Description

The present invention relates to a glass run attached to a door frame formed on a vehicle door.

A door frame is provided on the upper part of the door body of the vehicle door, a channel-shaped glass run is fitted and locked in a groove formed on the inner peripheral edge of the door frame, and the door is locked by the glass seals inside and outside the car. It guides the ascending and descending of the glass and seals the inside and outside of the vehicle.

In the above glass run, the bottom wall, the outer side wall of the vehicle located on the outer side of the vehicle, and the inner side wall of the vehicle located on the inner side of the vehicle are formed as a basic skeleton (main body portion). Further, it is provided with a car outer seal lip and a car inner seal lip extending from the tips of both side wall portions or their vicinity toward the inside of the main body portion, respectively. Further, the glass run is sealed so that the main body is attached to a mounting portion provided along the inner circumference of the door frame, and the peripheral edges of the inner and outer surfaces of the door glass that moves up and down are sandwiched by both seal lips. The door. The glass run also supports the peripheral edge of the door glass, guides the door glass to move up and down, and suppresses rattling of the door glass.

By the way, when the door glass is positioned slightly below the fully closed position, the door glass tends to be displaced toward the inside of the vehicle. If the door glass vibrates in and out of the vehicle due to a car traveling on a rough road in this state, the door glass and the seal lip may momentarily separate from each other. When the seal lip and the seal lip come into contact with each other again, and the separation and contact are repeated, there is a possibility that an abnormal noise (striking sound) due to the contact may be generated. In particular, when the seal lip deteriorates over time and the elastic force decreases, the seal lip tends to separate from the door glass when the door glass vibrates, and the problem of generating abnormal noise becomes more remarkable.

As a technique for solving the above problem, for example, the one described in Patent Document 1 below is known. The structure of the glass run of Patent Document 1 will be described with reference to FIGS. 1 and 11. FIG. 1 shows a front view of the front door 100 on the left side of the automobile as viewed from the outside of the automobile. A door frame 320 is mounted on the upper part of the door body 210 constituting the front door 100. A window opening is formed by the door frame 320 and the upper end edge of the door body 210. A glass run 110 is mounted on the inner peripheral edge of the window opening and inside the door body 210 to guide the raising and lowering operation of the door glass 600.

FIG. 11 shows a vertical cross section (YY cross section of FIG. 1) of the vertical frame portion of the door frame 320. The glass run 110 is formed in a channel shape (U-shaped cross section) with the bottom wall 200, the car outer side wall 300, and the car inner side wall 400 as basic skeletons. A car outside seal lip 310 that comes into contact with the front surface (outside of the car) of the door glass 600 is formed on the car outside side wall 300, and a car that comes into contact with the back surface (inside of the car) of the door glass 600 at the tip of the car inside side wall 400. The inner seal lip 410 is integrally formed. Further, between the car inside seal lip 410 and the bottom wall 200, a sub lip 430 protruding in the direction opposite to the car inside seal lip 410 is formed toward the outside of the car.

The car inside seal lip 410 has a protruding surface 450 at a position protruding from the general surface of the back surface by providing a protrusion 440 on the back surface thereof. When the door glass 600 is displaced from the reference position to the inside of the vehicle, the first support state in which the tip of the sub lip 430 extending from the car inside side wall 400 and the protruding surface 450 slide in contact with each other and the tip of the sub lip 430 Is detached from the protruding surface 450, and the state of the sub-lip 430 can be changed to a second support state in which a portion of the sub-lip 430 on the root side of the tip portion abuts on the protrusion 440.

As a result, a protrusion 440 is provided on the back surface side of the car inside seal lip 410, the car inside seal lip 410 at that portion is thickened, and the protruding surface 450 of the protrusion 440 extends from the car inside side wall 400. Since the sub lip 430 that can come into contact with the car is provided, the force that the car inside seal lip 410 presses against the door glass 600 is increased, and even if the door glass 600 vibrates, the car inside seal lip 410 is the door. It is possible to prevent a situation in which the seal lip 410 is momentarily separated from the glass 600. For example, when the car inside seal lip 410 and the door glass 600 are brought into contact with each other from a separated state, an abnormality caused by the contact can be prevented. It is possible to prevent a situation in which a sound (striking sound) is generated.

