Description

Technical Field

[0001] The present invention relates to a glass run channel for a vehicle door installed on a vehicle door, and more particularly to the technical field of a structure having a molding installed on the outer side of a vehicle interior. Background Art

[0002] There is a vehicle door arranged on the side of the automobile: the vehicle door has a window frame for holding the peripheral edge of the vehicle window glass. On this vehicle door with the vehicle window frame, a glass run channel for sealing the gap between the vehicle window frame and the vehicle window glass is provided.

[0003] The glass run channels disclosed in Patent Documents 1 and 2 are mounted on the window frame from the outside of the vehicle interior. For example, a glass run channel such as the glass run channel disclosed in Patent Document 1 is sometimes used to mount on the window frame from the outside of the vehicle interior due to the need for vehicle exterior design.

[0004] A molding that is long in the vehicle front-rear direction is mounted on the exterior side of the glass run channel of Patent Documents 1 and 2. The upper and lower ends of the molding engage with upper and lower engaging portions provided on the main body of the glass run channel, respectively.

[0006] Patent Document 2: U.S. Patent No. 9114765 Summary of the invention

[0007] -Technical problem to be solved by the invention-

[0008] The glass run channel generally includes a glass run channel front edge portion and a glass run channel rear edge portion extending in the up-down direction along the front edge portion and the rear edge portion of the vehicle window glass, respectively, and a glass run channel upper edge portion extending in the front-to-back direction from the upper end portion of the glass run channel front edge portion to the upper end portion of the glass run channel rear edge portion. In this case, a molding is installed on the exterior side of the glass run channel upper edge portion.

[0009] Sometimes, a front side sealing portion extending in the up-down direction along the front part of the door is provided in front of the front edge of the glass run channel. In this case, a structure can be conceived in which the upper edge of the glass run channel is extended forward to integrate the front side sealing portion with the upper edge of the glass run channel. If this structure is adopted, the molding also needs to be extended forward along the upper edge of the glass run channel, and the extension amount is equal to the amount by which the upper edge of the glass run channel has been extended forward.

[0010] When the glass run channel having the molding is assembled to the window frame, the front side sealing portion may be bent from the vicinity of the root to cause elastic deformation along the front edge of the door. When the glass run channel having the molding is carried, the front side sealing portion may be bent from the vicinity of the root. If the front side sealing portion is bent, the bending force may also reach the upper edge of the glass run channel to cause elastic deformation of the upper edge of the glass run channel. As a result, the following problem may occur: the upper side engaging portion or the lower side engaging portion formed on the upper edge of the glass run channel may be separated from the molding, resulting in a deterioration in the appearance. If the molding is separated, it is necessary to reinstall the separated molding, which is labor-intensive.

[0011] The present invention has been made in view of the above problems and aims to ensure that the molding will not come off the upper edge of the glass run channel even if bending force is applied to the front side sealing portion installed at the front portion of the door, thereby suppressing the occurrence of inconvenience.

[0012] -Technical solutions for solving technical problems-

[0013] The window frame is formed on the upper edge of the window frame and extends toward the outer side of the vehicle interior, and the window frame extends in a manner to form a window opening on the vehicle door, and the glass run channel for the vehicle door seals the gap between the window frame and the window glass, characterized in that: the glass run channel for the vehicle door comprises: a front edge of the glass run channel, which extends in the up-down direction along the front edge of the window frame; a rear edge of the glass run channel, which extends in the up-down direction along the rear edge of the window frame; a front sealing portion, which is arranged at a position away from the front edge of the glass run channel toward the front of the vehicle and is installed at the front part of the vehicle of the vehicle door; an upper edge of the glass run channel, which extends from the upper end of the front sealing portion through The window pane is configured to extend from the upper end of the front edge of the glass run channel to the upper end of the rear edge of the glass run channel, and an upper upper edge engaging portion is provided at the upper portion of the outer side of the vehicle exterior of the upper edge of the glass run channel, and a lower upper edge engaging portion is provided at the lower portion of the outer side of the vehicle exterior of the upper edge of the glass run channel; a molding extending in the front-rear direction of the vehicle along the outer side of the vehicle exterior of the upper edge of the glass run channel, and mounted on the upper edge of the glass run channel in a state of engaging with the upper upper edge engaging portion and the lower upper edge engaging portion; and a molding retaining component made of a harder material than a portion of the upper edge of the glass run channel that contacts the vehicle window glass, and fixed to a portion of the upper edge of the glass run channel that is closer to the front side of the vehicle than the front edge of the glass run channel, and having a front side engaging portion, the front side engaging portion protruding toward the outer side of the vehicle exterior than the outer surface of the upper edge of the glass run channel and engaging with the molding.

