As shown in FIG. 3, the door frame 2 is provided in the upper part of the door 1, and the door glass 5 is attached so that raising / lowering is possible. That is, a glass run 10 is attached to the inner periphery of the door frame 2 to guide the raising and lowering of the door glass 5 and to seal between the door glass 5 and the door frame 2. The side visor 50 is attached along the upper side of the door frame 2.
First, the door frame 2 and the glass run 10 will be described, and then the attachment structure of the side visor 50 will be described.

  As shown in FIG. 1, the door frame 2 to which the glass run 10 is attached is formed from a door outer panel 2a and a door inner panel 2b, and the tip portion of the door inner panel 2b is the tip portion to which the glass run 10 is attached. The door frame attachment surface 4 to which the vehicle interior side wall 22 of the glass run part 20 described later is attached is formed by bending. The front end portion of the door frame mounting surface 4 is bent at a substantially right angle to form the door frame flange portion 3 together with the door outer panel 2a.

  The door frame flange portion 3 is formed by bending the distal end of the door outer panel 2a so as to wrap the bent distal end of the door inner panel 2b in a hairpin shape. For this reason, the door frame mounting surface 4 and the door frame flange portion 3 are formed to be bent at substantially right angles to each other. At the base portion of the door frame flange portion 3, the tip portion of the door outer panel 2a that encloses the door inner panel 2b is bent downward to form a door frame flange portion hook 3a.

The door frame mounting surface 4 is formed with a door frame mounting recess 4a having a substantially U-shaped cross section for engaging a vehicle inner side wall engaging portion 28 of the vehicle inner side wall 22 described later. The door frame mounting recess 4a includes a door frame mounting recess upper wall 4b, a door frame mounting recess side wall 4d, and a door frame mounting recess lower wall 4c. Engage the vehicle interior side wall engaging portion 28 with the door frame mounting recess 4a to securely hold the vehicle interior side wall 22 to the door frame 2 and prevent the front end of the vehicle interior side wall and the occurrence of wrinkles on the seal lip. Can do.

As shown in FIG. 2, a terminal portion 12 is formed at the tip of the glass run 10.
Note that a glass run portion 20 attached to a vertical side portion of the door frame 2 is connected to the front and rear corner portions 13 of the glass run 10 downward. For this reason, the glass run part 20 can hold and seal not only the upper side of the door frame 2 but also the vertical side part of the side edge of the door glass 5. The glass run portion 20 attached to the connection portion between the upper side and the vertical side of the door frame 2 constitutes a corner portion 13 and connects the respective corner portions 13 of the upper side portion and the vertical side portion of the glass run portion 20 by molding. Formed.

  As shown in FIG. 1, the glass run 10 includes a glass run portion 20 attached to the inner periphery of the door frame 2 and a trim portion 30 attached to the door frame flange portion 3 formed at the tip of the door frame 2. Is done. First, the overall shape of the glass run 10 will be described separately for the glass run portion 20 and the trim portion 30, and attachment to the door frame 2 will be described later.

The glass run part 20 has a substantially U-shaped cross-sectional body portion composed of the vehicle outer side wall 21, the vehicle inner side wall 22, and the glass run part bottom wall 23, and the substantially U-shaped cross section from the tip of the vehicle outer side wall 21 and the vehicle inner side wall 22. A vehicle-side seal lip 24 and a vehicle-side seal lip 25 are extended obliquely in the interior direction. For this reason, the end part of the door glass 5 can slide inside the substantially U-shaped cross section composed of the vehicle outer side wall 21, the vehicle inner side wall 22 and the glass run part bottom wall 23 to hold the door glass 5. .

In the glass run portion 20, the vehicle interior side wall 22, the vehicle exterior seal lip 24 and the vehicle interior seal lip 25 are formed of a soft member. It is preferable to use an olefin-based thermoplastic elastomer as the soft member. Since the soft member is used, the vehicle outer side seal lip 24 and the vehicle inner side seal lip 25 can be flexibly bent, and when the door glass 5 rises, the end portion of the door glass 5 is reliably brought into contact with the door glass 5. The space between the glass 5 and the door frame 2 can be sealed.
If an olefinic thermoplastic elastomer is used, when the trim part 30 uses an olefinic synthetic resin, both are easy to weld and recycle is also easy. A foam can also be used.