JP-A-2018-149984

By the way, in the above-mentioned technique of Patent Document 1, when the door glass 600 vibrates due to the contact between the protrusion 440 having the protruding surface 450 and the sub lip 430 on the back surface of the car inside seal lip 410, the car inside seal lip 410 is the door. Although it prevents the glass from being separated from the glass 600, aging deterioration occurs not only on the car inside seal lip 410 but also on the sub lip 430. Therefore, there is a concern that the car inside seal lip 410 may be separated from the door glass 600 due to a decrease in the reaction force (pressing pressure) toward the back surface side of the car inside seal lip 410 due to the deterioration of the sub lip 430, and an abnormal noise may be generated again.

On the other hand, when the door glass 600 is positioned slightly below the fully closed position, the door glass 600 is likely to be displaced in the vehicle interior direction, so that the force with which the vehicle outer seal lip 310 presses the door glass 600 is weakened. Therefore, when the door glass 600 vibrates, the door glass 600 and the vehicle outer seal lip 310 may be momentarily separated from each other, and from this separated state, the door glass 600 and the vehicle outer seal lip 310 come into contact with each other again and are separated from each other. When the contact is repeated, an abnormal noise (striking sound) due to the contact may be generated, but Patent Document 1 cannot deal with this problem.

In addition, since there are various forms of the vehicle such as the size of the vehicle, the shape and size of the door glass, when the door glass vibrates, an abnormal noise generated between the door glass and the seal lip of the glass run is generated. The correspondence must be considered from the aspects of both the outside seal lip and the inside seal lip. The examination must be carried out in consideration of cost without affecting other functions in the glass run.

In order to solve the above problems, the present invention of claim 1 has a bottom wall, a car outer side wall, and a car inner side wall as a basic skeleton, and a car outer seal lip formed at or near the tip of the car outer side wall. A glass run having a car inside seal lip formed at or near the tip of the car inside side wall and attached to a groove formed in the door frame.

It is a glass run characterized by having at least one of the thick portions formed on the side of the car inside seal lip that does not come into contact with the door glass.

In the present invention of claim 1, the glass run is a first case having a car outer sublip formed so as to project diagonally from the car inner side of the car outer side wall on the bottom wall side of the base of the car outer seal lip. It protrudes diagonally from the outside of the car inner side wall on the bottom wall side of the base of the inner seal lip toward the root of the car inner seal lip, and a thick part is formed at the base of the car inner seal lip side. A second case having a car inner sub-lip, a third case having a thick portion formed at the base of the car outer seal lip, and a meat formed on the side of the car inner seal lip that does not come into contact with the door glass. A total of 15 cases, including a fourth case having a thick portion, an arbitrary combination of two cases out of the above four cases, an arbitrary combination of three cases, and a combination of all cases. Includes.

In the first case where a car outside sub-lip is formed that projects diagonally from the car inside of the car outside side wall on the bottom wall side of the base of the car outside seal lip, the force of the car outside seal lip pressing the door glass is applied to the car outside. The sub-lip supplements and can prevent the door glass and the car-outside seal lip from being momentarily separated when the door glass vibrates. The protruding direction of the vehicle outer sub-lip may be the bottom wall side or the base side of the vehicle outer seal lip.

The inside of the car has a wall that protrudes diagonally from the outside of the car inside side wall on the bottom wall side of the base of the car inside seal lip toward the base of the car inside seal lip and has a thick part at the base of the car inside seal lip. In the second case where the sub-lip is formed, since the car-inside sub-lip has a thick portion at the base of the car-inside sub-lip, the force with which the car-inside sub-lip presses the door glass from the inside of the car increases, and the door glass vibrates. It is possible to prevent the door glass and the car outside seal lip from being momentarily separated from each other.

In addition, even if the car inside sub lip deteriorates, it prevents the reaction force (pressing pressure) of the car inside seal lip from decreasing to the back side, and the car inside seal lip separates from the door glass, causing abnormal noise. Can be prevented.

