Description

  The present invention relates to a wire harness routing device for a slide seat, and more particularly, to improve a connection configuration between a slider for inserting and fixing a wire harness and a slide seat so as not to cause a step on a vehicle floor. .

  A vehicle seat is equipped with various electrical components such as an electric reclining device and a seat heater. In order to supply power to these electrical components, a power supply wire harness is routed from the vehicle body floor to the seat. In the case of a slide sheet, it is necessary to cause the wire harness to follow the sliding motion of the sheet. For this reason, the wire harness is provided with an extra length portion.

  As this type of slide seat wire harness routing device, for example, as shown in FIG. 8, a harness rail 102 is installed along the side surface of the seat rail 101 installed on the lower surface side of the carpet material 150 serving as a vehicle compartment floor material. Then, an extra length absorbing case (not shown) is installed on the side of the harness rail 102, and a slider 103 for inserting and fixing the wire harness is slidably fitted to the harness rail 102, and the slider 103 is moved upward. There is provided a device that protrudes into the slide sheet 100 and is fixed to the slide sheet 100. In this apparatus, the slider 103 is made to follow the movement of the slide sheet 100, and the extra length is absorbed by the wire harness that is inserted from the harness rail 102 to the extra length absorption case through the slider 103 in accordance with the movement of the slide sheet. .

  The seat rail 101 is installed in the lower part of the passenger compartment floor through an opening provided in the carpet material 150 as the passenger compartment floor material, and the upper surfaces of both side upper surfaces 101b and 101c sandwiching the opening 101a in the center of the upper surface of the seat rail 101 are respectively provided Seat moldings 161 and 162 are installed. The seat moldings 161 and 162 are provided with opening and closing protruding pieces 161a and 162a for opening and closing the opening 101a of the seat rail, and the opening and closing protruding pieces 161a when the seat leg portion 113 of the slide seat inserted through the opening 101a passes through the seat rail 101. 162a is opened and the opening 101a is closed after passing the seat leg 113.

  The harness rail 102 arranged along the seat rail 101 is also installed below the carpet material 150 of the passenger compartment floor material. Therefore, in order to connect the slider 103 to the slide seat 100, it is necessary to project the slider 103 upward through an opening provided in the passenger compartment flooring. Therefore, as shown in FIG. 8, the upper portion of the slider 103 is bent and positioned along the upper surface 101 b of the seat rail 101, and the protruding portion 103 u bent again upward from the bent portion 103 b is formed on the seat rail 101. When the slider 103 is positioned directly above the upper surface opening 101a, the slider 103 can be protruded from between the seat moldings 161 and 162. Therefore, it is not necessary to provide a separate molding for the slider.

  However, when the bent portion 103b of the slider 103 is placed on the upper surface 101b of the seat rail, the height of the seat moldings 161 and 162 arranged on the upper surface of the bent portion 103b is higher than the upper surface of the carpet material 150 on both sides. Get higher. As a result, a step S is generated on the surface of the passenger compartment flooring, which deteriorates the appearance and may cause the occupant to trip over the step.

  In Japanese Patent Laid-Open No. 2010-193599 proposed as this type of wire harness routing device, as shown in FIG. 9, between the seat rail 101 and the wire extra length housing case 110 for housing the wire harness W / H. The slider 103 fitted to the harness rail 102 to be arranged is protruded upward without being along the upper surface of the seat rail 101 and is connected to the slide seat. Therefore, the moldings 171 and 172 that open and close the sliding portion of the slider 103 need to be separately installed adjacent to the seat moldings 161 and 162 installed on the upper portion of the seat rail 101.

JP 2010-193599 A

  The apparatus of Patent Document 1 requires a pair of seat moldings 161 and 162 for seat rails and a pair of moldings 171 and 172 for sliders, and thus there is a problem that the cost is high and installation work is troublesome. . In FIG. 9, the seat moldings 161 and 162 and the slider moldings 171 and 172 are not considered to be the same height as the surface of the carpet material 150 on both sides, and a step is generated.

  This invention is made | formed in view of the said problem, and makes it the subject to make it not generate | occur | produce a level | step difference on the surface of a compartment flooring, without increasing the number of installation of a mall.

