Description

Technical Field

[0001] The present invention relates to a weatherstrip attached to the periphery of a vehicle body opening of a sashless door of an automobile and sealing the space between the periphery of the vehicle body opening and the periphery of a door glass.

Background Art

[0002] Improving the quietness of vehicles such as automobiles enhances the comfort of passengers, so the appeal for improving product power is high. Also, in popular electric vehicles, since the conventionally installed engine is removed, the main remaining noises due to the disappearance of the engine noise are the road noise and the wind noise, which become 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 to make 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. 8 shows the technique disclosed in Patent Document 1, which is 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 a thick portion 330 that protrudes inward 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, when the thick portion 330 with high hardness contacts the door glass 600, it is possible to efficiently propagate the vibration energy of the door glass 600 to the glass run 100 by using impedance matching and reduce the vibration.

[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 sandwiches the door glass 600 between the door glass 600 and the door frame groove portion 500, it is possible to increase 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, thereby reducing vibration.

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

[0008] Incidentally, some automobiles, due to design requirements, have frameless doors that eliminate the door frame (door sash), allowing only the door glass to move freely above the beltline. In other words, on the side of the car, above the beltline, only the door glass is visible.

[0009] The reduction of door glass vibrations related to the weatherstrip, which is attached to the periphery of the body opening of the frameless door and seals the space between the periphery of the body opening and the periphery of the door glass, has not yet been sufficiently considered. [Means for solving the problem]

[0010] The present invention relates to a weatherstrip attached to the periphery of the body opening of a vehicle body with a frameless door, and provides a weatherstrip that exhibits the effect of reducing vibration by utilizing impedance matching with the door glass.

[0011] To solve the above problems, the first aspect of the present invention is a weatherstrip that is attached to the periphery of the body opening of a vehicle body of a car with a frameless door and seals the space between the periphery of the body opening and the periphery of the door glass, wherein the weatherstrip comprises a mounting base attached to the periphery of the body opening and a sealing portion that abuts against the door glass, the sealing portion being hollow or lip-shaped, the sealing portion comprising a hard sealing portion, and the door glass abutting against the hard sealing portion.

[0012] In a first aspect of the present invention, the weatherstrip comprises a mounting base attached to the peripheral edge of the vehicle body opening and a sealing portion that contacts the door glass. The sealing portion is hollow or lip-shaped and includes a hard portion. The door glass contacts the hard portion, and as the sealing portion deforms, it seals the space between the peripheral edge of the vehicle body opening and the door glass. The hard portion also increases the rigidity of the weatherstrip, and by utilizing impedance matching with the door glass, the vibration energy of the door glass can be efficiently transmitted to the hard portion of the sealing portion. As a result, even in automobiles with frameless doors, vibrations of the door glass can be reduced by weatherstrips.

[0013] Here, the hardened portion of the seal is the part that is made of a material with a higher hardness than the material that makes up the seal excluding the hardened portion.

[0014] Furthermore, the "rigidity of the weatherstrip" is expressed as the increase in the reaction force from the trim portion in response to the change in the pressure point when the part of the weatherstrip that contacts the door glass is pressed. Therefore, by forming a rigid part in the seal portion, the slope (gradient) in the relationship between displacement and reaction force becomes larger.

[0015] A second aspect of the present invention is that, in the first aspect, the seal portion is hollow, the mounting base portion comprises a mounting base rigid portion and a mounting base lip connected to the mounting base rigid portion and projecting inward toward the hollow portion, the mounting base lip portion comprises a mounting base lip rigid portion connected to the mounting base rigid portion, and the seal portion rigid portion is a weatherstrip that abuts against the mounting base lip rigid portion.

[0016] In a second aspect of the present invention, the seal portion is hollow, and the mounting base portion comprises a mounting base rigid portion and a mounting base lip connected to the mounting base rigid portion and projecting inward toward the hollow portion. The mounting base lip comprises a mounting base lip rigid portion connected to the mounting base rigid portion, and the seal portion rigid portion abuts against the mounting base lip rigid portion. Therefore, by utilizing impedance matching with the door glass, the vibration energy of the door glass transmitted to the seal portion rigid portion can be efficiently dissipated to the mounting base rigid portion via the mounting base lip rigid portion. As a result, in automobiles with frameless doors, vibration of the door glass can be further reduced by the weatherstrip.

[0017] Here, the hardened part of the mounting base refers to the portion made of a material with higher hardness than the material that makes up the mounting base excluding the hardened part of the mounting base, and the hardened part of the mounting base lip refers to the portion made of a material with higher hardness than the material that makes up the mounting base lip excluding the hardened part of the mounting base lip.

[0018] Furthermore, from the viewpoint of vibration energy propagation through impedance matching, it is desirable that the hardness of the seal portion, the hard portion of the mounting base lip, and the hard portion of the mounting base be the same or close in hardness.

[0019] Furthermore, by bringing the rigid part of the mounting base into contact with the flange or retainer on the peripheral edge side of the vehicle body opening to which the mounting base is attached, the vibration energy of the door glass can be further dissipated from the rigid part of the mounting base towards the peripheral edge side of the vehicle body opening.

[0020] In the third aspect of the present invention, in the first aspect, the seal part has a hollow shape, and between the mounting base and the seal part, there is an outer vehicle side wall. The outer vehicle side wall has a hard portion of the outer vehicle side wall that is exposed to the inside of the vehicle. The hard portion of the seal part is a weatherstrip that abuts against the hard portion of the outer vehicle side wall.

