An embodiment of the present invention will be described with reference to FIGS.
FIG. 3 is a front view of the rear door 1 of the automobile, and FIG. 2 is a front view of the glass run 10 of the rear door attached to the door frame 2 of the door 1. 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.

As shown in FIG. 2, the glass run 10 is attached to the linear part 11 formed by extrusion molding as a whole and the door frame corner part 2 e of the door frame 2. The glass run corner portion 12 is formed.
The straight portion 11 includes a glass run upper side portion 13 attached to the door frame upper side portion 2f of the door frame 2, a glass run front side vertical side portion 14 attached to the door frame front side vertical side portion 2g, and a door of the door frame 2. The glass run rear side vertical side portion 15 is attached to the frame rear side vertical side portion 2h.

  These extrusion-molded portions are molded by molding at the front and rear door frame corner portions 2e so as to have a shape corresponding to the door frame 2, and the glass run upper side portion 13 and the glass run front side vertical A glass run corner portion 12 on the front side is formed by connecting the side portion 14, and is molded by molding to connect the glass run upper side portion 13 and the glass run rear side vertical side portion 15 to form a rear side glass run. Corner portions 12 are formed.

First, the shape of the straight portion 11 of the glass run 10 according to the embodiment of the present invention will be described by taking the glass run rear side vertical side portion 15 as an example.
The glass run 10 has basically the same cross section of the glass run upper side 13 attached to the door frame upper side 2f and the glass run rear side vertical 15 attached to the door frame rear side vertical 2h. It has a substantially U-shaped cross-sectional shape. Further, the glass run front side vertical side portion 14 attached to the door frame front side vertical side portion 2g has a substantially similar U-shaped cross section.

As shown in FIG. 1, the glass run rear side vertical side portion 15 of the glass run 10 has a main body formed in a substantially U-shaped cross section from the vehicle outer side wall 20, the vehicle inner side wall 30, and the bottom wall 40. . As will be described later, the vehicle interior side wall 30 is larger than the vehicle exterior side wall 20 and is thick, and the substantially U-shaped cross section is formed in an asymmetric shape with a large vehicle interior.

The vehicle outer side wall 20 of the glass run 10 is formed in a substantially plate shape in cross section.
A vehicle outer side seal lip 21 extends from the vicinity of the front end of the vehicle outer side wall 20 toward the inside of the main body having a substantially U-shaped cross section. The vehicle exterior seal lip 21 will be described later.
A vehicle exterior design lip 22 is formed extending from the tip of the vehicle exterior side wall 20 toward the outside of the main body having a substantially U-shaped cross section of the glass run 10. For this reason, the door frame 2 can be covered with the vehicle exterior design lip 22 and the appearance can be improved.

The vehicle exterior design lip 22 includes a root portion 22c extending obliquely from the vehicle exterior side wall 20 in the vehicle outward direction, a distal end portion 22a formed on the distal end side of the vehicle exterior design lip 22, a root portion 22c, and a distal end portion. The tip portion 22a is formed between the bent portions 22b formed so as to be bent from the root portion 22c between 22a.

That is, the root portion 22c of the vehicle exterior design lip 22 extends obliquely from the front end of the vehicle exterior side wall 20 toward the bottom wall 40 in the vehicle exterior direction so as to form an acute angle with the vehicle exterior side wall 20. Furthermore, the vehicle exterior design lip 22 is bent at the bent portion 22 b, and the tip 22 a formed from the bent portion 22 b is further from the vehicle outer side wall 20 than the angle formed by the root portion 22 c with the vehicle outer side wall 20. It is formed to make a large angle.

The vehicle exterior side surface of the vehicle exterior design lip 22 is covered with a tip 51 of a garnish 50 that is a vehicle exterior design member. The garnish 50 is attached to the door frame rear side vertical side 2 h of the door frame 2. The back surface of the front end portion 51 of the garnish 50 is in contact with the vehicle outer surface of the vehicle exterior design lip 22 as shown in FIG. For this reason, the exterior side surface of the door frame 2 is covered with the garnish 50 to improve the appearance.

The front end portion 22 a of the vehicle exterior design lip 22 is attached so as to contact the inner surface of the front end portion 51 of the garnish 50. For this reason, the clearance between the front end portion 22a of the exterior design lip 22 and the front end portion 51 of the garnish 50 is eliminated, and the front end portion 51 of the garnish 50 covers the vicinity of the root portion 22c of the exterior design lip 22, thereby The sealing property between the design lip 22 and the garnish 50 can be ensured.

