Description

Technical Field

[0001] The present invention relates to a glass run attached to a door of a vehicle such as an automobile.

Background Art

[0002] Improving the quietness of vehicles such as automobiles enhances the comfort of passengers, so it has a high appeal for improving product power. Also, in electric vehicles that are becoming more popular, since the conventionally installed engine is eliminated, the main remaining noises due to the elimination of the engine noise are the road noise and the wind noise becoming prominent. Therefore, the need for technologies to reduce them is increasing.

[0003] For example, there is known a technique for reducing vibration by using impedance matching that brings the impedance of a glass run closer to the impedance of glass by increasing the rigidity of the glass run (for example, Patent Document 1).

[0004] FIG. 11 shows the technique disclosed in Patent Document 1. A glass run 100 having a bottom wall 200, an outer vehicle side wall 300, and an inner vehicle side wall 400 as basic skeletons, and the basic skeletons are attached to a door frame groove portion 500 formed in a door frame 310 to guide the raising and lowering of a door glass 600. On the inner vehicle side of the outer vehicle side wall 300, there is formed a thick portion 330 that protrudes inward of the vehicle and slidably contacts the door glass 600 and has a higher hardness than the outer vehicle side wall main body portion 320 of the outer vehicle side wall 300.

[0005] Then, by the contact between the thick portion 330 having a high hardness and the door glass 600, it is possible to reduce vibration by efficiently propagating the vibration of the door glass 600 to the glass run 100 by using impedance matching.

[0006] Furthermore, by forming a structure in which the outer side wall 300, which has a high-hardness, thick portion 330, abuts against the door frame groove portion 500, and sandwiching the door glass 600 between the door glass 600 and the door frame groove portion 500, the rigidity of the outer side wall 300, including the thick portion 330, with respect to the door glass 600 and the door frame groove portion 500 can be increased, and vibration can be reduced by utilizing impedance matching. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2023-53894 [Overview of the project] [Problems that the invention aims to solve]

[0008] Incidentally, in automobiles and other vehicles, the door frame 310 (the door frame groove 500 formed inside the door frame 310) is curved in the vertical and longitudinal directions of the vehicle. Also, the door glass 600 is curved in the vertical and longitudinal directions of the vehicle. Furthermore, the degree of curvature of the door frame 310 (door frame groove 500) and the degree of curvature of the door glass 600 are different.

[0009] The glass run, which is formed into an almost straight shape, conforms to the door frame due to the softness of its material. However, in the glass run 100, where a hard, thick section 330 is formed, variations in the curvature of the door glass 600 and the door frame 310 (door frame groove section 500) cause a gap to form between the thick section 330 and the door glass 600, particularly in the region from just before the door glass 600 is closed to the position where it is completely closed, near the upper corner of the door glass 600.

[0010] In the region where this gap occurs, vibrations from the door glass 600 cannot be transmitted to the thicker portion 330 (outer side wall 300) which has higher hardness. Therefore, the effect of vibration reduction using impedance matching is reduced compared to when the thicker portion 330 is in contact with the door glass 600 over its entire surface. [Means for solving the problem]

[0011] The present invention provides a glass run that fully utilizes impedance matching to reduce vibrations even when a gap occurs between the exterior side wall of the vehicle and the door glass due to variations in the curvature of the door glass and door frame.

[0012] To solve the above problems, the first aspect of the present invention is a glass run comprising a bottom wall, an outer side wall, and an inner side wall, wherein the outer side wall has an outer hard portion that is harder than the outer side wall, the inner side wall has an inner seal lip that extends outward and toward the bottom wall and slides against the door glass, the inner side wall has an inner hard portion that is harder than the inner side wall, and between the outer side of the inner side wall and the seal lip, a seal lip side hard portion that is harder than the inner seal lip is formed on the inner side of the inner seal lip or on the outer side of the inner side wall, wherein when the seal lip side hard portion is formed on the inner seal lip, the seal lip side hard portion abuts against the inner side wall at least when the door glass is closed, and when the seal lip side hard portion is formed on the inner side wall, the seal lip side hard portion abuts against the inner seal lip at least when the door glass is closed.

[0013] In the first aspect of the present invention, an interior seal lip is formed on the interior side wall of the vehicle, extending outward and toward the bottom wall, and sliding against the door glass. An interior hard portion is formed on the interior side wall, which is harder than the interior side wall. Between the exterior side of the interior side wall and the seal lip, a seal lip side hard portion is formed, which is harder than the interior seal lip, on the interior side of the interior seal lip or on the exterior side of the interior side wall. When the seal lip side hard portion is formed on the interior seal lip, the seal lip side hard portion contacts the interior side wall at least when the door glass is closed. When the seal lip side rigid portion is formed on the inner side wall, the seal lip side rigid portion contacts the inner seal lip at least when the door glass is closed. Therefore, even in areas where gaps occur as pointed out in the above problem, such as areas where a gap occurs between the outer side wall and the door glass, the contact between the door glass, the inner seal lip, the seal lip side rigid portion, and the inner side wall (inner rigid portion) increases the rigidity from the inner seal lip to the inner side wall, allowing vibrations of the door glass to be transmitted to the glass run on the inside of the door glass. Furthermore, the vibrations can be transmitted to the door side to which the glass run is attached. As a result, the effect of vibration reduction using impedance matching can be fully demonstrated throughout the entire glass run.

[0014] Furthermore, the rigid portion formed within the inner side wall of the vehicle may be formed exposed on the outer side of the inner side wall, or it may be formed inside the inner side wall.

[0015] If the rigid portion on the interior side is formed exposed on the exterior side of the interior side wall, it is desirable for the rigid portion on the seal lip side and the rigid portion on the interior side to come into contact with each other, in order to increase the rigidity of the glass run side, which is composed of the interior seal lip, the rigid portion on the seal lip side, the rigid portion on the interior side, and the interior side wall.