[0014] According to this configuration, the molding can be mounted on the upper edge of the glass run channel by engaging the molding with the upper upper edge engaging portion and the lower upper edge engaging portion of the upper edge of the glass run channel. In this state, the molding is also engaged with the front engaging portion of the molding holding member. Since the molding holding member is located closer to the front side of the vehicle than the front edge of the glass run channel, it is engaged with the portion of the molding near the front sealing portion. Moreover, since the molding holding member is made of a hard material, the front engaging portion is unlikely to be deformed, and once engaged, the front engaging portion is unlikely to be separated from the molding. Thus, for example, when the glass run channel is mounted on the window frame or when the glass run channel is transported, even if the front sealing portion is greatly bent and the upper edge of the glass run channel is slightly elastically deformed, the molding can be prevented from being separated from the upper edge of the glass run channel.

[0015] The second invention is characterized in that the molding holding member includes an embedded plate portion embedded in an upper side portion of the glass run channel.

[0016] According to this configuration, the molding holding member can be firmly fixed to the upper edge of the glass run channel by embedding the embedded plate portion in the upper edge of the glass run channel. The molding holding member can be formed by insert molding so that the embedded plate portion is embedded in the upper edge of the glass run channel, or the embedded plate portion can be embedded in the upper edge of the glass run channel by two-color molding. When the two-color molding method is used, for example, after the resin material for the molding holding member is injection molded, the rubber material for the upper edge of the glass run channel can be injection molded.

[0017] The third aspect of the invention is characterized in that: the upper edge of the glass run channel includes a core component, the core component is made of a hard material that is harder than the part of the upper edge of the glass run channel that contacts the vehicle window glass, and the embedded plate portion is arranged below the core component and extends along the core component in the front-rear direction of the vehicle.

[0018] According to this configuration, when a force in the molding detachment direction acts on the front engaging portion of the molding retaining member due to bending of the front sealing portion, the deformation or displacement of the embedded plate portion is suppressed by the core member, so that the molding is more difficult to detach from the front engaging portion.

[0019] The fourth aspect of the invention is characterized in that: the upper side upper snap-in portion and the lower side upper snap-in portion are respectively composed of protrusion portions, the protrusion portions protrude from the vehicle interior surface of the upper side portion of the glass run channel toward the outside of the vehicle interior and extend along the front-rear direction of the vehicle, and the front side snap-in portion of the molding retaining component is arranged on the vehicle front side of the lower side upper snap-in portion on an extension line of the lower side upper snap-in portion extending toward the front side of the vehicle.

[0020] According to this configuration, since the front side engaging portion of the molding retaining component is arranged on the extension line of the lower upper side engaging portion of the glass run channel upper edge portion, the cross-sectional shape of the engaging portion of the molding can be made uniform in the length direction, thereby facilitating the manufacture of the molding, and at the same time, the molding can be engaged with both the lower upper side engaging portion of the glass run channel upper edge portion and the front side engaging portion of the molding retaining component and firmly fixed.

[0021] The fifth aspect of the invention is characterized in that: a protrusion protruding toward the outside of the vehicle interior is provided at a portion of the upper edge of the glass run channel that is closer to the front side of the vehicle than the front edge of the glass run channel, a front abutment portion is provided on the front side of the vehicle of the molding, the front abutment portion is arranged to be able to abut against the protrusion from the front side of the vehicle, and the molding retaining component has a positioning portion buried inside the protrusion.

[0022] That is, when the door is opened or closed many times or the door is closed with force, the molding and the upper edge of the glass run channel are independent components, so the molding may be offset toward the rear of the vehicle. If the molding is offset toward the rear, it may interfere with other components arranged at the rear of the door, resulting in poor appearance.

[0023] According to this configuration, when the molding is mounted on the upper edge of the glass run channel, the front side abutting portion of the molding is arranged to abut against the protruding portion of the upper edge of the glass run channel from the front side of the vehicle. Since the positioning portion made of a hard material is embedded in the protruding portion, the deformation of the protruding portion is suppressed by the positioning portion. Therefore, when the molding is to be displaced toward the rear side so that the front side abutting portion abuts against the protruding portion of the upper edge of the glass run channel, the displacement of the molding toward the rear side is fully suppressed by the protruding portion and the positioning portion. In this way, the molding does not interfere with other components, and a good appearance can be maintained.

