  An automobile seal structure according to an embodiment of the present invention will be described with reference to FIGS. This is because, as shown in FIGS. 4 and 5, the roof weatherstrip 10 attached along the roof of the automobile is extended to the lower corner C of the rear triangular window to which the quarter glass 1 is fixed. The present invention relates to a seal structure of an automobile connected to a belt line weather strip 20 attached along a belt line BL. The roof weather strip 10 and the belt line weather strip 20 are both formed by extrusion molding, and are connected to each other at a sharp lower corner portion C by molding.

The roof weather strip 10 has a mounting base 11 and a frame 100 having a substantially U-shaped section 100a, and is integrally formed on the outside of the vehicle with the mounting base 11, and bulges inward to form an edge of the quarter glass 1. And a second hollow seal portion 13 which is integrally formed on the vehicle interior of the mounting base 11 and bulges toward the vehicle exterior to elastically contact the inside surface of the quarter glass 1. Note that, instead of the second hollow seal portion 13, a seal lip portion having a substantially tongue-like cross section may be elastically contacted with the inner side surface of the quarter glass 1.
The beltline weatherstrip 20 has the same cross-sectional shape as the roof weatherstrip 10.

  The quarter glass 1 is bolted and fixed to the side edge of the triangular window at the position of the division bar provided on the front side edge thereof. An adjusting device (glass adjuster) 5 capable of finely adjusting the position is provided. Although the adjusting device 5 is not particularly limited, here, a rotating type is used, and the quarter glass 1 is pushed out of the vehicle by forward rotation or reverse rotation, or the quarter glass 1 is pushed back to the inside of the vehicle. It has become.

A cover sealing material 50 is provided to cover the lower corner portion C of the quarter glass 1 from the inside of the vehicle so as to short-circuit around the lower corner portion C and completely cover and hide the adjusting device 5 from the inside of the vehicle.
The cover sealing material 50 includes a main body 50A, upper and lower locking portions 50B and 50C provided on the back surface side (rear side of the automobile) of the main body 50A, and a plurality of protrusions 50D, 50E and 50F.
As shown in FIG. 3, the main body 50A has a shape in which an upper end 51 and a lower end 52 are curved in a bow shape (arc shape) toward the front of the vehicle with respect to the central portion 50T. As shown in FIG. 3, the cross-sectional shape of the upper end 51 is tapered (thinner) toward the upper end, and the cross-sectional shape of the lower end 52 is also tapered toward the lower end. It is tapered (thin) (not shown).
As shown in FIG. 2, the cross-sectional shape of the main body 50 </ b> A is substantially crescent-shaped, and the inner side surface 53 and the outer side surface 54 are curved so as to approach the central portion 50 </ b> T toward the rear of the vehicle. ing.

The locking portion 50B provided on the upper portion of the cover sealing material 50 protrudes upward and fits into a groove 100b formed in the frame 100 to which the roof weather strip 10 is attached as shown in FIG. Have been combined.
Conversely, the locking portion 50C provided at the lower portion of the cover sealing material 50 protrudes downward, and is formed on the frame 100 to which the belt line weather strip 20 is attached as shown in FIG. It is hooked on the projection 100c. The protruding portion 100c is formed in a round shape, and when the lower end of the locking portion 50C is pushed into the rear of the vehicle, the protruding portion 100c smoothly falls from the top to the lower portion and is hooked on the protruding portion 100c.
As described above, the cover seal member 50 can be easily removed because the locking portions 50B and 50C are merely fitted into the frame 100, and the adjustment of the adjusting device 5 can be easily performed. .

The plurality of projections 50D, 50E, and 50F formed on the cover sealing material 50 are ribs extending vertically in this order from the inside of the vehicle. When the cover sealing material 50 is attached, the projections 50D and the ends of the projections 50E are formed. The portion is in contact with the second hollow seal portion 13 of the roof weather strip 10 and the belt line weather strip 20. The protrusion 50F has a larger protrusion amount than the protrusions 50D and 50E, and is inserted between the interior material 2 and the roof weather strip 10 and between the interior material 2 and the belt line weather strip 20.
The outermost projection 50D is formed on the inner side of the outer side surface 54 of the cover sealing material 50, and the innermost projection 50F is formed on the outer side of the inner side surface 53 of the cover sealing material 50. And is in contact with panel 110 of body 300 from outside the vehicle.

When the cover sealing material 50 is attached, the vehicle inner side surface 53 elastically contacts the interior material 2, and the vehicle outer side surface 54 elastically contacts the inner surface of the quarter glass 1.
As a result, the adjusting device 5 provided inside the quarter glass 1 on the inside of the vehicle is mounted in the space surrounded by the protrusion 50D of the cover sealing material 50, the vehicle outside side surface 54, and the second hollow seal portion 13 of the roof weather strip 10. It is not exposed because it is stored. Note that a cover design material (for example, a colored sheet material or the like) is disposed at the position of the quarter glass 1 facing the adjustment device 5 to cover the adjustment device 5 from the outside of the vehicle, and is not visible from the outside of the vehicle through the quarter glass 1. Absent.

