Definitions
- the present invention relates to a door handle assembly for a vehicle and to a method for unlocking this door handle assembly.
- Some luxury vehicles are equipped with a recessed handle in their door. These handles make it possible to obtain an improved aesthetic effect because they merge with the rest of the door. They are very discreet.
- Known sash handle assemblies conventionally comprise a base intended to be fixed to the door and a handle connected to the base by a hinge.
- the joint can be horizontal or vertical, which is more common.
- the handle is rotatable relative to the base between a rest position in which it is positioned substantially parallel to the base and embedded in the door, and an opening position of the door in which it is inclined relative to the base and therefore deployed.
- the sash handle assemblies also include a handle actuating device housed in the base for bringing it to the open position.
- the actuating device comprises a motor driving the handle via gears to bring it towards the open position.
- the user can pull on the handle to bring it into an over-open position in which the handle is more inclined with respect to the base, allowing a mechanical unlocking system to be unlocked to open the door .
- Conventional unlocking systems are housed in the door and are connected to the sash handle assembly by a cable. Actuation of the handle exerts a pull on the cable which in turn activates the unlocking of the unlocking system.
- the user can then pull the door open.
- the document US8701353 describes another solution in which the unlocking system is electronic. Pressing a capacitive sensor provided on the handle unlocks the unlocking system.
- capacitive sensors are not always reliable. They do not always detect the presence of a user's fingers, especially if they are covered by a textile material such as gloves. The unlocking system therefore cannot be unlocked and the user cannot open the door.
- the invention aims to solve all or part of these drawbacks by proposing a door handle assembly for a vehicle and a method for unlocking this door handle assembly making it possible to make the opening of the door more reliable.
- the first control device and the second control device are each connected to the electrical unlocking system by a respective electrical connection.
- the first control device and/or the second control device may comprise a separate switch connected to their respective electrical connection.
- the switch comprises a movable element between a rest position and an activated position obtained when the user presses on the tactile zone of the handle or moves the handle into the over-open position.
- a control signal is transmitted from the switch to the electric unlocking system.
- the touch zone is movable so that pressing the touch zone causes the movable element to move into the activated position.
- the first control device and/or the second control device may comprise a deformable membrane forming the touch zone.
- control device and/or the second control device comprise a cap which can move in translation and on which the tactile zone is formed.
- the displacement of the cap against the movable element causes the displacement of the latter and the generation of the control signal.
- the control device and/or the second control device comprise a return means exerting a force on the cap to bring it back to the initial position.
- the invention also relates to a method for unlocking a door handle assembly as defined above and comprising a step of positioning the handle in the open position by the actuating device.
- the invention thus provides a door handle assembly for a vehicle and a method for unlocking this door handle assembly making it possible to make the opening of the door more reliable.
- the electric unlocking system can be unlocked even when the handle sensor fails.
- the elements of the sash handle assembly are light and are therefore difficult to move under the acceleration created during an accident.
- This sash handle assembly also makes it possible to simplify assembly or maintenance because the assembly of the lock can be carried out from the outside and after the assembly of the handle. It is not necessary to remove the interior door trim panel to disassemble the handle when the vehicle is finished.
- the use of a wired link unlike a wireless link simplifies the electronics and avoids having a power source in the handle.
- the handle is also lightened.
- the figure 1 represents a door handle assembly 1 intended to be mounted on a door of a motor vehicle when the handle 2 is in the rest position.
- This opening handle assembly 1 comprises a base 3 intended to be fixed to the door of the vehicle and a handle 2 connected to the base 3 by a hinge (not shown) at a first end 4 of the handle 2.
- the articulation is preferably vertical.
- the base 3 is intended to be fixed on the internal wall of the door.
- the handle 2 is rotatable relative to the base 3 between a rest position in which it is positioned substantially parallel to the base 3 and a door opening position in which it is inclined relative to the base 3.
- the rest position also corresponds to the closed position of the handle 2 in which the handle is retracted towards the door.
- the open position it corresponds to the position in which the handle 2 is deployed to be grasped by the user when he wants to pull on the door to open it.