[0016] Furthermore, if the interior rigid portion is formed inside the interior side wall, it is desirable for the seal lip side rigid portion to abut against the interior side wall in the region where the interior rigid portion is formed, from the viewpoint of increasing the rigidity of the glass run side, which is composed of the interior seal lip, the seal lip side rigid portion, and the interior side wall (interior rigid portion).

[0017] Furthermore, the rigid portion formed within the inner side wall may be formed by penetrating the inner side wall from the outer side to the inner side, or, for example, by being exposed on both the outer and inner sides of the inner side wall and formed separately.

[0018] A second aspect of the present invention is a glass run in which, in the first aspect, the hardness of the hard portion on the seal lip side is the same as the hardness of the hard portion on the interior side, or is between the hardness of the seal lip on the interior side and the hard portion on the interior side.

[0019] In the second aspect of the present invention, the hardness of the seal lip side hard portion is the same as, or between, the hardness of the interior side hard portion and the interior side hard portion. Therefore, the contact between the door glass, the interior seal lip, the seal lip side hard portion, the interior side wall (interior side hard portion), and the door increases the rigidity from the interior seal lip to the interior side wall (interior side hard portion) in the glass run, allowing vibrations from the door glass to be transmitted to the glass run. As a result, the vibration reduction effect using impedance matching can be fully demonstrated.

[0020] A third aspect of the present invention is that, in the first and second aspects, the seal lip side hard portion is a glass run formed in an area where the outer side of the door glass and the outer hard portion do not come into contact when the door glass is closed, or, when an outer seal lip is formed on the outer side wall that extends inward and towards the bottom wall and slides against the door glass, and the outer seal lip and the outer hard portion can come into contact, the outer seal lip and the outer hard portion do not come into contact.

[0021] Here, in the region where the outer side of the door glass does not contact the outer side hard portion, and in the region where the outer side seal lip does not contact the outer side hard portion, when the outer side hard portion is formed inside the outer side wall, the outer side wall of the region where the outer side hard portion is formed is included.

[0022] In the third aspect of the present invention, when the door glass is closed, the hard portion on the seal lip side extends inside the vehicle and toward the bottom wall side on the outer side of the door glass in a region where the outer side of the door glass does not contact the outer side hard portion or on the outer side wall, and an outer side seal lip that slidably contacts the door glass is formed. When the outer side seal lip and the outer side hard portion can contact each other, it is formed in a region where the outer side seal lip and the outer side hard portion do not contact each other, that is, in the region where the gap pointed out in the above problem occurs. Therefore, compared with the case where the hard portion on the seal lip side is formed over the entire area, that is, including the region where no gap occurs, the glass run can be lightened.

[0023] In the fourth aspect of the present invention, in the third aspect, the hard portion on the seal lip side is a glass run formed by attaching to the inner side seal lip or the inner side wall of the vehicle.

[0024] In the fourth aspect of the present invention, since the hard portion on the seal lip side is formed by attaching to the inner side seal lip or the inner side wall of the vehicle, it will be retrofitted to the glass run after extrusion molding of the cross-section where the hard portion on the seal lip side is not formed. As a result, the molding of the glass run becomes easier compared to the extrusion molding in which the hard portion on the seal lip side is formed in the region where the outer side of the door glass and the outer side wall do not contact each other. Therefore, this aspect is useful for the extrusion molding of the glass run.

[0025] In addition, forming the hard portion on the seal lip side by attaching it to the inner side seal lip or the inner side wall of the vehicle can easily cope with the differences in the curvature of the door frame and the door glass among different vehicle models. Therefore, the glass run with a cross-section where the hard portion on the seal lip side is not formed can be deployed to other vehicle models.

[0026] A fifth aspect of the present invention is a glass run including a bottom wall, an outer vehicle-side wall, and an inner vehicle-side wall. An outer vehicle-side hard portion having a higher hardness than the outer vehicle-side wall is formed on the outer vehicle-side wall, and an inner vehicle-side hard portion having a higher hardness than the inner vehicle-side wall is formed on the inner vehicle-side wall. An inner vehicle-side seal lip that extends outwardly of the vehicle and toward the bottom wall and whose tip portion curves toward the inner vehicle-side wall side is formed on the inner vehicle-side wall. The inner vehicle-side seal lip includes a side wall side portion connected to the inner vehicle-side wall and a seal lip hard portion having a higher hardness than the side wall side portion connected to the side wall side portion. The seal lip hard portion abuts against the door glass and the inner vehicle-side wall at least when the door glass is closed.

[0027] In the fifth aspect of the present invention, an inner vehicle-side seal lip that extends outwardly of the vehicle and toward the bottom wall and whose tip portion curves toward the inner vehicle-side wall side is formed on the inner vehicle-side wall. The inner vehicle-side seal lip includes a side wall side portion connected to the inner vehicle-side wall and a seal lip hard portion having a higher hardness than the side wall side portion connected to the side wall side portion. Since the seal lip hard portion abuts against the door glass and the inner vehicle-side wall at least when the door glass is closed, vibration of the door glass can be propagated to the glass run by the contact of the door glass, the seal lip hard portion, and the inner vehicle-side wall (inner vehicle-side hard portion) even in a region where a gap occurs, such as a region where a gap occurs between the outer vehicle-side wall and the door glass. Also, it can be propagated to the door side where the glass run is attached. As a result, the effect of reducing vibration using impedance matching can be sufficiently exhibited throughout the glass run.

[0028] The inner vehicle-side hard portion formed inside the inner vehicle-side wall may be formed to be exposed on the outer side of the inner vehicle-side wall or may be formed inside the inner vehicle-side wall.

[0029] When the inner vehicle-side hard portion is formed to be exposed on the outer side of the inner vehicle-side wall, it is desirable that the seal lip hard portion and the inner vehicle-side hard portion abut against each other from the viewpoint of increasing the rigidity of the glass run side constituted by the seal lip hard portion, the inner vehicle-side hard portion, and the inner vehicle-side wall.

