- the second end 42 can be inserted into a housing 44 formed on the rocker 26.
- the rocker 26 has a stable equilibrium position corresponding to the unlocking position.
- the seat 1 may comprise a locking member 46.
- the locking member 46 is movable relative to the seat 1, for example in rotation around a pivot connection P2, between a locking position, visible on the figures 3 and 5 , and an unblocking position, visible on the figures 2 and 4 .
- the locking member 46 makes it possible to block the rocker 26 in the locked position.
- unlocking position the locking member 46 allows the rotation of the rocker 26 so that it leaves the locking position.
- the locking member 46 is here attached to the rod 14 of the electromagnet 12, so that the displacement of the rod 14 causes the simultaneous movement of the locking member 46.
- the locking member 46 when the rod 14 is in the first position, the locking member 46 is in the locking position, whereas when the rod 14 is in the second position, the locking member 46 is in the unlocking position.
- the locking member 46 may comprise an end 48 intended to impede the path described by an abutment member 50 when the latch 26 is moved to the unlocking position.
- the abutment member 50 is here attached to a second end 52 of the flip-flop 26, the second end 52 being arranged opposite to the first end 28.
- the locking member 46 may be substantially rectilinear, and its axis of rotation relative to the seat 1 may be arranged on or in the vicinity of a tangent 54 at a point M to the circle 56 described by the stop member 50 when the rocker 26 pivots relative to the seat 1, the point M corresponding to a point of this stop member 50 when the latch 26 is in the locking position.
- the electromagnet 12 may comprise two stops 58 arranged to stop the rotation of the locking member 46 when the latter, moved by the rod 14, reaches the locking position and the unlocking position.
- the guardrail locking system 10 is disarmed; the railing 10 can be freely moved between the raised position and the lowered position.
- the electromagnet 12 When the seat 1 reaches the entrance to a boarding area 106, the electromagnet 12 is supplied with electricity via the electrical conductors 22, 24, so that the rod 14 is moved to the first stable position, which causes the displacement of the blocking member 46 to the blocking position. More specifically, an electric pulse is applied to the electrical poles of the first coil 16. In this situation, the guardrail locking system 10 is armed.
- the guardrail member 17 abuts against the second functional surface 32, and causes the rocker 26 in a rotational movement towards the locking position of the rocker 26.
- the second end 52 of the rocker 26 bears against the blocking member 46 by pushing it slightly before being positioned just above the end 48 of the blocking member 46. the last being repelled by the rod 14 maintained tending to remain in the first stable position.
- the blocking member 46 thus acts in the manner of a non-return catch.
- the first functional surface 30 is positioned behind the railing element 17, which it traps in the housing 34, hindering the return path of the railing element 17.
- the latch 26 is then immobilized in the locking position.
- the guardrail 10 is in turn locked in the lowered position.
- the electromagnet 12 When the seat 1 reaches an unloading zone 108, the electromagnet 12 is electrically powered via the electrical conductors 22, 24, which causes the rod 14 to move from the first position to the second stable position, and consequently that of the locking member 46 to the unlocking position. More specifically, when the seat 1 reaches an unloading area 108, the second reel 18 is powered to move the rod 14 to the second position and thus disarm the guardrail lock 10.
- the flip-flop 26 is therefore no longer immobilized; it tends to reposition itself in the unlocking position under the action of the spring 36.
- the lifting of the guardrail 10 by one or more of the passengers entails, if necessary, placing in abutment the railing element 17 against the first functional surface 30, which contributes to the rotation of the flip-flop 26 to the unlocking position.
- the railing member 17 is no longer trapped in the housing 34, the guardrail 10 can be moved to the raised position to allow passengers to get off the seat 1.
- the operation of the seat 1 according to the embodiment of the Figures 4 and 5 is similar to that described with reference to Figures 2 and 3 , with the difference that the rod 14 moves in rotation between the first position and the second position, and that the displacement of the locking member 32 can be stopped by the stops 58 so that the locking member 32 stops in blocking or unlocking position (depending on the stop 58 against which it comes to rest).
- torsion spring 36 instead of a torsion spring 36, it can be envisaged to use a spring working in traction or compression.
- the locking means in particular the electromagnet 12, the rocker 26, and the locking member 46 are here arranged under the seat 1, and attached for example to a flange 60 extending under the seat 1, but they could be attached to any other part of the seat 1, ie elsewhere than under seat 1.

