  The glass run mounting structure shown in FIG. 5 and the glass run mounting structure shown in Patent Documents 1 and 2 have a corner included in the glass run mounting portion of the window opening (window opening). Local deformation such as wrinkles occurs in the glass run at the corner.

  That is, as shown in FIG. 5, the conventional glass run mounting structure is deformed so that the vehicle outer side wall 103 and the vehicle inner side wall 104 of the glass run 101 are widened because the tip portions 133b and 135b are parallel to each other. In contrast to this, position restriction is performed on the surfaces of the front end portions 133b and 135b. In this case, at the corner portion of the window opening, the glass run 1 is pulled in order to be positioned outside the corner at the portion that is in contact with the bent portions 133a and 135a of the tip portions 133b and 135b. The portions of the tip portions 133b and 135b that are in contact with each other at the front end of the panel are compressed because they are located inside the corners, but the inside and outside of the corners are pressed to restrict the position on the same surface. Therefore, local deformation (wrinkles) occurs in the glass run 101.

  When wrinkles are generated in the glass run, there is a problem that the position of the glass run is shifted from a predetermined position, adhesion (sealability) is lowered, and liquid intrusion such as water leakage is allowed.

  The present invention aims to solve such problems. That is, an object of the present invention is to provide a glass run mounting structure capable of suppressing the occurrence of local deformation such as wrinkles particularly at corner portions.

In order to solve the above problems and achieve the object, the glass run mounting structure of the present invention according to claim 1 is provided with the window openings of the outer panel and the inner panel, which are provided with window openings and constitute a vehicle door. In the glass run mounting structure in which the glass run for guiding the door glass is narrowed and fixed to the end of the part, the end of the outer panel and the inner panel are respectively separated from the direction approaching the panels. Bending portions are provided to bend, and the interval between the panels is widened from the bending portion toward the ends of the end portions of the outer panel and the inner panel, and the ends of the end portions of the outer panel and the inner portions distance between the tip of said end panels, said corner portion of the window opening is smaller than the flat portion of the window opening, this It is characterized in.

A glass run mounting structure according to a second aspect of the present invention is the glass run mounting structure according to the first or second aspect, wherein the pull-out prevention piece provided on the glass run is provided between the outer panel and the inner panel. It is characterized by abutting on the side farther from the window opening than the bent portion.

A glass run mounting structure according to a third aspect of the present invention is the glass run mounting structure according to any one of the first to third aspects, wherein the outer panel and the inner panel are provided at the ends of the end portions. A folded portion is formed that is folded toward the panels.

  According to the glass run mounting structure of the present invention described in claim 1, the bent portions are provided at the end portions of the outer panel and the inner panel so that the distance between the outer panel and the inner panel increases from the bent portion toward the front end of the panel. I have to. Therefore, the position of the glass run is restricted at the bent portion where the outer panel and the inner panel are closest to each other, and can be restricted by a point rather than a surface. Deformation can be suppressed.

  Further, when the vehicle door is constituted by the outer panel and the inner panel with the above structure, the cross section has a C-shaped cross section and expands toward the tip. Therefore, the portion of the glass run along the front end of the panel is less likely to be subjected to position restrictions, and can maintain the same posture as the flat portion of the window opening. Therefore, since the body of the seal lip provided on the glass run can be passed through the glass run having a constant cross section, a decrease in adhesion to the door glass can be suppressed.

  In addition, since the portion where the distance between the outer panel and the inner panel is narrow is formed by the bent portion, the glass run is difficult to come off, and the mounting strength of the glass run can be ensured.

  Moreover, since the panel surface becomes a guide surface by making the space | interval of an outer panel and an inner panel expand toward a panel front-end | tip from a bending part, the assembly | attachment property of a glass run improves.

In addition , at the corner portion of the window opening, the distance between the bent portion and the tip of the outer panel and the inner panel is narrower than the flat portion of the window opening portion, so that the glass run spread at the corner portion is suppressed. It is also possible to ensure the sealing pressure.

According to the glass run mounting structure of the present invention as set forth in claim 2 , the pull-out prevention piece provided on the glass run is in contact with the outer panel and the bent portion of the inner panel on the side farther from the window opening. Therefore, since the bent portion serves as a wall with respect to the slipping out of the glass run, the glass run is difficult to slip out.

According to the glass run mounting structure of the present invention as set forth in claim 3 , since the ends of the end portions of the outer panel and the inner panel are folded back toward each other, the glass run is formed. The distance between the seal lips that come into contact with the door glass can be reduced, and the seal pressure of the seal lip at the time of attachment can be ensured.

A portion of the vehicle 41 closer to the vehicle interior is referred to as the vehicle interior side, and a portion of the automobile 41 relative to the vehicle width direction is referred to as the vehicle outer side.