[0030] Furthermore, if the interior rigid portion is formed inside the interior side wall, it is desirable for the seal lip rigid portion to abut against the interior side wall in the region where the interior rigid portion is formed, from the viewpoint of increasing the rigidity of the glass run side, which is composed of the seal lip rigid portion and the interior side wall (interior rigid portion).

[0031] Furthermore, the rigid portion formed within the inner side wall may be formed by penetrating the inner side wall from the outer side to the inner side, or, for example, by being exposed on both the outer and inner sides of the inner side wall and formed separately.

[0032] A sixth aspect of the present invention is that, in the fifth aspect, the hardness of the hard portion of the seal lip is the same as the hardness of the hard portion on the inside of the vehicle, or is between the side wall portion of the seal lip on the inside of the vehicle and the hard portion on the inside of the vehicle.

[0033] In the sixth aspect of the present invention, the hardness of the hard portion of the seal lip is the same as the hardness of the hard portion on the interior side, or is between the hardness of the side wall portion of the seal lip on the interior side and the hard portion on the interior side. Therefore, vibrations of the door glass can be transmitted to the hard portion of the seal lip by impedance matching through contact between the door glass and the hard portion of the seal lip, and vibrations of the door glass can be transmitted to the interior side wall (hard portion on the interior side) through contact between the hard portion of the seal lip and the interior side wall (hard portion on the interior side). As a result, the effect of vibration reduction using impedance matching can be fully demonstrated throughout the entire glass run.

[0034] A seventh aspect of the present invention is that, in the fifth and sixth aspects, a thin folding base portion is formed on the side wall portion of the inner seal lip near the connection portion with the hard portion of the seal lip.

[0035] In the seventh aspect of the present invention, a thin folding point is formed near the connection point with the hard portion of the seal lip on the side wall of the interior seal lip. As a result, the hard portion of the seal lip abuts against the interior side wall (interior hard portion), and in the region where the door glass is located on the interior side, the side wall deforms at the folding point, thereby reducing the pressing force that the hard portion of the seal lip exerts on the door glass to the exterior. Consequently, adverse effects on the sliding of the door glass can be prevented.

[0036] The eighth aspect of the present invention is that, in the seventh aspect, the bending base portion is formed on the vehicle side of the side wall.

[0037] In the eighth aspect of the present invention, since the bending point is formed on the side of the side wall on the vehicle side, the side of the side wall is easily deformed at the bending point. As a result, the pressing force exerted by the hard seal lip portion on the door glass outwards can be reduced, thus preventing adverse effects on the sliding of the door glass. [Effects of the Invention]

[0038] A glass run comprising a bottom wall, an outer side wall, and an inner side wall, wherein the outer side wall has an outer hard portion with a higher hardness than the outer side wall, and the inner side wall has an inner seal lip that extends outward and toward the bottom wall and slides against the door glass, and the inner side wall has an inner hard portion with a higher hardness than the inner side wall, and between the outer side of the inner side wall and the seal lip, a seal lip side hard portion with a higher hardness than the inner seal lip is formed on the inner side of the inner seal lip or on the outer side of the inner side wall, and the seal lip side hard portion is formed on the inner seal lip. In this case, at least when the door glass is closed, it contacts the interior side wall, and if the hard part on the seal lip side is formed on the interior side wall, at least when the door glass is closed, it contacts the interior seal lip. Therefore, even in areas where gaps occur as pointed out in the above problem, such as areas where a gap occurs between the exterior side wall and the door glass, the contact between the door glass, the interior seal lip, the hard part on the seal lip side and the interior side wall (interior hard part) increases the rigidity from the interior seal lip to the interior side wall, allowing vibrations of the door glass to be transmitted to the glass run on the interior side of the door glass. Furthermore, it can be transmitted to the door side to which the glass run is attached. As a result, the effect of vibration reduction using impedance matching can be fully demonstrated throughout the entire glass run.

[0039] The glass run comprises a bottom wall and an outer side wall, wherein the outer side wall has an outer hard portion with higher hardness than the outer side wall, and the inner side wall has an inner hard portion with higher hardness than the inner side wall, and the inner side wall has an inner seal lip that extends outward and toward the bottom wall, with its tip curving toward the inner side wall, and the inner seal lip comprises a side wall portion connected to the inner side wall and a seal lip hard portion with higher hardness than the side wall portion connected to the side wall portion, and the seal lip hard portion contacts the door glass and the inner side wall at least when the door glass is closed, so that even in areas where gaps occur as pointed out in the above problem, such as areas where a gap occurs between the outer side wall and the door glass, vibrations of the door glass can be transmitted to the glass run by contact between the door glass, the seal lip hard portion and the inner side wall (inner hard portion). Furthermore, vibrations can be transmitted to the door side to which the glass run is attached. As a result, the vibration reduction effect using impedance matching can be fully realized throughout the entire glass run. [Brief explanation of the drawing]

[Figure 11] This is a cross-sectional view showing a conventional glass run mounting structure (Patent Document 1). [Modes for carrying out the invention]

[0041] A first embodiment of the present invention will be described with reference to Figures 1 to 3. Figure 1 shows a front view of the left front door 1 of an automobile as seen from the outside of the vehicle. A door frame 3 is attached to the upper part of the door body 2 that constitutes this front door 1. A window opening is formed by this door frame 3 and the upper edge of the door body 2. A glass run 10 is installed in the door frame groove 6 formed in the door frame 3 and inside the door body 2 to guide the raising and lowering movement of the door glass 4. The present invention is applicable not only to the left front door 1, but also to the right front door and the left and right rear doors. It is also applicable to sliding doors in which the door glass rises and falls.

