  However, in the door outer weatherstrip and its mounting structure shown in FIG. 11 described above, when the turn-back length L of the turn-up portion 25 of the flange portion 18 ′ of the door outer panel 12 ′ is longer than the specified value, the door outer There is a concern that a large force is required to hook the collar 24 at the lower end of the weather strip 26 or that the collar 24 cannot be hooked, so that the workability of assembling the door outer weather strip 26 is lowered. It was. Further, when the folded length L of the folded portion 25 of the flange portion 18 ′ of the door outer panel 12 ′ is shorter than the specified length, the flange 24 at the lower end of the door outer weather strip 26 is connected to the folded portion 25 of the flange portion 18 ′. There is a concern that the door allowance strip 26 may come off from the flange portion 18 'when, for example, when the window glass 17 is raised, the locking allowance when hooked on the lower end 25a is small or zero. As described above, there is a concern that the workability and assembly accuracy of the door outer weather strip 26 may be affected by the dimensional accuracy of the folded portion 25 of the flange portion 18 ′ of the door outer panel 12 ′.

  Further, the side wall 22 on the vehicle inner side of the mounting base portion 27 of the door outer weather strip 26 is formed to be longer downward than the side wall 29 on the vehicle outer side, and the flange portion 24 provided at the lower end of the side wall 22 is formed on the flange of the door outer panel 12 ′. Concerning that the weight of the side wall 22 on the vehicle outer side of the door outer weather strip 26 is increased and the weight of the entire door outer weather strip 26 is increased in order to be engaged with the folded portion 25 formed long downwardly of the portion 18 ′. In addition, there is a concern that the overall weight of the door outer panel 12 ′ may become heavy due to the folded portion 25 formed long downward in the flange portion 18 ′.

  For example, in a vehicle in which a decorative blackout tape is attached to the outer surface of the rear sash of the front door corresponding to the B-pillar at the center of the vehicle body, a portion on the rear end side of the door outer weather strip 26 (substantially reversed in cross section). The portion of the U-shaped mounting base 27 having a notch or the like provided on the side wall 22 on the vehicle inner side) covers the outer surface of the rear sash so that the entire length of the door outer weather strip 26 is substantially U-shaped in cross section. The mounting base 27 having a substantially inverted U-shaped cross section of the door outer weather strip 26 is fitted to the flange portion 18 ′ of the door outer panel 12 ′ from the top downward, and the rear end side of the door outer weather strip 26 is formed. Of the door outer weather strip 26 in two-way assembly work in order to assemble the portion in the vehicle width direction from the vehicle outer side (side) toward the vehicle inner side. With (attached) workability there was a concern that also serves to decrease.

  In view of the above, the present invention eliminates the concern that the workability and assembly accuracy of the door outer weather strip depend on the folding accuracy of the folded portion of the flange portion of the door outer panel, and the door outer weather strip. It is another object of the present invention to provide a door outer weather strip that can reduce the weight of the door outer panel and improve the workability of assembling the door outer weather strip to the door outer panel and its mounting structure.

In order to achieve the above object, a door outer weather strip mounting structure according to claim 1 of the present invention includes a door outer weathering on a flange portion of a door panel raised at a vehicle outer periphery of a window glass insertion port of an automobile door. A door outer weather strip mounting structure to which a strip is attached, wherein the door outer weather strip with respect to the flange portion includes a side wall disposed outside the vehicle of the flange portion and an upper wall intersecting with an upper portion of the side wall. The mounting base portion is configured, a seal lip portion elastically contacting the outer surface of the window glass is provided on the upper wall, and a projection portion having a locking claw portion penetrating the flange portion in the thickness direction is provided on the side wall. provided toward the inner surface inside the vehicle, the flange portion is provided with a hole for passing the protrusion portion, said door panel is a door outer panel and de An outer reinforcement, and the flange portion is joined between a rising portion on the vehicle outer side of the door outer panel, a folding portion on the vehicle inner side following the rising portion, and the rising portion and the folding portion. It consists of the upper edge of the door outer reinforcement, the hole is provided in the rising part, and the upper edge and the folded part are each provided with a notch facing the hole. and said that you are.

