Definitions

• the present invention relates to a control device for a vehicle door locking system. It is particularly intended for motor vehicle doors to control the locking and unlocking modes of door handles.
• the locks implemented in this area must meet the desired features, increasingly sophisticated, while assuming the technical constraints related to reliability, cost or congestion.
• vehicles today have a child safety function, a function that controls the ability to open one of the rear doors when the inside handle is operated. Another function more and more encountered is said to double lock and is to prohibit any door opening by the handles, inside and outside. It will be understood that providing a vehicle with these various locking control functions involves complex means, the organs necessary for each locking function multiplying the numbers of total parts.
• WO-A1-2009030046 discloses an attempt to rationalize a locking system by proposing to use a single motor to operate two locking functions. This goal is however not really achieved since it continues to involve another actuator such as a key or a motor used for another locking function.
• the object of the invention is to overcome all or part of the disadvantages of the techniques known hitherto. It proposes for this purpose a control device for a vehicle door locking system comprising:
• the device is such that the second control element comprises a selective coupling member, said coupling member having additional mobility between a first coupling position in which it kinematically connects the second control element and a control member. support of the drive means and a second coupling position in which it kinematically connects the second control element and the first control element and in which it authorizes the driving of the first control element by the support member.
• it advantageously comprises means for returning the coupling member in the second coupling position when the second control element is in the second control position and return means in the first coupling position when the second element command is in the first command position.
• the two control elements have coupled mobilities that allow in particular to drive them through a single engine.
• the number of parts necessary for the operation of the mechanism is very limited, inducing a single motor and a single power transmission kinematic chain to the two control elements.
• the additional mobility of the coupling member is a rotation.
• the member can thus easily move from one position to another by tilting.
• Return means employing at least one spring can easily be implemented in this embodiment.
• the return means of the coupling member comprise a torsion spring configured to exert a return force towards the second coupling position when the first control element is in the second control position and a biasing force in the opposite direction to the first coupling position when the first control element is in the first control position.
• This variant uses a single spring to make two return efforts in opposite directions. This is made possible by taking advantage of the translational movement of the coupling member in the mobility of the second coupling element. This displacement modifies the relative position of the anchoring points of the spring and that of the axis of rotation of the coupling member so that the direction of rotation that tends to exert the force of the spring on the coupling member is reversed.
• the mobility of the second control element between the first control position and the second control position is a translation.
• the mobility of the first control element between first control position and the second control position can be alternatively or alternatively a translation, the translation paths of the first control element and the second control element being preferably parallel.
• the invention may further optionally include at least any of the following:
• the coupling member comprises an application surface of a first bearing surface of the support member adapted to push the second control element from its first control position to its second control position; coupling member being in its first coupling position;
• the force exerted by the support member on the application surface is configured to oppose the force of the return means
• the support member comprises a second bearing surface adapted to push the first control element from its first control position to its second control position when the coupling member is in its second coupling position and that the first control element is in its second control position;
• the support member comprises a third bearing surface adapted to push the first control element from its second control position to its first control position, said first control element driving the second control element from its second position control to its first control position, when the coupling member is in its second position;
• the second control element comprises a guide zone around which the coupling member is rotatably mounted
• the second control element comprises a pad around which the coupling member is rotatably mounted

• the invention also relates to a vehicle having at least one locking system.
• the locking system comprises combined locking means able to act simultaneously on an inner handle and on an outer handle and dedicated locking means able to act solely on the inner handle, the first command element controlling the combined locking means and the second control element controlling the dedicated locking means.
• the system comprises dedicated locking means, the first control element acting on the locking of an outer handle, the second control element acting on the locking of an inner handle, which can be combined sequentially to act simultaneously on both locks
• the control positions are preferably the following: the first control position of the first control element is an unlocked position,

• the second control position of the first control element is a locked position
• the second control position of the second control element is a locked position.
