A door beam including an inner flange extending in a longitudinal direction, an outer flange extending in the longitudinal direction and facing the inner flange at a distance from the inner flange, and-a pair of webs connecting the inner flange and the outer flange. The inner flange has an end portion in the longitudinal direction which is made closer to an end portion of the outer flange such that the distance between the inner and outer flanges at the end portions is shorter than the distance at other portions of the inner and outer flanges.

An Al-steel assembly is provided. The assembly includes an aluminum-based element and a steel element on at least one surface of the aluminum-based element. The steel element has a metal coating made of a zinc-aluminum-magnesium alloy and includes from 2.3% to 3.3% by weight of magnesium and from 3.6% to 3.9% by weight of aluminum. A coated surface of the steel element is in contact with the aluminum-based element in an assembly zone and a protective coating coats the assembly around and adjacent the assembly zone. A body-in-white, further assembly and method are also provided.

A press forming apparatus that produces a character line in a design surface of an outer panel by press forming includes an upper die and a lower die. The upper die has a die surface that is configured to form a design surface of an outer panel. The lower die has a die surface corresponding to the die surface of the upper die. The die surface of the lower die has, in a formation area of the character line, a curved convex portion that protrudes beyond an offset line of the die surface of the upper die and curved concave portions continuous with the curved convex portion. Each of the curved concave portions is on a corresponding one of both sides of the convex portion and is recessed beyond the offset line.

Guide rails with which a window regulator is provided are respectively fixed to a module plate. The guide rails are fixed, together with the module plate, to an edge of an opening portion provided at inward frames from an outward side in a vehicle width direction. Attachment portions which are capable of afterward attaching outward frames to the inward frames are provided, and attachment portions which are capable of afterward attaching a door outer panel to a door frame comprising the inward frames and the outward frames are provided.

A main body (2) has door attaching portions respectively formed on both end sides of a long longitudinal direction thereof and a bending deformation generation portion (3) disposed between the door attaching portions, and the bending deformation generation portion (3) has a groove bottom portion (4), two edge line portions (5a, 5b), two vertical wall portions (6a, 6b), two curved portions (7a, 7b), and two flanges (8a, 8b). There is provided a bead (13) which is formed toward the longitudinal direction of the main body (2) in a part of the groove bottom portion (4) in a manner to project in a shape having a curved surface toward the outside of a cross-sectional shape of the bending deformation generation portion (3) so as to oppose an impact load acting on a door impact beam (1).

A door of a vehicle may include a first door module forming a door skeleton, and a second door module coupled with the first door module and forming a door window wherein the second door module includes a relatively lightweight material as compared to the first door module, reducing weight and cost of the door for a vehicle.

A door of a vehicle may include a first door module forming a door skeleton; and a second door module coupled with the first door module and forming a door window, wherein the second door module includes a relatively lightweight material as compared to the first door module; and a reinforcement member is along an edge portion forming the door window of the second door module, reducing weight and cost of the door for the vehicle.

A door of a vehicle may include a first door module forming a door skeleton, a second door module coupled with the first door module and forming a door window, wherein the second door module may include a relatively lightweight material as compared to the first door module and a hollow portion is formed along an edge portion of the second door module forming the door window, reducing weight and cost of the door for a vehicle.

An intermediate shell for a motor vehicle door, in particular a side door of a motor vehicle, is disclosed. The intermediate shell is produced at least in regions from a light metal blank by massive forming, preferably by forging.

A door beam includes an aluminum alloy extrusion body extended in a longitudinal direction and having a pair of webs and a pair of flanges to be positioned on an inner side and an outer side in a width direction of a vehicle body. The pair of webs connect the pair of flanges at joint portions of each of the pair of webs such that the pair of webs and the pair of flanges form a closed cross section in a direction perpendicular to the longitudinal direction, and the pair of webs do not have a welded portion.