With the above configuration, the locking projections penetrate the flange portion of the door panel from the vehicle outer side (side) toward the vehicle inner side in the vehicle width direction, and the claw portion is locked to the penetrating terminal edge of the flange portion. Thus, the door outer weather strip is firmly fixed to the flange portion. The thickness (plate thickness) of the flange part is higher in dimensional accuracy than the folding accuracy of the conventional folded part of the flange part, so that the claw part penetrates in the thickness direction of the flange part and does not rattle the through end edge of the flange. Engage with. The seal lip portion elastically contacts the outer surface of the window glass and pushes the mounting base together with the protrusion to the outside of the vehicle, and the claw portion, which is the locking portion of the protrusion, abuts against the penetrating end edge of the flange portion without rattling. Thus, the door outer weather strip is stably fixed to the flange portion. Since the mounting base does not have a long side wall facing downward inside the conventional vehicle, the locking force of the door outer weather strip is insufficient or excessive due to the folding accuracy of the folding side of the conventional vehicle inner side wall or flange ( Concerns such as difficulty in mounting) are resolved.
In addition, a protrusion for locking the door outer weather strip is inserted into the hole provided in the flange portion of the door panel from the outside of the vehicle toward the inside of the vehicle, and the upper end surface, the lower end surface, and the front and rear side end surfaces of the hole portion The projection is surrounded on all sides, and it is positioned and supported stably without rattling, tilting or slipping out. The door panel includes a door outer panel and a reinforcing door outer reinforcement, and the flange portion includes a flange portion of the door outer panel and an upper edge portion of the door outer reinforcement, that is, a flange portion.
In addition, a notch is formed on the lower end side of the folded portion of the flange, and the notch at the rising edge of the flange or the notch at the upper edge of the door outer reinforcement is exposed in the notch. ). The notch portion at the upper edge portion of the door outer reinforcement can be formed notch from the upper end of the upper edge portion downward and easily compared to the hole portion and with rougher processing accuracy than the hole portion. It is also possible to form a hole (hole-shaped part) between the upper end of the notch part of the folded part of the flange part and the lower end of the notch part of the upper edge part of the door outer reinforcement. Since the lower end of the folded portion of the flange portion does not need to be extended below the lower end of the hole portion or the notch portion of the door outer reinforcement (the vehicle longitudinal direction edge of the hole portion in the vehicle longitudinal direction, that is, the notched portion of the folded portion) This is necessary because the end edge of this is a portion for locking the claw portion of the locking projection portion), and the folding length of the folding portion is short, and the door outer panel is lightened.

  In the example of FIG. 1, the tip surface 8e of the protrusion 8 is formed with a width that is approximately the same as the width of the support plate 8b. However, in the example of FIG. 3B, the tip 8e of the protrusion 8 is supported. It is formed wider than the width of the plate portion 8b. In any case, a substantially trapezoidal tip end portion 8f including a pair of claw portions 8c is surrounded by a tip end surface 8e of the protrusion 8, a pair of front and rear inclined surfaces 8d, and a pair of front and rear locking surfaces 8a. There is no. The tip end face 8e of the protrusion 8 is preferably wide. This is because the front end surface 8e of the protrusion 8 in FIG. 3 (a) has moved to the outside of the vehicle within the range of the glass run (not shown) of the door 10 in the vehicle width direction when the vehicle is traveling at high speed. This is because it also has a function as a stabilizer for receiving the outer surface 17a of the glass 17.

  In FIG. 3A, the window glass 17 indicates a position in a free state when the vehicle is stopped, for example. However, the window glass 17 is sucked out of the vehicle when the vehicle is traveling at a high speed and the door frame shown in FIG. The outer surface 17a of the window glass 17 comes into contact with the front end surface 8e of the projection 8 of the door outer weather strip 1 when moving slightly toward the outside in the vehicle width direction with respect to the glass run on the inner side of 16, and the front end of the projection 8 When the surface 8e receives the outer surface 17a of the window glass 17, the window glass 17 is prevented from further outward movement in the vehicle width direction, and the window glass 17 is stably supported.