In the third case having a thick portion formed at the base of the outer seal lip, the force of the outer seal lip pressing the door glass from the outside of the vehicle by the thick portion formed at the base of the outer seal lip. It is possible to prevent the door glass from being momentarily separated from the vehicle outer seal lip when the door glass vibrates.

Further, even if the outer seal lip deteriorates, it is necessary to prevent the reaction force (pressing pressure) of the outer seal lip on the door glass from being reduced by the thick portion formed at the base of the outer seal lip. This makes it possible to prevent the seal lip on the outside of the vehicle from being separated from the door glass and causing abnormal noise.

In the fourth case, which has a thick portion formed on the side of the car inside seal lip that does not abut on the door glass, the wall thickness on the left increases the force with which the car inside seal lip presses the door glass from the inside of the car, and the door glass. It is possible to prevent the door glass and the car outside seal lip from being momentarily separated when the glass vibrates.

In addition, the thick part formed on the side that does not come into contact with the door glass of the car inside seal lip even if the car inside seal lip deteriorates prevents the car inside seal lip from being deformed, and the car inside seal lip becomes a door glass. It is possible to prevent the reaction force (pushing pressure) of the vehicle from decreasing, and it is possible to prevent the seal lip inside the car from being separated from the door glass to generate an abnormal noise.

In addition, in the first to fourth cases or the combination method of the above four cases, various forms such as the size of the vehicle, the shape and size of the door glass, and the door glass are positioned slightly below the fully closed position. It can be selected according to the vibration state of the door glass in the state of being made to move.

The present invention of claim 2 is a glass run in which a thick portion is formed on the outer side wall portion of the vehicle from the root portion of the sub-lip on the outer side of the vehicle to the base portion of the seal lip on the outer side of the vehicle. In the present invention of claim 2, since a thick portion is formed on the vehicle outer side wall portion from the base portion of the vehicle outer sublip to the base portion of the vehicle outer seal lip, the vehicle outer seal lip presses the door glass. The complementary force of the vehicle outer sublip that complements the force is increased, and it is possible to prevent the door glass and the vehicle outer seal lip from being momentarily separated when the door glass vibrates.

In addition, even if the car outer sub-lip and the car outer seal lip deteriorate, the car outer sub-lip complements the force with which the car outer seal lip presses the door glass and the force with which the car outer seal lip presses the door glass due to the thick part. Since the decrease in force can be reduced, it is possible to prevent the outer seal lip of the vehicle from being separated from the door glass and generating an abnormal noise.

According to the third aspect of the present invention, the vehicle outer sublip having a thick portion formed on the vehicle outer side wall portion extending from the base portion of the vehicle outer sublip to the base portion of the vehicle outer seal lip is a glass protruding toward the bottom wall side. It's a run. When a thick part is formed on the outer side wall of the vehicle from the base of the outer sub-lip to the base of the outer seal lip, the length of the outer sub-lip on the outer side of the vehicle is the bottom wall side. Is shorter than the length of. As a result, the vehicle outer sublip is less likely to bend toward the vehicle outer seal lip side, and when the vehicle outer sublip protrudes toward the base of the vehicle outer seal lip, the force pushing the vehicle outer seal lip toward the door glass becomes stronger. , May interfere with the smooth vertical movement of the door glass.

In the present invention of claim 3, since the vehicle outer sublip having a thick portion formed on the vehicle outer side wall portion extending from the base portion of the vehicle outer sublip to the base portion of the vehicle outer seal lip protrudes toward the bottom wall side. , It is easier to bend than when it protrudes toward the base of the seal lip on the outside of the vehicle, and does not interfere with the smooth vertical movement of the door glass. Then, the force of the vehicle outer seal lip pressing the door glass is supplemented by the vehicle outer sub lip, and it is possible to prevent the door glass and the vehicle outer seal lip from being momentarily separated when the door glass vibrates.

In addition, even if the car outer sub-lip and the car outer seal lip deteriorate, the car outer sub-lip complements the force with which the car outer seal lip presses the door glass and the force with which the car outer seal lip presses the door glass due to the thick part. Since the decrease in force can be reduced, it is possible to prevent the outer seal lip of the vehicle from being separated from the door glass and generating an abnormal noise.