A contact rib 52 is formed on the back surface of the garnish 50. In the embodiment of the present invention, the reinforcing rib 53 can be formed on the opposite side of the abutment rib 52 from the tip portion 51 of the garnish 50. The reinforcing rib 53 can improve the rigidity of the front end portion 51 of the garnish 50 and protect the vehicle outer surface of the door frame 2.

The vehicle exterior design lip 22 rotates around the root portion 22c, which is a connecting portion with the tip of the vehicle exterior side wall 20, when high-pressure car wash water or the like hits the vehicle. The front end 22 a of 22 is formed so as to abut on a contact rib 52 formed on the back surface of the garnish 50.

For this reason, even when the front end portion 22a of the exterior design lip 22 is pushed by high-pressure car wash water or the like, the distal end portion 22a of the exterior design lip 22 contacts the abutment rib 52 of the garnish 50, The rotation of the outside design lip 22 can be stopped. Accordingly, a barrier against high-pressure car wash water or the like can be formed by the contact rib 52 of the garnish 50 and the outside design lip 22.

Therefore, the high-pressure car wash water that has entered from between the root portion 22c of the exterior design lip 22 and the tip portion 51 of the garnish 50 does not enter the door. The high-pressure water that has entered stops at the portion of the barrier formed by the abutment rib 52 of the garnish 50 and the outside design lip 22, flows down along the abutment rib 52, and flows from the lower part of the door 1 to the outside of the vehicle. It is discharged and does not penetrate into the interior of the door.

As described above, the vehicle exterior design lip 22 is bent at the bent portion 22b near the center, and the angle formed by the distal end portion 22a and the vehicle outer side wall 20 is larger than the angle formed by the root portion 22c and the vehicle outer side wall 20. Is formed so as to be large. For this reason, when assembling the garnish 50 to the door frame 2, variations in the dimensions of the door frame 2, the glass run 10, and the garnish 50 are absorbed to prevent the front end 22 a of the exterior design lip 22 from being caught. The front end portion 22 a of the vehicle exterior design lip 22 abuts on the back surface of the front end portion 51 of the garnish 50, and the sealing performance between the vehicle exterior design lip 22 and the garnish 50 can be ensured.

The vehicle exterior design lip 22 is preferably formed with a gradually decreasing thickness from the root portion 22c toward the tip portion 22a. In this case, the thickness from the root portion 22c to the tip portion 22a is adjusted, the rigidity of the vehicle exterior design lip 22 is adjusted, and the stress at the time of rotation of the vehicle exterior design lip 22 is adjusted. The sealing performance between the outer design lip 22 and the tip part 51 of the garnish 50 can be ensured.

As described above, the outside seal lip 21 extends obliquely toward the inside of the main body of the glass run 10 on the inside of the outside wall 20.
When the door glass 5 rises and the upper end of the door glass 5 slides inside the glass run rear side vertical side portion 15 of the main body of the glass run 10, The vehicle outer side seal lip 21 and a vehicle inner side seal lip 31 which will be described later elastically contact each other to seal between the side edge of the door glass 5 and the door frame 2.

Low sliding members can be provided on the surfaces of the vehicle exterior seal lip 21 and the vehicle interior seal lip 31 described later. In this case, when the door glass 5 moves up and down and slides on the glass run 10 at the vertical side, the contact area and frictional resistance between the door glass 5 and the glass run 10 are reduced, and the sliding resistance is reduced. Therefore, it is possible to prevent the generation of abnormal noise and to ensure smooth elevation. Further, even when the door glass 5 moves up and down due to the bending of the door glass 5 and the negative pressure during traveling, or even when the door glass 5 is bent and strongly pressed against the outer seal lip 21, the door glass 5 is slid. Smooth elevation can be ensured without increasing the dynamic resistance.

A vehicle outer side holding lip 23 is formed in the vicinity of the bottom wall 40 on the outer surface of the vehicle outer side wall 20 and the connecting portion. The door channel 2d attached to the door outer panel and the door inner panel is formed with an arcuate curved portion, and the vehicle outer side holding lip 23 is locked to the curved portion. The vehicle outer side wall 20 can be held by the door channel 2d.
For this reason, the vehicle outer side wall 20 can be reliably locked to the door channel 2d, and the space between the vehicle outer side wall 20 and the door channel 2d can be sealed.

