Description
Appui-tête doté d'au moins un haut-parleur, siège de véhicule comportant un tel appui-tête et ensemble audio incluant un tel appui-tête.Headrest provided with at least one loudspeaker, vehicle seat comprising such a headrest and audio assembly including such a headrest.
La présente invention est relative aux appuis-tête dotés de haut-parleurs, aux sièges de véhicules comportant de tels appuis-tête et aux ensembles audio incluant de tels appuis-tête. The present invention relates to head restraints fitted with loudspeakers, to vehicle seats comprising such head restraints and to audio assemblies including such head restraints.
Plus particulièrement, l'invention concerne un appui-tête pour siège de véhicule, comportant un circuit électrique qui inclut au moins un haut-parleur, tel que divulgué par exemple dans le document GB-A-2 102 656. More particularly, the invention relates to a headrest for a vehicle seat, comprising an electrical circuit which includes at least one loudspeaker, as disclosed for example in document GB-A-2 102 656.
L'appui-tête décrit dans ce document est alimenté par des fils électriques qui passent dans les broches de support de cet appui-tête, ce qui complique notablement le montage dudit appui-tête et augmente son prix de revient, en particulier si la position de l'appui-tête doit pouvoir être réglée. The headrest described in this document is powered by electric wires which pass through the support pins of this headrest, which notably complicates the mounting of said headrest and increases its cost price, in particular if the position of the headrest must be adjustable.
De plus, lorsque l'appui-tête d'un tel siège est amovible, l'enlèvement de cet appui-tête est complexe, dans la mesure où il est nécessaire de déconnecter les haut-parleurs en même temps qu'on enlève l'appui-tête, faute de quoi les connexions des haut-parleurs seraient abîmées. In addition, when the headrest of such a seat is removable, the removal of this headrest is complex, since it is necessary to disconnect the speakers at the same time as removing the headrest, otherwise the speaker connections would be damaged.
La présente invention a notamment pour but de pallier à ces inconvénients. The present invention aims in particular to overcome these drawbacks.
A cet effet, selon l'invention, un appui-tête du genre en question est essentiellement caractérisé en ce que le circuit électrique de l'appui-tête ne présente aucune liaison électrique filaire avec l'extérieur de l'appui-tête, et en ce que ce circuit électrique inclut en ou tre un circuit de réception radio qui est adapté pour recevoir des signaux radio et pour faire émettre par le haut-parleur des signaux sonores correspondant auxdits signaux radio. To this end, according to the invention, a headrest of the kind in question is essentially characterized in that the electrical circuit of the headrest has no wired electrical connection with the outside of the headrest, and in that this electric circuit includes in or of a radio reception circuit which is adapted to receive radio signals and to cause the loudspeaker to emit sound signals corresponding to said radio signals.
Grâce à ces dispositions, il n'est plus nécessaire d'avoir recours à des montages complexes pour le passage des fils électriques d'alimentation des haut-parleurs, puisque ces fils sont supprimés. Thanks to these provisions, it is no longer necessary to have recourse to complex assemblies for the passage of the electric wires supplying the loudspeakers, since these wires are eliminated.
De plus, lorsque l'appui-tête d'un tel siège est amovible, l'enlèvement de cet appui-tête est simple et ne risque pas d'endommager les connexions des haut-parleurs. In addition, when the headrest of such a seat is removable, the removal of this headrest is simple and does not risk damaging the speaker connections.
On peut ainsi le cas échéant déplacer l'appui-tête muni de haut-parleurs d'un siège à l'autre, ce qui est particulièrement intéressant lorsque cet appui-tête est destiné à diffuser de la musique ou des émissions radiophoniques en provenance d'un autoradio, d'un lecteur de cassettes ou d'un lecteur de disques optiques. It is thus possible, if necessary, to move the headrest provided with loudspeakers from one seat to another, which is particularly advantageous when this headrest is intended for broadcasting music or radio broadcasts from car radio, cassette player or optical disc player.
Dans des modes de réalisation préférés de l'invention, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivantes
- le circuit électrique de l'appui-tête comporte en outre un dispositif d'alimentation électrique autonome qui alimente le circuit de réception radio
- le circuit électrique de l'appui-tête comporte en outre un amplificateur entre le circuit de réception radio et le haut-parleur
- le circuit de réception radio est adapté pour recevoir des signaux radio HF ;
- l'appui-tête comprend une face avant dotée d'une partie centrale destinée à servir d'appui pour la tête d'un utilisateur, et le circuit électrique de l'appui-tête comprend deux haut-parleurs disposés sur ladite face avant de l'appui-tête, de part et d'autre de la partie centrale de cette face avant.In preferred embodiments of the invention, use may optionally be made of one and / or the other of the following provisions.
