Description

BACKGROUND OF THE INVENTION The invention relates to a passenger accessory, in particular for an air passenger. The invention relates more specifically to an accessory for isolating a passenger from the rest of the environment in which it is located. State of the art When traveling, passengers, including air transport, can suffer from promiscuity resulting from the proximity of other passengers and therefore a lack of privacy. In the transport type airliner or train, this promiscuity is all the more important that to gain space, passenger seats are relatively close to each other. This problem is clearly evident in the context of air transport. While the layout and comfort of first-class and business class seats allow passengers to easily isolate themselves, the same can not be said for economy class.

There are already isolation devices that aim to overcome these disadvantages. For example, it is common to isolate oneself from the sound environment by means of ear plugs or by listening to music with headphones.

As far as the visual field is concerned, sleep masks are widely used, especially in airplanes.

However, passengers, even wearing such devices, always expose themselves to the eyes of others, even though some may feel they are not fully to their advantage during the trip, and in particular on occasion long haul flights where passengers will often fall asleep at one time or another. General presentation of the invention An object of the invention is to overcome these problems of promiscuity and lack of privacy. For this purpose, there is provided a removable accessory for passenger comprising: a deployable device between a compact transport position and an extended position, said device being, in a compact transport position, a dimensioning allowing easy storage in a luggage to hand and being when deployed, able to cover the entire face of a seat passenger to isolate it from the eyes of other passengers, means adapted to ensure the removable attachment of this deployable device on the upper part forming headrest of a passenger seat. The invention is advantageously complemented by the following features, taken alone or in any of their technically possible combinations: the means adapted to ensure the removable attachment of this deployable device comprise at least one fastener capable of pinching the passenger seat; the means adapted to secure the attachment comprise at least one strap enclosing the passenger seat, - support means of the head of the seat passenger, adapted to prevent a tilting of the head of the passenger to the front, - the means of support of the head of the seat passenger comprises at least two branches adapted to extend on both sides of the passenger's head and to come each in contact with the passenger's face, - the areas of the branches in contact with the passenger face are foam, - the deployable device comprises several arches deployable in rotation relative to a common axis, - the arcs are sensibl in the form of a moon, - an arc comprises means for locking the deployable device in the second deployed position, - the deployable device comprises a web extending between rigid arches, the fabric being adapted to be folded when the deployable device is in position. compact and unfolded position when the deployable device is in the deployed position, the rigid arcs being adapted to be close together when the deployable device is in compact position and remote when the deployable device is in the deployed position.

In the accompanying drawings: FIGS. 1a to 1d represent different views of an example of an accessory illustrating a first embodiment of the invention; FIGS. 2a to 2d represent different views of an example of an accessory illustrating a second Embodiment of the invention, - Figures 3a and 3b show two details of exemplary embodiments of a deployable device of an accessory according to the invention.

Description of the Invention Example of an Accessory Illustrating a First Embodiment Deployable Device With reference to FIGS. 1a to 1d, there is described a removable accessory 1 for a passenger 3, for example for a passenger 3 of an aircraft. The passenger 3 is for example installed in a seat 2 passenger economy class of a plane. The accessory 1 comprises a device 13 deployable between a compact transport position and an extended position. The removable accessory 1 further comprises means 11 adapted to ensure the removable attachment of this deployable device 13 on the upper part forming a headrest of the passenger seat 2.

In compact transport position, the deployable device 13 is of a size allowing easy storage of the accessory 1 in a hand luggage. Thus the accessory 1 can be transported by the passenger during his travels. The accessory 1 can be stored in a bag for distribution or sale to the passenger 3, for example in an airport or on the plane. When the accessory 1 is fixed to the seat 2 by the removable attachment means 11, the deployable device 13 can be deployed to cover the entire face of the passenger 3 of the seat 2. The deployable device 13 is thus an isolation device which allows the passenger 3 to isolate himself from other passengers' eyes. The deployable device 13 is adjustable in height and depth relative to the seat back 2 by adjustment means. The adjustment means may comprise any means known to those skilled in the art, for example telescopic arms. Thus the device 13 can be placed optimally according to each passenger 3.

