Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of Korean Patent Application No. 10-2019-0006349 filed on January 17, 2019, in the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application relates to a sealing strip for a vehicle; more particularly, the present application relates to a sealing strip that corresponds to a varying width of a frame molding to ensure sealing performance between a door frame and a vehicle body. Background Art

[0004] The vehicle has a door including a door panel and a door frame connected to the door panel. The door frame defines a window opening opened and closed by a door glass, and a door glass run channel and a sealing strip are attached to the door frame. The door glass run channel may be configured to create a seal between the door frame and the door glass, and the sealing strip may be configured to seal a gap between the door frame and a vehicle body.

[0005] In order to improve the exterior of the door along the upper edge of the door frame, a frame molding, typically made of stainless steel, may be attached to the door frame.

[0006] A frame molding may be attached to at least a portion of a door frame to meet aesthetic design requirements, such as individual design based on a vehicle model. The frame molding may be provided so that its width varies in a longitudinal direction of the door frame. Hereinafter, a frame molding having a varying width that varies in the longitudinal direction of the door frame will be referred to as a "variable frame molding".

[0007] In order to correspond to the varying width of the varying frame molding, the sealing strip may be divided into an outer sealing strip (or also called a separation sealing strip) and an inner sealing strip (or also called a door sealing strip), and the outer sealing strip and the inner sealing strip may be installed separately.

[0008] The outer sealing strip can be mounted to the outer edge of the door frame by a trim mounting member, and the inner sealing strip can be arranged to face the inner side of the vehicle relative to the outer sealing strip on the door frame. As the width of the variable frame trim changes, the size and / or shape of the trim mounting member can be changed, and the installation position of the outer sealing strip can be adjusted by changing the size and / or shape of the trim mounting member, so that the outer sealing strip can be installed to correspond to the variable width of the variable frame trim.

[0009] The trim mounting piece can be coupled to the door frame by double-sided tape and a clamp, and the variable frame trim can be coupled to the door frame by double-sided tape. The inner sealing strip can be coupled to the door frame by a fastening structure, and the outer sealing strip can be coupled to the door frame by the trim mounting piece and the frame trim.

[0010] The door frame may have a groove-shaped retainer, and the inner sealing strip may be mounted on the groove-shaped retainer. Due to the instability of the quality of the retainer, it may be difficult to stably ensure the installation quality of the inner sealing strip.

[0011] Furthermore, an edge of the inner sealing strip and an edge of the outer sealing strip may overlap or separate from each other, which may deteriorate exterior design or exterior quality.

[0012] The inner and outer sealing strips of such a conventional weather strip are separately manufactured and respectively mounted on the door frame to correspond to the varying widths of the varying frame moldings, and thus it may be very difficult to assemble the weather strip, and the assembly quality and exterior quality, etc. may be degraded.

[0013] The above information described in the Background Art section is provided to help understanding the background of the inventive concept, and may include information that should not be considered as any technical concept constituting the prior art known to a person skilled in the art.

[0037] refer to Figure 1 The vehicle door 1 may include a door panel 2 and a door frame 3 connected to the door panel 2 .

[0038] The door frame 3 defines a window opening 5, and the door glass 4 may be fixed to or movably mounted to the window opening 5. A variable frame molding 6 may be attached to the top edge of the door frame 3. The width of the variable frame molding 6 may vary along the longitudinal direction of the door frame 3. That is, the variable frame molding 6 may have a variable width that varies in the longitudinal direction of the door frame 3. For example, in Figure 1 The vehicle door 1 shown in the figure may be a rear door, and the width of the variable frame trim 6 may gradually increase from the B-pillar 7 to the C-pillar 8 (W1<W2). Figure 2 and Figure 3 As shown, the second width W2 (see Figure 3 ) can be greater than the first width W1 of the variable frame trim 6 adjacent to the B-pillar 7 (see Figure 2 )(W1<W2). Due to the variable width of the variable frame bead 6, the exterior design of the vehicle can be improved.

[0039] refer to Figure 2 and Figure 3 The door glass run channel 9 may be attached to the inner periphery of the door frame 3 , and the door glass run channel 9 may create a seal between the door frame 3 and the door glass 4 .

[0040] The door frame 3 may have a mounting flange 41 formed on its outer edge, and the variable frame molding 6 may be attached to the outer surface of the mounting flange 41 by an adhesive tape 13 or the like. The door frame 3 may have a groove-shaped retainer 15 , which may be provided inside the mounting flange 41 .

[0041] According to an exemplary embodiment of the present application, the variable frame molding 6 may have a retainer 50 coupled to the top edge thereof, and the retainer 50 may be made of a resin material, etc. For example, the retainer 50 may be integrally formed with the top edge of the variable frame molding 6 by inserting a molding. The retainer 50 may have a first retaining hook 51, and the first retaining hook 51 may be fitted into a first groove 27 of an outer side sealing strip 11 of a sealing strip 10 to be described below.

