Description

[Detailed description of the invention] This invention is a wind deflector that prevents air from flowing into and out of the interior of a car when the car is driven with the sunroof installed on the roof panel open. This relates to the mounting structure.

Recently, automobiles have been manufactured in which an opening is formed in the roof panel of an automobile, and a sunroof made of a transparent or opaque material is attached to the opening so that it can be opened and closed or detached. In this type of car, when the sunroof is opened or removed to leave the opening open, outside air flows in from the front edge of the opening, or indoor air is sucked out, causing the indoor air to vibrate. To prevent this, a wind deflector is provided at the front edge of the opening. This wind deflector is configured to be raised up when the vehicle is running with the vehicle open, and laid down and accommodated within the sunroof when the vehicle is closed.

By the way, since the above-mentioned wind deflector is raised when the sunroof is opened, it is necessary to install the sunroof and the wind deflector as disclosed in, for example, Japanese Utility Model Application Publication No. 56-157117. are done separately. The installation of a conventional wind deflector is
As shown in the figure, a undulation mechanism 5 is provided at two locations in the vehicle width direction on the front edge 3 of an opening 2 formed in a roof panel 1 of the vehicle body, and is biased with an elastic force in the rising direction by a spring 4. A wind deflector 6 is attached to the undulating mechanism 5, and a hinge case 8 is fixed to the vertical wall 7 of the front edge 3 of the roof panel 1, and a hinge case 8 is attached to the front end of the sunroof 9. The arcuate end portion 11 is inserted into the hinge case 8 to attach the sunroof 9 to the roof panel 1 so as to be openable and closable, and the wind deflector 6 is attached to the roof panel 1 by a presser plate 12 provided on the inner surface of the sunroof 9.
It is designed so that it can be held down.

As mentioned above, conventionally, the hinge 10 to which the sunroof 9 is attached, the hinge case 8, and the undulating mechanism 5 to which the wind deflector 6 is attached are each separately attached to the roof panel 1, which requires a large number of parts and a large number of assembly steps. Therefore, the assembly workability is poor, and a large installation space is required for both members 6 and 9, which restricts the interior space accordingly, and the strength of the front edge 3 of the roof panel 1 must be improved, which increases the number of parts. However, there was a problem of high costs.

This idea was made in view of the above-mentioned problems in installing the wind deflector provided at the front edge of the opening of the roof panel.The wind deflector is rotatably integrated into the hinge case that supports the hinge that attaches the sunroof to the vehicle body. The mounting portions of both components to the vehicle body are combined into one.

Although the wind deflector is generally installed over the entire width of the opening in the roof panel, it is also possible to install independent wind deflectors on the left and right sides of the opening.

A pivot pin is inserted across the mounting portion and the pivot boss portion to connect them, and one end of the spring wound around the pivot pin is locked to the hinge case, and the other end is locked to the wind deflector. Since the wind deflector is always biased with an elastic force in the rising direction, the wind deflector can be attached to the hinge case, eliminating the need for special mounting parts for attaching the wind deflector to the vehicle body, and reducing the number of parts. In addition, the number of assembly steps is reduced, and since the installation of the sunroof and the wind deflector can be combined into one, the installation space can be narrowed, and the interior space can be expanded accordingly. Furthermore, the wind deflector can be assembled into a unit by pre-assembling the hinge case to the hinge case, which simplifies the assembly work to the vehicle body and greatly improves work efficiency. Furthermore, since the hinge holder for supporting the sunroof was attached to the locking flange of the hinge case together with the wind deflector using a pivot pin, the cylindrical part of the hinge case inserted from the roof panel into the interior becomes a complete bag. Even if rainwater or the like infiltrates from the hinge holder into the cylindrical part of the hinge case, the rainwater or the like will not leak from the cylindrical part and enter the room, thereby improving waterproofness.
