Abstract: Described herein is a lock for a door of a motor vehicle provided with a closing mechanism designed to cooperate with a lock striker fixed to an upright of the door itself; the closing mechanism is provided with: a fork, which can assume an opening position, in which it enables engagement and disengagement between the lock striker and a seat thereof, and a closing position, in which it withholds the lock striker within its seat and prevents disengagement thereof; a dog coupled via snapaction with the fork for blocking it in a releasable way in the closing position; and an auxiliary lever, which can be actuated by the fork during coupling with the lock striker for exerting an action of thrust on the dog and causing it to couple with the fork itself.

Abstract: A lock for a door of a motor vehicle is provided having: a closing mechanism designed for coupling with a lock striker for bringing about closing of the door; mechanical opening means for controlling release of the closing mechanism from the lock striker; mechanical means for inhibiting opening which can be selectively activated for rendering the opening means ineffective; and electrical actuator means housed in a fluid-tight way in a single casing having at least one output member which traverses, in a fluid-tight way, a through hole of the casing to interact with the means for inhibiting opening.

Abstract: An angular connection for a frame or counterframe composed of hollow sections of plastic material includes at least one plastic angular element inserted with its two legs fitting firmly in the hollow sections at the point at which they converge. The walls of the sections are welded to the legs of the insert by ultrasonic spot welds. A second plastic insert may be provided for connecting together edges of the sections, the first plastic insert being arranged to connect the main bodies of the sections together. Both inserts are connected to the hollow sections by ultrasonic spot welds. A method of making an angular connection for a frame and counterframe includes the step of welding hollow sections to at least one plastic angular element using ultrasonic welding techniques.
