【Technical field】
The present invention relates to a mounting structure of a wire type window regulator for opening and closing a window glass provided in a window opening of a vehicle back door window, a vehicle rear window (back panel), a side door, or the like. In particular, the present invention relates to a mounting structure of a wire-type window regulator that is more suitable for a window opening at a rear portion of a vehicle such as a back door window, a window at the rear of the vehicle, and the like.
[0002]
[Prior art and its problems]
A wire-type window regulator for a back door or a window at the rear of a vehicle usually has a pair of left and right guide rails in order to stably guide a wide window glass. A drive unit bracket is fixed to one of the left and right guide rails, and drive wires from the forward / reverse winding drive unit supported by the drive unit bracket are connected to wire guide members located above and below each guide rail. Through to the windowpane.
[0003]
In this wire type window regulator for a back door or a window at the rear of a vehicle, the distance between a pair of left and right guide rails is large, and one end of a drive unit bracket is fixed to one of the guide rails. Unless the rigidity of the bracket itself is increased, it is difficult to stabilize the position of the forward / reverse winding drive unit. For this reason, conventionally, a thick and heavy bracket had to be used as the drive unit bracket. However, no matter how thick the drive unit bracket is, the drive unit bracket is fixed to the guide rail in a cantilever manner, so that the sense of stability is poor. In addition, the position of the power supply harness with respect to the forward / reverse winding drive unit cannot be stabilized, and there is a possibility that the harness may interfere with the window glass that moves up and down. In conventional wire-type window regulators for back doors, the service holes formed in the vehicle mounting panel to improve the assembly workability are large, and the rigidity of the vehicle mounting panel itself for fixing the guide rail is low. It was difficult to stabilize the drive unit bracket or the power supply harness due to the mounting panel.
