Description

TECHNICAL FIELD

[0001] The present application relates to a glass run installed to a door frame formed in a door of a vehicle such as an automobile. BACKGROUND

[0002] In a door of a vehicle, a door frame is provided at an upper portion of a door main body, a glass run in a channel shape is fitted and locked to a door frame groove portion formed in an inner peripheral edge of the door frame, an in-vehicle and out-of-vehicle glass seal portion of the glass run guides the raising and lowering of a door glass, and the in-vehicle and out-of-vehicle is sealed.

[0003] The above-described glass run is configured such that a bottom wall, an out-of-vehicle side wall on the out-of-vehicle side, and an in-vehicle side wall on the in-vehicle side constitute a basic skeleton (main body portion). Further, an out-of-vehicle side seal lip and an in-vehicle side seal lip are provided which extend from the front ends of the two side wall portions or the vicinity thereof toward the inner sides of the main body portion, respectively. Further, the main body portion of the glass run is installed to a door frame groove portion (mounting portion) provided along the inner periphery of the door frame, and the two seal lips seal the inner and outer peripheral portions of the door glass being raised and lowered by sandwiching the same. In addition, the glass run also functions to support the peripheral portion of the door glass to guide the raising and lowering of the door glass, or to suppress the shaking of the door glass.

[0004] However, in a state in which the door glass is positioned slightly below the fully closed position, the door glass is likely to be displaced in the in-vehicle direction. In the case where the automobile is driven on a poor road or the like in this state, the door glass and the seal lip are sometimes separated instantaneously, and the door glass and the seal lip come into contact again from this separated state, and in the case where separation and contact are repeated, it is possible that an abnormal noise (rattling sound) is generated due to the contact. In particular, in the case where the seal lip is degraded over time and the elastic force is reduced, the problem becomes more significant in that, in the case where the door glass is vibrated, the seal lip is easily separated from the door glass to generate an abnormal noise.

[0005] As a technique for solving the above-described problem, for example, the technique described in Patent Literature 1 is known. Regarding the configuration of the glass run of Patent Literature 1, based on Figure 1 and Figure 12 are described. Figure 1 A front door 100 on the left side of an automobile as viewed from the out-of-vehicle side is shown in a front view. A door frame 320 is formed in an upper portion of a door main 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 main body 210. A glass run 110 is installed to the inner peripheral edge of the window opening and the inside of the door main body 210 to guide the raising and lowering operation of a door glass 600.

[0006] Figure 12A vertical section showing the longitudinal frame portion of the door frame 320 ( Figure 1 (YY cross-section). Furthermore, this portion of the glass channel 110 is typically formed using an extrusion molding method. The glass channel 110 is formed in a channel shape (cross-section resembling the character "コ") with a bottom wall 200, an outer side wall 300, and an inner side wall 400 as its basic framework. An outer sealing lip 310 is formed on the outer side wall 300, contacting the surface (outer side) of the door glass 600. An inner sealing lip 410 is formed at the front end of the inner side wall 400, contacting the back (inner side) of the door glass 600. Additionally, a secondary lip 430, protruding in the opposite direction to the inner sealing lip 410, is formed between the inner sealing lip 410 and the bottom wall 200, facing outwards.

[0007] Furthermore, the inner sealing lip 410 has a protrusion 440 on its back side, and thus has a protruding surface 450 at a position that protrudes further than the general surface of the back side. When the door glass 600 is displaced from a reference position toward the inner side of the vehicle, it is configured to change from a first support state in which the front end of the secondary lip 430 extending from the inner side wall 400 slides against the protruding surface 450, and to a second support state in which the front end of the secondary lip 430 disengages from the protruding surface 450 and abuts the protrusion 440 against a portion of the secondary lip 430 that is closer to the root than the front end.

[0008] As a result, a protrusion 440 is provided on the back side of the inner sealing lip 410. The inner sealing lip 410 in this part is formed as a thick wall, and a secondary lip 430 is provided that extends from the inner side wall 400 and can abut against the protruding surface 450 of the protrusion 440. Therefore, the pressing force between the inner sealing lip 410 and the door glass 600 is increased. Even if the door glass 600 vibrates, it can prevent the inner sealing lip 410 from separating from the door glass 600 in an instant. For example, when the inner sealing lip 410 and the door glass 600 change from a separated state to a contact state, it can prevent the occurrence of abnormal noise (hitting sound) due to contact.

[0009] Furthermore, in Patent Document 1, regarding the force of the inner sealing lip 410 pressing against the door glass 600 in the first and second support states, i.e. the reaction force of the inner sealing lip 410 against the door glass 600, it is stated that "the more the door glass moves significantly from the reference position towards the inner side of the vehicle, the stronger the door glass is pressed against the inner sealing lip, and the greater the reaction force of the inner sealing lip becomes. However, when changing from the first support state to the second support state, the support of the front end of the protruding face to the secondary lip is released, thus temporarily suppressing the increase in the reaction force of the inner sealing lip." (paragraph 0014) shows that the force in the first support state is greater than that in the second support state.

[0010] Patent Literature 1: Japanese Patent Application Laid-Open (JP A) No. 2018-149984 SUMMARY

[0011] However, in the technology of Patent Literature 1 described above, as described above, the protruding portion 440 in which the back surface of the in-vehicle-side sealing lip 410 has the protruding surface 450 is the extrusion-molded portion. The cross-sectional shape of the extrusion-molded portion of the glass run is generally not changed. Therefore, in Patent Literature 1, the protruding portion 440 is formed in the entire longitudinal edge portion, and at times the protruding portion 440 comes into abutment with the sub-lip 430 when the door glass 600 is in sliding contact, and thus the reaction force from the in-vehicle-side sealing lip 410 against the door glass 600 increases, and as a result, the problem that the sliding property is deteriorated remains. In addition, the protruding portion 440 is formed in the entire longitudinal edge portion, and thus the weight of the glass run increases.

[0012] Therefore, the present application provides a glass run that does not adversely affect the sliding property of the door glass and can suppress the weight increase as much as possible, in which a mold-molded portion that connects extrusion-molded portions is formed in a configuration that increases the reaction force against the door glass, and can prevent the generation of abnormal noise in a state in which the door glass is positioned at a position slightly lower than the fully closed position, including when deteriorated over time.