Description
La présente invention concerne un siège de remontée mécanique et une installation de remontée mécanique équipée de ce siège.The present invention relates to a lift seat and a lift facility equipped with this seat.
Traditionnellement, une installation de remontée mécanique permet à des passagers, skieurs ou piétons, de remonter ou descendre des pentes. Une installation de remontée mécanique comporte généralement deux stations d'extrémité, une station placée en bas de pente et une station placée en haut de pente. Ces stations d'extrémité sont reliées par un câble aérien porteur et tracteur pouvant former une boucle fermée. Il est connu d'entraîner le câble grâce à des poulies et de le soutenir au moyen de pylônes. Des véhicules suspendus au câble permettent l'acheminement des passagers d'une station d'extrémité à une autre.Traditionally, a ski lift facility allows passengers, skiers or pedestrians to go up or down slopes. A ski lift facility usually has two end stations, a station at the bottom of the slope and a station at the top of the slope. These end stations are connected by a carrying aerial cable and tractor can form a closed loop. It is known to drive the cable through pulleys and support it with pylons. Vehicles suspended from the cable allow the transportation of passengers from one end station to another.
L'acheminement des passagers en haut ou en bas d'une pente nécessite de respecter un haut niveau de sécurité, car les sièges circulent généralement à une distance relativement importante du sol. Il est ainsi connu du document de brevet
Il est également connu d'améliorer la sécurité des passagers par l'utilisation d'un garde-corps limitant les risques de chute accidentelle d'un passager à partir du siège.It is also known to improve the safety of passengers by the use of a guard rail limiting the risk of accidental fall of a passenger from the seat.
Les garde-corps sont classiquement montés de manière pivotante par rapport au siège pour permettre l'embarquement et le débarquement des passagers. On distingue une position d'utilisation abaissée et une position d'utilisation relevée du garde-corps. Lorsque le garde-corps est en position abaissée, celui-ci constitue un obstacle au basculement d'un passager dans le vide. Cette position abaissée du garde-corps est normalement adoptée pendant une phase de trajet du siège hors des zones d'embarquement et de débarquement. Lorsque le garde-corps est dans une position relevée, celui-ci libère l'espace à l'avant du siège de manière à permettre aux passagers de s'installer sur le siège ou le quitter. Le garde-corps est donc normalement en position relevée lorsque le siège se situe dans une zone d'embarquement ou de débarquement.The railings are conventionally pivotally mounted relative to the seat to allow the loading and unloading of passengers. There is a lowered use position and a raised use position of the guardrail. When the railing is in the lowered position, it is an obstacle to the tilting of a passenger in a vacuum. This lowered position of the guardrail is normally adopted during a phase of travel of the seat out of the loading and unloading areas. When the railing is in a raised position, it releases the space at the front of the seat so as to allow the passengers to settle in the seat or leave it. The guardrail is normally in the raised position when the seat is in a loading or unloading area.
Pour des raisons de sécurité, le garde-corps ne doit pas être relevé pendant toute la phase de trajet hors des zones d'embarquement et de débarquement. Toutefois, les sièges existants n'offrent généralement qu'une sécurité limitée, dans la mesure où rien n'empêche les passagers de relever le garde-corps pendant le trajet du siège hors des zones d'embarquement et de débarquement.For safety reasons, the guardrail must not be lifted during the entire journey phase out of the loading and unloading areas. However, existing seats are generally only of limited safety, as nothing prevents passengers from guardrail during the journey from the seat outside the loading and unloading areas.
Pour y remédier, il est connu d'utiliser des dispositifs de blocage mécanique du garde-corps, comme celui divulgué dans le document de brevet
Aussi la présente invention a-t-elle pour but de résoudre tout ou partie des inconvénients mentionnés ci-dessus en proposant un siège de remontée mécanique offrant une sécurité accrue pour les passagers en empêchant le soulèvement du garde-corps pendant les phases de transit du siège entre deux stations d'extrémité, tout en étant adaptable aux installations de remontée mécanique existantes, léger, et de maintenance aisée.Thus, the present invention aims to solve all or some of the disadvantages mentioned above by providing a mechanical lift seat providing increased safety for passengers by preventing the lifting of the railing during the transit phases of the seat between two end stations, while being adaptable to existing lifts, lightweight, and easy maintenance.
