Latch structure, in particular for an automobile vehicle

A latch structure, in particular for an automobile vehicle door, the latch structure comprising a case, a mechanism of the latch structure disposed within the case, and a keeper which is movable in a given direction relative to the case, said mechanism comprising a bolt means mounted to pivot about an axis substantially perpendicular to said given direction of movement of the keeper, said bolt means comprising means defining a fork-shaped portion which is cooperable with the keeper, a movable lever for actuating the latch structure, a locking means interposed between the bolt means and the actuating lever, the actuating lever being associated with the bolt means to allow rotation of the bolt means in a direction for releasing the keeper through the locking means, the locking means being mounted to be movable in a first element of two elements consisting of the bolt means and the actuating lever, between a projecting position for rendering said elements interconnected and a retracted position for allowing the free movement of rotation of the bolt means relative to the actuating lever, the second of said two elements defining, for rendering said elements interconnected, at least one notch which the locking means is capable of penetrating, and said two elements being mounted in such manner as to be capable of moving away from each other for allowing the locking means to leave the notch defined by said second element, said first element being said bolt means and said second element being said actuating lever, which lever is mounted in the case to pivot about an axis parallel to the axis of the bolt means, said actuating lever being provided with a spring which biases the lever in a direction which moves the actuating lever away from said bolt means and the actuating lever being cooperative with an operating device which comprises a cam allowing temporarily the movement of the actuating lever away from the bolt means when unlocking the latch structure for the purpose of releasing said locking means from said notch.
