flow from the user to a part external to said system.

This increases the dynamics of olfactory stimuli by allowing their inhibition.

In combination with a high frequency emission of olfactory stimuli, this allows the quantity of olfactory molecules perceived by the user to be controlled. Advantageously, the relaxation system comprises at least one olfactory stimulation sensor configured to measure the aerial concentration of the olfactory stimulations.

This allows better control of the quantity of olfactory molecules perceived by the user.

In combination with high frequency emission and controlled inhibition of olfactory molecules, this allows the creation of a feedback loop allowing precise control of the intensity, time and nature of the olfactory stimuli perceived by the user.

In particular, this allows the generation of olfactory stimuli of constant intensity relative to the perception of the user. - Optionally, during the pre-relaxation phase and / or the relaxation phase, the chair is configured to be tilted backwards so that the user is installed in the so-called zero gravity position, and preferably the chair is configured to be tilted backwards at an angle between 10 ° and 80 °, preferably equal to 30 ° so that the user is installed in the so-called zero gravity position.

This allows the user to be placed in a position conducive to relaxation. In particular, this reduces the nerve impulse in the user's brain relative to the constant perception of their own weight, and reduces the load on their cardiovascular system. - According to one embodiment, the pre-relaxation phase comprises at least one emission of olfactory stimuli generated by the olfactory stimulation device. - According to one embodiment, the chair comprises at least one seat, a back, a headrest, two arm rests and at least one leg rest.

The present invention finds as a preferred field of application the relaxation of a user, that is to say at least the reduction in his respiratory rate, or even the reduction in his heart rate.

Cleverly, the present invention also finds for field of application the modification of the psycho-physiological state of a user.

In particular, the present invention makes it possible to configure the various psycho-physiological parameters of a user in order to have them in a state of relaxation, or of creativity or of lucidity or performance for example.

We will now describe the present invention through FIGS. 1 to 4 serving as a nonlimiting example of embodiments of the present invention.

FIG. 1 represents a profile view of a relaxation system 1 according to an embodiment of the present invention. This relaxation system 1 can advantageously comprise a shell 20 intended to at least partially envelop the user 10 during a cycle of use of the relaxation system 1.

This use cycle, also called a relaxation cycle, advantageously comprises at least one pre-relaxation phase and at least one relaxation phase. Such a cycle will be described more precisely below.

This relaxation system 1 comprises at least one stimulation zone 2, that is to say a spatial zone intended to accommodate at least the head 11 of the user 10 and to receive a plurality of sensory stimuli.

This relaxation system 1 advantageously comprises a chair 100 intended to accommodate at least one user 10.

According to one embodiment, the relaxation system can comprise a plurality of armchairs 100 or even an armchair 100 configured to simultaneously accommodate a plurality of users.

This chair 100 advantageously comprises at least one seat 101, a backrest 102, a headrest 103, arm rests 104 and a leg rest 105.

Cleverly, this chair 100 is configured to be arranged in a so-called zero gravity position as described below.

The relaxation system 1 further comprises a plurality of multisensory stimulation devices 200, 300, 400, 500, 600.

In particular, in this figure are shown in a nonlimiting manner: o An optical stimulation device 200; o A hearing stimulation device 300; o A 400 olfactory stimulation device; o A 500 respiratory support device; o A 600 epidermal stimulation device; o A 800 tactile stimulation device;

The respiratory support device 500 is, according to a preferred embodiment, placed in the back of the chair 100. This respiratory support device 500 has the function of helping the user 10 to regulate his respiratory rate in order to reach a predefined respiratory rate, generally slower than that of the user 10 at the start of the relaxation cycle.

In order to allow the user 10 to adjust his respiratory rate to that predefined, the respiratory support device 500 comprises at least one actuator 501.502 intended to apply pressure to a part of the body of the user 10.

This actuator 501, 502 preferably comprises at least one inflatable pocket. Thus, like lungs, the pocket inflates during inspiration and deflates during expiration.

