  • Sliding door wire harness routing structure
    Patent number: 9150168
    Abstract: A wire harness (5) to be bridged between a slide door (3) and a vehicle body (BO) is inserted into a harness guide (6). The harness guide (6) is coupled by a multitude of stepped links (10). Each link (10) is composed of a first coupling portion (11) and a second coupling portion (12) connected to the first coupling portion (11) via a step. Coupling pins (23) projecting in a vertical direction on the second coupling portions (12) are rotatably inserted into insertion holes (14) in the first coupling portions (11) of adjacent stepped links (10), whereby the entire harness guide (6) has a uniform inclination and the wire harness (5) inside is also arranged in a similar inclined posture. Thus, if the harness guide (6) is curved when opening or closing the slide door (3), the wire harness (5) also is curved, but simultaneously twisted, relieving stress.