The vehicle outer side wall 21 and the glass run part bottom wall 23 are formed of a hard member to be described later.
The vehicle outer side wall 21 is formed so that the root portion is thick and the thickness is made thinner toward the tip, and the vehicle outer side wall 21 is formed such that the inner surface is curved. For this reason, even if the rigidity of the vehicle outer side wall 21 is great and the curvature of the door frame 2 is large, the vehicle outer side wall 21 is not deformed such as wrinkles or undulations. Moreover, even if the door glass 5 approaches the vehicle exterior side, the vehicle exterior side wall 21 can hold | maintain the front-end | tip of the door glass 5, and the door glass 5 does not remove | deviate from the glass run part 20. FIG.

A surface film 21a is continuously attached to the outer surfaces of the vehicle outer side wall 21 and the trim portion bottom wall 33 described later. In the present embodiment, the surface film 21a uses a blend material of polystyrene (PS) and a dynamically crosslinked olefin-based thermoplastic elastomer (TPV). The blend material has a blend ratio of 10 to 50 parts by weight of polystyrene (PS) with respect to 100 parts by weight of the dynamically crosslinked olefin-based thermoplastic elastomer (TPV). For this reason, the adhesive force with the double-sided adhesive tape 40 which attaches the surface film 21a and the side visor 50 and is mentioned later can be strengthened. It is not necessary to treat the surface of the surface film 21a, and the side visor 50 can be reliably and easily attached.

When this skin layer 21a is used, the adhesive strength with the double-sided adhesive tape is as follows. After degreasing the surface, a double-sided adhesive tape was adhered to the skin layer 21a at room temperature, and left at room temperature for 24 hours. The peel strength at room temperature was 26.4 N / 10 mm. Also, a double-sided adhesive tape was adhered to the skin layer 21a at 80 ° C., and left at room temperature for 24 hours, and the peel strength at 80 ° C. was 8.6 N / 10 mm.
On the other hand, the adhesive strength when using only a dynamically crosslinked olefin-based thermoplastic elastomer (TPV) is as follows. After degreasing the surface, a double-sided adhesive tape was adhered to the skin layer 21a at room temperature and left at room temperature for 24 hours, and the peel strength at room temperature was 19.7 N / 10 mm. Further, a double-sided adhesive tape was adhered to the skin layer 21a at 80 ° C., and left at room temperature for 24 hours, and then the peel strength at 80 ° C. was 4.8 N / 10 mm.

It is preferable that the vehicle inner side wall 22 and the vehicle inner side seal lip 25 are larger than the vehicle outer side wall 21 and the vehicle outer side seal lip 24 and are formed thick. In this case, when the door glass 5 rises and is positioned in the glass run 10, the door glass 5 can be shifted to the outside of the vehicle, and the step on the outside surface of the door 1 can be reduced to improve the appearance. And wind noise can be reduced. Further, the vehicle interior side wall 22 can be securely attached to the door frame attachment surface 4 of the door frame 2.

It is preferable to apply a low sliding member to the surfaces of the vehicle outer side seal lip 24 and the vehicle inner side seal lip 25 (surfaces in contact with the door glass 5). As the low-sliding member, a low-sliding TPV (dynamically cross-linked olefin-based thermoplastic elastomer) can be formed in a thin layer, or can be used by applying a silicon paint or a urethane paint. Thereby, while raising / lowering of door glass can be made smooth, generation | occurrence | production of abnormal noise can be prevented.

A bottom wall lip 26 can be formed on the inner surface side of the glass run part bottom wall 23 from a connecting portion with the vehicle interior side wall 22. When the door glass 5 rises, the bottom wall lip 26 can abut the upper end of the door glass 5 against the bottom wall lip 26 to absorb the impact on the glass run part bottom wall 23. It is preferable to apply a low sliding member also to the surface of the bottom wall lip 26.

On the outer surface of the vehicle interior side wall 22, a vehicle interior side wall engaging portion 28 that engages with the door frame mounting recess 4 a is formed. The vehicle inner side wall engaging portion 28 has a substantially T-shaped tip. The front end of FIG. 1 extends upward to form a vehicle inner side wall engaging portion lip 28a, and the lower side of the front end extends downward to form a vehicle inner side wall engaging portion protruding portion 28b. The vehicle interior side wall engaging portion lip 28a contacts the door frame mounting recess upper wall 4b, and the vehicle interior side wall engaging portion protrusion 28b contacts the door frame mounting recess lower wall 4c.

