A vehicle door assembly with an inner door panel, an outer door panel and a reinforcement assembly. A first attachment area is defined adjacent to an upper edge and a forward edge and a second attachment area is defined adjacent to the upper edge and a rearward edge of the inner door panel. The inner door panel and the outer door panel are fixedly attached to one another and define a hollow space therebetween. The reinforcement assembly has a first end fixedly attached to the first attachment area of the inner door panel and a second end fixedly attached to the second attachment area of the inner door panel. A mid-section extends of the reinforcement assembly extends along the upper edge of the outer door panel. The mid-section of the reinforcement assembly and the upper edge of the inner door panel define a window receiving slot therebetween.

Provided is an automobile door (600) including: a first impact absorbing member (122) that traverses the automobile door (600) so as to extend between both end portion regions in a vehicle height direction; a second impact absorbing member (124) that traverses the automobile door (600) so as to extend between both end portion regions in a vehicle length direction; an exterior material (110); and a belt line reinforcement (300), in which bending rigidity in a vehicle width direction of a cross section perpendicular to an extending direction of the belt line reinforcement (300) at a support portion is larger than bending rigidity in the vehicle width direction of a cross section perpendicular to an extending direction of the first impact absorbing member (122) at an intersection portion.

A hinge reinforcement comprises a reinforcement face portion which faces a door-hinge attachment face portion, an inside connection portion which longitudinally extends in a direction approaching a door center from an inside end portion, in a vehicle width direction, of the reinforcement face portion and is fixed to a door inside face portion, a first joint portion which longitudinally extends in the direction approaching the door center from the reinforcement face portion and is fixed to an impact bar, and a second joint portion which longitudinally extends in a direction away from the door center from an outside end portion, in the vehicle width direction, of the reinforcement face portion and is fixed to a door flange portion.

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 door structure includes an outer panel and an inner panel. A panel outer member of the inner panel includes a front longitudinal side portion extending in an upper-lower direction at a front end portion of the panel outer member, a rear longitudinal side portion extending in the upper-lower direction at a rear end portion of the panel outer member, a lower side portion that joins a lower end portion of the front longitudinal side portion to a lower end portion of the rear longitudinal side portion, connecting members that connect the front longitudinal side portion to the rear longitudinal side portion in a front-rear direction, and reinforcement members provided separately from the connecting members and joined to the connecting members in such a way as to extend in the front-rear direction along the connecting members and to form closed cross-sections in spaces with the connecting members.

A vehicle door assembly, having a first frame component including a window frame for a window opening and two opposing lateral frame for defining a frame cut-out and forming a sill portion connecting the two lateral frame portions to one another, a second frame component for strengthening the window frame, the second frame component fixed on the first frame component, and a door module carrier formed from an organosheet and at least partially closes the frame cut-out. The door module carrier forming an edge portion fixed to the sill portion in a longitudinal direction of the sill portion. The organosheet is a supporting structural component and an edge portion thereof is reinforced by a reinforcing structure injection-moulded onto the organosheet and the edge portion thereof strengthens the sill portion of the first frame component where no portion of the second frame component is provided.

A vehicle door assembly includes an outer panel and an inner panel. The outer panel has an inboard surface and an outboard surface. A door handle receiving area is disposed in the outer door panel and is configured to receive a door handle. The inner panel has an inboard surface and an outboard surface. The inner panel is connected to the outer panel. A first stiffener member is disposed beneath the door handle receiving area. A second stiffener member is disposed above the door handle receiving area.

Provided is an automobile door (600) including: a first impact absorbing member (122) that traverses the automobile door (600) so as to extend between both end portion regions in a vehicle height direction; a second impact absorbing member (124) that traverses the automobile door (600) so as to extend between both end portion regions in a vehicle length direction; an exterior material (110); and a belt line reinforcement (300), in which bending rigidity in a vehicle width direction of a cross section perpendicular to an extending direction of the belt line reinforcement (300) at a support portion is larger than bending rigidity in the vehicle width direction of a cross section perpendicular to an extending direction of the first impact absorbing member (122) at an intersection portion.

A door structure of a vehicle includes: an outer panel (4); an inner member (5, 11A) arranged on an inner side of the outer panel in a vehicle width direction; a rigid member (9) arranged between the inner member (5, 11A) and the outer panel (4); and a vibration suppression member (22) arranged between the outer panel (4) and the rigid member (9). The outer panel (4) includes a hem section (10f, 10r, 10u) disposed on a periphery thereof and connected to the inner member (5, 11A) by swaging. The vibration suppression member (22) includes a damping material (22A to 22C) located adjacent to the hem section (10f, 10r, 10u) and being in contact with the outer panel (4) and the rigid member (9).

A hinge reinforcement comprises a reinforcement face portion which faces a door-hinge attachment face portion, an inside connection portion which longitudinally extends in a direction approaching a door center from an inside end portion, in a vehicle width direction, of the reinforcement face portion and is fixed to a door inside face portion, a first joint portion which longitudinally extends in the direction approaching the door center from the reinforcement face portion and is fixed to an impact bar, and a second joint portion which longitudinally extends in a direction away from the door center from an outside end portion, in the vehicle width direction, of the reinforcement face portion and is fixed to a door flange portion.