[0024] A sixth aspect of the invention is characterized in that the positioning portion of the molding holding member protrudes toward the outer side of the vehicle interior.

[0025] According to this configuration, the positioning portion can be ensured to have a long dimension in the vehicle width direction. Therefore, even if the front side contact portion of the molding is slightly displaced in the vehicle width direction, displacement of the molding toward the vehicle rear side can be suppressed.

[0026] The seventh invention is characterized in that a filling portion is provided in the positioning portion of the molding holding member, and the filling portion is filled with a material for forming the upper edge portion of the glass run channel from the inner side of the positioning portion.

[0027] According to this configuration, since the material forming the upper edge of the glass run channel is filled into the positioning portion of the molding holding member, the positioning portion is firmly fixed to the upper edge of the glass run channel, thereby further improving the positioning portion's effect of suppressing displacement of the molding toward the rear side of the vehicle.

[0028] - Effects of the Invention -

[0029] As described above, according to the present invention, since the molding retaining component made of a hard material is fixed to the vehicle front side of the upper edge portion of the glass run channel, and the front side engaging portion that protrudes toward the outer side of the vehicle interior and engages with the molding is provided on the molding retaining component, even if a bending force is applied to the front side sealing portion installed on the front portion of the door, the molding will not be separated from the upper edge portion of the glass run channel, thereby being able to suppress the occurrence of adverse conditions.

DETAILED DESCRIPTION

[0040] The following is a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be noted that the following description of the preferred embodiments is essentially for illustration only and is not intended to limit the present invention, its application objects or its use.

[0041] Figure 1 This is a view of a vehicle door 1 including a glass run channel 20 for a vehicle door according to an embodiment of the present invention, viewed from the outside of a vehicle compartment. The vehicle door 1 is a front door provided on the front side of a side portion of a vehicle (not shown), and the vehicle door 1 opens and closes an opening (not shown) formed on the front side of the side portion of the vehicle. There is also a case where a rear door is provided on the side portion of the vehicle, but it is not shown. It should be noted that in the description of this embodiment, the front side of the vehicle is referred to as "front" and the rear side of the vehicle is referred to as "rear".

[0042] The automobile door 1 has a door body 2 constituting a substantially lower half of the automobile door 1 and a window frame 3 constituting a substantially upper half of the automobile door 1. The front end of the door body 2 is mounted on a pillar of the vehicle body via a hinge having a rotating shaft extending in the up-down direction, but not shown in the figure. The door body 2 is composed of an inner plate (not shown) and an outer plate 2a, and the inner plate and the outer plate 2a are made of steel plates or the like. The interior of the door body 2 can accommodate a window glass 4 that performs a lifting action and a lifting device (not shown) for lifting the window glass 4.

[0043] The window frame 3 plays the role of a frame that holds the peripheral edge of the window glass 4, and extends to form a window opening 7. The window opening 7 formed by the window frame 3 is opened and closed by the window glass 4. Figure 5 and Figure 6 As shown, the window frame 3 in this embodiment is formed by combining a first panel member 5 and a second panel member 6 which are formed by press-forming a steel plate or the like.

[0044] like Figure 1As shown, the window frame 3 is composed of a front side frame portion (frame front edge portion) 3a, a rear side frame portion (frame rear edge portion) 3b and a frame upper edge portion 3c. The front side frame portion 3a protrudes upward from the front portion of the upper edge of the door body 2 and extends along the front edge portion of the window glass 4. The rear side frame portion 3b protrudes upward from the rear portion of the upper edge of the door body 2 and extends along the rear edge portion of the window glass 4. The rear side frame portion 3b extends to a position higher than the front side frame portion 3a. The frame upper edge portion 3c extends from the upper end of the front side frame portion 3a to the upper end of the rear side frame portion 3b in the front-to-back direction along the roof side edge portion (not shown) of the vehicle body. It should be noted that the frame upper edge portion 3c is usually curved, but the shape of the frame upper edge portion 3c is not limited to the shape shown in the figure, and can also be in a shape that is curved upward as a whole. Moreover, the position of the curved portion and the inclination angle of the frame upper edge portion 3c can be arbitrarily set according to the roof shape of the vehicle body. The front side frame portion 3 a of the window frame 3 is provided continuously to the front portion of the door body 2 , and the front portion of the front side frame portion 3 a is located above the front portion of the door body 2 .

