초록 ▼

A lightweight, composite beam for reinforcing a vehicle door is provided. The reinforcing beam comprises an open channel-shaped metal member having a longitudinal cavity which is filled with a reinforcing polymeric material which in one aspect is a thermoset or thermoplastic resin-based material. The composite beam includes end pieces which are adapted to be mounted to a vehicle door panel in a door cavity by spot-welds or the like. The horizontally mounted beam provided substantially increased resistance to side impacts to the vehicle door in the event of a collision. In one embodiment, the beam is mounted between the window glass space and the inner door panel for flush-glass vehicle doors. In another configuration, one surface of the beam is sculptured to mate with a concise outer door panel.

대표청구항 ▼

A lightweight, composite reinforcing door beam adapted to be mounted in the cavity of a motor vehicle door which has an outer panel and an inner panel, the door beam providing structural reinforcement in the form of increased side-impact resistance when mounted in the cavity of the vehicle door, the door beam comprising: a body having a longitudinal axis, said body including a first wall and a second wall, said first and second walls extending in the direction of said longitudinal axis and spaced from one another in opposed relation; said body further including a generally U-shaped portion integral with said first and second walls, said generally U-shaped portion being co-extensive with said first and second walls in the direction of said longitudinal axis; said first and second walls and said generally U-shaped portion defining a channel-shaped area in said body, said channel-shaped area extending in the direction of said longitudinal axis; a core disposed in said channel-shaped area of said body, and core substantially filling said channel-shaped area in rigid contact with said first and second walls and with generally U-shaped portion; first and second mounting means attached to opposite ends of said body and adapted for mounting the door beam in the cavity of the vehicle door, with the longitudinal axis of the door beam positioned horizontally with respect to the vehicle door, thereby increasing the side-impact resistance of the vehicle door; and one of said first and second walls being curved outwardly along said longitudinal axis.
