Patent ID: 7311340

Claim:
A lock for an opening leaf of a motor vehicle comprising: operating means for opening from the outside of the motor vehicle and operating means for opening from the inside of the motor vehicle, a primary lever which is mounted so that it can pivot about a fixed primary pin, between an angular unlocking position and an angular locking position, in order to inhibit the means for operating from the outside, a secondary lever which is mounted so that it can pivot about a fixed secondary pin, substantially parallel to the primary pin, between an angular unlocking position and an angular locking position, in order to inhibit the means for operating from the inside, a driving member which is connected to the primary lever in order to directly pivot the primary lever, from its locking position toward its unlocking position, during an operating phase referred to an outside unlocking phase, wherein a connection means is arranged between the primary lever and the secondary lever so as to link the angular displacement of the two levers during outside unlocking phase, with the aim of bringing about global unlocking of the lock by pivoting the two levers from their respective locking positions toward their respective unlocking positions; wherein the connection means is a link rod which comprises a point of articulation on the primary lever and a point of articulation on the secondary lever whereby the position of the articulation points of the link rod is selected so that, during the global unlocking phase, the secondary lever reaches its unlocking position before the primary lever reaches its unlocking position.
