Description

  The present invention relates to a roof roof side weather strip for automobiles that seals between an upper portion of a door opening edge of an automobile body and a door glass of the door.

  2. Description of the Related Art Conventionally, in a seal structure that seals between a door opening edge of an automobile of a door provided with a door sash and a door, for example, an opening trim weather strip is attached to the flange of the opening edge of the vehicle body door, A door weather strip is attached to the outer periphery, and when the door is closed, the hollow seal portion of the opening trim weather strip contacts the bulging portion of the door sash, and the hollow seal portion of the door weather strip and the seal lip are the outer edges of the vehicle body door opening edge. It was in contact with the panel and sealed between the doors.

  At this time, the door glass which moves up and down in the door is held by a glass run provided on the inner peripheral side of the door sash, and is moved up and down in the groove portion of the glass run. The seal between the door glass and the door sash is made by the glass run.

  However, in this case, in the appearance of the side surface of the automobile, glass run, door sash, and center pillar are conspicuous around the door glass, and there is a need for improvement in design. Moreover, since a glass run exists between the door sash or the center pillar and the door glass, a gap exists on the surface between the door sash and the door glass, which is not preferable in terms of design.

  For this reason, as shown in FIG. 3, as a sashless door type automobile body, the door sash is eliminated and only the door glass 5 is moved up and down freely above the belt line portion of the door 1. Yes. As a result, on the side of the automobile, only the door glass 5 can be made to appear at the upper part from the belt line portion of the door 1.

  In this case, the seal between the upper portion of the door opening edge of the vehicle body and the door glass 5 is attached to the roof side weather strip 110 attached to the upper portion of the vehicle body opening edge 6 as shown in FIG. Is performed by contacting. A retainer 4 formed integrally with a luke molding 2 as a molding portion is attached to the vehicle body opening periphery 6.

  As shown in FIG. 4, the roof side weather strip 110 includes an attachment base portion 111 attached to the retainer 4 at the periphery 6 of the vehicle body opening portion, and a seal portion 150 that contacts and seals the upper end of the door glass 5. . The mounting base 111 includes a vehicle outer side wall 120, a vehicle inner side wall 130 and a bottom wall 140.

  The seal portion 150 is formed of a seal wall 151 that abuts on the upper end of the door glass 5 and a hollow portion 152. When the door glass 5 abuts, the seal wall 151 is bent into the interior of the hollow portion 152 and the upper end of the door glass 5 is It can be sealed so as to be wrapped (see, for example, Patent Document 1). A trim 170 is attached to the flange at the periphery 6 of the opening of the vehicle body, and a cover lip 159 extending from the roof side weather strip 110 abuts to cover the gap.

  However, in this case, unlike the sash door, the door glass 5 is not held by the door sash and the glass run at the upper and side outer peripheral edges, and the position of the upper end of the door glass 5 is easily shaken. At the same time, it becomes easy to bend outward. Therefore, when the door is closed, the position where the door glass 5 abuts on the seal portion 150 is changed, and the seal portion 150 is abnormally deformed, and the sealing performance may be lowered.

  In the case of the sashless door type, when the door 1 is closed with the door glass 5 raised, the door glass 5 abuts against the roof side weather strip 10 from the lateral direction, and the door glass 5 is kept closed. When moving up and down, it contacts the roof side weather strip 10 from below. For this reason, there is a limit to satisfy both of the sealing properties when contacting each other from the directionality.

  Therefore, as shown in FIG. 5, the hollow seal portion is divided into two parts and sealed at two locations on the vehicle inner side surface of the upper end and the upper end of the door glass 5. On the other hand, there exists what was made to seal with each divided | segmented seal part (for example, refer patent document 2-patent document 5).

In FIG. 5, the roof side weather strip 210 includes an attachment base 211 that is attached to the periphery 6 of the vehicle body opening, and a first seal part 250 that is two seal parts formed integrally with the attachment base 211. And the second seal portion 260.
The mounting base portion 211 includes a vehicle outer side wall 220, a vehicle inner side wall 230, and a bottom wall 240.
The first seal portion 250 is formed on the vehicle outer side of the mounting base portion 211, extends from the upper end and the root of the vehicle outer side wall 220 to form a hollow shape, contacts the tip of the door glass 5, and is sealed. .

  The second seal portion 260 extends from the vehicle interior side wall 230, and includes a side wall 263, a lip-shaped front end portion 261 formed at the front end of the side wall 263, and a hollow portion 262 inside the side wall 263. Further, a cover lip is formed at the vehicle interior front end of the side wall 263 and abuts against the trim 270 to cover the gap. In this case, the front end portion 261 that contacts the inner side surface of the door glass 5 has a lip shape and is deformed by being pressed by the door glass 5 when the door is closed, or by being caught when the door glass 5 is raised or lowered. As a result, the sealing performance may be reduced.

Moreover, in the door provided with the recent door glass fine raising / lowering system, when the door is opened, the upper end of the door glass 5 is slightly lowered so as to be detached from the roof molding 2, and when the door is closed, the door glass 5 is in a slightly lowered state. The upper end first comes into contact with the tip 261 first, and then the door glass 5 is slightly raised so that the upper end of the door glass 5 enters the roof molding 2. At this time, the upper end portion of the door glass 5 abuts only on the front end portion 261 of the second seal portion 260 with a large door closing load first, and then moves up and down while sliding along the surface of the front end portion 261. For this reason, the durability of the lip-shaped tip portion 261 is deteriorated, and the lip-shaped tip portion 261 is easily caught and deformed, and the sealing performance is lowered.

