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.

A vehicle structure includes a body panel, a first spring anchor, a second spring anchor; and an elongated spring having a first end disposed at a first spring anchor and a second end disposed at a second spring anchor. The spring is preloaded when assembled to form an apex between the first end and the second end. The apex is disposed adjacent to the body panel to provide an outward force on the body panel.

An arrangement for the transfer of collision forces possibly resulting from a crash event from one body part to another body part of a motor vehicle, with a hollow profile acting as a crash profile, which hollow profile runs in the main direction of travel or transversely to the main direction of travel is loaded on pressure in the case of the crash event, and is frontally supported on each of the body parts. The hollow profile is frontally supported on the respective body part by means of interposition of in each case a load transfer element.

A vehicle structure includes a body panel, a first spring anchor, a second spring anchor; and an elongated spring having a first end disposed at a first spring anchor and a second end disposed at a second spring anchor. The spring is preloaded when assembled to form an apex between the first end and the second end. The apex is disposed adjacent to the body panel to provide an outward force on the body panel.

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 side portion structure that includes: a pair of rockers that, at vehicle side portions, respectively extend along a vehicle longitudinal direction at both outer sides in a vehicle transverse direction of a floor panel that is a floor portion of a vehicle cabin interior, first impact absorbing portions that form closed cross-sectional structures and that, at a time of a side collision of a vehicle, plastically deform and absorb collision energy being provided at interiors of the pair of rockers; and side doors that open and close door opening portions of the vehicle side portions, second impact absorbing portions, which form closed cross-sectional structures and, at the time of a side collision of the vehicle, plastically deform and absorb collision energy, being provided at lower portions of interiors of the side doors.

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 is disclosed that includes: an outer panel; an inner panel located inboard of the outer panel; a window channel; a window glass; a structural beam; and a reinforcement member supported by the inner panel and the structural beam so as to inhibit force transmission through the vehicle door during a side impact. The window glass is movable within a window slot collectively defined by the outer panel and the inner panel. The window channel is supported by the inner panel, extends in generally orthogonal relation to the window slot, and is configured to receive the window glass such that the window glass is movable therethrough. The structural beam is supported by the inner panel and defines a longitudinal axis. The structural beam is configured such that the longitudinal axis extends in generally parallel relation to the window slot and in generally orthogonal relation to the window channel.

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 portion structure that includes: a pair of rockers that, at vehicle side portions, respectively extend along a vehicle longitudinal direction at both outer sides in a vehicle transverse direction of a floor panel that is a floor portion of a vehicle cabin interior, first impact absorbing portions that form closed cross-sectional structures and that, at a time of a side collision of a vehicle, plastically deform and absorb collision energy being provided at interiors of the pair of rockers; and side doors that open and close door opening portions of the vehicle side portions, second impact absorbing portions, which form closed cross-sectional structures and, at the time of a side collision of the vehicle, plastically deform and absorb collision energy, being provided at lower portions of interiors of the side doors.
