  • Spoiler arrangement on the rear of a motor vehicle
    Patent number: 5074612
    Abstract: A spoiler arrangement is arranged in the rear area of a fast back of a motor vehicle and, in the operative position, extends essentially above a rear window. So that the free design of the vehicle body is not impaired significantly and an effective protection of the spoiler arrangement is ensured when driving through an automatic car wash installation, the adjustably constructed spoiler arrangement is formed by a partial area of the rear window, the partial area in the retracted inoperative position, extending flush with the skin with respect to the adjacent rear window section.