The deployable device 13 shown in FIGS. 1a to 1d comprises several arcs 131 deployable in rotation with respect to a common axis A. When the accessory 1 is fixed to the seat 2 by the means 11 for removable attachment, the axis A has a direction substantially parallel to a backrest and a seat of the seat 2. Note that this direction is substantially orthogonal to the main plane of symmetry of the face of the passenger 3. The arches 131 are connected at their ends to the means 11 of removable attachment, the A.30 axis of rotation According to an embodiment illustrated in Figure 3a, the arches 131 are substantially moon-shaped. By moon we mean a corresponding surface in spherical geometry to a non-degenerate digone whose vertices are antipodal. The arches 131 may for example be made of polymer material. The arches 131 may be inserted into each other as illustrated at the area 61 to allow the deployable device 13 to reach a compact transport position. The arches 131 are hinged to each other and can therefore be separated from one another as illustrated at the area 62 to allow the deployable device 13 to assume a deployed position. In the deployed position, the arches 131 are in contact only at the sides of the moons. An arc 131 may comprise locking means of the deployable device 13 in the second deployed position. It may be a fastening device to another element of the accessory 1, for example to a member of the means 11 for removable attachment, or a locking system at the axis of rotation A of the arches 131. Figures 1a to 1d represent different views of the accessory 1 fixed by the means 11 adapted to ensure the removable attachment of the deployable device 13 to an aircraft seat 2 on which is installed the passenger 3. FIGS. , respectively 1b, represent a profile view, respectively front, of the accessory 1 whose deployable device 13 is in compact position. The arches 131 are gathered above the passenger's head 3, their ends being located on either side of the passenger's head. In this position, the arches 131 do not limit the field of view of the passenger 3. Figure lc shows the same accessory 1 whose deployable device 13 is partially deployed between the compact position and the deployed position. Several arcs 131 are visible and are in contact with each other.

Figure 1d shows the same accessory 1, the deployable device 13 being in the deployed position. The passenger's face 3 is completely covered by the deployable device 13. The deployable device 13 being opaque, the passenger 3 is visually isolated from the outside environment and from any light source. Furthermore, the head of the passenger 3 being held by means 12 of support, it will not change position and will not be hindered by the device 13 deployed. The space between the face of the passenger 3 and the device 13 deployed is important enough to avoid any feeling of suffocation for the passenger 3 and to ensure comfort. The dimensions of the space can be modified by adjusting in height and depth the deployable device 13. Similarly, other passengers can no longer see the head or face of the passenger 3. The passenger 3 can rest without risk of being at a disadvantage vis-à-vis people around him. Removable means of attachment The removable attachment means 11 may comprise any means adapted to attach the accessory 1 to the seat 3. The accessory 1 is not part of the seat 2. Thus, if the seat 2 comprises a headrest, the Accessory 1 may comprise means 11 adapted to ensure the removable attachment to the headrest of the seat 2. The introduction of the accessory 1 on the seat or its removal is a simple way so that a passenger 3 can achieve them alone and in a limited time. The passenger 3 does not need to change the architecture of the seat 3. In particular, the passenger 3 does not have to remove or replace a seat element 2.30 In the example shown in Figures la to 1 d, the means 11 for removable attachment comprise a first strap 112 enclosing the passenger seat 2 at the headrest portion of the seat 2. In Figures 1a-1d, the first strap 112 surrounds the periphery of the support head of the seat 2. The arches 131 are connected to the fastening means 11 at the level of the first strap 112, on either side of the seat 2, at the axis of rotation A of the arches 131. removable attachment may comprise a second strap 113 to ensure better attachment of the accessory 1. The second strap 113 extends firstly on the front of the backrest or the headrest of the seat 2 and other on the back of the seat backrest or headrest 2. The second strap 113 thus connects Opposite portions of the first strap 112. In this manner, the second strap 113 provides better vertical support of the accessory 1 and better attachment to the seat 2. The straps are adjustable in length to allow effective attachment and adapt 2. The means 11 for removable attachment can be used to attach the accessory 1 to seats 2 with or without headrest, of different widths, thicknesses and heights.