[0021] In the third aspect of the present invention, the seal part has a hollow shape, and between the mounting base and the seal part, there is an outer vehicle side wall. The outer vehicle side wall has a hard portion of the outer vehicle side wall part that is exposed to the inside of the vehicle. Since the hard portion of the seal part abuts against the hard portion of the outer vehicle side wall, by using impedance matching with the door glass, the vibration energy of the door glass propagated to the hard portion of the seal part can be dissipated to the outer vehicle side wall through the hard portion of the outer vehicle side wall. As a result, in a sashless door vehicle, the vibration of the door glass can be further reduced by the weatherstrip.

[0022] Here, the hard portion of the outer vehicle side wall is a portion formed of a material having a higher hardness than the material constituting the outer vehicle side wall excluding the hard portion of the outer vehicle side wall.

[0023] In the fourth aspect of the present invention, in the third aspect, the hard portion of the outer vehicle side wall is a weatherstrip formed to penetrate to the outside of the vehicle.

[0024] In the fourth aspect of the present invention, since the hard portion of the outer vehicle side wall is formed to penetrate to the outside of the vehicle, the hard portion of the outer vehicle side wall can be brought into contact with a flange or a retainer on the peripheral edge side of the vehicle body opening to attach the mounting base, and the vibration energy of the door glass can be further dissipated from the hard portion of the outer vehicle side wall to the peripheral edge side of the vehicle body opening. As a result, in a sashless door vehicle, the vibration of the door glass can be further reduced by the weatherstrip.

[0025] In the fifth aspect of the present invention, in the first aspect, the mounting base has a hard portion of the mounting base, the seal part has a lip shape, the hard portion of the seal part is formed from the contact region to the tip of the seal part of the seal part, and the hard portion of the seal part is a weatherstrip that abuts against the hard portion of the mounting base.

[0026] In the fifth aspect of the present invention, the mounting base includes a hard portion of the mounting base, the sealing portion has a lip shape, the hard portion of the sealing portion is formed from the contact region to the tip end portion of the sealing portion of the sealing portion, and since the hard portion of the sealing portion contacts the hard portion of the mounting base, the vibration energy of the door glass propagated to the hard portion of the sealing portion can be dissipated to the hard portion of the mounting base. As a result, in an automobile with a sashless door, the vibration of the door glass can be further reduced by the weatherstrip.

[0027] The sixth aspect of the present invention is a weatherstrip attached to the periphery of a vehicle body opening of an automobile body of a sashless door, for sealing between the periphery of the vehicle body opening and the peripheral portion of the door glass, the weatherstrip including a mounting base attached to the periphery side of the vehicle body opening, a sealing portion contacting the door glass, an inner vehicle side wall, and a lip hard portion connecting to at least one of the mounting base and the inner vehicle side wall, the sealing portion having a hollow shape including a bent portion of the sealing portion, and the bent portion of the sealing portion being a weatherstrip contacting the door glass and the lip hard portion.

[0028] In the sixth aspect of the present invention, since the weatherstrip has a hollow shape and includes a bent portion of the sealing portion, a part of the sealing portion becomes a lump shape due to the bent portion of the sealing portion, and the rigidity increases. Then, by the contact between the bent portion of the sealing portion with increased rigidity and the door glass, the vibration energy of the door glass can be efficiently propagated to the bent portion of the sealing portion using impedance matching. Also, since the bent portion of the sealing portion contacts the lip hard portion connecting to at least one of the mounting base and the inner vehicle side wall, the vibration energy propagated to the bent portion of the sealing portion can be dissipated to the mounting base or the inner vehicle side wall via the lip hard portion. As a result, in an automobile with a sashless door, the vibration of the door glass can be reduced by the weatherstrip.

[0029] Here, the lip hard portion is formed of a material having a higher hardness than the material constituting the sealing portion.

[0030] A seventh aspect of the present invention is a weatherstrip in which, in the sixth aspect, at least one of the mounting base and the inner side wall of the vehicle is provided with a base-side hard portion that connects to the lip hard portion.

[0031] In a seventh aspect of the present invention, at least one of the mounting base and the inner side wall is provided with a base-side rigid portion connected to the lip rigid portion. This allows vibration energy transmitted to the lip rigid portion to be efficiently dissipated to the mounting base side or the inner side wall side via the base-side rigid portion. As a result, in automobiles with frameless doors, vibration of the door glass can be further reduced by the weatherstrip. Furthermore, by bringing the hard base portion into contact with the peripheral edge of the vehicle body opening, the vibration energy transmitted to the hard lip portion can be more efficiently dissipated to the peripheral edge of the vehicle body opening via the hard base portion.

[0032] Here, the hardened base portion refers to the part made of a material with higher hardness than the materials that make up the mounting base and the inner side wall of the vehicle. [Effects of the Invention]

[0033] A weatherstrip is attached to the periphery of the body opening of a car body with a frameless door, and seals the space between the periphery of the body opening and the periphery of the door glass. The weatherstrip comprises a mounting base attached to the periphery of the body opening and a sealing portion that contacts the door glass. The sealing portion is hollow or lip-shaped and includes a rigid sealing portion. The door glass contacts the rigid sealing portion, and as the sealing portion deforms, it seals the space between the periphery of the body opening and the door glass. The rigid sealing portion also increases the rigidity of the weatherstrip, and by utilizing impedance matching with the door glass, the vibrational energy of the door glass can be efficiently transmitted to the rigid sealing portion. As a result, even in automobiles with frameless doors, door glass vibration can be reduced by weatherstrips. [Brief explanation of the drawing]

[Figure 8] This is a cross-sectional view showing a conventional glass run mounting structure (Patent Document 1). [Modes for carrying out the invention]

[0035] A first embodiment of the present invention will be described with reference to Figures 1 and 2. Figure 1 is a left side view of an automobile. The weatherstrip 10 of the present invention is used in automobiles with frameless doors. Above the beltline portion of both the front and rear doors, which are the side doors 1 of the automobile, there is no door sash (door frame), and the door glass 3 is provided over almost the entire surface, and the door glass 3 can be raised and lowered from the door 1. The present invention is applicable not only to the left front door, but also to the right front door and the left and right rear doors. Furthermore, Figure 1 is also used in the second to fifth embodiments described later.

