Description

[Technical Field]

[0001] The present invention relates to a parting seal member for a vehicle. [Background technology]

[0002] BACKGROUND ART Conventionally, there is a vehicle border seal member that is attached to a pillar and has a border lip that seals the border gap between a window glass that is provided in a sashless door of a vehicle and can be raised and lowered and the pillar (see, for example, Patent Document 1).

[0003] The parting seal member described in Patent Document 1 includes a base portion, a parting lip, and a seal lip. The base portion extends in the direction in which the window glass and the pillar are aligned, and has a side wall portion that overlaps with the clearance gap in the inward / outward direction of the vehicle via the window glass, and an extending wall portion that extends outward from one end of the side wall portion on the pillar side in the alignment direction.

[0004] The parting lip extends from the outer edge of the extending wall portion toward the edge of the window glass. The seal lip extends outward from the side wall portion and has a tip portion that extends closer to the extending wall portion in the arrangement direction as it gets further outward.

[0005] With this parting lip, the leading end of the seal lip abuts against the inner surface of the window glass, thereby preventing outside noise from entering the vehicle interior through the parting gap. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Chinese Utility Model No. 217227269 Summary of the Invention [Problem to be solved by the invention]

[0007] Such parting seal members are required to suppress the intrusion of outside noise while suppressing an increase in size. [Means for solving the problem]

[0008] Various aspects of a vehicle parting seal member for solving the above problems will be described below. [Aspect 1] A vehicle border seal member having a border lip that seals a border gap between a pillar and a window glass that is provided in a sashless door of a vehicle and can be raised and lowered, and that is attached to the pillar, When the inside and outside of the vehicle in the inward and outward directions through the window glass are defined as the inside and the outside, respectively, The base and a first seal lip and a second seal lip, both of which are brought into contact with the inner surface of the window glass; the base portion has a side wall portion that extends in an arrangement direction of the window glass and the pillar and overlaps with the parting gap in the inward / outward direction, and an extending wall portion that extends outward from one end of the side wall portion on the pillar side in the arrangement direction, The parting lip extends from the outer end of the extension wall portion toward the edge of the window glass, the first seal lip has a first tip portion that extends outward from the side wall portion and that approaches the extending wall portion in the arrangement direction as it becomes more outward, the second seal lip has a second tip portion that extends outward from a portion of the side wall portion that is closer to the extending wall portion than the first seal lip, and that extends closer to the extending wall portion in the arrangement direction as it becomes more outward, A protrusion that protrudes toward the window glass in the thickness direction of the second seal lip is provided at the tip of the second tip portion. Vehicle parting seal material.

[0009] With this configuration, the first seal lip and the second seal lip each abut against the inner surface of the window glass, thereby preventing outside noise from entering the vehicle cabin through the gap, compared to conventional gap seal members that have only one seal lip.

[0010] However, by providing the first seal lip and the second seal lip, the size of the parting seal member in the arrangement direction may become large. One solution to this problem is to reduce the distance between the first and second seal lips in the arrangement direction. However, in this case, when the first seal lip abuts against the inner surface of the window glass and collapses, it may interfere with the second seal lip, preventing the first or second seal lip from abutting properly against the window glass. This creates a new problem: the sealing performance of the first and second seal lips may be impaired.

[0011] In this regard, with the above configuration, since a protrusion is provided at the tip of the second tip portion, when the protrusion abuts against the inner surface of the window glass, the second seal lip falls toward the base portion by an amount corresponding to the protrusion of the protrusion, thereby preventing the first seal lip from interfering with the second seal lip when it falls.

[0012] Therefore, it is possible to suppress the intrusion of outside noise while suppressing an increase in size. [Aspect 2] The first seal lip is provided with a first thin-walled portion on a side surface facing the second seal lip, the first seal lip being partially thinned in thickness, The second seal lip is provided with a second thin-walled portion on a side surface facing the extending wall portion, the second seal lip being partially thinned in thickness, The second thin portion is located more inward than the first thin portion in the inward-outward direction. The vehicle parting seal member according to aspect 1.

[0013] According to this configuration, the second thin-walled portion is located more inward than the first thin-walled portion in the inward-outward direction. This reduces the amount of inclination of the first tip portion starting from the first thin-walled portion, while increasing the amount of inclination of the second tip portion starting from the second thin-walled portion. This reduces the gap between the first and second seal lips in the arrangement direction, and further prevents the first seal lip from interfering with the second seal lip when it inclines.