[0045] like Figure 5 and Figure 6 As shown, a glass run channel mounting plate portion 10 extending toward the outside of the vehicle interior is formed on the vehicle window frame 3. It should be noted that Figure 5 is along Figure 3 The cross-sectional view taken along the V-V line. Figure 6 is along Figure 3 Therefore, although the glass run groove mounting plate portion 10 does not exist in the original figure, for the convenience of explanation, Figure 5 and Figure 6 The glass run channel mounting plate portion 10 is also shown.

[0046] The first panel member 5 and the second panel member 6 constituting the window frame 3 are members which can also be called an inner panel and an outer panel, respectively. The portion of the first panel member 5 located above the window opening 7 extends toward the outside of the vehicle interior. The portion of the second panel member 6 located above the window opening 7 also extends toward the outside of the vehicle interior. By overlapping and joining the first panel member 5 and the second panel member 6 in the up-down direction, a glass run channel mounting plate portion 10 extending continuously in the front-rear direction is formed.

[0047] (Structure of glass run channel)

[0048] The glass run channel 20 is assembled to the window frame 3 from the outside of the vehicle interior, and functions as a seal for sealing a gap between the window frame 3 and the window glass 4 .

[0049] Also Figure 2As shown, the glass run channel 20 includes a glass run channel front edge 21, a glass run channel rear edge 22, a front side sealing portion 23, and a glass run channel upper edge 24. The above-mentioned parts 21 to 24 are integrated into one component. A molding 40 is installed on the outer side of the vehicle interior of the glass run channel upper edge 24, and in order to prevent the molding 40 from detaching and suppressing the position shift of the molding 40, a molding 40 is also included. Figure 4 The molding holding member 50 shown will be described in detail later. The molding 40 and the molding holding member 50 are members constituting a part of the glass run channel 20 .

[0050] The glass run channel front edge 21 is a portion extending in the vertical direction along the front side frame portion 3a of the vehicle window frame 3. The glass run channel rear edge 22 is a portion extending in the vertical direction along the rear side frame portion 3b of the vehicle window frame 3. The front side sealing portion 23 is a portion arranged to leave the front side frame portion 3a toward the front and installed in the front part of the vehicle door 1, and is sometimes referred to as a partition sealing portion. The upper end of the front side sealing portion 23 is located at the upper end of the front side of the front side frame portion 3a. The front side sealing portion 23 extends downward from the upper end of the front part of the front side frame portion 3a along the front part of the front side frame portion 3a, and further extends downward along the front part of the vehicle door body 2. The length of the front side sealing portion 23 is set shorter than the length of the glass run channel front edge 21, and the lower end of the front side sealing portion 23 is located at a position higher than the lower end of the glass run channel front edge 21.

[0051] The glass run channel upper edge 24 extends in the front-to-back direction from the upper end of the front side sealing portion 23 through the upper end of the glass run channel front edge 21 to the upper end of the glass run channel rear edge 22. The front side sealing portion 23, the glass run channel front edge 21, and the glass run channel rear edge 22 are integrated with each other at a predetermined interval in the front-to-back direction by the glass run channel upper edge 24. The glass run channel upper edge 24 extends along the frame upper edge 3c of the window frame 3, and is gently curved so as to be located upward as it approaches the rear side. The rear side of the glass run channel upper edge 24 protrudes further rearward than the glass run channel rear edge 22, but the protruding shape may be set as required.

[0052] The glass run channel 20 is formed by combining an extrusion-molded portion obtained by extrusion molding and a mold-molded portion obtained by mold molding. Figure 2 As shown in FIG. 1 , the portion sandwiched by the boundary lines L1, L2, and L5 (shown by dashed lines) near the boundary portion between the glass run channel upper edge 24 and the glass run channel front edge 21 of the glass run channel 20 is a molded portion. The portion sandwiched by the boundary lines L3 and L4 (shown by dashed lines) near the boundary portion between the glass run channel upper edge 24 and the glass run channel rear edge 22 of the glass run channel 20 is also a molded portion. The portion other than the above portions is an extrusion-molded portion.

