Windshield air deflector for a motor vehicle

摘要

An air deflector device configured for mounting on the hood of a motor vehicle adjacent a windshield for deflecting air away from the windshield as the vehicle moves rapidly forward. This deflector device comprises an elongate deflector member configured to be mounted substantially horizontally on the hood of the vehicle, transverse to its central, longitudinal axis (the deflector member having a forward edge and a rearward edge when so mounted); and a hinge on the forward edge of the deflector member to enable the rearward edge of the member to be raised and lowered in front of the windshield. A drive or spring bias mechanism may also be provided to raise and lower the member between a first position in which it is substantially parallel (e.g., flush) with the surface of the hood and a second position, with the rearward edge raised, in which the member deflects air upwards and away from the windshield.

主权项

1. An air deflector device configured for mounting on a front hood of a motor vehicle adjacent a windshield for deflecting air away from the windshield as the vehicle moves forward, said deflector device comprising:
(a) at least one elongate deflector member configured to be mounted substantially horizontally on the hood transverse to the central, longitudinal axis of the vehicle, said deflector member having a forward edge and a rearward edge when so mounted, the deflector member having an upper surface facing away from the hood when mounted thereon and at least one opening in said upper surface for the egress of air; and (b) an air blower and an air pipe for directing forced air to said deflector member for egress through said at least one opening, thereby creating a smooth lateral flow of air over the deflector member by means of the Coanda effect.