The bottom wall 40 is formed in a substantially plate shape, and a bottom wall groove portion 41 is formed so as to be easily bent at a continuous portion between the vehicle inner side wall 30 and the vehicle outer side wall 20. At both ends of the outer surface of the bottom wall 40, bottom wall contact surfaces 44 are formed. The bottom wall contact surface 44 is formed to protrude so as to contact the door channel 2d.

On the inner surface of the main body of the glass run 10 of the bottom wall 40, a plurality of bottom wall recesses 42 are formed continuously in parallel in the longitudinal direction. The bottom wall recess 42 makes it easy for the bottom wall 40 to bend. Further, on the sliding surface 43 formed on the inner surface of the bottom wall 40, a low-sliding member is extruded or a low-sliding member such as urethane resin is extruded as in the case of the vehicle outer seal lip 21 and the vehicle inner seal lip 31. Has been applied. For this reason, sliding resistance with the door glass 5 can be reduced.

The vehicle interior side wall 30 is formed thicker and larger than the vehicle exterior side wall 20. For this reason, the glass run 10 can be held on the side surface of the door frame 2.
A vehicle interior design lip 32 extends from the front end of the vehicle interior side wall 30 in parallel with the vehicle interior side wall 30 in the outer surface side of the vehicle interior side wall 30, that is, in the vehicle interior direction. The vehicle interior design lip 32 and the vehicle interior side wall 30 sandwich the flange portion at the tip of the door channel 2d.

Similar to the vehicle outer side wall 20, a vehicle inner seal lip 31 extends obliquely from the tip of the vehicle inner side wall 30 toward the inside of the main body of the glass run 10. Since the vehicle interior seal lip 31 is longer and thicker than the vehicle exterior seal lip 21, the door glass 5 can be positioned on the vehicle exterior side when the door glass 5 enters the glass run 10. The step difference between the door frame 2 and the door glass 5 can be reduced. For this reason, air resistance and wind noise are reduced, which is preferable in terms of design.

A vehicle interior sub-seal lip 35 extends from the inner surface of the vehicle interior side wall 30 toward the back surface of the vehicle interior seal lip 31. When the door glass 5 presses the vehicle interior side seal lip 31 toward the vehicle interior side wall 30, the front end of the vehicle interior seal lip 31 is held to improve the sealing performance of the vehicle interior seal lip 31, and the vehicle interior side seal lip 31 31 is prevented from sticking to the vehicle interior side wall 30.

  A vehicle interior holding lip 34 is formed on the outer surface of the vehicle interior side wall 30 in the vicinity of the continuous portion with the bottom wall 40. The door channel 2d is formed with a bent portion, and the vehicle interior holding lip 34 is locked to the bent portion. Therefore, the glass run 10 can be held by the vehicle interior design lip 32 and the vehicle interior holding lip 34, and the vehicle interior side wall 30 can be held by the door channel 2d.

Near the center of the outer surface of the vehicle interior side wall 30, a vehicle interior holding projection 33 is formed continuously in the longitudinal direction. The vehicle inner side holding projection 33 is in contact with the inner surface of the door channel 2d on the vehicle inner side, and holds and seals the vehicle inner side wall 30 on the door channel 2d.

Below, the manufacturing method of the glass run 10 is demonstrated.
In the molding of the straight portion 11, synthetic rubber and thermoplastic elastomer are used as the molding material. For example, EPDM rubber is used for synthetic rubber, and polyolefin-based elastomer is used for thermoplastic elastomer.
In the case of synthetic rubber, it is conveyed to a vulcanizing tank after extrusion and heated by hot air or high frequency to vulcanize. In the case of a thermoplastic elastomer, it is cooled and solidified. Thereafter, it is cut to a predetermined length to produce an extruded part.

Next, the molded portion of the glass run corner portion 12 is formed by cutting the extruded member manufactured as described above into a predetermined dimension at a substantially right angle to the longitudinal direction, and the end portion of the cut extruded portion is formed into a mold. The molded part is sandwiched between molding dies, and a solid material for forming the molded part is injected into the cavity of the mold. The cross-sectional shape of the molded part is substantially the same as the cross-sectional shape of the extruded part.

As the molding material for molding, it is preferable to use the same type of material as that used for the extruded part. In the case of a thermoplastic elastomer, since the injected material is melted when injected into the mold, the extruded part and the molded part are integrally fused by the heat and pressure. Thereby, as shown in FIG. 2, in the glass run 10, the glass run front side vertical side portion 14, the glass run upper side portion 13 and the glass run rear side vertical side portion 15 are integrally connected by the glass run corner portion 12. Is done.
