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.

Provided is a configuration that makes up for a lack of tensile rigidity and a lack of collision properties at the same time. [Solution] An automotive exterior panel according to the present invention: an exterior material 110; and a reinforcing member 120 that is in contact along an automobile inside surface of the exterior material 110 and of which a second moment of area in a direction orthogonal to the exterior material is less than or equal to 15,000 mm4 in a cross section orthogonal to a longitudinal direction of the 10 reinforcing member. By this configuration, the second moment of area in a direction orthogonal to the longitudinal direction of the reinforcing member 120 is made less than or equal to 15,000 mm4, and hence a lack of tensile rigidity can be made up for at the same time.

A door of a vehicle may include a door internal panel; a door external panel mounted outside a passenger compartment with respect to the door internal panel, detachably coupled to the door internal panel, and made of a lightweight material than the door internal panel; and a reinforcement member mounted between the door external panel and the door internal panel and fastened to the door external panel and the door internal panel to increase rigidity, reducing weight and cost of the door of the vehicle and easily replacing the door external panel.

A side vehicle-body structure of a vehicle includes a rear door having a center pillar extending in a vehicle up-down direction built in a front portion of the rear door, and a front door having a door impact bar extending in a vehicle front-rear direction built in the front door. A rear end of the door impact bar is disposed to overlap with the center pillar in a vehicle side view, a reinforcement gusset that connects a lower portion of the front door and a rear portion of the door impact bar to each other is included in an inner portion of the front door, and a side sill extending in the vehicle front-rear direction is adjacently disposed below a connecting portion of a lower portion of the front door at which the lower portion of the front door is connected to the reinforcement gusset.

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 noise insulating support panel is provided for a structural assembly and includes a base substrate component and at least one localized stiffening reinforcement feature. The reinforcement feature generally extends across the base substrate component in a length direction aligned with, i.e., substantially parallel to, or substantially perpendicular to, a direction of airflow exhibiting turbulent pressure onto the base substrate component. The reinforcement feature cooperates with the base substrate component to minimize energy transmission through the base substrate component. If the base substrate component is a body panel, the reinforcement feature may be a stiffening rib member; if laminated glass, the reinforcement feature is located within an interlayer disposed between glass layers. The interlayer may include a first region including polyvinyl butyral having a first stiffness, and a second region including polyvinyl butyral having a second, lower stiffness. The reinforcement feature may also be an edge stiffening treatment.

A vehicle door assembly includes a door housing configured for covering a vehicle access opening. A frame member is disposed within the door housing. A module includes an intrusion beam coupled to the frame member and removable from the door housing. The module is configured to accept attachment of a module hinge and a module latch to provide a secondary door assembly. A modular vehicle door assembly and a method of assembling a door assembly to a vehicle are also disclosed.

A method includes molding an outer impact beam made of carbon fiber reinforced plastics (CFRP) and separately molding an inner impact beam made of CFRP. The outer impact beam and the inner impact beam are coupled to each other to form an impact beam and the impact beam is coupled to an inner panel of a vehicle door.

A vehicle door assembly includes a door housing configured for covering a vehicle access opening. An intrusion beam is within the door housing. A module is received on the intrusion beam and removable from the door housing. A module hinge assembly is attachable to the module. A module latch assembly is attachable to the module for securing the module to extend across the vehicle access opening.