- the sash handle assembly 1 comprises an actuating device 5 of the handle ( fig. 3 ) housed in the base 3 and which is intended to provide movement to the handle 2 to at least bring it into the open position.
- the actuating device 5 comprises a motor cooperating with gears to provide a motorized movement to the handle 2 to bring it at least into the open position.
- the motor can also make it possible to close or retract the handle 2 towards the base 3 (or the door 2).
- the actuating device 5 can be actuated mechanically to obtain a deployed position, such as a system provided with a spring mechanism as described in the application WO2017077077 .
- the sash handle assembly 1 comprises a first control device 6a for opening the door.
- the first control device 6a is connected to an electrical unlocking system (not shown) by an electrical connection 7a (wired connection), also called first electrical connection 7a.
- the first control device 6a is intended to be activated by the hand of a user and to generate a control signal which is intended to be transmitted to the electric unlocking system to unlock it in order to allow the door to be opened by the 'user.
- the electrical connection 7a comprises an electrical cable 15 having a first end 16 connected to the first control device 6a and a second end 17 comprising a connector 18 intended to be connected to the electrical unlocking system.
- the first control device 6a is integrated in the handle 2.
- the first control device 6a is housed in a cavity 19 provided in the handle 2.
- the electrical connection 7a starts from the first control device 6a, passes through a part of the handle 2 and emerges from the latter through an opening 20, as shown in the picture 3 .
- Electrical connection 7a then passes through base 3 to emerge via a first face 21 of base 3.
- the handle 2 includes a tactile zone 8 on its internal surface 11 intended to receive pressure to activate the first control device 6a.
- the handle 2 has a parallelepipedal shape.
- its internal surface 11 is positioned opposite base 3 and more precisely opposite a second face 22 of base 3.
- the tactile zone 8 of the handle 2 is positioned against or is very close to this second face 22.
- the advantage is that the touch zone 8 is protected from the outside. It is also hidden to improve the aesthetic effect.
- the first control device 6a comprises a switch 9, as shown in the figures 4 to 7 , which is connected to the electrical connection 7a.
- the switch 9 comprises a movable element 10 between a rest position and an activated position obtained when the user presses on the tactile zone 8 of the handle 2.
- the movable element 10 is for example a push button which returns to its initial position by means of a spring.
- a control signal is then transmitted from switch 9 to the electric unlocking system so that it unlocks and leaves the door free of any movement so that it can be opened by a user.
- the touch zone 8 can be movable so that pressing the touch zone 8 causes the movable element 10 to move into the activated position.
- the figure 4 shows an example in which the first control device 6a comprises a deformable membrane 12 forming the touch zone 8.
- the deformable membrane 12 is made of polymer.
- the user exerts pressure on the deformable membrane 12 in a direction F.
- the deformable membrane 12 deforms to push the movable element 10 and activate the switch 9, that is to say switch it to the “ON” position.
- Switch 9 can be connected to an open electrical circuit which closes when switch 9 is pressed.
- the deformable membrane 12 has a generally U-shaped section defining a cavity 27 and covers the movable element 10 which is positioned in the cavity 27.
- the switch 9 may comprise a rigid plate 23 positioned against an internal surface 25 of the cavity 27 of the deformable membrane 12.
- the switch 9 is positioned on a support 26 in the shape of a "U" comprising two ends 29.
- the deformable membrane 12 comprises two ends 30 resting on the two respective ends 29 of the support 26.
- the deformable membrane 12 deforms when the user exerts pressure on it and returns to its initial position when the pressure is stopped.
- the two ends 30 of the deformable membrane 12 are retained between the two ends 29 of the support 26 and a peripheral wall 31 of the handle 2.
- the figure 5 illustrates another example in which the first control device 6a comprises a cap 13 movable in translation on which the tactile zone 8 is formed.
- the cap 13 is rigid and has a "U" shape defining a cavity 32.
- the cap 13 is positioned opposite the movable element 10.
- the cap 13 comprises a front wall 38, forming the touch zone 8, connected perpendicularly to two side walls 36 defining a cavity 32.
