A door beam for a vehicle may include a beam portion having a rod shape which extends along a longitudinal direction of a vehicle body, a front mounting portion disposed at a front end portion of the beam portion to mount the front end portion of the beam portion to the door, and a rear mounting portion disposed at a rear end portion of the beam portion to mount the rear end portion of the beam portion to the door.

An impact beam and a method of producing the impact beam for a motor vehicle is disclosed. A light metal profile with an extrusion width is produced by flattening the light metal profile to a working width and cutting to length to form semi-finished products. The semi-finished products are subjected to further treatment by press-forming techniques to form the impact beam. The impact beam has a longitudinal length which extends transversely to the direction of extrusion of the light metal profile.

This structural member is manufactured using a structural member manufacturing device including a first clamping part having a first lower clamping member and a second upper clamping member disposed to face each other and capable of being opened and closed; a second clamping part having a third lower clamping member and a fourth upper clamping member disposed to face each other corresponding to the first lower clamping member and the second upper clamping member and capable of being opened and closed; and clamping part driver for allowing the first clamping part and the second clamping part to be relatively separated from each other while causing a position in an X-axis direction and a position in a Z-axis direction to correspond to each other.

A vehicle door structure includes a reinforcing member that is extended along a side sill on an inner door panel side of a lower portion of an outer door panel. The reinforcing member has a first side surface that faces the side sill in the vehicle width direction, and a second side surface that extends from the first side surface to the outer door panel, and the first side surface and the second side surface are joined to the inner door panel.

Provided is a method of manufacturing a vehicle skeleton member, the skeleton member including one or more groove-shaped portions extending in a predetermined direction, the method including an extrusion step and a press-working step. In the extrusion step, a sheet-shaped member including one or more first sheet-shaped portions each having a band-like shape, which extend in the predetermined direction, and second sheet-shaped portions each having a band-like shape, which extend in the predetermined direction along end portions of the first sheet-shaped portion in a width direction of the first sheet-shaped member and each have a sheet thickness smaller than a sheet thickness of the first sheet-shaped portion, is manufactured by using an extrusion molding method. In the press-working step, the sheet-shaped member is pressed so that at least part of a bottom wall portion of the groove-shaped portion is formed of the first sheet-shaped portion and side wall portions of the groove-shaped portion are formed of the second sheet-shaped portions, respectively.

An arrangement for the transfer of collision forces possibly resulting from a crash event from one body part to another body part of a motor vehicle, with a hollow profile acting as a crash profile, which hollow profile runs in the main direction of travel or transversely to the main direction of travel is loaded on pressure in the case of the crash event, and is frontally supported on each of the body parts. The hollow profile is frontally supported on the respective body part by means of interposition of in each case a load transfer element.

A structural beam for a motor vehicle comprising at least one roll formed sheet made of a heat-treatable aluminium alloy, wherein said structural beam has at least one closed chamber and has minimum a tensile yield strength of at least 420 MPa.

A method for fabricating a micro-truss structure having particular application for a vehicle impact structure. The method includes providing a thin support enclosure having a plurality of walls, where at least one of the walls is transparent to ultraviolet (UV) light. The support enclosure is filled with a liquid photomonomer resin and light from at least one UV source is directed through apertures in a mask and through the at least one transparent wall into the enclosure so as to polymerize and at least partially cure columns of the resin therein to form polymerized struts defining a micro-truss core in the enclosure that is secured to the walls. The support enclosure is then inserted into an outer structural enclosure.

A vehicle door including a door inner and a reinforcing beam fixed to the door inner. The reinforcing beam includes a first layer and a second layer bonded to each other. The first layer includes a polymer and fibers impregnated in the polymer and extending continuously across the polymer of the first layer. The first layer extends along an axis and has first and second ends spaced from each other on the axis. The second layer includes a polymer and fibers impregnated in the polymer and extending continuously across the polymer of the second layer. The second layer has first and second ends spaced from each other on the axis. The first and second ends of the second layer are each disposed between the first and second ends of the first layer along the axis.

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.