A cet effet, la présente invention a pour objet un siège de remontée mécanique comprenant un garde-corps apte à occuper une première position extrême abaissée délimitant un espace clos permettant de prévenir la chute d'un passager et une seconde position extrême relevée dans laquelle le garde-corps libère un espace à l'avant du siège pour permettre le débarquement d'un ou plusieurs passager(s), et des moyens de verrouillage du garde-corps lorsque celui-ci occupe une position abaissée, caractérisé en ce que les moyens de verrouillage comprennent un électroaimant bistable muni d'une tige mobile entre une première position stable dans laquelle la tige permet le verrouillage du garde-corps en position abaissée par interposition d'un obstacle sur la trajectoire ascendante décrite par un élément de garde-corps pour passer de la position abaissée à la position relevée, et une deuxième position stable dans laquelle la tige permet le déverrouillage du garde-corps en vue de son déplacement jusqu'à la position relevée par déplacement de l'obstacle à distance de la trajectoire ascendante décrite par l'élément de garde-corps.For this purpose, the subject of the present invention is a mechanical lift seat comprising a railing capable of occupying a first extreme lowered position delimiting an enclosed space making it possible to prevent the fall of a passenger and a second raised extreme position in which the guardrail releases a space at the front of the seat to allow the disembarkation of one or more passenger (s), and means of locking the guardrail when it occupies a lowered position, characterized in that the means locking means comprise a bistable electromagnet provided with a rod movable between a first stable position in which the rod allows the railing to be locked in the lowered position by interposing an obstacle on the upward path described by a railing element for move from the lowered position to the raised position, and a second stable position in which the rod allows the unlocking of the railing e n view of its movement to the raised position by moving the obstacle away from the upward path described by the guardrail element.
Ainsi, le siège selon l'invention offre la possibilité de verrouiller le garde-corps en position abaissée, ce qui contribue à accroître la sécurité de passagers, avec un système de complexité moindre que les systèmes préexistants, nécessitant en outre peu de maintenance, et capable d'être aisément installé sur des sièges préexistants sans toutefois les alourdir de manière excessive.Thus, the seat according to the invention offers the possibility of locking the guardrail in the lowered position, which contributes to increased passenger safety, with a system of lesser complexity than the existing systems, requiring little maintenance, and able to be easily installed on pre-existing seats without weighing them excessively.
De plus, l'utilisation d'un électroaimant bistable à tige mobile rend le siège moins sensible aux conditions climatiques auxquelles il est exposé, souvent hostiles dans la mesure où les sièges sont utilisés en montagne, et très souvent en période hivernale. En particulier, le système de verrouillage de garde-corps du siège selon l'invention présente une sensibilité moindre au givre qui tend à se former sur les éléments métalliques des sièges, et qui peut perturber le fonctionnement de systèmes de verrouillage de garde-corps traditionnels.In addition, the use of a bistable electromagnet movable rod makes the seat less sensitive to climatic conditions to which it is exposed, often hostile to the extent that the seats are used in the mountains, and very often in winter. In particular, the guardrail locking system of the seat according to the invention has a lower sensitivity to frost which tends to form on the metal elements of the seats, and which can disrupt the operation of traditional guardrail locking systems .
Selon un mode de réalisation, l'obstacle est formé par une bascule mobile en rotation par rapport au siège entre une position de verrouillage dans laquelle une première surface fonctionnelle d'une première extrémité de la bascule est agencée en travers de la trajectoire ascendante décrite par l'élément de garde-corps, et une position de déverrouillage dans laquelle la première surface fonctionnelle est agencée à distance de la trajectoire ascendante décrite par l'élément de garde-corps, le déplacement de la tige de l'électroaimant bistable de la deuxième position stable jusqu'à la première position stable permettant d'immobiliser la bascule dans la position de verrouillage et, de façon réciproque, le déplacement de la tige depuis la première position stable vers la deuxième position stable permettant d'autoriser la rotation de la bascule jusqu'à la position de déverrouillage.According to one embodiment, the obstacle is formed by a rocker movable in rotation with respect to the seat between a locking position in which a first functional surface of a first end of the rocker is arranged across the upward trajectory described by the railing element, and an unlocking position in which the first functional surface is arranged at a distance from the upward path described by the railing element, the displacement of the rod of the bistable electromagnet of the second stable position until the first stable position to immobilize the rocker in the locking position and, reciprocally, the movement of the rod from the first stable position to the second stable position to allow the rotation of the rocker to the unlock position.
