  For this reason, in a sashless door type automobile, a roof side weather strip that is securely attached to the periphery of the opening of the vehicle body and contributes to weight reduction of the automobile has been demanded.

In order to solve the above-mentioned problem, the present invention of claim 1 is a roof side weather strip that is attached to the periphery of a vehicle body opening of a sashless door type automobile body and seals between the periphery of the vehicle body opening and the door glass. ,
The roof side weather strip is formed of a sponge material, and has a mounting base that is attached to the periphery of the vehicle body opening, a seal holding part that is formed on the inner surface of the mounting base and is substantially parallel to the door glass, It has a hollow seal part that is formed on the door glass side surface of the seal holding part and contacts the tip of the door glass, and a seal lip part that is formed at the tip of the seal holding part and contacts the inner surface of the door glass,
The seal holding part is formed in a substantially triangular section with a pointed tip from a seal holding part first wall formed on the vehicle outer side and a seal holding part second wall formed on the vehicle inner side, and has a hollow part inside. The hollow portion is formed with a reinforcing rib portion connecting the seal holding portion first wall and the seal holding portion second wall,
The thickness of the seal holding portion first wall between the portion where the hollow seal portion and the seal holding portion first wall are continuous and the portion where the seal holding portion first wall and the reinforcing rib portion are continuous is the seal holding portion first wall. Is formed thinner than the wall thickness of the other parts,
The mounting base is a roof side weather strip for automobiles which is mounted on the periphery of the vehicle body opening with a double-sided adhesive tape.

In the first aspect of the present invention, the entire roof side weather strip is formed of a sponge material, so that the weight of the roof side weather strip can be reduced and the weight of the automobile can be reduced.
The roof side weather strip includes a mounting base that is attached to the periphery of the vehicle body opening, a seal holding part that is formed on the inner surface of the mounting base and that extends substantially parallel to the door glass, and a door glass side of the seal holding part. A hollow seal portion formed on the surface and in contact with the front end of the door glass, and a seal lip portion formed at the front end of the seal holding portion and in contact with the inner surface of the door glass. For this reason, when the mounting base is attached to the periphery of the vehicle body opening, the hollow seal portion and the seal lip can be held by the seal holding portion and can be reliably brought into contact with the door glass. Can be double sealed.

  Since the seal holding part is formed in a substantially triangular section with a pointed tip from the first wall of the seal holding part formed on the outer side of the vehicle and the second wall of the seal holding part formed on the inner side of the vehicle, Thus, the rigidity of the triangular seal holding portion can be improved, and the hollow seal portion and the seal lip portion can be reliably held.

  The seal holding portion has a hollow portion formed therein, and a reinforcing rib portion that connects the seal holding portion first wall and the seal holding portion second wall is formed in the hollow portion. This contributes to reducing the weight of the vehicle, improves the flexibility of the seal holding portion by the hollow portion, and improves the rigidity of the seal holding portion by the reinforcing rib portion, so that the hollow seal portion and the seal lip are improved. The part can be securely held.

The thickness of the seal holding portion first wall between the portion where the hollow seal portion and the seal holding portion first wall are continuous and the portion where the seal holding portion first wall and the reinforcing rib portion are continuous is the seal holding portion first wall. It was formed thinner than the thickness of the other part. For this reason, when the door glass contacts the hollow seal portion and presses the hollow seal portion seal wall downward, the root portion side of the seal holding portion maintains the shape as it is by the reinforcing rib portion, while the reinforcing rib portion And the seal holding part first wall can be rotated around the first wall, the seal wall vertical part of the hollow seal part can be bent downward, the hollow seal part seal wall is deformed and doubled against the door glass. The sealing performance between the hollow seal portion sealing wall and the door glass can be maintained without contact.

Has a door glass and a seal wall vertical portion formed substantially at a right angle. For this reason, the seal wall parallel portion abuts against the front end of the door glass, and the hollow seal portion seal wall is prevented from being bent in the extending direction of the front end of the door glass. It is possible to prevent buckling at the lower part of the door glass.

The present invention of claim 5 is the roof side weather strip for automobiles in which the thickness of the second wall of the seal holding portion is formed to be thicker than the thickness of the first wall of the seal holding portion.

In the present invention of claim 5, since the thickness of the second wall of the seal holding portion is formed to be thicker than the thickness of the first wall of the seal holding portion, the reinforcing rib portion causes the thickness of the seal holding portion from the first wall of the seal holding portion. Even when force is applied to the two walls, the shape of the seal holding portion can be maintained, and the sealing performance of the hollow seal portion and the seal lip portion can be ensured.

