Description

Weatherstrip for Automobile

[0001] The present invention relates to a weatherstrip for an automobile that is attached to the periphery of a door opening on the vehicle body side and elastically contacts the periphery of the door to seal the inside and outside of the vehicle cabin.

[0002] As a conventional weatherstrip for an automobile in this type of door opening (hereinafter simply referred to as a weatherstrip), the one described in Patent Document 1 below is known.

[0003] FIG. 1 is a perspective view of an automobile to which the weatherstrip of the present invention and a conventional weatherstrip for an automobile are applied, FIG. 8 is a cross-sectional view taken along line A - A of FIG. 1 showing the conventional weatherstrip for an automobile in the door open state, and FIG. 9 is a cross-sectional view taken along line A - A of FIG. 1 showing the conventional weatherstrip for an automobile when the door is closed.

[0004] The conventional weatherstrip 1 described in this publication is attached to a flange portion 05 formed by overlapping two metal panels 04a and 04b formed along the periphery of a door opening 03 of, for example, a front door 02 of a vehicle body of an automobile 01, as shown in FIGS. 1 and 8. A weatherstrip 1' having the same structure is also provided at the periphery of the door opening 03' of the rear door 02'.

[0005] As shown in FIGS. 8 and 9, this weatherstrip 1 includes a mounting base 2 which is a U-shaped welt portion having an insertion and fitting portion at the tip of the flange portion 05 and having an inner side wall 3 inside the vehicle, an outer side wall 4 outside the vehicle, and a connecting wall 5 connecting both side walls 3 and 4; a hollow seal portion 6 made of sponge rubber material provided integrally on the outer surface of the outer side wall 4 of the mounting base 2, which elastically contacts a door panel 06 at the periphery of the front door 02 when the front door 02 is closed; and a cloth member 7 covering the outer surface of the mounting base 2 and colored the same color as the interior color inside the vehicle.

[0006] The mounting base 2 is integrally provided with two holding lips 3a and 4a that contact both the inner and outer surfaces of the flange portion 05 on the inner surfaces of the inner side wall 3 inside the vehicle and the outer side wall 4 outside the vehicle, and the flange portion 05 is held in a sandwiched state by these respective holding lips 3a and 4a.

[0007] The hollow seal portion 6 is formed in a substantially semicircular cross-section, with one end 6a connected to the outer surface of the outer side wall 4 near the connecting wall 5, while the other end 6b connected to the outer surface of the outer side wall 4 near the opening of the mounting base 2. Furthermore, as shown in Figure 9, when the front door 02 is closed, the hollow seal portion 6 compresses and deforms under the pressing force of the door panel 06, elastically contacting and sealing the space between the door opening 03 and the door panel 06.

[0008] The fabric member 7 has one side portion 7a in the width direction that extends to the vicinity of one end portion 6a of the hollow seal portion 6 of the outer side wall 4, while the other side portion 7b in the width direction extends to the end near the opening of the inner side wall 3.

[0009] Furthermore, a lip portion 8 is provided at one end 6a of the hollow seal portion 6, covering one side 7a of the fabric member 7. This lip portion 8 is made of sponge rubber material, just like the hollow seal portion 6, and extends from the base end 8a on the end 6a side of the hollow seal portion 6 toward the connecting wall 5, with the lower surface of the tip portion 8b in contact with the outer surface of one side 7a of the fabric member 7. In this way, by covering one side 7a of the fabric member 7 with the lip portion 8, peeling of the one side 7a is prevented and the appearance is improved.

[0010] Japanese Patent Publication No. 7-96801 (see Figure 1)

[0011] However, in the conventional automotive weatherstrip described above, as mentioned earlier, the lip portion 8 is formed of a soft sponge rubber material, and the lower surface of the tip portion 8b simply abuts against the upper surface of one side portion 7a of the fabric member 7. Therefore, as shown in Figure 9, when the hollow seal portion 6 is pressed against the door panel 06 and compressed when the front door 02 is closed, the lip portion 8 is prone to displacement of the tip portion 8b in the vertical direction in the figure due to this compression deformation, which can impair the continuity of the fabric member 7. In addition, the lip portion 8 may bend outward (in the direction of the white arrow in Figure 9) with the base end portion 8a as a fulcrum due to the compression deformation of the hollow seal portion 6, causing the lip portion 8 to open. This can create a gap S between the lower surface of the tip portion 8b and the outer surface of one side portion 7a of the fabric member 7, making it easier for dirt and other debris to enter the interior through this gap S, and potentially exposing one side portion 7a of the fabric member 7, resulting in a poor appearance and a decrease in overall appearance quality.

