Abstract:
A door having a latch mechanism is provided. The door also includes a bracket, and a pawl having a first aperture. The pawl is rotatably attached to the bracket and is operatively connected to the latch. The door additionally includes a key-cylinder adapted to selectively lock and unlock the latch by rotating the pawl, and a shield having a second aperture. Furthermore, the door includes a component connected to the key-cylinder. The component is aligned with and extends through the first and second apertures without contact with the pawl or with the shield, and is configured to not impede the rotation of the pawl by the key-cylinder when the component is aligned with the first and second apertures. The component is also configured to detach the pawl from the bracket and limit the key-cylinder extraction, when the key-cylinder is forcibly manipulated thereby causing the component to contact the shield.
