Description

Rest device

The invention relates to a device for allowing a user to adopt a sitting position of rest and comfort

More specifically, the invention relates to the field of rest in a means of transport. In particular, the device according to the invention can be used during transport by plane, bus, train, etc. In general, the device according to the invention can be used in all types of transport. However, the device according to the invention is not limited to the field of rest in transport and can also be used in any other field in which a user wishes to rest or relax, for example at home, at the office, etc.

When traveling in transport, a traveler often has to sit in a seat for a long time. This sitting position may, however, be particularly uncomfortable and may not be satisfactory for resting or sleeping.

Devices are already known allowing a traveler to rest or relax more easily during trips in a sitting position. Thus, US 5645319 discloses an inflatable pillow on which a seated passenger can lean forward and rest his head to rest. The shape of the pillow, once inflated, is predetermined to substantially occupy the space in front of the passenger and be wedged on a support means, such as a seat pad for example. However, such a device does not allow the traveler to have an optimal position during long journeys to sleep. In particular, it does not allow to keep the traveler's head in a pleasant position. This can lead to painful muscle contractions, especially in the neck.

Also known is US 2010205743 describing a head and neck support device that also allows a user to rest. The device has a circular shape with an opening in the center that allows the user to insert and rest his head. The support device also has holes at its base that allow airflow to and from the user's face to allow him to breathe.

Also known is US 6721978 describing a device which comprises a head support and a thoracic support support. In particular, the head support support includes an opening for a user to insert and rest his head.

However, these devices do not provide a particular position for holding the arms and hands of the user.

There is therefore the need to improve the position of a user so that it can relax in a sitting position during journeys of medium or long duration.

To remedy the problem mentioned above, the invention relates to a device intended to enable a user to adopt a sitting position of rest, the device comprising at least an upper head holding portion and a lower support portion, the upper head holding portion comprising an upper opening adapted to receive the face of the user, the lower portion of support for maintaining the device in support on a support, the device resting on the support being adapted to support the weight of the head of the user, the device also comprising at least two lateral openings allowing the user to position his arm under the upper portion of the head.

With these provisions, the user has a rest position allowing him both to maintain his head, or his bust and his arms and hands in a pleasant position to relax or sleep.

Hereinafter a detailed discussion of several embodiments of the invention accompanied by examples and reference to the drawings.

Figure 1 shows a device 1 according to one embodiment of the invention.

According to this first embodiment, the device 1 has a generally parallelepipedal shape, in particular cubic. However, the device 1 according to the invention is not limited by such a shape and may be by way of example a spherical shape, cylindrical or other.

The device 1 comprises an upper portion for holding the head 3 (hereinafter referred to as the "upper portion") and a lower support portion 4 (hereinafter referred to as the "lower portion").

The lower portion 4 may also comprise a peripheral portion 5 extending to the upper portion 3. As shown in Figures 1 to 6, the peripheral portion 5 may in particular comprise a front portion 5A, a rear portion 5B.

It is understood that the "front" and "rear" qualifiers applied to device 1 and its components are understood when a person uses device 1 in normal condition to rest, the term "before" qualifying a relatively close element of the user, the term "back" qualifying a more distant element.

In normal condition of use of the device 1, the peripheral portion 5, in particular the front portion 5A and the rear portion 5B of the device 1, extend substantially vertically. In normal use also, the lower portion 4 comprises a lower face 4A which extends substantially horizontally.

The qualifiers "vertical" and "horizontal" applied to the device and its constituents are understood according to their usual meaning and include in particular when the lower face 4A of the lower portion 4 of the device 1 is disposed in a normal condition of use on a support itself horizontal such as a completely unfolded shelf 11 of seat 12 as will be described below, or on the knees of the user, if necessary with a cushion or an interposed bag. When the device 1 is used by a user seated behind a front seat 12, the rear portion 5B may bear, at least partially on the rear of the back of the front seat 12.

As shown in Figures 2, 8 and 10, the faces of the front and / or rear portions 5A, 5B of the device 1 may also be slightly curved. The front portion 5A thus allows a thoracic support of a user 8 on the device 1 as will be described below. The front portion 5A may further comprise a recess 6 at its lower portion as shown in Figures 1, 5 and 7. As can be seen in FIGS. 2 and 8, the upper portion 3 is preferably slightly inclined towards the front. The upper portion 3 thus comprises an upper face 3A, for example inclined at an angle α of between 1 and 60 degrees, and more precisely about 40 degrees, with respect to the lower face 4A of the lower portion 4.