According to the sixth aspect of the present invention, the thickness of the first wall of the seal holding portion is the thickest between the portion where the first wall of the seal holding portion and the reinforcing rib portion are continuous from the portion continuous with the mounting base, and then the hollow. Between the portion where the seal portion and the seal holding portion first wall are continuous, the tip side is thick, and between the portion where the hollow seal portion and the seal holding portion first wall are continuous, and the portion where the seal holding portion first wall and the reinforcing rib portion are continuous This is a roof side weather strip for automobiles having the thinnest wall thickness.

In the present invention of claim 6, the thickness of the first wall of the seal holding portion is the thickest between the portion where the seal holding portion first wall and the reinforcing rib portion are continuous from the portion where the mounting base portion is continuous, and then the hollow. Between the portion where the seal portion and the seal holding portion first wall are continuous, the tip side is thick, and between the portion where the hollow seal portion and the seal holding portion first wall are continuous, and the portion where the seal holding portion first wall and the reinforcing rib portion are continuous The wall thickness was the thinnest. For this reason, when the door glass contacts the roof side weather strip, the space between the portion where the hollow seal portion and the seal holding portion first wall are continuous and the portion where the seal holding portion first wall and the reinforcing rib portion are continuous is between. When the portion is bent, the vertical portion of the seal wall of the hollow seal portion moves downward, and the tip of the door glass can be wrapped and sealed. Further, the lower surface of the door glass can be sealed without deformation of the seal holding portion second wall of the seal holding portion and without the seal lip portion moving greatly.

According to the seventh aspect of the present invention, the thickness between the portion where the hollow seal portion and the seal holding portion first wall are continuous and the portion where the seal holding portion first wall and the reinforcing rib portion are continuous is the hollow seal portion and the seal holding portion. This is a roof side weather strip for automobiles that is 80% or less than the thickness on the front end side from the portion continuous with the first wall.

In the present invention of claim 7, the thickness between the portion where the hollow seal portion and the seal holding portion first wall are continuous and the portion where the seal holding portion first wall and the reinforcing rib portion are continuous is the hollow seal portion and the seal holding portion. The thickness is 80% or less than the thickness on the tip side from the portion continuous with the first wall. For this reason, when the door glass presses the hollow seal portion seal wall downward, the portion where the seal holding portion first wall and the reinforcing rib portion are continuous bends downward to ensure the sealing performance of the hollow seal portion seal wall. Can do. Furthermore, since the thickness of the first end of the seal holding portion first wall is thick, it is possible to reduce the deformation of the portion on the front end side of the seal lip portion and maintain the sealing performance between the seal lip portion and the door glass.

The present invention according to claim 8 is the roof side weather strip for automobiles in which the thickness of the sealing wall of the hollow seal portion is the thinnest in the vicinity of the center where the door glass abuts.

In the present invention of claim 8, since the wall thickness of the hollow seal portion seal wall is the thinnest in the vicinity of the center where the door glass abuts, it is most likely to abut when the front end of the door glass abuts the hollow seal portion seal wall. Since the vicinity of the center is most easily bent, the seal wall of the hollow seal portion wraps around the front end of the door glass and can be reliably sealed.

According to the ninth aspect of the present invention, the seal lip portion includes a seal lip portion first lip that abuts against the inner surface of the door glass, and a seal lip portion second lip that abuts a trim attached to a flange at the tip of the periphery of the vehicle body opening. It is the roof side weather strip for motor vehicles which has this.

In the present invention of claim 9 , the seal lip portion includes a seal lip portion first lip that contacts the inner surface of the door glass, and a seal lip portion second lip that contacts the trim attached to the flange at the front end of the vehicle body opening. Have For this reason, the space between the door glass and the vehicle body opening periphery can be reliably sealed with two lips, and the space between the door glass and the trim can be covered to improve the appearance.

As described above, since the roof side weather strip is formed of a sponge material as described above, the weight of the roof side weather strip can be reduced and the weight of the automobile can be reduced.
The seal holding part can improve the rigidity of the triangular seal holding part with the mounting base as the base, and can reliably hold the hollow seal part and the seal lip part.
Since the seal holding part is formed with a hollow part inside and a reinforcing rib part is formed, the rigidity of the seal holding part can be improved by the reinforcing rib part and the hollow seal part and the seal lip part can be securely held. it can.
The thickness of the seal holding portion first wall between the portion where the hollow seal portion and the seal holding portion first wall are continuous and the portion where the seal holding portion first wall and the reinforcing rib portion are continuous is the seal holding portion first wall. Since the door glass is in contact with the hollow seal portion and presses the hollow seal portion seal wall downward, the base portion side of the seal holding portion is the reinforcing rib portion. Thus, while maintaining the shape as it is, the seal rib can be rotated about a portion continuous with the reinforcing rib portion and the first wall of the seal holding portion, and the vertical portion of the seal wall of the hollow seal portion can be bent downward. Therefore, the sealing property between the hollow seal portion sealing wall and the door glass can be maintained without double contact with the door glass.
Since the attachment base is attached to the periphery of the opening of the vehicle body with a double-sided adhesive tape, a heavy retainer made of metal can be eliminated, which can contribute to weight reduction of the automobile.

