Description

  The present invention relates to a weather strip for fixed glass that is attached to the periphery of a fixed glass of a vehicle door.

  Conventionally, some doors of vehicles such as automobiles have a fixed glass attached. The fixed glass is fitted into the opening of the door after a fixed glass weatherstrip for sealing the fixed glass is mounted on the peripheral edge thereof.

  The weather strip for fixed glass includes a main body portion having a substantially U-shaped cross section having an insertion groove portion into which the fixed glass is inserted on the inner peripheral side, and mounting portions provided on both the inside and outside of the main body portion. Each of the attachment parts is composed of a connecting part extending from the main body part and a lip part extending from the tip of the connecting part so as to cover the periphery of the door opening (inner panel or outer panel). It has a structure having an outer peripheral groove portion into which an inner panel or an outer panel is inserted.

  However, in the conventional weatherstrip for fixed glass, when water infiltrates from the outside of the vehicle into the weatherstrip (outer peripheral groove on the outside of the vehicle) at the upper side of the mains, the infiltrated water becomes the base of the main body. There is a risk of getting over the vehicle and entering the vehicle through the outer peripheral groove on the inside of the vehicle.

In view of this, in recent years, there is also a weather strip that is provided with a lip-shaped protrusion on the base portion of the main body portion and restricts water that has entered the outer peripheral groove portion outside the vehicle from getting over the base portion (for example, (See Patent Document 1).
Japanese Patent Application Laid-Open No. 2002-307954

  However, in the weatherstrip for fixed glass described in JP-A-2002-307954, the protrusion does not come into contact with the door sash, so that there is a possibility that water may get over the protrusion and enter the inside of the vehicle. And since the protrusion part is provided only in the corner part of the weatherstrip for fixed glass, there also exists a possibility that water may permeate from other parts. Furthermore, wind noise may occur in the gap between the door sash and the fixed glass weatherstrip during vehicle travel.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a weather strip for fixed glass that can suppress the intrusion of water into the vehicle.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. A weather strip for fixed glass that seals between the periphery of the opening of the vehicle door and the periphery of the fixed glass fixed to the opening,
A main body portion having a substantially U-shaped cross-section comprising an inner side groove portion and a vehicle inner side wall portion and a vehicle outer side wall portion extending from both ends of the base portion, and having a peripheral edge portion of the fixed glass inserted therein. As well as
A projecting base portion projecting from the outer peripheral side of the base portion is provided in substantially the entire longitudinal direction of the upper side portion and the predetermined vertical side portion attached along the door frame of the vehicle door ,
A seal lip that abuts the bottom of the sash of the door frame is provided on the outer peripheral side of the base portion at the tip of the protruding base ,
The fixed glass weather strip, wherein the protruding base portion is formed to be thicker than at least the sealing lip and larger than the maximum width of the insertion groove .

  According to the said means 1, since a seal lip contact | abuts to the bottom part of a sash, the malfunction that water gets over the base part of a main-body part and permeates into a vehicle inside can be suppressed. Further, it is possible to suppress wind noise generated in the gap between the sash and the fixed glass weather strip during vehicle travel. Furthermore, since the seal lip is provided in substantially the entire longitudinal direction of the upper side portion and the predetermined vertical side portion attached to the sash of the door frame, for example, the above-described operation can be performed more reliably than when the seal lip is provided only at the corner portion. An effect is produced.

Further , the seal lip is formed at the tip of the protruding base portion that is thicker than itself. In the configuration in which the seal lip is provided directly without providing the protruding base, for example, when the distance from the base of the main body to the bottom of the sash is long, a seal lip having a relatively long protruding length must be provided. For this reason, the seal lip is likely to be bent, and the contact state with the bottom of the sash may become unstable. On the other hand, according to this means, by providing the protruding base portion, the seal lip can be brought into contact with the bottom portion of the sash more reliably, and the contact state of the seal lip can be stabilized. In addition, by increasing the thickness of the protruding base, it is possible to increase the rigidity of the base, and reduce problems such as opening of the opening of the insertion groove more than set at the time of molding, etc. Stabilization of the insertion state of the fixed glass into the insertion groove can be achieved. As a result, it is possible to stabilize the mounting state of the fixed glass at the door opening and improve the sealing performance.

The thickness of the protrusion base portion, since it is larger than the maximum width of the insertion groove, effects of the above SL is further enhanced.

Means 2 . The fixed glass according to means 1 , wherein the protruding length of the protruding base is gradually changed along the longitudinal direction of the upper side and the predetermined vertical side according to the distance from the bottom of the sash. Weather strip.