According to one embodiment, this pressure is applied to the back of the user 10. The actuator 501 is then preferably housed in the backrest 102 of the chair 100. Thus, during inspiration, the user 10 feels pressure on his back helping him to reproduce the movement of inspiration.

And when the bag deflates, the pressure applied to the user 10 decreases, which prompts the user 10 to breathe out.

Cleverly, the actuator 501 is configured so that the pressure at the level of the back of the user 10 is variable depending on its area of application.

Thus, during inspiration, the user 10 feels a pressure moving from a part of his back to the top of his back, and during exhalation, the user 10 feels a decrease in pressure from the top from his back to the bottom of his back.

According to another embodiment compatible with the previous one and operating on the same principle, this pressure is applied to the level of the abdomen of the user 10 so as to exert an abdominal compression to more effectively accompany the expiration of the user 10.

According to an advantageous embodiment, the respiratory support device 500 comprises an actuator 501 disposed at the back of the user's back 10 and an actuator 502 disposed at the user's abdomen 10. These two actuators 501 and 502 can then advantageously be synchronized in order to increase the efficiency of the respiratory support device 500.

This respiratory support device 500 thus allows respiratory support for the user in order to physically regulate their breathing according to a gentle and non-invasive method.

According to one embodiment, the relaxation system 1 can comprise a device for measuring physiological parameters 700. This device will be described more precisely below, however according to one embodiment, this device for measuring physiological parameters 700 can include a sensor for measuring the respiratory rhythm of the user 10 so as to calibrate the adjustment of the respiratory rhythm of the user 10 by arranging the rhythm applied to the user 10 by the respiratory support device 500 between that of the user 10 and the predefined one.

Thus, as the user 10 gets closer to the rhythm which is applied to him by the respiratory support device 500, the latter gets closer to the predefined one. This allows the user 10 to gradually and easily change his breathing rate in order to reach the predefined breathing rate.

This respiratory support device 500 allows the present invention to provide faster and more effective relaxation sessions to the user 10 relative to the prior art. In fact, by simply controlling their breathing, user 10 predisposes their body and mind, also called their psyche, to the relaxation phase.

Preferably, the olfactory stimulation device 400 comprises at least one source of olfactory stimulation 401,402, at least one olfactory stimulation inhibitor 405 and advantageously at least one olfactory stimulation sensor 403. These three elements then work in synergy in order to regulate the stimuli Olfactory and more precisely to precisely control the olfactory stimuli received by the user 10. The olfactory stimulation device 400 will be described more precisely below.

In this figure, the relaxation system 1 is arranged in a so-called rest configuration. According to this configuration, the chair 100 has an inclination relative to the horizon close to zero degrees. That is to say that the seat 101 of the chair 100 is substantially parallel to the horizon.

The relaxation system 1 is advantageously provided with a translation device 107 of the chair 100 so as to bring the user 10 closer to the multisensory stimulation zone 2, preferably so as to have at least the user's head in the multisensory stimulation zone 2.

Similarly, the relaxation system 1 comprises a device 108 for tilting the chair 100 backwards so as to place the user 10 in a so-called zero gravity position.

In other words, once the user 10 is installed in the chair 100, it is translated towards the interior of the relaxation system 1, so that at least the user's head 11 is located in the area multisensory stimulation 2, then the chair 100, and therefore the user 10, is tilted backwards at an angle greater than 10 ° and less than 80 ° relative to the horizontal.

Advantageously, the tactile stimulation device 800 can comprise a first 801 and a second 802, sources of tactile stimulation, illustrated for example in FIG. 4. These sources of tactile stimulation 801 and 802 are preferably integrated in the arm rests 104 at the level from the hands of the user 10. These sources of tactile stimulation 801 and 802 can include feelers, differentiated shapes and textures, as well as physiological sensors (resistance, sweating, etc.).