  A side door 30 is provided at the side of the automobile 41 so as to be freely opened and closed. The side door 30 is, for example, a vehicle door having a hinge door structure of a front door hinge type, and as shown in FIG. 2 and the like, an outer panel 33 that is a door panel on the outside of the vehicle, and an inner panel 35 that is a door panel on the inside of the vehicle, It is equipped with. In the present embodiment, the description will be given with the automobile 41 having a door only on the front side and a rear side as shown in FIG. 1, but the rear side such as a sedan or a hatchback is a seat. And the motor vehicle of the form which has a side door in the front side and the rear side may be sufficient. In that case, the glass run mounting structure described below may be applied not only to the front side door but also to the rear side door.

  The outer panel 33 and the inner panel 35 are joined by a hemming process at the peripheral edge of the outer panel 33 and are spot-welded as necessary to constitute a press door. The outer panel 33 and the inner panel 35 are formed by pressing a thin steel plate for automobiles such as a cold-rolled steel plate for automobiles and a high-tensile steel plate for automobiles to form a substantially rectangular window opening 31.

  A glass run 1 is attached to the end of the window opening 31 of the side door 30 in order to guide the door glass 39 and prevent liquid such as water from entering the vehicle body structure. As shown in FIG. 2 and the like, the glass run 1 is sandwiched and fixed between an outer panel 33 and an inner panel 35. The side door 30 is provided with a door glass 39 that can be raised and lowered.

  As shown in FIG. 2, the glass run mounting structure according to the embodiment of the present invention has a glass run 1 at least in the window opening 31 of the side door 30 in which the outer panel 33 and the inner panel 35 are assembled. Installed and configured. FIG. 2 is a cross-sectional view taken along the line II of FIG.

  In FIG. 2, the outer panel 33 is provided with a bent portion 33a at the end thereof. The bent portion 33a is a portion where the outer panel 33 is bent from the direction toward the facing inner panel 35 toward the door glass 39 (window opening 31). Similarly to the outer panel 33, the inner panel 35 is also provided with a bent portion 35a at the end thereof. The bent portion 35 a is a portion where the inner panel 35 is bent from the direction toward the facing outer panel 33 toward the door glass 39. That is, the bent portions 33a and 35a are bent in a direction away from a direction approaching each other panel (outer panel 33 or inner panel 35).

  The front end 33b side of the bent portion 33a is bent at an angle that increases the distance from the inner panel 35 toward the vehicle outer side. The front end 35b side of the bent portion 35a is bent at an angle that widens the distance from the outer panel 35 toward the vehicle inner side. That is, the interval between the tip portion 33b and the tip portion 35b is wider than the interval between the bent portion 33a and the bent portion 35a. In other words, the distance between the bent portions 33 a and 35 a increases toward the tips of the end portions of the outer panel 33 and the inner panel 35. Therefore, as shown in FIG. 2, the distal end portion 33 b and the distal end portion 35 b are substantially C-shaped in a sectional view in which the outer panel 33 and the inner panel 35 are combined.

  The interval between the bent portion 33a and the bent portion 35a is narrower than the interval between the bent portion 133a and the bent portion 135a in the conventional glass run mounting structure shown in FIG.

  The glass run 1 includes a bottom wall 2, a vehicle outer side wall 3 erected from the end of the bottom wall 2 on the vehicle outer side, and a vehicle inner side wall 4 erected from the end of the bottom wall 2 on the vehicle inner side. And the cross section is formed in a substantially U-shape and symmetrically. The glass run 1 is integrally formed by a known extrusion molding. For example, an elastic material or a synthetic material excellent in weather resistance and water-stopping properties such as ethylene-propylene-diene rubber (EPDM) and olefin-based thermoplastic elastomer (TPO). It is made of resin.

  The bottom wall 2 is formed in a substantially flat shape. The bottom wall 2 is formed with pull-out prevention pieces 9 and 10 at both ends of the vehicle outer side and the vehicle inner side, respectively. From the inside of the bottom wall 2 (the part where the bottom wall 2 and the edge of the door glass 39 abut), a projecting piece projecting from the vehicle outer end toward the vehicle outer side wall 3, and from the vehicle inner end And a projecting piece projecting toward the vehicle interior side wall 4.

  The pull-out prevention piece 9 protrudes from the vehicle outer end of the bottom wall 2 and is in contact with the back of the bent portion 33a of the outer panel 33, that is, the side away from the window opening. The pull-out preventing piece 10 protrudes from the inner end of the bottom wall 2 and is in contact with the back of the bent portion 35a of the inner panel 35, that is, the side away from the window opening.

