[0006] [Patent Document 1] Japanese Patent Application Publication No. 2018-52253 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in roof side weatherstrips where the bottom portion (hereinafter referred to as the base portion) is made of a harder material than the seal portion, it is difficult to deflect the base portion, and therefore, there is a need for improved assembly by pushing the base portion from below. [Means for solving the problem]

[0008] Various aspects of a vehicle roof side weatherstrip and an assembly structure for a vehicle roof side weatherstrip that solves the above problems will be described below. [Aspect 1] A vehicle roof side weatherstrip adapted for use in a vehicle equipped with a sashless door, the vehicle roof side weatherstrip comprising: a mounting base having a base portion facing a bottom wall of a retainer fixed to a roof side portion of the vehicle; and a seal portion integrally formed with the mounting base from a material softer than the base portion, forming a hollow portion together with the mounting base, and providing a seal between the mounting base and an upper edge of a window glass provided in the sashless door so as to be able to rise and fall, When the inside and outside of the vehicle in the inward / outward direction through the window glass are defined as the inside and outside, respectively, and the upper and lower sides of the window glass in the ascending / descending direction are defined as the upper and lower, respectively, The mounting base is an inner engagement portion provided on the inside of the base portion, protruding inward, and engaging from above with an inner engagement protrusion provided on an inner side wall of the retainer; an outer engagement portion provided on the outside of the base portion, protruding outward, and engaging from above with an outer engagement protrusion provided on an outer side wall of the retainer; Between the outer engaging portion and the base portion, an outer guide surface is provided which faces the outer side wall of the retainer and is inclined so as to be positioned more inward as it goes upward. Vehicle roof side weather strip.

[0009] With this configuration, when the mounting base is pushed into the retainer from below to assemble it, the outer guide surface slides over the outer engagement protrusion of the retainer, guiding the pushing of the mounting base. This makes it easier for the outer engagement portion of the mounting base to climb over the outer engagement protrusion of the retainer. Therefore, the ease of assembly by pushing from below is improved.

[0010] [Aspect 2] The outer end of the outer engagement portion is formed of a material softer than the base portion. A vehicle roof side weather strip according to embodiment 1.

[0011] In order to suppress rattle of the mounting base in the inward and outward directions, it is conceivable to make the mounting base abut against both the inner side wall and the outer side wall of the retainer. However, since there are manufacturing variations in the roof side weatherstrip and the retainer, it is difficult to abut the mounting base against both the inner side wall and the outer side wall of the retainer.

[0012] In this regard, with the above-described configuration, the outer end of the outer engagement portion is formed of a softer material than the base portion, so that by pressing the outer end against the inner sidewall of the retainer and causing elastic deformation, the mounting base can be brought into contact with both the inner sidewall and the outer sidewall of the retainer, thereby suppressing rattle of the mounting base in the inward and outward directions.

[0013] [Aspect 3] the mounting base has a lip portion that is continuous with an outer end of the base bottom portion and is pressed against the bottom wall of the retainer, The lip portion is formed of a softer material than the base portion. A roof side weather strip for a vehicle according to the first or second aspect.

[0014] According to this configuration, the lip portion connected to the outer end of the base portion is pressed against the bottom wall of the retainer, so that the orientation of the mounting base portion relative to the retainer can be stabilized. Furthermore, because the lip portion is made of a softer material than the base portion, even if the outer engaging protrusion interferes with the lip portion when the mounting base is pressed onto the retainer from below, the lip portion elastically deforms and easily overcomes the outer engaging protrusion of the retainer. Therefore, the provision of the lip portion can prevent the roof side weatherstrip from being pressed into place from below, thereby preventing the ease of assembly from being impaired.

[0015] [Aspect 4] A vehicle roof side weatherstrip assembly structure including the vehicle roof side weatherstrip according to any one of aspects 1 to 3 and the retainer, the vehicle roof side weatherstrip being assembled to the retainer, The retainer is the bottom wall fixed to the roof side portion; an inner sidewall extending downward from an inner end of the bottom wall and having the inner engagement projection; an outer sidewall extending downward from an outer end of the bottom wall and having the outer engagement projection; Assembly structure for vehicle roof side weather strip.

[0016] According to this configuration, the same effects as those of the vehicle roof side weather strips described in the first to third aspects can be achieved. [Aspect 5] When the base portion is in contact with the bottom wall, a gap is provided between the inner engaging portion and the inner engaging projection in the ascending / descending direction, and a gap is provided between the outer engaging portion and the outer engaging projection in the ascending / descending direction. 5. An assembly structure of a vehicle roof side weather strip according to embodiment 4.