[0012] The present invention was devised in view of the technical problems of the conventional automotive weatherstrips, and aims to provide an automotive weatherstrip that can maintain a stable and reliable pressing state against one side of the fabric member at the tip of the protrusion, even if the hollow seal portion is compressed and deformed when the door is closed, because the tip of the rigid protrusion presses against one side of the fabric member from a nearly vertical direction in a line contact state.

[0013] The invention described in claim 1 of this application is an automotive weatherstrip comprising: a mounting base having a U-shaped cross-section that is attached to a flange portion formed along the door opening edge of a vehicle body; a hollow sealing portion whose both ends are integrally bonded to the outer surface of the mounting base and which elastically contacts the door panel when the door is closed; and a fabric member that covers at least the outer surface of the mounting base and whose one side in the width direction is positioned near the portion of the mounting base to which one end of the hollow sealing portion is bonded, wherein a projection is provided on the outer surface of one end of the hollow sealing portion that presses against the outer surface of one side of the fabric member in a line contact state, and the one end of the hollow sealing portion and the projection are formed from a solid material of rubber or synthetic resin.

[0014] According to the invention described in claim 1 of this application, even if the hollow seal portion is compressed and deformed when the door is closed, the tip of the projection can maintain a stable and reliable pressing state against one side of the fabric member. As a result, misalignment of the projection and opening of the door are suppressed, preventing the entry of dirt and other debris, and improving the appearance and overall quality.

[0015] This is a perspective view of an automobile to which the present invention and conventional automotive weatherstrips are applied.

This is a cross-sectional view taken along line A-A in Figure 1, showing a conventional automotive weatherstrip with the door open. This is a cross-sectional view taken along line A-A in Figure 1, showing a conventional automotive weatherstrip with the door closed.

[0016] Hereinafter, embodiments of the automotive weatherstrip according to the present invention will be described with reference to the drawings. This weatherstrip is applied to the periphery of the door openings of the front and rear doors of a vehicle body, just like the conventional one described above. However, for the sake of explanation, the following description will focus on the weatherstrip attached to the periphery of the door opening 03 of the front door 02.

[0017] Figure 2 is a cross-sectional view taken along line A-A in Figure 1, showing an embodiment of the automotive weatherstrip according to the present invention with the door in the open position; Figure 3 is a cross-sectional view taken along line A-A in Figure 1, showing the automotive weatherstrip of this embodiment with the door closed; and Figure 4 is an enlarged view of section B in Figure 2.

[0018] As described above, the weatherstrip 21 is attached to a flange portion 05 formed along the periphery of the door opening 03 of the front door 02 of the automobile 01 shown in Figure 1. This flange portion 05 is formed by overlapping, for example, three metal panels 04a to 04c and joining them intermittently in the longitudinal direction by spot welding or the like. The weatherstrip 21 of this embodiment, as shown in Figures 2 and 3, has an inverted U-shaped mounting base portion 22 that fits into the flange portion 05 and has an inner side wall 23, an outer side wall 24 and a connecting wall 25 that connects these two side walls 23 and 24, and a hollow sealing portion 26 integrally provided on the outer surface of the outer side wall 24 of the mounting base portion 22, which elastically contacts, for example, a door panel 06 provided on the periphery of the front door 02 when the front door 02 is closed.

[0019] The mounting base 22 is integrally molded from a solid material, such as hard rubber or hard resin, to ensure rigidity, and has a metal core material 22a with a U-shaped cross-section embedded inside. The mounting base 22 has two upper and lower retaining lips 4aa and 4ab projecting toward the outer side wall 24 from the inner surface of the inner side wall retaining lip 4a, and three protruding parts 24a to 24c are integrally provided on the inner surface of the outer side wall 24, projecting toward the inner side wall 23. In addition, the lowest part of the outer side wall 24 in Figure 2 has an integral retaining lip 24d made of sponge rubber material, the tip of which extends toward the inner side wall 23.

[0020] Therefore, when the mounting base 22 is fitted onto the flange portion 05, the tips of the respective retaining lips 23a and 23b, the protruding portions 24a to 24c, and the tip of the retaining lip 24d elastically contact the inner and outer sides of the flange portion 05 in a clamping manner, thereby holding the mounting base 22 to the flange portion 05.