- the cap 13 advantageously comprises a lug 33 on its front wall 38 positioned opposite the movable element 10 to reduce its stroke.
- the movement of the cap 13 against the movable element 10 in the direction F causes the movement of the latter and the generation of the control signal.
- the switch 9 is positioned on a support 34 in the shape of a "U" comprising two flanges 35.
- the two side walls 36 of the switch 9 are each extended by a flange 40 perpendicular to the side walls 36.
- Each flange 40 is extended by a lateral lug 37 abutting against the support 34 when the user exerts pressure on the movable element 10 in the direction F.
- the lateral lug 37 is substantially perpendicular to the flanges 40.
- the first control device 6a comprises a return means 14 exerting a return force on the cap 13 to bring it back to the initial position.
- Each side lug 37 is surrounded by a spring 14, forming the return means 14.
- the figure 6 illustrates another example in which the first control device 6a also comprises a deformable membrane 12 forming the touch zone 8.
- the peripheral wall 31 of the handle 2 is covered by the deformable membrane 12.
- the deformable membrane 12 has a smaller thickness at the location of the tactile zone 8 so as to form a curved internal zone 41.
- the first control device 6a comprises a support 42 on which the switch 9 is mounted.
- the support 42 comprises two side edges 43 forming support zones 44 for the deformable membrane 12.
- the mobile element 10 is in permanent contact with the curved internal zone 41.
- the travel and the deformation of the deformable membrane 12 is minimal, a few micrometers for example.
- the figure 7 illustrates another example in which the first control device 6a comprises a touch sensor which can be a capacitive sensor 45 integrated in the handle 2. It can be integrated by overmoulding for example.
- the touch sensor can alternatively be a piezoelectric sensor integrated in the handle 2.
- the activation of the first control device 6a is carried out by pressure on a tactile zone 8 provided on the internal surface 11 of the handle 2, the handle 2 remaining stationary in its open position during this activation.
- the sash handle assembly 1 comprises a second control device 6b positioned on the base 3, as shown in the picture 3 .
- the second control device 6b is actuated by a movement of the handle 2 from the open position to an over-open position to generate a second control signal.
- the over-open position corresponds to a position in which the handle 2 is more inclined relative to the base 3 and relative to the open position.

- the switch 9 comprises a movable element 10 between a rest position and an activated position obtained when the user brings the handle 2 into the over-open position.
- a second control signal is then transmitted from switch 9 to the electric unlocking system.
- the rotational movement of the handle 2 towards the over-open position causes the first end 4 of the handle 2 to press on the movable element 10 of the switch 9 to switch it and transmit the second control signal to the unlocking system electric.
- the electrical connection 7b comprises an electrical cable 15 having a first end 16 connected to the second control device 6b and a second end 17 comprising a connector 18 intended to be connected to the electrical unlocking system.
- the sash handle assembly 1 comprises two control devices 6a, 6b, the first control device 6a of which is positioned in the handle 2 and the second control device 6b positioned on the base 3.
- the second control device 6b takes over so that the unlocking of the electric unlocking system is ensured.
- the first control device 6a comprises a capacitive sensor which does not detect the user's fingers each time.
- the capacitive sensor of the first control device 6a malfunctions, the user pulls on the handle 2 to bring it into the over-open position, then triggering the second control device 6b.
- the electrical unlocking system thus receives either the first control signal or the second control signal in order to unlock it and allow the door to be opened by the user.
- the handle 2 may include a spring bringing it back from the over-open position to the rest position.
- a counterweight can be provided in the handle 2 or the base 3 to optimize the inertial balance with the spring of the handle 2.

Description
La présente invention concerne un ensemble de poignée d'ouvrant pour véhicule et un procédé de déverrouillage de cet ensemble de poignée d'ouvrant.The present invention relates to a door handle assembly for a vehicle and to a method for unlocking this door handle assembly.
Certains véhicules de luxe sont équipés d'une poignée encastrée dans leur porte. Ces poignées permettent d'obtenir un effet esthétique amélioré car se confondent avec le reste de la porte. Elles sont très discrètes.Some luxury vehicles are equipped with a recessed handle in their door. These handles make it possible to obtain an improved aesthetic effect because they merge with the rest of the door. They are very discreet.
