ABSTRACT:
Motor vehicle door lock comprising: a latch (1); a pawl (3) which can adopt an "escapement" position; an operating member which, on the one hand, can adopt either an active position in which it acts, during its actuating movement, on the pawl to place it in the "escapement" position, or an inhibited position in which it has no effect on the pawl and, on the other hand, may experience an actuating movement in response to actuation of the door handle; and an electric device (15-24) which responds at least to an unlock signal by moving the operating member from its inhibited position as far as its active position, characterized in that the operating member consists of a set of two links (7, 11) articulated together by a hinge joint (10), of which one (11) of the links comprises a thrust surface (11a) which is positioned in such a way that, in the active position, the thrust surface comes up against and carries along a peg (25) on the pawl (3), during the actuating movement, until the said pawl has been placed in the "escapement" position, and that in the inhibited position, the thrust surface at most comes into contact with the said peg, during the actuating movement so that the operating member has no action on the pawl, and of which the other link (7) is articulated to an opening lever (5), the electric device comprising a lock/unlock lever (15) co-operating with the hinge joint (10) to make it pivot about the articulation (8).