According to the means 2 , by gradually changing the protruding length of the protruding base, the seal lip can be brought into contact with the bottom of the sash appropriately at each portion without gradually changing the protruding length of the seal lip. . If the protruding length of the seal lip itself is gradually changed, warping or distortion may occur and the sealing performance may be deteriorated. However, in this means, such a problem does not occur. Of course, corresponding to the shape of the door (distance from the bottom of the sash), for example, in a predetermined portion such as a corner portion, the protruding length of the protruding base is very close to 0, that is, the portion where the protruding base is hardly provided. There is no problem even if it can be done.

Means 3 . A door weather strip that seals between the vehicle door and the vehicle body is configured to be attached to a peripheral portion of the vehicle door by a predetermined fastening means,
In the position where the fastening means is attached, the positions of the seal lip and the protruding base portion in the vehicle inside / outside direction so as to bypass the attachment position of the fastening means are the longitudinal directions of the upper side portion and the predetermined vertical side portion. The weatherstrip for fixed glass according to means 1 or 2 , characterized by being gradually changed along

According to the means 3, when the fastening means such as a clip has to protrude into the sash due to the structure of the door frame, the seal lip is applied to the bottom of the sash without being obstructed by the fastening means. Can be touched. As a result, it is possible to more reliably suppress the entry of water and the generation of wind noise. Here, if the seal lip and the projecting base are “detoured to the outside of the vehicle at the attachment position of the fastening means”, the above effect is further enhanced.

Means 4 . The weatherstrip for fixed glass according to any one of means 1 to 3 , wherein the seal lip is inclined so that the tip thereof faces the outside of the vehicle.

According to the above means 4, it is possible to more reliably suppress the intrusion of water from the outside of the vehicle.

Means 5 . The weather strip for fixed glass according to any one of means 1 to 4 , wherein the upper side portion is an oblique side portion attached to a portion where the door frame is inclined along the longitudinal direction.

  Hereinafter, an embodiment will be described with reference to the drawings.

  As shown in FIG. 1, an automobile body 1 as a vehicle (vehicle body) is provided with a front door 2 as a vehicle door that can be opened and closed. A fixed glass 3 is attached to the front portion of the front door 2. The fixed glass 3 is fitted into the fixed glass opening 5 of the front door 2 after a fixed glass weather strip 4 (see FIG. 2) for sealing the fixed glass 3 is mounted on the peripheral edge thereof. ing. In FIG. 1, the left side of the automobile body 1 is illustrated, but in FIG. 2, a fixed glass weather strip 4 attached to the right front door 2 is illustrated. A door weather strip 40 (see FIG. 7) for sealing between the front door 2 and the automobile body 1 is attached to the periphery of the front door 2 by a clip 41 as a fastening means. Here, the clip 41 is attached so as to protrude into the sash 21.

  Next, the fixed glass weather strip 4 (hereinafter simply referred to as “weather strip”) will be described. The weather strip 4 is molded by a predetermined mold apparatus. The weather strip 4 is formed of an olefinic thermoplastic elastomer (TPO) as an elastic material.

  More specifically, as shown in FIG. 2, the weather strip 4 includes a rear vertical side portion 9 attached along the division bar 8 (see FIG. 1) and a lower side portion 10 attached along the front door 2 main body portion. The front vertical side portion 12 and the upper oblique side portion (upper side portion) 13 attached along the door frame 11 are formed in a substantially annular shape corresponding to the outer peripheral shape of the fixed glass 3. The upper oblique side portion 13 is attached to a portion where the door frame 11 is inclined along the longitudinal direction. In the present embodiment, the front vertical side portion 12 corresponds to a predetermined vertical side portion.

  Next, the cross-sectional shape of the weather strip 4 will be described using the front vertical side portion 12 and the upper oblique side portion 13 as an example. As shown in FIGS. 3 and 4, the front vertical side portion 12 and the upper oblique side portion 13 include a body portion 16 having a substantially U-shaped cross section having an insertion groove portion 15 into which the peripheral edge portion of the fixed glass 3 is inserted on the inner peripheral side. It has. The main body portion 16 includes a base portion 17, a vehicle inner side wall portion 18 that extends from both ends of the base portion 17, and a vehicle outer side wall portion 19. In order to enhance the holding force for holding the fixed glass 3 and the sealing performance with the fixed glass 3, the insertion groove 15 is narrower on the opening side than on the base 17 side of the maximum width W2. It has become. In the present embodiment, the width W2 on the base portion 17 side of the insertion groove 15 is set to be substantially the same as the thickness of the fixed glass 3, and therefore is shown as the thickness W2 of the fixed glass 3 in the drawing.