[0036] Figure 2 shows a first embodiment of the present invention and is a cross-sectional view AA of Figure 1. Figure 2 shows the roof side of the peripheral edge 4 of the vehicle body opening (Figure 1), and in the weatherstrip 10, it corresponds to the upper edge of the door glass 3. Also, Figure 2 shows the door glass 3 in the closed position.

[0037] The roof side of the vehicle body bends inward from the roof near the periphery 4 of the vehicle body opening, forming the outer panel on the roof side. This outer panel forms a flat section 4a at the entrance portion of the periphery 4 of the vehicle body opening, which houses the upper edges of the door glass 3 of the front and rear doors. A retainer 2 is assembled to the lower surface of this flat section 4a. The retainer 2 is made by bending steel.

[0038] The interior side of the flat section 4a is provided with a downwardly curved vertical section 4b, which is formed with a shift inward from the middle towards the tip, and a second weatherstrip 11 is attached to the tip. A detailed explanation of the second weatherstrip 11 is omitted, but it is provided with a second sealing section 45, which contacts the interior side surface 3c of the door glass 3.

[0039] The retainer 2 has a roughly L-shaped cross-section, and both ends, namely the inner end and the outer, lower end, are provided with a U-shaped inner groove 2a at the inner end and a U-shaped outer groove 2b at the outer, lower end, with the inner tip portion protruding inward and upward. Furthermore, the corners are equipped with engaging portions 2c that connect a V-shaped groove in the vertical direction of the vehicle and a mountain-shaped protrusion that extends upward in the width direction of the vehicle.

[0040] The weatherstrip 10 comprises a mounting base 20, an outer side wall 30, and a sealing portion 40. The outer side wall 30 is connected to the mounting base 20. The sealing portion 40 has an inner end 41 connected to the mounting base 20 and an outer end 42 connected to the outer side wall 30, forming a hollow portion 43 that bulges downward.

[0041] The mounting base 20 comprises a flat side portion 21 facing the flat portion 4a of the peripheral edge 4 of the vehicle body opening, and an outer portion 22 connected to the flat side portion 21 and extending linearly outward and downward.

[0042] Furthermore, the upper tip portion on the interior side of the flat side portion 21 is provided with an interior projection 23 that protrudes inward and an interior upward projection 24 that protrudes upward. Furthermore, the outer end portion of the flat side portion 21 is provided with an outer projection 25 that protrudes outward from the vehicle and an outer upward projection 26 that protrudes upward from the vehicle.

[0043] The outer side wall 30 is connected to the outer portion 22 of the mounting base 20 and extends downward. Furthermore, near the lower tip, it has a bulge 31 that bulges linearly outward and downward. The outer end 42 of the seal portion 40 is connected to the tip of the bulge 31.

[0044] The outer portion 22 of the mounting base 20 is provided with a mounting base lip 27 that extends inward and downward near the connection point with the outer side wall 30. The mounting base lip 27 is curved in a convex shape downward. Furthermore, a thin-walled lip portion 28 is provided on the upper side of the base of the mounting base lip 27.

[0045] The area of ​​the mounting base 20 including the in-vehicle projection 23 and the in-vehicle upper projection 24, and the area excluding the out-vehicle projection 25, and the area of ​​the seal portion 40 excluding the vicinity of the in-vehicle end 41 and the vicinity of the out-vehicle end 42, are composed of a mounting base hard portion 50, an out-vehicle side wall hard portion 51, a seal portion hard portion 52, and a mounting base lip hard portion 53, which have a higher hardness than the above-mentioned parts and areas. Therefore, in this embodiment, the entire area of ​​the out-vehicle side wall 30 and the mounting base lip 27 is composed of a hard portion.

[0046] In this embodiment, the rigid part 50 of the mounting base, the rigid part 51 of the outer side wall, the rigid part 52 of the seal, and the rigid part 53 of the mounting base lip are made of PP (polypropylene), and the areas excluding the above-mentioned rigid parts are made of olefin-based thermoplastic elastomer (TPO) with an IRHD (International Rubber Hardness) of 80±5, and are manufactured by extrusion molding. Note that the rigid part 50 of the mounting base, the rigid part 51 of the outer side wall, the rigid part 52 of the seal, and the rigid part 53 of the mounting base lip may also be made of the same TPO as the other parts, in which case an IRHD of 100±5 is desirable. Furthermore, rigid resin materials other than PP, such as olefin-based resins such as polystyrene, may also be used.

[0047] When the weatherstrip 10 is assembled to the retainer 2, the in-vehicle projection 23 and the in-vehicle upper projection 24 of the mounting base 20 are housed in the in-vehicle groove 2a, and the out-vehicle portion 22 is housed in the out-vehicle groove 2b. In addition, the out-vehicle projection 25 and the out-vehicle upper projection 26 engage with the engaging portion 2c.

[0048] Furthermore, the outer side of the bulging portion 31 of the outer side wall 30 of the vehicle comes into contact with the inner side of the outer groove portion 2b of the retainer 2.

[0049] When the weatherstrip 10 is attached to the retainer 2, the hollow portion 43 of the sealing portion 40 is in a bulging shape downwards, and the sealing portion 40 and the mounting base lip 27 (hard portion 53 of the mounting base lip) are not in contact.

