Lock for motor vehicle opening comprising means for inside and outside locking

Abstract

The lock (10) comprises outside and inside control means which can be inhibited by locking a primary lever (16) and a secondary lever (22) respectively. A driving part (30) connected to the primary lever causes its pivoting from its locking to unlocking positions. A connecting rod (34) arranged between the primary and secondary levers links their angular displacement during outside unlocking.

Description

technical field

[0001] The invention relates to a lock for opening a motor vehicle.

[0002] The invention relates more particularly to a lock for opening a motor vehicle, which lock comprises:

[0003] - external opening controls and internal opening controls;

[0004] - a first lever rotatably mounted around a first fixed shaft, the first lever being rotatable between a locked angular position and an unlocked angular position, in order to disable external control means;

[0005] - a second lever rotatably mounted around a second fixed axis substantially parallel to the first axis, the second lever being rotatable between an unlocked angular position and a locked angular position in order to disable the internal control means;

[0006] - a transmission mechanism connected to the first lever for directly rotating the first lever from its locked position to its unlocked position in an operating phase called external unlocking.

[0007] The invention more particularly relates...

[0053] Figure 1 schematically shows a lock 10, for example for fastening to a door (not shown) of a motor vehicle, and manufactured according to a first embodiment of the invention.

[0054] For example, the lock 10 includes a fixed frame (not shown) on which the main parts constituting the locking mechanism of the lock 10 are mounted.

[0055] The main parts of the locking mechanism are shown in Figure 1.

[0056] The lock 10 includes an exterior opening control device, such as one in the shape of an exterior handle 12 (palette), located in the exterior wall of the vehicle door.

[0057] The lock 10 includes an interior opening control device, such as an interior handle 14, located in the interior wall of the vehicle door.

[0058] The lock 10 includes means for disabling the exterior handle 12, preventing the lock 10 from being opened from the outside of the vehicle. This de...
