Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional deflector devices are made of resin with the upper body, mesh member, and lower body molded as a single unit, so that a new integral molding mold must be opened to adjust the height of the deflector device in the deployed state (i.e., to adjust the length of the mesh member), which results in high manufacturing costs.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a low-cost deflector device that is easy to adjust in height, and a sunroof device including the same. [Means for solving the problem]

[0006] A deflector device according to one aspect of the present invention is used in a sunroof device for a vehicle and comprises an upper body extending along the vehicle width direction, and a pair of deflector arms extending along the rear of the vehicle from both ends of the upper body in the vehicle width direction, the pair of deflector arms rotating around their rear ends so that the upper body moves up and down, a lower body attached to the front housing of the sunroof device and extending along the vehicle width direction, and a mesh member molded integrally with the upper body but molded separately from the lower body, the lower edge of the mesh member being connected to the lower body by sewing or welding.

[0007] According to the above configuration, since the mesh member is molded integrally with the upper body and separately from the lower body, the length of the mesh member can be easily changed to adjust the height of the deflector device in the deployed state, and costs are low. In addition, since the lower edge of the mesh member is connected to the lower body by sewing or welding, the integrated upper body and mesh portion can be easily connected to the lower body.

[0008] In addition, in the present invention, it is preferable that a plurality of bosses are provided on the front housing, a plurality of holes are provided on the lower main body, and the lower main body is fixed to the front housing by inserting the plurality of bosses into the plurality of holes, respectively.

[0009] As a result, the lower body can be easily fixed to the front housing by inserting the plurality of bosses of the front housing into the plurality of holes, respectively.

[0010] In the present invention, the lower body is preferably made of a PET material, and the upper body and the mesh member are preferably made of a resin.

[0011] As a result, compared to the integrally molded upper body and mesh member, the lower body is made of a relatively soft material and can be well sewn or welded to the mesh member, making it easy to fix the lower body to the front housing.

[0012] In the present invention, preferably, the lower body is made up of a plurality of separate members.

[0013] In the present invention, the lower body is preferably of one-piece construction.

[0014] In the present invention, preferably, the lower body is attached to the front housing by a snap mechanism.

[0019] A deflector device provided in a sunroof device according to the present invention will be described below with reference to FIGS.

[0020] In this embodiment, a sunroof device 1 is provided on the roof of a vehicle. The sunroof device 1 includes a pair of guide rails 12 extending in the front-rear direction of the vehicle and provided on both side edges of a roof opening 10 in the vehicle width direction, the pair of guide rails 12 being provided opposite each other in the vehicle width direction, a front housing 13 extending in the vehicle width direction and connecting the front ends of the pair of guide rails 12, a movable panel 11, and a deflector device 2.

[0021] A guide member (not shown) supporting the movable panel 11 moves rearward in the fore-and-aft direction of the vehicle (hereinafter simply referred to as "rearward") along a pair of guide rails 12, causing the movable panel 11 to move rearward, exposing the roof opening 10 and opening the sunroof device 1.

[0022] The deflector device 2 includes an upper body 20, a pair of deflector arms 21, a lower body 22, and a mesh member 23.

[0023] The upper body 20 extends along the vehicle width direction, and the pair of deflector arms 21 extend along the rear of the vehicle from both ends of the upper body 20 in the vehicle width direction, and the pair of deflector arms 21 rotate about their rear ends, causing the upper body 20 to move up and down. More specifically, the rear ends of the pair of deflector arms 21 are pivotally supported on the front ends of the pair of guide rails 12 via shafts 26 extending in the vehicle width direction, so that the rear ends of the pair of deflector arms 21 are pivotally supported on the pair of guide rails 12, respectively.

[0024] The upper body 20 moves up and down in accordance with the rotation of the pair of deflector arms 21. When the sunroof device 1 is closed, the upper body 20 is in the storage position and is stored below the movable panel 11. When the movable panel 11 moves rearward and the sunroof device 1 opens, the deflector arms 21 rotate due to the bias of an elastic biasing member (not shown), and the upper body 20 moves to the deployed position.

[0025] The lower body 22 is attached to the front housing 13 of the sunroof device 1 and extends along the vehicle width direction. More specifically, the lower body 22 is attached and fixed to the front housing 13.

