Abstract

A lightweight door for vehicles comprises a door box having a top portion delimited by inner and outer window gutter profiles. A lightweight window frame is coupled to the door box and is formed of light metal or light metal alloy. The window frame is formed from an extruded bent profile that has a closed hollow chamber and at least one mounting formation. The mounting formation may include a mounting groove or a clip-on strip. The mounting formation continuously follows a length of the profile and is for receiving at least one add-on component. A plastic molded panel module is coupled to the frame. The module has a support surface and outer panels formed as a single piece along the frame adjacent a roof rail and a B-pillar of the motor vehicle.