[0042] Figure 2 is a simplified front view of the glass run 10 as seen from the outside of the vehicle. This glass run 10 is composed of a first extruded section 11 corresponding to the horizontal frame portion of the door frame 3, a second extruded section 12 corresponding to the front vertical frame portion of the front door 1, and a third extruded section 13 corresponding to the rear vertical frame portion. The front end of the first extruded section 11 is connected to the upper end of the second extruded section 12 by a first molded section 14. The rear end of the first extruded section 11 is connected to the upper end of the third extruded section 13 by a second molded section 15. Figures 1 and 2 are also used in the second to eighth embodiments described later.

[0043] Figure 3 is a cross-sectional view of section AA in Figure 1, showing the glass run 10 attached to the door frame groove 6 of the door frame 3 and the door glass 4 closed. This position is the third extruded section 13 near the second molded section 15, and is the region where a gap occurs between the door glass 4 and the exterior hard section 33, which will be described later. The glass run 10 includes a bottom wall 20, an exterior side wall 30, and an interior side wall 40. The interior side wall 40 is formed to be larger than the exterior side wall 30, and its shape is asymmetrical, with the interior side being larger.

[0044] An outer groove 21 is formed at the connection point between the bottom wall 20 and the outer side wall 30, and an inner groove 22 is formed at the connection point between the bottom wall 20 and the inner side wall 40. Here, the thickness of the inner groove 22 is formed to be greater than the thickness of the outer groove 21. In addition, in order to increase the thickness of the inner groove 22, a protrusion 25 is formed on the opposite side of the inner groove 22, extending from the bottom wall 20. Note that if the thickness of the inner groove 22 is ensured, the protrusion 25 does not need to be formed.

[0045] The bottom wall 20 is formed in a roughly plate-like shape, and multiple bottom wall recesses 23 are formed on the inner surface of the bottom wall 20 (the side facing the door glass 4) in a continuous, parallel manner along its longitudinal direction. In addition, a bottom wall seal lip 24 is formed on the outer surface of the bottom wall 20.

[0046] On the outer side of the outer side wall 30, an outer retaining lip 31 is formed near the connection point with the bottom wall 20, extending toward the tip of the outer side wall 30. In addition, a thinned portion 32 is formed at the base of the outer retaining lip 31 on the outer side wall 30.

[0047] On the interior side of the exterior side wall 30, an exterior hard portion 33 is formed, which has a higher hardness than the material constituting the exterior side wall 30. Furthermore, the exterior hard portion 33 is divided into an interior hard portion 33a formed on the interior side of the exterior side wall 30 and an exterior hard portion 33b formed on the exterior side. The interior hard portion 33a is formed to protrude inward from the exterior side wall 30. On the other hand, the exterior hard portion 33b is formed inside the exterior side wall 30 and is formed to be exposed on the exterior side of the exterior side wall 30. Furthermore, the exterior hard portion 33b is formed at a position opposite to the interior hard portion 33a. Multiple convex ribs 33c are formed continuously and parallel to each other in the longitudinal direction on the inner surface of the rigid inner portion 33a.

[0048] Furthermore, the outer rigid portion 33 does not have to be formed by dividing it into an inner rigid portion 33a and an outer rigid portion 33b; it may consist only of the inner rigid portion 33a, or it may be formed penetrating from the inner side to the outer side of the vehicle.

[0049] The hard outer portion 33b is not formed in the thin-walled portion 32. The hard outer portion 33b is formed in the direction of the tip 34 of the outer side wall 30 from the thin-walled portion 32.

[0050] In the outer side wall 30 of the vehicle, a stepped portion 35 is formed in which the thickness increases from the hard outer portion 33b toward the tip portion 34.

[0051] An exterior seal lip 36 is formed on the exterior side wall 30, extending inward from the tip 34 towards the bottom wall 20. In this embodiment, the exterior seal lip 36 does not contact the hard interior portion 33a. A retaining rib 37 is formed on the exterior side of the tip 34 of the exterior side wall 30. An exterior cover lip 38 is formed on the exterior side of the exterior side wall 30, extending inward from the base of the exterior seal lip 36 towards the tip, away from the bottom wall 20.

[0052] On the exterior side of the interior side wall 40, a first interior seal lip 41 is formed, extending from the tip of the interior side wall 40 outwards towards the bottom wall 20. A second interior seal lip 42 is formed between the first interior seal lip 41 and the bottom wall 20, and extending towards the bottom wall 20. Furthermore, on the exterior side of the interior side wall 40, on the side of the second interior seal lip 42 towards the bottom wall 20, a sub-lip 43 is formed, extending outwards and in the opposite direction to the bottom wall 20. The sub-lip 43 may also be formed to extend towards the bottom wall 20. Moreover, the sub-lip 43 may be omitted.

[0053] Furthermore, a second interior retaining lip 45 is formed on the interior side of the interior side wall 40, near the connection point with the bottom wall 20, and extending toward the tip of the interior side wall 40. A first interior retaining lip 44 is formed between the second interior retaining lip 45 and the tip of the interior side wall 40, extending toward the tip of the interior side wall 40. In addition, a contact rib 46 is formed between the first interior retaining lip 44 and the second interior retaining lip 45.

[0054] An interior cover lip 47 is formed on the interior side of the vehicle, and on the bottom wall 20 side, from the tip of the interior side wall 40.

[0055] In the interior side wall 40, an interior hard portion 48, which has a higher hardness than the material constituting the interior side wall 40, is formed penetrating from the outside to the inside of the vehicle, in the region from the bottom wall 20 side of the base portion of the first interior seal lip 41 to the first interior seal lip 41 side of the base portion of the second interior seal lip 42.

[0056] Furthermore, the interior rigid portion 48 may not penetrate from the exterior to the interior, but may be formed by dividing it into exterior and interior sections, similar to the exterior rigid portion 33 described above. Alternatively, it may be formed inside the interior side wall 40.