The vehicle interior side wall engaging portion projection 28b is formed shorter than the vehicle interior side wall engaging portion lip 28a, and the vehicle interior side wall engaging portion lip 28a is bent and abuts against the door frame mounting recess upper wall 4b. For this reason, the vehicle interior side wall engagement portion protrusion 28b is bent by the vehicle interior side wall engagement portion lip 28a, so that the vehicle interior side wall engagement portion lip 28a departs from the vehicle interior side wall engagement portion projection 28b below the door frame mounting recess. By pressing against the wall 4c, the vehicle interior side wall engaging portion 28 can be reliably held in the door frame mounting recess 4a. Therefore, the vehicle interior side wall 22 is strongly held by the door frame mounting surface 4 and deformation of the vehicle interior side wall 22 can be prevented.

The lower end of the door frame mounting surface 4 (the lower end of the door frame mounting surface 4 in FIG. 1, and the door frame mounting surface 4 is bent and bent to reach the door inner panel 2b at the front end of the outer surface of the vehicle inner side wall 22. The vehicle interior cover lip 27 is provided in contact with the portion. The vehicle interior cover lip 27 is formed short and contacts the lower end of the door frame mounting surface 4 without covering the door inner panel 2b side.

For this reason, even if the curvature of the door frame 2 is large, the vehicle interior side cover lip 27 is formed short, and the vehicle interior side wall 22 is strongly held by the vehicle interior side wall engaging portion 28 on the door frame mounting surface 4. The cover lip 27 is in strong contact with the lower end of the door frame mounting surface 4 so that it does not move away from the door frame 2 or become wrinkled.

An inboard ridge 29 is formed on the glass run bottom wall 23 side of the outer surface of the inboard side wall 22 where the inboard side wall engaging portion 28 is formed. The vehicle inner ridge 29 abuts on a portion of the door frame mounting surface 4 closer to the door frame flange portion 3 than the door frame mounting recess 4 a and holds the vehicle inner side wall 22 together with the vehicle inner cover lip 27.

The vehicle inner side wall 22, the vehicle outer side seal lip 24, the vehicle inner side seal lip 25, the vehicle inner side cover lip 27, and the vehicle inner side wall engaging portion 28 are formed of a soft member described later. For this reason, the front end portion of the door glass 5 can be sealed by the vehicle outer side seal lip 24 and the vehicle inner side seal lip 25. Moreover, even if the vehicle interior side wall 22 bends flexibly and the door frame 2 is curved, it can be easily attached.

Next, the trim part 30 will be described. The trim part 30 has a substantially U-shaped cross section including a glass run side wall 31 formed integrally with the glass run part bottom wall 23, a body side wall 32 facing the vehicle body opening peripheral edge 6, and a trim part bottom wall 33. There is no.
The door frame flange portion 3 at the tip of the door frame 2 is inserted into the inside of the substantially U-shaped cross section, and is sandwiched by the trim portion 30 to hold the glass run 10 on the door frame 2. In the present embodiment, the glass run part bottom wall 23 of the glass run part 20 and the glass run side wall 31 of the trim part 30 are integrally formed of the same material as the same member. The glass run side wall 31 with 23 may be integrally formed by fusing both with a different material.

Two trim portion outer seal lips 34 are formed on the outer surface of the body side wall 32 of the trim portion 30 (the surface facing the vehicle body opening periphery 6). As shown in FIG. 1, when the door is closed, the two trim part outer seal lips 34, 34 come into contact with the vehicle body opening peripheral edge 6 to double seal between the vehicle body opening peripheral edge 6 and the door frame 2. .

  Two trim portion inner seal lips 35, 35 are formed on the inner surface of the body side wall 32 having a substantially U-shaped cross section, and three trims are formed on the inner surface of the glass run side wall 31 having a substantially U-shaped cross section. Part holding ridges 38, 38, 38 are formed. As shown in FIG. 1, when the door frame flange portion 3 is inserted into the interior of the trim portion 30 having a substantially U-shaped cross section, one surface of the door frame flange portion 3 is attached to the trim portion inner seal lips 35, 35. The other surface of the door frame flange portion 3 can be held by the trim portion holding protrusions 38, 38, 38. Further, the trim portion 30 can be stably held by the door frame flange portion 3.

A trim portion cover lip 37 is formed on the inner surface of the front end of the body side wall 32. As shown in FIG. 1, when the door frame flange portion 3 is inserted into the interior of the trim portion 30 having a substantially U-shaped cross section, a trim portion cover lip 37 is formed at the bent portion of the root portion of the door frame flange portion 3. The trim part 30 is prevented from coming off from the door frame flange part 3 by abutting.