[0050] As the door glass 3 moves upward, the upper tip 3a of the door glass 3 comes into contact with the hard part 52 of the seal, and the hard part 52 of the seal deforms so that a recess is formed between it and the door glass 3, and moves upward so that the degree of deformation increases. Next, the hard portion 52 of the seal and the hard portion 53 of the mounting base lip come into contact, and while the contact between the hard portion 52 of the seal and the hard portion 53 of the mounting base lip is maintained, the hard portion 53 of the mounting base lip moves upward with the thin portion 28 of the lip as the pivot point, and finally the door glass 3 is closed.

[0051] As shown in Figure 2, the hard portion 52 of the seal is formed to cover a wide area, excluding the vicinity of the inner end 41 and outer end 42 of the seal 40, that is, an area wider than the thickness of the door glass 3. This is to ensure that the door glass 3 and the hard portion 52 of the seal are in reliable contact even if the contact position with the door glass 3 varies in the vehicle width direction.

[0052] Next, a second embodiment of the present invention will be described with reference to Figure 3. Figure 3 is a second embodiment of the present invention and is a cross-sectional view AA of Figure 1. However, this is a cross-sectional view when the weatherstrip 10 is assembled to a jig 60 whose inner surface shape is substantially the same as the peripheral edge 4 of the vehicle body opening, and the door glass 3 is in a fully closed state.

[0053] The weatherstrip 10 comprises a mounting base 20, an outer side wall 30, a sealing portion 40, a first inner side wall 70, a second inner side wall 71, and a second sealing portion 45.

[0054] The mounting base 20 abuts against the upper part 61 of the jig 60 and the outer part 62 of the jig 60. The inner upper projection 24 and the outer upper projection 26 abut against the upper part 61 of the jig, and the outer projection 25 abuts against the outer part 62 of the jig.

[0055] The outer side wall 30 of the vehicle is connected to the mounting base 20 and extends downward and outward from the vehicle. Furthermore, near the center of the outer side wall 30, a thin-walled portion 32 is provided on the inner side of the side wall to improve its ability to conform to the shape of the outer part 62 of the jig. Furthermore, below the thin-walled portion 32 of the side wall, there is a rigid outer side wall portion 51 that penetrates from the inside to the outside of the vehicle. In addition, the inner side of the rigid outer side wall portion 51 is provided with a rigid portion projection 54 that protrudes inward.

[0056] The inner end 41 of the seal portion 40 is connected to the inner side of the mounting base 20, and the outer end 42 is connected to the hard outer side wall portion 51, forming a hollow portion 43 that bulges downward. Furthermore, except for the area near the inner end 41 and the area near the outer end 42, the area that comes into contact with the upper tip 3a of the door glass 3 is provided with a hard sealing portion 52.

[0057] The first interior side wall 70 is formed by connecting to the mounting base 20 on the interior side of the vehicle from the connection point between the mounting base 20 and the sealing portion 40, and extending downward. It is also formed by bending inward slightly below the central portion.

[0058] The second sealing portion 45 is connected to the bent portion and the tip portion of the first inner side wall 70, is formed in the outward direction, and has a hollow portion 43. Furthermore, the second sealing portion 45 is equipped with a sealing portion bend 46.

[0059] The interior side of the first interior side wall 70 is provided with a second interior side wall 71 connected to the upper and lower ends of the first interior side wall 70, with a cavity between it and the first interior side wall 70. The interior side of the second interior side wall 71 is provided with an interior retaining lip 72 and an interior retaining rib 73.

[0060] Below the in-cabin retaining rib 73 of the second in-cabin side wall 71, it widens inward, and the lower end of the second in-cabin side wall 71 is provided with an in-cabin cover lip 74 that connects to the second seal portion 45.

[0061] The connection between the second inner side wall 71 and the second sealing portion 45 of the first inner side wall 70 is made of a harder material than the first inner side wall 70. This is to ensure a firm fixation to the jig 60 and to prevent it from coming off the jig 60 after assembly.

[0062] When the weatherstrip 10 is assembled to the jig 60, the upper projection 26 on the outside of the vehicle contacts the upper recess 65 of the jig, and the upper projection 24 on the inside of the vehicle contacts the upper edge 61 of the jig.

[0063] In the outer part 62 of the jig, the outer side wall 30 bends at the thin-walled portion 32 of the side wall, conforming to the shape of the inner side surface of the outer part 62 of the jig. In addition, the hard portion 51 of the outer side wall abuts against the inner surface of the outer part 62 of the jig.

[0064] In the interior portion 63 of the jig, the interior retaining lip 72 and interior retaining rib 73 of the second interior side wall 71 engage with the exterior projection 64 of the jig, and the interior cover lip 74 abuts against the interior lower edge portion 66 of the jig.

[0065] As the door glass 3 moves upward, the upper tip 3a of the door glass 3 comes into contact with the hard part 52 of the seal, and the hard part 52 deforms so that a recess is formed between it and the door glass 3, and moves upward so that the degree of deformation increases. Furthermore, as the depth of the recess increases, it also comes into contact with the outer surface 3b of the door glass 3. Furthermore, the lower side of the bent portion 46 of the second seal portion 45 comes into contact with the interior side surface 3c of the door glass 3, causing the bent portion 46 of the seal portion to move upward.

[0066] Finally, the hard part 52 of the sealing section and the hard part projection 54 come into contact, and the door glass 3 is closed.

[0067] Next, a third embodiment of the present invention will be described with reference to Figure 4. Figure 4 is a third embodiment of the present invention and is a cross-sectional view of BB in Figure 1. Figure 4 shows the pillar side of the peripheral edge 4 of the vehicle body opening, and in the weatherstrip 10, it corresponds to the rear vertical edge of the door glass 3. Also, Figure 4 shows the state in which the door glass 3 and the weatherstrip 10 are in contact.

