The lining 132 of the headrest 13 covers at least the front surface 130 of the headrest 13 to provide comfort to the passenger of the seat 1. The headrest support 132 is made of metal or plastic, for example.
[0061] according to Figure 1 , Figure 2 and Figure 5 In the illustrated first embodiment of the present disclosure, the seat 1 includes an opening 14 disposed in a headrest support 132 between a backrest lining 122 and a headrest lining 133 .
[0062] According to the present disclosure, the opening 14 forms a recess for receiving the device 2. To this end, the headrest support 132 comprises a fastening system 140 for fastening said device 2, which is arranged in the opening 14 and is configured to removably fasten the device 2 in the recess.
[0063] According to a second embodiment of the present disclosure (not shown), the seat includes an opening arranged in the headrest lining, which forms a recess for accommodating a device, and the headrest lining includes a system for fastening the device, which is arranged in the opening and is configured to removably fasten the device to the recess.
[0064] By means of the recess thus formed, it is possible to removably mount a device in the vehicle seat 1 for the passengers, thereby improving their travel experience while limiting the space occupied by the device. As will be described in detail below, the device may be, for example, an electrical device, in particular an audio and / or video device, or a massage device, or a heating device, or a comfort device, such as a cushion or a support. Depending on the needs of the vehicle passengers, the mounted devices may be interchangeable.
[0065] According to the example shown, and in general, according to at least one embodiment, the recess formed by the opening 14 can have a complementary shape of an isosceles trapezoid with rounded edges in a longitudinal section along the plane YZ, with a large base and a small base each extending transversely along the direction Y, the large base being located on the lower edge side of the headrest 13 and the small base being located on the upper edge side of the headrest 13.
[0066] The small base has a first width, for example, between 10 cm and 25 cm, transversely along direction Y. The small base has a second width, for example, between 5 cm and 20 cm, transversely along direction Y. The height between the large base and the small base perpendicular to the large base is, for example, between 2 cm and 10 cm.
[0067] According to a variant, the recess may have any technically feasible shape and may, for example, have a shape complementary to a sphere, a parallelepiped or a portion of an irregular shape.
[0068] According to one embodiment, the opening 14 is a through hole. It is in particular accessible from the front surface 120, 130 of the backrest 12 or the headrest 13 and from the rear surface 121, 131 of the backrest 12 or the headrest 13. Alternatively, the opening 14 passes from a first lateral edge of the headrest 13 to a second lateral edge of the headrest 13.
[0069] According to another embodiment, the opening 14 is a blind opening. In particular, it is accessible only from the rear surface 121 of the backrest 12. In particular, the opening 14 is made blind by a flap. Alternatively, the opening 14 is accessible from the front surface 120 of the backrest 12 or the lateral edge of the headrest 13.
[0070] According to one embodiment, Figure 2As shown, the headrest support 132 comprises a first electrical connector 142 arranged in the opening 14, which is connected to a power source and / or a digital signal source of the vehicle for cooperating with a second electrical connector 207, 223 of the device 2, which will be described in further detail below. The first electrical connector 142 in particular protrudes into the opening 14. In particular, the first electrical connector 142 is centrally arranged on the side of the lower edge of the headrest 13. Alternatively, the first electrical connector 142 is arranged in any other conceivable position in the opening 14.
[0071] The digital signal source can be of various forms, especially audio or video.
[0072] According to one embodiment, the first electrical connector 142 comprises a first pole 143 for the power supply of the device 2, connected to the power supply, and a second pole 144 for the transmission of information between the device 2 and the vehicle, the first pole 143 being connected to the power supply, and the second pole 144 being connected to the digital signal source. Each pole 143, 144 is connected to the power supply and / or the digital signal source of the vehicle, in particular by means of a cable.
[0073] In particular, the first electrical connector 142 includes six poles, including two first poles 143 for powering the device 2 and four second poles 144 for information transmission between the device 2 and the vehicle. In particular, the first poles 143 and the second poles 144 of the first electrical connector 142 are aligned. In particular, the first poles 143 and the second poles 144 of the first electrical connector 142 are regularly spaced apart. As a variant, the poles have any other technically possible configuration.
