ABSTRACT:
A vehicle ventilation opening is covered by a dome-shaped cover that has a pair of generally triangular oppositely disposed lateral cover openings extending from an uppermost portion of the cover. A pair of generally triangular shaped and outwardly bowed resilient doors are pivoted at opposite sides of the cover so that their adjacent but mutually spaced free end portions move between an inwardly displaced open position and a closed position wherein the free ends of the doors are at the high point of the domed cover and the doors seal against the inside of the cover at the peripheries of the openings. A compression spring is interposed between the adjacent free ends of the doors to force the doors against their hinged connections at the sides of the cover throughout all the positions of the doors and to facilitate an over-center toggle action which is provided by the resilient curved doors themselves to snap the doors to closed position and force them into sealing engagement with the peripheries of the cover openings.