The seal lip portion 50 is in contact with the inner surface of the door glass 5 and the trim portion 70.

  In the roof side weather strip, the mounting base portion 20, the seal holding portion 30, the hollow seal portion 60, and the seal lip portion 50 are all formed of a sponge material in any of the upper side portion, the vertical side portion, and the corner portion. Therefore, the weight can be reduced and it can contribute to the weight reduction of a motor vehicle.

  When the attachment base 20 of the roof side weather strip 10 is attached to the vehicle body opening periphery 6, the hollow seal portion 60 and the seal lip 50 are held by the seal holding portion 30 formed integrally with the attachment base 20. The seal portion 60 and the seal lip portion 50 can be reliably brought into contact with the door glass 5, and the gap between the door glass 5 and the vehicle body opening peripheral edge 6 can be sealed.

  The attachment base 20 is formed in a substantially flat plate shape and is attached in close contact with the vehicle body opening periphery 6. A tape groove 25 that is slightly recessed is formed on the outer surface of the vehicle outer side portion 21 of the mounting base 20 (the surface facing the vehicle body opening peripheral edge 6), and a double-sided adhesive tape 26 is attached thereto. The double-sided adhesive tape 26 adheres the vehicle body opening peripheral edge 6 and the mounting base 20 to ensure a sealing property therebetween.

Although the attachment base 20 is attached with the double-sided adhesive tape 26, as shown in FIG. 1, the clip 24 can also be used together.

The clip 24 is attached through the attachment hole formed in the.

A seal holder 30 is formed on the inner surface of the mounting base 20 (the side opposite to the surface facing the vehicle body opening periphery 6).
The seal holder 30 is formed on the first wall 31 of the seal holder formed on the vehicle outer side (the side close to the door glass 5) of the mounting base 20, and on the vehicle inner side (the side away from the door glass 5) of the mounting base 20. The seal holding portion second wall 36 is formed.

  The seal holding portion first wall 31 is formed so as to extend substantially in parallel with the door glass 5 from the vicinity of the side edge of the inner surface of the mounting base 20 on the vehicle outer side. The seal holding part second wall 36 extends obliquely from the vicinity of the inner side of the inner surface of the mounting base 20 toward the front end of the seal holding part first wall 31. The tip of the seal holding portion first wall 31 and the tip of the seal holding portion second wall 36 are connected, and together with the mounting base portion 20, the seal holding portion 30 is formed in a substantially triangular cross section with a sharp tip. . For this reason, the rigidity of the seal | sticker holding | maintenance part 30 can be improved and the hollow seal part 60 and the seal lip | rip part 50 which are mentioned later can be hold | maintained reliably.

  The seal holding portion 30 has a seal holding portion hollow portion 38 formed therein, and a reinforcing rib portion 40 that connects the seal holding portion first wall 31 and the seal holding portion second wall 36 to the seal holding portion hollow portion 38. It is formed. The seal holding portion hollow portion 38 is divided by the reinforcing rib portion 40 into a seal holding portion first hollow portion 38a on the mounting base 20 side and a seal holding portion second hollow portion 38b on the distal end side.

  Since the seal holding part 30 has the seal holding part hollow part 38, the weight of the roof side weather strip 10 can be reduced and the weight of the vehicle can be reduced. Therefore, the hollow seal portion 60 and the seal lip portion 50 can be reliably held.

  In the present embodiment, the thickness of the seal holding portion first wall 31 is such that the seal holding portion first wall reinforcing rib connecting portion 33 (the seal holding portion first wall 31 and the reinforcing rib portion 40 starts from a portion continuous with the mounting base portion 20. The seal holding portion first wall root portion 32 is formed to be the thickest, and then the seal holding portion first wall hollow seal connecting portion 35 (the hollow seal portion 60 and the seal holding portion first wall). 31 is a thick portion between the seal holding portion first wall reinforcing rib connecting portion 33 and the seal holding portion first wall hollow seal connecting portion 35. The smallest thickness is formed.

  The thickness between the seal holding portion first wall reinforcing rib connecting portion 33 and the seal holding portion first wall hollow seal connecting portion 35 is 8 more than the thickness on the front end side from the seal holding portion first wall hollow seal connecting portion 35. It can be formed below. Therefore, as shown in FIG. 2, when the door glass 5 presses the hollow seal portion 60 in the direction of the mounting base portion 20, the seal holding portion first wall 31 is connected to the seal holding portion first wall reinforcing rib connecting portion 33. The seal wall vertical portion 65 of the hollow seal portion 60 moves in the direction of the attachment base portion 20, and deformation of the tip of the seal holding portion 30 is reduced to reduce the seal lip portion 50. The movement can be reduced and the sealing performance of the hollow seal portion 60 and the seal lip portion 50 and the door glass 5 can be maintained.