  Further, a base protrusion 20 as a protruding base is formed on the outer peripheral side of the base portion 17 in substantially the entire longitudinal direction of the front vertical side portion 12 and the upper oblique side portion 13, and the tip end portion of the base protrusion portion 20 is A seal lip 22 is formed to protrude. The seal lip 22 is inclined so that the tip thereof faces the outside of the vehicle.

  The thickness W1 of the base protrusion 20 is slightly different depending on each part, but is formed wider than at least the thickness of the seal lip 22 and the maximum width W2 of the insertion groove 15.

  Further, as shown in FIG. 2, the protrusion length T of the base protrusion 20 is also the length of the front vertical side 12 and the upper oblique side 13 in accordance with the shape of the door frame 11 (distance from the bottom 21 a of the sash 21). It gradually changes along the direction. For example, as shown in FIG. 5, at the corner portions of the front vertical side portion 12 and the upper oblique side portion 13, the protruding length T of the base protruding portion 20 is extremely close to 0, that is, there is almost no protruding base portion. . Accordingly, in this corner portion, the base protrusion 20 may be omitted in consideration of the distance from the bottom 21 a of the sash 21, and the seal lip 22 may be provided directly on the base portion 17.

  As shown in FIGS. 6 and 7, in the front vertical side portion 12, the attachment position of the clip 41 is moved to the outside of the vehicle so as to correspond to the attachment position of the clip 41 for fastening the door weather strip 40. A bypass portion 45 is formed so that the positions of the base protrusion 20 and the seal lip 22 in the vehicle interior / exit direction gradually change along the longitudinal direction of the front vertical side portion 12 so as to bypass. Of course, the detour portion 46 is similarly formed in the upper oblique side portion 13 (see FIG. 2).

  Further, on the vehicle inner side of the front vertical side portion 12 and the upper oblique side portion 13, a connecting portion 25 formed to extend from the vehicle inner side wall portion 18, and a lip portion 26 extending from the distal end portion of the connecting portion 25 to the outer peripheral side Is provided.

  On the other hand, on the vehicle outer side of the upper oblique side portion 13, as shown in FIGS. 30 is provided. On the other hand, the vehicle outer side of the front vertical side portion 12 has a configuration in which the lip portion is omitted, and includes a pair of projecting portions 28a and 28b that project from the vehicle outer side wall portion 19 to the vehicle outer side. .

  Next, a structure for attaching the fixed glass 3 and the weather strip 4 to the fixed glass opening 5 will be described. As shown in FIGS. 3 and 4, the door frame 11 to which the front vertical side portion 12 and the upper oblique side portion 13 are attached includes an inner panel 31 and an outer panel 32, and a sash 21 is provided therebetween. As an attachment procedure, first, the fixed glass 3 is inserted into the insertion groove 15, and the weather strip 4 is attached to the entire circumference of the fixed glass 3. Then, the fixed glass 3 in this state is fitted into the fixed glass opening 5. In the mounted state, the main body 16 is inserted between the inner panel 31 and the outer panel 32 (in the sash 21 depending on the part), and the seal lip 22 at the tip of the base projection 20 abuts against the bottom 21 a of the sash 21. It becomes a state. Further, on the vehicle inner side, the lip portion 26 covers the vehicle inner side surface of the inner panel 31. On the other hand, a frame molding 35 is attached to the outer side of the outer panel 32 and the projecting portions 28a and 28b on the outer side of the front vertical side portion 12, and the outer side surface of the outer panel 32 on the outer side of the upper oblique side portion 13 by the lip portion 30. Will be covered.

  With the above configuration, water has entered the upper oblique side portion 13 from the outside of the vehicle into the weather strip 4, that is, the outer peripheral groove portion 50 (see FIGS. 4 and 5) formed by the outer side wall portion 19, the connecting portion 29 and the lip portion 30. Even in this case, the infiltrated water is guided to the front vertical side portion 12 along the outer peripheral groove portion 50 without getting over the base portion 17 of the main body portion 16, and flows out of the vehicle.

  As described in detail above, since the seal lip 22 contacts the bottom 21a of the sash 21 in substantially the entire longitudinal direction of the front vertical side portion 12 and the upper oblique side portion 13, water gets over the base portion 17 of the main body portion 16. It is possible to more reliably suppress problems such as entering the inside of the vehicle. Furthermore, it is possible to suppress wind noise generated in the gap between the sash 21 and the weather strip 4 when the vehicle is traveling.