  The cover sealing material 50 is made of a thermoplastic elastomer having a JIS-A hardness of 90 degrees or less, and the JIS-A hardness of the upper end 51 and the lower end 52 is smaller than the JIS-A hardness of the central portion 50T. And an integrated product. Here, the outer side surface 54 and the inner side surface 53 are also preferably made of the same material as the upper end 51 and the lower end 52, and the upper end 51 and the lower end 52 of the cover sealing material 50, and further, the outer side surface 54 and the inner side The hardness of the side surface 53 is preferably JIS-A hardness 85 degrees or less. Due to the rigidity due to the hardness and the warped state of the main body 50A of the cover sealing material 50, the upper end 51 elastically contacts the roof weather strip 10 without biting, and the lower end 52 also elastically contacts the belt line weather strip 20 without biting. I try to touch. In particular, if it is a thermoplastic elastomer having a JIS-A hardness of 75 to 85, it can be formed of the same material without dividing the central portion and the other upper end 51, lower end 52, outer side surface 54, and inner side surface 53.

  Here, examples of the thermoplastic elastomer (TPE) include olefin-based TPO and styrene-based TPS, but are not limited thereto.

The roof weather strip 10 is made of rubber mainly composed of EPDM, and is formed of a solid material, a sponge material, or both.
In the present embodiment, the first hollow seal portion 12 and the second hollow seal portion 13 are formed of a flexible sponge material in consideration of the sealing property to the quarter glass 1. Further, of the plurality of protrusions 50D, 50E, 50F formed on the cover seal material 50, the surface of the second hollow seal portion 13 where the center protrusion 50E contacts is thinned by a soft sponge material. It has at least a two-layer structure in which a thick flexible layer and a high-rigidity portion formed of a material having a higher hardness than the surface (for example, a solid material or a sponge material having a low foaming degree) are superposed therein. This prevents unnecessary intrusion into the roof weather strip 10 by the cover sealing material 50. (Not shown)
The position in the cross-sectional shape of the second hollow seal portion 13 where the central projection 50E contacts is also the position where the upper end 51 and the lower end 52 of the cover sealing material 50 elastically contact. Unnecessary digging is also prevented.
The belt line weather strip 20 has the same structure as the roof weather strip 10 described above.

According to the seal structure of the automobile configured as described above, the roof weather strip 10 extends to the lower corner C of the rear triangular window to which the quarter glass 1 is fixed, and is connected to the belt line weather strip 20. Since the lower corner portion C of the quarter glass 1 is short-circuited between the quarter glass 1 and the interior material 2 and the cover sealing material 50 that covers the inside of the vehicle is provided, the quarter glass 1 The adjusting device 5 provided inside the vehicle can be securely covered without being exposed.
At this time, the cover sealing material 50 is made of a synthetic resin (more specifically, a thermoplastic elastomer), and its upper end 51 is tapered in a cross-sectional shape so as to be elastically contacted with the roof weather strip 10 without biting. The lower end 52 also has a tapered cross-sectional shape, so that the lower end 52 elastically contacts the belt line weather strip 20 without digging into the belt line weather strip 20, and the inner side surface 53 elastically contacts the interior material 2. The boundary between the roof weather strip 10 and the cover sealing material 50 and the belt line weather strip 20 are also clean and have excellent sealing properties.
Further, upon elastic contact with the cover seal material 50, the roof weather strip 10 and the belt line weather strip 20 are formed of a sponge material having a soft elastic surface, and a material having a higher hardness than the sponge material on the surface is used. Since the backing has a two-layer structure, a large bite by the cover sealing material 50 is unlikely to occur, so that wrinkles do not occur on the surfaces of the roof weather strip 10 and the belt line weather strip 20, and the assembly is highly aesthetic. State can be maintained.
Further, since the cover sealing material 50 is removable, the adjustment of the adjusting device 5 by removing the cover sealing material 50 can be easily performed.

In the present embodiment, the adjusting device 5 is covered from the inside of the vehicle by the cover sealing material 50. However, the cover device 50 is not limited to the adjusting device 5 but may be provided on the inside of the quarter glass 1 by the cover sealing material 50. Can be obscured.
In addition, the outer side surface 54 of the cover seal material 50 is used for positioning the quarter glass 1 by elastically contacting the inner side surface of the quarter glass 1, but is not necessarily in contact with the inner side surface of the quarter glass 1. You may.
