Abstract
Abstract In an air duct assembly, the air duct is integrally provided with a harness sheath which is formed with a laterally openable, longitudinal slit adapted to permit the harness to be inserted in the sheath and retained therein. The harness sheath may be molded, integrally with the air duct, of a polyethylene resin by blow-molding, for example. The air duct is a defroster duct which extends transversely across the passenger comparment of an automobile.

Claim 1
Independent Claim
199 words
In an automobile having a passenger compartment, an air duct assembly, comprising: a harness; a defroster duct molded of a plastic material, said defroster duct being disposed at a forward part of said passenger compartment, extending transversely across said automobile, and having a bottom; and a harness sheath provided at said bottom of said defroster duct, said harness sheath being molded of said plastic material integrally with said defroster duct and having a wall formed with a laterally openable, longitudinal slit, said harness sheath being sufficiently flexible such that when said harness is placed in substantially aligned contact with said slit and is forced into said sheath through said slit, said wall of the sheath is flexed such that said slit is laterally opened to permit the harness to pass through said slit into said sheath, and the harness being received in said sheath, is covered over a substantial length by said sheath so that said sheath serves as a protector for the harness to prevent the harness from coming into contact with neighboring components when the body of the motor vehicle vibrates, thereby preventing the possibility of fire due to breakage of an insulator coating of said harness.
