The vehicle door structure includes: a door outer panel including a projected section that projects outward in a vehicle width direction, a recessed section that is separated from the projected section and recessed inward in the vehicle width direction, and a boundary section between the projected section and the recessed section; and a panel reinforcement fixed to an inner surface in the vehicle width direction of the door outer panel. The panel reinforcement includes: a first frame section that extends in a vehicle front-rear direction; and a second frame section at a position that overlaps the boundary section in the vehicle side view and is configured to be able to transmit a load to the first frame section at the time when the load in an inward direction of the vehicle width direction is applied to the boundary section.

A door assembly for a motor vehicle comprised of an outer door panel and an inner door panel interconnected to define a door panel structure having an internal door cavity. A collapsible carrier module is configured to be oriented in a collapsed arrangement to facilitate installation into the door cavity through an opening in the inner door panel. The collapsible carrier module can be moved from its collapsed arrangement into an expanded arrangement upon installation within the door cavity to facilitate subsequent mounting to the door panel structure. The collapsible carrier module includes a two-piece carrier plate formed to integrally include a pair of laterally-spaced glass run channels and a pair of laterally-spaced slider rails.

The reinforcement element for reinforcing the structure of a door of a vehicle extends along a main direction and comprises at least a main portion having a reinforcing cross-section (40) extending in a plane substantially perpendicular to the main direction. The reinforcing cross-section (40) includes at least four adjacent branches (42a, 42b, 42c, 42d, 42e, 42f, 42g ), each extending in different directions, two successive branches forming a non-zero angle, at least two of the non-zero angles being of opposite signs.

An add-on part (1) of a vehicle body, such as a door (1) or tailgate, has interconnected inner and outer parts (2, 4) and reinforced portions (5, 6) and a reinforcing device (7) connecting said reinforced portions (5, 6). The reinforcing device (7) has arms (8, 9, 18, 19), and, in the region of the ends of the arms (8, 9, 18, 19), the reinforcing device (7) is connected in a force-fitting and/or form-fitting manner to the reinforced portions (5, 6). Such an add-on part, while having a structurally simple design and relatively low weight, ensures particularly good stiffening properties.