According to the fourth aspect of the present invention, the car outer sublip, the car inner sublip thick portion, the thick portion formed at the base portion of the car outer seal lip, and the car inner seal lip are formed on the side not in contact with the door glass. At least one of the thick portion or the thick portion formed on the outer side wall of the vehicle in the direction from the base of the outer sub-lip to the base of the outer seal lip is a mold for connecting the extruded members. It is a glass run that is formed in the mold forming portion at the time of molding or is continuously formed in the mold forming portion and the extrusion molding member connected to the mold forming portion.

In the present invention of claim 4, the car outer sublip, the car inner sublip thick portion, the thick portion formed at the base portion of the car outer seal lip, and the car inner seal lip are formed on the side not in contact with the door glass. At least one of the thick portion or the thick portion formed on the outer side wall of the vehicle in the direction from the base of the outer sub-lip to the base of the outer seal lip is a mold for connecting the extruded members. At the time of molding, it is formed in the mold forming portion or is continuously formed on the mold molding portion and the extrusion molding member connected to the mold forming portion, so that the above-mentioned is formed in a specific portion where abnormal noise is a concern. It can be dealt with by forming at least one of them.

Further, at the time of mold molding for connecting the extrusion molding members, the extrusion molding member is formed in the mold molding portion or continuously formed on the mold molding portion and the extrusion molding member connected to the mold molding portion. Is the thick part of the car outer sublip, the car inner sublip, the thick part formed at the base of the car outer seal lip, the thick part formed on the side of the car inner seal lip that does not come into contact with the door glass, or It is not necessary to form at least one of the thick parts formed on the outer side wall of the vehicle in the direction from the base of the outer sub-lip to the base of the outer seal lip, preventing weight increase and cost increase. Can be done.

In addition, the car outer sublip, the car inner sublip thick part, the car thick part formed at the base of the car outer seal lip, the car inner seal lip thick part formed on the side not in contact with the door glass, or , The other of the extrusion-molded member that accompanies the formation of the thick portion formed on the vehicle-outer side wall in the direction from the root of the car-outer sub-lip to the root of the car-outer seal lip in the extrusion-molded member during extrusion molding. Since it is not necessary to consider and consider the influence on the function of the above, the development time can be shortened.

According to the fifth aspect of the present invention, the car outer sublip, the car inner sublip thick portion, the thick portion formed at the base portion of the car outer seal lip, and the car inner seal lip are formed on the side not in contact with the door glass. In the thickened portion or the thick portion formed on the outer side wall of the vehicle from the root portion of the outer sub-lip to the base of the outer seal lip, the outer sub-lip protrudes toward the lower side of the vehicle. The length changes to be shorter, and the thick part of the car inner sub-lip, the thick part formed at the base of the car outer seal lip, and the meat formed on the side of the car inner seal lip that does not come into contact with the door glass. The thick part, the wall thickness formed on the outer side wall of the car from the base of the sub-lip on the outside of the car to the base of the seal lip on the outside of the car, decreases toward the lower side of the vehicle, and the wall thickness decreases to the extruded member and the wall thickness. It is a glass run that changes so that

According to the fifth aspect of the present invention, the sub-lip on the outside of the vehicle changes so as to be shorter toward the lower side of the vehicle, so that the sub-lip on the outside of the vehicle suddenly appears when the glass is moved up and down, or the vehicle. It is possible to prevent the outer sublip from suddenly disappearing and the movement of the glass from becoming irregular and unstable.

On the other hand, the thick part of the car inner sublip, the thick part formed at the base of the car outer seal lip, the thick part of the car inner seal lip formed on the side not in contact with the door glass, or the car outer sublip. As for the thick part formed on the outer side wall of the car from the root part of the car outer side to the base part of the car outer seal lip, the thick part is reduced and the base part of the car inner sublip of the extruded part formed on the extrusion molding member. Since the wall thickness changes to be the same as the car inner seal lip or the car outer side wall, the wall thickness of the car inner sub lip, the car inner seal lip, or the car outer side wall suddenly increases when the glass is moved up and down. Alternatively, it is possible to prevent the wall thickness from suddenly decreasing and the movement of the glass from becoming irregular or unstable.