[0021] Furthermore, a cover lip 27 extending toward the interior is integrally provided at the end of the connecting wall 25 of the mounting base 22 on the side facing the interior side wall 23. This cover lip 27, like the connecting wall 25, is made of a solid material and covers the leading edge of interior materials 28 such as door trims and garnishes that extend from the interior side toward the interior side wall 23.

[0022] As shown in Figure 2, the hollow seal portion 26 is basically integrally formed from sponge material and is tapered from both ends 26a and 26b, which are joined to the outer surface of the outer side wall 24 of the vehicle, to the tip 26c. One end 26a of the hollow seal portion 26 is joined to the vicinity of the connecting wall 25 of the outer side wall 24 of the vehicle, while the other end 26b is joined to the vicinity of the lower end of the outer side wall 24 in Figure 2.

[0023] The hollow seal portion 26 has a connecting portion 26d that is connected to the end of a projection 35, which will be described later, provided on the one end 26a side. This connecting portion 26d is made of sponge rubber material, just like the main body of the hollow seal portion 26, and is formed in a curved shape so as to bulge upward in the figure above the projection 35 when in the free state shown in Figure 2. Then, as shown in Figure 3, when the front door 02 is closed and the hollow seal portion 26 is compressed and deformed, the connecting portion 26d bends and deforms in the direction of bending, and this elastic reaction force presses the projection 35, which will be described later, toward one side 34a of the fabric member 34.

[0024] Furthermore, a linear support wall 31 is provided inside the hollow seal portion 26, dividing it into an interior seal portion 29 at both ends 26a and 26b and an exterior seal portion 30 at the front end 26c. This support wall 31 is made of sponge rubber material, just like the main body of the hollow seal portion 26, and in the free state when the front door 02 is open, as shown in Figure 2, it is formed as a linear, elongated plate that crosses the interior at the central position inside the hollow seal portion 26, and extends along the longitudinal direction of the weatherstrip 21. The support wall 31 is positioned to divide the hollow seal portion 26 from approximately the center inside to the interior seal portion 29 at both ends 26a and 26b, and the exterior seal portion 30 at the front end 26c, where the door panel 06 elastically contacts when the front door 02 is closed.

[0025] Furthermore, a first projection 32 is integrally provided on the outer surface of the hollow seal portion 26 at the location where one end of the support wall 31 in the width direction is joined, and a second projection 33 is integrally provided on the same plane as the first projection 32 and on the tip portion 26c side. These first and second projections 32 and 33 are formed in a substantially triangular shape in cross-section from the same sponge rubber material as the hollow seal portion 26, and extend parallel to the longitudinal direction of the hollow seal portion 26, with their respective apex points set to the same height.

[0026] As shown in Figure 3, when the front door 02 is closed, the hollow seal portion 26 elastically contacts the outer surface of the outer seal portion 30 on the tip portion 26c side of the door panel 06, causing the outer seal portion 30 to compress and deform (collapse). At the same time, the first projection 32 and the second projection 33 elastically contact the outer surface of the door panel 06, creating a double seal.

[0027] Furthermore, as shown in Figures 2 and 3, a fabric member 34 is provided to cover the outer surface of the connecting wall 25 of the mounting base 22 and the outer surface of the tip portion 27a of the cover lip 27. This fabric member 34 is continuously arranged along the longitudinal direction of the weatherstrip 21 and is bonded and fixed to the outer surfaces of the connecting wall 25 and the cover lip 27 with impregnated adhesive. This fabric member 34 is colored the same as the interior material 28, and one side portion 34a in the width direction extends to near the connecting end of the connecting wall 25 with the vehicle-side side wall 24, while the other side portion 34b extends to a position where it is wrapped around the inner surface of the tip portion 27a of the cover lip 27.

[0028] As shown in Figures 2 to 4, the hollow seal portion 26 has a projection 35 integrally provided on the outer surface of one end 26a that presses against the outer surface of one side 34a of the fabric member 34. This projection 35 is formed in a substantially triangular shape in cross-section, and its tip 35a, which is the apex, presses against the outer surface of one side 34a of the fabric member 34 from a substantially vertical direction. This projection 35 and the one end 26a of the hollow seal portion 26 are formed of a solid material, just like the outer side wall 24 of the vehicle, and have higher rigidity than the main body of the hollow seal portion 26, which is made of sponge rubber material.

[0029] Furthermore, as shown in Figure 4, the projection 35 has a relatively large thickness W from the inner surface of the hollow seal portion 26 to the tip portion 35a, and in combination with the solid material, high rigidity is ensured. In addition, the joint base portion 26a of one end of the hollow seal portion 26 with the outer side wall 24 is formed with a thicker wall, and this portion also has high rigidity.

