  • Hood structure
    Patent number: 6231110
    Abstract: A rear window is provided as a curved window, curved with an arc-like shape in the car width direction, with flexible frames disposed parallel along the upper side and the lower side of the curved window, mounted to a convertible top or hood. The flexible frames regain the straight shape at the time of folding the rear window so as to eliminate the curvature of the rear window in the car width direction as well as a linear fold can be formed in this direction without forming disadvantageous folds.