[0013] In order to solve the above-described problems, the present application of Technical Solution 1 is a glass run that has a base wall, an out-vehicle-side wall, and an in-vehicle-side wall as a basic skeleton, and has an out-vehicle-side sealing lip formed at or near the front end of the out-vehicle-side wall and an in-vehicle-side sealing lip formed at or near the front end of the in-vehicle-side wall, which is installed in a door frame groove portion formed in a door frame, characterized in that, in a mold-molded portion at the time of mold-molding that connects extrusion-molded portions, or a region that is continuous with the mold-molded portion at the time of mold-molding and the extrusion-molded portions that connect the mold-molded portion, at least with respect to a longitudinal edge portion corresponding to one of the longitudinal edge portions of the door glass in the front and rear of the vehicle, a sealing-lip protruding portion that protrudes toward the in-vehicle-side wall side is formed at or near a sealing-lip front end portion of a general surface of the in-vehicle-side wall side of the in-vehicle-side sealing lip, and a sub-lip that protrudes obliquely toward the in-vehicle-side surface direction of the in-vehicle-side sealing lip is formed between the in-vehicle-side sealing lip of the in-vehicle-side wall and the base wall, and the sealing-lip protruding portion comes into abutment with the sub-lip at the time of sliding contact with the door glass.

[0014] When the door glass is vibrated in the inside and outside directions of the vehicle while being positioned slightly lower than the fully closed position, the door glass repeatedly separates from and contacts the inside seal lip, and in most cases, a region in which an abnormal noise (a knocking sound) is generated due to the contact is observed at a die molding portion at the time of molding the mold-molding portion or the mold-molding portion and the vicinity thereof, which connects the extrusion-molded portions. In the present invention of Technical Solution 1, in a region that is continuous with respect to the die molding portion at the time of molding and the extrusion-molded portion that connects the die molding portion, a seal lip front end portion whose general surface is on the inside wall side of the inside seal lip is formed, or a seal lip protrusion that protrudes toward the inside wall side from the vicinity thereof is formed, and the seal lip protrusion abuts against the sub-lip, so that in the case where the door glass is displaced toward the inside, the inside seal lip strongly presses the sub-lip toward the inside wall side. As a result, it is possible to prevent the inside seal lip from separating from the door glass to generate an abnormal noise, using the reaction force (pressing force) from the sub-lip toward the back surface side of the inside seal lip.

[0015] In addition, the seal lip protrusion is formed at the die molding portion at the time of molding or the region that is continuous with respect to the die molding portion at the time of molding and the extrusion-molded portion that connects the die molding portion, so that compared to the case where the seal lip protrusion is formed at the entire extrusion-molded portion, it is possible to suppress an increase in the weight of the entire glass runner.

[0016] Further, the above configuration is formed at the die molding portion at the time of molding or the region that is continuous with respect to the die molding portion at the time of molding and the extrusion-molded portion that connects the die molding portion, so that it does not affect the slidability of the extrusion-molded portion.

[0017] In addition, at the time of extrusion molding, it is not necessary to consider / research the influence on other functions that the extrusion-molded portion has, which accompanies the formation of the seal lip protrusion and the sub-lip in the extrusion-molded portion, so that it is possible to achieve a reduction in development time.

[0018] Further, the "region that is continuous with respect to the die molding portion at the time of molding and the extrusion-molded portion that connects the die molding portion" means that in the case where the extrusion-molded portions are connected in the molding, the molding die mostly covers the die molding portion and the extrusion-molded portion, and at the time of molding, the cross-sectional shape of the die molding is reflected not only to the die molding portion but also to the region of the extrusion-molded portion that connects the die molding portion.

[0019] The present invention of Technical Solution 2 is based on the invention of Technical Solution 1, and a side wall protrusion that protrudes toward the outside is formed between the inside seal lip on the outside side of the inside wall and the bottom wall, and the sub-lip is formed so as to be obliquely protruded toward the inside of the inside seal lip from the side wall protrusion.

[0020] Not only the inboard seal lip but also the sub-lip is deteriorated over time. Therefore, the reaction force (pressing force) toward the back surface side of the inboard seal lip decreases due to the deterioration of the sub-lip, and there is a concern that the inboard seal lip is separated from the door glass to cause a problem of generating a noise again.

[0021] In the present application of the technical solution 2, the side wall protrusion protruding toward the outboard side is formed between the inboard seal lip of the outboard side surface of the inboard side wall and the bottom wall, and the sub-lip is formed to be obliquely protruded toward the inboard side surface direction of the inboard seal lip from the side wall protrusion, so that the length of the sub-lip can be shortened, and even when the sub-lip is deteriorated over time, the reaction force (pressing force) toward the back surface side of the inboard seal lip can be suppressed from decreasing, and the inboard seal lip can be prevented from being separated from the door glass to cause a problem of generating a noise again.

[0022] In addition, the side wall protrusion is formed on the outboard side between the inboard seal lip of the inboard side wall and the bottom wall, so that compared with the case where the entire inboard side wall is formed thick, the weight increase of the entire glass runner can be suppressed as much as possible.

[0023] Further, the above configuration is formed in a mold molding portion at the time of molding a mold that connects the extrusion-molded portions, or a region continuous with respect to the mold molding portion at the time of molding a mold and the extrusion-molded portion connected to the mold molding portion, so that the sliding property of the extrusion-molded portion is not affected. In addition, at the time of extrusion molding, it is not necessary to consider / research the influence on other functions that the extrusion-molded portion has, which is accompanied by forming the seal lip protrusion, the side wall protrusion, and the sub-lip in the extrusion-molded portion, so that the development time can be shortened.

[0024] The present application of the technical solution 3 has the following structure based on the application of the technical solution 1 or the technical solution 2, that is, the protrusion surface is formed in the seal lip protrusion, the protrusion surface protrusion protruding toward the inboard side wall side is formed on the inboard seal lip on the seal lip front end portion side of the protrusion surface, and in the case where the door glass is displaced toward the inboard side, the inboard seal lip and the sub-lip have the following structure, that is, the first support state in which the sub-lip front end portion of the sub-lip abuts against the protrusion surface of the inboard seal lip protrusion except for the protrusion surface protrusion, and the second support state in which the outboard side surface of the sub-lip abuts against the protrusion surface protrusion can be changed.

