Definitions
- the invention relates to an opening lock of a motor vehicle.
- the opening of the driver and / or the passenger is equipped with a function of prevention of locking the key, usually on the front side opening.
- Such a lock generally comprises a function commonly called “override” which consists in unlocking the opening when an inner opening handle is actuated.
- override consists in unlocking the opening when an inner opening handle is actuated.
- Some of these locks are sometimes also equipped with a lock emergency function, which is operated by a mechanical interface of the key, which can be used only when the door is open, for the purpose of securing the vehicle when a failure of the electrical circuit.
- This function thus makes it possible to lock the open opening without electric power.
- Such an opening, locked open will remain locked during and after the slamming of the opening.
- the key is in hand and is not trapped. It is the same if the opening in question is accessible to a conviction by key, the door being closed. This is the classic case of the driver's door for example.
- the lock is made turnkey.
- the on-board computer will generally prohibit the locking operation of the open door or all doors, to eliminate the risk of getting out of the vehicle by forgetting the key before closing opening.
- This function is an "open door condemnation ban” made electrically.
- the lock can be actuated, when the opening is opened, a second function of comfort is provided which allows a closing slammed door remains locked after the breakdown.
- This second function is commonly called "Key-Less-Lock". It is used to lock the vehicle without introduction or activation of the key. It is generally installed on the front opening and operates, when the outer handle is maintained actuated, when closing by slamming of the opening.
- the "Cancel" function is carried out by means of a rotary transfer lever which transforms the closing movement of a part commonly called a false pawl integral with the ratchet of the lock into an unlocking movement of a central locking lever.
- the false pawl comprises a flange pushing an arm of the transfer lever, which rotates clockwise, and a tenon of this transfer lever moves in a slot of the central locking lever, so that this last turns counterclockwise, from a lock state to an unlocked state.
- the "Key-Less-Lock” function is achieved by disengaging the transfer lever, when the outer opening lever connected to the outer handle holds the central locking lever in its locking position.
- the flange of the pawl then leads the arm of the transfer lever which rotates clockwise, the tenon of this lever then sliding freely in the slot of the central locking lever.
- the transfer lever thus works as a motion inverter and requires an additional axis of rotation and interface elements with the central locking lever and the false pawl, namely the flange and the tenon. It must be made of steel in order to withstand and transmit the energy of the opening of the opening when it closes.
- the object of the invention is to provide a motor vehicle door lock comprising a function mechanism "Cancel" simpler, lighter and less expensive, without the need for a transfer lever and therefore having fewer parts.
- a motor vehicle door lock comprising a latch cooperating with a pawl, a central locking lever, an external opening lever connected to an external handle, an internal locking lever connected to a latch.
- internal locking control as well as central locking lever, a false pawl being integral with said pawl, lock providing a function of "Cancel" by means of a transmission arrangement of a closing movement of said pawl in a displacement of unlocking said central locking lever and characterized in that said arrangement comprises an element integrated in said central locking lever and disposed on the path of said false pawl upon closing of the opening, said central locking lever moving from the position locked to the unlocked position by sliding in one direction only.
- the function "Cancel" is achieved by a direct transmission cooperation of the central locking lever and the false pawl, in the sense that any inversion of displacements, amplification of displacements and any multi-contacts are suppressed.
- said transmission arrangement is a spring.
- said spring is a torsion spring and said element a free end and bent of this spring.
- said torsion spring has a central axis perpendicular to said direction of sliding of said central locking lever.
- said central locking lever comprises a finger of cooperation with a flange of said external opening lever, the actuation of this external opening lever bringing said flange against said finger and locking said central locking lever in the locked position.
- said transmission arrangement is a tenon integral with said central locking lever.
- said tenon is perpendicular to said direction of sliding of said central locking lever.
- said false pawl is integral with the pawl by a common axis of rotation.
- Said direction of sliding of said central locking lever is advantageously perpendicular to said common axis of rotation of said pawl and said false pawl.
- the lock comprises a bistable spring whose stable rest positions correspond to the locking and unlocking positions, said bistable spring being advantageously connected to said internal locking lever.
- Figures 1 to 6 are partial perspective views of a lock according to a first embodiment according to the invention, when operating in "Cancel” mode.
- Figures 7 to 12 are partial perspective views of a lock according to this first embodiment according to the invention, when operating in "Key-Less-Lock” mode.
- Figure 13 is a partial perspective view of a lock according to a second embodiment according to the invention.
- the motor vehicle door lock in accordance with the invention conventionally comprises a bolt 5 cooperating with a pawl 6, a central locking lever 1 and an external opening lever 4 connected to an inner handle connected to a control device. interlocking as well as audition central locking lever, a false pawl 3 being secured to the pawl 6.
- the intermediate opening lever 7 is in known manner connected to the central locking lever 1 in locking movement where it is disengaged from the outer opening lever 4.
- This lock provides a function of "Cancel” by means of a transmission arrangement of a closing movement of the false pawl 3 in an unlocking movement of the central locking lever 1.
- this arrangement comprises an element integrated in the central locking lever 1 and disposed in the path of the false pawl 3 when closing the sash, the central locking lever 1 moving from the locked position to the position unlocked by sliding in one direction only.
- the false pawl 3 is secured to the pawl 6 by a common axis of rotation 3A. Said direction of sliding of the central locking lever 1 is perpendicular to the common axis of rotation of the pawl 6 and the false pawl 3.
- the first embodiment is firstly described in detail according to FIGS. 1 to 12, according to "Cancel” and "Key-Less-Lock” function.
- the torsion spring 2 has a central axis perpendicular to the sliding direction of the central locking lever 1.
- the released intermediate release lever 7 then returns to the unlocked position and the lock is in the unlocked state.
- a bistable spring 8 only shown in FIGS. 1 and 2 in its two stability positions corresponding to the unlocked and locked position of the lock causes it in end position and state the lock remains unlocked.
- This bistable spring 8, of the type for example flush horn, is preferably connected to the inner locking lever 9 which is bi-directionally connected to the central locking lever 1 and thus also ensures the bistability.
- the opening being thus locked and open, the handle is actuated and maintained actuated until the closure of the opening.
- the outer opening lever 4 is rotated in the clockwise direction as shown in FIG. 8 and opposes its flange 4A facing a finger 1A carried by a corresponding tenon of the central locking lever 1, as also shown. in Figure 9.
- the bolt 5 then continues its rotation until its complete displacement illustrated in FIG. 12, without modification of the locked state and by another cycle of tire then release of the spring 2.
- This arrangement according to the invention makes the kinematics of European type locks easily compatible with the functions of the type of Asian locks, and at a lower cost of components.
- the creation of an "Override” function can be summed up as ensuring a direct interior opening, without worry of synchronization of unlocking movement, the proposed "Cancel” function, by the addition of a simple small spring, ensuring unlocking during the first opening movement as well as closing the lock.
- the "Key-Less-Lock” function rendered simply by adding the 4A interface to the external opening lever, makes it possible to provide a "back-up" function without the addition of a component or key interface access.
- Figure 13 shows a second embodiment of the invention.
- the previous spring 2 integrated in the central locking lever 1 is replaced by a pin 2 'integral with the central locking lever 1, for example made by molding on the latter, and perpendicular to the sliding direction of the locking lever central 1.