The present invention of claim 6 is formed on the side of the car outer sublip, the car inner sublip, the thick portion formed at the base of the car outer seal lip, and the side of the car inner seal lip that does not come into contact with the door glass.

It is a glass run of the sixth embodiment of the present invention, and is the cross-sectional view corresponding to the line AA of FIG. 2 (b). It is sectional drawing which shows the mounting structure of the conventional glass run, and is the sectional drawing corresponding to the YY line of FIG. 1 (Patent Document 1).

The first embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 shows a front view of the front door 1 on the left side of the automobile as viewed from the outside of the automobile. A door frame 3 is mounted on the upper part of the door body 2 constituting the front door 1. A window opening is formed by the door frame 3 and the upper end edge of the door body 2. A glass run 10 is attached to the inner peripheral edge of the window opening and the inside of the door body 2 to guide the raising and lowering operation of the door glass 4. The present invention can be applied not only to the left front door 1, but also to the right front door and the left and right rear doors. It can also be applied to a sliding door that raises and lowers the door glass.

FIG. 2A is a front view of the glass run 10 as viewed from the outside of the vehicle in a simplified manner. The glass run 10 has a first extrusion-molded portion 11 corresponding to the horizontal frame portion of the door frame 3, a second extrusion-molded portion 12 corresponding to the vertical frame portion on the front side of the front door 1, and a vertical frame on the rear side. It is composed of a third extrusion-molded portion 13 corresponding to the portion. The front end portion of the first extrusion molding portion 11 is connected to the upper end portion of the second extrusion molding portion 12 by the first mold molding portion 14. The rear end portion of the first extrusion molding portion 11 is connected to the upper end portion of the third extrusion molding portion 13 by a second mold molding portion 15.

Here, the door glass 4 is directed toward the inside and outside of the vehicle due to a vehicle traveling on a rough road with the door glass 4 positioned slightly below the fully closed position between the door glass 4 and the glass run 10. The case of vibrating to the door will be described. When the door glass 4 is raised to the top and completely closed, the door glass 4 corresponds to the first extruded portion 11 of the glass run 10 and the second vertical frame portion on the front side of the front door 1. Since the door glass 4 is in contact with the extrusion-molded portion 12 of the above and the third extrusion-molded portion 13 corresponding to the vertical frame portion on the rear side and is supported from three directions, the door glass 4 is a car even when traveling on a rough road. Does not vibrate inward or outward.

When the door glass is slightly lowered and the contact with the first extrusion molding portion 11 is released, the door glass 4 mainly includes the second extrusion molding portion 12 corresponding to the vertical frame portion on the front side of the front door 1. It is supported in two directions by abutting against the third extrusion-molded portion 13 corresponding to the vertical frame portion on the rear side. At this time, when the automobile travels on a rough road or the like, the door glass 4 may vibrate in the inside / outside direction of the automobile, and the above-mentioned problem of abnormal noise may occur.

Further, when the door glass 4 is lowered, in the relationship between the door glass 4 and the glass run 10, the second extrusion-molded portion 12 corresponding to the vertical frame portion on the front side of the front door 1 and the vertical frame portion on the rear side are still formed. The door glass 4 is attached to the belt line 6 of the front door 1, for example, supported by the belt line weather strip, while remaining supported in two directions by contact with the corresponding third extrusion section 13. As a result, it is supported in substantially three directions. Therefore, at this stage, the vibration of the door glass 4 in the inside and outside of the vehicle is extremely small even when traveling on a rough road.

Therefore, in the present invention, the door glass 4 is attached to the belt line 6 of the front door 1 from the time when the door glass 4 is lowered and the contact of the glass run 10 with the first extrusion-molded portion 11 is released. For example, until it is also supported by the belt line weather strip and is supported in substantially three directions including the glass run 10, that is, the support of the door glass 4 is mainly the front of the glass run 10. When applied to a section in two directions due to contact with the second extrusion-molded portion 12 corresponding to the vertical frame portion on the front side of the door 1 and the third extrusion-molded portion 13 corresponding to the vertical frame portion on the rear side. It produces a high effect.