  The substantially trapezoidal protrusion tip 8f of the protrusion 8 protrudes toward the vehicle inner side of the vehicle inner surface 20a of the folded portion 20 of the flange portion 18 of the door outer panel 12, and the vehicle inner surface 20a of the folded portion 20 and the window. It is located between the outer surface 17a of the glass 17. The upper wall 3 of the door outer weatherstrip 1 is positioned above the protrusion 8 so that the bent portion 18a at the upper end of the flange portion 18 has a gap in the lower surface 3a at the middle portion in the width direction of the upper wall 3. Opposed and positioned above the projecting tip 8f are a tip 3b facing the vehicle inner side of the upper wall 3 and a root portion 5a of the seal lip portion 5 projecting obliquely upward from the tip 3b toward the vehicle inner side. doing.

  The root portion 5 a of the seal lip portion 5 is disposed on the vehicle outer side with respect to the tip end surface 8 e of the projection portion 8. This is because when the window glass 17 moves to the outside of the vehicle and the outer surface 17a of the window glass 17 comes into contact with the front end surface 8e of the protrusion 8, the outer surface 17a of the window glass 17 moves the root portion 5a of the seal lip portion 5. This is to prevent the seal lip portion 5 from being bent outwardly by pushing it strongly toward the outside of the vehicle (thereby reducing the sealing performance). If necessary, a root portion 5a of the seal lip portion 5 can be disposed on the outer surface 3c of the intermediate portion in the vehicle width direction of the upper wall 3 of the door outer weather strip 1.

  An intermediate seal lip 6 projecting from the inner surface 2a of the side wall 2 of the mounting base 4 of the door outer weatherstrip 1 is located below the projection 8 with a gap, and the intermediate seal lip 6 is located on the door outer panel. 12 of the rising portion 19 of the flange portion 18 is brought into elastic contact with and tightly contacted with the vehicle outer surface 19a, and the mounting base portion 4 is locked by the elastic reaction force (repulsive force) of the intermediate seal lip portion 6. 8 is urged toward the outside of the vehicle, and the engaging surface 8a of the claw portion 8c at the tip of the projection 8 abuts on the vehicle inner surface 20a of the folded portion 20 of the flange portion 18 so that the claw portion 8c The rattling between the locking surface 8a and the vehicle inner surface 20a of the folded portion 20 of the flange portion 18 is prevented, and the locking surface of the tip portion 6a of the intermediate seal lip portion 6 and the claw portion 8c of the projection portion 8 is prevented. 8a and the flange portion 18 in the thickness direction (vehicle width direction Sandwiched), outer door weather strip 1 is firmly fixed to the flange portion 18.

  Since the seal lip portion 7 at the lower end of the mounting base 4 is elastically contacted and closely contacted with the bent surface 12a on the vehicle outer side below the flange portion 18 of the door outer panel 12, the mounting base 4 is biased and supported upward. The door outer weather strip 1 is firmly and stably supported and fixed to the door outer panel 12 by the synergistic action of the seal lip portion 7, the intermediate seal lip portion 6 and the protrusion 8.

  The upper seal lip portion 5 elastically contacts (elastically contacts) the outer surface 17 a of the window glass 17 to give a repulsive force in the vehicle outer direction to the mounting base 4, and the locking projection 8 is the mounting base 4. The claw portion 8c on the front end side of the projection 8 is brought into contact with the surface 20a on the vehicle inner side of the folded portion 20 of the flange portion 18 of the door outer panel 12, and the surface 20a of the folded portion 20 is pressed. And the locking surface 8a of the claw portion 8c are prevented, and the door outer weather strip 1 is stably held by the flange portion 18.