[0025] In the present application of Technical Solution 3, the convex portion of the sealing lip is formed with a convex surface, and a convex surface convex portion protruding toward the inner side wall side is formed on the inner side of the vehicle of the convex surface of the inner side sealing lip on the side of the front end portion of the inner side sealing lip. In the case where the door glass is displaced toward the inner side of the vehicle, the first support state is changed in which the front end portion of the secondary lip abuts against the convex surface of the inner side sealing lip convex portion except for the convex surface convex portion, and thus the convex surface presses the secondary lip toward the inner side of the vehicle. As a result, the reaction force (pressing force) from the secondary lip toward the back surface side of the inner side sealing lip via the sealing lip convex portion can be used to prevent the inner side sealing lip from separating from the door glass to generate an abnormal noise.

[0026] In addition, in the case where the door glass is further displaced toward the inner side of the vehicle, the second support state is changed in which the outer side of the secondary lip abuts against the convex surface convex portion, and thus the force by which the secondary lip is pressed toward the inner side of the vehicle is stronger than that in the first support state. As a result, the reaction force (pressing force) from the secondary lip toward the back surface side of the inner side sealing lip can be used to prevent the inner side sealing lip from separating from the door glass to generate an abnormal noise.

[0027] The present application of Technical Solution 4 is based on the application of Technical Solution 1 or Technical Solution 2, and the convex surface of the sealing lip convex portion is formed with a connecting surface between the general surface of the inner side sealing lip. In the case where the door glass is displaced toward the inner side of the vehicle, the inner side sealing lip and the secondary lip have a structure that can be changed to the first support state in which the front end portion of the secondary lip or the outer side of the secondary lip abuts against the connecting surface and the corner portion of the convex surface, and the second support state in which the outer side of the secondary lip abuts against the convex surface.

[0028] In the present application of Technical Solution 4, the convex surface of the sealing lip convex portion is formed with a connecting surface between the general surface of the inner side sealing lip. In the case where the door glass is displaced toward the inner side of the vehicle, the inner side sealing lip and the secondary lip are changed to the first support state in which the front end portion of the secondary lip or the outer side of the secondary lip abuts against the connecting surface and the corner portion of the convex surface, and thus the connecting surface and the corner portion of the convex surface press the secondary lip toward the inner side of the vehicle. As a result, the reaction force (pressing force) from the secondary lip toward the back surface side of the inner side sealing lip via the sealing lip convex portion can be used to prevent the inner side sealing lip from separating from the door glass to generate an abnormal noise.

[0029] In addition, in the case where the door glass is further displaced toward the inner side of the vehicle, the second support state is changed in which the outer side of the secondary lip abuts against the convex surface, and thus the force by which the secondary lip is pressed toward the inner side of the vehicle is stronger than that in the first support state. As a result, the reaction force (pressing force) from the secondary lip toward the back surface side of the inner side sealing lip can be used to prevent the inner side sealing lip from separating from the door glass to generate an abnormal noise.

[0030] The application of technical solution 5 is based on the application of technical solution 1 or technical solution 2, and in the case that the door glass is displaced to the inside of the vehicle, the structure between the inside sealing lip and the sub-lip is changed to the first supporting state in which the front end of the sub-lip abuts against the general surface of the inside sealing lip, and the second supporting state in which the front end of the sub-lip abuts against the general surface of the inside sealing lip and the outside surface of the sub-lip abuts against the sealing lip convex part.

[0031] In the application of technical solution 5, in the case that the door glass is displaced to the inside of the vehicle, the structure between the inside sealing lip and the sub-lip is changed to the first supporting state in which the front end of the sub-lip abuts against the general surface of the inside sealing lip, so that the general surface of the inside sealing lip presses the sub-lip to the inside of the vehicle. As a result, the inside sealing lip can be prevented from separating from the door glass to produce an abnormal sound by using the reaction force (pressing force) from the sub-lip to the back surface side of the inside sealing lip.

[0032] In addition, in the case that the door glass is further displaced to the inside of the vehicle, the structure is changed to the second supporting state in which the front end of the sub-lip abuts against the general surface of the inside sealing lip and the outside surface of the sub-lip abuts against the sealing lip convex part, so that the force pressing the sub-lip to the inside wall side is stronger than that in the first supporting state. As a result, the inside sealing lip can be prevented from separating from the door glass to produce an abnormal sound by using the reaction force (pressing force) from the sub-lip to the back surface side of the inside sealing lip.

[0033] The application of technical solution 6 is a glass runner which takes a bottom wall, an outside wall and an inside wall as the basic framework, and has an outside sealing lip formed at the front end of the outside wall or in the vicinity thereof, and an inside sealing lip formed at the front end of the inside wall or in the vicinity thereof, which is installed in the door frame groove part formed in the door frame. The feature is that a sealing lip convex part protruding to the inside wall side is formed at the sealing lip front end of the general surface of the inside wall side of the inside sealing lip or in the vicinity thereof with respect to the longitudinal edge part corresponding to one of the longitudinal edge parts in the front and back of the vehicle of the door glass, at least about the longitudinal edge part, and a wall convex part protruding to the outside is formed between the inside sealing lip of the outside surface of the inside wall and the bottom wall, and the sealing lip convex part and the wall convex part abut against each other when the door glass is in sliding contact.

[0034] In the present application of Technical Solution 6, a sealing lip protruding toward the inner side wall side is formed at the front end of the general surface of the inner side wall side of the inner side sealing lip, or in the vicinity thereof, and a side wall protruding toward the outer side of the inner side sealing lip and the bottom wall of the inner side wall is formed, and the sealing lip protruding portion and the side wall protruding portion abut against each other when the door glass slides in contact, so that a sub-lip is not formed, and the sealing lip protruding portion and the side wall protruding portion abut against each other when the door glass slides in contact, so that the sealing lip is strongly pressed toward the door glass side in the case where the door glass is displaced toward the inner side. As a result, the reaction force (pressing force) of the inner side sealing lip against the door glass is increased, and the inner side sealing lip is prevented from being separated from the door glass to produce a noise.

[0035] In addition, the above configuration is formed in a mold molding portion at the time of molding a mold that connects the extrusion-molded portions, or a region continuous with respect to the mold molding portion at the time of molding a mold and the extrusion-molded portion connected to the mold molding portion, so that the sliding property of the extrusion-molded portion is not affected.

