Abstract
An air flow directing seal with integrally formed attachment member for attaching a seal to an automotive fan shroud is disclosed. The seal further includes an integrally formed flag portion which directs the flow of air from the radiator to the fan shroud. The attachment member includes a semi-rigid C-shaped channel that is made of a talc filled polypropylene material and further includes flexible resilient teeth integral with the inside surfaces of the C-shaped channel which aid in gripping the seal to a linear edge of the automotive fan shroud. The seal is made by a dual extrusion process whereby two types of thermoplastic materials are utilized having various physical properties in accordance with the desired specification. The flexible resilient teeth and the flag are made of the same thermoplastic rubber and the C-shaped channel is made of polypropylene during the same extrusion process. Thus, the teeth and the flag extend the entire length of the seal. The seal may be easily snapped to the shroud wherein the resilient teeth firmly grips the shroud which causes the seal to be secured to the shroud.