[0074] according to Figure 2-4 In one embodiment shown, a fastening system 140 disposed in the opening 14 comprises a mechanical retaining portion 141 of the device 2. The mechanical retaining portion 141 is configured to block the device 2 in the opening 14 when the device 2 is inserted into the opening 14. Thus, the device 2 is held in place and does not risk falling onto a passenger during travel, for example, or falling onto the vehicle floor and damaging the vehicle floor.
[0075] The mechanical holding portion 141 in particular protrudes into the opening 14. In particular, the first electrical connector 141 is arranged centrally on the side of the lower edge of the headrest 13. Alternatively, the mechanical holding portion 141 is provided at any other conceivable position in the opening 14.
[0076] The mechanical holding portion 141 has, for example, an elongated rectangular shape protruding into the opening 14. As a variant, the mechanical holding portion 141 has any technically conceivable form.
[0077] According to an advantageous embodiment, the mechanical retaining portion 141 of the device 2 is movable relative to the headrest support 132 between a deployed position, in which it projects into the opening 14 and is configured to be locked in the locking cavity 206, 224 of the device 2 by ensuring the fastening of the device 2 housed in the opening 14, and a retracted position, in which the mechanical retaining portion 141 is retracted so as to be disengaged from the locking cavity 206, 224, thereby allowing the removal of the device 2.
[0078] Expand position as Figure 3 The mechanical holding portion 141 protrudes relative to the surface of the headrest support 132 in the vicinity of the mechanical holding portion.
[0079] Retracted position Figure 4 The mechanical retaining portion 141 is housed in a cavity 147 provided in the headrest support 132. In particular, in the retracted position, the mechanical retaining portion 141 has a surface that is flush with the surface of the headrest support 132 near the mechanical retaining portion. The deployment direction of the mechanical retaining portion 141 from the retracted position to the deployed position is generally oriented substantially transversely to the direction of insertion / extraction of the device into the recess formed by the opening 14.
[0080] According to one embodiment, the fastening system 140 also includes an elastic element 146 having a return force that pushes the mechanical retaining portion 141 from the retracted position to the deployed position, and a clamping system 145 that is configured to be manipulated by an operator to ensure that the mechanical retaining portion 141 overcomes the return force and passes from the deployed position to the retracted position.
[0081] The elastic element 146 is, for example, a spring, in particular a helical spring. The elastic element 146 is in particular fitted into the headrest support 132. Therefore, the elastic element 146 is not visible to the operator and is also protected from premature wear.
[0082] In the example shown, the clamping system 145 is directly connected to a first end of the elastic element 146, which is opposite to a second end of the elastic element 146 connected to the mechanical holding portion 141. The clamping system 145 comprises, for example, a strap, a tongue, a ring, a handle or any other conceivable clamping system.
[0083] Preferably, the fastening system 140 comprises means for locking the mechanical holding part 141 in its retracted position. For example, the locking means make it possible to lock the mechanical holding part 141 by means of a snap fastening. Manipulating the clamping system 145 makes it possible to release the mechanical holding part 141, whereupon the return force pushes the mechanical holding part from the retracted position to the deployed position. In other words, if the mechanical holding part 141 is in the deployed position, manipulating the clamping system 145, in particular pulling the clamping system 145, applies a force that resists the return force of the elastic element 146 and ensures that the mechanical holding part passes from the deployed position to the retracted position against the return force until it is locked by the locking means. The locking means holds the mechanical holding part 141 in the retracted position. Manipulating the clamping system 145 again, in particular pulling the clamping system 145, unlocks the locking means and releases the mechanical holding part 141, whereby the elastic element 146 returns to its deployed position.
[0084] according to Figure 2-4 In the advantageous embodiment shown, the first electrical connector 142 is arranged on the mechanical holding portion 141. With this configuration, the mechanical holding and the electrical connection of the device 2 are ensured by the same portion. The design is thus facilitated, and the insertion of the device 2 into the opening 14 and the connection of the device 2 via the first electrical connector 142 can be accomplished in a single gesture.
[0085] In particular, said elastic element 146 constraining the mechanical retaining portion 141 to the deployed position is configured to ensure electrical contact between the first electrical connector 142 of the headrest 132 and the second electrical connector 207 of the device 2 .
[0086] According to one embodiment, an example is shown as follows Figure 5 As shown, the seat 1 also comprises a piece of equipment 2 housed in an opening 14 of the upper part 11 of the seat 1 .