[0053] like Figure 5 As shown in FIG. 1 , the upper edge portion 24 of the glass run channel includes a main body 25 made of a rubber-like elastic material such as an elastomer, and a core member 26 made of a harder material than the material making up the main body 25. The main body 25 is a portion that does not include the core member 26 described later, and examples thereof include rubber such as EPDM (ethylene propylene rubber), TPE (thermoplastic elastomer) such as TPO (olefin) and TPS (styrene), and the rubber or TPE may be a sponge material or a solid material, and is easily elastically deformed.

[0054] The main body 25 includes an upper wall portion 25a extending along the upper surface of the glass run channel mounting plate portion 10, a lower wall portion 25b extending along the lower surface of the glass run channel mounting plate portion 10, and an interior side wall portion 25c extending downward from the exterior side of the upper wall portion 25a and connected to the exterior side of the lower wall portion 25b. The interior side wall portion 25c is formed to protrude downward from the lower wall portion 25b.

[0055] An upper sealing lip 27 is integrally formed on the upper surface of the upper wall portion 25a. The upper sealing lip 27 protrudes upward from the upper surface of the upper wall portion 25a, and is a portion for contacting with a vehicle body panel (not shown) when the vehicle door 1 is in a closed state to elastically deform, thereby sealing the gap between the vehicle door 1 and the vehicle body panel. A plurality of protruding pieces 28 are formed on the lower surface of the upper wall portion 25a to protrude downward. These protruding pieces 28 contact with the upper surface of the glass run channel mounting plate portion 10 to elastically deform.

[0056] A lower plate portion 29 is formed on the lower surface of the lower wall portion 25b by die molding. The lower plate portion 29 comes into contact with the vehicle interior surface of an exterior member (not shown) and is elastically deformed.

[0057] The main body 25 is provided with an installation unit for installing the molding 40. Specifically, an upper side upper side engaging portion 25d and a lower side upper side engaging portion 25e are provided at the upper and lower parts of the vehicle exterior wall portion 25c on the vehicle exterior side of the main body 25, respectively, and the installation unit is constituted by the upper side upper side engaging portion 25d and the lower side upper side engaging portion 25e. The upper side upper side engaging portion 25d is constituted by a protrusion portion that protrudes from the upper part of the vehicle exterior wall portion 25c toward the vehicle exterior side and then bends upward. The lower side upper side engaging portion 25e is constituted by a protrusion portion that protrudes from the lower part of the vehicle exterior wall portion 25c toward the vehicle exterior side and then bends downward. Furthermore, an intermediate protrusion portion 25f is formed in the middle part of the vehicle exterior wall portion 25c in the up-down direction, and the intermediate protrusion portion 25f protrudes toward the vehicle exterior side. The upper side engaging portion 25d, the lower side upper side engaging portion 25e, and the intermediate protrusion portion 25f each have the same shape that is continuous in the vehicle front-rear direction.

[0058] An upper protrusion 25g is formed on the vehicle interior outer side portion of the upper wall portion 25a, protruding toward the vehicle interior outer side and extending in the front-rear direction. A lower protrusion 25h is formed on the lower portion of the vehicle interior outer side wall portion 25c, protruding downward and extending in the front-rear direction.

[0059] (Structure of the core member 26)

[0060] The core member 26 is embedded in the main body 25. As the material of the core member 26, for example, a hard resin (for example, a resin mixed with talc or glass fiber), aluminum alloy, steel, stainless steel or other hard materials can be used, and it is a high-rigidity material harder than the material of the main body 25. The core member 26 has an upper plate portion 26a embedded in the upper wall portion 25a of the main body 25, a lower plate portion 26b embedded in the lower wall portion 25b, and a side plate portion 26c embedded in the outer wall portion 25c of the vehicle interior, and the upper plate portion 26a, the lower plate portion 26b and the side plate portion 26c are formed as one piece.

[0061] The glass run channel upper edge 24 of the glass run channel 20 is an extrusion-molded portion, and thus has a straight shape after molding. On the other hand, since the frame upper edge 3c of the vehicle window frame 3 is bent as described above, when the glass run channel upper edge 24 is mounted on the frame upper edge 3c of the vehicle window frame 3, it is necessary to bend the glass run channel upper edge 24 so that the shape of the glass run channel upper edge 24 corresponds to the shape of the frame upper edge 3c. At this time, since not the entire body 25 is a hard component but only the core component 26 is a hard component, the rigidity of the glass run channel upper edge 24 is not increased to more than the necessary rigidity, so that the glass run channel upper edge 24 can have appropriate rigidity. In this way, the force required to bend the glass run channel upper edge 24 is small.