[0068] The peripheral edge of the vehicle body opening is equipped with a B-pillar 80 and a flange 5. The flange 5 is made of steel. The flange 5 is located on the interior side of the B-pillar 80, and from the front of the vehicle body, the first flat section 5a, the second flat section 5b, and the third flat section 5c are connected by the first stepped section 5d and the second stepped section 5e. The second flat section 5b is located further outward than the first flat section 5a, and the third flat section 5c is located further outward than the second flat section 5b. A second weatherstrip 11 is attached to the first flat portion 5a of the flange 5. A detailed explanation of the second weatherstrip 11 is omitted, but it includes a second sealing portion 45, which contacts the interior side surface 3c of the door glass 3.

[0069] The B-pillar 80 comprises an outer B-pillar portion 81 and an inner B-pillar portion 82. The inner B-pillar portion 82 is connected to the inner surface of the outer B-pillar portion 81, and its tip extends away from the inner B-pillar portion 82. Furthermore, the outer side of the B-pillar near the center of the inner portion 82 is provided with an inner step portion 83. Furthermore, the outer portion 81 and inner portion 82 of the B-pillar are provided with opposing outer hook portions 84 and inner hook portions 85.

[0070] The weatherstrip 10 comprises a mounting base 20, an outer side wall 30, an inner side wall 75, a lip-shaped outer sealing portion 47, and a lip-shaped inner sealing portion 48. Furthermore, the connecting portion between the outer side wall 30 and the outer sealing portion 47 is provided with a thin-walled outer connecting recess 33, and the connecting portion between the inner side wall 75 and the inner sealing portion 48 is provided with a thin-walled inner connecting recess 34. In this third embodiment, the outer sealing portion 47 is the sealing portion 40.

[0071] The exterior sealing portion 47 is formed by extending from the exterior connecting recess 33 toward the interior of the vehicle and away from the mounting base 20 in a convex shape, with its tip portion extending in a convex and arc-shaped curve toward the mounting base 20. On the other hand, the interior sealing portion 48 extends from the connection point with the interior side wall 75 toward the exterior and toward the mounting base 20, and is formed to extend slightly convex and curved toward the interior side wall 75.

[0072] The mounting base 20 includes a mounting base projection 29 that extends outward from the rear of the vehicle body. The outer surface of the mounting base projection 29 is provided with two outer projections 25. Furthermore, the interior side of the mounting base projection 29 is provided with two first mounting base lips 27a and a second mounting base lip 27b.

[0073] The mounting base 20, excluding the connection portion with the outer side wall 30, the first mounting base lip 27a and the second mounting base lip 27b, the outer side wall 30, the vicinity of the outer connecting recess 33 in the outer sealing portion 47, and the vicinity of the connection portion between the inner sealing portion 48 and the inner sealing portion 48 of the inner side wall 75, are composed of a mounting base hard portion 50, a sealing portion hard portion 52, and an inner side wall hard portion 55, which have higher hardness than the above-mentioned portions. Furthermore, the rigid portion 55 of the inner side wall of the vehicle is provided with a rigid portion projection 54 that partially protrudes inward.

[0074] The weatherstrip 10 is attached to the B-pillar 80 by inserting the mounting base projection 29 between the B-pillar's outer side portion 81 and the B-pillar's inner side portion 82. At this time, the mounting base 20's connection portion with the outer side wall 30 abuts against the outer hook portion 84, and the mounting base's rigid portion 50 abuts against the inner hook portion 85. Furthermore, the exterior projection 25 abuts against the interior side surface of the exterior portion 81 of the B-pillar. Also, on the exterior side surface of the interior portion 82 of the B-pillar, the second mounting base lip 27b abuts against the rear side of the interior step portion 83, and the first mounting base lip 27a abuts against the front side of the interior step portion 83. As a result, it is possible to prevent the mounting base projection 29 from coming off the exterior portion 81 and the interior portion 82 of the B-pillar 80. Furthermore, the hard portion projection 54 abuts against the second flat portion 5b of the flange 5.

[0075] When the weatherstrip 10 comes into contact with the door glass 3, the rear end 3d of the door glass 3 comes into contact with the hard part 52 of the outer seal part 47 and pushes the hard part 52 toward the rear of the vehicle body, causing the front end 44 of the seal part (hard part 52) ​​to come into contact with the hard part 50 of the mounting base.

[0076] On the other hand, the tip of the interior sealing portion 48 abuts against the interior side surface 3c of the door glass 3.

[0077] Next, a fourth embodiment of the present invention will be described with reference to Figure 5. Figure 5 is a fourth embodiment of the present invention and is a cross-sectional view of BB in Figure 1. Figure 5 shows the pillar side of the peripheral edge 4 of the vehicle body opening, and in the weatherstrip 10, it corresponds to the rear vertical edge of the door glass 3. Also, Figure 5 shows the state in which the door glass 3 and the weatherstrip 10 are in contact. Note that this fourth embodiment is a modification of the third embodiment described above.

[0078] The differences between this fourth embodiment and the third embodiment described above are: firstly, in this fourth embodiment, the hard seal portion 52 is not formed on the outer seal portion 47; secondly, the outer seal portion 47 is formed to be shorter; thirdly, the hard seal portion 52 is formed on the inner seal portion 48, and the hard seal portion 52 is formed in the area excluding the connection portion between the inner side wall 75 and the inner seal portion 48, that is, in the area outside the vehicle from the inner connecting recess 34; and fourthly, the inner seal portion 48 is convex and arc-shaped, extending outward from the connection portion with the inner side wall 75 and toward the mounting base 20, and then curving toward the inner side wall 75. Therefore, in this fourth embodiment, the inner seal portion 48 is the seal portion 40.

