Description

CLOSING SYSTEM WITH LOCKING DEVICE

  CENTRALIZED AND REMOTE CONTROL FOR A MOTOR VEHICLE

  The invention relates to a locking system with central locking and remote control for a motor vehicle, said motor vehicle comprising at least one side door of a motor vehicle with door reinforcements, a rear compartment with tailgate, a chassis of a motor vehicle and, in the bodywork, on both sides, the front uprights, the central uprights

  and rear pillars, the side door of the vehicle

  tomobile being fixed to a front upright by at least one upper hinge, the closure system arranged in the side door of the motor vehicle and against the

  tailgate with vehicle door closure

  motor vehicle equipped with a positioning device, consisting of a motor and a mechanism, and associated with a strike, an internal actuation device and an external actuation means. The term "chassis

  motor vehicle "also includes the assembly of plan-

  dear usual. The term "tailgate" also includes a rear door. The rear compartment can be designed as a luggage compartment. The term "closure system" designates by system an ordered set, in other words a plurality of elements which are spatially ordered and cooperate by their functions and which are thus in a relationship of interdependence. In such a closing system, at least two motor vehicle door closings are provided, one in the motor vehicle door at least one, the other against the tailgate, these closings in number

  at least two belonging to the central locking.

  In the closing system known in the art in many embodiments, the door closing of the motor vehicle is housed in the door of the motor vehicle. The keeper, previously also called "closing cleat" and, in the embodiment in the form of an axis, "closing pin", is located in the central upright. The interior actuating device is located in the door of the motor vehicle and acts, by means of a chain of levers, on the door closing of a motor vehicle located in the door of the motor vehicle. The external actuation means

  comprises, on the one hand, a mechanical actuation device

  a pic which also acts through a chain

  levers, on the door closing of the motor vehicle

  bile from the outside door handle. For central locking, on the other hand, on modern motor vehicles, an electric remote control external actuation device is provided. In emergency mode, when the electrical device

  external actuator and / or the remote control are

  failing, there is an acting lock cylinder

  mechanically on the door closing of the vehicle

  mobile. It is located in the door of the motor vehicle, most often in the area of the exterior handle of

  the door. The components and components of the closure system

  ture described are known in various embodiments.

  The known measures set out above have given satisfaction, but can be improved. The invention aims to improve a closure system having the

  structure described above, namely by reducing consi-

  the probability of failure of the

  central locking and therefore telecom-

  order. According to the invention, this object is achieved by a closing system with central locking device for a motor vehicle, said motor vehicle comprising at least one side door of a motor vehicle with door reinforcements, a rear compartment with tailgate, a motor vehicle chassis and, in the bodywork, on both sides, front uprights, central uprights and rear uprights, the side door of the motor vehicle being fixed to a front upright by at least one upper hinge, the closure system arranged in the side door of the motor vehicle and against the tailgate comprising a motor vehicle door closure provided with a positioning device, consisting of an electric motor and a mechanism, and associated with a strike, with a device for internal actuation and an external actuation means, and the following characteristics being combined ies: 1.1) the door closure of the motor vehicle is housed in the central upright associated with the side door of the motor vehicle, 1.2) the keeper is located in the side door of the motor vehicle and protrudes from the

  front face thereof having an inter-

  action with the door closing of the motor vehicle, 1.3) the interior actuation device is a mechanical actuation device with Bowden cable for interior actuation and Bowden cable actuation lever, 1.4) the exterior actuation means comprises ,

  on the one hand, an actuation device ex-

  mechanical interior with external Bowden cable for actuation and Bowden cable actuation lever and, on the other hand, an external electrical actuation device with remote control, the internal Bowden cable for actuation being disposed in or on a frame element of the motor vehicle and the lever for actuating the internal Bowden cable being disposed inside the passenger compartment, the Bowden cable for external actuation being

  housed in or on an element of the chassis of the motor vehicle

  bile, and the lever for actuating the external Bowden cable for actuation being housed in the rear compartment which can be closed by the tailgate, and only the closure of the tailgate being equipped, for the mode

  emergency, a lock cylinder actuated by a key.

  It is understood that the closing of a vehicle door

  mobile itself can be protected against theft for the unlocked and locked positions and that it can have a first notch and Ad1 main craun, this

  which does not require a detailed explanation.

  The invention starts from the fact that, in the known closure system with centralized locking device and remote control, a plurality of electric cables lead to the various door closings of the motor vehicle which are part of the centralized locking, namely at least for supplying energy the device

  positioning and to transmit information to it.

  Insofar as they must follow the movements of the door of the motor vehicle and the tailgate, these cables are subjected to alternating bending stresses with a considerable bending angle. This requires installations of an appropriate level of security and therefore expensive. Despite everything, there remains a reduced but real probability that the cable will break and compromise the functioning of the central locking device and therefore the remote control. If this risk does not present a danger since an emergency mechanical actuation is possible, it is however troublesome. The invention is based on the observation that, in the event of the motor vehicle door closing being mounted in the central upright, the electric cables are arranged so as to no longer be subjected to any bending stress during the opening and closing of the door of the motor vehicle or the tailgate. The probability that a cable breaks is thus considerably reduced, which also makes it possible to simplify the installations put

in action.

  In detail, there are several variants of design and embodiment of this closure system in the context of the invention. According to an embodiment characterized by a high security on the mechanical level, associated with a simple structure, the door reinforcement is designed in the form of a carrier V-frame, the branches of the V of which are connected to the upper and lower hinges and whose base of the V is solidar-isee the

  mess. The door reinforcement can thus be designed to

  have optimal characteristics in terms of

  resistance to deformation and mechanical stress.

