Description

  The present invention relates to a support structure for a harness connected to a power feeding terminal of a heating wire provided on a lifting glass of a sliding window provided in a vehicle.

Of the window glass provided in the vehicle, harnesses such as a heating wire for removing cloudiness and a power supply cable for a wiper motor may be routed on the rear glass provided at the rear. In this case, depending on the vehicle model, there is one in which the rear glass can be opened and closed in a hatch shape (for example, see Patent Document 1). The harness is routed through an arc-shaped tube that is provided between the rear glass and the vehicle body and that slides and expands corresponding to the rotation trajectory of the rear glass. The harness uses curl cords.
JP 2000-232717 A

  However, when the rear glass is slid open and closed, it is not preferable to use a curl cord because the amount of movement of the contact point to which the harness is connected is large. Therefore, if the harness is routed without using the curl cord, the harness must be loosened by a length corresponding to the amount of movement of the rear glass, and the periphery of the rear glass becomes complicated. Also, if you try to route the harness so that it does not sag in the vicinity of the rear glass, it is supported at a position far from the rear glass, and the change in the required length of the harness that changes as the rear glass moves is reduced. There is a need. However, in order to support the harness at a position away from the rear glass, the vehicle body around the rear glass must have a margin.

  Then, an object of this invention is to provide the support structure of the harness which supports a harness in the vicinity of raising / lowering glass, and the periphery of raising / lowering glass does not become complicated by the routed harness.

The harness support structure according to the present invention includes a harness, a bracket, and a flexible member. Harness end is connected to the power supply terminal of the heating wire provided in lifting the glass being drawn along the vehicle body from a closed state to close the window portion of the vehicle to an open state to open the window of the vehicle. The bracket is closer to the position of the end of the harness when the elevating glass is in the process of moving than the position of the end of the harness when the elevating glass is in the closed and open state from the end of the harness Fix to range. The flexible member has higher bending rigidity than the harness, the base portion is fixed to the vehicle body side , the distal end portion is a free end separated from the peripheral member, and the intermediate portion from the end portion of the harness to the first fixing portion. Support at least at the tip.

In this case, the flexible member is preferably formed in a cylindrical shape that is extrapolated to the harness, the base end is fixed to the bracket, and extends from the base portion toward the power feeding terminal of the elevating glass in the closed state. Alternatively, the flexible member may be a coil spring that is extrapolated to the harness. And a bracket is fixed to the rail which guides raising / lowering glass. Also, when the elevating glass moves from the closed state to the open state, only the harness is deformed within the reach of the harness closer to the power supply terminal than the tip, and only the harness closer to the power supply terminal is bent than the tip. Then, when the length becomes insufficient, the flexible member starts to bend as a whole.

  According to the harness support structure of the present invention, the harness is supported midway by a flexible member having higher bending rigidity than the harness. The flexural rigidity is different between the harness-only portion and the portion supported by the flexible member while the elevating glass moves from the closed state to the open state. Thereby, since it can prevent that a harness hangs down, the circumference | surroundings of raising / lowering glass do not become complicated.

  In addition, when the flexible member is formed in a cylindrical shape that is extrapolated to the harness, or is a coil spring that is extrapolated to the harness, the shape of the support structure of the harness is simple and does not take up space. . Further, in addition to the above-described shape of the support structure of the harness, the harness is fixed to a bracket provided on a rail for guiding the elevating glass. As a result, the wiring of the harness can be further simplified.

  The support structure of the harness 1 according to one embodiment of the present invention will be described with reference to FIGS. 1 to 3 by taking as an example a case where the support structure is applied to a rear glass window 10 with an elevator function. The left and right edges 20a and 20b of the elevating glass 20 of the rear glass window 10 are mounted on rails 21a and 21b arranged in the vertical direction. A regulator 23 for moving the elevating glass 20 is attached to the lower edge 20 c of the elevating glass 20. The elevating glass 20 moves up from the closed state P1 where the rear glass window 10 is closed to the open state P2 where the rear glass window 10 is opened. In the open state P2, the elevating glass 20 is in a state of being drawn into the vehicle body.