FIG. 3 represents a view from above of the device 1 according to one embodiment of the invention. In this FIG. 3, the upper portion 3, and in particular its upper face 3A, comprises an upper opening 7. The upper opening 7 is in particular centered on the upper portion 3, the upper opening 7 is at least defined by one side The upper opening may also be bounded by a backside 7B. Those listed before and / or rear 7A, 7B are preferably inclined surfaces towards the inside of device i adapted to engage with a portion of the user's face 8. More ^"precisely, the front side 7A of the upper opening 7 is adapted so that the user 8 can rest on the device 1 at the level of his face below the mouth The rear side 7B of the upper opening 7 is adapted so that the user 8 can come rely on the device 1 at the level of his f have.

Figure 11 shows a top view of the device 1 according to another embodiment of the invention. According to this embodiment, the upper opening 7 has a trapezoidal shape. The front side 7A and the side 7B are arranged parallel to each other. The front side 7A has a shorter length than the rear side 7B. The opening 7 has an axis of symmetry. Furthermore, the upper opening 7 may also include lateral sides 7C, 7D, in particular inclined inward, extending respectively between the front side 7A and the rear side 7B. The lateral sides 7C, 7D of the upper opening 7 are adapted to support the cheeks and temples of the face of the user 8.

In this way, the upper aperture 7 is. delimited by the side ava t. 7A., The outer side 7B and. by the lateral sides 7C. The upper opening 7 thus comfortably holds the user's head 8 at the chin, forehead and along opposite sides of the face. The front side 7A, the rear side 7B and / or the lateral sides 7C may also comprise flaps 23. Flaps 23 consist of material extensions, advantageously nonvolatile, extending partially at the level of the upper opening 7. The flaps 23 are for example in the same material as the device 1, in particular made in one piece with the material of the device 1.

The flaps 23 are adapted to prevent the user from being irritated or even cut off, the face when he places it in contact with the sides 7A, 7B, 7C, 7D of the upper opening 7. They also allow, to avoid marks on the face during prolonged use.

The upper opening 7 is sized to receive the face of the user 8, including the mouth, nose and eyes, so that the user 8 can rest his head face down on the device 1. In particular, the mouth, the nose and the eyes of the user 8 are. located in the interior of the upper opening 7 and are not in direct contact with the device 1. The head of the user 8 is then positioned in a straight manner, that is to say without the user S needing to turn the head to the side. This position, even preserved for a long time, is particularly pleasant because it avoids the appearance of possible painful muscle contractions in the neck.

Moreover, the lower portion 4, and in particular the peripheral portion 5, is perforated. As illustrated in the figures, the peripheral portion 5 thus comprises at least two lateral openings 9. In particular, these lateral openings 9 may in particular be between the front portion 5A and the rear portion 5B of the device 1. Moreover, these lateral openings 9 may each be of substantially rectangular shape or have another shape such as circular or other.

As illustrated in the embodiment shown in FIG. 13, the lateral openings 9 advantageously have a rectangular shape, rounded at its edges. Each lateral opening 9 is thus delimited by at least one lower side 9A and one upper side 9B. The lower side 9A and the upper side 9B are parallel to each other. Two lateral sides 9C, 9D extend respectively between the lower side 9A and the upper side 9B. The lower side 9A, the rear side 9B and / or the lateral sides 9C, 9D may also comprise flaps 23, such as those described above concerning the sides 7A, 7B, 7C, 7D of the upper opening 7. Advantageously, only the lower side 9A comprises a flap as shown in Figure 13. The flap 23 of the lower side 9A can prevent irritation of the arms of the user when they positioned in the side openings 9 of the device 1. The flaps 23 therefore participate in a better comfort when using the device 1.

The lower portion 4 further comprises an inner face 10 located inside the device 1. By "inside", it should be understood that the inner face 10 is located in an internal space 2 of the device 1 more particularly delimited by the upper portion 3 and the lower portion 4. The inner face 10 may thus be delimited by the peripheral portion 5 and in particular by the front portion 5A and the rear portion 5B of the device 1. The inner face 10 is preferably substantially horizontal and extends parallel to the lower face 4A of the lower portion 4 of the device 1 as shown for example in Figures 7 and 8. Alternatively, as shown in Figures 1 and 2, the inner face 10 may also be slightly curved. The lower face 4A is advantageously a solid face, that is to say devoid of aperture or hole, as illustrated in FIG. 12.