The removable attachment means 11 can also be adapted to fix the accessory 1 at different heights of the seat 2 to adapt to the size of the passenger 3. Supporting means The accessory 1 comprises means 12 for supporting the head of the passenger 3 of the seat 2, adapted to prevent a tilting of the head of the passenger 3 forward. In the example shown in FIGS. 1a to 1d, the means 30 for supporting the passenger's head 3 of the seat 2 comprise two branches 121 and 122 adapted to extend on either side of the passenger's head. 3 and to each come into contact with the passenger's face 3. The branches 121 and 122 are connected to the removable fixing means 11 in order to be able to support the passenger's head 3, in particular if it falls asleep and its head risk of tipping forward or sideways. The branches 121 and 122 can be adapted to the passenger's face 3. The branches 121 and 122 are extensible so that they can be adjusted in length. The height of the branches can be modified by means of movement at the branches 121 and 122 or by the attachment means 11. The branches 121 and 122 support the head of the passenger 3 by coming into contact with his face, for example at the level cheeks or cheekbones of the passenger 3. Each branch 121, respectively 122, comprises a piece 123, respectively 124, made of foam adapted to come into contact with the passenger's face 3. The pieces 123 and 124 foam prevent that branches 121 and 122 can not injure the passenger 3. These pieces 123 and 124 foam provide passenger comfort 3 when the accessory 1 is in place.

The support means 12 prevent any tilting of the head, in particular an involuntary tilting during sleep. The support means 12 allow the passenger 3 to avoid any uncomfortable position, for example a position that can generate muscle soreness. The means 12 of support avoid the passenger 3 to find himself involuntarily in a position that would not be to his advantage. Such a position is for example a position where the passenger 3, while sleeping, is too close to another passenger, or a position deemed unsightly by the passenger 2. The support means 12 can be adjusted in height and deep in relation to the seat 2.

The accessory 1 can be arranged in a compact transport position in which it has a small space requirement. In this position, the deployable device 13 is itself in a compact position. The means 12 for supporting the head and the deployable device 13 are arranged substantially in the same plane. Indeed, the deployable device 13 is placed so that with respect to its axis of rotation A that it is at the same level as the branches 121 and 122. In the second transport position, the accessory can be stored in a bag to be easily transported or distributed.

Figures 2a, respectively 2b, show a side view, respectively front view of the accessory 1 whose deployable device 13 is in a compact position. The arches 131 are joined to one side of the passenger's head 3. Figure 2c shows the same accessory 1, the deployable device 13 being in the deployed position. In this example, the support means 12 are adapted so that the head of the passenger 3 comes to rest on it. Such support means 12 may comprise two foam branches 121 and 122. The head of the passenger 3 comes to rest on the branches 121 and 122. The branches 121 and 122 also extend in such a way that they are in contact with the cheeks of the passenger 3 and prevent lateral tilting of the head. The deployable device 13 is articulated along an axis A of rotation substantially orthogonal to the seat seat 2 and substantially parallel to the seat back 2. The deployable device 13 is hinged relative to the fastening means 11 by a suspension arm 133. The suspension arm 133 is adapted to extend from the top of the seat headrest 2 to a point above the passenger's head 3. The arches 131 are connected only by one of their ends to the arm 133 of their suspension, their lower extremities being left free. The suspension arm 133 can be hinged to allow the position of the deployable device 13 to be adjusted. In this example, the arches 131 extend laterally around the passenger's head 2.

Figure 2d shows another example of accessory 1 according to the second embodiment. The accessory 1 differs from that shown in Figures 2a to 2c in that the support means 12 comprise a cushion adapted to be placed at the level of the passenger's neck 3, cushion on which is supported and rest the passenger's head 3. The cushion has two branches that extend on either side of the neck and a lower portion of the passenger's face 3, the two branches being connected by a rear section. The cushion is attached to the means 11 for removable attachment at its rear section. The cushion may for example be foam or be inflatable.

Furthermore, the accessory 1 of Figure 2d differs from that shown in Figures 2a to 2c in that the means 11 for removable attachment include fasteners 111 adapted to come to pinch the passenger seat 2. In this example, the fasteners 111 consist of nipping arms whose spacing may be modified by spacing means to adapt to the dimensions of the seat 2.