[0030] Between the projection 35 and one end portion 26a, a pressure-applying portion 36 is provided to apply a pressing force to the projection 35 toward the upper surface of one side portion 34a of the fabric member 34. That is, as shown in Figure 4, this pressure-applying portion 36 is formed to be thinner than the projection 35 and one end portion 26a of the hollow seal portion 26, and is bent in a curved shape to apply a pressing force to the projection 35 toward the outer surface of one side portion 34a of the fabric member 34.

[0031] Figure 5 is an enlarged cross-sectional view of a key part showing the state in which adhesive has been applied to one side of the fabric member of the automotive weatherstrip of this embodiment.

[0032] Furthermore, a space 37 is formed inside the protrusion 35, which includes the pressure-applying portion 36, and one end portion 26a. This space 37 accommodates one side portion 34a of the fabric member 34.

[0033] Furthermore, this space 37 is designed to conceal any excess adhesive 38 when, for example, an adhesive 38 for preventing curling is applied to the edge of one side portion 34a of the fabric member 34, as shown in Figure 5. [Effects of the weatherstrip according to this embodiment] The effects of the weatherstrip 21 according to this embodiment will now be described.

[0034] In this embodiment, the weatherstrip 21, when the front door 02 is open as shown in Figure 2, has a free state of the hollow seal portion 26. When the front door 02 is closed as shown in Figure 3, the door panel 06 elastically contacts the exterior seal portion 30 of the hollow seal portion 26, causing compression deformation (crushing deformation), and the first and second protrusions 32 and 33 elastically contact the outer surface of the door panel 06. This double seal of the first and second protrusions 32 and 33 improves the sealing performance of the hollow seal portion 26.

[0035] Furthermore, when the hollow seal portion 26 is compressed and deformed when the front door 02 is closed, as shown in Figure 3, the projection 35 is pressed via the elastic reaction force of the curved joint portion 26d, and the tip portion 35a presses against the outer surface of one side portion 34a of the fabric member 34 in a nearly vertical line contact state. As a result, the projection 35 can stably and reliably press against the outer surface of one side portion 34a of the fabric member 34 with its tip portion 35a without causing vertical displacement or gaps due to opening.

[0036] Furthermore, since one end 26a and the projection 35 of the hollow seal portion 26 are formed from a solid material and have high rigidity, they can always be reliably pressed against one side 34a of the fabric member 34 with a relatively strong force.

[0037] Furthermore, since the tip 35a of the projection 35 is always elastically pressed against the outer surface of one side 34a of the fabric member 34 by the pressure-applying part 36, regardless of whether the front door 02 is opened or closed, the occurrence of the projection 35 opening up can be suppressed in any state.

[0038] In particular, when the front door 02 is closed, the protrusion 35 is strongly pressed toward one side 34a of the fabric member 34 in conjunction with the pressing force of the joint 26d due to the compression deformation of the hollow seal portion 26, which further suppresses the occurrence of the protrusion 35 opening up.

[0039] As described above, in this embodiment, it is possible to sufficiently suppress misalignment of the tip 35a of the protrusion 35 and the occurrence of gaps between the tip 35a and one side 34a of the fabric member 34. This prevents debris from entering the space 37 and improves the appearance quality without compromising aesthetics.

[0040] Furthermore, in this embodiment, since a second projection 33 is provided on the outer surface of the vehicle exterior sealing portion 30 in addition to the first projection 32, even if there are variations in the mounting accuracy of the weatherstrip 21 to the flange portion 05 of the door opening edge of the vehicle body or in the assembly accuracy of the vehicle body, when the front door 02 is closed, the first projection 32 and the second projection 33 are pressed against the outer surface of the door panel 06, and the variations can be absorbed by a double seal, thus ensuring stable sealing performance. [Second Embodiment] Figure 6 shows a second embodiment of the weatherstrip 21 according to the present invention, wherein a support lip 39 extending in the opposite direction to the projection 35 is provided at one end 26a of the hollow sealing portion 26. This support lip 39 is formed in a substantially flat cross-section and extends along the longitudinal direction of the weatherstrip 21, and in the figure, it has a predetermined width length from the fixed end 39a connected to the one end 26a to the lower end 39b which is the free end. When a force is applied to the projection 35 in the direction of opening (as indicated by the white arrow in the figure), the lower end 39b of the support lip 39 comes into contact with the outer surface of the outer side wall 24 of the vehicle due to a seesaw action with one end 26a as the fulcrum. This reaction force causes a force to act on the projection 35 toward one side 34a of the fabric member 34. As a result, the tip 35a of the projection 35 is biased toward the outer surface of one side 34a of the fabric member 34, further suppressing unnecessary displacement and opening of the mouth.

