Automotive vehicle HVAC rainhat

A high temperature injection molded polymeric rainhat for a heating, ventilation, and air-conditioning air intake of an automotive vehicle, the vehicle having a cowling with a generally planar surface, the planar surface encircling a flared opening in the cowling, the rainhat comprising:

• a flange for adhesively and sealably joining to a portion of the cowling generally planar surface encircling the flared opening, the flange has descending therefrom a plurality of elongated fastener members with compliant barbed heads for insertion into prepared holes in the cowling to connect the rainhat with the cowling;
• a heat expanding sealant adhesively and mechanically joined to the flange;
• a water dam integrally joined to the flange and extending therefrom, the water dam having an interior surface closely engaging the flared opening of the cowling and extending upwards beyond a vertical end of the flared opening, and the water dam having an extreme upper knife edge forming an opening and an interior surface of the water dam is tapered to an exterior surface of the water dam to form the upper knife edge, and an interior surface of the water dam has interior stops to make contact with an upper edge of the cowling flared opening;
• and
• a foreign matter ingestion preventer, the foreign matter ingestion preventer having a plurality of first curvilinear supports extending in a first direction over the water dam upper edge opening, each first support having opposite ends joined with the water dam, and each first support having a middle portion being domed above the opening of the water dam upper edge, each first support having the interior side and an exterior side with the exterior side being tapered, and the first supports exterior side being flush with the exterior surface of the water dam the foreign matter ingestion preventer having a plurality of second curvilinear supports intersecting with the first curvilinear supports, the second curvilinear supports extending in a second direction over the water dam, and each second support having opposite ends joined with the water dam, and each second support having a middle portion being domed above the opening of the water dam, each second support having an interior side and an exterior side with the exterior side being tapered and the second supports exterior side being flush with the exterior surface of the water dam, the foreign matter ingestion preventer further including first rafters generally parallel to the first supports, the first rafters extending in a first direction over the opening of the water dam, each first rafter having opposite ends joining with the water dam, each first rafter having a middle portion being domed above the opening of the water dam, each first rafter having opposite ends joining with the water dam, each first rafter having a middle portion being domed above the opening of the water dam and each first rafter having an interior side and an exterior side with the exterior side of the first rafter being tapered and the first rafter has ends flush with the exterior surface of the water dam, and the first rafter interior side being flush with an interior surface of the water dam, and the foreign matter ingestion preventer further including second rafters generally parallel to the second supports, the second rafters extending in a second direction over the opening of the water dam, each second rafter having opposite ends joining with the water dam, each second rafter having a middle portion being domed above the opening of the water dam and each second rafter having an interior side and an exterior side and the ends of the second rafter being flush with the interior and exterior surfaces respectively of the water dam, and the second rafter exterior side being tapered, the second rafters intersecting with the first curvilinear supports and rafters, and wherein the area of the foreign matter ingestion preventer minus the surface defined by the transverse dimensions of the area of the first and second supports and first and second rafters is equal or greater to the area defined by the opening of the water dam.

A single integral rainhat for a heating, ventilation, and air-conditioning air intake of an automotive vehicle, the vehicle having a cowling, the rainhat comprising:

• a flange for adhesively and sealably joining to a portion of cowling;
• a water dam integrally joined to the flange and extending therefrom, the water dam having an interior surface closely engaging the cowling and the water dam having an extreme upper edge forming an opening;
• and
• a foreign matter ingestion preventer, the foreign matter ingestion preventer having a plurality of first curvilinear supports extending in a first direction over the water dam upper edge opening and a plurality of second supports intersecting with the first curvilinear supports.