[0014] [Aspect 3] the second seal lip has a second base end portion that is closer to the base end than the second thin-walled portion, The thickness of the second base end portion is increased toward the base end side. A parting seal member for a vehicle according to aspect 2.

[0015] The provision of the second thin-walled portion makes it easier for the second seal lip to bend from the second thin-walled portion as a starting point. However, if the rigidity of the second base end portion of the second seal lip is low, the second seal lip may be pressed by the window glass and collapse toward the first seal lip.

[0016] In this regard, according to the above configuration, the thickness of the second base end portion is made greater toward the base end, thereby increasing the rigidity of the second base end portion and making it possible to prevent the second seal lip from collapsing toward the first seal lip.

[0017] [Aspect 4] the first seal lip has a first base end portion that is closer to the base end than the first thin portion and a first tip end portion that is closer to the tip end than the first thin portion, The first base end portion extends from the side wall portion so as to be farther away from the extending wall portion in the arrangement direction as it extends outward. The vehicle parting seal member according to aspect 2 or 3.

[0018] With this configuration, the position of the first thin-walled portion can be spaced apart from the second seal lip in the arrangement direction. This makes it possible to further reduce the gap between the base end of the first seal lip and the base end of the second seal lip in the arrangement direction, while increasing the gap between the first tip end of the first seal lip and the second tip end of the second seal lip. Therefore, when the first seal lip collapses, it is possible to further prevent interference with the second seal lip.

[0019] [Aspect 5] a base end thin portion is provided on an inner surface of a base end portion of the parting lip, a tip-side thin portion is provided on the inner surface of the parting lip closer to the tip than the base-side thin portion, The thickness of the distal thin portion is thinner than the thickness of the proximal thin portion. The vehicle parting seal member according to aspect 1.

[0020] With this configuration, the parting lip is more likely to collapse starting from the thin distal end portion. Therefore, the amount of collapse of the parting lip is smaller than when the parting lip does not have a thin distal end portion, i.e., when the parting lip collapses starting only from the thin proximal end portion. This reduces the step formed between the decorative surface of the parting lip and the outer surface of the window glass, thereby improving the flushness of the decorative surface of the pillar, the decorative surface of the parting lip, and the outer surface of the window glass. This improves the vehicle's appearance.

[0021] [Aspect 6] The thickness of the parting lip at a portion between the base end thin portion and the tip end thin portion is greater than that of other portions. A parting seal member for a vehicle according to aspect 5.

[0022] According to this configuration, the portion of the parting lip between the base end thin portion and the tip end thin portion is less likely to deform. This makes it easier to achieve the effect described in Aspect 5, where the parting lip collapses starting from the tip end thin portion. This more reliably improves the flushness of the decorative surface of the pillar, the decorative surface of the parting lip, and the outer surface of the window glass. [Effects of the Invention]

[0023] According to the present invention, it is possible to suppress the intrusion of outside noise while suppressing an increase in size. [Brief explanation of the drawings]

[0025] Hereinafter, one embodiment of a parting seal member for a vehicle (hereinafter referred to as a parting seal member 10) will be described with reference to the drawings. As shown in Figures 1 and 2, the parting seal member 10 seals the parting gap V between a pillar 80 and a window glass 91 that is arranged to be able to rise and fall on a sashless door 90 of a vehicle, and extends along the extension direction of the pillar 80.

[0026] The sashless door 90 of this embodiment is a front door. The pillar 80 is a center pillar, a so-called B pillar, that separates the entrance / exit opening and closing by the front door from the entrance / exit opening and closing by the rear door.

[0027] 2, the parting seal member 10 includes a base portion 20, a parting lip 30, a first seal lip 40, and a second seal lip 50. The parting seal member 10 has the same cross-sectional shape throughout the extension direction of the parting seal member 10. The parting seal member 10 is made of a resin material or a rubber material.

[0028] The first seal lip 40 and the second seal lip 50 are both formed of a material softer than the base portion 20 and are configured to abut against the inner surface of the window glass 91. The pillar 80 has a pillar outer part 81 and a pillar garnish 82 that covers the outer surface of the pillar outer part 81.