Avantageusement, les moyens de verrouillage comprennent également un organe de blocage mobile par rapport au siège et rattaché à la tige de l'électroaimant, le déplacement de la tige provoquant conséquemment un déplacement de l'organe de blocage entre une position de blocage de la bascule, dans laquelle l'organe de blocage est apte à bloquer la bascule en position de verrouillage, et une position de déblocage, dans laquelle l'organe de blocage autorise la rotation de la bascule de la position de verrouillage vers la position de déverrouillage.Advantageously, the locking means also comprise a movable locking member relative to the seat and attached to the rod of the electromagnet, the displacement of the rod consequently causing a displacement of the locking member between a blocking position of the rocker , wherein the locking member is adapted to lock the latch in the locking position, and an unlocking position, wherein the locking member allows the rotation of the latch from the locking position to the unlocking position.
L'organe de blocage est par exemple mobile en rotation.The locking member is for example rotatable.
L'organe de blocage peut comprendre une extrémité destinée à venir sur la trajectoire d'un organe de butée d'une deuxième extrémité de la bascule.The locking member may comprise an end intended to come in the path of an abutment member of a second end of the rocker.
L'organe de blocage est par exemple sensiblement rectiligne, et l'axe de rotation de l'organe de blocage peut être agencé sensiblement sur une tangente au cercle décrit par l'organe de butée de la deuxième extrémité lorsque la bascule pivote par rapport au siège.The locking member is for example substantially rectilinear, and the axis of rotation of the locking member can be arranged substantially on a tangent to the circle described by the stop member of the second end when the rocker pivots relative to the seat.
La tangente peut correspondre à la tangente en un point M de l'organe de butée lorsque la bascule est en position de verrouillage.The tangent may correspond to the tangent at a point M of the stop member when the rocker is in the locking position.
De manière avantageuse, la première extrémité de la bascule comprend une deuxième surface fonctionnelle agencée sur la trajectoire décrite par l'élément de garde-corps lorsque le garde-corps est déplacé de la position relevée vers la position abaissée pour provoquer, lorsque l'élément de garde-corps vient en appui contre la deuxième surface fonctionnelle, la rotation de la bascule depuis la position de déverrouillage jusqu'à la position de verrouillage.Advantageously, the first end of the rocker comprises a second functional surface arranged on the path described by the railing element when the railing is moved from the raised position to the lowered position to cause, when the element guardrail bears against the second functional surface, the rotation of the rocker from the unlocking position to the locking position.
La deuxième surface fonctionnelle peut être agencée en regard de la première surface fonctionnelle de sorte que la première surface fonctionnelle et la deuxième surface fonctionnelle délimitent entre elles un logement pour la réception de l'élément de garde-corps.The second functional surface may be arranged facing the first functional surface so that the first functional surface and the second functional surface delimit between them a housing for receiving the guardrail element.
Selon, une possibilité, le siège comprend des moyens de rappel en position agencés pour rappeler la bascule dans la position de déverrouillage.According to one possibility, the seat comprises return means in position arranged to return the latch in the unlocking position.
Les moyens de rappel peuvent comprendre un ressort de torsion.The return means may comprise a torsion spring.
Le ressort de torsion comprend par exemple une première extrémité en appui contre un ergot rattaché au siège et une deuxième extrémité rattachée à la bascule.The torsion spring comprises for example a first end bearing against a lug attached to the seat and a second end attached to the rocker.
La deuxième extrémité peut être insérée dans un logement ménagé sur la bascule.The second end can be inserted into a housing provided on the rocker.
Selon une forme d'exécution, le siège comprend des conducteurs électriques embarqués agencés pour être connectés à un circuit électrique d'alimentation équipant une installation de remontée mécanique, les conducteurs électriques embarqués étant électriquement reliés à l'électroaimant bistable.According to one embodiment, the seat includes onboard electrical conductors arranged to be connected to an electrical supply circuit fitted to a mechanical lift installation, the embedded electrical conductors being electrically connected to the bistable electromagnet.
Selon un mode de réalisation, la tige de l'électroaimant est mobile en translation entre la première position stable et la deuxième position stable.According to one embodiment, the rod of the electromagnet is movable in translation between the first stable position and the second stable position.