- the electrical circuit of the headrest also includes an autonomous electrical supply device which supplies the radio reception circuit
- the electrical circuit of the headrest also includes an amplifier between the radio reception circuit and the loudspeaker
- the radio reception circuit is adapted to receive HF radio signals;
the headrest comprises a front face provided with a central part intended to serve as a support for the head of a user, and the electrical circuit of the headrest comprises two speakers arranged on said front face of the headrest, on either side of the central part of this front face.
Par ailleurs, l'invention a également pour objet un siège de véhicule comportant une assise et un dossier qui porte un appui-tête tel que défini ci-dessus, cet appui-tête étant le cas échéant amovible. Furthermore, the invention also relates to a vehicle seat comprising a seat and a backrest which carries a headrest as defined above, this headrest being optionally removable.
Enfin, l'invention a encore pour objet un ensemble audio comprenant, d'une part, un appui-tête tel que défini ci-dessus, et d'autre part, un système central qui est destiné à être solidarisé avec la caisse du véhicule et qui comporte un circuit d'émission radio adapté pour émettre lesdits signaux radio vers l'appui-tête. Finally, the invention also relates to an audio assembly comprising, on the one hand, a headrest as defined above, and on the other hand, a central system which is intended to be secured to the body of the vehicle and which comprises a radio transmission circuit adapted to transmit said radio signals to the headrest.
Avantageusement, ledit système central est choisi parmi les autoradios, les lecteurs de cassettes à bande magnétique et les lecteurs de disques optiques. Advantageously, said central system is chosen from car radios, magnetic tape cassette players and optical disc players.
Ledit système central peut aussi être un radiotéléphone comportant une unité centrale électronique reliée au moins audit circuit d'émission radio, à un microphone, et à un circuit d'émission et de réception radio adapté pour communiquer avec l'extérieur du véhicule. Said central system can also be a radiotelephone comprising an electronic central unit connected at least to said radio transmission circuit, to a microphone, and to a radio transmission and reception circuit adapted to communicate with the exterior of the vehicle.
D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description suivante d'une de ses formes de réalisation, donnée à titre d'exemple non limitatif, en regard des dessins joints. Other characteristics and advantages of the invention will appear during the following description of one of its embodiments, given by way of nonlimiting example, with reference to the accompanying drawings.
Sur les dessins
- la figure I est une vue en perspective d'un siège incluant un appui-tête selon une forme de réalisation de l'invention,
- et la figure 2 est un schéma de principe d'un ensemble audio incluant l'appui-tête du siège de la figure 1. On the drawings
FIG. I is a perspective view of a seat including a headrest according to an embodiment of the invention,
- And Figure 2 is a block diagram of an audio assembly including the headrest of the seat of Figure 1.
Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires. In the different figures, the same references designate identical or similar elements.
La figure 1 représente un siège 1 de véhicule, notamment un siège avant de véhicule automobile, qui comporte une assise 2 sur laquelle est monté un dossier 3. FIG. 1 represents a seat 1 of a vehicle, in particular a front seat of a motor vehicle, which comprises a seat 2 on which a backrest 3 is mounted.
Ce dossier 3 s'étend vers le haut depuis l'assise 2 jusqu'à une partie supérieure 4 qui porte un appui-tête 5, par exemple par l'intermédiaire de deux broches coulissantes 6 permettant de régler la hauteur de l'appui-tête et le cas échéant d'enlever cet appui-tête. This file 3 extends upwards from the seat 2 to an upper part 4 which carries a headrest 5, for example by means of two sliding pins 6 making it possible to adjust the height of the support- head and if necessary remove this headrest.
L'appui-tête 5 présente une face avant 7 dotée d'une partie centrale 8 qui est adaptée pour servir d'appui à la tête d'un utilisateur et qui est encadrée par deux haut-parleurs 9 affleurant sur ladite face avant 7. The headrest 5 has a front face 7 provided with a central part 8 which is adapted to serve as support for the head of a user and which is framed by two speakers 9 flush with said front face 7.
Bien entendu, l'appui-tête 5 pourrait comporter un nombre de haut-parleurs différent de deux, et ces hautparleurs pourraient être disposés différemment, bien que la disposition représentée sur la figure 1 soit préférée. Of course, the headrest 5 could include a number of speakers other than two, and these speakers could be arranged differently, although the arrangement shown in Figure 1 is preferred.
