1. A thrust reverser for a nacelle of an aircraft turbojet engine, the thrust reverser comprising:

  • a thrust reverser cowl movable in translation along a direction substantially parallel to a longitudinal axis (A) of the nacelle between a direct jet position and a reverse jet position;

    a variable-section outlet nozzle arranged in a downstream extension of said thrust reverser cowl and movable between at least one reduced-section ejection position and one increased-section ejection position;

    an actuator comprising a body mounted on a fixed structure of the thrust reverser and an actuating rod, said actuating rod being adapted to drive the variable-section outlet nozzle and the movable thrust reverser cowl in displacement;

    a first device for locking the thrust reverser cowl in the direct jet position on the fixed structure of the thrust reverser, the first locking device comprising a locking hook pivotally mounted about a transverse axis (B), between a closed cowl locking position in which the locking hook cooperates with a locking pin secured to the thrust reverser cowl, and an unlocking open position of the thrust reverser cowl in which the locking hook releases said locking pin;

    a second device for locking the variable-section outlet nozzle on the thrust reverser cowl, the second locking device adapted to alternately occupy a position of locking the variable-section outlet nozzle on the cowl and a position of unlocking the variable-section outlet nozzle; and

    a reset lever pivotally driven by the locking pin about a transverse axis (B) from a rest position to a reset position, the reset lever being pivotally linked on the locking hook in a direction of closure of the locking hook, such that pivotal driving of the reset lever by the locking pin towards the rest position drives the locking hook towards the locking position,wherein the reset lever includes an actuating arm movably mounted on the thrust reverser cowl between the locking position of the variable-section outlet nozzle in which said arm actuates the second locking device to lock the variable-section outlet nozzle on the thrust reverser cowl, and the unlocking position of the variable-section outlet nozzle in which said arm unlocks the nozzle, said arm being driven in the locking position by the locking hook during pivoting of the locking hook towards the unlocking position.
