  • Vehicle rear window arrangement
    Patent number: 4195874
    Abstract: A vehicle is provided with a rear window arrangement having first and second rear window portions at different angles from the vertical, and a spoiler with an upper deflection surface having an angle of at least 90.degree. from the vertical. The two portion rear window arrangement provides increased rearward visibility and decreased vehicle wind resistance. The spoiler may be arranged to form a flow channel around the edge where the two window portions meet, to deflect an air stream and prevent accumulation of dirt on the lower rear window portion.