[0079] When the weatherstrip 10 comes into contact with the door glass 3, the rear end 3d of the door glass 3 comes into contact with the exterior sealing portion 47 and pushes the exterior sealing portion 47 toward the rear of the vehicle body. At this time, the exterior sealing portion 47 does not come into contact with the mounting base rigid portion 50.

[0080] On the other hand, on the interior side, the hard portion 52 of the sealing part comes into contact with the interior side surface 3c of the door glass 3, and the tip portion 44 (hard portion 52) of the sealing part comes into contact with the interior side wall hard portion 55.

[0081] Next, a fifth embodiment of the present invention will be described with reference to Figure 6. Figure 6 is a fifth embodiment of the present invention and is a cross-sectional view of BB in Figure 1. Figure 6 shows the pillar side of the peripheral edge 4 of the vehicle body opening, and in the weatherstrip 10, it corresponds to the rear vertical edge of the door glass 3. Also, Figure 6 shows the state in which the door glass 3 and the weatherstrip 10 are in contact.

[0082] In this fifth embodiment, the weatherstrip 10 is attached to the flange 5. The peripheral edge of the vehicle body opening is provided with a B-pillar 80 and a flange 5. The flange 5 is located on the interior side of the B-pillar 80, and from the front side of the vehicle body, a first flat portion 5a and a second flat portion 5b are connected by a first stepped portion 5d. The second flat portion 5b is located on the exterior side of the vehicle than the first flat portion 5a.

[0083] The weatherstrip 10 comprises a mounting base 20, a first inner side wall 70, a second inner side wall 71, a sealing portion 40, a second sealing portion 45, and a mounting base lip 27.

[0084] The mounting base 20 is connected to the sealing portion 40 at one end, to the second interior side wall 71 at the other end, and to the first interior side wall 70 in the middle. In the mounting base 20, the connection portion between the first inner side wall 70 and the seal portion 40 is provided with a thickened portion 90 and a thickness-inclined portion 91 in which the thickness decreases in the direction of the connection portion with the seal portion 40. The connection portion between the first inner side wall 70 and the second inner side wall 71 is provided with a thinned portion 92 in which the thickness is thinner than the thickened portion 90 and the film thickness is substantially uniform in the direction of the connection portion with the second inner side wall 71. The thickened portion 90 is also provided with a mounting base recess 93. Furthermore, a pillar-side lip 94 is provided from the side of the connection portion with the seal portion 40.

[0085] The mounting base 20 is provided with a mounting base lip 27 that extends toward the sealing portion 40. The mounting base lip 27 is curved convexly toward the sealing portion 40. In addition, the mounting base 20 side near the base of the mounting base lip 27 is provided with a thin-walled lip thin-walled portion 28.

[0086] The first interior side wall 70 and the second interior side wall 71 are connected to the mounting base 20, connected at the front of the vehicle body, and have a side wall connecting portion 76, and have an A-shape. Furthermore, the inner side of the second inner side wall 71 is provided with two inner side retaining ribs 73, flanking the side wall connecting portion 76. Furthermore, an interior cover lip 74 is provided extending inward from the tip of the second interior side wall 71. The interior cover lip 74 abuts against an interior member 6 disposed on the interior side of the second interior side wall 71.

[0087] The sealing portion 40 is located on the outer side of the first inner side wall 70 and connects to the front side of the vehicle body of the side wall connecting portion 76, and is formed in an arc shape that bulges away from the mounting base 20 and the first inner side wall 70. Furthermore, the second sealing portion 45 is formed extending from the tip of the first inward side wall 70 toward the outward side and toward the mounting base 20.

[0088] The weatherstrip 10 is attached to the first stepped portion 5d of the flange 5 with double-sided tape 7. At this time, the interior retaining rib 73 comes into contact with the first flat portion 5a of the flange 5. Furthermore, when the B-pillar 80 is installed, the pillar-side lip 94 deforms, and the tip of the B-pillar 80 and the interior side of the vehicle come into contact with the pillar-side lip 94.

[0089] The first interior side wall 70, the second interior side wall 71, the side wall connecting portion 76, the interior retaining rib 73, the interior cover lip 74, the pillar side lip 94, the second seal portion 45, and the area excluding the connecting portion with the seal portion 40 of the mounting base 20 and the portion of the seal portion 40 that does not come into contact with the door glass 3 are composed of a mounting base hard portion 50, a mounting base lip hard portion 53, and a seal portion hard portion 52, which have a higher hardness than the above-mentioned parts and areas. Therefore, in this fifth embodiment, the entire area of ​​the mounting base lip 27 is formed of a hard portion.

[0090] When the weatherstrip 10 comes into contact with the door glass 3, the rear end 3d of the door glass 3 and the interior side surface 3c of the door glass come into contact with the hard seal portion 52 of the seal portion 40. At the same time, the hard seal portion 52 deforms so as to form a recess between itself and the door glass 3, and the hard seal portion 52 comes into contact with the hard lip portion 53 of the mounting base.

[0091] Next, a sixth embodiment of the present invention will be described with reference to Figure 7. Figure 7 is a sixth embodiment of the present invention and is a cross-sectional view of Figure 1, AA. However, this is a cross-sectional view when the weatherstrip 10 is assembled to a jig 60 whose inner surface shape is substantially the same as the peripheral edge 4 of the vehicle body opening, and the door glass 3 is in a fully closed state. This sixth embodiment is a modified version of the second embodiment described above. In this sixth embodiment, the seal portion 40 is the second seal portion 45.