Since the first seal portion 50 is hollow and formed of a sponge material, it can be flexibly deformed. For this reason, the seal | sticker between the upper end of the door glass 5 and the 1st seal | sticker part 50 is securable. Moreover, since the 1st seal | sticker vehicle outer side holding wall 51 is hold | maintained with the molding outer panel 7, it can hold | maintain so that the upper end of the door glass 5 may not be displaced to the vehicle outer side.

  When the door glass 5 rises, the second seal tip portion 63 of the second seal portion 60 abuts on the vehicle inner side surface of the upper end portion of the door glass 5. As the door glass 5 is raised, the second seal tip 63 seals between the vehicle inner side surface of the door glass 5 and the second seal portion 60 while sliding and bending upward on the vehicle inner side surface of the door glass 5. To do.

  For this reason, it can seal double by the vehicle inner side surface of the upper end and upper end part of the door glass 5, and can improve a sealing performance. Furthermore, since the first seal portion 50 and the second seal portion 60 are formed separately, when the door is closed and when the door glass 5 is raised and lowered, the first seal portion 50 and the second seal portion 60 The deformations do not affect each other and can be sealed independently, and the sealing performance can be ensured.

  The second seal portion 60 includes a second seal wheel outer holding wall bent portion 62 and a second seal wheel outer holding wall bent portion 62 so that the cross section is further bent and deformed into an L shape when the door is in contact with the inner side surface of the door glass 5 when the door is closed. The two-seal vehicle inner side holding wall bent portion 68 can be bent. For this reason, when the door glass 5 abuts, the second seal wheel outer holding wall bent portion 62 and the second seal wheel inner holding wall bent portion 68 are surely flexibly bent and deformed, and the position of the door glass 5 is shifted. Even in this case, the second seal portion 60 can reliably contact and seal the door glass 5.

  Moreover, since the 2nd seal | sticker front-end | tip part 63 of the 2nd seal | sticker part 60 was made into the hollow shape instead of the lip shape, it is not caught and compared with a lip shape at the time of raising / lowering of the door glass 5, and does not deform | transform abnormally. Furthermore, since it is bent at a predetermined bent portion as described above when it comes into contact with the door glass 5, the overall change amount of the second seal portion 60 is small, and the sealing performance does not deteriorate.

Moreover, since the 2nd seal | sticker part 60 bends flexibly, it is not pressed down strongly on the door glass 5, and the 2nd seal | sticker part 60 is not caught at the time of raising / lowering of the door glass 5, and does not deform | transform abnormally.
Further, even if the door glass 5 abuts from the lateral direction when the door is closed, or the door glass 5 abuts from below when the door glass 5 is raised or lowered, the deformation of the first seal portion 50 and the second seal portion 60 affects each other. Therefore, each can be sealed independently, and sealing performance can be secured.

Next, the case where it has the fine raising / lowering system of the door glass 5 is demonstrated.
In the slight raising / lowering system of the door glass 5, when the door 1 is opened and closed while the door glass 5 is raised, the upper end of the door glass 5 does not collide with the lower end of the molding outer panel 7 of the roof molding 2. Thus, the door is opened slightly in a state below the lower end of the molding outer panel 7. When the door is open, the upper end of the door glass 5 is held at the slightly lowered position. When the door is closed, the upper end portion of the door glass 5 contacts the second seal portion 60 of the roof side weather strip 10 from the lateral direction at the above position.

Immediately after the door 1 is closed, the door glass 5 slightly rises again, and the upper end of the door glass 5 contacts the first seal contact wall 53 of the first seal portion 50 of the roof side weather strip 10 in the roof molding 2. It abuts and enters the inside of the first seal portion 50. The door glass 5 is sealed and held by the first seal portion 50 of the roof side weather strip 10 and the roof molding 2 without being sucked to the outside of the vehicle.
When the door glass 5 is moved up and down with the door 1 closed, the upper end of the door glass 5 first comes into contact with the second seal tip portion 63 of the second seal portion 60 and the tip portion 63 is bent while After sliding the vehicle inner side surface, the upper end of the door glass 5 comes into contact with the first seal portion 50.

When the door 1 is opened, the door glass 5 is slightly lowered by the door glass fine lifting system from the door glass closed state, that is, the upper end of the door glass 5 is lower than the lower end of the molding outer panel 7 of the roof molding 2. And then stops at that position, and then the door 1 is opened. At this time, since the upper end of the door glass 5 does not interfere with the lower end of the roof molding 2, the door 1 can be opened without affecting the door opening. Thus, the upper end of the door glass 5 is detached from the roof molding 2 and the roof side weather strip 10 as the door 1 is opened even if the occupant does not perform any special operation when the door is opened. As a result, the door can be opened outward.
And in the state which the door 1 opened, the door glass 5 is maintained in the state of the said slightly lowered position. When the door 1 is closed again, as described above, the door 1 is closed without interfering with the lower end of the roof molding 2, and then the door glass 5 is slightly raised again to be completely sealed.

  In the fine lift system for the door glass 5, the door glass 5 automatically moves up and down slightly as the door 1 is opened and closed as described above. Further, since the second seal wheel outer holding wall bent portion 62 and the second seal wheel inner holding wall bent portion 68 bend when contacting the door glass 5, the amount of change in the second seal portion 60 is small, and the seal There is no decline in sex.

The roof side weather strip 10 is made of synthetic rubber, thermoplastic elastomer, or soft synthetic resin for both solid material and sponge material. For example, EPDM rubber is used for synthetic rubber, olefinic elastomer is used for thermoplastic elastomer, and soft synthetic resin is used. As the resin, soft vinyl chloride or the like is used.
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 or a soft synthetic resin, it is cooled and solidified. Thereafter, it is cut to a predetermined length, and the production of the extruded part is completed.