Ces ensembles de poignée encastrée existent sous des versions mécaniques et des versions motorisées.These recessed handle sets are available in mechanical and motorized versions.
Les ensembles de poignée d'ouvrant connus comprennent classiquement une base destinée à être fixée sur la porte et une poignée reliée à la base par une articulation. L'articulation peux être horizontale ou verticale, ce qui est plus fréquent.Known sash handle assemblies conventionally comprise a base intended to be fixed to the door and a handle connected to the base by a hinge. The joint can be horizontal or vertical, which is more common.
La poignée est mobile en rotation par rapport à la base entre une position de repos dans laquelle elle est positionnée sensiblement parallèlement à la base et encastrée dans la porte, et une position d'ouverture de la porte dans laquelle elle est inclinée par rapport à la base et donc déployée.The handle is rotatable relative to the base between a rest position in which it is positioned substantially parallel to the base and embedded in the door, and an opening position of the door in which it is inclined relative to the base and therefore deployed.
Les ensembles de poignée d'ouvrant comprennent également un dispositif d'actionnement de la poignée logé dans la base permettant de l'amenervers la position d'ouverture.The sash handle assemblies also include a handle actuating device housed in the base for bringing it to the open position.
Dans le cas d'un ensemble de poignée d'ouvrant électrique tel que décrit dans le document
A partir de cette position, l'utilisateur peut tirer sur la poignée pour l'amener dans une position de sur-ouverture dans laquelle la poignée est davantage inclinée par rapport à la base, permettant de déverrouiller un système de déverrouillage mécanique pour ouvrir la porte.From this position, the user can pull on the handle to bring it into an over-open position in which the handle is more inclined with respect to the base, allowing a mechanical unlocking system to be unlocked to open the door .
Les systèmes de déverrouillage classique sont logés dans la porte et sont reliée à l'ensemble de poignée d'ouvrant par un câble. L'actionnement de la poignée exerce une traction sur le câble qui actionne à son tour le déblocage du système de déverrouillage.Conventional unlocking systems are housed in the door and are connected to the sash handle assembly by a cable. Actuation of the handle exerts a pull on the cable which in turn activates the unlocking of the unlocking system.
L'utilisateur peut ensuite tirer sur la porte pour l'ouvrir.The user can then pull the door open.
Cependant, il arrive que ce type de système de déverrouillage mécanique se déverrouille tout seul en cas d'accidents à cause du déplacement par inertie de ses composants qui présentent un poid non nul.However, it happens that this type of mechanical unlocking system unlocks by itself in the event of an accident due to the movement by inertia of its components which have a non-zero weight.
Le document
Ceci permet d'éviter un déverrouillage accidentel et donc une ouverture non souhaitée de la porte pendant un accident.This prevents accidental unlocking and therefore unwanted opening of the door during an accident.
Cependant, les détecteurs capacitifs ne sont pas toujours fiables. Ils ne détectent pas toujours la présence des doigts d'un utilisateur, surtout s'ils sont recouverts par une matière textile tels des gants. Le système de déverrouillage ne peut donc pas être déverrouillé et l'utilisateur ne peut pas ouvrir la porte.However, capacitive sensors are not always reliable. They do not always detect the presence of a user's fingers, especially if they are covered by a textile material such as gloves. The unlocking system therefore cannot be unlocked and the user cannot open the door.
L'invention vise à résoudre tout ou partie de ces inconvénients en proposant un ensemble de poignée d'ouvrant pour véhicule et un procédé de déverrouillage de cet ensemble de poignée d'ouvrant permettant de fiabiliser l'ouverture de la porte.The invention aims to solve all or part of these drawbacks by proposing a door handle assembly for a vehicle and a method for unlocking this door handle assembly making it possible to make the opening of the door more reliable.