[0017] Incidentally, the roof side weatherstrip can also be assembled by inserting it along the extending direction of the retainer from one end to the other end in the extending direction of the retainer. In this regard, with the above-described configuration, a gap in the vertical direction is formed between the mounting base and the retainer, which reduces sliding resistance when assembling the mounting base along the extension direction of the retainer, thereby improving the ease of assembling the roof side weatherstrip along the extension direction of the retainer. [Effects of the Invention]

[0018] According to the present invention, the ease of assembling the roof side weather strip by pushing it in from below is improved. [Brief explanation of the drawings]

[0027] The inner side wall 72 has an inner engagement protrusion 73 that protrudes outward. The inner engagement protrusion 73 is formed by bending the inner side wall 72 outward. The outer side wall 74 has an outer engagement protrusion 75 that protrudes inward. The outer engagement protrusion 75 is located lower than the inner engagement protrusion 73. The outer engagement protrusion 75 extends upward as the outer side wall 74 is folded inward. The outer engagement protrusion 75 is inclined so that it is positioned more inward as it approaches the upper side.

[0028] The retainer 70 is formed from, for example, a metal plate material. Next, a detailed description will be given of each component of the roof side weatherstrip 10. Note that the shape of each component of the roof side weatherstrip 10 will be described in terms of the shape when not in contact with the window glass 91 (hereinafter referred to as the natural state).

[0029] <Mounting base 20> As shown in FIG. 5, the mounting base 20 includes a base portion 21, an inner engagement portion 22, an inner lip portion 23, an outer engagement portion 24, an inner abutment portion 27, an outer abutment portion 28, and an outer lip portion 29.

[0030] The base portion 21 extends in the inward / outward direction W and faces the bottom wall 71 of the retainer 70. The upper surface of the base portion 21 is provided with a recess 21a that allows the head of the clip 81 to escape. The inner end of the base portion 21 is provided with an abutment surface 21b that abuts against the bottom wall 71 of the retainer 70.

[0031] The inner engagement portion 22 is provided on the inside of the base portion 21, protrudes inward, and is configured to engage from above with the inner engagement protrusion 73 of the retainer 70. A gap is formed between the inner engagement portion 22 and the inner side wall 72 of the retainer 70.

[0032] The inner lip portion 23 is provided below the inner engagement portion 22 and protrudes inward as it goes downward. The inner lip portion 23 abuts against the inclined surface of the inner engagement projection 73.

[0033] The inner lip portion 23 is formed of a softer material than the base portion 21. The soft material forming the inner lip portion 23 is preferably a sponge material made of synthetic resin, for example.

[0034] The outer engaging portion 24 is provided on the outside of the base portion 21, protrudes outward, and is configured to engage with the outer engaging projection 75 of the retainer 70 from above. The outer end 25 of the outer engaging portion 24 is formed of a material that is softer than the base portion 21. The soft material that forms the outer end 25 is preferably a sponge material made of synthetic resin, for example.

[0035] An outer guide surface 26 is provided between the outer engagement portion 24 and the base portion 21. The outer guide surface 26 faces the outer side wall 74 of the retainer 70 and is inclined so that the upper portion is positioned more inward. A gap is formed between the outer guide surface 26, other than the outer end portion 25, and the outer side wall 74 of the retainer 70.

[0036] Between the inner engaging portion 22 and the inner lip portion 23, an inner abutment portion 27 that abuts against the tip of the inner engaging projection 73 of the retainer 70 is provided. An outer abutment portion 28 that abuts against the inclined surface of the outer engagement protrusion 75 of the retainer 70 is provided below the outer engagement portion 24. The outer abutment portion 28 has an inclined surface that follows the inclined surface of the outer engagement protrusion 75.

[0037] The outer lip portion 29 is continuous with the outer end of the base portion 21 and is pressed against the protrusion portion 76 of the bottom wall 71 of the retainer 70. The outer lip portion 29 is formed of a softer material than the base portion 21. A preferred soft material for forming the outer lip portion 29 is a sponge material made of synthetic resin, for example.

[0038] <Seal part 30> As shown in Fig. 2, the seal portion 30 is integrally molded with the mounting base 20 from a material softer than the base portion 21. The seal portion 30 and the mounting base 20 form a hollow portion 31. The seal portion 30 is formed from a material softer than the base portion 21. The soft material forming the seal portion 30 is preferably a sponge material made of synthetic resin, for example.

[0039] <Opening Weather Strip 40> As shown in FIGS. 2 and 6, an opening weatherstrip 40 is attached to the roof side portion 80 on the inner side of the retainer 70 to seal the gap with the inner surface of the window glass 91.

[0040] The opening weatherstrip 40 has a mounting portion 41 that is attached to the roof side portion 80 and a hollow seal portion 42 that protrudes outward from the mounting portion 41. Next, with reference to Figs. 3 to 5, a procedure for assembling the mounting base portion 20 of the roof side weather strip 10 by pushing it into the retainer 70 from below will be described.