  The vehicle outer side wall 3 is folded from the front end portion to the vehicle outer side and contacts the vehicle outer surface of the outer panel 33, and the vehicle outer side seal lip extends from the front end portion to the vehicle inner side wall 4 side. 6 are provided.

  The vehicle outer side cover lip 5 is formed so as to be folded from the front end portion of the vehicle outer side wall 3 to the vehicle outer side and to be engaged with the vehicle outer surface of the front end portion 33 b of the outer panel 33. The vehicle outer side cover lip 5 is formed so as to cover the front end portion 33 b of the outer panel 33.

  The vehicle exterior seal lip 6 extends from the distal end portion of the vehicle exterior side wall 3 toward the vehicle interior side wall 4 side, and is formed in a curved shape with the distal end portion directed toward the bottom wall 2 side. In addition, a flocking pile layer may be provided on the outside seal lip 6 at the sliding contact portion between the outside seal lip 6 and the door glass 39 via an adhesive. The flocked pile layer is made of, for example, polyamide resin such as nylon, polyester resin such as polyethylene terephthalate resin (PET resin), polyolefin resin, or the like. For this reason, frictional resistance with the door glass 39 is lowered, and operability and durability are improved.

  The vehicle interior side wall 4 is folded from the front end portion to the vehicle exterior side and is in contact with the vehicle interior surface of the inner panel 35, and the vehicle interior side seal lip is extended from the front end portion to the vehicle exterior side wall 3 side. 8 and.

  The vehicle interior cover lip 7 is formed so as to be folded from the front end portion of the vehicle inner side wall 4 to the vehicle outer side and to be engaged with the vehicle inner surface of the front end portion 35 b of the inner panel 35. The vehicle interior cover lip 7 is formed so as to cover the front end portion 35 b of the inner panel 35.

  The vehicle interior seal lip 8 extends from the distal end portion of the vehicle interior side wall 4 to the vehicle exterior side wall 3 side, and is formed in a curved shape with the distal end portion directed toward the bottom wall 2 side. In addition, a flocked pile layer may be provided on the inside seal lip 8 at the sliding contact portion between the inside seal lip 8 and the door glass 39 via an adhesive. The flocked pile layer is made of, for example, polyamide resin such as nylon, polyester resin such as polyethylene terephthalate resin (PET resin), polyolefin resin, or the like. For this reason, frictional resistance with the door glass 39 is lowered, and operability and durability are improved.

  FIG. 3 shows a glass run mounting structure at the corner of the window opening. The corner portion refers to a corner portion of the substantially rectangular window opening 31. FIG. 3 is a sectional view taken along line II-II in FIG. 3 basically has the same configuration as that of FIG. 2, which is a flat portion of the window opening 31 (corresponding to a rectangular side), but the distance between the bent portion 33a and the bent portion 35a remains the same. Further, the distance between the tip portion 33b and the tip portion 35b is narrower than that in FIG. 2 (a in FIG. 2> b in FIG. 3). That is, the spread angle of the substantially C-shaped section in a sectional view combining the outer panel 33 and the inner panel 35 is small.

  Therefore, the angle formed by the line C connecting the center between the bent portion 33a and the bent portion 35a, the center between the tip portion 33b and the tip portion 35b, and the tip portion 33b or the tip portion 35b is the window opening. The corner portion is smaller than the flat portion (θ1 in FIG. 2> θ2 in FIG. 3). This angle is preferably about 5 to 20 ° (where θ1> θ2).

  In this case, since the distal end portion 33b of the outer panel 33 and the distal end portion 35b of the inner panel 35 are formed in a C shape as described above, position regulation is performed on the bent portions 33a and 35a side of the distal end portions 33b and 35b. I do. For this reason, since the positional regulation of the glass run 1 at the bases of the vehicle outer side seal lip 6 and the vehicle inner side seal lip 8 (the end portions of the vehicle outer side wall 3 and the vehicle inner side wall 4) becomes loose, the outer panel 33 and the inner Even when the assembly portion of the glass run 1 constituted by the panel 35 has a corner, the generation of wrinkles on the glass run 1 can be suppressed.

  In other words, from the bent portions 33a and 35a of the outer panel 33 toward the tip portions 33b and 35b, the width increases toward the tip in the shape of a letter C, and the glass run along the tip side even at the corner portion of the window opening. 1 (end portions of the vehicle outer side wall 3 and the vehicle inner side wall 4) is not easily subjected to position restriction, and can maintain the same posture as the flat portion of the window opening. Therefore, the occurrence of local deformation such as wrinkles can be suppressed. Therefore, it is possible to ensure the adhesion of the vehicle outer side seal lip 6 and the vehicle inner side seal lip 8 to the glass surface of the door glass 39 while using the glass run 1 having a constant cross section.

