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.

[Object] 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 mm.sup.4 in a cross section orthogonal to a longitudinal direction of the 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 mm.sup.4, and hence a lack of tensile rigidity can be made up for at the same time.

A vehicle door structure includes: a metal door outer panel that includes an outermost design surface of a vehicle door; a metal annular reinforcement that (i) is provided at a door inner side of the door outer panel, (ii) has an annular shape so as to extend along an outer peripheral portion of the door outer panel, and (iii) is joined to the outer peripheral portion of the door outer panel; at least one reinforcing member that extends in a door longitudinal direction and that is joined to the annular reinforcement; and a fiber-reinforced door inner panel that is provided at a door inner side of the annular reinforcement, and is fastened to the annular reinforcement.

A vehicle includes a door with an interior door cavity, as well as a lock rod and another item of a locking system, an impact beam, an attack member and a push member, all housed in the interior door cavity. The impact beam crosses the other item from laterally between the other item and the door. The attack member faces the lock rod from laterally between the door and the lock rod. The push member, along the impact beam, faces the other item from laterally between the other item and the door and laterally beyond the impact beam. When the door collapses when compromised by a side impact event, the door carries the attack member for attacking action on the lock rod. The door additionally carries the push member for counterpart pushing action on the other item. A connection between the lock rod and the other item thus breaks.

An impact beam structure of a CFRP door for a vehicle is disclosed. A outer impact beam and an inner impact beam are separately molded and then coupled to each other such that an impact beam is formed. The impact beam is coupled to an inner panel of the CFRP door for the vehicle.

A vehicle side door internally includes an impact beam which extends along a longitudinal axis of a door. The impact beam is attached to a door inner panel via an outer extension. An inner extension is attached inside the outer extension. A distance along thickness of the door between the inner extension and the impact beam is shorter in a close proximity section than in a longitudinally neighboring area. Because the load received by the inner extension via the close proximity section is transferred to joint portions connecting to the outer extension, the load received by the outer extension from the impact beam is dispersed.

A door structure for a vehicle may include an external panel; an internal panel that is mounted to the external panel; and an impact member coupled to the internal panel between the external panel and the internal panel, wherein a protrusion that protrudes to an outside thereof toward a side external panel of a vehicle body from inside the internal panel is integrally provided in the impact member.

A rear side door 20 designed to open and close an opening formed in a body 40 includes an inner panel 21 and a door beam 24. The door beam 24 is mounted on an inner panel 21 through a bracket 25 placed between the door beam 24 and the inner panel 21, and a patch member 26 is disposed on a tip part 24A of the door beam 24 at a position overlapping the tip part 24A of the door beam 24 in the vehicle widthwise direction.

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.
