Publication number: 20130126233Abstract: A wire harness cable routing structure includes a wire harness; an outer sheathing member sheathing the wire harness; an attachment member attachable to the vehicle body, a first end of the outer sheathing member fixed to the attachment member; and an accommodator installed within the door and accommodating the wire harness extending out from a second end of the outer sheathing member such that a surplus length of the wire harness can be absorbed by bending between a first route and a second route, the second route expanded so as to separate from the first route. An accommodating mouth allowing the wire harness to be inserted into the accommodator, and an extraction mouth allowing the accommodated wire harness to be extracted, are installed in the door and occupy a positional relationship offset in an interior-exterior direction of the door.Type: ApplicationFiled: June 10, 2011Publication date: May 23, 2013Applicant: SUMITOMO WIRING SYSTEMS, LTD.Inventors: Daiki Nagayasu, Tsutomu Sakata

Patent number: 8231168Abstract: In an arranging structure of a wire harness for a door, the wire harness is spanned between a door of a motor vehicle and a vehicle body at an indoor side inside of a weather strip. The wire harness is drawn out from a space between a door inner panel and a door trim at the door side and is provided with an excess length portion that follows opening and closing operations of the door. The excess length portion is drawn out from the space when the door is opened. The excess length portion is drawn along an arcuate outer periphery of a speaker disposed in the space to be contained in the space when the door is closed.Type: GrantFiled: July 2, 2007Date of Patent: July 31, 2012Assignee: Sumitomo Wiring Sytems, Ltd.Inventors: Morihiko Toyozumi, Isao Tsuji, Daiki Nagayasu, Tsutomu Sakata, Tetsuya Fujita, Sung-Jin Kim

Patent number: 8134076Abstract: A grommet includes a small tubular section, an enlarging tubular section continued from an end of the smaller tubular section, and an annular recess on an outer surface at a large diameter end of the enlarging tubular section. The small tubular section is inserted into a through-hole from one side of a vehicle body panel so that the annular recess engages the vehicle body panel. Stepped projections extend axially from the small tubular section to the annular recess . Each stepped projection has an angle rib that protrudes from a connecting end of the small tubular section to a position where the angle rib contacts a peripheral edge around the through-hole. Slopes of the angle ribs at upper positions contact a peripheral edge around the through-hole at a position where the slopes at the upper positions do not pass the annular recess.Type: GrantFiled: October 11, 2007Date of Patent: March 13, 2012Assignee: Sumitomo Wiring Systems, LtdInventor: Daiki Nagayasu

Patent number: 8091949Abstract: In an arrangement structure for a door wire harness, the door wire harness is arranged in a door of a vehicle body and is spanned in a space between the door and the vehicle body inside a vehicle room beyond a weather strip. The door wire harness is drawn out of a space between a door inner panel and a door trim at a door side and is fixed on the door at a wire harness drawing-out position. A door side fixing position of the door wire harness is shifted from a vehicle body side fixing position of the door wire harness in a vertical direction. A spanning section of the door wire harness between the door side fixing position and the vehicle body side fixing position is sheathed by a grommet having a flexible bellows-like tube portion and made of rubber or resin. The spanning section of the door wire harness is bent in an S-shaped configuration in a space between opposed surfaces of the door and the vehicle body when the door is closed.Type: GrantFiled: May 27, 2008Date of Patent: January 10, 2012Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Morihiro Toyozumi, Takashi Suzuki, Tetsuya Fujita, Isao Tsuji, Tsutomu Sakata, Daiki Nagayasu

Publication number: 20110265286Abstract: A grommet includes two semicircular closing plate sections that protrude from inner peripheries of a larger diameter end of an enlarging diameter tubular section provided with a vehicle body latch recess. Two half ring sections protrude from peripheral edges of central circular cut-outs at opposed ends of the semicircular closing plate sections. Adhesive tape is wound around the half ring sections. The semicircular closing plate sections are thinner than the enlarging diameter tubular section and have bellows-like configurations with projections and depressions. The half ring sections deform in accordance with an outer diameter of the wire harness and a bending direction of the wire harness. Deformation of the semicircular closing plate sections is absorbed by the bellows-like configurations, and the vehicle body latch recess of the enlarging diameter tubular section coupled to an outer periphery of the semicircular closing plate sections.Type: ApplicationFiled: December 17, 2008Publication date: November 3, 2011Applicant: SUMITOMO WIRING SYSTEMS, LTD.Inventors: Kinryu Paku, Tsutomu Sakata, Daiki Nagayasu, Masahide Tsuru

Patent number: 8020920Abstract: A wire harness for a door is spanned between a door inner panel of a motor vehicle and a vehicle body and is arranged near an indoor side over a weather strip. An outer protective assembly includes a flange outward fitting portion that is mounted on an outer surface of a flange projecting from a door facing surface of the vehicle body and that defines a wire harness threading space for passing the wire harness. The wire harness that passes through the wire harness threading space in the flange outward fitting portion can be arranged in a vehicle body inner panel. The outer protective assembly includes an inner cover and an outer cover. The inner and outer covers are coupled to each other to define a flat space for juxtaposing electrical wires of the wire harness. The inner and outer covers are bent in a U-shaped configuration around the flange to define the flange outward fitting portion.Type: GrantFiled: October 30, 2007Date of Patent: September 20, 2011Assignee: Sumitomo Wiring Systems Ltd.Inventors: Morihiko Toyozumi, Isao Tsuji, Daiki Nagayasu, Tsutomu Sakata, Tetsuya Fujita, Sung-Jin Kim