[0062] (Structure of fillet 40)

[0063] The molding 40 is a component constituting the exterior appearance of the vehicle, and can be called a decorative component, for example. The molding 40 can be made of a metal plate such as aluminum or stainless steel, a hard resin plate, or the like, or can be a component in which a sheet or film material is attached to the exterior surface of these plates, or can be a component that is painted. The molding 40 can be a stamped product or an extruded product.

[0064] like Figure 1 As shown, the molding 40 is formed in a shape that is long in the front-rear direction along the vehicle interior surface of the glass run channel upper edge 24. The front end of the molding 40 is located near the front end of the glass run channel upper edge 24, and the rear end of the molding 40 is located near the rear end of the glass run channel upper edge 24. The molding 40 is curved along the frame upper edge 3c.

[0065] like Figure 5As shown, at the upper part of the molding 40, the upper curved portion 41 is provided so as to bend toward the inner side of the vehicle interior and then bend toward the lower side. At the lower part of the molding 40, the lower curved portion 42 is provided so as to bend toward the inner side of the vehicle interior and then bend toward the upper side. By inserting the upper curved portion 41 of the molding 40 between the upper upper side engaging portion 25d and the upper protruding portion 25g of the glass run channel upper side portion 24, the upper curved portion 41 is engaged in a manner of hooking the upper upper side engaging portion 25d from the upper side and the inner side of the vehicle interior. By inserting the lower curved portion 42 of the molding 40 between the lower upper side engaging portion 25e and the lower protruding portion 25h of the glass run channel upper side portion 24, the lower curved portion 42 is engaged in a manner of hooking the lower upper side engaging portion 25e from the lower side and the inner side of the vehicle interior. In this manner, the molding 40 can be attached to the glass run channel upper side portion 24.

[0066] It should be noted that when the molding 40 is mounted on the glass run channel upper side 24, for example, the lower curved portion 42 may be hooked on the lower upper side engaging portion 25e, and then the molding 40 may be rotated upward around the vicinity of the lower upper side engaging portion 25e, and then the upper curved portion 41 may be hooked on the upper upper side engaging portion 25d. Conversely, the upper curved portion 41 may be hooked on the upper upper side engaging portion 25d, and then the lower curved portion 42 may be hooked on the lower upper side engaging portion 25e.

[0067] By pressing the upper curved portion 41 of the molding 40 onto the upper upper side engaging portion 25d from the outside of the vehicle interior, each portion can be elastically deformed and engaged with the upper upper side engaging portion 25d. By pressing the lower curved portion 42 of the molding 40 onto the lower upper side engaging portion 25e from the outside of the vehicle interior, each portion can be elastically deformed and engaged with the lower upper side engaging portion 25e.

[0068] When the molding 40 is attached to the glass run channel upper edge portion 24, since the upper protrusion 25g of the glass run channel upper edge portion 24 contacts the upper portion of the molding 40 and is elastically deformed, a gap is unlikely to be formed between the upper protrusion 25g and the upper portion of the molding 40. In addition, the lower protrusion 25h contacts the lower portion of the molding 40 and is elastically deformed. Since the intermediate protrusion 25f of the glass run channel upper edge portion 24 contacts the vehicle interior surface of the molding 40 and is elastically deformed, the molding 40 can be prevented from rattling.

[0069] like Figure 3 and Figure 7 As shown, a front plate portion (front side contact portion) 43 bent toward the inner side of the vehicle compartment is provided at the front portion of the molding 40. The front plate portion 43 extends in the up-down direction.

[0070] (Structure of molding holding member 50)

[0071] like Figure 3 and Figure 4 As shown, the molding holding member 50 is fixed to the glass run channel upper edge 24 at a position forward of the glass run channel front edge 21. The molding holding member 50 can prevent the front side of the molding 40 from coming off the glass run channel upper edge 24 and prevent the molding 40 from moving backward.

[0072] That is, in the present embodiment, since the glass run channel 20 includes the front seal portion 23, the front seal portion 23 may be greatly bent in the process of conveying the glass run channel 20 having the molding 40. When the glass run channel 20 having the molding 40 is assembled to the window frame 3, the front seal portion 23 may be bent from the vicinity of the root to be elastically deformed along the front edge of the door 1. If the front seal portion 23 is greatly bent, the bending force may also reach the glass run channel upper edge portion 24 to elastically deform the glass run channel upper edge portion 24. As a result, the upper upper edge engaging portion 25d and the lower upper edge engaging portion 25e formed on the glass run channel upper edge portion 24 may be separated from the molding 40, resulting in a deterioration in the appearance.

