Abstract: The lock comprises: a fixed bush which defines a cylindrical cavity within which a cylinder rotating about the longitudinal axis of the cavity is mounted; a spring for retaining the cylinder within the cavity in the axial direction, the spring being interposed between a first circumferential groove made in the external lateral surface of the proximal portion of the cylinder and a facing slot made in the wall of the cavity; and interference means suitable for preventing the rotation of the cylinder within the cavity when the cylinder is pushed towards the distal extremity of the bush. A plurality of circumferentially spaced reliefs, extending each for an arc of a circle, radially protrude from a circumferential section of the external surface of the proximal portion of the cylinder, which reliefs bear in normal conditions against a circumferential flange which radially protrudes inwards from the internal surface of the bush.

Abstract: A handle for a vehicle door has a frame fittable to the door; a manual control lever connected to the frame and having a control portion connectable mechanically to a lock on the door; and an electric control assembly for activating a security function of the lock; the control assembly having a switch, a lever transmission interposed between the control portion and the switch, and a flexible positioning device for keeping the lever and the relative control portion in an intermediate rest position between an extracted release position, wherein the control portion releases the lock, and a forward switching position, wherein the control portion is pushed towards the frame to switch the switch.

Abstract: A handle for a vehicle door has a frame fittable to the door; a manual control lever connected to the frame and having a control portion connectable mechanically to a lock on the door to release the lock; and an electric control assembly for electrically controlling the lock to activate a security function of the lock; the control assembly having a switch, a push-button activating device for activating the switch and carried by the control portion, and a fluidtight sealing device associated with the control portion to prevent the passage of external contaminants towards the frame.