[0036] In addition, the sealing lip protruding portion and the side wall protruding portion are formed in a region continuous with respect to the mold molding portion at the time of molding a mold and the extrusion-molded portion connected to the mold molding portion, so that the weight of the entire glass runner can be suppressed from increasing compared to the case where the sealing lip protruding portion and the side wall protruding portion are formed in the entire extrusion-molded portion.

[0037] In addition, at the time of extrusion molding, it is not necessary to consider / research the influence on other functions that the extrusion-molded portion has, which is accompanied by the formation of the sealing lip protruding portion and the side wall protruding portion in the extrusion-molded portion, so that the development time can be shortened.

[0038] Effects of the Invention

[0039] In the region continuous with respect to the mold molding portion at the time of molding a mold and the extrusion-molded portion connected to the mold molding portion, the inner side sealing lip is formed with a sealing lip front end of a general surface of the inner side wall side thereof, or a sealing lip protruding portion protruding toward the inner side wall side from the vicinity thereof, and the sealing lip protruding portion abuts against the sub-lip, so that the sub-lip is strongly pressed toward the inner side wall side in the case where the door glass is displaced toward the inner side. As a result, the reaction force (pressing force) from the sub-lip toward the back surface side of the inner side sealing lip can be used to prevent the inner side sealing lip from being separated from the door glass to produce a noise.

[0040] In addition, the sealing lip protruding portion is formed in a mold molding portion at the time of molding a mold, or a region continuous with respect to the mold molding portion at the time of molding a mold and the extrusion-molded portion connected to the mold molding portion, so that the weight of the entire glass runner can be suppressed from increasing compared to the case where the sealing lip protruding portion is formed in the entire extrusion-molded portion.

[0041] Further, the above configuration is formed in a die molding portion at the time of die molding or a region continuous with respect to the die molding portion at the time of die molding and an extrusion-molded member connected to the die molding portion, and thus does not affect slidability of the extrusion-molded portion.

[0042] Further, at the time of extrusion molding, it is not necessary to consider / research an influence on other functions of the extrusion-molded member accompanying formation of the seal lip protrusion and the sub-lip in the extrusion-molded member, and shortening of development time can be achieved.

[0055] The first embodiment of the present application will be explained based on Figures 1 to 3 The first embodiment of the present application will be explained based on Figure 1 is a front view of the front door 1 on the left side of the vehicle as viewed from the outside of the vehicle. A door frame 3 is mounted on the upper portion of a door main 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 main body 2. A glass run channel 10 is mounted on the inner peripheral edge of the window opening and the inside of the door main body 2, and guides the up-and-down movement of a door glass 4. Further, the present application can be applied not only to the front door 1 on the left side, but also to the front door on the right side, the rear doors on the left and right sides, and the sliding door for which the door glass is raised and lowered.

[0056] Figure 2 (a) is a cross-sectional view of the glass run channel of the first embodiment of the present application, and is a cross-sectional view corresponding to the A-A line of (b) of Figure 1 ​​​​​A front view of the glass run 10 simplified from the outside of the vehicle. The glass run 10 is composed of a first extrusion molded portion 11 corresponding to the horizontal frame portion of the door frame 3, a second extrusion molded portion 12 (front side vertical edge portion) corresponding to the front side vertical frame portion of the front door 1, and a third extrusion molded portion 13 (rear side vertical edge portion) corresponding to the rear side vertical frame portion. The front end portion of the first extrusion molded portion 11 is connected to the upper end portion of the second extrusion molded portion 12 using a first mold formed portion 14. In addition, the rear end portion of the first extrusion molded portion 11 is connected to the upper end portion of the third extrusion molded portion 13 using a second mold formed portion 15.

[0057] Here, a case where the vehicle is driven on a bad road or the like, and the door glass 4 vibrates in the vehicle interior-exterior direction in a state where the door glass 4 is located slightly below the fully closed position between the door glass 4 and the glass run 10 is described. In the case where the door glass 4 is fully closed by being raised to the uppermost position, the door glass 4 is supported from three directions by abutting against the first extrusion molded portion 11 of the glass run 10, the second extrusion molded portion 12 corresponding to the front side vertical frame portion of the front door 1, and the third extrusion molded portion 13 corresponding to the rear side vertical frame portion. Therefore, even when the vehicle is driven on a bad road or the like, the door glass 4 does not vibrate in the vehicle interior-exterior direction.

[0058] If the door glass 4 is slightly lowered so that the abutment of the door glass 4 against the first extrusion molded portion 11 is released, the door glass 4 is mainly supported in two directions in the vertical direction by the abutment of the door glass 4 against the first mold formed portion 14 of the glass run 10 corresponding to the front side vertical frame portion of the front door 1, the second extrusion molded portion 12, and the second mold formed portion 15 of the glass run 10 corresponding to the rear side vertical frame portion, and the third extrusion molded portion 13. At this time, when the vehicle is driven on a bad road or the like, the door glass 4 sometimes vibrates in the vehicle interior-exterior direction to cause the above-described abnormal noise.

[0059] Further, if the door glass 4 is further lowered, depending on the relationship between the door glass 4 and the glass run 10, the support in two directions against the second extrusion molded portion 12 corresponding to the front side vertical frame portion of the front door 1, and the third extrusion molded portion 13 corresponding to the rear side vertical frame portion is maintained, the door glass 4 is mounted to the beltline 6 of the front door 1 (for example, supported by the beltline weather strip), and is thus substantially supported in three directions. Therefore, at this stage, even when the vehicle is driven on a bad road or the like, the vibration of the door glass 4 in the vehicle interior-exterior direction is extremely small. Figure 1

[0060] Figure 3 is a front view of the glass run 10 simplified from the outside of the vehicle. The glass run 10 is composed of a first extrusion molded portion 11 corresponding to the horizontal frame portion of the door frame 3, a second extrusion molded portion 12 (front side vertical edge portion) corresponding to the front side vertical frame portion of the front door 1, and a third extrusion molded portion 13 (rear side vertical edge portion) corresponding to the rear side vertical frame portion. The front end portion of the first extrusion molded portion 11 is connected to the upper end portion of the second extrusion molded portion 12 using a first mold formed portion 14. In addition, the rear end portion of the first extrusion molded portion 11 is connected to the upper end portion of the third extrusion molded portion 13 using a second mold formed portion 15. Figure 2 ​(b) A-A line corresponds to a sectional view showing the vicinity of the joint portion of the second mold forming portion 15 with respect to the third extrusion forming portion 13 corresponding to the longitudinal frame portion of the rear side. The glass run 10 is formed in a channel shape (sectional shape is approximately "コ" shape) with a bottom wall 20, an outer side wall 30, and an inner side wall 40 as a basic skeleton.