The inner face 10 also extends between the two lateral openings 9 of the device 1. Thus, the device 1 is traversed on either side laterally between the two lateral openings 9. The upper opening 7 also opens into the space internal 2, and in particular on the inner face 10 inside the device 1.

The lateral openings 9 and the inner face 10 allow the user 8 to position his arms and his hands during the use of the device 1. More specifically, the user 8 can pass each of his arms through a lateral opening 9 under the upper portion 3. The user can thus place his hands, for example one on the other, on the inner face 10 of the device 1.

By positioning its head in the upper opening 7 and its arms in the side openings 9 of the device 1, the user 8 can thus take a rest position to sleep, rest or relax, especially in transport. FIG. 4a shows more particularly a use in normal condition of the device 1 in which the user 8 has a sitting position of rest, the device 1 being placed on an unfolded shelf 11 of the seat 12 situated in front of the user 8. In this use , the rear portion 5B of the device 1 can be supported on the front seat 12, as shown in Figure 4b.

In particular in the embodiment in which the device 1 is used in a transport means, the device 1 may also comprise a vertical extension 13 located at the rear of the upper portion 3, as shown in FIGS. and 9. The extension 13 thus vertically extends the rear portion 5B upwards. This extension 13 is in particular adapted to prevent the head of the user 8 from directly striking an object placed behind the device 1 in case of impact or collision. In particular, in the embodiment where the device 1 is disposed on a seat pad 11, the extension 13 protects the user 8 and cushion a possible shock between the user 8 and the seat 12 located in front of him . The extension 13 also makes it possible to avoid such an impact when the device 1 is placed on the knees of the user 8, in particular in the safety position as illustrated in FIGS. 9a or 9b and as will be described below, in case of violent braking during an emergency landing.

Alternatively, in the absence of extension, the rear portion of the upper portion of the head retainer 3 can prevent the head of the user 8 does not directly hit an object placed behind the device 1. The front portions and rear 5A, 5B can be full, that is to say do not have openings as shown in Figures I, 10 and 14. The front portion 5A can thus notably serve as a thoracic support for the user 8. However, the front and / or rear portions 5A, 5B may also include an opening 14.

In particular, the front portion 5A of the device 1 may be completely or partially open, the upper opening 7 not being then delimited by a front side 7A but also extending at least partially at the front portion 5A of the device 1. According to this embodiment, the user 8 in the resting sitting position does not rest on the device 1 at his chin but only, at his forehead, on the rear side 7B of the upper opening 7 .

The rear portion 5B may also comprise an aperture 14 of any shape, for example circular or rectangular, as shown in FIG. 5. The opening 14 located on the rear portion 5B of the position 1, in which the two side apertures 9, which are used to evacuate the air and heat released by the user from the inside, and in particular from the internal space 2 of the device 1, to the outside. The lateral openings 9 also allow such an air evacuation. According to an embodiment shown in FIG. 6, each lateral opening 9 can be obscured by a concealing device 15. The occulting devices 15 are thus arranged facing each lateral opening 9 and can be fixed for example to the device 1. Such occulting devices 15 allow the user 8 to isolate himself from the outside when he is in the rest position. The rest position is then more conducive to relaxation or napping and allows for example to be placed in at least partial dark, if not total, to watch a movie or read on an electronic tablet, or play for example. For this purpose, the internal space 2 of the device 1 may include a smartphone support (also called "smart phone" in French) or tablet.

