Vehicle door locking mechanism
A vehicle door locking mechanism includes a lock cylinder for locking or unlocking a vehicle door by rotating a control paddle linked to a door latch, a kinematic lever provided on an inner door handle frame and linked to the door latch to allow opening of the door from inside a passenger cabin by rotation of an inner door handle, and a stopper knob supported by the inner door handle frame and a displaceable stopper which can be manually actuated by the stopper knob between a first position allowing rotation of the control paddle and a second position in which the stopper blocks the rotation of the control paddle preventing therefore opening of the vehicle door.
1 . A vehicle door locking mechanism comprising:
a lock cylinder configured to lock or unlock a vehicle door by rotating a control paddle linked to a door latch;
a kinematic lever provided on an inner door handle frame and linked to the door latch to allow opening of the door from inside a passenger cabin by rotation of an inner door handle; and
a stopper knob supported by the inner door handle frame and a displaceable stopper which is configured to be manually actuated by the stopper knob between a first position allowing rotation of the control paddle and a second position in which the stopper blocks the rotation of the control paddle to prevent an unlocking of the latch from outside of the vehicle door and therefore an opening of the vehicle door even via an authorized key.
2 . The vehicle door locking mechanism according to claim 1 , wherein the inner door handle is mechanically linked to the stopper knob via a Bowden cable such that an opening action on the inner door handle places the stopper in the first position allowing rotation of the control paddle.
3 . The vehicle door locking mechanism according to claim 1 , wherein the door latch and the stopper are housed in a common housing.
4 . The vehicle door locking mechanism according to claim 3 , further comprising cooperating indexing elements disposed on the displaceable stopper on a first side and on the housing on a second side.
5 . The vehicle door locking mechanism according to claim 1 , wherein the door latch comprises a control lever for unlocking the latch, the control lever is linked to the control paddle of the lock cylinder and the stopper is in contact of the latch in said second position.
6 . The vehicle door locking mechanism according to claim 5 , wherein the control lever rotates according to a rotational axis, the stopper is configured to be displaced along a linear pathway which is substantially perpendicular to the rotational axis of the control lever.
7 . The vehicle door locking mechanism according to claim 5 , wherein the stopper comprises a blocking end which is configured to intercept the control lever of the latch in said second position.
8 . The vehicle door locking mechanism according to claim 5 , wherein the control lever comprises a distal end provided with a blocking extension extending towards the stopper, the blocking end of the stopper is configured to intercept a blocking extension formed on the control lever.