  It may result that the strike plate and the associated door closing of the motor vehicle are not

  not, in the central upright, at the height which is habi-

  so much theirs today, without autanrt.oser An problem since the actuation lever of the cAblke Sowden

  of internal actuation is independent of this implantation

  tation and can be placed at a convenient and ergonomic point

  mique. In the locking system according to the invention, the remote control consists of a receiver arranged on the motor vehicle, of a corresponding mobile transmitter, which can also be called "electronic key of the vehicle", and of a sensor. switching mounted on the central upright or on another part of the body. The switching sensor is therefore no longer in the door of the motor vehicle. Conditions

  are particularly simple if closing

  door structure of the motor vehicle comprises, for

  electrical actuation, an electrical device for

  location with electric motor, position element-

  spring and spring tensioned by a rotational movement

  tion, the spring can be tensioned when

  the positioning element is extended or retracted by the mo-

  electric tor, and the positioning element capable

  be recalled by the spring after stopping the electric motor

  stick. Corresponding positioning devices are known (cf. DE-U-86 21 592.2), but are implemented in a particular way within the framework of the invention, namely in the case of a door closing.

  motor vehicle located in a central upright.

  These conditions allow simple switching to be carried out.

  The invention will be explained in detail below in detail.

  reference to drawings simply representing an exemplary embodiment. These drawings show in: - Figure 1, the diagram of a motor vehicle seen from the side and equipped with a closure system according to the invention, - Figure 2, the object of Figure 1 seen from the exterior, - Figure 3, on a significantly enlarged scale

  compared to FIG. 1, the door closing of the vehicle

  automobile of Figure 1, with the door closed, and

closed position.

  The diagram shown in Figure 1 corresponds to

  a motor vehicle 1 comprising at least one door la-

  motor vehicle body 2 with door reinforcement 3, a rear compartment 4 with tailgate 5, and a chassis 6 of a motor vehicle. The chassis 6 of a motor vehicle can be part of a non-floor assembly

  shown who also carries the chassis. In the coach-

  series 7 are arranged, on both sides, front uprights 8, central uprights 9 and rear uprights 10. It is understood that the motor vehicle 1 comprises, as usual, window panes, window guides

  and actuators for window panes.

  In the area of the side door 2 of a motor vehicle

  and in the tailgate area 5, this closing system

  ture has a self-closing vehicle door 11

  mobile, fitted with a positioning device 12 consisting of

  killed by an engine 13 and a mechanism 14, a strike 15, a

  internal actuating device 16, 17 and a device

  tif external actuation 18, 19, 20.

  By comparing Figures 1 and 2, we see that

  the closing 11 of a motor vehicle door is im-

  planted in the central upright 9 associated with the side door

  Lane 2 of the motor vehicle. The keeper 15 is located in the side door 2 of the motor vehicle and projects from the front face of the latter while interacting with the door closure 11 of the motor vehicle. The interior actuation device is a mechanical actuation device with a Bowden cable 16 for interior actuation and a corresponding lever 17 for actuation of Bowden cable. The external actuation means comprises, on the one hand, a mechanical external actuation device with a Bowden cable 18 for external actuation and a corresponding lever 19 for actuation of Bowden cable. However, the device

  on the other hand, there is a provision

  sitif 20 of external electrical actuation with telecom-

  order. On this point, we will also refer to Figure 3.

  Bowden 16 interior actuation cable runs

  in or against an element 21 of the chassis 6 of the vehicle au-

  tomobile. The lever 17 for actuating this Bowden cable 16 for interior actuation is located inside the passenger compartment, for example in the dashboard or on a front pillar 8. The Bowden cable 18 for exterior actuation also passes into or against an element 21 of the chassis 6 of the motor vehicle and terminates in the rear compartment 4. At this location is the lever 19 for actuating the Bowden cable 18 for external actuation. The rear compartment 4 is closed by the

  tailgate 5. Only the closing 11 of the vehicle door

  automobile cule corresponding to the tailgate 5 is equi-

  key of a lock cylinder 22 actuated by a computer key

  and is only intended for the so-called

relief.

  It can be seen in FIGS. 1 and 2 that the door reinforcement 3 is designed in the form of a load-bearing framework

  in V, whose branches 23 of V are connected to the char-

  upper 24 and lower 25 and whose base 26

  of the V is secured to the keeper 15. In contrast, the clos-

  Motor vehicle door ture 11 is located in the

center pillar 9.

  The remote control consists of a receiver 27,

  installed in the motor vehicle 1, of a mo-

  corresponding bile 28 forming electronic key which is

  suggested in Figure 2, and also a sensor for com-

  mutation 29. In the embodiment, the

  switching 29 is arranged on the central upright 9.

  The transmitter 28 can be in the hand of a driver

  who wants to open door 2 of the motor vehicle.

  It can be seen in FIG. 3 that the door closure 11 of the motor vehicle comprises, for the electrical actuation of an electrical positioning device 12, an electric motor 13, a positioning element 30 and a spring 31 which can be tensioned by a rotational movement. The spring 31 is tensioned when the positioning element 30 is taken out or returned by the electric motor 13 in operation. This arrangement is provided so that the positioning element 30 is returned by the spring 31 after the electric motor 13 has stopped, the spring 31 then being released again. For more than

  details, see document DE-U-86 21 592.2.