L'invention concerne un ensemble de poignée d'ouvrant destiné à être monté sur une porte d'un véhicule automobile. L'ensemble de poignée d'ouvrant comprend:
- une base destinée à être fixée sur la porte,
- une poignée reliée à la base par une articulation à une première extrémité de la poignée, la poignée étant mobile en rotation par rapport à la base entre une position de repos dans laquelle elle est positionnée sensiblement parallèlement à la base, et une position d'ouverture de la porte dans laquelle elle est inclinée par rapport à la base, et
- un dispositif d'actionnement de la poignée logé dans la base, destiné à fournir un mouvement à la poignée pour au moins l'amener en position d'ouverture.
- a base intended to be fixed on the door,
- a handle connected to the base by a hinge at a first end of the handle, the handle being rotatable relative to the base between a rest position in which it is positioned substantially parallel to the base, and an open position of the door in which it is angled with respect to the base, and
- a handle actuating device housed in the base, intended to provide movement to the handle to bring it at least into the open position.
Selon l'invention, l'ensemble de poignée d'ouvrant comprend:
- un premier dispositif de commande de l'ouverture de la porte intégré dans la poignée et relié à un système de déverrouillage électrique, la poignée comprenant une zone tactile sur une surface interne destinée à recevoir une pression par la main d'un utilisateur pour activer le premier dispositif de commande et générer un premier signal de commande,
- un deuxième dispositif de commande positionné sur la base, le deuxième dispositif de commande étant actionné par un déplacement de la poignée de la position d'ouverture vers une position de sur-ouverture pour générer un deuxième signal de commande, le système de déverrouillage électrique recevant le premier signal de commande ou le deuxième signal de commande afin de se déverrouiller et permettre l'ouverture de la porte par l'utilisateur.
- a first door opening control device integrated in the handle and connected to an electric unlocking system, the handle comprising a touch zone on an internal surface intended to receive pressure from a user's hand to activate the first control device and generate a first control signal,
- a second control device positioned on the base, the second control device being actuated by movement of the handle from the open position to an over-open position to generate a second control signal, the electric unlocking system receiving the first control signal or the second control signal in order to unlock and allow the opening of the door by the user.
De préférence, le premier dispositif de commande et le deuxième dispositif de commande sont chacun reliés au système de déverrouillage électrique par une liaison électrique respective.Preferably, the first control device and the second control device are each connected to the electrical unlocking system by a respective electrical connection.
Le premier dispositif de commande et/ou le deuxième dispositif de commande peuvent comprendre un commutateur distinct connecté à leur liaison électrique respective. Le commutateur comprend un élément mobile entre une position repos et une position activée obtenue lorsque l'utilisateur appuie sur la zone tactile de la poignée ou déplace la poignée en position de sur-ouverture. Un signal de commande est transmis du commutateur vers le système de déverrouillage électrique.The first control device and/or the second control device may comprise a separate switch connected to their respective electrical connection. The switch comprises a movable element between a rest position and an activated position obtained when the user presses on the tactile zone of the handle or moves the handle into the over-open position. A control signal is transmitted from the switch to the electric unlocking system.
De préférence, la zone tactile est mobile de façon à ce qu'une pression sur la zone tactile entraine un déplacement de l'élément mobile en position activée.Preferably, the touch zone is movable so that pressing the touch zone causes the movable element to move into the activated position.
Le premier dispositif de commande et/ou le deuxième dispositif de commande peuvent comprendre une membrane déformable formant la zone tactile.The first control device and/or the second control device may comprise a deformable membrane forming the touch zone.
Avantageusement, le dispositif de commande et/ou le deuxième dispositif de commande comprennent un capuchon mobile en translation et sur lequel est formé la zone tactile. Le déplacement du capuchon contre l'élément mobile entraine le déplacement de ce dernier et la génération du signal de commande. Le dispositif de commande et/ou le deuxième dispositif de commande comprennent un moyen de rappel exerçant une force sur le capuchon pour le ramener en position initiale.Advantageously, the control device and/or the second control device comprise a cap which can move in translation and on which the tactile zone is formed. The displacement of the cap against the movable element causes the displacement of the latter and the generation of the control signal. The control device and/or the second control device comprise a return means exerting a force on the cap to bring it back to the initial position.
