Abstract
Abstract In order to mount a sunshine roof assembly in the roof of a vehicle a mounting ring 10 is fitted in an aperture in the vehicle roof. The mounting ring has a downwardly extending flange 20 on three of its sides which project through the aperture in the vehicle roof. The fourth side 22 is of U-shaped cross-section so as to embrace the corresponding edge of the aperture. The mounting ring is fitted into the aperture from above and secured to the vehicle roof. The sunshine roof assembly is then fitted from below and secured to the downwardly extending flange 20 on three of the sides of the aperture.