FIG. 3 is a cross-sectional view corresponding to the line AA of FIG. 2B, and is a connecting portion between the rear vertical frame portion of the second mold forming portion 15 and the corresponding third extrusion molding portion 13. It is in the vicinity. The glass run 10 has a bottom wall 20, a car outer side wall 30 and a car inner side wall 40 as a basic skeleton, and is formed in a channel shape (cross section is substantially U-shaped).

The bottom wall 20 is formed in a substantially plate shape, and a plurality of bottom wall recesses 22 are continuously formed in parallel in the longitudinal direction on the inner surface (contact side with the door glass 4) of the bottom wall 20. .. Then, the convex portions 23, 23 formed on the outer side of the groove portions 21, 21 are in contact with the door channel 5.

A car outside seal lip 31 that comes into contact with the door glass 4 is formed on the inside of the car outside side wall 30 toward the bottom wall 20, and a car outside seal lip 31 is formed on the tip portion of the car outside side wall 30. The car outside cover lip 32 is formed toward the opposite side. Since the vehicle outer cover lip 32 can double seal the vehicle outer surface of the door glass 4 together with the vehicle outer seal lip 31, rainwater, dust, and noise can be prevented from entering, and the sealing property can be improved.

Further, a car outer sublip 33 is formed which is formed at the tip of the car outer side wall 30 and projects diagonally from the inside of the car on the bottom wall 20 side to the side opposite to the bottom wall 20 from the car outer seal lip 31. The vehicle outer sub-lip 33 comes into contact with the back surface (vehicle outer side) of the vehicle outer seal lip 31 when the vehicle outer seal lip 31 is in sliding contact with the door glass 4. The vehicle outer sub-lip 33 may be formed so as to project diagonally toward the bottom wall 20 side.

On the other hand, on the outer side of the vehicle outer side wall 30, the vehicle outer side holding rib 34 and the vehicle outer side contact rib 35 that are locked to the door channel 5 having an arcuate curved portion are formed. Further, a locking portion 36 is formed at the bases of the vehicle outer seal lip 31 and the vehicle outer cover lip 32 toward the outer side of the vehicle, and the end portion of the door channel 5 is fixed.

At the tip of the car inside side wall 40, a car inside seal lip 41 that comes into contact with the door glass 4 is formed toward the bottom wall 20 side. Further, on the inside of the car inside side wall 40, a car inside holding lip 44 locked to the curved portion of the door channel 5 having an arc-shaped curved portion in the vicinity of the connecting portion with the bottom wall 20, and a car inside contact. A contact lip 45 is formed. The car inside side wall 40 is held by the curved door channel 5 by the car inside holding lip 44 and the car inside contact lip 45.

A car inside cover lip 42 is formed on the opposite side (car inside) of the car inside seal lip 41 at the tip of the car inside side wall 40. In the figure, the car inside cover lip 42 is drawn in a shape continuous with the car inside seal lip 41, but the present invention is not limited to this. The car inside cover lip 42 comes into contact with the tip of the door channel 5, prevents rainwater, dust, and noise from entering, and can improve the sealing property.

As a result, the vehicle outer sub-lip 33 comes into contact with the back surface of the vehicle outer seal lip 31, and the door glass 4 travels on a rough road with the door glass 4 slightly below the fully closed position. When the vehicle vibrates, the vehicle outer sub-lip 33 supplements the force with which the vehicle outer seal lip 31 presses the door glass 4, prevents the door glass 4 side of the vehicle outer seal lip 31 from separating from the door glass 4, and generates an abnormal noise. Can be prevented.

FIG. 4 shows a second embodiment of the present invention, in which the car inside seal lip 41 formed at the tip of the car inside side wall 40 is replaced with the car outside sub lip 33 of the first embodiment described above. A car inside sub-lip 43 having a thick portion 46 is formed at the base portion of the car inside seal lip 41 that protrudes diagonally from the outside of the car inside side wall 40 on the bottom wall 20 side toward the root portion. Other than that, it is the same as that of the first embodiment. Further, the thick portion 46 of the base portion of the car inside sub lip 43 is compared with the extrusion molding portion car inside sub lip 47 (FIG. 7) formed in the third extrusion molding portion 13 corresponding to the vertical frame portion on the rear side. It is formed thickly. This embodiment is also in the vicinity of the connecting portion between the rear vertical frame portion in the second mold forming portion 15 and the corresponding third extrusion molding portion 13.