[0073] When the door 1 is opened or closed many times or the door 1 is closed with force, the molding 40 may be displaced toward the rear side of the vehicle because the molding 40 and the upper edge 24 of the glass run channel are independent components. If the molding 40 is displaced toward the rear side, it may interfere with other components disposed at the rear side of the door 1, resulting in poor appearance.

[0074] In order to solve these problems, a molding holding member 50 is provided. The molding holding member 50 is a member made of a harder material than the portion (rubber-like elastic material) of the glass run channel upper edge portion 24 that contacts the window glass 4 or an external member. As the material of the above-mentioned member, for example, the same material as the above-mentioned core member 26 can be cited, but it is not limited thereto.

[0075] like Figure 8 As shown in FIG. 5 , the molding holding member 50 is formed into a shape that is long in the front-rear direction. Figure 4 As shown, the molding holding member 50 is provided to be inclined at the same angle as the inclination angle of the front portion of the glass run channel upper edge portion 24, and thus is positioned upward as it goes to the rear side. The molding holding member 50 includes an embedded plate portion 51 embedded in the glass run channel upper edge portion 24, a front side engaging portion 52, and a positioning portion 53.

[0076] like Figure 6As shown, the embedded plate portion 51 is arranged below the lower plate portion 26b of the core component 26, extends in the front-to-back direction along the core component 26, and also extends in the interior-exterior direction of the vehicle interior. The dimension of the embedded plate portion 51 in the front-to-back direction is set to be longer than the dimension of the embedded plate portion 51 in the interior-exterior direction of the vehicle interior. There is a rubber-like elastic material that makes up the lower plate portion 29 between the lower plate portion 26b of the core component 26 and the front end portion of the embedded plate portion 51, and the rubber-like elastic material is fixed to the upper surface of the embedded plate portion 51. The rubber-like elastic material that makes up the lower plate portion 29 is also fixed to the lower surface of the embedded plate portion 51. Therefore, the embedded plate portion 51 is fixed in a state of being embedded in the lower plate portion 29.

[0077] The front engaging portion 52 is formed integrally with the embedded plate portion 51, and is composed of a protruding strip portion that protrudes from the outer side of the embedded plate portion 51 toward the outer side of the vehicle interior, bends downward, and extends in the front-to-back direction. The front engaging portion 52 may be formed continuously or discontinuously in the front-to-back direction. The front engaging portion 52 is arranged in front of the lower upper engaging portion 25e and is located on the extension line of the lower upper engaging portion 25e extending toward the front side. That is, the lower upper engaging portion 25e is not provided to the front part of the glass run channel upper side 24, and is no longer provided before reaching the front engaging portion 52. The front engaging portion 52 extends forward from the front part of the lower upper engaging portion 25e. The lower upper engaging portion 25e and the front engaging portion 52 may be connected without a gap, or there may be a gap between the lower upper engaging portion 25e and the front engaging portion 52.

[0078] The front engaging portion 52 protrudes toward the outside of the vehicle interior from the vehicle interior exterior surface of the glass run channel upper edge portion 24, and engages with the lower curved portion 42 of the molding 40 from below and inside the vehicle interior. Since the front engaging portion 52 is formed of a hard material, once engaged with the lower curved portion 42 of the molding 40, the lower curved portion 42 is unlikely to be separated from the glass run channel upper edge portion 24. The front engaging portion 52 and the lower upper edge engaging portion 25e can be engaged with the lower curved portion 42 simultaneously when the molding 40 is installed.

[0079] A lower protrusion 54 that protrudes downward and extends in the front-rear direction is formed at the lower portion of the front engaging portion 52 of the molding holding member 50. The lower curved portion 42 of the molding 40 is inserted between the front engaging portion 52 and the lower protrusion 54. The lower protrusion 54 is located on an extension line of the lower protrusion 25h of the glass run channel upper side 24 extending forward.