A trim portion locking lip 36 is formed at the tip of the glass run side wall 31 toward the inside of the trim portion 30. When the door frame flange portion 3 is inserted into the substantially U-shaped cross section of the trim portion 30, the trim portion locking lip 36 engages with the door frame flange portion hook 3a. For this reason, even if the side visor 50 is bonded, the trim part 30 is difficult to come off from the door frame flange part 3.

The trim part 30 includes a glass run side wall 31, a body side wall 32, a trim part bottom wall 33, a trim part locking lip 36, a trim part cover lip 37, and a trim part holding protrusion 38, which are formed of a hard member. The trim part outer seal lips 34, 34 and the trim part inner seal lips 35, 35 are formed of a soft member, and the entire trim part is extruded by simultaneous molding of a hard member and a soft member. In addition, the vehicle outer side wall 21 of the glass run portion 20 is formed of a hard member as described above. For this reason, the rigidity of the part which adhere | attaches the side visor 50 can be enlarged.

As a result, the body portion of the trim portion 30 has high rigidity and can hold the door frame flange portion 3, and the trim portion outer seal lips 34, 34 can be flexibly adapted to the shape of the peripheral edge 6 of the vehicle body opening. The trim part inner seal lips 35, 35 can be brought into contact with the door frame flange part 3 and sealed.
Since the trim portion locking lip 36 and the trim portion cover lip 37 are formed of hard members, the trim portion 30 is strongly engaged with the door frame flange portion 3.

Next, the soft member and the hard member used in the glass run 10 according to the embodiment of the present invention will be described.
As the soft member, a dynamically crosslinked olefin-based thermoplastic elastomer (TPV) is used.
As the hard member, a blend material of a dynamically crosslinked olefin-based thermoplastic elastomer (TPV) and a polypropylene resin (PP) is used. The blend ratio is such that PP: TPV is 7: 3 to 4: 6. The Young's modulus of the hard member in this case is 0.8 to 1.4 GPa.
For example, the hard member having a blend ratio of PP: TPV of 7: 3 has a Young's modulus of 0.8 GPa, and this hard member can be used.

  Since the hard member used in the embodiment of the present invention has a Young's modulus of 0.8 to 1.4 GPa, an increase in insertion load when the glass run 10 is attached to the door frame 2 is prevented, and the glass run 10 The trim portion 30 can firmly hold the door frame flange portion 3. When the Young's modulus is less than 0.8 GPa, the force with which the trim portion 30 clamps the door frame flange portion 3 decreases, and when the Young's modulus exceeds 1.4 GPa, the glass run 10 is inserted when being attached to the door frame 2. The load increases, making it difficult to install.

  Moreover, since the blend ratio of a polypropylene (PP) and a dynamic crosslinkable olefin type thermoplastic elastomer (TPV) is 4-7: 6-3, the hard member used by embodiment of this invention is enough. It has rigidity and elasticity. Moreover, all are olefin polymers, and are excellent in weather resistance and recyclability. The blend ratio of polypropylene (PP) and dynamically cross-linked olefinic thermoplastic elastomer (TPV) is greater than 4: 6, and the amount of dynamically cross-linked olefinic thermoplastic elastomer (TPV) is greater than the amount of polypropylene (PP). When there is little, rigidity becomes low and the force in which the trim part 30 clamps the door frame flange part 3 falls.

  The blend ratio of polypropylene (PP) and dynamically crosslinked olefinic thermoplastic elastomer (TPV) is less than 7: 3 and the amount of dynamically crosslinked olefinic thermoplastic elastomer (TPV) is less and the amount of polypropylene (PP) When there are many, rigidity becomes large and the insertion load when attaching the glass run 10 to the door frame 2 increases, and attachment becomes difficult.

Next, the case where the side visor 50 is attached to the glass run 10 according to the embodiment of the present invention will be described.
As shown in FIG. 1, the glass run 10 is attached to the door frame 2.
First, the double-sided adhesive tape 40 is attached to the back surface of the mounting portion 52 on the front end side of the side visor 50.

Then, the curved tip portion 51 located at the tip of the attachment portion 52 of the side visor 50 is brought into contact with the upper end of the trim portion bottom wall 33 of the trim portion 30 of the glass run 10 to perform positioning, thereby trimming the trim portion 30. The double-sided adhesive tape 40 is pressed against the outer skin 21 a of the bottom wall 33 and the outer side wall 21 of the glass run part 20.
In addition, the double-sided adhesive tape 40 can be first adhered to the surface film 21a, and the attachment portion 52 of the side visor 50 can be pressure-bonded.