  As a method for forming the door outer weather strip 1, for example, as shown in FIG. 1, a rigid mounting base 4 having a substantially inverted L-shaped cross section and an upper soft side protruding from the upper wall 3 of the mounting base 4 toward the inside of the vehicle. The seal lip portion 5 of the mounting base 4 and an intermediate soft seal lip portion 6 projecting from the inner surface 2a of the side wall 2 outside the vehicle, and the lower soft lip portion projecting from the lower end of the side wall 2 toward the inside of the vehicle. A seal lip portion 7 and a hard or soft plate-like base material (not shown) including a plurality of locking projections 8 that also protrude from the inner surface 2a of the side wall 2 toward the vehicle inner side are extruded (two A plurality of protrusions for locking by cutting a plate-shaped base material (not shown) that is continuously formed in the longitudinal direction of the weatherstrip by color molding and extruded integrally with the mounting base 4 by a technique such as press punching. 8 (unnecessary except for the protrusion 8) Plate base material is discarded by cutting), it is possible to obtain the outer door weather strip 1 of Figure 1.

  As another molding method of the door outer weather strip 1, as shown in FIG. 1, a hard mounting base 4 having a substantially inverted L-shaped cross section and an upper side protruding from the upper wall 3 of the mounting base 4 toward the vehicle inner side. The soft seal lip portion 5 of the mounting base 4, the intermediate soft seal lip portion 6 projecting from the inner surface 2 a of the side wall 2 outside the vehicle, and the lower side projecting from the lower end of the side wall 2 toward the inside of the vehicle. The soft seal lip portion 7 is formed continuously in the longitudinal direction of the weather strip by extrusion molding (two-color molding), and then mounted on the primary molded body including the mounting base portion 4 and the seal lip portions 5 to 7. A plurality of hard or soft projections 8 for locking are injected into the inner surface 2a of the side wall 2 of the base 4 using a synthetic resin material different from extrusion molding, another thermoplastic elastomer or another synthetic rubber material. For molding By bonding form I, can be obtained outer door weather strip 1 of Figure 1.

  4 compares the shape of the mounting base 4 of the door outer weather strip 1 of FIG. 3 with the mounting base of the conventional door outer weather strip of FIG.

  The conventional door outer weatherstrip shown in FIG. 11 has a vehicle-shaped side wall 22 which is a part of a mounting base portion having a substantially inverted U-shaped cross section, and a protruding stabilizer provided on a vehicle inner side surface 22 a below the side wall 22. 3 and the locking flange 24 provided on the vehicle outer surface 22b at the lower end of the side wall 22, the door outer weather strip 1 of FIG. Since the inner side wall 22, the stabilizer 23 provided on the inner side wall 22 of the vehicle, and the locking collar 24 are not provided (not required), the door outer weather strip 1 is made compact and simplified. It is lighter.

  Further, since there is no flange 24 at the lower end and there is no need to lock the lower end of the folded portion 20 of the flange portion 18 of the door outer panel 12 with the flange 24, the folded portion 20 is more folded than the conventional folded portion 25. The flange portion 18 can be reduced in weight, that is, the door outer panel 12 can be reduced in weight.

  In the conventional door outer weather strip 26 and its mounting structure shown in FIG. 11, when the turn-back length L of the turn-back portion 25 of the flange portion 18 ′ of the door outer panel 12 ′ is longer than specified, the door outer weather strip There is a concern that a large force is required to hook the collar portion 24 of 26, or that the collar portion 24 cannot be hooked, and the workability of assembling the door outer weather strip 26 is reduced. In the door outer weatherstrip 1 and its mounting structure of the invention, a projection 8 serving as a locking means is provided from the side wall 2 on the vehicle outer side of the mounting base 4 toward the vehicle inner side, and a conventional mounting base 27 (FIG. 11). This eliminates the need for the vehicle inner side wall 22 and the locking collar 24 at the lower end of the vehicle inner side wall 22. Incomplete locking due to variations in the vertical length of the folded portion 25 of the flange portion 18 'of the door outer panel 12', or the locking collar 24 is engaged with the lower end 25a of the folded portion 25 of the flange portion 18 '. Problems that require a great deal of force to be combined have been resolved.