As a result, the car inside sublip 43 is a car inside seal lip 41 when the door glass 4 vibrates due to traveling on a rough road with the door glass 4 positioned slightly below the fully closed position. It is possible to prevent the outside of the vehicle from separating from the door glass 4 and prevent the generation of abnormal noise.

Further, since the thick portion 46 of the car inside sublip 43 is thick, even if the car inside sublip 43 deteriorates, the reaction force (pushing pressure) to the back side of the car inside seal lip 41 is prevented from decreasing, and the inside of the car is prevented from decreasing. It is possible to prevent the seal lip 41 from being separated from the door glass 4 and generating an abnormal noise. In FIG. 4, the wall thickness portion 46 of the car inside sub lip 43 is thicker than that of the extrusion molding portion car inside sub lip 47 (FIG. 7) formed in the third extrusion molding portion 13. It is drawn with emphasis on the thick part so that you can see that it is.

The car inside sub-lip 43 prevents the car inside seal lip 41 from coming into close contact with the car inside side wall 40 when the door glass 4 is largely displaced inside the car, thereby preventing the generation of abnormal noise. It also has a role of holding the side end portion of the door glass 4.

5 to 7 show a third embodiment of the present invention, in which the car outside sublip 33 according to the first embodiment and the wall thickness portion 46 according to the second embodiment are formed. It has both a car inside sub-lip 43.

FIG. 5 is the same position as in FIGS. 3 and 4, and is in the vicinity of the connecting portion with the third extrusion molding portion 13. As shown in FIG. 6, at a slightly lower position, the thick portion 46 of the vehicle outer sublip 33 and the vehicle inner sublip 43 faces the vehicle lower side, and the vehicle outer sublip 33 is a vehicle as compared with FIG. The length of the outer sub-lip 33 is shortened, and the wall thickness of the car-inside sub-lip 43 is reduced as compared with FIG. Then, as shown in FIG. 7, the car-outer sub-lip 33 disappears at a further lower position, and the car-inside sub-lip 43 is the extrusion-molded part car-inside sub-lip 47 formed in the third extrusion-molded part 13. It is the same as the wall thickness of. FIG. 7 is a cross-sectional view of the third extrusion molding portion 13.

As a result, the force of the car outside seal lip 31 to press the door glass 4 from the outside of the car is supplemented by the car outside sub lip 33, and the force of pressing the door glass 4 from the inside of the car is increased by the thick portion 46 of the car inside sub lip 43. Therefore, it is possible to prevent the door glass 4 and the car outside seal lip 31 from being momentarily separated from each other when the door glass 4 vibrates. Further, since the thick portion 46 is provided at the base of the car inside sub lip 43, even if the car inside sub lip 43 deteriorates, the reaction force (pushing pressure) to the back surface side of the car inside seal lip 41 is prevented from decreasing. It is possible to prevent the car inside seal lip 41 from being separated from the door glass 4 and generating an abnormal noise.

Further, the vehicle outer sublip 33 formed continuously on the mold molding portion and the extrusion molding member connected to the mold molding portion changes so as to have a shorter length, and the car inner sublip 43 is a thick portion at the base portion. Since 46 decreases and changes so that the wall thickness becomes the same as that of the extrusion-molded part car inside sub-lip 47 formed on the extrusion-molded member, the car-outside sub-lip 33 suddenly appears and disappears when the door glass 4 is moved up and down. Further, it is possible to prevent the wall thickness of the car inside sub-lip 43 from suddenly increasing or decreasing and the movement of the door glass 4 from becoming irregular or unstable.