  Further, at the corner portion of the window opening, the vehicle outer side wall 3 and the vehicle inner side wall 4 of the glass run 1 are greatly expanded outward (outer panel 33 or inner panel 35 side). In the flat part of the window opening part, it stays at the part according to the shape of the glass run 1, but in the corner part, it tends to become wider. Therefore, in the corner portion, the outer panel 33 and the inner panel 35 are supported on the support wall by making the spread angle of the substantially square C-shaped section in a sectional view combining the outer panel 33 and the inner panel 35 smaller than the flat portion. As a result, the spread can be suppressed and the sealing performance by the vehicle outer side seal lip 6 and the vehicle inner side seal lip 8 can be maintained.

  Further, as shown in FIGS. 2 and 3, since the panel surface length of the outer panel 33 and the inner panel 35 up to the bent portions 33a and 35b is relatively long, the panel strength can be ensured.

  Further, the space between the bent portions 33a and 35a is made narrower than before, so that the pull-out preventing pieces 9 and 10 come into contact with the respective panels behind the bent portions 33a and 35a (side away from the window opening). Therefore, it is difficult to get over the bent portions 33a and 35a in order for the glass run 1 to come out, and it becomes strong against the coming out (it becomes difficult to come off).

  In addition, when the glass run 1 is assembled, the portion from the bent portion 33a of the outer panel 33 toward the tip portion 33b and the portion of the inner panel 35 from the bent portion 33a toward the tip portion 35b spread in a C shape. Since it becomes a guide surface, the assembling property can be improved.

  As described above, in the glass run 1 mounting structure according to the first embodiment of the present invention, the bent portions 33a and 35a are provided at the end portions of the outer panel 33 and the inner panel 35, and from the bent portions 33a and 35a. The distance between the outer panel 33 and the inner panel 35 is increased toward the tip portions 33b and 35b. Therefore, the position of the glass run 1 is restricted by the bent portions 33a and 35a where the outer panel 33 and the inner panel 35 are closest to each other, and can be restricted not by a surface but by a point. Local deformation such as wrinkles in the run 1 can be suppressed.

  Moreover, when the side door 30 is comprised by the outer panel 33 and the inner panel 35 by the said structure, a cross section will have a breadth shape toward a front-end | tip. Therefore, the portion along the front end of the glass run 1 is less likely to be subjected to position restriction, and can maintain the same posture as the flat portion of the window opening. Therefore, the glass run 1 having a constant cross section can pass the postures of the vehicle outer side seal lip 6 and the vehicle inner side seal lip 8 provided on the glass run 1, and therefore, it is possible to suppress a decrease in adhesion to the door glass 39. .

  Further, by providing the bent portions 33a and 35a, a portion where the distance between the outer panel 33 and the inner panel 35 is narrow is formed, so that the glass run 1 is difficult to come off, and the attachment strength of the glass run 1 can be secured. it can.

  Moreover, since the panel surface becomes a guide surface by making the space | interval of the outer panel 33 and the inner panel 35 wide toward the front-end | tip of each panel from the bending parts 33a and 35a, the assembly | attachment property of the glass run 1 improves.

  Further, in the corner portion of the window opening portion, the distance between the bent portions 33a and 35a and the tips of the outer panel 33 and the inner panel 35 is narrower than the flat portion of the window opening portion. Therefore, the seal pressure can be secured.

  Further, the pull-out preventing pieces 9 and 10 provided on the glass run 1 are in contact with the outer panel 33 and the bent portions 33a and 35a of the inner panel 35 on the side farther from the door glass 39, so that the glass run 1 is removed. On the other hand, since the bent portions 33a and 35a serve as walls, the glass run 1 is difficult to come off.

  In addition, as shown in FIG. 4, the folding | returning part 33c folded toward the inner panel 35 is provided in the front-end | tip of the front-end | tip part 33b of the outer panel 33, and toward the outer panel 33 at the front-end | tip of the front-end | tip part 35b of the inner panel 35. A folded portion 35c that is folded may be provided.

  4, when the glass run 1 is attached, the vehicle outer side seal lip 6 and the vehicle inner side seal lip 8 can be arranged at the set positions, and the sealing pressure by these seal lips is ensured. can do. Further, since the position of the glass run 1 can be regulated by the folded portions 33c and 35c, the sealing performance is improved, and the state after the glass run 1 is assembled can be made constant.

  The present invention is not limited to the above embodiment. That is, those skilled in the art can implement various modifications in accordance with conventionally known knowledge without departing from the scope of the present invention. Of course, such modifications are included in the scope of the present invention as long as they have the configuration of the glass run mounting structure of the present invention.
