Definitions

  • the present invention relates to a door lock for motor vehicle, in particular a lock for unlocking automatic opening, and more particularly a lock electric assistance with opening and / or assistance to the conviction.
  • the front door locks and sometimes back are usually equipped with a mechanism of automatic unlocking on opening, when the user operates the interior door handle. Indeed, if a user rolls in a condemned position, for example, so as not to risk being assaulted when it stops at the traffic lights, it is important that accident, he can easily get out of his vehicle without having to first unlock the door before you can open it.
  • Another advantage is that the user, by operating the handle inside door, causes in one maneuver, both the unlocking and opening, while it would be pretty unpleasant, for a user, to be forced to unlock the door before to be able to open it.
  • this function of automatic unlocking at the opening also known as the "override" is energy consumer because the energy needed for unlocking is in addition to the energy required for the opening of the lock.
  • This energy can be provided by a manual effort of the user for a fully mechanical lock, or by electric assistance mechanisms for opening and unlocking, for an electric lock.
  • DE-A-24 42 797 discloses a lock according to the preamble of claim 1.
  • the object of the invention is to propose a lock for automatic unlocking at the opening which reduces the energy to provide to perform such a function and whose arrangement of mechanisms is perfected.
  • the invention aims to object a lock for a motor vehicle door, as defined in claim 1.
  • the support portion of the automatic unlocking means to the opening blocks the stop of the locking lever, which prohibits the locking the lock in the open position of the door.
  • the cam follower pin of the first lever is able to cooperate with an open door switch at the end of the race of rotation of the bolt towards its open position, said contactor of open door intended to emit a signal corresponding to door opening information to a central processing unit, to activate, in a manner known per se, for example, a light light on the dashboard of the vehicle or a light from ceiling lamp in the cockpit.
  • the means of automatic unlocking to the opening brings the locking lever to the unlocked position, before the end of opening stroke of the bolt.
  • the mechanism of condemnation includes a reversible electric motor to drive the lever of condemnation between his doomed positions and unlocked during centralized conviction or unlocking ordered from outside or inside.
  • the lock of the invention is associated with a shock sensor for, during the detection of a shock, send a command signal to the electric motor of the mechanism of condemnation to drive the judgment lever to its position unlocked.
  • a shock sensor for, during the detection of a shock, send a command signal to the electric motor of the mechanism of condemnation to drive the judgment lever to its position unlocked.
  • the actuating means mentioned above comprises a mechanical means of connection, such as a cable or a rod, connecting the pawl to an internal control means, by example a door handle or inner pallet.
  • the actuating means has an external opening lever adapted to cooperate with the ratchet to bring it into the bolt release position, said lever external opening being adapted to be driven by an engine electrical assistance for opening assistance, in response to a signal from command issued by an external opening contactor, when external control means is operated by the user.
  • the lock may comprise a mechanical means of external connection of which an outer portion is intended to be connected by means of external control and of which another inner portion extends into the second sealed compartment of the lock, said external opening contactor being disposed in said second sealed compartment on the path of said inner portion of the means external link mechanism, so as to emit a signal of external opening control, when the connecting means mechanics is moved on a determined opening stroke when actuation of the external control means.
  • the lock of the invention comprises a lock housing B, for example, made of plastic and a metal counter-plate 1 substantially square and having an opening 2 for the passage of a keeper (not shown) which is fixed, in a manner known per se, to a vertical upright of the chassis of a motor vehicle.
  • a keeper (not shown) which is fixed, in a manner known per se, to a vertical upright of the chassis of a motor vehicle.
  • against the plate 1 has a substantially L profile with the longer wing 1a extending in the transverse direction of the vehicle, door closed position, and whose smallest cross 1b extends in the direction longitudinal of the vehicle.
  • the housing B has a substantially rectangular parallelepiped shape whose largest dimension extends substantially in the vertical direction of the door.
  • the housing B has a first compartment 3 called retention, because it contains a bolt fork 4 adapted to retain the striker and a pawl 5 to lock the bolt 4 in the retaining position of the striker.