[0042] The molding mounting member 55 may be attached to the retainer 15 of the door frame 3 by an adhesive tape 14 or the like, and may have a second retaining hook 56 opposite to the first retaining hook 51 of the retainer 50. The second retaining hook 56 may be fitted into a second groove 28 of an outer side weather strip 11 of a weather strip 10 to be described below.

[0043] The thickness of the trim mounting member 55 can be varied to correspond to the variation in the width of the variable frame trim 6. For example, the trim mounting member 55 can have a thickness such as Figure 2 The first thickness t1 shown corresponds to the first width W1 of the variable frame trim 6, and the trim mounting member 55 may have a Figure 3 The second thickness t2 shown corresponds to the second width W2 of the variable frame trim 6. The second thickness t2 of the trim mounting member 55 adjacent to the C-pillar 8 (see Figure 3 ) may be greater than the first thickness t1 of the trim mounting member 55 adjacent to the B-pillar 7 (see Figure 2 )(t1<t2). That is, the molding mounting member 55 may have a variable thickness, and the variable thickness is varied along the longitudinal direction of the door frame 3 .

[0044] refer to Figure 2 and Figure 3 , the sealing strip 10 according to the exemplary embodiment of the present application may include an outer sealing strip 11 and an inner sealing strip 12 pivotably or bendably connected to the outer sealing strip 11 .

[0045] The outer side weather strip 11 may be disposed between an outer side edge of the door frame 3 and an outer side edge of the vehicle body 16. The outer side weather strip 11 may be attached to the outer side edge of the door frame 3.

[0046] The outer sealing strip 11 may include a base portion 21 mounted to the outer edge of the door frame 3 and an outer lip portion 22 extending from the base portion 21 toward the outer edge of the vehicle body 16. The base portion 21 and the outer lip portion 22 may be made of a softer material such as softer rubber. Since the outer lip portion 22 is easily deformed, the sealing performance of the outer sealing strip 11 can be ensured. When the outer lip portion 22 contacts the outer edge of the vehicle body 16 in a state where the vehicle door 1 is closed, the outer lip portion 22 can seal the gap between the outer edge of the door frame 3 and the outer edge of the vehicle body 16.

[0047] The core 23 may be provided to the base portion 21, and the core 23 may be made of a harder material such as a harder rubber, so that the rigidity of the outer sealing strip 11 can be ensured. The core 23 may include a tubular portion 25, such as Figure 5 As shown, the tubular portion 25 may have a cavity 26 in which a cylindrical portion 35 of the inner sealing strip 12 described below is received. The base portion 21 may cover the upper surface of the core 23 and the upper surface of the tubular portion 25.

[0048] The core 23 may have a pair of grooves 27 and 28, which may include a first groove 27 provided on the outside of the door frame 3 and a second groove 28 provided on the inside of the door frame 3. The first retaining hook 51 of the retainer 50 of the variable frame molding 6 may be fitted into the first groove 27 of the core 23, and the second retaining hook 56 of the molding mounting member 55 may be fitted into the second groove 28 of the core 23, so that the outer weather strip 11 may be mounted in the retainer 15 of the door frame 3. The core 23 may be integrated with the base portion 21 by inserting the molding, so that the core 23 and the base portion 21 may form an integrated single piece.

[0049] The inner sealing strip 12 may be disposed toward the inner side of the vehicle relative to the outer sealing strip 11. The inner sealing strip 12 may include an inner sealing portion 31, the inner sealing portion 31 may have a tubular shape, and a cavity 38 is inside the inner sealing portion 31. The inner sealing portion 31 may have an upper wall 32 and a lower wall 33, the upper wall 32 extends in an arc shape, and the lower wall 33 extends in an inclined direction, and the cavity 38 may be defined by the upper wall 32 and the lower wall 33. The inner sealing strip 12 may have an extension portion 34 extending from the inner sealing portion 31 toward the outer sealing strip 11, and an inner lip portion 37 formed at the bottom end of the inner sealing portion 31. The extension portion 34 may extend from a connection portion of the upper wall 32 and the lower wall 33 toward the outer sealing strip 11, and the inner lip portion 37 may be formed to have a pointed shape at the bottom end of the lower wall 33.

[0050] When the vehicle door 1 is closed, when the upper wall 32 of the inner sealing portion 31 contacts the vehicle body 16 and the inner lip portion 37 of the inner sealing portion 31 contacts the door frame 3 , the inner sealing portion 31 can seal the gap between the door frame 3 and the vehicle body 16 .

[0051] The inner seal strip 12 may be made of a relatively soft material such as relatively soft rubber. The inner seal portion 31 and the inner lip portion 37 are easily deformed, so the sealing performance of the inner seal strip 12 can be ensured.