[0057] On the outer side of the inner hard portion 48, a seal lip side hard portion 49 is formed, which has a higher hardness than the material constituting the first inner seal lip 41. In this embodiment, the hardness of the seal lip side hard portion 49 is the same as that of the inner hard portion 48. Also, the hardness of the inner hard portion 48 is the same as that of the outer hard portion 33. Note that the hardness of the seal lip side hard portion 49, the inner hard portion 48, and the outer hard portion 33 do not have to be the same.

[0058] Furthermore, the hard portion 49 on the seal lip side was formed by adhesively attaching it to the outer surface of the hard portion 48 on the inner side of the vehicle. Alternatively, it may be attached by other methods such as welding.

[0059] The seal lip side hard portion 49 is formed in the region where a gap is generated between the door glass 4 and the outer hard portion 33 in the longitudinal direction of the third extruded portion 13 when the door glass 4 is closed. In this case, it is desirable from the viewpoint of the sliding properties of the door glass 4 to form the seal lip side hard portion 49 to match the shape of the gap between the door glass 4 and the outer hard portion 33, but the seal lip side hard portion 49 may also be formed to a constant thickness.

[0060] Furthermore, it is desirable to also form a seal lip side hard portion 49 in the second molded portion 15. In this case, the seal lip side hard portion 49 is molded during the molding process to match the shape of the gap between the door glass 4 and the vehicle exterior hard portion 33, or to a certain thickness.

[0061] In this embodiment, the outer rigid portion 33, the inner rigid portion 48, and the seal lip side rigid portion 49 are made of PP (polypropylene), while the glass run 10, excluding the outer rigid portion 33, the inner rigid portion 48, and the seal lip side rigid portion 49, is made of olefin-based thermoplastic elastomer (TPO) with an IRHD (International Rubber Hardness) of 80±5 and manufactured by extrusion molding. The outer rigid portion 33, the inner rigid portion 48, and the seal lip side rigid portion 49 may also be made of the same TPO as the other parts; in this case, an IRHD of 100±5 is desirable. Furthermore, other rigid resin materials besides PP, such as olefin-based resins like polystyrene, may also be used.

[0062] In Figure 3, the center pillar 7 is attached to the outer side of the door frame groove 6. The door frame groove 6 is made of metal.

[0063] When the glass run 10 is attached to the door frame groove 6 of the door frame 3, the bottom wall seal lip 24 elastically contacts the door frame groove 6 on the bottom wall 20, and the protruding portion 25 abuts against the door frame groove 6.

[0064] On the exterior side wall 30, the exterior retaining lip 31 abuts against the hemmed tip 61 of the hemmed door frame groove 6, and the hard exterior portion 33b abuts against the interior side of the hemmed door frame groove 6 over a surface area.

[0065] Furthermore, the stepped portion 35 does not contact the bent portion of the hemming process, that is, the outer end portion 62 of the door frame groove 6, and a gap portion 39 is formed between the stepped portion 35 and the outer end portion 62 of the door frame groove 6. Also, the tip portion of the center pillar 7 is in contact with the retaining rib 37.

[0066] On its exterior side, the interior side wall 40 abuts against the door frame groove 6 with the abutment rib 46, and the first interior retaining lip 44 and the second interior retaining lip 45 abut against the first curved portion 63 and the second curved portion 64 of the door frame groove 6. The interior cover lip 47 abuts against the door frame 3. The interior side of the interior hard portion 48 abuts against the door frame groove 6 over its surface.

[0067] In Figure 3, the outer groove portion 21 is deformed so that the inner side of the outer side wall 30 is very close to the bottom wall 20, and the inner groove portion 22 is deformed so that the outer side of the inner side wall 40 and the bottom wall 20 are not as close as the outer side, and is attached to the door frame groove portion 6.

[0068] When the door glass 4 is inserted between the outer side wall 30 and the inner side wall 40, on the outer side, the outer cover lip 38 deforms toward the opposite side from the bottom wall 20, and the outer seal lip 36 deforms toward the bottom wall 20 and the outer side wall 30, elastically contacting the outer side of the door glass 4. Also, the outer side of the door glass 4 abuts against the rib 33c formed on the inner side portion 33a of the outer hard portion 33.

[0069] On the other hand, on the interior side, both the first interior seal lip 41 and the second interior seal lip 42 deform toward the bottom wall 20 and the interior side wall 40, and elastically contact the interior side of the door glass 4.

[0070] As the door glass 4 rises, and in the region from just before it closes to when it is completely closed, variations in the curvature of the door frame groove 6 (door frame 3) and the door glass 4 may cause a gap to form between the rib 33c of the outer rigid part 33 and the door glass 4, as shown in Figure 3.

[0071] In the region where a gap occurs between the exterior hardened portion 33 and the door glass 4, the door glass 4 is positioned further inward compared to the region where the exterior hardened portion 33 and the door glass 4 are in contact. As a result, both the first interior seal lip 41 and the second interior seal lip 42 move towards the interior side wall 40, increasing the degree of deformation. At this time, the seal lip side hardened portion 49 formed on the interior hardened portion 48 comes into contact with the first interior seal lip 41, and the first interior seal lip 41, the seal lip side hardened portion 49, and the interior hardened portion 48 are pressed together so as to be sandwiched between the door glass 4 and the door frame groove 6.

[0072] Next, a second embodiment of the present invention will be described with reference to Figure 4. Figure 4 is a cross-sectional view AA of Figure 1, showing the glass run 10 attached to the door frame groove 6 of the door frame 3 and the door glass closed. This position is the third extrusion molding section 13 near the second molded section 15, and is the region where a gap occurs between the door glass 4 and the outer hardened section 33.

[0073] The differences between this second embodiment and the first embodiment described above are, firstly, that in the interior side wall 40, the interior rigid portion 48 is formed to penetrate from the outside to the inside of the vehicle and protrude inward from the bottom wall 20 side of the base portion of the second interior seal lip 42 to the interior side wall 40 side of the interior groove portion 22; and secondly, that the sub-lip 43 is not formed. Furthermore, the reason why the rigid portion 48 on the interior side protrudes inward is based on the fact that the contact rib 46 is formed in the first embodiment described above.