  Since the seal lip 22 is formed at the tip of the base projection 20 that is thicker than itself, the seal lip 22 is more reliably brought into contact with the bottom 21a of the sash 21, and the contact state of the seal lip 22 is stabilized. Can be achieved. In addition, by making the thickness W1 of the base protrusion 20 wider than the maximum width W2 of the insertion groove 15, the rigidity of the base portion 17 can be increased, and the opening of the insertion groove 15 is more than set at the time of molding or the like. In addition to reducing problems such as opening the mouth, the insertion state of the fixed glass 3 into the insertion groove 15 can be stabilized. As a result, it is possible to stabilize the mounting state of the fixed glass 3 in the fixed glass opening 5 and improve the sealing performance.

  In addition, the protrusion length T of the base protrusion 20 is gradually changed along the longitudinal direction of the front vertical side 12 and the upper hypotenuse 13 in accordance with the distance from the bottom 21a of the sash 21. Thereby, the seal lip 22 can be appropriately brought into contact with the bottom 21 a of the sash 21 at each portion without gradually changing the protruding length of the seal lip 22. If the projecting length of the seal lip 22 itself is gradually changed, warping or distortion may occur and the sealing performance may be deteriorated. However, in this embodiment, such a problem does not occur.

  Further, since the detour portions 45 and 46 are provided in the front vertical side portion 12 and the upper oblique side portion 13, the attachment position of the clip 41 is determined at the attachment position of the clip 41 for fastening the door weather strip 40. The positions of the base protrusion 20 and the seal lip 22 with respect to the inside / outside direction of the vehicle gradually change along the longitudinal direction of the front vertical side portion 12 and the upper oblique side portion 13 so as to make a detour to the outside of the vehicle. Therefore, the seal lip 22 can be brought into contact with the bottom 21 a of the sash 21 without being obstructed by the clip 41. As a result, it is possible to more reliably suppress the entry of water and the generation of wind noise.

  Moreover, since the seal lip 22 is inclined so that the tip thereof faces the outside of the vehicle, water intrusion from the outside of the vehicle can be more reliably suppressed.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the fixed glass weatherstrip 4 to be mounted on the fixed glass 3 of the front door 2 is embodied. However, the present invention is not limited to this. For example, the fixed glass (quarter window) of the rear door is used. The present invention can also be applied to a weather strip for fixed glass to be mounted on the glass.

  (B) In the said embodiment, although the weatherstrip 4 for fixed glass is comprised by TPO, you may comprise by other raw materials, such as ethylene-propylene-diene copolymer rubber (EPDM).

  (C) In the above embodiment, the configuration of the base protrusion 20 and the seal lip 22 is embodied in the front vertical side portion 12 and the upper oblique side portion 13. However, the present invention is not limited to this. In the weather strip for fixed glass to be mounted on the upper side portion, it can be applied to the upper side portion attached along the substantially horizontal direction and the rear vertical side portion connected to the upper side portion.

  (D) Instead of the above embodiment, the base protrusion 20 may be omitted, and the seal lip 22 may be provided directly on the base 17 of the main body 16. However, in the configuration in which the seal lip 22 is directly provided without providing the base protrusion portion 20, for example, when the distance from the base portion 17 of the main body portion 16 to the bottom portion 21a of the sash 21 is long, the seal lip 22 having a relatively long protrusion length is used. The seal lip 22 is likely to be bent and the contact state with the bottom 21a of the sash 21 may become unstable. Therefore, it is more preferable that the base protrusion 20 is provided.

  (E) In the above-described embodiment, the thickness W1 of the base protrusion 20 is formed wider than the maximum width W2 of the insertion groove 15, but it is sufficient that the base protrusion 20 is formed thicker than at least the thickness of the seal lip 22. However, it is preferable to make the thickness W1 of the base protrusion 20 relatively thick in order to increase the rigidity of the base portion 17 and suppress the opening of the insertion groove 15.

  (F) In the above embodiment, the bypass portions 45 and 46 are provided so as to bypass the attachment position of the clip 41 for fastening the door weather strip 40 to the outside of the vehicle, but provided so as to bypass the inside of the vehicle. May be. However, in view of the possibility of water entering the vehicle through the attachment hole of the clip 41 and the possibility of wind noise generated by the clip 41, it is more preferable to make a detour to the outside of the vehicle.

  (G) In the above-described embodiment, the seal lip 22 is inclined so that the tip thereof is directed toward the vehicle outer side, but may be configured to be inclined so as to be directed toward the vehicle inner side. However, inclining so as to face the outside of the vehicle can more reliably suppress water intrusion from the outside of the vehicle.
