The inner side member includes: a fixing part fixed to the beam body; and a non-fixing part not fixed to the beam body and being disposed at a position in front of the fixing part in the front-rear direction.

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.

The invention relates to a door (3) of a motor vehicle (1), having an outer wall and a lining (7) forming a casing (9), said casing (9) comprising: a main side reinforcement (17) extending longitudinally between a front edge (9A) and a rear edge (9C) of said casing (9); an upper reinforcement (15) extending longitudinally along an upper edge (9B) of said casing (9); an exterior opening control support (11) of the door (3), which is fixed to the upper reinforcement (15); the casing (9) further comprising: an auxiliary side reinforcement (21) which extends above the main side reinforcement (17) longitudinally between the front edge (9A) and the rear edge (9C) of the casing (9) and is fixed to the control support for the exterior opening (11) of the door (3).

A vehicle-door reinforcement includes a first beam elongated along an axis between a first end and a second end. The vehicle-door reinforcement includes a hinged beam elongated along the axis. The hinged beam includes a first segment and a second segment hinged to each other. The first segment is engaged with the first beam and the second segment is slideably engaged with the first beam. The vehicle-door reinforcement includes an actuator fixed to the first beam and connected to the second segment.

A center pillar structure may include a center pillar inner upper connected to a side inner, a center pillar inner connected to the center pillar inner upper in up and down directions, a center pillar reinforcement outer connected to a front pillar reinforcement outer and connected to the center pillar inner along the up and down directions, a center pillar reinforcement disposed along the up and down directions on the inner side between the center pillar inner and the center pillar reinforcement outer, and coupled between front/rear flange combined portions of the center pillar inner and the center pillar reinforcement outer, and a seat belt reinforcement shaped corresponding to the center pillar reinforcement, and connected to the center pillar reinforcement to form an inner closed section along the up and down directions.

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 door beam including an aluminum alloy extruded material of a closed section structure having a welded part along the longitudinal direction, webs and an outer flange are inhibited from buckling and further the welded part in the outer flange is inhibited from breaking at the time of collision. In a cross section of an aluminum alloy extruded material perpendicular to the extrusion direction, each of the webs includes an outer part connected to the outer flange and an inner part connected to an inner flange and the thickness of the outer part is larger than the thickness of the inner part. Each of the outer parts is positioned in a region outside a cross section center of the aluminum alloy extruded material in the vehicle body width direction.

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.

The present invention provides a shock-absorbing member including: an exterior material 110 for an automobile; a first reinforcing member 122 that is disposed adjacent to the exterior material 110 and whose cross section orthogonal to the extending direction has a height, in the direction orthogonal to the exterior material 110, that is greater than the width in the S direction along the exterior material 110; a second reinforcing member 124 that is disposed adjacent to the exterior material 110 and whose cross section orthogonal to the extending direction has a height, in the direction orthogonal to the exterior material 110, that is greater than the width in the direction along the exterior material 110; an intersecting part where the first reinforcing member 122 and the second reinforcing member intersect and overlap; and a joint that joins the first reinforcing member 122 and the second reinforcing member 124 at the intersection.