In order to solve the above-mentioned problems, the present invention provides a slider for installing a harness rail below a passenger compartment floor along the side surface of a seat rail of a slide seat of an automobile, inserting and fixing a wire harness, and connecting to the slide seat. In a wire harness routing device for a slide seat that is slidably fitted to the harness rail and causes the wire harness to follow the movement of the slide seat,
The upper part of the slider is protruded upward through an opening provided in the vehicle compartment floor material through an opening provided in the harness rail and fixed to the slide seat, and the vehicle compartment floor sandwiching the slider protrusion opening Among the materials, the floor on one side is a mall installed on the upper surface of the seat rail, the floor on the other side is a carpet, and the opening / closing piece projects from the seat rail upper surface fixing portion of the mall. The opening / closing piece closes the upper surface of the slider projecting opening without contacting the slider, and connects the seat rail upper surface fixing portion and the upper surface of the carpet material on the other side with a flat surface. When the slider moves and contacts the opening / closing piece, the opening / closing piece is slid upward along the side surface of the slider to open the slider protruding opening. It provides a harness device.

  As described above, the upper portion of the slider protrudes upward through the slider protrusion opening provided in the passenger compartment floor material without passing through the upper surface of the seat rail. In addition, the opening / closing portion projects from a seat rail upper surface fixing portion of a molding used as a seat molding for seat rail via a thin hinge portion. As described above, when the thin hinge portion is provided, when the slider moves and contacts, the slider protrusion opening can be easily opened by turning upward with the thin hinge as a fulcrum along the side surface of the slider.

  As described above, in the present invention, since the slider is not placed along the upper surface of the seat rail, the upper surface position of the molding installed on the upper surface of the seat rail is not increased, and can be made the same height as the surfaces of the carpet materials on both sides. . And the seat molding installed in the upper surface of one side (harness rail side) of a seat rail is provided with opening and closing pieces on the left and right sides of the seat rail upper surface fixing portion. One open / close piece is used for opening and closing the opening of the seat rail as in the conventional case, and the other is used as an open / close piece for the slider protrusion opening of the harness rail for projecting the slider. That is, the opening and closing of the slider projecting opening is a one-side opening performed from one side by one opening and closing piece provided in the seat molding. With this configuration, the slider protrusion opening can be opened and closed using one side of a pair of seat rails for seat rail that has been installed conventionally, and a dedicated molding for opening and closing the slider protrusion opening is unnecessary. It is possible to reduce the parts cost and the installation work cost.

A surplus length storage case is continuously installed on the side surface or front surface of the harness rail, and the wire harness inserted and fixed to the slider sliding in the harness rail is inserted around the surplus length storage case to the outside. It is preferable to connect with a floor harness routed along the drawer and the floor panel.
Instead of installing the extra length accommodation case, the wire harness may be drawn downward from the slider, and the drawn electric wire extra length may be loosened in the space below the floor and connected to the floor harness.

  The harness rail includes a harness insertion portion having a box-shaped cross section that extends along the outer surface of the side wall of the seat rail, and a slider sliding portion that projects and communicates with one side of the upper surface of the harness insertion portion, The upper surface opening of the slider sliding portion is exposed to the opening of the passenger compartment floor material, the upward projecting portion of the slider protrudes from the opening, and the slider is connected to the lower surface or side surface of the seat frame of the slide seat. .

  The carpet material used as the passenger compartment floor material is a composite structure in which a floor carpet is laid on a body panel made of a rigid plate via a carpet base material such as an elastic mat. There is a space between the carpet material and a floor panel made of a metal plate on the lowermost surface of the vehicle, and the space is filled with vibration absorbing material, heat insulating material, sound insulating material, etc., and vibration and noise transmitted from below to the passenger compartment It absorbs heat and keeps the passenger compartment in a comfortable space. An opening is provided in the carpet material at a location corresponding to the seat rail and harness rail installation portion disposed adjacent to each other, and the seat rail and the harness rail are installed below the passenger compartment floor through the opening. The mall is installed on the upper surface of the rail as described above. Opening and closing the opening that exposes the seat rail and harness rail with the opening and closing piece provided in the molding, opens the opening when the seat leg and slider move, and closes the opening after movement to prevent intrusion of dust and foreign matter In addition, we are trying to improve the appearance.

  As described above, the wire harness routing structure for a slide seat according to the present invention includes a slider that is slidably fitted to a harness rail installed at a lower portion of the passenger compartment floor along the side surface of the passenger compartment floor. By projecting upward from the material and connecting to the slide sheet, and opening and closing the slider projecting opening with an opening / closing piece provided on the other side of the sheet molding, it is not necessary to install a molding dedicated to the slider. In addition, since the height of the surface of the molding is the same as the height of the adjacent carpet material, it is possible to prevent the occurrence of steps.