[0074] In the region where a gap occurs between the exterior hardened portion 33 and the door glass 4, the door glass 4 is positioned further inward compared to the region where the exterior hardened portion 33 and the door glass 4 are in contact. As a result, both the first interior seal lip 41 and the second interior seal lip 42 move towards the interior side wall, increasing the degree of deformation. At this time, the seal lip side hardened portion 49 formed on the interior hardened portion 48 comes into contact with the second interior seal lip 42, and the second interior seal lip 42, the seal lip side hardened portion 49, and the interior hardened portion 48 are pressed together so as to be sandwiched between the door glass 4 and the door frame groove 6.

[0075] Next, a third embodiment of the present invention will be described with reference to Figure 5. Figure 5 is a cross-sectional view of BB in Figure 1, showing the glass run 10 attached to the door frame groove 6 of the door frame 3 and the door glass closed. This position is the second extrusion molding section 12 near the first molded section 14, and is the region where a gap occurs between the door glass 4 and the outer hardened section 33.

[0076] The differences between this third embodiment and the first embodiment described above are, firstly, in the basic frame, there is no difference in size between the inner side wall 40 and the outer side wall 30, and their shapes are asymmetrical, with the inner side being slightly larger; secondly, the outer side wall 30 has an outer cover lip 38 that extends from its tip 34 outwards and in the opposite direction to the bottom wall 20; and thirdly, in the inner side wall 40, the inner hard portion 48 is formed penetrating from the outside to the inside in the region between the base of the second inner seal lip 42 and the base of the sub-lip 43. The seal lip side hard portion 49 is formed on top of the inner hard portion 48, which is the same.

[0077] When the door glass 4 is inserted between the outer side wall 30 and the inner side wall 40 of the vehicle, in the region where a gap is created between the outer hard part 33 and the door glass 4, the door glass 4 is positioned more inward compared to the region where the outer hard part 33 and the door glass 4 are in contact. As a result, both the first inner seal lip 41 and the second inner seal lip 42 move toward the inner side wall, and the degree of deformation increases. At this time, the seal lip side hard part 49 formed on the inner hard part 48 comes into contact with the second inner seal lip 42, and the second inner seal lip 42, the seal lip side hard part 49, and the inner hard part 48 are pressed together so as to be sandwiched between the door glass 4 and the door frame groove 6.

[0078] Next, a fourth embodiment of the present invention will be described with reference to Figure 6. Figure 6 is a cross-sectional view of BB in Figure 1, showing the glass run 10 attached to the door frame groove 6 of the door frame 3 and the door glass 4 closed. This position is the second extrusion molding section 12 near the first molded section 14, and is the region where a gap occurs between the door glass 4 and the outer hardened section 33.

[0079] The main differences between this fourth embodiment and the third embodiment described above are, firstly, the shape of the door frame groove 6 on the interior side is different, with a larger area extending inward; secondly, corresponding to the difference in the door frame groove 6, the interior side of the hard part 48 is formed to protrude from the interior side wall 40; and thirdly, the sub-lip 43 is absent.

[0080] When the door glass 4 is inserted between the outer side wall 30 and the inner side wall 40 of the vehicle, in the region where a gap is created between the outer hard part 33 and the door glass 4, the door glass 4 is positioned more inward compared to the region where the outer hard part 33 and the door glass 4 are in contact. As a result, both the first inner seal lip 41 and the second inner seal lip 42 move toward the inner side wall, and the degree of deformation increases. At this time, the seal lip side hard part 49 formed on the inner hard part 48 comes into contact with the second inner seal lip 42, and the second inner seal lip 42, the seal lip side hard part 49, and the inner hard part 48 are pressed together so as to be sandwiched between the door glass 4 and the door frame groove 6.

[0081] Next, a fifth embodiment of the present invention will be described with reference to Figure 7. Figure 7 is a cross-sectional view of the door glass 4 when the glass run 10 is attached to a mold whose inner surface shape is the same as the door frame groove 6 of the door frame 3, which corresponds to the CC cross-sectional view of Figure 1. This position is the first extrusion molding section 11 near the first mold molding section 14, and is a region where a gap occurs between the exterior seal lip 36 and the exterior hard section 33.

[0082] The main differences between this fifth embodiment and the first embodiment described above are: firstly, in the basic frame, there is no difference in size between the inner side wall 40 and the outer side wall 30, and their shapes are asymmetrical, with the inner side being slightly larger; secondly, a glass-side seal lip 26 is formed on the door glass 4 side of the bottom wall 20; thirdly, on the outer side wall 30, the outer seal lip 36 extending from its tip 34 toward the inner side and toward the bottom wall 20 is capable of contacting the outer hard part 33; fourthly, the outer hard part 33 is formed only on the inner side of the outer side wall 30; and fifthly, a second inner seal lip 42 is not formed on the inner side wall 40.

[0083] It should be noted that the interior rigid portion 48 is formed to penetrate from the outside to the inside of the vehicle, extending from the bottom wall 20 side of the base portion of the second interior seal lip 42 to the interior side wall 40 side of the interior groove portion 22. Also, the exterior rigid portion 33 may be formed by dividing it into an interior rigid portion 33a and an exterior rigid portion 33b, as in the first embodiment, or it may be formed to penetrate from the inside to the outside of the vehicle.

[0084] When the door glass 4 is inserted between the outer side wall 30 and the inner side wall 40 of the vehicle, the outer sealing lip 36 that contacts the door glass 4 deforms toward the outer side wall 30 and comes into contact with the outer hard part 33. Therefore, the outer sealing lip 36, the outer hard part 33, and the outer side wall 30 are pressed together between the door glass 4 and the door frame groove 6 (door frame 3).