[0052] The inner sealing strip 12 may include a cylindrical portion 35 that is rotatably received in the cavity 26 of the tubular portion 25. Figure 2 As the cylindrical portion 35 rotates in the cavity 26 of the tubular portion 25 to correspond to the changing width of the frame trim 6, the inner sealing strip 12 can pivot or bend in a predetermined direction (see Figure 2 Since the inner sealing strip 12 can be pivoted or bent relative to the outer sealing strip 11 to correspond to the varying width of the frame molding 6, the inner lip portion 37 of the inner sealing strip 12 can closely contact the door frame 3.

[0053] According to an exemplary embodiment, the cylindrical portion 35 may be integrally formed with an end portion of the extending portion 34 , such that the cylindrical portion 35 can be integrally connected to the inner sealing portion 31 of the inner weather strip 12 .

[0054] The cylindrical portion 35 may have a circular cross section, and the cylindrical portion 35 may be integrally connected to the core 23 of the outer sealing strip 11 through a plurality of bridges 36. The plurality of bridges 36 may be physically connected between the outer surface of the cylindrical portion 35 and the inner surface of the tubular portion 25. The thickness of the plurality of bridges 36 may be sufficient to be elastically deformed. The plurality of bridges 36 may be spaced apart from each other on the outer surface of the cylindrical portion 35 along the cylindrical direction, and each bridge 36 may extend radially from the cylindrical portion 35. When the cylindrical portion 35 of the inner sealing strip 12 rotates around the central axis of the tubular portion 25 of the outer sealing strip 11, each bridge 36 may be elastically deformed, and the cylindrical portion 35 of the inner sealing strip 12 may return to its original position relative to the tubular portion 25 of the outer sealing strip 11 through the plurality of bridges 36. The cylindrical portion 35 of the inner sealing strip 12 may not be separated from the tubular portion 25 of the outer sealing strip 11 by a plurality of bridges 36, but the inner sealing strip 12 may be integrally connected to the outer sealing strip 11. That is, the inner sealing strip 12 and the outer sealing strip 11 may be configured to form an integrated single piece.

[0055] The installation position of the outer sealing strip 11 can be changed to correspond to the changing width W1 or W2 of the frame trim 6 and the thickness t1 or t2 of the trim mounting member 55. Figure 2 and Figure 3 As shown, when the second thickness t2 of the molding installation member 55 adjacent to the C-pillar 8 and the second width W2 of the variable frame molding 6 are greater than the first thickness t1 of the molding installation member 55 adjacent to the B-pillar 7 and the first width W1 of the variable frame molding 6, the installation height h2 (see Figure 3 ) can be higher than the installation height h1 of the outer sealing strip 11 adjacent to the B-pillar 7 (see Figure 2 ).

[0056] According to the exemplary embodiment of the present application, since the installation height of the outer sealing strip 11 changes to correspond to the changing width of the frame molding 6 and the changing thickness of the molding mounting member 55, the cylindrical portion 35 of the inner sealing strip 12 can rotate in the tubular portion 25 of the outer sealing strip 11, and accordingly the inner sealing strip 12 can pivot or bend relative to the outer sealing strip 11, so that the inner sealing strip 12 and the outer sealing strip 11 can be easily assembled or mounted to the door frame 3, and the gap between the door frame 3 and the vehicle body 16 can be tightly sealed.

[0057] In addition, according to the exemplary embodiment of the present application, the outer sealing strip 11 and the inner sealing strip 12 can form an integrated single piece through the tubular portion 25 and the cylindrical portion 35, thereby improving the external quality and installation quality of the sealing strip 10 and reducing its manufacturing cost and assembly labor.

[0058] As described above, according to the exemplary embodiment of the present application, the sealing strip may correspond to the varying width of the varying frame molding to ensure the sealing performance between the door frame and the vehicle body, facilitate the assembly thereof, and improve the exterior quality and installation quality thereof.

[0059] According to an exemplary embodiment of the present application, since the installation height of the outer sealing strip is changed to correspond to the changing width of the frame molding and the changing thickness of the molding mounting member, the cylindrical portion of the inner sealing strip can be rotated in the tubular portion of the outer sealing strip, and accordingly the inner sealing strip can be pivoted or bent relative to the outer sealing strip, so that the inner sealing strip and the outer sealing strip can be easily assembled or installed to the door frame, and the gap between the door frame and the vehicle body can be tightly sealed.

[0060] In addition, according to the exemplary embodiment of the present application, the outer sealing strip and the inner sealing strip can be formed into an integrated single piece by the tubular portion and the cylindrical portion, thereby improving the exterior quality and installation quality of the sealing strip and reducing its manufacturing cost and assembly labor.

[0061] Although the present application has been described above with reference to exemplary embodiments and the accompanying drawings, the present application is not limited thereto, and those skilled in the art to which the present application belongs may obviously change and modify the present application in various different ways without departing from the spirit and scope of the present application as required by the following claims.