Selon une variante, la tige de l'électroaimant est mobile en rotation entre la première position stable et la deuxième position stable.According to a variant, the rod of the electromagnet is rotatable between the first stable position and the second stable position.
De manière avantageuse, l'électroaimant est pourvu de deux butées agencées pour stopper la rotation de l'organe de blocage lorsque l'organe de blocage déplacé par la tige parvient dans la position de blocage et dans la position de déblocage.Advantageously, the electromagnet is provided with two stops arranged to stop the rotation of the locking member when the locking member moved by the rod reaches the locking position and the unlocking position.
Les moyens de verrouillage peuvent être agencés sous le siège. Par exemple, le siège comprend un flasque s'étendant sous le siège et supportant l'électroaimant et/ou l'organe de blocage et/ou la bascule.The locking means can be arranged under the seat. For example, the seat comprises a flange extending under the seat and supporting the electromagnet and / or the locking member and / or the rocker.
L'élément de garde-corps peut correspondre à un ergot solidaire d'un marchepied du garde-corps.The guardrail element may correspond to a lug integral with a step of the guardrail.
La tige de l'électroaimant est mobile alternativement entre la première position stable et la deuxième position stable par exemple sous l'action d'impulsions électriques à polarité alternée pouvant être déclenchées lors du passage du siège à l'entrée d'une zone de débarquement d'une station d'extrémité et/ou d'une zone d'embarquement d'une station d'extrémité.The rod of the electromagnet is movable alternately between the first stable position and the second stable position for example under the action of alternating polarity electrical pulses that can be triggered during the passage of the seat at the entrance of a landing area an end station and / or an embarkation area of an end station.
Selon une forme d'exécution, l'électroaimant comprend une première bobine et une deuxième bobine destinées à être alimentées alternativement pour déplacer de façon alternée la tige entre la première position et la deuxième position.According to one embodiment, the electromagnet comprises a first coil and a second coil intended to be fed alternately to alternately move the rod between the first position and the second position.
L'invention concerne également une installation de remontée mécanique comprenant au moins un siège de remontée mécanique ayant les caractéristiques précitées.The invention also relates to a mechanical lift installation comprising at least one mechanical lift seat having the aforementioned characteristics.

Comme cela est visible sur la
Le siège 1 de remontée mécanique comprend un garde-corps 10 apte à occuper une première position extrême abaissée, visible en traits pleins sur la
Le siège 1 de remontée mécanique comprend également des moyens de verrouillage du garde-corps 10 lorsque celui-ci occupe une position abaissée.The
Selon l'invention, les moyens de verrouillage comprennent un électroaimant 12 bistable, muni d'une tige 14, visibles sur les
La tige 14 est mobile entre une première position stable, représentée sur les
Selon le mode de réalisation illustré aux
Selon le mode de réalisation illustré aux
Quelque soit le mouvement de la tige 14 (translation ou rotation), celle-ci est mobile alternativement entre la première position stable et la deuxième position stable.Whatever the movement of the rod 14 (translation or rotation), it is movable alternately between the first stable position and the second stable position.