Advantageously, the tactile stimulation device 800 is configured to use the natural areas of support of the body of the user 10 on the chair 100, without constraining the user 10.

FIG. 2 represents the relaxation system 1 according to an embodiment of the present invention in its so-called active configuration.

In this configuration, the user 10 is disposed in the so-called zero gravity position. In this position, the head 11 of the user 10 is disposed between at least a first 301 and a second 302 sources of auditory stimulation.

According to one embodiment, the shell 20 partially carries at least the optical stimulation device 200.

Advantageously, the shell 20 of the relaxation system 1 can be motorized so that the optical stimulation device 200 is placed in the field of vision 202 of the user 10 once the relaxation system 1 is in its active position.

According to an advantageous embodiment, the shell 20 has openings so that the user 10 can both feel a certain intimacy but also an open space.

Preferably, the optical stimulation device 200 comprises at least a first 201, a second 202 and a third 203 sources of optical stimulation comprising, preferably each, a plurality of light emitting elements such as light emitting diodes for example. Advantageously, these light emitters form a matrix of light emitting elements.

According to a preferred embodiment, each light emitting element can emit radiation visible to the user 10 according to a spectrum ranging from 380nm to around 700nm. This allows each light emitter to cover the entire spectrum visible to the user 10 in order to recreate, if necessary, a very wide range of colors and visual effects.

Advantageously, the optical stimuli are configured to remain non-invasive relative to the user 10, and in particular to generate a light atmosphere conducive to the development of the psyche of the user 10.

FIG. 3 represents, according to an embodiment of the present invention, a relaxation system 1 and a plurality of multisensory stimuli.

In particular in this figure, in addition to optical, olfactory and auditory stimulation, the epidermal stimulation device 600 cleverly comprises a vibration generator 601, preferably acoustic vibrations. This vibration generator 601 is configured to emit vibrations that are not audible to the user 10 and at frequencies such that the user's touch 10 is stimulated.

In particular, the use of low frequencies or conversely very high frequencies, makes it possible to stimulate the epidermis of the user 10, see certain internal elements of his organism.

Advantageously, the epidermal stimulation device 600 makes it possible to stimulate at least the epidermis of the user 10 even through his clothes.

This technique of epidermal stimulation by generation of acoustic vibrations at frequencies not audible by the user 10 allows stimulation without direct contact with the user 10 of his sense of touch.

In addition, the epidermal stimulation device 600 can comprise a heat flow generator 602. This heat flow is then felt by the user 10 at the level of his epidermis. This heat flux can be of radiative or convective origin.

Preferably, this heat flow comprises infrared radiation intended to heat the user’s epidermis at least locally 10. This therefore makes it possible for the user 10 to feel heat, for example on his face.

This heat flow may also include a flow of hot air. Conversely or alternatively, or even successively, the heat flow can be a cold flow intended to cause a feeling of cold in at least part of the epidermis of the user 10. This cold heat flow can be generated by Peltier effect for example and / or via the use of an air flow. In this regard, the epidermal stimulation device 600 may include an air flow generator 603 towards the user 10, preferably his head 11.

This air flow generator 603 can then be used to generate a feeling of breeze or wind or even storm for the user 10.

Advantageously, this air flow generator 603 can be used in synergy with the heat flow generator 602 in order to increase or reduce the thermal sensations of the user 10.

In this figure, the presence of the device for measuring physiological parameters 700 is also noted.

This physiological parameter measuring device 700 can advantageously comprise at least one of the following sensors: o User temperature sensor 10, for example by optical measurements; o User 10 heart rate sensor, here again by optical measurements for example; o Sensor of the concentration of oxygen in the blood of the user 10, preferably by optical measurements; o Sensor of the muscular tension of the user 10, for example at the level of his face and by optical measurements; o User 10 respiratory rate sensor, preferably by optical measurements.

