  • Plastic fender for motor vehicles
    Patent number: 5271658
    Abstract: A plastic fender is stiffly and immovably attached to the body of a motor vehicle. The fender includes an attachment flange and a washer to be positioned between the fender attachment flange and a screw head. The washer includes at least one spherical cup-shaped impression that is pressed into the fender, resulting in positive locking which prevents movement of the fender. Stiff attachment can also be provided by a steel rail embedded in the attachment flange or steel rails attached to the sides of the attachment flange or by embedding the flange in a relatively stiff retaining part.