As shown in FIG. 6, the blackout devices 15 are for example curtains, in particular fixed above the lateral openings 9, by self-gripping means or by snaps to be detachable by the user 8 if necessary . Alternatively, the blackout devices 15 may for example be one or more flexible flaps attached to the sides of each side opening 9. The device 1 has a height h adapted to prevent the user 8 is too leaning forward when he is in a rest position. For example, the device 1 may have a vertical height h at the rear portion 5B equal to about 40 centimeters. The device 1 may also have a width L and a length 1 respectively between 20 and 30 centimeters. As shown in FIG. 4a, the device 1 may have a size and a shape more precisely adapted to be disposed on a seat shelf 12 situated in front of the user 8, or even resting on the front seat 12, as shown on FIG. Figure 4b. In addition, to prevent the device 1 can slide on the support, and in particular on the tablet 11, the device 1 may comprise a non-slip edge or a non-slip surface 17 at least partially covering the lower face 4A of the lower portion 4 of the device 1. More generally, the device may have a size, and in particular a height h, adapted according to its user 8. As shown in FIGS. 5 and 6, and in order to be able to be used by persons of large size, the device 1 may also include an additional element 16, in particular inflatable, for raising the device 1. In particular, the additional element 16 is placed under the lower portion 4 of the device 1. The additional element 16 can to be fixed to the device 1 for example by self-gripping strips, snaps, or other. The additional element 16 can in particular be used when the device 1 is placed directly on the knees of the user 8, in particular in the safety position as will be described below. According to this embodiment, the additional element 16 is then placed between the knees of the user 8 and the lower portion 4 of the device 1.

The device 1 is preferably formed of a light material so as to be easily transportable. The weight of Device 1 is preferably less than 300 grams (g), or even less than 250 grams (g). It is for example greater than 100 grams. Moreover, in order to improve the comfort in the rest position, the device 1 can in particular comprise a material adapted to deform slightly, for example with a shape memory, such as a foam or a gel, so as to conform ergonomically to the facial shape and / or hands of the user 8. The device 1 is also covered by a covering cap made of a plastic material, fabric, velvet or other. The covering cap itself may also include a foam or a gel to improve the ergonomics of the device 1. The covering cap may also include the blackout devices 15, including curtains or flexible shutters as described above.

For reasons of hygiene, a disposable single-use coating may also be placed on the device 1 for each use or for each different user 8. This coating may, for example, make it possible to cover at least the upper portion 3 of the device 1, In particular, the front and back sides 7A, 7B, 7C of the upper opening 7. As can be seen in FIG. 15, the covering may for example be a cover 22 that can be removably assembled on the device 1. The cover 22 advantageously covers the upper portion 3 while leaving accessible the upper opening 7. The cover 22 is held on the device 1 by any means, for example by means of an elastic of the cover disposed around the device 1. The device 1 can also be an inflatable device. The device 1 can thus be alternately in two states, a folded state and an inflated state. In the folded state, the device 1 is empty of gas, and has a small internal volume, or even zero. The device 1 can thus be folded to occupy a small space. It can thus be easily transported or stored in a compartment, for example on the side or under the seat 12 of the user 8. In the case of an inflatable device, the weight given above is the weight of the folded device. In the inflated state, the device 1 is unfolded so that the user 8 can use it, in particular by taking the rest position as shown in Figure 4a. In particular, in the inflated state, the device 1 is adapted so that the user 8 can rest on the latter in the rest position, in particular at the level of the upper opening 7 on which the head of the the user 8. Thus, the device 1 resting on a support 11 is adapted to support the weight of the user 8, including its head.

The device 1 can be totally inflatable. By totally inflatable means that the device 1 does not include additional non-inflatable rigid elements adapted to support the weight of the head of the user 8, as can be seen for example in the embodiment of FIG. Alternatively, the device may be partially inflatable. According to this variant, the device 1 may for example comprise a portion of the lower support portion 4 of foam, in particular the portion between the inner face 10 and the lower face 4A, while the rest of the device 1 is inflatable. When the device is fully inflatable, it may include flaps, as described above, these being non-inflatable by being separated from an inner chamber by a weld.

In order to be inflated, the device 1 comprises an inflation valve 18, that is to say an injection gas injection passage. The inflation valve 18 is in particular located on the lower portion 4 of the device 1, in particular on the front portions 5A or 5B rear. The device 1 therefore comprises a single chamber to inflate.

The inflation 8 can be performed manually by the user by blowing directly to the mouth in the inflation valve 18. The device 1 is adapted to be inflated quickly by a user 8. Advantageously, the device 1 is sufficiently inflated after the User 8 has blown between 3 and 8 exhalation of air in the device, in particular less than six air exhalation. The internal volume of the device is thus between 10 and 20 liters, especially between 12 and 15 liters.