Preferably, but not limiting, the device for measuring physiological parameters 700 comprises one or more sensors capable of measuring one or more physiological parameters without direct contact with the user 10, that is to say without physical contact, this so that the user 10 is not hampered by these measures, and advantageously so as not to stimulate a sense of the user 10 by these measures.

According to one embodiment, the measurement of these parameters allows adaptation of the stimuli in order to influence said parameters of the user 10, advantageously to improve the efficiency of the relaxation cycle for example.

FIG. 4 represents a top view of a relaxation system 1 according to an embodiment of the present invention.

In particular, the present invention advantageously takes advantage of an emission of olfactory molecules at high frequencies, considering the kinetics of odor emission. In fact, the present invention can use piezoelectric emitters of scents whose emission frequency can be of the order of a second and whose emission intensity is controlled.

In the prior art, when an odor is produced, the intensity of perception of this follows a bell-shaped curve, that is to say with an intensity increasing to a maximum and then decreasing.

If you want to have a constant intensity, it is advisable to emit a controlled quantity of olfactory molecules at a precise moment, because with each emission there is an accumulation of olfactory molecules which can lead to an increase in intensity.

The present invention, by precise control of the emission, of the quantity of olfactory molecules close to the user 10 and of the inhibition of these molecules makes it possible to generate olfactory stimuli which are relatively constant, even perfectly constant, apart from measurement uncertainties. . The sense of smell of the user 10 can thus be continuously stimulated by the same odor, for example without the presence of a repeated intensity peak, unless this is desired.

This pre-relaxation phase makes it possible to drastically reduce the time of a relaxation cycle by preparing user 10 to be relaxed. In fact, the respiratory support of the user 10 quickly enables him to reach a respiratory rate and preferably a heart rate, conducive to an advanced state of relaxation. This pre-relaxation phase allows the next phase, that is to say the relaxation phase, to be more effective and shorter in time than what the prior art offers.

This pre-relaxation phase thus advantageously comprises respiratory support for the user 10 in order to guide him towards a predefined respiratory rate and preferably conducive to relaxation.

This pre-relaxation phase can also include a plurality of stimuli which are also configured to accompany the user 10 towards a state of calm and peace. o End of the pre-relaxation phase;

This phase of relaxation then includes the creation of a multisensory universe, more precisely the contours of a multisensory space in which the user 10, preferably his psyche, will be able to flourish and “furnish” this space with his leisure. images, thoughts, emotions. Multisensory stimuli then have no other effect than allowing the definition of an environment of psychic freedom for the user 10. o End of the relaxation phase; o In a particularly advantageous manner, the relaxation phase has a second execution time of less than 10 minutes, preferably less than 5 minutes and advantageously less than 3 minutes.

Preferably, the second execution time is greater than the first execution time.

Advantageously, the second execution time represents the major part of the relaxation cycle.

Preferably, the second execution time represents more than 50%, preferably more than 70% and advantageously more than 75% of the execution time of the relaxation cycle. o Inclination 108 of the chair 100 in a position in which the seat 101 of the chair 100 is parallel to the horizon; o Translation 107 of the chair out of the multisensory stimulation zone 2.

A relaxation cycle can also include a final phase during which the respiratory support device 500 is active, with or without the emission of at least one of the stimuli described above.

The stimulus transmissions can be simultaneous or successive, according to predefined stimulation programs.

Advantageously, a computer program comprises all of the instructions executable by a processor in order to allow the implementation of this method.

The present invention tends to create a multisensory universe in which the psyche of the user is free to create the mental representations of his choice, this multisensory universe which is intended only to guide the user to a space of freedom creative and imaginative where the mind of the user can relax.

In other words, the present invention allows the user to deeply relax his mind and body by allowing him to dream while being awake.

The present invention thus allows a simple, rapid and effective relaxation of a user retaining his clothes.

During a relaxation cycle, the user has the sensation of carrying out a waking dream allowing his mind to release the stored stress. The invention is not limited to the embodiments described, but extends to any embodiment in accordance with its spirit.
