The present invention relates to a motor vehicle door lock comprising: a forked latch (,) intended to interact with a striker; a pawl (,) which normally locks the latch in the closed position and which can adopt an &ldquo;escapement&rdquo; position in which it no longer acts on the said latch (,); a latch-release mechanism comprising 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 &ldquo;escapement&rdquo; position, or an inhibited position in which, during its actuating movement, 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 by the user; and an electric device which responds at least to an unlock signal by moving the operating member (,) from its inhibited position until it reaches its active position, characterized in that the lock further comprises a camming mechanism (,) which, when the unlock signal is transmitted more or less at the end of the actuating travel of the operating member (,), brings the pawl (,) into its &ldquo;escapement&rdquo; position.

Electrically locked motor vehicle door lock

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).

Lock comprising a rotary latch and a pawl for retaining the latch; external opening control rod and internal opening control rod for acting on the pawl by way of an intermediate lever and an electric drive. The intermediate lever has one end connected to the pawl. The lever being articulated in such a way as to be able to pivot at least about two different axes forming an angle between them. A pivoting of the lever about a first direction permits the locking function to be performed, a pivoting of the lever about the second direction permits the child safety function to be performed, and a combined pivoting of the lever about the first and second directions permits the double-locking function to be performed, so that the electric drive has only to control two movements in order to execute the three functions: locking, child safety and double-locking.