L'invention concerne également un procédé de déverrouillage d'un ensemble de poignée d'ouvrant tel que défini précédemment et comprenant une étape de positionnement de la poignée en position d'ouverture par le dispositif d'actionnement.The invention also relates to a method for unlocking a door handle assembly as defined above and comprising a step of positioning the handle in the open position by the actuating device.
Selon l'invention, le procédé comprend les étapes suivantes:
- activation d'un premier dispositif de commande réalisée par une pression de la main d'un utilisateur sur une zone tactile prévue sur une surface interne de la poignée pour activer le premier dispositif de commande et générer un premier signal de commande,
- si le premier signal de commande n'est pas transmis au système de déverrouillage électrique, activation d'un deuxième dispositif de commande positionné sur la base par un déplacement de la poignée de la position d'ouverture vers une position de sur-ouverture pour générer un deuxième signal de commande, et
- transmission du deuxième signal de commande vers un système de déverrouillage électrique pour le déverrouiller afin d'autoriser l'ouverture de la porte par l'utilisateur.
- activation of a first control device carried out by pressing a user's hand on a tactile zone provided on an internal surface of the handle to activate the first control device and generate a first control signal,
- if the first control signal is not transmitted to the electric unlocking system, activating a second control device positioned on the base by moving the handle from the open position to an over-open position to generate a second control signal, and
- transmission of the second control signal to an electric unlocking system to unlock it in order to authorize the opening of the door by the user.
L'invention fournit ainsi un ensemble de poignée d'ouvrant pour véhicule et un procédé de déverrouillage de cet ensemble de poignée d'ouvrant permettant de fiabiliser l'ouverture de la porte.The invention thus provides a door handle assembly for a vehicle and a method for unlocking this door handle assembly making it possible to make the opening of the door more reliable.
Le système de déverrouillage électrique peut être déverrouillé même lorsque le détecteur de la poignée est défaillant.The electric unlocking system can be unlocked even when the handle sensor fails.
De plus, les éléments de l'ensemble de poignée d'ouvrant sont légers et sont donc difficilement déplaçables sous l'accélération créée lors d'un accident.In addition, the elements of the sash handle assembly are light and are therefore difficult to move under the acceleration created during an accident.
Cet ensemble de poignée d'ouvrant permet également de simplifier le montage ou la maintenance car l'assemblage du verrou peut être réalisé de l'extérieur et après le montage de la poignée. Il n'est pas nécessaire d'enlever le panneau d'habillage intérieur de la porte pour démonter la poignée lorsque le véhicule est fini.This sash handle assembly also makes it possible to simplify assembly or maintenance because the assembly of the lock can be carried out from the outside and after the assembly of the handle. It is not necessary to remove the interior door trim panel to disassemble the handle when the vehicle is finished.
Il est également possible d'intégrer une antenne ou un système d'éclairage dans la base.It is also possible to integrate an antenna or a lighting system in the base.
L'utilisation d'une liaison filaire contrairement à une liaison sans fil permet de simplifier l'électronique et d'éviter d'avoir une source d'alimentation dans la poignée. La poignée est également allégée.The use of a wired link unlike a wireless link simplifies the electronics and avoids having a power source in the handle. The handle is also lightened.

