Abstract
A vehicle door includes an outer panel and an inner panel of molded synthetic resin construction. The inner panel has a structural lower portion concealed beneath the outer panel and an upper portion integral with the lower portion and defining a window frame surrounding a window opening. A tubular reinforcement member of generally inverted U shape is embedded in the upper portion of the inner panel and has leg portions extending downwardly from the upper portion and embedded in the structural lower portion so that the structural lower portion connects the leg portions of the upper portion. The tubular member is a continuous hollow tube formed to have varying cross sectional shape along the continuous length to fit within the shape of the window frame. The synthetic resin of the upper portion is a reinforced reaction injection molded material providing a finished surface for painting and the synthetic resin of the lower portion is a structural reaction injection molded material providing relatively high strength and having a glass fiber mat embedded therein to span between the legs of the tubular member and facilitate bonding between the resin materials of the upper and lower porti…