[0092] The weatherstrip 10 comprises a mounting base 20, an outer side wall 30, a first sealing portion 49, a first inner side wall 70, a second inner side wall 71, and a second sealing portion 45 (sealing portion 40).

[0093] The differences between this sixth embodiment and the second embodiment described above are: firstly, in this sixth embodiment, the outer side wall 30 does not have an outer side wall hard portion 51 and a hard portion projection 54, and the area where the outer side wall hard portion 51 was formed in the second embodiment bulges inward; secondly, the first seal portion 49 does not have a seal portion hard portion 52; thirdly, the upper end of the hard second inner side wall 71 extends to the connection portion between the first inner side wall 70 and the mounting base 20; fourthly, the extended hard second inner side wall 71 is connected to a lower, outer, and convex arc-shaped lip hard portion 56 on the outer side; and fifthly, the inner retaining lip 72 is formed to be large, and when the weatherstrip 10 is assembled to the jig 60, the inner retaining lip 72 abuts against the jig inner portion 63. The extended rigid second inner side wall 71 connected to the lip rigid section 56 is referred to as the base rigid section 58. The hardness of the base rigid section 58 (second inner side wall 71) is the same as that of the lip rigid section 56.

[0094] In the second seal portion 45, the portion that contacts the lip hard portion 56 of the bent portion 46 of the seal portion has an acute-angled tip and is formed in a thick, solid shape.

[0095] Furthermore, a thin-walled portion 57 of the lip rigid portion is formed on the interior side of the base of the lip rigid portion 56.

[0096] As the door glass 3 moves upward, the lower side of the bent portion 46 of the second seal portion 45 comes into contact with the interior surface 3c of the door glass 3, causing the bent portion 46 to move upward.

[0097] Furthermore, the upper tip 3a of the door glass 3 comes into contact with the first sealing portion 49, and the first sealing portion 49 deforms so that a recess is formed between it and the door glass 3, and moves upward so that the degree of deformation increases.

[0098] Furthermore, the interior side of the bent portion 46 of the seal comes into contact with the rigid lip portion 56, and the rigid lip portion 56 deforms while in contact with the bent portion 46 due to the thin-walled portion 57 of the rigid lip portion.

[0099] Finally, the door glass 3 is closed with the interior side of the bent seal portion 46 in contact with the hard lip portion 56.

[0100] As described in detail above, the embodiments of the present invention provide the following effects. (1) In the first and fifth embodiments described above, the weatherstrip 10 comprises a mounting base 20 attached to the periphery 4 of the vehicle body opening and a sealing portion 40 that abuts against the door glass 3. The sealing portion 40 is hollow and includes a hard sealing portion 52. Since the door glass 3 abuts against the hard sealing portion 52, the sealing portion 40 flexes and deforms, sealing the space between the periphery 4 of the vehicle body opening and the door glass 3. The hard sealing portion 52 also increases the rigidity of the weatherstrip 10, and by utilizing impedance matching with the door glass 3, the vibration energy of the door glass 3 can be efficiently transmitted to the hard sealing portion 52. As a result, even in automobiles with frameless doors, the vibration of the door glass 3 can be reduced by the weatherstrip 10.

[0101] (2) The mounting base 20 also includes a mounting base rigid portion 50 and a mounting base lip 27 connected to the mounting base rigid portion 50 and protruding inward from the hollow portion 43. The mounting base lip 27 includes a mounting base lip rigid portion 53, and the seal portion rigid portion 52 is in contact with the mounting base lip rigid portion 53. By utilizing impedance matching with the door glass 3, the vibration energy of the door glass 3 propagated to the seal portion rigid portion 52 can be dissipated to the mounting base rigid portion 50 via the mounting base lip rigid portion 53. As a result, even in a vehicle body with sashless doors, the vibration of the door glass 3 can be further reduced by utilizing impedance matching that brings the impedance of the weatherstrip 10 closer to the impedance of the glass.

[0102] (3) In addition, in the first embodiment, the rigid part 50 of the mounting base abuts against the retainer 2 at the upper projection 26 on the outside of the vehicle, and the rigid part 51 on the outside of the vehicle wall abuts against the retainer 2 at the groove 2b on the outside of the vehicle. In the fifth embodiment, the rigid part 50 of the mounting base abuts against the flange 5. As a result, the vibration energy of the door glass 3 transmitted to the rigid part 50 of the mounting base can be dissipated to the vehicle body side via the retainer 2 and flange 5. As a result, even in a vehicle body with a frameless door type, the vibration of the door glass 3 can be further reduced by utilizing impedance matching, which brings the impedance of the weatherstrip 10 closer to the impedance of the glass.

[0103] (4) In the second embodiment described above, the seal portion 40 is hollow, and an outer side wall 30 is provided between the mounting base 20 and the seal portion 40. The outer side wall 30 has an outer side wall hard portion 51 that penetrates from the inside to the outside of the vehicle, and the outer side wall hard portion 51 has a hard portion projection 54 that protrudes inward. Since the seal portion hard portion 52 abuts against the hard portion projection 54, in addition to the effects of (1) described above, the vibration energy of the door glass 3 transmitted to the seal portion hard portion 52 can be dissipated to the outer side wall hard portion 51 via the hard portion projection 54 by utilizing impedance matching with the door glass 3. As a result, even in a vehicle body with sashless doors, the vibration of the door glass 3 can be further reduced by utilizing impedance matching that brings the impedance of the weatherstrip 10 closer to the impedance of the glass.

[0104] (5) Furthermore, since the rigid outer side wall portion 51 is formed to penetrate from the inside to the outside of the vehicle, the outer side of the rigid outer side wall portion 51 can be dissipated to the jig 60 (to the vehicle body side via the retainer 2 in Embodiment 1 in the case of an automobile). As a result, even in a vehicle body with a frameless door type, vibration of the door glass 3 can be further reduced by utilizing impedance matching, which brings the impedance on the weatherstrip 10 side closer to the impedance of the glass.