L'électroaimant 12 comprend par exemple une première bobine 16 et une deuxième bobine 18, chacune connectée électriquement, par exemple via une liaison filaire 20, à deux conducteurs électriques 22, 24 embarqués sur le siège 1, notamment sur la suspente 2, comme ceux décrits dans le document de brevet
Si on donne une impulsion électrique à la première bobine 16, il s'en suivra par exemple le déplacement de la tige 14 de la deuxième position jusqu'à la première position (« sortie » de la tige 14 pour une tige 14 mobile en translation, et « rotation à droite » pour une tige 14 mobile en rotation). Tant que l'on ne donne pas une impulsion électrique à la deuxième bobine 18, cet état demeure. Il n'est pas nécessaire de maintenir la première bobine 16 alimentée en électricité pour que la tige 14 reste en première position. Lorsqu'une impulsion électrique est appliquée à la deuxième bobine 18, l'état de l'électroaimant 12 bistable change : la tige 14 se déplace de la première position jusqu'à la deuxième position (elle « rentre » pour un électroaimant 12 à tige 14 mobile en translation, elle pivote à gauche, par rapport au point de vue des
Ainsi, lorsque l'on donne une impulsion électrique à l'électroaimant 12 bistable, on change l'état de cet électroaimant 12 bistable, c'est-à-dire la position de la tige 14, selon que l'on alimente la première bobine 16 ou la deuxième bobine 18.Thus, when an electric impulse is given to the
Le verrouillage du garde-corps 10 est réalisé par interposition d'un obstacle sur la trajectoire ascendante décrite par un élément 17 de garde-corps, comme un ergot solidaire d'un marchepied du garde-corps 10, pour passer de la position abaissée à la position relevée, tandis que le déverrouillage du garde-corps 10 est réalisé par déplacement de cet obstacle à distance de la trajectoire ascendante décrite par l'élément 17 de garde-corps.The
L'obstacle est ici formé par une bascule 26, mobile en rotation par rapport au siège 1 autour d'une liaison pivot P1, entre une position de verrouillage, illustrée aux
La bascule 26 comprend notamment une première extrémité 28, munie d'une première surface fonctionnelle 30. En position de verrouillage, la première surface fonctionnelle 30 est agencée en travers de la trajectoire ascendante décrite par l'élément 16 de garde-corps, comme cela est visible sur la
La première extrémité 28 de la bascule 26 peut aussi comprendre une deuxième surface fonctionnelle 32 agencée sur la trajectoire descendante décrite par l'élément 16 de garde-corps lorsque le garde-corps 10 est déplacé de la position relevée vers la position abaissée.The
Ainsi, lorsque le garde-corps 10 est déplacé jusqu'à la position abaissée, l'élément 16 de garde-corps vient en appui contre la deuxième surface fonctionnelle 32, ce qui provoque la rotation de la bascule 26 depuis la position de déverrouillage jusqu'à la position de verrouillage.Thus, when the
La deuxième surface fonctionnelle 32 est par exemple agencée en regard de la première surface fonctionnelle 30 de sorte que la première surface fonctionnelle 30 et la deuxième surface fonctionnelle 32 délimitent entre elles un logement 34 pour la réception de l'élément 16 de garde-corps.The second
Des moyens de rappel en position, comme un ressort 36 de torsion, peuvent être prévus pour rappeler la bascule 26 dans la position de déverrouillage. Le ressort 36 de torsion comprend par exemple une première extrémité 38 en appui contre un ergot 40 solidaire du siège 1 et une deuxième extrémité 42 rattachée à la bascule 26. La deuxième extrémité 42 peut être insérée dans un logement 44 ménagé sur la bascule 26. Ainsi, la bascule 26 présente une position d'équilibre stable correspondant à la position de déverrouillage.In-position return means, such as a
On notera que le déplacement de la tige 14 depuis la deuxième position jusqu'à la première position permet d'immobiliser la bascule 26 dans la position de verrouillage, tandis que le déplacement inverse de la tige 14, c'est-à-dire son déplacement de la première position vers la deuxième position, permet d'autoriser la rotation de la bascule 26 jusqu'à ce que cette dernière atteigne la position de déverrouillage.It will be noted that the displacement of the
Pour ce faire, le siège 1 peut comprendre un organe 46 de blocage. L'organe 46 de blocage est mobile par rapport au siège 1, par exemple en rotation autour d'une liaison pivot P2, entre une position de blocage, visible sur les
L'organe 46 de blocage est ici rattaché à la tige 14 de l'électroaimant 12, de sorte que le déplacement de la tige 14 provoque le déplacement simultané de l'organe 46 de blocage.The locking
De plus, lorsque la tige 14 est en première position, l'organe 46 de blocage est en position de blocage, tandis que lorsque la tige 14 est en deuxième position, l'organe 46 de blocage est en position de déblocage.In addition, when the
Ainsi, le déplacement de la tige 14 de la première position vers la deuxième position provoque celui de l'organe 46 de blocage de la position de blocage vers la position de déblocage, et inversement.Thus, the displacement of the