Further, at the time of mold molding, since it is continuously formed on the mold molding portion and the extrusion molding member connected to the mold molding portion, the extrusion molding member is formed with a wall thickness portion 46 of the vehicle outer sublip 33 and the vehicle inner sublip 43. It is not necessary to take measures to prevent the weight increase and cost increase. Further, since it is not necessary to consider and examine the influence on other functions of the extruded member due to the formation of the thick portion 46 of the car outer sublip 33 and the car inner sublip 43, the development time should be shortened. Can be done.

In the third embodiment, the car outer sublip 33 and the car inner sublip 43 have both thick portions 46, and the force for pressing the door glass 4 from both sides is increased. Therefore, the first embodiment is used. The car-outer sub-lip 33 can be formed thinner than that of the second embodiment, and the wall thickness of the car-inner sub-lip 43 can be made thinner than that of the second embodiment.

FIG. 8 shows a fourth embodiment of the present invention, which has a thick portion 48 formed at the root portion of the vehicle outer seal lip 31 in addition to the second embodiment described above. .. Further, the forming portion of the present embodiment was formed in a region continuous with the mold molding portion and the extrusion molding member connected to the mold molding portion at the time of mold molding.

As a result, when the door glass 4 vibrates due to traveling on a rough road with the door glass 4 positioned slightly below the fully closed position, the door glass 4 side of the car outside seal lip 31 is the door glass. By preventing the vehicle inside seal lip 41 from being separated from the door glass 4 and preventing the outside of the vehicle inside seal lip 41 from being separated from the door glass 4, it is possible to prevent the generation of abnormal noise.

Further, even if the car inside sub lip 43 and the car outside seal lip 31 deteriorate, the reaction force (pressing pressure) of the car inside sub lip 43 to the back surface side of the door glass 4 against the door glass 4 and the door glass 4 of the car outside seal lip 31 It is possible to prevent the reaction force (pushing pressure) on the surface side of the vehicle from decreasing, and prevent the vehicle outer seal lip 31 and the vehicle inner seal lip 41 from being separated from the door glass 4 to generate an abnormal noise. ..

In the fourth embodiment, both the thick portion 48 formed at the base of the car outer seal lip 31 and the thick portion 46 of the car inner sub lip 43 are provided, and the force for pressing the door glass 4 from both sides is exerted. Since the number is increased, the wall thickness of the wall thickness portion 46 of the car inside sub-lip 43 can be reduced as compared with the second embodiment.

FIG. 9 shows a fifth embodiment of the present invention, and in addition to the third embodiment described above, a wall-thick portion formed on the side of the car inside seal lip 41 that does not come into contact with the door glass 4. It has 49. Further, the forming portion of the present embodiment was formed in a region continuous with the mold molding portion and the extrusion molding member connected to the mold molding portion at the time of mold molding.

As a result, when the door glass 4 vibrates due to traveling on a rough road with the door glass 4 positioned slightly below the fully closed position, the car outside seal lip 31 moves the door glass 4 to the outside of the car. The force of pressing from the outside of the vehicle is supplemented by the sub-lip 33 on the outside of the vehicle, and the thick portion 46 of the sub-lip 43 on the inside of the vehicle and the thick portion 49 of the seal lip 41 on the inside of the vehicle increase the force of pressing the door glass 4 from the inside of the vehicle. It is possible to prevent the door glass 4 and the car outside seal lip 31 from being momentarily separated when the 4 vibrates.

Further, since the car inside seal lip 41 and the car inside seal lip 41 have a wall thickness portion 46 and a wall thickness portion 49 on the side that does not come into contact with the door glass 4, the car inside seal lip 41 and the car inside sub lip 41 are provided. Even if the car inside 43 deteriorates, the reaction force (pushing pressure) of the car inside seal lip 41 to the back surface side of the door glass 4 is prevented from decreasing, the car inside seal lip 41 is separated from the door glass 4, and an abnormal noise is generated. Can be prevented.

In the fifth embodiment, the car outside sub-lip 33, the car inside sub-lip 43 has a wall thickness portion 46, and the car inside seal lip 41 has a wall thickness portion 49, and the force for pressing the door glass 4 from both sides increases. Therefore, the car-outer sub-lip 33 can be formed thinner than that of the third embodiment, and the wall thickness of the car-inside sub-lip 43 can be made thinner.