Alternatively, the inflation can be achieved by connecting the device 1 to an automatic inflation system such as a foot pump or an electric pump (not shown in the figures). In addition, an inflation tube of variable length can be connected to the inflation valve 18 with an injection inlet in the device 1 opposite. The inflation tube thus makes it possible to inflate the device on an air outlet. located for example near the seat 12 of the user 8. For example, such an air outlet may be an air conditioning outlet of the transport means. The inflation valve 18 may also consist of a drain valve for rapidly deflating the device 1. The inflation valve 18 may for example be closed by a plug.

According to an exemplary embodiment of the invention, the inflation valve 18 may comprise a dual inflation system. A first inflation system can inflate or deflate quickly, see almost instantly, the device 1. Such a first inflation system is particularly useful if the device 1 must be inflated or deflated in an emergency situation for example. A second inflation system allows a more precise inflation, for example directly to the mouth by the user 8, especially if the prior inflation using the first inflation system is not sufficient to fully inflate the device 1 An inflation valve 18 comprising such a dual inflation system is known per se and will not be described in more detail.

According to the embodiment of the invention illustrated in Figure 10, the inflation valve 18 may be a valve comprising a non-return valve. A non-return valve is adapted to pivot in front of the opening of the valve in order to close it or to open it.

The non-return valve makes it possible to inflate, advantageously manually, the device 1, for example by blowing directly into the mouth in the inflation valve 18. However, when the user stops blowing in the valve 18, the non-return valve closes the opening of the valve under the effect of the overpressure of the air contained in the device 1. The device 1 does not deflate. In addition, a valve comprising a non-return valve is also adapted to allow rapid deflation of the device 1. For this purpose, the user presses against the check valve of the valve, so that the opening of the valve is no longer closed and that the air can escape the device 1. This results in ease of use of the device 1, for example when the user has finished using the device 1 and wants to deflate. A valve comprising such a check valve ^¬ return is known per se and will not be described in more detail.

The device 1 can be inflated differently depending on the wishes and preferences of the user. In particular, a user may wish to under-inflate the device 1 so that it is more flexible during use, or is more suited to its size or its sitting position. However, although underinflated, the device 1 remains adapted to support the weight of the face of the user, in particular to be used in a rest position as shown in Figure 4a. The device 1 may also include an internal structure adapted to allow the device to be inflated automatically, for example with the aid of the first inflation system described above. More precisely, the internal structure of the device 1 makes it possible to expand the device 1 by volume as soon as the inflation valve 18 is open. The internal structure may for example be composed of a honeycomb structure, the cells being in fluid communication with each other. The internal structure may also include a structure of the type "Accordion" which by deploying, deploys and inflates the device quickly 1. A non-limiting example of such an internal structure of the device 1 is already known per se and is described for example in US 3378864.

Of course, the invention is not limited to the embodiments described above and provided solely by way of example. It encompasses various modifications, alternative forms and other variants that may be considered by those skilled in the art in the context of the present invention and in particular any combination of the different modes of operation described above, which can be taken separately or in combination. In particular, although the invention has been described for an application in the field of rest, the invention can also find an advantageous application in the field of transport safety. In particular, the device 1 can be used by a user 8 to take a safety sitting position similar to the rest position described above. For example, this may be the case to prevent a shock during an emergency landing on the order of an airplane crew. According to this last embodiment, the device 1 can also be used as an airbag type safety device. An inflation gas-generating cartridge can then make it possible to inject gas very rapidly into the device 1 in order to obtain a very rapid inflation, to see almost immediately. This cartridge is used to inject the required amount of gas. This cartridge can be actuated by a dedicated gripping device, as shown in Figure 9b. The device 1 can then be positioned on the user's lap 8. As shown in Figure 9a, the user 8 then has a similar position to the rest position described above, however, being more bent forward than in the rest position. The user 8 thus adopts a safe position adapted to protect himself during a collision of the means of transport or to cushion an impact. In this case, the device 1 is supported on the front seat, as shown in Figure 9b. In particular, this position protects the head and vital organs.

The integration of an inflation cartridge and a dedicated gripping device in a device that does not offer the safety function is also envisaged. To allow evacuation of the user 8 easy in case of emergency, the device 1 can be quickly deflated by the user 8. According to this embodiment, the device 1 may comprise a pre-tear portion 19 shown in dashed lines in the figure 8 to tear the wall of the device 1 to quickly deflate the device 1. Once the wall torn, the device 1 then becomes unusable and must be replaced.