[0087] The device 2 comprises a body 201, 222 having a shape complementary to the opening 14 so as to be housed in the recess by interlocking. In the case shown, when at least a portion of the body of the device 2 is housed in the recess, it has, in longitudinal section along the plane YZ, the complementary shape of an isosceles trapezoid with rounded edges.
[0088] According to a variant, the body of the device may have any other shape capable of being housed in the recess without being complementary thereto.
[0089] The body 201 , 222 of the device 2 may further comprise at least one stop surface configured to stop the device during insertion of the device into the recess.
[0090] According to one embodiment, the body 201, 222 has a locking cavity 206, 224 configured to lock the mechanical retaining portion 141 when the device 2 is inserted into the opening 14. The locking cavity 206, 224 advantageously has a shape complementary to the mechanical retaining portion 141 so that the mechanical retaining portion 142 can be fitted into the locking cavities 206 and 224.
[0091] Advantageously, the device 2 comprises a holding device 20 to facilitate its removal when inserted into the recess. The holding device 20 comprises, for example, a strap, a tongue, a ring, a handle or any other conceivable holding device. The holding device 20 is placed on the device 2 so that it can be accessed from the outside of the recess when the device 2 is received in the recess. According to the example shown, the holding device 20 is a belt, so that an operator who performs a pulling movement on the belt can remove the device 2 from the recess. Preferably, before removing the device 2 from the opening 14, the operator moves the mechanical retaining portion 141 as described above from the deployed position to the retracted position, in which the mechanical retaining portion 141 is retracted so as to disengage from the locking cavity 206, 224, thereby allowing the device 2 to be removed.
[0092] According to one embodiment, the device 2 is an electrical device 200 comprising a second electrical connector 207 configured to connect to the first electrical connector 142 of the headrest support 132 at a location of the device 2 received in the opening 14 .
[0093] In particular, the second electrical connector 207 includes poles that are respectively configured to be electrically connected to the poles 143, 144 of the first electrical connector 142. In particular, the second electrical connector 207 includes six poles. In particular, the poles of the second electrical connector 207 are aligned. In particular, the poles of the second electrical connector 207 are regularly spaced apart. Alternatively, the poles of the second electrical connector 207 have different configurations but are still electrically connected to the poles 143, 144 of the first electrical connector 142.
[0094] The second electrical connector 207 is placed in the locking cavity 204 of the electrical device 200 , for example.
[0095] According to one embodiment, the electrical device 200 is an audio and / or video device including a screen and / or speakers, and wherein the first electrical connector 142 and the second electrical connector 207 provide connection and power supply for the device and transmission of digital audio and / or video signals.
[0096] According to a preferred embodiment of the present disclosure, Figure 6 and Figure 7 The electrical device shown is a portable audio speaker 200 .
[0097] The speaker 200 has a main body 201, which is shaped like Figure 2 14 is complementary to the opening 14 visible in the figure. The body 201 of the loudspeaker 200 has a front surface 204 and a rear surface 202 opposite to the front surface 204. When the loudspeaker 200 is inserted into the opening 14, at least the rear surface 202 is accessible to the operator. The front surface 204 and the rear surface 202 are connected together by a circumferential wall 203. The front surface 204 and the rear surface 202 and the circumferential wall 203 define the internal volume of the loudspeaker 200, in which a loudspeaker (not shown) is provided. The front surface 204 advantageously has a perforated surface 205 to allow sound diffused by the loudspeaker to pass. The clamping band 210 is attached to the rear surface 202 of the loudspeaker 200. In the lower part, the circumferential wall 203 defines a locking cavity 204. The locking cavity 204 has a shape complementary to the mechanical retaining portion 141, so that when the loudspeaker 200 is inserted into the opening 14, the mechanical retaining portion 141 can be assembled into the locking cavity 206. The second electrical connector 207 is placed in the locking cavity 204 of the electrical device 200 .
[0098] Advantageously, the loudspeaker 200 may further comprise a battery, in particular contained within the internal volume defined by the front and rear surfaces 204 , 202 and the peripheral wall 203 .
[0099] Thus, generally, the loudspeaker 200 may enable it to broadcast a sound signal:
[0100] - when the device, namely the loudspeaker 200, is housed in the opening, the first electrical connector 142 and the second electrical connector 207 are then connected, ensuring in particular the transmission of digital audio signals to the loudspeaker, as well as powering of the device, or even recharging of the battery (optional), when the loudspeaker is provided with said battery,
[0101] When the device is removed from the opening 14 , by means of the electrical energy of the battery, in particular by means of a wireless transmission system, in particular according to a telecommunication protocol, for example according to the Bluetooth communication standard.
