<p>The trapdoor (1) has a case (2) including a flap (6) mounted pivotably between a closed position in which it seals an external opening of the case and an open position in which it releases the opening and gives access inside the trapdoor. A motorized or manual actuator (10) moves a locking pin (11) cooperating with a reserve hook (12), translationally. The hook is placed under the flap. The actuator is adapted to control retraction of the locking pin, which releases the hook. The hook is assembled swiveling under the flap, and is solicited in rotation by a return spring. The actuator is an electric linear actuator.</p> |