[0029] Next, a detailed description will be given of each component of the parting seal member 10. Note that the shape of each component of the parting seal member 10 will be described with reference to the shape when not in contact with the window glass 91 (hereinafter referred to as the natural state).

[0030] Hereinafter, the arrangement direction of the window glass 91 and the pillar 80 will be simply referred to as the arrangement direction L. Furthermore, the inward and outward directions of the inward and outward direction W of the vehicle through the window glass 91 will be referred to as the inward and outward directions, respectively. In this embodiment, the arrangement direction L and the inward and outward direction W coincide with the front-rear direction and the vehicle width direction, respectively, of the vehicle.

[0031] <Base 20> As shown in FIG. 2, the base portion 20 has a side wall portion 21 and an extending wall portion 22. The side wall portion 21 extends in the arrangement direction L and overlaps with the parting gap V in the inner-outer direction W.

[0032] The extending wall portion 22 extends outward from one end of the side wall portion 21 on the pillar 80 side in the arrangement direction L. The inner surface of the side wall portion 21 is provided with a support protrusion 26 that protrudes toward the pillar outer member 81 and is supported by the pillar outer member 81 .

[0033] The extending wall portion 22 has a mounting portion 23 protruding therefrom, which is mounted in a recess of the pillar garnish 82 . The mounting portion 23 has a mounting portion main body 24 that protrudes from the extending wall portion 22 along the arrangement direction L, and a support protrusion 26 that is folded back inward from the tip of the mounting portion main body 24. The support protrusion 26 is inclined so that it approaches the extending wall portion 22 as it moves inward.

[0034] The elastic engagement portion 25 of the base portion 20 is made of a softer material than the side wall portion 21, the extending wall portion 22, the mounting portion main body 24, and the support protrusion 26. <Clearance Lip 30> As shown in FIG. 2, the parting lip 30 seals a parting gap V between the window glass 91 and the pillar garnish 82.

[0035] The parting lip 30 extends from the outer end of the extension wall portion 22 toward the edge of the window glass 91. The parting lip 30 has a base end portion 31 and a tip end portion 32 extending from the tip of the base end portion 31.

[0036] The base end portion 31 extends along the arrangement direction L. The distal end portion 32 extends in a curved manner so that the further away from the proximal end portion 31 in the arrangement direction L, the more inward the distal end portion 32 is positioned.

[0037] A base end thin portion 33 is provided on the inner surface of the base end portion 31 . A tip-side thin portion 34 is provided on the inner surface of the parting lip 30, closer to the tip side than the base-side thin portion 33. The thickness of the tip-side thin portion 34 is thinner than the thickness of the base-side thin portion 33.

[0038] The thickness of the parting lip 30 between the base end thin portion 33 and the tip end thin portion 34 is made larger than that of the other portions. A sliding portion 35 is provided on the outer surface of the parting lip 30 at a portion that slides against the window glass 91.

[0039] The part of the parting lip 30 other than the sliding portion 35 is formed of a material that is softer than the base portion 20. The sliding portion 35 is formed of a material that is harder than the part of the parting lip 30 other than the sliding portion 35.

[0040] <First seal lip 40> As shown in FIG. 2, the first seal lip 40 extends outward from the side wall portion 21. The first seal lip 40 has a first base end portion 41 extending from the side wall portion 21 and a first tip end portion 42 extending from the tip of the first base end portion 41.

[0041] The first base end portion 41 extends from the side wall portion 21 so as to be farther away from the extending wall portion 22 in the arrangement direction L as it extends outward. The first tip portions 42 extend so as to approach the extending wall portions 22 in the arrangement direction L as they move outward.

[0042] The first seal lip 40 is provided with a first thin portion 43, which is a partial reduction in thickness of the first seal lip 40, on a side surface (the rear surface in FIG. 2 ) facing the second seal lip 50. The first thin portion 43 is provided between a first base end portion 41 and a first tip end portion 42. In other words, the portion of the first seal lip 40 closer to the base end than the first thin portion 43 is the first base end portion 41, and the portion closer to the tip end than the first thin portion 43 is the first tip end portion 42.

[0043] A sliding portion 44 is provided on the outer surface of the first seal lip 40 at a portion that slides against the window glass 91 . The sliding portion 44 is formed of a material that is harder than the other portions of the first seal lip 40. The sliding portion 44 of the present embodiment is formed of the same material as the sliding portion 35 of the parting lip 30.