  The heating glass 24 is wired on the elevating glass 20 to prevent clouding. The feeding terminal 25 of the heating wire 24 is provided on the lower edge 20 c of the elevating glass 20. The support structure of the harness 1 according to the present invention is applied to the support structure of the harness 1 connected to the power supply terminal 25 of the heating wire 24.

  The support structure for the harness 1 includes a harness 1, a bracket 2, and a flexible member 3. The end 1a of the harness 1 is attached to the power supply terminal 25 so that the harness 1 extends upward. The bracket 2 is positioned at the end 1a of the harness 1 when the elevating glass 20 is in the middle of movement than the positions A and B of the end 1a of the harness 1 when the elevating glass 20 is in the closed state P1 and the open state P2. Range close to C, specifically, the position (top dead center) A of the feeding terminal 25 of the elevating glass 20 in the closed state P1 and the position (bottom dead center) of the feeding terminal 25 of the elevating glass 20 in the open state P2. It is attached to the rail 21a at a position close to position C, which is exactly in the middle of B. The bracket 2 supports the first fixing portion 1 b from the end portion 1 a of the harness 1.

  The flexible member 3 has higher bending rigidity than the harness 1, and the base 3a is fixed to the bracket 2 provided on the rail 21a. The flexible member 3 is formed in a cylindrical shape extending to the power supply terminal 25 side of the elevating glass 20 in the closed state P1. In the present embodiment, a coil spring that is extrapolated to the harness 1 as shown in FIG. The harness 1 is passed through the flexible member 3. As shown in FIG. 2, the base portion 3 a of the flexible member 3 is fixed to the bracket 2 at a position closer to the end portion 1 a of the harness 1 than the first fixing portion 1 b of the harness 1.

  In addition to the coil spring, the flexible member 3 may be a tube that is elastically deformed. Alternatively, a cantilever leaf spring in which the base portion is fixed to the vehicle body at a position away from the bracket 2 and the harness 1 is supported at the distal end portion may be used.

  Next, the harness 1 which deform | transforms when the raising / lowering glass 20 moves is demonstrated. FIG. 3 shows a state in which the base 3a of the flexible member 3 is fixed at a position away from the rail 21a for convenience of explanation. The harness 1 and the flexible member 3 are deformed as shown in FIG. 3 while the elevating glass 20 moves from the closed state P1 to the open state P2. When the elevating glass 20 is in the closed state P <b> 1, the harness 1 extends to the power supply terminal 25 as it is along the extending direction of the flexible member 3. During this time, the harness 1 is not so long and does not hang down.

  When the regulator 23 is operated and the elevating glass 20 is lowered toward the open state P <b> 2, the harness 1 is connected to the tip of the flexible member 3 until the harness 1 reaches the power supply terminal 25 only by deformation of the harness 1. It is deformed so as to be supported by 3b. If the elevating glass 20 is further lowered and the length of the harness 1 becomes insufficient only by bending at the distal end portion 3 b of the flexible member 3, the flexible member 3 starts to bend as a whole by being pulled by the harness 1. Conversely, when the elevating glass 20 returns from the open state P2 to the closed state P1, first, the flexible member 3 returns to its original shape, and then the harness 1 is deformed.

  Thus, while the elevating glass 20 moves, the harness 1 is not easily loosened. In particular, even when the distance from the power supply terminal 25 to the first fixing portion 1b of the harness 1 cannot be taken sufficiently with respect to the moving amount of the elevating glass 20, the flexible member 3 having higher bending rigidity than the harness 1 can be used. By supporting in two stages, the harness 1 is prevented from loosening.

  In addition, when an antenna is provided in the raising / lowering glass of the glass window with a raising / lowering function instead of the heating wire 24, the harness 1 is a signal connected to an antenna instead of the power supply cable connected to the heating wire 24. Any line can be used. Moreover, the support structure of the harness 1 may be a moving member that slides and requires power supply or cable connection instead of the elevating glass 20.