[0041] Furthermore, as shown in Figure 7, the support lip 39 can also be configured such that its lower end portion 39b is bent into a substantially L-shape in cross-section, and its tip portion 39c abuts against the outer surface of the outer side wall 24 of the vehicle. With this configuration, when a force is applied to the protrusion 35 in the direction of opening, the tip edge of the L-shaped tip portion 39c of the support lip 39 immediately abuts against the outer surface of the outer side wall 24 of the vehicle, applying a strong reaction force to the protrusion 35. This makes it possible to suppress displacement and opening of the protrusion 35 even more quickly.

[0042] The present invention is not limited to the configurations of the embodiments described above, and for example, the cross-sectional shape of the protrusion 35 and the hollow seal portion 26 can be further modified.

[0043] As the automotive weatherstrip based on the embodiments described above, for example, there are those in the following-described modes.

[0044] As one mode thereof, a mounting base portion having a U-shaped cross section that is attached to a flange portion formed along the door opening edge of the vehicle body, a hollow seal portion whose both ends are integrally joined to the outer surface of the mounting base portion and which is elastically contacted by the door panel when the door is closed, and at least covering the outer surface of the mounting base portion, an automotive weatherstrip provided with a cloth member disposed in the vicinity of a portion where one end portion of the hollow seal portion of the mounting base portion is joined, wherein a protrusion for pressing the outer surface of one side portion of the cloth member in a line contact state is provided on the outer surface of one end portion of the hollow seal portion, and one end portion of the hollow seal portion and the protrusion are formed of rubber or a solid material of synthetic resin.

[0045] According to the mode of this invention, since the one side portion of the cloth member is pressed in a line contact state by the tip portion of the protrusion, when the door is closed, when the peripheral portion of the door elastically contacts the hollow seal portion and the hollow seal is crushed and deformed, the protrusion follows this without causing displacement or opening of the mouth, etc., and a stable and reliable contact state of the one side portion of the cloth member by the protrusion can be obtained.

[0046] In particular, since one end portion of the hollow seal portion and the protrusion are formed of a solid material and have high rigidity, it is possible to surely press the one side portion of the cloth member with a relatively strong force at all times. Thereby, even when the hollow seal portion is compressed and deformed, generation of useless opening of the protrusion can be suppressed.

[0047] Therefore, it becomes possible to sufficiently suppress the generation of a gap between the tip portion of the protrusion and the one side portion of the cloth member. As a result, the appearance quality can be improved without impairing the appearance.

[0048] More preferably, the protrusion is formed in a substantially triangular cross section, the tip portion which is the top abuts on the outer surface of the one side portion of the cloth member in a line contact state, and a pressure applying portion for applying a pressing force in the direction of the upper surface of the one side portion of the cloth member to the protrusion is provided at the joining portion of the one end portion of the hollow seal portion and the protrusion.

[0049] According to this embodiment of the invention, since the tip of the projection is subjected to a pressing force by the pressure-applying part toward the upper surface of one side of the fabric member, when the door is closed, it can maintain a line contact state of pressing against the upper surface of one side of the fabric member in combination with the pressing force of the joint due to the compression deformation of the hollow seal part. This makes it possible to suppress the occurrence of a gap between the tip of the projection and one side of the fabric member due to the opening of the projection.

[0050] More preferably, a space is formed inside the projection including one end of the hollow sealing portion and the pressure-applying portion. According to this embodiment of the invention, the edge of one side of the fabric member can be accommodated within the space, and if, for example, an adhesive for preventing curling is applied to the edge of one side of the fabric member, this adhesive can be concealed.

[0051] More preferably, a support lip is provided on the outer surface of one end of the hollow seal portion opposite to the projection, with its tip contacting the outer surface of the outer side wall of the mounting base, and the support lip is characterized in that it supports the projection with a force in the opposite direction to the force in the opening direction of the projection.

[0052] According to an aspect of this invention, when the hollow seal portion is compressed and deformed when the door is closed, a force in the opening direction is applied to the protrusion. As a reaction force, the tip of the support lip is pressed against the outer surface of the outer side wall of the vehicle, and the protrusion is supported by a force in the opposite direction to the opening direction through a seesaw action, thereby further reliably suppressing the opening of the protrusion.
