  • said part has an opening for its articulation on a pin carried by the link of maneuver, so that the interior opening lever and the lever of the external opening are articulated on the same pin of the rod maneuver.
  • Said part may include a fork between the branches of which is intended to engage a locking pin the aforementioned locking / unlocking means, to rotate said part between a locked and unlocked position.
  • Said part may also have a tab extending laterally by relative to the body of said part, said tab being able to cooperate with one of the aforementioned control means.
  • the interior opening lever and the lever opening are mounted in the housing symmetrically by relation to a plane of symmetry perpendicular to their plane of pose and passing through their common axis of articulation.
  • the means interior and exterior control can be arranged parallel in the housing and symmetrically with respect to said plane of symmetry.
  • the tabs of the opening lever inside and the external opening lever intersect at said level plane of symmetry, so that the interior control means is located on the side opposite the fork of the interior opening lever, with respect to said plane of symmetry.
  • the means of locking / unlocking has two locking wheels, each wheel having a radially locking lug eccentric and perpendicularly projecting from the plane of said wheel, said wheels being arranged so that the lug of a first wheel engages in the range of the external opening lever, and the second wheel locking tab engages in the fork of the interior opening lever, each wheel being capable of be rotated to tilt the associated lever towards a disengaged position, in which its tab no longer cooperates with the means corresponding command.

  • the operating rod has a lug which projects from the plane of the rod and crosses a oblong opening in the bottom of the case to cooperate with the pawl in the retention compartment, said link being substantially linearly movable under the action of the levers opening hours.
  • the operating rod comprises a stud which is sandwiched between the branches of a spring, to remind said rod in its inactive position, a boss being formed in the kinematics compartment to come between the branches of the spring, so that the movement of the rod only causes the displacement of one of the two branches of the spring.
  • each wheel of locking is secured to its axis of rotation, one end of which has a slot accessible outside the housing, for example at the door edge level, to allow emergency locking mechanical, in the event of an electrical engine failure.
  • the kinematics compartment of the case extends on one side of the retention compartment.
  • the lock of the invention comprises a plastic casing 1 of substantially parallelepiped shape, a metal counter plate 2 having a substantially U-shaped profile and a plastic casing 3 illustrated only in FIG. 3.
  • the metal counter plate 2 is mounted on the underside of the housing 1, to define the retention compartment of the lock, the two lateral wings 2 a and 2 b of the counter plate 2 extending in a recess 1 has formed on the longitudinal walls of the housing 1.

  • Each cable 24, 26 comprises at its end located in a projecting pin kinematic compartment 24, 26a carried by an elongate slider 24 b, 26 b.
  • the slide 24 b , 26 b is intended to hold the pin 24 a , 26 a projecting upwards, so that the latter can cooperate with, respectively, the tab 21 b of the interior opening lever 21 and the tab 20 b of the exterior opening lever 20.
  • the cables 24, 26 are intended to be connected to an interior door handle and an exterior door handle respectively (not shown).
  • the protruding pin 24 a or 26 a causes a linear displacement of the tab 21 b or 20 b of the associated opening lever, and consequently a pivoting of the operating rod 11 or a linear translation of the operating rod 111, to act on the pawl 9.
  • the lock shown in the drawings being with electric locking / unlocking control, it comprises in the kinematics compartment two electric motors 27, 28.
  • the motor shaft 28 has the electric motor 28 protruding towards bottom and is integral in rotation with a pinion 29, said pinion 29 meshing peripherally with a toothed wheel 30 integral in rotation with a rotation shaft 31 which is mounted in a bearing 32.

  • the lock In the position illustrated in FIGS. 2 and 7, the lock is in its closed state and unlocked from the inside and from the outside.
  • traction is generated on the exterior opening control cable 26, which drives by its pin 26 to the tab 20 b of the exterior opening lever 20.
  • the opening lever outer 20 moves linearly, being guided in translation by its fork 20 a which slides on the locking pin 44.
  • the linear movement of the outer opening lever 20 causes the movement of the hinge pin 13 of the operating rod 11 which rotates counterclockwise.
  • the arm 15 illustrated in FIG. 6 pivots counterclockwise and pushes back the pin 9 a from the pawl 9, to release the bolt 8.
  • the tab 21 b of the internal opening lever 21 thus departs from the pin 24 a of the internal opening control cable 24, without however move the latter so that the interior door handle remains stationary.
  • the slide 26 b of the external opening control cable 26 has the purpose of preventing a rotation of the pin 26 a around the axis of the cable 26, to prevent this pin 26 a from escaping any cooperation with the tab 20 b of the external opening lever.
  • the operation of the interior door handle has an effect similar to that of the exterior door handle.
  • the locking wheel 40 could also be mechanically driven by a lock cylinder, for a front door, or by a frieze zipper, for a rear door.
  • the motor 27 is activated by a on-board identifier that detects the remoteness of a identifier worn by a badge on the user, in the case of a system says "hands-free".
  • the user When the user also wishes to lock the lock vis-à-vis the interior, in the case of a super conviction, or when the user wishes to lock the lock only vis-à-vis from the inside, in the case of a child conviction for the doors rear, it activates the motor 28 to drive the opening lever interior towards its condemned position.
  • the contactor 35 will then indicate the locked position from inside the lock, for example at vehicle dashboard level.