[0061] The bottom wall 20 is formed in an approximately plate shape, and a plurality of bottom wall recesses 22 are formed continuously and in parallel in the length direction on the inner surface (the abutting side with the door glass 4) of the bottom wall 20. Further, an abutting lip 23 formed on the door frame groove portion 5 side abuts against the door frame groove portion 5.

[0062] On the outer side of the outer side wall 30, a first outer side retaining lip 33 and a second outer side retaining lip 34 that are latched to the door frame groove portion 5 are formed in the vicinity of the joint portion with the bottom wall 20 and in the direction of the front end portion of the outer side wall 30, and the curved door frame groove portion 5 is retained by the first outer side retaining lip 33 and the second outer side retaining lip 34.

[0063] The outer side seal lip 31 that contacts the door glass 4 is formed on the inner side of the outer side wall 30 toward the bottom wall 20 side, and the outer side cover lip 32 is formed on the front end portion of the outer side wall 30 toward the opposite side of the outer side seal lip 31. The outer side cover lip 32 and the outer side seal lip 31 together abut against the outer side surface of the door glass 4, and can prevent the intrusion of rain, dust, and noise to improve the sealing property.

[0064] Further, at the root portion of the outer side cover lip 32, a latching portion 35 is formed toward the outer side to fix the end portion of the pillar garnish 7 and seal the gap between the pillar garnish 7 and the surface of the door glass 4.

[0065] On the other hand, the inner side seal lip 41 is formed on the outer side of the inner side wall 40, which is provided extending toward the outer side and the bottom wall 20 side from the front end portion of the inner side wall 40 and the bottom wall 20, and the side surface on the outer side is in sliding contact with the door glass 4. Further, on the root portion 41b side of the inner side seal lip 41 than the seal lip front end portion 41a of the inner side seal lip 41, a seal lip protrusion 47 is formed protruding from the general surface 42 on the inner side wall 40 side of the inner side seal lip 41.

[0066] Further, a sub-lip 43 protruding in the opposite direction to the inner side seal lip 41 is formed toward the outer side between the inner side seal lip 41 of the inner side wall 40 and the bottom wall 20. The thickness of the sub-lip 43 is substantially the same, and the front end portion is formed in an arc shape. Further, it can also be a shape in which the thickness is different, and the inner side wall 40 side is thicker and tends to be thin toward the front end.

[0067] Further, on the inner side of the inner side wall 40, an inner side first holding lip 44 and an inner side second holding lip 45 which are engaged with the inner side of the curved portion of the door frame groove portion 5 in the vicinity of the joint portion with the bottom wall 20 are formed, and an abutting lip 49 is formed between the two holding lips 44, 45. The inner side wall 40 is held to the curved door frame groove portion 5 by the two holding lips 44, 45 and the abutting lip 49.

[0068] Further, on the inner side of the front end of the inner side wall 40, on the opposite side (inner side) of the inner side sealing lip 41, an inner side covering lip 48 is formed. The inner side covering lip 48 abuts against the front end of the door frame groove portion 5, and can prevent the intrusion of rain, dust, and noise to improve the sealing property.

[0069] Further, in the Figure 3 , the sealing lip protrusion 47 is depicted in a different display manner from the inner side sealing lip 41 and the sub-lip 43, which is to emphasize the existence of the above-mentioned members, and does not mean that it is formed of a different material, for example. Therefore, it can be formed of the same material as the inner side sealing lip 41, and even if it is the same material, the hardness can be different, and of course, it can be formed of a different material.

[0070] Figure 3 An abutting state of the inner side sealing lip 41 and the sub-lip 43 when the door glass 4 is slightly lowered and displaced to the inner side is shown. According to the Figure 3 It is clear that the sealing lip protrusion 47 abuts in a manner to press the sub-lip 43 to the inner side.

[0071] As a result, the sub-lip 43 generates a reaction force toward the outer side, and the reaction force is pressed to the inner side of the door glass 4 via the inner side sealing lip 41 including the sealing lip protrusion 47, and thus the reaction force against the door glass 4 is increased, and the inner side sealing lip can be prevented from being separated from the door glass to generate a noise.

[0072] Further, in the case where the door glass 4 is displaced to the inner side further than the Figure 3 , the sub-lip 43 is further flexibly deformed to the inner side, and the reaction force against the inner side sealing lip 41 is increased.

[0073] Next, a second embodiment will be described based on Figures 4 to 6 The second embodiment will be described. As shown in Figure 4 The outer side sealing lip 31 which contacts the door glass 4 is formed on the inner side of the outer side wall 30 toward the bottom wall 20 side, and the outer side covering lip 32 is formed on the front end portion of the outer side wall 30 toward the opposite side of the outer side sealing lip 31.

[0074] Further, on the vehicle exterior side of the vehicle exterior side wall 30, a vehicle exterior side first holding rib 36 and a vehicle exterior side second holding rib 37 are formed which are engaged with the vehicle exterior side of the curved portion of the door frame groove portion 5 having a circular arc shape. Also, at the root portions of the vehicle exterior side seal lip 31 and the vehicle exterior side cover lip 32, an engagement portion 35 is formed toward the vehicle exterior side and is fixed to the end portion of the door frame groove portion 5.

[0075] On the other hand, the vehicle interior side seal lip 41 which contacts the door glass 4 is formed toward the bottom wall 20 side at the front end of the vehicle interior side wall 40. Further, on the vehicle interior side of the vehicle interior side wall 40, a vehicle interior side first holding lip 44 and a vehicle interior side second holding lip 45 are formed which are engaged with the curved portion of the door frame groove portion 5 having a circular arc shape in the vicinity of the joint portion with the bottom wall 20.