  The projection 8 for locking the door outer weather strip 1 according to the present invention penetrates and engages in the thickness direction of the flange portion 18 of the door outer panel 12, and the thickness (plate thickness) of the flange portion 18 is the flange portion 18. Since the dimensional variation is extremely small compared to the length (vertical) direction length of the folded portion 20 of the folded portion 20, that is, the folded length (see symbol L in FIG. 11), the locking projection 8 can be smoothly and reliably flanged with a small force. The hole 18 (FIG. 4) or the notch of the portion 18 can be penetrated and locked.

  Further, in the conventional door outer weather strip 26 and its mounting structure shown in FIG. 11, the side wall 22 on the vehicle inner side of the mounting base 27 of the door outer weather strip 26 is formed longer downward than the side wall 29 on the outer side of the vehicle. In order to lock the flange portion 24 provided at the lower end of the side wall 22 to the lower end 25a of the folded portion 25 formed long downwardly of the flange portion 18 ′ of the door outer panel 12 ′, Concerns that the weight of the side wall 22 increases and the weight of the entire door outer weather strip 26 increases, and the weight of the entire door outer panel 12 ′ increases due to the folded portion 25 formed long downward on the flange portion 18 ′. Although there was a concern, the door outer weatherstrip 1 of the present invention has the mounting base 4 (FIG. 4) as described above. The vehicle-side side wall 2 and the upper side wall portion 3 are configured to exclude the side wall 22 (FIG. 4) on the vehicle inner side that is longer in the vertical direction than the side wall 2 on the vehicle outer side. Weight has been reduced. Further, a configuration in which the flange 24 provided at the lower end of the side wall 22 inside the vehicle of the conventional mounting base 27 (FIG. 11) is engaged with the lower end 25a of the folded portion 25 of the flange portion 18 ′ of the metal door outer panel 12 ′. Therefore, the folded portion 20 (FIG. 4) does not need to be formed long downward, the weight of the folded portion 20 is reduced, and the overall weight of the door outer panel 12 can be reduced.

  Further, in the conventional door outer weather strip 26 and its mounting structure shown in FIG. 11, the outer surface 17a of the window glass 17 is brought into contact with the side wall 22 on the vehicle inner side of the mounting base portion 26 having a substantially inverted U-shaped cross section. Although the projection-shaped stabilizer 23 is provided, the door outer weather strip 1 of the present invention is provided on the front end surface 8e of the locking projection 8 provided from the side wall 2 on the vehicle outer side of the mounting base 4 toward the vehicle inner side. Since the outer surface 17a of the window glass 17 is brought into contact with the tip surface 8e of the projection 8 and serves also as a stabilizer, the structure of the door outer weather strip 1 is simplified, reduced in weight, and reduced in cost.

  Further, in the conventional door outer weather strip 26 and its mounting structure shown in FIG. 11, for example, a mounting base 27 having a substantially inverted U-shaped cross section is attached to the flange 18 ′ of the door outer panel 12 ′ of the front side door 10. Assembling downward from above, the rear end side portion of the door outer weather strip 26 behind the mounting base 27 is placed on the outer surface 16a ′ of the rear sash 16a (see FIG. 2) of the door outer panel 12 ′ from the outside of the vehicle (side). The door outer weather strip 1 according to the present invention requires mounting in two directions, such as assembling in the vehicle width direction. Since it has a substantially inverted L-shaped cross section and is provided with a locking projection 8 from the side wall 2 outside the vehicle toward the inside of the vehicle, the door outer weather strip 1 can be Cross over the door outer panel body (12) at the upper edge (periphery of the window glass insertion port 30) and the rear sash 16a of the door outer panel 12 from the vehicle outer side (side) toward the vehicle inner side simultaneously from one direction. Thus, the workability of assembling the door weather strip 1 to the door outer panel 12 can be improved.