  The thickness of the seal holding part second wall 36 can be formed thicker than the thickness of the seal holding part first wall 31. In this case, the shape of the seal holding portion 30 can be maintained even when force is applied from the seal holding portion first wall 31 to the seal holding portion second wall 36 by the reinforcing rib portion 40, and the hollow seal portion 60 and the seal lip can be maintained. The sealability of the part 50 can be ensured.

  The hollow seal portion 60 includes a hollow seal portion holding wall 61 extending in a flat plate shape from the root portion of the seal holding portion first wall 31 and a circular arc shape from the tip of the hollow seal portion holding wall 61. It is formed from a hollow seal portion seal wall 62 connected to the vicinity of the center of the holding portion first wall 31. For this reason, the hollow seal portion holding wall 61 of the hollow seal portion 60 can hold the hollow seal portion seal wall 62 so as to abut the tip of the door glass 5.

  The hollow seal portion seal wall 62 has a seal wall parallel portion 64 formed substantially parallel to the door glass 5 in the vicinity of the hollow seal portion holding wall 61 and a portion continuous with the seal holding portion first wall 31 in the door glass. 5 and a seal wall vertical portion 65 formed substantially at a right angle. In this case, as shown in FIG. 2, when the door is closed, the seal wall parallel part 64 comes into contact with the tip of the door glass 5, and the seal wall vertical part 65 becomes a support column, and the seal holding part first wall reinforcing rib connection The hollow seal portion seal wall 62 can move downward with the portion 33 as the center, and the seal wall parallel portion 64 of the hollow seal portion seal wall 62 is prevented from bending in the extending direction of the front end of the door glass 5. be able to.

  At this time, the seal holding portion first wall hollow seal connecting portion 35 where the hollow seal portion seal wall 62 is continuous with the seal holding portion first wall 31 is the reinforcing rib portion 40 is continuous with the seal holding portion first wall 31. Since the seal glass is positioned closer to the distal end side of the door glass 5 than the first wall reinforcing rib connecting portion 33, when the door glass 5 presses the hollow seal portion seal wall 62 in the direction of the mounting base 20, the seal retention is performed. Coupled with the thin portion of the first wall 31, the seal wall vertical portion 65 of the hollow seal portion 60 can bend in the direction of the mounting base 20 while maintaining its shape, and the hollow seal portion seal wall 62 and the door The sealing property of the glass 5 can be maintained.

  Further, when the door glass 5 is positioned further in the direction of the mounting base 20 and the door glass 5 presses the hollow seal portion seal wall 62 downward, the reinforcing rib is maintained while the shape of the seal wall vertical portion 65 is maintained. The portion 40 can be bent, the deformation of the hollow seal portion seal wall 62 can be prevented, and the sealing performance with the door glass 5 can be maintained.

  As shown in FIG. 2, when the front end of the door glass 5 abuts against the hollow seal portion seal wall 62, the vicinity of the center is most likely to abut, but the wall thickness of the hollow seal portion seal wall 62 abuts on the door glass 5. Since the vicinity of the center is formed to be thinnest, the place is most easily bent, and the hollow seal portion sealing wall 62 wraps around the tip of the door glass 5 and can be reliably sealed. Further, the sealing property can be improved without the hollow seal portion seal wall 62 being waved and bent.

  A hollow seal portion lip 66 is formed at the end of the hollow seal portion holding wall 61 of the hollow seal portion 60 on the side opposite to the hollow seal portion seal wall 62. The hollow seal portion lip portion 66 abuts on the end of the garnish 80 attached to the vehicle body, covers and seals the gap between the garnish 80 and the roof side weather strip 10, and improves the appearance.

  The seal lip portion 50 is formed at the tip of the seal holding portion 30, and is attached to a seal lip portion first lip 51 that contacts the inner surface of the door glass 5 and a trim 70 attached to the flange 9 at the tip of the vehicle body opening peripheral edge 6. It has a seal lip portion second lip 52 that abuts. For this reason, the space between the door glass 5 and the vehicle body opening peripheral edge 6 can be surely sealed with two lips, and the space between the door glass 5 and the trim 70 is covered to improve the appearance from the outside of the vehicle. can do.

As shown in FIG. 2, the hollow seal portion 60 and the seal lip portion first lip 51 do not contact each other even if the seal lip portion first lip 51 bends when the door glass 5 abuts. Are formed apart.
