Description

  The present invention relates to an electric wire routing device for routing electric wires across a support and a slide body.

  For example, in an automobile or the like, a slide sheet as a slide body is slidably provided on a vehicle body as a support body. Electronic devices such as a seating sensor for detecting whether or not an occupant is seated and a seatbelt sensor for detecting whether or not a seatbelt is worn are attached to the slide seat. For this reason, in order to connect the electronic device attached to the slide sheet and an electronic device such as a control device provided on the vehicle body side, the vehicle provided with the slide seat is connected between the vehicle body and the slide seat. Various electric wire arrangement apparatuses for arranging electric wires have been used (see, for example, Patent Document 1).

  The wire routing device accommodates an electric wire connecting an electronic device attached to the slide sheet and an electronic device such as a control device provided on the vehicle body side, and an excess length portion of the electric wire disposed below the slide sheet. The case includes a case, a rail provided inside the case, and a protector (sliding member) that is slidably supported by the case and the rail and guides the electric wire that passes through the inside from the case to the slide seat side. The case is formed in a box shape extending in the sliding direction of the slide sheet, and this case is provided with a surplus length accommodating portion that accommodates the surplus length portion of the electric wire bent in a U shape. In addition, an opening that extends in the sliding direction and through which the protector is inserted is formed in the upper part of the case.

  The protector includes a fixed portion that holds a part of the extra length accommodating portion of the electric wire, an electric wire accommodating portion that is connected to the fixed portion and formed in an L-shaped cylindrical shape, and is provided on the outer surface of the electric wire accommodating portion in the rail. And a sliding portion accommodated slidably. The protector slides in conjunction with the slide sheet by being pulled from the slide sheet via the bracket by a string or the like. This protector guides the electric wire gripped by the fixing portion to the inside of the electric wire housing portion and guides it to the slide sheet side.

  A pair of moldings is attached to the opening through which the protector is inserted. Each of these moldings is made of synthetic resin, and is formed with an elastically deformable covering piece that covers the opening of the case. In a position where the protector is not inserted between the pair of moldings, the cover pieces in the natural state contact each other to cover the opening, thereby preventing foreign matter from entering the case. On the other hand, at a position where the protector is inserted between the pair of moldings, each cover piece is elastically deformed by being pushed and spread by the protector, and the cover piece is in contact with the surface of the protector.

  However, in the conventional wire routing device as described in Patent Document 1, in order to reduce the frictional resistance when the cover piece provided in the pair of moldings and the protector (slide member) are in sliding contact with each other, In addition to forming the cover piece from a soft material such as a soft resin, it is necessary to reduce the thickness of the cover piece to ensure the amount of elastic deformation. When an external force acts on the cover piece that can be elastically deformed in this way, the cover piece enters the inside from the opening of the case, and the cause that the covered cover piece impedes sliding of the slide member There was a possibility. Furthermore, when a foreign object enters the pair of malls so that the cover piece is pushed in from the outside, the cover piece does not have a repulsive force that resists this entry, and the foreign object can be sufficiently intruded. It was difficult to suppress.

  Therefore, an object of the present invention is to provide an electric wire routing device that can suppress the entry of foreign matter into the case without obstructing the sliding of the slide member.

In order to achieve the above object, the wire routing device according to claim 1 is a wire routing device for routing an electric wire across a support and a slide body, and one of the support and the slide body.

  According to the invention described in claim 1, the pair of moldings are provided with a gap between each other, and the first projecting piece is formed of a soft material. By appropriately setting the distance dimension, the sliding contact resistance with the slide member can be suppressed. Further, if the tip end edge of the second projecting piece is provided so as to recede from the tip end edge of the first projecting piece, if the second projecting piece is provided at an interval that does not contact the slide member, the slide member The slides are not disturbed. Further, since the second projecting piece is formed of a material harder than the first projecting piece, even when an external force is applied to the first projecting piece, the second projecting piece suppresses deformation of the first projecting piece. Thus, the first protruding piece can be prevented from entering the inner side of the case.

In addition , since the intermediate portion formed to be thicker than the base end portion and the tip end portion of the first projecting piece is provided so as to overlap the second projecting piece, the first projecting piece is inward of the case.

By reducing the thickness of the first projecting piece in this manner, the sliding contact resistance with the slide member with which the first projecting piece comes into sliding contact can be reduced, and the sliding of the slide member can be smoothed.

Furthermore , since the intermediate portion is formed convex toward the second projecting piece, and the portion having the maximum thickness is provided near the base end portion of the first projecting piece, the first projecting piece is directed inward of the case. When deformed, the intermediate portion can be easily brought into contact with the second projecting piece, and the intermediate portion can be brought into contact with the second projecting piece even with a small amount of deformation. Therefore, it is possible to reliably prevent the first protruding piece from entering the case and to prevent foreign matter from entering the case more reliably.

  According to the invention described in claim 4, since the inclined surface is formed at the tip of the second projecting piece, when the foreign matter that has entered the case is discharged, the foreign matter is removed between the second projecting pieces. The inclined surface can be guided toward the gap, and the guided foreign matter can be easily discharged out of the case through the first protruding pieces.

According to the invention described in claim 2, extending portions extending inwardly of the case than the second protrusion has a large gap dimension than the second protrusion, the distal end portion of the extending portion Since the slanted surface is formed in the case, foreign matter that has entered the case can be guided between the extended portions, and the guided foreign matter can be guided between the second projecting pieces and between the first projecting pieces and outside the case. Can be discharged easily.

According to the invention described in claim 5 , the second protrusion retreat distance is set to 1/2 or less with respect to the length dimension of the first protrusion in the protruding direction. Since the second projecting piece is provided over half or more of the base end side, the deformation of the first projecting piece toward the inner side of the case can be reliably suppressed by the second projecting piece.
