There are provided an outer member, an inner member including a front-side vertical wall portion and a rear-side vertical wall portion, an impact bar extending from front-side attachment portions of the front-side vertical wall portion to rear-side attachment portions of the rear-side vertical wall portion, a hinge-reinforcement member reinforcing a hinge attachment portion where a hinge is attached to the front-side vertical wall portion, and a latch-reinforcement member reinforcing a latch-attachment portion where a latch device is attached to the rear-side vertical wall portion. The front-side vertical wall portion and the rear-side vertical wall portion are made of casting or high-strength resin, and the hinge-reinforcement member and the latch-reinforcement member are configured to have higher ductility than the front-side vertical wall portion and the rear-side vertical wall portion and connected to the impact bar.

Guide rails with which a window regulator is provided are respectively fixed to a module plate. The guide rails are fixed, together with the module plate, to an edge of an opening portion provided at inward frames from an outward side in a vehicle width direction. Attachment portions which are capable of afterward attaching outward frames to the inward frames are provided, and attachment portions which are capable of afterward attaching a door outer panel to a door frame comprising the inward frames and the outward frames are provided.

An inner door panel (30) for a vehicle side door that includes an integrated side impact beam (70) formed as part of the door in a die casting process. The inner door panel (30) includes an outer frame having a top rail (38), a bottom rail (40), an inner side rail (42) and an outer side rail (44) defining a central opening (34). The impact beam (70) includes a main beam portion (72), a first end support portion (74) and a second end support portion (78). The first end support portion is formed to the side rail (42) and the second end support portion (78) is formed to the outer side rail (44), where the main beam portion (72) extends across the opening (34).

There are provided an outer member, an inner member including a front-side vertical wall portion and a rear-side vertical wall portion, an impact bar extending from front-side attachment portions of the front-side vertical wall portion to rear-side attachment portions of the rear-side vertical wall portion, a hinge-reinforcement member reinforcing a hinge attachment portion where a hinge is attached to the front-side vertical wall portion, and a latch-reinforcement member reinforcing a latch-attachment portion where a latch device is attached to the rear-side vertical wall portion. The front-side vertical wall portion and the rear-side vertical wall portion are made of casting or high-strength resin, and the hinge-reinforcement member and the latch-reinforcement member are configured to have higher ductility than the front-side vertical wall portion and the rear-side vertical wall portion and connected to the impact bar.

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.

Guide rails with which a window regulator is provided are respectively fixed to a module plate. The guide rails are fixed, together with the module plate, to an edge of an opening portion provided at inward frames from an outward side in a vehicle width direction. Attachment portions which are capable of afterward attaching outward frames to the inward frames are provided, and attachment portions which are capable of afterward attaching a door outer panel to a door frame comprising the inward frames and the outward frames are provided.

A main body for a motor vehicle door which is produced by injection molding and has a frame, which has an upper reinforcing element, which has flanges that protrude from the upper reinforcing element. It is proposed for the upper reinforcing element to be integrally formed in one piece on the frame via at least two articulation elements in a manufacturing position in which said upper reinforcing element protrudes from the frame.

A motor vehicle door and a method for producing the motor vehicle door is disclosed having a frame plate coupled to reinforcement components and at least half of all of the reinforcement components are produced as extruded profiles which are subsequently press-formed three-dimensionally. The extruded profiles have different wall thicknesses.

A method for manufacturing an inner door panel for a vehicle side door that employs a die casting process. The method includes providing a die cast mold having opposing mold halves that combine to define a die cavity configured to provide the inner door panel. An impact beam is positioned in the mold cavity prior to combining the first mold half and the second mold half, and a molten metal is provided to the mold cavity so that molten metal flows into all areas of the mold cavity and around the impact beam after the first mold half and the second mold half are combined. A solidified molded inner door panel is then removed from the die cast mold that includes an encapsulated impact beam.