[0102] Therefore, when the speaker 200 is received in the opening 14, the second electrical connector 207 is electrically connected to the first electrical connector 142. The transmission of digital audio signals between the audio digital signal source of the vehicle and the speaker 200 enables the digital audio signals to be broadcast through the speakers of the speaker 200, thereby improving the sound experience of the vehicle passengers. In particular, the control unit of the vehicle, whether connected or not to the display device, can control the audio digital signals broadcast by the speaker.
[0103] Alternatively or additionally, the loudspeaker 200 is capable of communicating with a device according to a remote communication protocol. For example, the loudspeaker is capable of communicating via ultra-high frequency radio waves, in particular according to the Bluetooth protocol in a frequency band between 2.402 GHz and 2.480 GHz. Thus, the operator can remotely control the loudspeaker 200 using any device capable of transmitting digital audio signals via said remote communication protocol, for example from a smartphone. When the loudspeaker 200 is advantageously equipped with a battery, it can be used independently of the seat 1, like any portable audio speaker.
[0104] According to a variant of the device, in particular an electrical device, the device can be used for the comfort of the occupant or occupants of the seat 1, such as a heating electrical device or a massage device, or a support lining in particular for neck support. In this case, the opening is opened at least on the front surface side of the backrest, so that the comfort part of the comfort device (mass and / or heating and / or support lining) protrudes from the opening on the front surface side, arranged opposite the area of the occupant to be treated (usually in the neck or nape of the neck).
[0105] according to Figure 8 In another embodiment shown, the device 2 is a support 220 comprising means 226 for supporting a tablet 225, or more generally a screen protruding from the seat 1, which is located on the rear surface 121 of the backrest 12, opposite the front surface 120 of the backrest 12, which accommodates the upper part of the body of the occupant of the seat 1. Tablet refers to a digital, electronic or touch screen tablet, usually in the form of a touch-activated screen.
[0106] The support member 220 has a main body 221, and the shape of the main body 221 is similar to Figure 2 The body 221 of the support 220 has a rear surface 221, and the plate 225 support device 226 is opposite to the rear surface 221. The rear surface 221 and the plate 225 support device 226 are connected to each other by a circumferential wall 222. In the lower part, the circumferential wall 222 defines a locking cavity 224. The locking cavity 224 has a shape complementary to the mechanical retaining portion 141, so that when the support 220 is inserted into the opening 14, the mechanical retaining portion 141 can be assembled into the locking cavity 224.
[0107] The locking cavity 224 may in particular be provided with a pole 223 configured to cooperate with the poles 143, 144 of the first electrical connector 142. In this particular embodiment, the first electrical connector 142 enables the support 220 to be locked in place in the opening 14, preferably by establishing an electrical contact. Such an electrical contact may in particular allow the screen or tablet to be powered by an electrical connection to the energy source of the vehicle, or even allow the battery of the tablet to be recharged, or even allow the audio / video system of the vehicle to be connected to the tablet / screen by wire. The support 220 also has a stop surface 228, which is configured to stop the support 220 during the insertion of the support 220 into the recess. The stop surface 228 is, for example, located on a protrusion between the body 221 of the support 220 and the tablet support 226 along the lower part of the circumferential wall 222. Thus, when the support 200 is inserted into the opening 14, the stop surface protrudes from the opening 14 and prevents the insertion of the support 220 too far from the opening 14. The plate support means 226 allow the fastening of the plate 225, for example by means of suction cups, or by means of stops enclosing the plate 225, or any other reversible fastening means.
[0108] By means of the support 220, a passenger sitting behind the seat 1 can use a tablet while sitting comfortably with both hands free.
[0109] according to Fig. 9 In another embodiment shown, the device 2 is a support including a cushion and / or a neck support pad protruding from the seat 1, located on the front surface 120 of the backrest 12, for accommodating the upper body of the occupant of the seat 1. Thus, the occupant of the seat 1 can removably attach the neck support pad in the opening 14 and improve its comfort. The neck support may include a U-shaped support profile to accommodate the nape and / or neck of the occupant of the seat.