Comme cela est visible sur les
Avantageusement, l'organe 46 de blocage peut être sensiblement rectiligne, et son axe de rotation par rapport au siège 1 peut être agencé sur ou dans le voisinage d'une tangente 54 en un point M au cercle 56 décrit par l'organe de butée 50 lorsque la bascule 26 pivote par rapport au siège 1, le point M correspondant à un point de cette organe de butée 50 lorsque la bascule 26 est en position de verrouillage.Advantageously, the locking
On remarquera que, selon le mode de réalisation illustré aux
Le fonctionnement du siège 1 selon le mode de réalisation des
Dans cette situation, le système de verrouillage du garde-corps 10 est désarmé ; le garde-corps 10 peut être librement déplacé entre la position relevée et la position abaissée.In this situation, the
Lorsque le siège 1 parvient à l'entrée d'une zone d'embarquement 106, l'électroaimant 12 est alimenté en électricité via les conducteurs électriques 22, 24, de sorte que la tige 14 soit déplacée jusqu'à la première position stable, ce qui entraîne le déplacement de l'organe 46 de blocage jusqu'à la position de blocage. Plus précisément, une impulsion électrique est appliquée aux pôles électriques de la première bobine 16. Dans cette situation, le système de verrouillage du garde-corps 10 est armé.When the
Lorsque le ou les passagers abaissent le garde-corps 10 jusqu'à la position abaissée, par exemple en sortie de la zone d'embarquement 106, l'élément 17 de garde-corps vient en appui contre la deuxième surface fonctionnelle 32, et entraîne la bascule 26 dans un mouvement de rotation vers la position de verrouillage de la bascule 26.When the passenger or passengers lower the
Au cours de ce mouvement de rotation, la deuxième extrémité 52 de la bascule 26 appuie contre l'organe 46 de blocage en le repoussant légèrement avant de se positionner juste au-dessus de l'extrémité 48 de l'organe 46 de blocage, ce dernier étant repoussé par la tige 14 maintenue en tendant à se maintenir dans la première position stable. L'organe 46 de blocage agit donc à la manière d'un cliquet anti-retour. Simultanément, la première surface fonctionnelle 30 se positionne derrière l'élément 17 de garde-corps, qu'elle emprisonne dans le logement 34, en entravant la trajectoire retour de l'élément 17 de garde-corps.During this rotational movement, the
La bascule 26 est alors immobilisée en position de blocage. Le garde-corps 10 est quant à lui verrouillé dans la position abaissée.The
Lorsque le siège 1 parvient dans une zone de débarquement 108, l'électroaimant 12 est alimenté électriquement via les conducteurs électriques 22, 24, ce qui provoque le déplacement de la tige 14 de la première position jusqu'à la deuxième position stable, et conséquemment celui de l'organe 46 de blocage jusqu'à la position de déblocage. Plus précisément, lorsque le siège 1 parvient dans une zone de débarquement 108, la deuxième bobine 18 est alimentée en électricité pour déplacer la tige 14 en deuxième position et désarmer ainsi le verrouillage du garde-corps 10.When the
La bascule 26 n'est donc plus immobilisée ; elle tend à se repositionner en position de déverrouillage sous l'action du ressort 36. En outre, le soulèvement du garde-corps 10 par un ou plusieurs des passagers entraîne le cas échéant la mise en appui de l'élément 17 de garde-corps contre la première surface fonctionnelle 30, ce qui contribue à la rotation de la bascule 26 jusqu'à la position de déverrouillage.The flip-
L'élément 17 de garde-corps n'étant plus prisonnier du logement 34, le garde-corps 10 peut être déplacé jusqu'à la position relevée pour permettre aux passagers de descendre du siège 1.The
Lorsque le siège 1 parvient ensuite à l'entrée d'une zone d'embarquement 106, un nouveau cycle peut commencer, l'alimentation de l'électroaimant 12 avec une polarité de nouveau inversée permettant de réarmer le système de verrouillage du garde-corps 10.When the
Le fonctionnement du siège 1 selon le mode de réalisation des
Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit ci-dessus, ce mode de réalisation n'ayant été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par la substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described above, this embodiment having been given as an example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by the substitution of technical equivalents, without departing from the scope of protection of the invention.
Ainsi, au lieu d'un ressort 36 de torsion, il peut être envisagé d'utiliser un ressort travaillant en traction ou compression.Thus, instead of a
On notera que les moyens de verrouillage, notamment l'électroaimant 12, la bascule 26, et l'organe 46 de blocage sont ici agencés sous le siège 1, et rattachés par exemple à un flasque 60 s'étendant sous le siège 1, mais ils pourraient être rattachés à toute autre partie du siège 1, autrement dit ailleurs que sous le siège 1.Note that the locking means, in particular the
