Abstract
Abstract A wiring arrangement for an automotive vehicle equipped with a hot-wire-type defroster (2) and a radio antenna (1) on a rear windshield (3), a defroster sensor (8) and several electrical devices such as lamps, motors, speakers (11R, 11L), an air cleaner (13) and the like, comprises a first cable (30) connected to the defroster (2) and the sensor (8), a second cable (31) connected to the electrical devices, and a plurality of noise preventive filter elements (32R, 32L, 7). The first cable (30) and the second cable (31) are isolated from one another in a space in the rear of a rear seat back panel and assembled together in the space in front of the rear seat back panel. The first cable (30) is provided with said noise preventive filter elements. In this manner, noise signals generated by the electrical devices are prevented from being picked up by the radio antenna (1).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
Electrical wiring arrangement for use in an automotive vehicle equipped with a hot-wire-type rear defroster and a radio antenna on a rear windshield, a defroster sensor for controlling said defroster, and electrical devices, characterized by a first cable (30,29R,29L,25,5R,5L) connected to the defroster (2) and the defroster sensor (8), a second cable (31 ...) connected to the electrical devices (11R, 11L,12,13 ...), said second cable (31 ...) being isolated from said first cable (30 ...) in at least the space in the rear of a rear seat back panel (34) and being bundled with said first cable in the space in front of the rear seat back panel (34), and a plurality of noise preventive filter elements (32R,32L,7), said elements being interposed in said first cable (30 ...), thereby preventing the radio antenna (1) from intercepting noise generated by the electrical devices.
Claim 2
Dependent Claim
142 words
Electrical wiring arrangement for use in an automotive vehicle equipped with a hot-wire-type rear defroster and a radio antenna on a rear windshield, a defroster sensor for controlling said defroster, and electrical devices, characterized by a first cable (30,29R,29L,25,5R,5L) connected to the defroster (2) and the defroster sensor (8), a second cable (31 ...) connected to the electrical devices (11R, 11L,12,13 ...), said second cable (31 ...) being isolated from said first cable (30 ...) in at least the space in the rear of a rear seat back panel (34) and being bundled with said first cable in the space in front of the rear seat back panel (34), and a plurality of noise preventive filter elements (32R,32L,7), said elements being interposed in said first cable (30 ...), thereby preventing the radio antenna (1) from intercepting noise generated by the electrical devices.
Claim 3
Dependent Claim
59 words
Wiring arrangement as set forth in claim 1, characterized in that in the space in the rear of the rear seat back panel (34) said first cable (30 ...) is arranged in the space above a rear parcel tray panel (6) and said second cable (31 ...) is arranged in the space beneath the rear parcel tray panel (6).