Comme représenté sur la figure 2, les deux hautparleurs 9 font partie d'un circuit électrique 10 qui luimême appartient à un ensemble audio 11 comprenant, d'une part, le circuit 10, et d'autre part, un système central fixe 12,25 qui comprend de préférence
- un autoradio 25 (éventuellement associé à ou remplacé par un système de lecture d'enregistrements sonores tel que lecteur de cassettes à bande magnétique ou lecteur de disques optiques),
- et le cas échéant, un radiotéléphone 12 notamment de type "mains libres.As shown in FIG. 2, the two speakers 9 are part of an electrical circuit 10 which itself belongs to an audio assembly 11 comprising, on the one hand, the circuit 10, and on the other hand, a fixed central system 12, 25 which preferably includes
- a car radio 25 (possibly associated with or replaced by a system for playing sound recordings such as magnetic tape cassette player or optical disc player),
- And if necessary, a radiotelephone 12, in particular of the "hands-free" type.
Le circuit électrique 10 est entièrement autonome et tout entier contenu à l'intérieur de l'appui-tête 5, ce circuit ne présentant aucune liaison électrique filaire avec l'extérieur de l'appui-tête. The electrical circuit 10 is entirely autonomous and entirely contained within the headrest 5, this circuit having no wired electrical connection with the exterior of the headrest.
Plus précisément, le circuit électrique 10 comprend
- un dispositif d'alimentation électrique autonome 13 tel qu'une pile ou une batterie rechargeable,
- un circuit de réception radio constitué d'un récepteur 14 associé à une antenne 15, ce circuit de réception radio étant adapté pour recevoir des signaux radio haute fréquence (HF),
- et un amplificateur 16 qui relie le circuit de réception radio 14,15, aux deux haut-parleurs 9, de façon que ces haut-parleurs émettent des signaux sonores correspondant aux signaux radio reçus.More specifically, the electrical circuit 10 comprises
an autonomous electrical supply device 13 such as a battery or a rechargeable battery,
a radio reception circuit consisting of a receiver 14 associated with an antenna 15, this radio reception circuit being adapted to receive high frequency radio signals (HF),
- And an amplifier 16 which connects the radio reception circuit 14,15, to the two loudspeakers 9, so that these loudspeakers emit sound signals corresponding to the radio signals received.
L'autoradio 25, quant à lui, comporte un système de réception 26 permettant de recevoir des émissions radiophoniques, le système d'émission étant relié à un circuit d'émission radio comprenant un émetteur 27 associé à une antenne 28 adaptée pour émettre les signaux radio susmentionnés vers l'appui-tête, de façon que les émissions radiophoniques reçues par l'autoradio soient retransmises par l'intermédiaire des haut-parleurs 9. The radio 25, meanwhile, includes a reception system 26 for receiving radio broadcasts, the transmission system being connected to a radio transmission circuit comprising a transmitter 27 associated with an antenna 28 adapted to transmit the signals radio above towards the headrest, so that the radio broadcasts received by the car radio are retransmitted via the speakers 9.
Par ailleurs, le radiotéléphone 12, qui peut être fixé notamment au tableau de bord du véhicule, comporte une unité centrale électronique 17 qui est reliée par exemple
- à un circuit d'émission radio comprenant un émetteur 18 associé à une antenne 19 adaptée pour émettre les signaux radio susmentionnés vers l'appui-tête,
- à un microphone 20,
- à un circuit d'émission et de réception radio comprenant un émetteur-récepteur 21 associé à une antenne 22 pour communiquer avec des stations de base fixes d'un réseau de radiotéléphone à l'extérieur du véhicule,
- à un clavier 23,
- et à un écran 24.Furthermore, the radiotelephone 12, which can be fixed in particular to the dashboard of the vehicle, comprises an electronic central unit 17 which is connected for example
- a radio transmission circuit comprising a transmitter 18 associated with an antenna 19 adapted to transmit the above-mentioned radio signals to the headrest,
- to a microphone 20,
- a radio transmission and reception circuit comprising a transceiver 21 associated with an antenna 22 for communicating with fixed base stations of a radiotelephone network outside the vehicle,
- to a keyboard 23,
- and a screen 24.
Ainsi, lorsque le passager du siège 1 utilise le radiotéléphone 12 pour converser avec un interlocuteur, l'unité centrale 17 fait émettre par le circuit d'émission radio 18,19 des signaux radio correspondant à la voix de l'interlocuteur, et ces signaux radio sont reçus par le circuit de réception radio 14,15 puis émis sous forme de signaux sonores par les haut-parleurs 9, qui reproduisent la voix de l'interlocuteur. Thus, when the passenger in seat 1 uses the radiotelephone 12 to converse with an interlocutor, the central unit 17 causes the radio transmission circuit 18,19 to transmit radio signals corresponding to the voice of the interlocutor, and these signals radio are received by the radio reception circuit 14,15 then emitted in the form of sound signals by the speakers 9, which reproduce the voice of the interlocutor.