[0041] As shown in Figure 3, the worker positions the inner engagement portion 22 of the roof side weatherstripping 10 inside the inner engagement protrusion 73 of the retainer 70 and brings the outer lip portion 29 into contact with the outer engagement protrusion 75. Then, when the mounting base 20 is pushed toward the bottom wall 71 of the retainer 70, the outer lip portion 29 elastically deforms and moves over the outer engagement protrusion 75.

[0042] As shown in FIG. 4, when the mounting base 20 is further pushed in, the outer guide surface 26 slides on the outer engagement protrusion 75, thereby guiding the mounting base 20 as it is pushed in. Then, as shown in FIG. 5, the mounting base 20 is assembled to the retainer 70.

[0043] Next, the operation of this embodiment will be described. When the mounting base 20 is pushed into the retainer 70 from below to assemble it, the outer guide surface 26 slides over the outer engaging protrusion 75 of the retainer 70, thereby guiding the pushing of the mounting base 20. This makes it easier for the outer engaging portion 24 of the mounting base 20 to climb over the outer engaging protrusion 75 of the retainer 70 (this is the first effect).

[0044] The roof side weatherstrip 10 can also be assembled by inserting it from one end of the retainer 70 in the extending direction to the other end in the extending direction. 6, when the base portion 21 is in contact with the bottom wall 71, a gap is formed between the inner engaging portion 22 and the inner engaging protrusion 73 in the lifting direction Z. Also, a gap is formed between the outer engaging portion 24 and the outer engaging protrusion 75 in the lifting direction Z.

[0045] In this way, a gap is formed between the mounting base 20 and the retainer 70 in the lifting direction Z, reducing sliding resistance when assembling the mounting base 20 along the extension direction of the retainer 70 (above, the second effect).

[0046] Next, the effects of this embodiment will be described. (1) Between the outer engaging portion 24 and the base portion 21, there is provided an outer guide surface 26 that faces the outer side wall 74 of the retainer 70 and is inclined so that the upper portion is positioned more inward.

[0047] According to this configuration, the first effect described above is achieved, and the ease of assembling the roof side weather strip 10 by pushing it from below is improved. (2) In order to suppress rattle of the mounting base 20 in the inward / outward direction W, it is conceivable to make the mounting base 20 abut against both the inner side wall 72 and the outer side wall 74 of the retainer 70 .

[0048] However, since there are manufacturing variations in the roof side weatherstrip 10 and the retainer 70, it is difficult to abut the mounting base 20 against both the inner side wall 72 and the outer side wall 74 of the retainer 70.

[0049] In this regard, according to the above configuration, the outer end portion 25 of the outer engaging portion 24 is formed of a softer material than the base portion 21. Therefore, by pressing the outer end portion 25 against the inner side wall 72 of the retainer 70 and causing it to elastically deform, the mounting base 20 can be brought into contact with both the inner side wall 72 and the outer side wall 74 of the retainer 70. Therefore, rattling of the mounting base 20 in the inward / outward direction W can be suppressed.

[0050] (3) The outer lip portion 29 connected to the outer end of the base portion 21 is pressed against the bottom wall 71 of the retainer 70, so that the posture of the mounting base portion 20 relative to the retainer 70 can be stabilized. Furthermore, the outer lip portion 29 is formed from a softer material than the base portion 21. Therefore, when the mounting base 20 is pressed onto the retainer 70 from below to assemble it, even if the outer engaging protrusion 75 interferes with the outer lip portion 29, the outer lip portion 29 will easily deform and overcome the outer engaging protrusion 75 of the retainer 70. Therefore, the provision of the outer lip portion 29 can prevent the ease of assembly of the roof side weatherstrip 10 from being impaired by pressing from below.

[0051] (4) When the seal portion 30 is pressed upward by the upper edge of the window glass 91, there is a gap in the lifting direction Z between the inner engagement portion 22 and the inner engagement protrusion 73, and there is a gap in the lifting direction Z between the outer engagement portion 24 and the outer engagement protrusion 75.

[0052] According to this configuration, the second effect described above is achieved, and the ease of assembling the roof side weatherstrip 10 along the extending direction of the retainer 70 is improved. <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.

[0053] The inner lip portion 23 may be formed from the same material as the base portion 21. The inner lip portion 23 may also be omitted. When the seal portion 30 is pressed upward by the upper edge of the window glass 91, there does not need to be a gap in the lifting direction Z between the inner engagement portion 22 and the inner engagement protrusion 73. Also, there does not need to be a gap in the lifting direction Z between the outer engagement portion 24 and the outer engagement protrusion 75.

[0054] The outer lip portion 29 may be formed from the same material as the base portion 21. Also, the outer lip portion 29 may be omitted. The outer end portion 25 may be made of the same material as the base portion 21 . [Explanation of symbols]