[0044] <Second seal lip 50> As shown in FIG. 2, the second seal lip 50 extends outward from a portion of the side wall portion 21 that is closer to the extending wall portion 22 than the first seal lip 40 is.

[0045] The second seal lip 50 has a second base end portion 51 extending from the side wall portion 21 and a second tip end portion 52 extending from the tip of the second base end portion 51. The thickness of the second base end portion 51 is preferably increased toward the base end.

[0046] The second tip portions 52 extend so as to approach the extending wall portions 22 in the arrangement direction L as they move outward. A protrusion 55 that protrudes toward the window glass 91 in the thickness direction of the second seal lip 50 is provided at the tip of the second tip portion 52.

[0047] The second seal lip 50 is provided with a second thin portion 53, which is a partial reduction in thickness of the second seal lip 50, on a side surface (the rear surface in FIG. 2 ) facing the extending wall portion 22. The second thin portion 53 is provided between the second base end portion 51 and the second tip end portion 52. That is, the portion of the second seal lip 50 closer to the base end than the second thin portion 53 is the second base end portion 51, and the portion closer to the tip end than the second thin portion 53 is the second tip end portion 52.

[0048] The second thin portion 53 is preferably located more inward than the first thin portion 43 in the inward-outward direction W. A sliding portion 54 is provided on the outer surface of the second seal lip 50 at a portion that slides against the window glass 91 .

[0049] The sliding portion 54 is formed of a material that is harder than the other portions of the second seal lip 50. The sliding portion 54 in this embodiment is formed of the same material as the sliding portion 35 of the parting lip 30 and the sliding portion 44 of the first seal lip 40.

[0050] Next, the operation of this embodiment will be described. 3, in the parting seal member 10 of this embodiment, the first seal lip 40 and the second seal lip 50 each abut against the inner surface of the window glass 91. Therefore, compared to a conventional parting seal member having only one seal lip, it is possible to suppress outside noise from entering the vehicle interior through the parting gap V.

[0051] However, by providing the first seal lip 40 and the second seal lip 50, the size of the parting seal member 10 in the arrangement direction L may become large. To address this issue, it is conceivable to reduce the distance between the first seal lip 40 and the second seal lip 50 in the arrangement direction L. However, in this case, when the first seal lip 40 abuts against the inner surface of the window glass 91 and collapses, it may interfere with the second seal lip 50, which could prevent the first seal lip 40 or the second seal lip 50 from abutting properly against the window glass 91. As a result, a new problem arises in that the sealing properties of the first seal lip 40 and the second seal lip 50 are impaired.

[0052] In this regard, as shown in Fig. 3, in the parting seal member 10 of this embodiment, a convex portion 55 is provided at the tip of the second tip portion 52 of the second seal lip 50. Therefore, when the convex portion 55 abuts against the inner surface of the window glass 91, the second seal lip 50 will fall significantly toward the base portion 20 by the amount of protrusion of the convex portion 55. This prevents the first seal lip 40 from interfering with the second seal lip 50 when it falls (this is the first effect).

[0053] On the other hand, as shown in Fig. 4, the parting seal member 110 of the comparative example differs from the parting seal member 10 of the present embodiment only in that no protrusion is provided at the tip of the second tip portion 152 of the second seal lip 150. Note that in Fig. 4, the same components as those of the present embodiment are given the same reference numerals, and corresponding components are given the reference numeral "1**", which is obtained by adding 100 to the reference numeral ** of the component of the present embodiment, thereby omitting redundant explanations.

[0054] In the parting seal member 110 of the comparative example, in a natural state, the distance between the first seal lip 40 and the second seal lip 50 in the arrangement direction L is the same as that of the parting seal member 10 of the present embodiment. However, when the first seal lip 40 collapses, it interferes with the second seal lip 50.

[0055] As shown in FIG. 5, in the parting seal member 10 of this embodiment, the thickness of the tip-side thin portion 34 of the parting lip 30 is thinner than the thickness of the base-side thin portion 33. With this configuration, the parting lip 30 is more likely to collapse from the tip-side thin portion 34. Therefore, the amount of collapse of the parting lip 30 is smaller than when the tip-side thin portion 34 is not included, i.e., when collapse occurs from only the base-side thin portion 33, as in the case of the comparative parting seal member 110 shown in FIG. 6. This reduces the step formed between the decorative surface of the parting lip 30 and the outer surface of the window glass 91, thereby improving the flushness of the decorative surface of the pillar 80, the decorative surface of the parting lip 30, and the outer surface of the window glass 91 (the second effect).