[0026] In this embodiment, the mesh member 23 is molded integrally with the upper main body 20 and molded separately from the lower main body 22. More specifically, in this embodiment, the mesh member 23 and the upper main body 20 are an integrally molded body made of resin, the lower main body 22 is made of PET material (thermoplastic polyester), and a lower edge 231 of the mesh member 23 is sewn or welded to the lower main body 22, whereby the integrally molded body of the mesh member 23 and the upper main body 20 is connected to the lower main body 22.

[0027] Since the lower body 22 is made of PET material and the upper body 20 and mesh member 23 are made of resin, the lower body 22 is made of a relatively soft material compared to the integrally molded body of the upper body 20 and mesh member 23, and the lower body 22 made of PET material can be easily sewn or welded to the lower edge 231 of the mesh member 23.

[0028] The lower body 22 has an integral structure, and more specifically, the lower body 22 is plate-shaped extending in the vehicle width direction, and has a plurality of holes 30 formed therein; that is, the plate-shaped lower body 22 has a plurality of holes 30 formed therein that are aligned in the vehicle width direction and penetrate the body from top to bottom, and the number and arrangement of the holes 30 can be set according to actual needs and are not limited thereto.

[0029] A plurality of bosses 31 are provided on the front housing 13 corresponding to the holes 30. The plurality of bosses 31 are arranged, for example, in a line in the vehicle width direction, and the lower main body 22 is fixed to the front housing 13 by inserting the plurality of bosses 31 into the plurality of holes 30, respectively. Furthermore, by forming the holes 30 in the lower main body 22 made of PET material, the fixation between the lower main body 22 and the bosses 31 of the front housing 13 is more secure.

[0030] The operation of the deflector device will now be described.

[0031] As upper body 20 moves from the stored position to the deployed position, mesh member 23 deploys in a planar form between upper body 20 and lower body 22. Mesh member 23 has a width dimension that roughly corresponds to roof opening 10, and thereby rectifies the air blown into the vehicle interior through roof opening 10 from the front of the vehicle when sunroof device 1 is open, preventing air vibrations caused by wind being drawn into the vehicle interior.

[0032] When the sunroof device 1 is closed, the movable panel 11 moves forward, pushing the deflector arm 21 and rotating it downward, and accordingly the upper body 20 moves downward and the mesh member 23 is stored.

[0033] The deflector device 2 according to this embodiment can achieve the following technical effects.

[0034] (1) Because the mesh member 23 is integrally molded with the upper main body 20, the length of the mesh member 23 can be easily adjusted without considering the lower main body 22, and therefore the height of the deflector device 2 can be easily adjusted. In addition, there is no need to open a new mold for a three-component integrally molded body according to the mesh member 23 of each length, and only one mold is required, and the height of the deflector device can be easily adjusted by adjusting the length of the mesh member 23 by designing this mold, or by further processing the molded mesh member 23, such as by cutting, to adjust the length of the mesh member 23.

[0035] (2) The lower body 22 is made of PET material, and therefore can be easily sewn or welded to the mesh member 23.

[0036] (3) The lower body 22 can be easily attached to and detached from the front housing 13 by inserting the multiple bosses 31 provided on the front housing 13 into or pulling out the holes 30 formed in the lower body 22 made of PET material. In addition, because the lower body 22 is made of PET material, the engagement between the holes 30 of the lower body 22 and the bosses 31 of the front housing 13 is relatively strong.

[0037] Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications are possible without departing from the gist of the present invention.

[0038] In the above embodiment, the lower body 22 has an integral structure, but the present invention is not limited to this. The lower body 22 may be composed of multiple separate members, and by providing holes 30 in each separate member, it is possible to achieve the same effect as in the above embodiment.

[0039] In the above embodiment, an insertion / removal fixing structure between the hole 30 of the lower main body 22 and the boss 31 of the front housing 13 is described, but the attachment form between the lower main body 22 and the front housing 13 is not limited to this, and the lower main body 22 may be attached to the front housing 13 in a snap-type manner.

[0040] Although the present invention has been described above with reference to specific embodiments, the present invention is not limited to these specific embodiments. Designs that can be obtained by those skilled in the art by making appropriate design modifications to the specific embodiments will fall within the scope of the claims of the present invention as long as they incorporate the features of the present invention.