[0076] Further, on the vehicle interior side of the vehicle interior side wall 40, a vehicle interior side first holding lip 44 and a vehicle interior side second holding lip 45 are formed which are engaged with the curved portion of the door frame groove portion 5 having a circular arc shape in the vicinity of the joint portion with the bottom wall 20.

[0077] Further, on the vehicle interior side of the vehicle interior side wall 40, a vehicle interior side first holding lip 44 and a vehicle interior side second holding lip 45 are formed which are engaged with the curved portion of the door frame groove portion 5 having a circular arc shape in the vicinity of the joint portion with the bottom wall 20.

[0078] Further, on the vehicle interior side of the vehicle interior side wall 40, a vehicle interior side first holding lip 44 and a vehicle interior side second holding lip 45 are formed which are engaged with the curved portion of the door frame groove portion 5 having a circular arc shape in the vicinity of the joint portion with the bottom wall 20.

[0079] Further, on the vehicle interior side of the vehicle interior side wall 40, a vehicle interior side first holding lip 44 and a vehicle interior side second holding lip 45 are formed which are engaged with the curved portion of the door frame groove portion 5 having a circular arc shape in the vicinity of the joint portion with the bottom wall 20. Figure 4 Further, on the vehicle interior side of the vehicle interior side wall 40, a vehicle interior side first holding lip 44 and a vehicle interior side second holding lip 45 are formed which are engaged with the curved portion of the door frame groove portion 5 having a circular arc shape in the vicinity of the joint portion with the bottom wall 20. Figure 4 Further, on the vehicle interior side of the vehicle interior side wall 40, a vehicle interior side first holding lip 44 and a vehicle interior side second holding lip 45 are formed which are engaged with the curved portion of the door frame groove portion 5 having a circular arc shape in the vicinity of the joint portion with the bottom wall 20.

[0080] In addition, in Figure 4 Figure 4 In the following drawings as well, the seal lip protrusion 47 and the side wall protrusion 46 are depicted in a different display manner from the inboard seal lip 41, the inboard side wall 40, and the sub-lip 43, but this is in order to highlight the presence of the above-mentioned members, for example, and does not represent that they are formed of different materials. Therefore, they can be formed of the same material as the inboard seal lip 41 and the inboard side wall 40, even if the same material, for example, the hardness can be different, and of course, they can be formed of different materials.

[0081] An inboard cover lip 48 is formed on the opposite side (inboard side) of the inboard seal lip 41 at the front end of the inboard side wall 40. In addition, in the drawings, the inboard cover lip 48 is depicted as a continuous shape with respect to the inboard seal lip 41, but is not limited thereto.

[0082] Figure 4 The abutment state of the inboard seal lip 41 and the sub-lip 43 in a first support state in which the door glass 4 is slightly lowered and displaced toward the inboard side is shown. In addition, the abutment state of the inboard seal lip 41 and the sub-lip 43 in the first support state is almost unchanged from the abutment state of the inboard seal lip 41 and the sub-lip 43 when the door glass 4 is completely closed.

[0083] According to Figure 4 As is clear, in the first support state, the sub-lip front end portion 43a of the sub-lip 43 abuts against the protruding surface 47a of the seal lip protrusion 47 of the inboard seal lip 41, and the sub-lip 43 is pressed toward the inboard side wall 40 and deformed. As a result, a reaction force is generated in the sub-lip 43, which presses the inboard side of the door glass 4 toward the outboard side via the inboard seal lip 41 including the seal lip protrusion 47.

[0084] As described above, the sub-lip 43 is formed so as to protrude obliquely from the short side of the side wall protrusion 46 of the approximate trapezoidal shape toward the inboard side of the inboard seal lip 41, and the length thereof is formed to be shorter than the current, so that even when the sub-lip 43 deteriorates over time, the reaction force (pressing force) toward the back side of the inboard seal lip 41 can be suppressed from decreasing, and the inboard seal lip 41 can be prevented from separating from the door glass 4 to generate an abnormal noise again.

[0085] Figure 5 The abutment state of the seal lip protrusion 47 and the sub-lip 43 in a second support state in which the door glass 4 is slightly lowered from Figure 4 the state, and the door glass 4 is further displaced toward the inboard side. According to Figure 5 ​As is clear, if the door glass 4 is displaced further toward the inside of the vehicle, the inside-of-vehicle seal lip 41 also deforms toward the inside of the vehicle in follow-up to the door glass 4, and the sub-lip front end portion 43a of the sub-lip 43 causes the projection face 47a of the seal-lip projection 47 to slide toward the root portion 41b side of the inside-of-vehicle seal lip 41.

[0086] With the deformation of the inside-of-vehicle seal lip 41, the projection-face projection 47b, which is formed on the projection face 47a toward the inside-of-vehicle seal lip 41 on the seal-lip front end portion 41a side, projects toward the inside-of-vehicle side wall side, and abuts against the outside-of-vehicle face of the sub-lip 43, pressing the sub-lip 43 further toward the inside-of-vehicle side wall 40 and deforming it. As a result, the pressing load against the sub-lip 43 increases.

[0087] Figure 6 is a graph showing the relationship between the displacement of the door glass 4 of the glass run channel 10 and the load toward the inside of the vehicle of the door glass 4. Figure 6 The A region in is the first support state, and the B region is the second support state. According to Figure 6 As is clear, the reaction force against the door glass 4 is greater in the second support state than in the first support state.

[0088] Therefore, the displacement of the door glass 4 toward the inside of the vehicle and the pressing load of the door glass 4 toward the inside of the vehicle, which are caused by the reaction force of the sub-lip 43, are generated according to the first support state, which is achieved by the abutment of the sub-lip 43 against the projection face 47a of the seal-lip projection 47, and the second support state, which is achieved by the abutment of the sub-lip 43 against the projection-face projection 47b of the seal-lip projection 47, and thus even in the case where the door glass 4 vibrates in a state where the door glass 4 is positioned slightly below the fully closed position, i.e., in a state where the door glass 4 is displaced toward the inside of the vehicle, and the vehicle is driven on a poor road or the like, the inside-of-vehicle seal lip 41 can be prevented from separating from the door glass 4 and the generation of an abnormal sound can be prevented.

