Description

  The present invention relates to a vehicle harness support structure.

Conventionally, an air conditioner for a vehicle has been generally arranged in front of a passenger seat.
For example, Patent Document 1 discloses a configuration in which a blower unit, a cooler unit, and a heater unit constituting an air conditioner are arranged side by side in the vehicle width direction in front of a passenger seat.

JP-A-8-142708

  However, the layout of such an air conditioner results in a narrower passenger's foot space. In recent designs, the air conditioner is installed inside the instrument panel to secure a wider passenger's foot space. It is often arranged in the center of the direction.

  However, when the air conditioner is placed in the center in the vehicle width direction, the placement space of other equipment, etc. that has been housed inside the instrument panel will be compressed. One of the elements to be done is a harness extending in the vehicle width direction inside the instrument panel.

  By the way, generally, an instrument panel support member extending in the vehicle width direction is attached to the front part of the vehicle, and the instrument panel is supported by the instrument panel support member. When arranged in front of the seat, for example, the harness is arranged to extend along the instrument panel support member in front of the instrument panel support member (in the vehicle front-rear direction).

  When the air conditioner was placed in front of the passenger seat, the space in the center in the vehicle width direction inside the instrument panel, particularly the space in the vehicle front-rear direction (depth), had a relatively large margin. There was no problem even if the harness was arranged in front of the instrument panel support member (in the vehicle longitudinal direction).

  However, when the air conditioner is arranged at the center in the vehicle width direction inside the instrument panel, the depth inside the instrument panel is entirely occupied by the air conditioner, so the air conditioner and the instrument panel support member The layout of the harness has become very important. That is, depending on the arrangement of the harness, the space (depth) of the instrument panel in the vehicle front-rear direction will be enlarged, but this enlarged depth of the instrument panel will reduce the indoor living space. There's a problem.

  In recent years, since electronic devices and electric devices mounted on vehicles are increasing, the diameter of a harness for supplying power to these devices is also increasing. Since the increase in the diameter of the harness directly leads to an increase in the weight of the harness, when such a heavy harness is placed on the defroster duct of an air conditioner or a duct for air conditioning in a vehicle, these ducts are connected to the harness. It may be deformed by the weight.

  Accordingly, the present invention has been invented to solve the above-described problems, and can increase the depth of the instrument panel or deform the duct of the air conditioner disposed inside the instrument panel. It is an object to provide a vehicle harness support structure and a harness mounting method that can support a harness.