L'ensemble de poignée d'ouvrant 1 comprend un deuxième dispositif de commande 6b positionné sur la base 3, comme représenté sur la
Le deuxième dispositif de commande 6b est actionné par un déplacement de la poignée 2 de la position d'ouverture vers une position de sur-ouverture pour générer un deuxième signal de commande.The
La position de sur-ouverture correspond à une position dans laquelle la poignée 2 est davantage inclinée par rapport à la base 3 et par rapport à la position d'ouverture.The over-open position corresponds to a position in which the
Autrement dit, l'angle formé entre la poignée 2 et la base 3 est plus grand dans la position de sur-ouverture que dans la position d'ouverture.In other words, the angle formed between the
Le deuxième dispositif de commande 6b est avantageusement positionné à proximité de la première extrémité 4 de la poignée 2.The
Le deuxième dispositif de commande 6b peut être identique au premier dispositif de commande 6a.The
De préférence, le deuxième dispositif de commande 6b comprend un commutateur 9 connecté à une autre liaison électrique 7b, dite deuxième liaison électrique 7b.Preferably, the
Le commutateur 9 comprend un élément mobile 10 entre une position repos et une position activée obtenue lorsque l'utilisateur amène la poignée 2 en position de sur-ouverture.The
Un deuxième signal de commande est alors transmis du commutateur 9 vers le système de déverrouillage électrique.A second control signal is then transmitted from
Lorsque la poignée 2 est dans sa position d'ouverture, l'utilisateur tire davantage dessus et vers lui pour l'amener en position de sur-ouverture.When the
Le mouvement de rotation de la poignée 2 vers la position de sur-ouverture entraine une pression de la première extrémité 4 de la poignée 2 sur l'élément mobile 10 du commutateur 9 pour le commuter et transmettre le deuxième signal de commande au système de déverrouillage électrique.The rotational movement of the
La liaison électrique 7b comprend un câble électrique 15 présentant une première extrémité 16 reliée au deuxième dispositif de commande 6b et une deuxième extrémité 17 comprenant un connecteur 18 destiné à être connecté au système de déverrouillage électrique.The
Ainsi, l'ensemble de poignée d'ouvrant 1 comprend deux dispositifs de commande 6a, 6b dont le premier dispositif de commande 6a positionné dans la poignée 2 et le deuxième dispositif de commande 6b positionné sur la base 3.Thus, the
Le procédé de déverrouillage de l'ensemble de poignée d'ouvrant 1 comprend les étapes suivantes:
- activation du premier dispositif de commande 6a réalisée par une pression de la main d'un utilisateur sur une zone tactile 8 prévue sur une
surface interne 11 de la poignée 2 pour activer le premier dispositif de commande 6a et générer le premier signal de commande, - si le premier signal de commande n'est pas transmis au système de déverrouillage électrique, activation du deuxième dispositif de commande 6b positionné sur la
base 3 par un déplacement de la poignée 2 de la position d'ouverture vers la position de sur-ouverture pour générer le deuxième signal de commande, et - transmission du deuxième signal de commande vers le système de déverrouillage électrique pour le déverrouiller afin d'autoriser l'ouverture de la porte par l'utilisateur.

first control device 6a performed by pressing a user's hand on atactile zone 8 provided on aninternal surface 11 of thehandle 2 to activate thefirst control device 6a and generate the first control signal, - if the first control signal is not transmitted to the electric unlocking system, activation of the
second control device 6b positioned on thebase 3 by moving thehandle 2 from the open position to the over-open position to generate the second control signal, and - transmission of the second control signal to the electric unlocking system to unlock it in order to authorize the opening of the door by the user.
Par conséquent, si le premier dispositif de commande 6a est défaillant, le deuxième dispositif de commande 6b prend le relai de façon à ce que le déverrouillage du système de déverrouillage électrique soit assuré.Consequently, if the
Ceci est particulièrement avantageux lorsque le premier dispositif de commande 6a comprend un capteur capacitif qui ne détecte pas à chaque fois les doigts de l'utilisateur.This is particularly advantageous when the
Si le capteur capacitif du premier dispositif de commande 6a disfonctionne, l'utilisateur tire sur la poignée 2 pour l'amener en position de sur-ouverture, déclenchant alors le deuxième dispositif de commande 6b.If the capacitive sensor of the
Le système de déverrouillage électrique reçoit ainsi soit le premier signal de commande ou le deuxième signal de commande afin de le déverrouiller et permettre l'ouverture de la porte par l'utilisateur.The electrical unlocking system thus receives either the first control signal or the second control signal in order to unlock it and allow the door to be opened by the user.
La poignée 2 peut comprendre un ressort la ramenant de la position de sur-ouverture vers la position de repos.The
Un contrepoids peut être prévu dans la poignée 2 ou la base 3 pour optimiser l'équilibrage inertiel avec le ressort de la poignée 2.A counterweight can be provided in the
