Electric lock for a motor vehicle door
First Claim
1. Electric lock for a motor vehicle door, comprising a lock casing (B), of which a first compartment (3), known as the retention compartment, contains a latch (4) capable of retaining a striker and a pawl (5) for immobilizing the latch in a striker-retaining position, and of which a second compartment (15), known as the driveline transmission compartment, contains, in sealed manner, a locking mechanism comprising a locking lever (41) capable of placing the lock in a locked/unlocked position, and an opening mechanism comprising an electric motor (16) for assisting with opening, characterized in that, in the second, driveline transmission, compartment (15), the electric motor (16) is coupled, via a set of gears (17-19), to a gear wheel (22) having at least one radially eccentric wrist pin (24) and a radially eccentric peg (23a), said wrist pin being able to engage an operating lever (11) in said second, driveline transmission compartment (15), so that when the electric motor (16) is supplied with electrical power, the electric motor rotates said gear wheel (22) and, as said gear wheel rotates, said wrist pin (24) drives said operating lever (11) until said radially eccentric peg (23a) on said gear wheel comes into contact with an elastic end-of-opening travel stop (27), the supply of electrical power to the motor being timed to last long enough to ensure said peg reaching the elastic stop, said operating lever rotating as one with an opening lever (9) arranged in the first, retention, compartment (3) and capable of cooperating with the pawl (5) to move said pawl into a releasing position for releasing the latch (4).

Abstract
Electric lock for a motor vehicle door, comprising a lock casing (B), of which a first compartment contains a latch and a pawl, and of which a second compartment (15) contains, in sealed manner, a locking lever (41) capable of placing the lock in a locked/unlocked position, and an electric motor (16) for assisting with opening, characterized in that, in the second compartment, the electric motor is capable of rotating, via a set of gears (17-19), a gear wheel (22) with at least one radially eccentric wrist pin (24), the said wrist pin being intended, as the wheel rotates, to drive an operating lever (11) until a radially eccentric peg (23a) on the said wheel comes into contact with an elastic end-of-opening travel stop (27), the supply of electric power to the motor being timed to last long enough for the said peg to be sure of reaching the elastic stop, the said operating lever rotating as one with an opening lever arranged in the first compartment and capable of cooperating with the pawl to move it into the position for releasing the latch.