[0089] Further, on the outside-of-vehicle face between the root portion 41b of the inside-of-vehicle seal lip 41 of the inside-of-vehicle side wall 40 and the bottom wall 20, a side wall projection 46, which is approximately trapezoidal in shape with a short side on the outside-of-vehicle side and projects toward the outside of the vehicle, is formed, and the sub-lip 43 is formed so as to project obliquely toward the inside-of-vehicle face direction of the inside-of-vehicle seal lip 41 from the side wall projection 46, and thus even in the case where the sub-lip 43 deteriorates over time, the reaction force (pressing force) toward the back face side of the inside-of-vehicle seal lip 41 can be suppressed from decreasing, and the door glass 4 can be prevented from separating from the door glass 4 and the generation of an abnormal sound can be prevented.

[0090] Next, based on Figure 7 and Figure 8 A third embodiment will be described. Regarding the differences between the present third embodiment and the above-described first embodiment, first, the outside-of-vehicle side wall 30 side is the same as in the first embodiment.

[0091] Second, on the inner side wall 40 side, a second inner side seal lip 50 is formed at a position further forward than the inner side seal lip 41, in the same direction as the inner side seal lip 41. The second inner side seal lip 50 doubles the sealing of the inner side surface of the door glass 4 with the inner side seal lip 41.

[0092] Third, a seal lip protrusion 47 is formed on the seal lip front end portion 41a of the inner side seal lip 41. Also, the protrusion face 47a of the seal lip protrusion 47 is not formed with a protrusion face protrusion 47b, but this can also be formed.

[0093] Here, the first and second differences relate to changes in the basic skeleton of the glass runner 10, and are not directly related to the present application, so the third difference will be explained in detail below.

[0094] Figure 7 The abutment state of the inner side seal lip 41 and the sub-lip 43 in the first support state when the door glass 4 is slightly lowered and displaced toward the inner side. The sub-lip front end portion 43a of the sub-lip 43 abuts the joint face 47c of the seal lip protrusion 47 and the corner of the protrusion face 47a of the inner side seal lip 41, and the sub-lip 43 is pressed toward the inner side wall 40 and deformed. As a result, a reaction force is generated in the sub-lip 43, which presses the inner side surface of the door glass 4 toward the outer side via the inner side seal lip 41, including the seal lip protrusion 47.

[0095] If the door glass 4 is further displaced toward the inner side from the state of Figure 7 , the inner side seal lip 41 also deforms toward the inner side following the door glass 4, and the sub-lip front end portion 43a of the sub-lip 43 slides the joint face 47c of the seal lip protrusion 47 and the corner of the protrusion face 47a toward the root portion 41b of the inner side seal lip 41.

[0096] Figure 8 The abutment state of the inner side seal lip 41 and the sub-lip 43 in the second support state when the door glass 4 is further displaced toward the inner side from the state of Figure 7 being further slightly lowered, etc. The outer side surface of the sub-lip 43 abuts the protrusion face 47a of the seal lip protrusion 47, and the sub-lip 43 is further deformed by being pressed toward the inner side wall 40. As a result, the pressing load on the sub-lip 43 is increased as in the case of the second embodiment.

[0097] Therefore, the displacement of the door glass 4 toward the inside of the vehicle and the pressing load of the door glass 4 toward the inside of the vehicle caused by the reaction force of the sub-lip 43 are generated according to the first support state achieved by the abutment of the connecting surface 47c of the sealing-lip protrusion 47 and the corner of the protruding surface 47a of the sealing-lip protrusion 47 and the second support state achieved by the abutment of the sub-lip 43 and the protruding surface 47a of the sealing-lip protrusion 47, and thus in the case where the door glass 4 vibrates in the state where the door glass 4 is located at a position slightly lower than the fully closed position, that is, in the state where the door glass 4 is displaced toward the inside of the vehicle, the inside-of-vehicle sealing-lip 41 can be prevented from being separated from the door glass 4 to prevent the generation of abnormal noise.

[0098] In addition, on the outside-of-vehicle side between the root 41b of the inside-of-vehicle sealing-lip 41 of the inside-of-vehicle side wall 40 and the bottom wall 20, a side-wall protrusion 46 having a trapezoidal shape with a short side on the outside-of-vehicle side and protruding toward the outside of the vehicle is formed, and the sub-lip 43 is formed so as to protrude obliquely toward the inside-of-vehicle side of the inside-of-vehicle sealing-lip 41 from the side-wall protrusion 46, and thus the length of the sub-lip 43 is shortened compared to the present, and even in the case where the sub-lip 43 deteriorates over time, the reaction force (pressing force) toward the back side of the inside-of-vehicle sealing-lip 41 can be suppressed from decreasing, and the inside-of-vehicle sealing-lip 41 can be prevented from being separated from the door glass 4 to prevent the generation of abnormal noise.

[0099] Next, based on Figure 9 and Figure 10 A fourth embodiment will be described. The fourth embodiment is different from the above-described third embodiment in that the sealing-lip protrusion 47 does not have a planar protruding surface 47a but has a triangular shape. In addition, the sealing-lip protrusion 47 can have an arc shape.

[0100] Figure 9 An abutment state of the inside-of-vehicle sealing-lip 41 and the sub-lip 43 in the first support state in which the door glass 4 is slightly lowered and displaced toward the inside of the vehicle is shown. According to the first support state, the sub-lip front end 43a of the sub-lip 43 abuts against the general surface 42 of the inside-of-vehicle sealing-lip 41, and the sub-lip 43 is pressed toward the inside-of-vehicle side wall 40 and deformed. Figure 9 It is clear that in the first support state, the sub-lip front end 43a of the sub-lip 43 abuts against the general surface 42 of the inside-of-vehicle sealing-lip 41, and the sub-lip 43 is pressed toward the inside-of-vehicle side wall 40 and deformed. As a result, the reaction force is generated in the sub-lip 43, and the reaction force presses the inside-of-vehicle side of the door glass 4 toward the outside of the vehicle via the inside-of-vehicle sealing-lip 41.