[0105] (6) In the third and fourth embodiments described above, the seal portion 40 is lip-shaped, and in the third embodiment, the hard portion 52 of the seal portion is formed on the exterior seal portion 47, and in the fourth embodiment, the hard portion 52 of the seal portion is formed on the interior seal portion 48, and deforms to come into contact with the door glass 3, so that the vibration energy of the door glass 3 can be efficiently transmitted to the hard portion 52 of the seal portion by utilizing impedance matching with the door glass 3. As a result, even in automobiles with frameless doors, the vibration of the door glass 3 can be reduced by the weatherstrip 10.

[0106] (7) In the third embodiment, the hard portion 52 of the seal is in contact with the hard portion 50 of the mounting base, and in the fourth embodiment, the hard portion 52 of the seal is in contact with the hard portion 55 of the inner side wall of the vehicle, so that the vibration energy of the door glass 3 transmitted to the hard portion 52 of the seal can be dissipated to the hard portion 50 of the mounting base or the hard portion 55 of the inner side wall of the vehicle. As a result, even in a vehicle body with sashless doors, the vibration of the door glass 3 can be further reduced by using impedance matching, which brings the impedance of the weatherstrip 10 closer to the impedance of the glass.

[0107] (8) In the third embodiment, the mounting base rigid portion 50 is connected to the vehicle-side side wall rigid portion 55, and a rigid portion projection 54 is formed on the vehicle-side side wall rigid portion 55, and the rigid portion projection 54 is in contact with the flange 5, so that the vibration energy of the door glass 3 transmitted to the mounting base rigid portion 50 can be dissipated to the flange 5, i.e., to the vehicle body side, via the vehicle-side side wall rigid portion 55. As a result, even in a vehicle body with a sashless door type, the vibration of the door glass 3 can be further reduced by utilizing impedance matching, which brings the impedance of the weatherstrip 10 closer to the impedance of the glass.

[0108] (9) On the other hand, in the fourth embodiment, a hard portion projection 54 is formed on the hard portion 55 of the inner side wall of the vehicle and is in contact with the flange 5, so that the vibration energy of the door glass 3 transmitted to the hard portion 55 of the inner side wall of the vehicle can be dissipated to the flange 5, i.e., to the vehicle body side. As a result, even in a vehicle body with a frameless door type, the vibration of the door glass 3 can be further reduced by utilizing impedance matching, which brings the impedance on the weatherstrip 10 side closer to the impedance of the glass.

[0109] (10) In the sixth embodiment described above, the second seal portion 45, which is the seal portion 40, is hollow and has a seal portion bend portion 46. The seal portion bend portion 46 causes a part of the seal portion 40 to become a solid shape, increasing its rigidity. When the more rigid seal portion 40 (seal portion bend portion 46) comes into contact with the door glass 3, the vibration energy of the door glass 3 can be efficiently transmitted to the seal portion bend portion 46 by utilizing impedance matching. In addition, since the seal portion bend portion 46 comes into contact with the lip rigid portion 56, the vibration energy transmitted to the seal portion bend portion 46 can be transmitted to the lip rigid portion 56. As a result, in a car with a frameless door, the vibration of the door glass 3 can be reduced by the weatherstrip 10.

[0110] (11) Furthermore, since the lip rigid portion 56 is formed in connection with the base rigid portion 58, the vibration energy transmitted to the lip rigid portion 56 can be dissipated to the base rigid portion 58.

[0111] (12) Furthermore, since the base-side rigid portion 58 is in contact with the jig-side vehicle-inside portion 63 of the jig 60, the vibration energy transmitted to the lip rigid portion 56 can be more efficiently dissipated via the base-side rigid portion 58 to the jig 60 side, that is, from the vehicle-side holding lip 72 to the jig-side vehicle-inside portion 63 (vehicle body opening peripheral edge 4 side).

[0112] 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.

[0113] For example, in the first embodiment described above, the entire area of ​​the outer side wall 30 and the mounting base lip 27 is made of a rigid portion. However, for the outer side wall 30, a rigid outer side wall portion 51 may be formed on a part of the outer side wall 30, as long as vibration energy from the door glass 3 can be transmitted from the rigid mounting base portion 50 to the outer groove portion 2b of the retainer 2. Similarly, for the mounting base lip 27, a rigid mounting base lip portion 53 may be formed on a part of the mounting base lip 27, as long as it contacts the rigid sealing portion 52 and the rigid mounting base portion 50, and vibration energy from the door glass 3 can be transmitted from the rigid sealing portion 52 to the rigid mounting base portion 50.

[0114] For example, in the fourth embodiment described above, a rigid mounting base portion 50 is formed on the mounting base portion 20, but it is not necessary to form a rigid mounting base portion 50 on the mounting base portion 20.

[0115] For example, in the sixth embodiment described above, the entire second inner side wall 71 is made into a base-side hard portion 58 and its hardness is the same as that of the lip hard portion 56. However, the portion connected to the lip hard portion 56 and leading to the jig inner portion 63 may be formed from a material with the same hardness as the lip hard portion 56 as an energy dissipation route, and the portion assembled to the jig 60 may be formed from a material with a different hardness, with a hardness appropriate from the viewpoint of preventing it from coming off the jig 60 after assembly.

[0116] For example, in the sixth embodiment described above, the second in-vehicle side wall 71 is made into a base-side rigid portion 58, but the base-side rigid portion 58 may be formed within the mounting base 20. [Explanation of symbols]