[0080] like Figure 7 As shown in FIG. 2 , a protrusion 30 is provided at a portion of the glass run channel upper edge 24 that is further forward than the glass run channel front edge 21 and that protrudes toward the outside of the vehicle interior. Figure 4As shown in FIG. 1 , the protrusion 30 is located directly above the upper end of the front side sealing portion 23. The protrusion 30 is formed into a shape that is long in the vertical direction. Figure 3 As shown, when the molding 40 is mounted on the upper edge portion 24 of the glass run channel, the protrusion 30 is covered from the outside of the vehicle interior by the front portion of the molding 40 .

[0081] The front plate portion 43 of the molding 40 is arranged at a position further forward than the protrusion 30 of the upper edge portion 24 of the glass run channel, and the front plate portion 43 and the protrusion 30 overlap each other when viewed from the front-back direction. In this way, the positional relationship between the front plate portion 43 and the protrusion 30 is such that the front plate portion 43 can abut against the protrusion 30 from the front side. When the molding 40 is located at the normal position (the center position of the tolerance range), the front plate portion 43 may also be away from the protrusion 30 toward the front, in which case, the positional relationship between the front plate portion 43 and the front surface of the protrusion 30 is such that they face each other with a gap. The front plate portion 43 may also be in contact with the front surface of the protrusion 30.

[0082] A positioning portion 53 of the molding holding member 50 is embedded in the protruding portion 30. The positioning portion 53 protrudes toward the outside of the vehicle interior and is Figure 8 As shown, the protrusion 30 is formed to be long in the vertical direction.

[0083] like Figure 7 As shown in FIG. 1 , the positioning portion 53 has a filling portion 53a into which the rubber elastic material of the molded portion is filled from the inner side of the vehicle interior of the positioning portion 53. The filling portion 53a is formed in a shape that is open toward the inner side of the vehicle interior before the positioning portion 53 is embedded. When the positioning portion 53 is embedded, the rubber elastic material flows into and fills the filling portion 53a. In this way, the positioning portion 53 is firmly fixed to the upper side portion 24 of the glass run channel.

[0084] When the molding 40 is about to move backward, the front plate portion 43 contacts the protrusion 30 from the front. At this time, since the positioning portion 53 made of a hard material is embedded in the protrusion 30 and the positioning portion 53 is integrated with the embedded plate portion 51, the protrusion 30 is difficult to deform and move backward. In this way, the molding 40 can be prevented from moving backward.

[0085] The molding holding member 50 may be molded on the glass run channel upper side portion 24 by insert molding. That is, when the mold molding portion of the glass run channel upper side portion 24 is molded, a mold (not shown) that opens and closes is used, the molding holding member 50 is held on the mold, the mold is closed, and then a material is injected into the cavity, thereby enabling the molding holding member 50 to be integrally molded with a portion of the molding holding member 50 embedded in the mold molding portion.

[0086] The method is not limited to the insert molding method, and for example, a two-color molding method, a mold slide injection molding method, etc. may be used. In this case, after the molding holding member 50 is molded with a resin material in the mold, the mold is replaced, the molding holding member 50 is held in a new cavity, and a rubber elastic material is injected to mold the glass run channel upper edge portion 24. In this way, the molding holding member 50 and the glass run channel upper edge portion 24 can be integrally molded.

[0087] Alternatively, the molding holding component 50 may be fixed to the glass run channel upper edge 24 after the molding holding component 50 and the glass run channel upper edge 24 are formed separately.

[0088] (Functions and Effects of Implementation Methods)

[0089] As described above, according to the present embodiment, since the molding retaining component 50 made of a hard material is fixed to the front side of the upper edge portion 24 of the glass run channel, and the front side engaging portion 52 that protrudes toward the outer side of the vehicle interior and engages with the molding 40 is provided on the molding retaining component 50, even if a bending force is applied to the front side sealing portion 23 installed on the front portion of the vehicle door 1, the molding 40 will not be separated from the upper edge portion 24 of the glass run channel, thereby being able to suppress the occurrence of adverse situations.

[0090] When the molding 40 is displaced toward the rear side due to the opening and closing of the door 1, and the front plate portion 43 of the molding 40 abuts against the protrusion 30 of the upper edge portion 24 of the glass run channel, the displacement of the molding 40 toward the rear side is sufficiently suppressed by the protrusion 30 and the positioning portion 53 of the molding holding member 50. In this way, the molding 40 does not interfere with other components (such as components of the rear door), thereby maintaining a good appearance.

[0091] The above embodiments are merely illustrative in all respects and should not be interpreted as limiting. Moreover, modifications and changes within the equivalent scope of the claims are included within the scope of the present invention.