The device 1 is advantageously made from a pattern 28. The pattern 28 has a shape in cross or T, more particularly shown flat in Figure 16. The pattern 28 can draw two layers 26, 27 superimposed l The two layers 26, 27 are more closely connected to each other at their circumference 29, as well as to one another. around the openings 7 and 9, by a peripheral weld. A single layer 26 is more particularly visible in FIG. The two layers 26, 27 are advantageously impervious to air. The two layers 26, 27 are for example a plastic material, especially polyvinyl chloride (PVC).

The two layers 26, 27 may in particular be different from each other. The two layers 26, 27 may be of different colors so as to form a two-color device 1 once assembled. By way of example, the internal space 2 of the device 1, formed by the layer 27, may have a different color from the outside of the device 1, formed by the other layer 26. In addition, one of the layers 26 27, or both layers 26, 27 of the device 1 may be transparent.

The device 1 is then made by assembling the edges with each other. According to the example of Figures 10 and 16, each layer 1 of the device 1 comprises more particularly 6 faces. The assembly of the device 1 can be made from the pattern 28 by stitching or gluing the edges with each other, or by any other means. This step can in particular be performed in the factory, so as to ensure its reliability. In this case, the device is delivered closed, and no assembly step by the user is necessary. "Closed" in this context does not refer to inner tubes, which are necessarily closed, besides allowing them to be inflated via a valve, but to the device itself, in that all the edges are joined together. For the user, it is not expected that he can pass his device in the configuration of Figure 16. Some portions of the device 1 may further include structural welds. A structural weld locally connects the two layers 26, 27 with each other. Such a structural weld can be achieved by high frequency bonding, or by any other means.

Thus, as can be seen in FIG. 12, the lower portion 4, in particular the lower face 4A, may comprise at least one structural weld 21. The lower portion 4 may in particular comprise two structural welds 21A, 21B. The two structural welds 21A, 21B extend longitudinally, at least partially, between the front face 5A and the rear face 5B of the device 1, without joining two other peripheral welds of the device. The two structural welds 21A, 21B making it possible to obtain a flatter lower face 4A, so as to improve the retention of the device 1 on a support 11. In particular, the lower portion 4 thus comprises three inflatable beads 24A, 24B, 24C, separated from each other by the structural welds 21A, 21B. In addition, the presence of structural welding limits the internal volume of the inflation chamber of the device to inflate, while ensuring a better strength of the device 1. Other portions of the device 1 may also include such structural welds. In particular, as can be seen in FIG. 14, the rear portion 5B may comprise at least one structural weld 20. The structural weld 20 of the rear face extends in a rectilinear manner vertically, at less partially, between the upper portion 3 and the lower portion 4.

The structural weld 20 thus delimits two inflatable beads 25A, 25B of equal size. The inflatable beads 25A, 25B extend substantially vertically, parallel to each other. The inflatable beads 25A, 25B make it possible to ensure better resistance of the device 1 during its use.

In one embodiment, the structural welds 20, 21A and 21B described above are the only three structural welds of the device. Although the device 1 has been described above in connection with a precise sitting position of the user 8 as shown in Figure 4a, in particular in which the face of the user 8 is received in the opening upper 7, other positions using the device 1 are possible. By way of example not shown in the figures, the user 8 can also take a rest position by resting his chin on the upper head holding portion 3 without placing his head in the upper opening 7. According to another example the user 8 can also use the device 1 as a lateral support device. The user can for example pass an arm through the two side openings. The device then has either its front portion or its rear portion disposed between the arm and the side portion of the bust of the user. Alternatively, the user can grip the device 1 with an arm, the latter being disposed between the arm and the lateral part of the bust of the user, the internal device being then deformed so that the internal space 2 is greatly reduced.

In addition, the device 1 may comprise other accessories not shown in the figures to facilitate the use of the device 1 in transport. As non-limiting examples, the device 1 may include a pocket for storing the personal effects of the user 8 when it wishes to rest. The device 1 may also comprise a fastening element, such as a ring, so that the user 8 can hang his glasses to the device 1 before adopting a rest position.