[0085] On the other hand, near the upper corner of the door glass 4 shown in Figure 7, in the region from just before the door glass 4 is closed to the position where it is completely closed, the door glass 4 is located on the inside of the vehicle compared to the region where the outer hard part 33 and the outer seal lip 36 are in contact. As a result, the outer seal lip 36 and the outer hard part 33 are not in contact. Meanwhile, the first inner seal lip 41 moves in the direction of the inner side wall 40, and the degree of deformation increases. At this time, the seal lip side hard part 49 formed on the inner hard part 48 comes into contact with the first inner seal lip 41, and the first inner seal lip 41, the seal lip side hard part 49, and the inner hard part 48 are pressed together so as to be sandwiched between the door glass 4 and the door frame groove 6.

[0086] Next, a sixth embodiment of the present invention will be described with reference to Figure 8. Figure 8 is a cross-sectional view AA of Figure 1, showing the glass run 10 attached to the door frame groove 6 of the door frame 3 and the door glass 4 closed.

[0087] The differences between this sixth embodiment and the second embodiment described above are, firstly, that the seal lip side hard portion 49 is not formed; secondly, that the second interior seal lip 42 extends outward and toward the bottom wall 20, and its tip portion is curved toward the interior side wall 40; thirdly, that the second interior seal lip 42 is composed of a side wall portion 50 connected to the interior side wall 40, and a seal lip hard portion 51 connected to the side wall portion 50 and having a higher hardness than the side wall portion 50; and fourthly, that a folding base portion 52 is formed on the interior side of the side wall portion 50 near the connection portion with the seal lip hard portion 51, and is thinner than the side wall portion 50. The seal lip hard portion 51 can come into contact with the door glass 4.

[0088] In this sixth embodiment, the second interior seal lip 42, which consists of a side wall portion 50 and a seal lip hard portion 51, is formed over the entire length of the third extruded portion 13.

[0089] As the door glass 4 rises, and in the region from just before it closes to when it is completely closed, variations in the curvature of the door frame groove 6 (door frame 3) and the door glass 4 may cause a gap to form between the outer hard part 33 and the door glass 4, as shown in Figure 8.

[0090] In the region where a gap occurs between the exterior rigid part 33 and the door glass 4, the door glass 4 is positioned further inward compared to the region where the exterior rigid part 33 and the door glass 4 are in contact. As a result, both the first interior seal lip 41 and the second interior seal lip 42 move in the direction of the interior side wall, and the degree of deformation increases. At this time, the seal lip rigid part 51 formed on the second interior seal lip 42 comes into contact with the door glass 4 and the interior rigid part 48. In addition, the side wall portion 50 flexes more inward based on the bending base point 52.

[0091] Furthermore, the seal lip hard portion 51 may come into contact with the interior hard portion 48 even in areas other than those where a gap occurs between the exterior hard portion 33 and the door glass 4.

[0092] Next, a seventh embodiment of the present invention will be described with reference to Figure 9. Figure 9 is a cross-sectional view of BB in Figure 1, showing the glass run 10 attached to the door frame groove 6 of the door frame 3 and the door glass 4 closed. This position is the second extrusion molding section 12 near the first molded section 14, and is the region where a gap occurs between the door glass 4 and the outer hardened section 33.

[0093] The differences between this seventh embodiment and the fourth embodiment described above are, firstly, that the seal lip side hard portion 49 is not formed; secondly, that the second interior seal lip 42 extends outward and toward the bottom wall 20, and its tip portion is curved toward the interior side wall 40; thirdly, that the second interior seal lip 42 is composed of a side wall portion 50 connected to the interior side wall 40, and a seal lip hard portion 51 connected to the side wall portion 50 and having a higher hardness than the side wall portion 50; and fourthly, that a folding base portion 52 is formed on the interior side of the side wall portion 50 near the connection portion with the seal lip hard portion 51, and is thinner than the side wall portion 50. The seal lip hard portion 51 can come into contact with the door glass 4.

[0094] In the region where a gap occurs between the exterior rigid part 33 and the door glass 4, the door glass 4 is positioned further inward compared to the region where the exterior rigid part 33 and the door glass 4 are in contact. As a result, both the first interior seal lip 41 and the second interior seal lip 42 move in the direction of the interior side wall, and the degree of deformation increases. At this time, the seal lip rigid part 51 formed on the second interior seal lip 42 comes into contact with the door glass 4 and the interior rigid part 48. In addition, the side wall portion 50 flexes more inward based on the bending base point 52.

[0095] Next, an eighth embodiment of the present invention will be described with reference to Figure 10. Figure 10 is a cross-sectional view corresponding to the CC cross-sectional view in Figure 1, in which the glass run 10 is attached to a mold whose inner surface shape is the same as the door frame groove 6 of the door frame 3, and the door glass 4 is closed. This position is the first extrusion molding section 11 near the first mold molding section 14, and is the region where a gap occurs between the exterior seal lip 36 and the exterior hard section 33.

[0096] The differences between this eighth embodiment and the fifth embodiment described above are, firstly, that the seal lip side hard portion 49 is not formed; secondly, that the first interior seal lip 41 extends outward and toward the bottom wall 20, and its tip portion is curved toward the interior side wall 40; thirdly, that the first interior seal lip 41 is composed of a side wall portion 50 connected to the interior side wall 40, and a seal lip hard portion 51 connected to the side wall portion 50 and having a higher hardness than the side wall portion 50; and fourthly, that a folding base portion 52 is formed on the interior side of the side wall portion 50 near the connection portion with the seal lip hard portion 51, and is thinner than the side wall portion 50. The seal lip hard portion 51 can come into contact with the door glass 4.