[0056] Next, the effects of this embodiment will be described. (1) The tip of the second tip portion 52 is provided with a protrusion 55 that protrudes toward the window glass 91 in the thickness direction of the second seal lip 50.

[0057] According to this configuration, the first effect described above is achieved, and therefore it is possible to suppress the intrusion of outside noise while suppressing an increase in the size of the parting seal member 10. (2) The second thin-walled portion 53 is located more inward than the first thin-walled portion 43 in the inward-outward direction W. This makes it possible to reduce the amount of inclination of the first tip portion 42 starting from the first thin-walled portion 43, while increasing the amount of inclination of the second tip portion 52 starting from the second thin-walled portion 53. This reduces the gap between the first seal lip 40 and the second seal lip 50 in the arrangement direction L, and further prevents the first seal lip 40 from interfering with the second seal lip 50 when it falls.

[0058] (3) Providing the second thin-walled portion 53 makes the second seal lip 50 more likely to bend starting from the second thin-walled portion 53. However, if the rigidity of the second base end portion 51 of the second seal lip 50 is low, the second seal lip 50 may be pressed by the window glass 91 and collapse toward the first seal lip 40.

[0059] In this regard, according to the above configuration, the thickness of the second base end portion 51 is made greater toward the base end side, thereby increasing the rigidity of the second base end portion 51 and making it possible to prevent the second seal lip 50 from collapsing toward the first seal lip 40 side.

[0060] (4) The first base end portion 41 extends from the side wall portion 21 so as to be farther away from the extending wall portion 22 in the arrangement direction L as it extends outward. With this configuration, the position of the first thin-walled portion 43 can be spaced apart from the second seal lip 50 in the arrangement direction L. This makes it possible to further reduce the gap between the base end of the first seal lip 40 and the base end of the second seal lip 50 in the arrangement direction L, while increasing the gap between the first tip end 42 of the first seal lip 40 and the second tip end 52 of the second seal lip 50. Therefore, when the first seal lip 40 falls over, interference with the second seal lip 50 can be further suppressed.

[0061] (5) The thickness of the tip-side thin portion 34 of the parting lip 30 is thinner than the thickness of the base-side thin portion 33 . According to this configuration, the second effect described above is achieved, thereby improving the appearance of the vehicle.

[0062] (6) The thickness of the parting lip 30 between the base end thin portion 33 and the tip end thin portion 34 is greater than that of the other portions. With this configuration, the portion of the parting lip 30 between the base end thin portion 33 and the tip end thin portion 34 is less likely to deform. This makes it easier for the parting lip 30 to achieve the above-mentioned effect of collapsing starting from the tip end thin portion 34. This more reliably improves the flushness of the decorative surface of the pillar 80, the decorative surface of the parting lip 30, and the outer surface of the window glass 91.

[0063] <Modification> This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0064] At least one of the sliding portions 35, 44, 54 may be omitted. For example, the thickness of the parting lip 30 between the base end thin portion 33 and the tip end thin portion 34 may be the same as that of the other portions.

[0065] The thickness of the thin portion 34 on the tip side of the parting lip 30 may be the same as the thickness of the thin portion 33 on the base side. The parting lip 30 does not have to have the thin-walled portion 34 on the tip side.

[0066] The parting lip 30 does not have to have the base end thin portion 33. The first seal lip 40 may be configured such that the position of the first base end portion 41 in the arrangement direction L is constant throughout the entire inward / outward direction W.

[0067] The thickness of the second base end portion 51 of the second seal lip 50 can also be made constant. The second thin-walled portion 53 of the second seal lip 50 may be located at the same position as the first thin-walled portion 43 of the first seal lip 40 in the inward / outward direction W, or may be located outward of the first thin-walled portion 43 of the first seal lip 40.

[0068] The first thin portion 43 and the second thin portion 53 may be omitted. The parting seal member 10 may also be embodied as a seal for the parting gap between the rear door window glass and the pillar 80.

[0069] (Note on the means to solve the problem) The means for solving the above problems include the following (Supplementary Items 1 to 3) which are technical ideas that can be grasped from the above embodiment and its modifications.
