A motor vehicle with at least one vehicle door includes a reinforcement component arranged in the lower section of the door body of the vehicle door. The reinforcement component is an open profile with lateral walls and an M-profile formed thereon which extend in the vehicle transverse direction in order to absorb forces acting in the vehicle transverse direction in the event of a load.

A vehicle side body structure having a pillar member including an upper member and a lower member that is joined to the upper member and has a rigidity lower than the upper member, the pillar member partitioning a side part opening of a body into a front part and a rear part; a side door disposed adjacently to the pillar member; and an impact bar provided in the side door, in which a front end portion of the impact bar overlaps with both the upper and lower members in side view while the side door is closed. The upper member has a reinforcing member and the front end portion of the impact bar covers a region of the upper member in which the reinforcing member is present, a region of the upper member in which the reinforcing member is not present, and the lower member in side view.

A body structure including an A-pillar, a door assembly, an engine compartment assembly and an upper longitudinal beam of engine compartment, and also includes a reinforcement plate of upper longitudinal beam, a first anti-crash beam, and a second anti-crash beam. The front end of the reinforcement plate of upper longitudinal beam is connected to the middle portion of the upper longitudinal beam of engine compartment. The rear end of the reinforcement plate of upper longitudinal beam is connected to the engine compartment assembly. The upper longitudinal beam of engine compartment and the reinforcement plate of upper longitudinal beam form a first triangle area on the engine compartment assembly. The first anti-crash beam and the second anti-crash beam are installed on the door assembly along a direction from the front to the rear of the vehicle body. The first anti-crash beam is located above the second anti-crash beam.

A door beam of a motor vehicle includes a 7000 series aluminum alloy extruded material, the 7000 series aluminum alloy extruded material including Zn: 7.5 mass % to 9.0 mass %, Mg: 1.3 mass % to 2.0 mass %, Cu: 0.1 mass % to 0.7 mass %, Si: 0.15 mass % or less, Fe: 0.3 mass % or less, Ti: 0.005 mass % to 0.2 mass %, and at least one of Mn, Cr, and Zr: 0.1 mass % to 0.5 mass %, in which contents of Mn, Cr and Zr satisfy Mn: 0.3 mass % or less, Cr: 0.25 mass % or less, and Zr: 0.25 mass %, respectively, with the remainder being Al and impurities. A Fe-based crystallized product is contained, and an average Cu content of the Fe-based crystallized product is 5.0 mass % or less.

A door structure system for a vehicle includes an inner panel, an outer panel, and an outer belt reinforcement member. The outer belt reinforcement member extends in a fore-and-aft direction of the door structure. The outer belt reinforcement member creates an overlap joint with a hem flange portion of the inner panel. The outer belt reinforcement member includes touch-down feature that extends toward the inner panel and into contact with a bearing surface of the inner panel that is stepped down relative to the hem flange portion. The overlap joint and the touch-down feature both contribute to an increased upper frame stiffness of the door structure and improve sealing performance between the door structure and the vehicle body structure.

A vehicle door assembly include an inner door panel, a first hinge and a guard beam. The inner door panel has a first edge portion and a second edge portion. The first edge portion has a first hinge attachment location and a second hinge attachment location with the first hinge location having a first opening and a second opening. The first hinge is dimensioned and configured to attach to the first hinge attachment location of the inner door panel. The guard beam has a first end and a second end. The first end has a first fastener and a second fastener rigidly and non-movably attached thereto. The first fastener is inserted through the first opening and the second fastener extends through the second opening in the first hinge attachment location, the first and second fasteners further fastening to the first hinge thereby attaching the first hinge to the door panel.

A door structure includes a door panel, a first beam member, a first bracket attached to a rear end portion of the first beam member, a second beam member formed separately from the first beam member, a second bracket attached to a rear end portion of the second beam member and formed separately from the first bracket, and a coupling member, to which the first bracket and the second bracket are fixed to be arranged side by side, and which is attached to the door panel. The coupling member includes an extending portion extending in a vehicle width direction between the first bracket and the second bracket.

The present invention provides a panel for a vehicle including a coated steel sheet locally reinforced. A method for preparing the panel and the use of the panel are also provided.

An impact protection reinforcement of a vehicle construction, which is supportively fastenable in the vehicle construction against the action of external mechanical extraordinary load conditions and comprises the following features: an elongated profile element with a longitudinal center line and a transversal center line arranged transversely to the longitudinal center line, which has in the longitudinal direction at each end side a fastening end and a central part therebetween, wherein the central part consists of a circumferentially closed hollow profile with a base layer and a top layer arranged opposite to the base layer, which are connected to each other via lateral faces, and the fastening ends each have a flat shape with at least two fastening points which are spaced apart differently from the transversal center line and the longitudinal center line and are provided as welding connection points to the vehicle construction.

A door beam structure includes a door beam attached to a side door so as to extend along a longitudinal axis of a vehicle. The door beam has a curved shape extending outwardly along a transverse axis of the vehicle and is spaced apart from a door skin in an inward direction along the transverse axis as the door beam extends to opposite end portions, along the longitudinal axis, of the door beam. The door beam includes a first end portion located in a frontward direction along the longitudinal axis, the first end portion being opposite to a center pillar. The first end portion is provided with a crush box.