[0097] In the region where a gap occurs between the outer rigid portion 33 and the outer seal lip 36, the door glass 4 is positioned further inward compared to the region where the outer rigid portion 33 and the outer seal lip 36 are in contact. As a result, the first inner seal lip 41 moves in the direction of the inner side wall, and the degree of deformation increases. At this time, the seal lip rigid portion 51 formed on the first inner seal lip 41 comes into contact with the door glass 4 and the inner rigid portion 48. In addition, the side wall portion 50 flexes more inward based on the bending base portion 52.

[0098] As described in detail above, the embodiments of the present invention provide the following effects. (1) In the first to fourth embodiments described above, in the region where a gap occurs between the outer hard part 33 and the door glass 4, the door glass 4 is located on the inside of the vehicle compared to the region where the outer hard part 33 and the door glass 4 are in contact. As a result, both the first inner seal lip 41 and the second inner seal lip 42 move in the direction of the inner side wall, and the degree of deformation increases. At this time, the seal lip side hard part 49 formed on the inner hard part 48 comes into contact with the first inner seal lip 41 or the second inner seal lip 42, and the first inner seal lip 41 or the second inner seal lip 42, the seal lip side hard part 49 and the inner hard part 48 are pressed together so as to be sandwiched between the door glass 4 and the door frame groove 6. As a result, the rigidity between the first interior seal lip 41 or the second interior seal lip 42 and the interior rigid part 48 is increased, allowing vibrations of the door glass 4 to be transmitted to the glass run 10 on the interior side of the door glass 4. Furthermore, these vibrations can be transmitted to the door frame groove 6 to which the glass run 10 is attached. As a result, the vibration reduction effect using impedance matching can be fully realized throughout the entire glass run 10.

[0099] (2) In the fifth embodiment described above, in the region where a gap occurs between the exterior seal lip 36 and the exterior rigid part 33, the door glass 4 is located on the interior side of the vehicle compared to the region where the exterior rigid part 33 and the exterior seal lip 36 are in contact. As a result, the first interior seal lip 41 moves in the direction of the interior side wall 40, and the degree of deformation increases. At this time, the seal lip side rigid part 49 formed on the interior rigid part 48 comes into contact with the first interior seal lip 41, and the first interior seal lip 41, the seal lip side rigid part 49, and the interior rigid part 48 are pressed together so as to be sandwiched between the door glass 4 and the door frame groove 6. As a result, the rigidity of the first interior seal lip 41 and the interior rigid part 48 increases, and vibrations of the door glass 4 can be transmitted to the glass run 10 on the interior side of the door glass 4. They can also be transmitted to the door frame groove 6 to which the glass run 10 is attached. As a result, the vibration reduction effect using impedance matching can be fully realized throughout the entire glass run 10.

[0100] (3) In the sixth and seventh embodiments described above, in the region where a gap occurs between the outer rigid part 33 and the door glass 4, the door glass 4 is located on the interior side of the vehicle compared to the region where the outer rigid part 33 and the door glass 4 are in contact. As a result, both the first interior seal lip 41 and the second interior seal lip 42 move toward the interior side wall, and the degree of deformation increases. At this time, the seal lip rigid part 51 formed on the second interior seal lip 42 comes into contact with the door glass 4 and the interior rigid part 48. As a result, impedance matching between the door glass 4 and the seal lip rigid part 51 allows vibrations of the door glass 4 to be transmitted to the glass run 10 on the interior side of the door glass 4. It can also be transmitted to the door frame groove 6 to which the glass run 10 is attached. As a result, the effect of vibration reduction using impedance matching can be fully demonstrated throughout the entire glass run 10.

[0101] (4) Furthermore, since a thin folding base portion 52 is formed on the side of the side wall portion 50 on the interior side, the hard seal lip portion 51 comes into contact with the interior side wall 40 (interior hard portion 48), and in the region where the door glass 4 is located on the interior side, the side of the side wall portion 50 is more easily deformed at the folding base portion 52, and the pressing force that the hard seal lip portion 51 exerts on the door glass 4 to the exterior side can be reduced. As a result, adverse effects on the sliding of the door glass 4 can be prevented.

[0102] (5) In the eighth embodiment described above, in the region where a gap occurs between the exterior seal lip 36 and the exterior hard portion 33, the door glass 4 is located on the interior side of the vehicle compared to the region where the exterior seal lip 36 and the exterior hard portion 33 are in contact. As a result, the first interior seal lip 41 moves in the direction of the interior side wall, and the degree of deformation increases. At this time, the seal lip hard portion 51 formed on the first interior seal lip 41 comes into contact with the door glass 4 and the interior hard portion 48. Also, the side wall portion 50 deflects more inward based on the bending base portion 52. As a result, impedance matching between the door glass 4 and the seal lip hard portion 51 allows vibrations of the door glass 4 to be transmitted to the glass run 10 on the interior side of the door glass 4. It can also be transmitted to the door frame groove portion 6 to which the glass run 10 is attached. As a result, the effect of vibration reduction using impedance matching can be fully demonstrated throughout the entire glass run 10.

[0103] In carrying out the present invention, the invention is not limited to the embodiments described above, and various modifications are possible as long as they do not depart from the purpose of the invention.

[0104] Although the above embodiment describes a door frame 3 equipped with a door frame groove 6, the present invention can also be applied to a door frame 3 that does not have a door frame groove 6. In this case, for example, an exterior cover lip is formed on the exterior side wall 30, extending outwards and toward the bottom wall 20, an outer frame is inserted between the exterior cover lip and the exterior side wall 30 to bring the outer frame into contact with the exterior side wall 30 (or exterior hard part 33), and an inner frame is inserted between the interior side wall 40 and the interior cover lip 47 to bring the inner frame into contact with the interior side wall 40 (or interior hard part 48).

[0105] In the first to fifth embodiments described above, the seal lip side rigid portion 49 was formed on the vehicle side rigid portion 48, but it may also be formed by attaching or molding to the vehicle side surface of the first vehicle side seal lip 41 or the second vehicle side seal lip 42 facing the vehicle side rigid portion 48.