[0101] Figure 10 An abutment state of the inside-of-vehicle sealing-lip 41 and the sub-lip 43 in the second support state in which the door glass 4 is displaced toward the inside of the vehicle is shown. According to the second support state, the sub-lip 43 abuts against the protruding surface 47a of the sealing-lip protrusion 47, and the sub-lip 43 is pressed toward the inside-of-vehicle side wall 40 and deformed. Figure 9the state further slightly decreases, and so on, the inboard side sealing lip 41 of the 2nd support state and the sub-lip 43 further displace toward the inboard side. If the door glass 4 further displaces toward the inboard side, the inboard side sealing lip 41 also deforms toward the inboard side following the door glass 4, and the sub-lip front end portion 43a of the sub-lip 43 slides the general face 42 of the inboard side sealing lip 41 toward the root portion 41b side of the inboard side sealing lip 41.

[0102] In the 2nd support state, the outboard side face of the sub-lip 43 is in abutment with the sealing lip convex portion 47, and the sub-lip 43 is further deformed by being pressed toward the inboard side side wall 40 direction. As a result, the pressing load against the sub-lip 43 increases as in the case of the 2nd embodiment.

[0103] Therefore, the displacement of the door glass 4 toward the inboard side by the reaction force of the sub-lip 43 and the pressing load of the door glass 4 toward the inboard side are generated according to the 1st support state by the abutment of the sub-lip 43 with the general face 42 of the inboard side sealing lip 41, and the 2nd support state by the abutment of the sub-lip 43 with the general face 42 and the sealing lip convex portion 47 of the inboard side sealing lip 41, and thus even in the state where the door glass 4 is positioned slightly lower than the fully closed position, i.e., in the state where the door glass 4 displaces toward the inboard side, in the case where the door glass 4 vibrates due to bad road travel or the like, the inboard side sealing lip 41 can be prevented from separating from the door glass 4 to prevent the generation of abnormal noise.

[0104] Further, on the outboard side face between the root portion 41b of the inboard side sealing lip 41 of the inboard side side wall 40 and the bottom wall 20, a side wall convex portion 46 of approximately trapezoidal shape having a short side on the outboard side and protruding toward the outboard side is formed, and the sub-lip 43 is formed so as to protrude obliquely toward the inboard side face direction of the inboard side sealing lip 41 from the side wall convex portion 46, and thus the length of the sub-lip 43 is shortened compared to the present, and even in the case where the sub-lip 43 deteriorates over time, the reaction force (pressing force) toward the back face side of the inboard side sealing lip 41 can be suppressed from decreasing, and the inboard side sealing lip 41 can be prevented from separating from the door glass 4 to prevent the generation of abnormal noise.

[0105] Next, based on Figure 11 A 5th embodiment will be described. The 5th embodiment differs from the above-described 2nd embodiment in that the sub-lip 43 is not present. In order to prevent sound such as wind noise generated outside the passenger compartment from penetrating through the vehicle body and reaching the passenger compartment to improve sound insulation, sometimes a countermeasure of increasing the plate thickness of the door glass 4 is implemented. The 5th embodiment is suitable in the case where the thickness of the door glass 4 is thick.

[0106] Figure 11The state of abutment of the seal lip protrusion 47 of the inner side seal lip 41 and the side wall protrusion 46 when the door glass 4 is slightly lowered and displaced toward the inside of the vehicle. According to Figure 11 It is clear that if the door glass 4 is slightly lowered and displaced toward the inside of the vehicle, the seal lip protrusion 47 of the inner side seal lip 41 is pressed strongly by the side wall protrusion 46 and deformed.

[0107] As a result, at the inner side seal lip 41, a reaction force is generated via the seal lip protrusion 47, which presses the inside of the door glass 4 toward the outside of the vehicle via the inner side seal lip 41, and thus it is possible to prevent the inner side seal lip from separating from the door glass and generating a noise.

[0108] Further, in the state where the door glass 4 is displaced toward the inside of the vehicle Figure 11 The side wall protrusion 46 has a shape of a trapezoid in which the short side is on the outside of the vehicle and protrudes toward the outside of the vehicle, but is not limited to a trapezoid, and can be, for example, a rectangle, an arc such as a semicircle, or the like.

[0109] Further, the seal lip protrusion 47 can not have the protrusion surface protrusion 47b, and can have, for example, the shape of the third embodiment or the fourth embodiment. That is, it is sufficient that the seal lip protrusion 47 of the inner side seal lip 41 is pressed strongly by the side wall protrusion 46 and deformed.

[0110] Further, in the case where the door glass 4 is displaced toward the inside of the vehicle Figure 11 Further, in the case where the door glass 4 is displaced toward the inside of the vehicle

[0111] In the embodiments of the application, as a material constituting the glass run 10, rubber, thermoplastic elastomer, soft synthetic resin, or the like can be used. In the case of rubber, as a thermoplastic elastomer, an olefin-based thermoplastic elastomer (TPO) or a dynamically cross-linked thermoplastic elastomer (TPV) is preferable in terms of weather resistance, cycle, cost, and the like, for EPDM (ethylene-propylene rubber).

[0112] The application is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the application.

[0113] For example, in the first embodiment, the shape of the second to fourth embodiments can be used for the seal lip protrusion 47.

[0114] For example, regarding the position where the seal lip protrusion 47 is formed, in the above-described first, second, and fifth embodiments, the seal lip protrusion 47 is formed on the root 41b side of the inner side seal lip 41 slightly closer to the inner side seal lip 41 than the seal lip front end portion 41a of the inner side seal lip 41, and in the third and fourth embodiments, the seal lip protrusion 47 is formed on the seal lip front end portion 41a of the inner side seal lip 41, but in the first, second, and fifth embodiments, the seal lip protrusion 47 can be formed on the seal lip front end portion 41a of the inner side seal lip 41, and in the third and fourth embodiments, the seal lip protrusion 47 can be formed on the root 41b side of the inner side seal lip 41 slightly closer to the inner side seal lip 41 than the seal lip front end portion 41a of the inner side seal lip 41.

[0115] For example, the above-described embodiments have been described with respect to the rear side longitudinal edge portion, but the configuration of the inner side portion can also be applied to the mold forming portion related to the front side longitudinal edge portion.

[0116] For example, in the above-described embodiments, in the process of extending the cross section of the extrusion formed portion, it is assumed that the seal lip protrusion 47 and the side wall protrusion 46 are formed in the mold forming portion, but with respect to the shape of the inner side of the glass run, the above-described embodiments can be formed in the mold forming portion regardless of the cross section of the extrusion formed portion.
