Description

[Technical Field]

[0001] The present invention relates to a mounting structure for a glass run that is attached to the inner periphery of a sash portion of a door that opens and closes an opening in the body of an automobile, and that guides the sliding movement of the door glass. [Background technology]

[0002] As is well known, in automobiles with so-called pressed doors (full door type), the glass run that stably guides the door glass as it rises and falls is held in place by being sandwiched between the flanges of the inner panel of the sash section.

[0003] FIG. 1 is a side view of an automobile to which a conventional glass run and the glass run of the present invention are attached, and FIG. 8 is a cross-sectional view taken along line AA in FIG. 1, showing the attachment structure of the conventional glass run.

[0004] 1, sash portions 4, 5 are provided at the upper end of door bodies 2a, 3a of front door 2 and rear door 3, which are formed as press doors of an automobile 1, and glass runs 6, 7 are attached to the inner peripheries of the sash portions 4, 5. For the sake of convenience, the following description will focus on the glass run 6 on the front door 2 side.

[0005] As shown in FIG. 8, the sash portion 4 has an inner panel 9 formed as a double inner and outer structure consisting of a first vehicle interior panel 9a and a second vehicle interior panel 9b, which are joined together by spot welding or the like to form an upper connecting flange 9c and a lower connecting flange 9d.

[0006] As shown in Figure 8, the glass run 6 includes an exterior side wall 11 and an interior side wall 12 that guide the door glass 10 as it moves up and down, a mounting portion 13 with a U-shaped cross section that connects the exterior side wall 11 and the interior side wall 12, and an interior molding lip 14 that is integrally formed with the lower end of the interior side wall 12 in the figure.

[0007] The exterior side wall 11 has a first retaining lip 11a protruding toward the interior side wall 12 at the end opposite the mounting portion 13, and a molding portion 11b provided on the outer surface. On the other hand, the interior side wall 12 has a second retaining lip 12a protruding toward the exterior side wall 11 on the inner surface thereof, which cooperates with the first retaining lip 11a to guide the door glass 10 in sliding movement, and a protrusion 15 protruding toward the molding lip 14 is integrally provided at the lower end.

[0008] The mounting portion 13 is adapted to be fitted and fixed to the upper connecting flange 9c of the inner panel 9 from the outside of the vehicle via a retaining groove 13a formed inside, and a contact lip 13b is provided on the underside thereof for elastic contact with the tip surface of the door glass 10 when in the raised position.

[0009] The molding lip 14 forms a fitting groove 16 between itself and the vehicle interior side wall 12, and the lower connecting flange 9d fitted into this fitting groove 16 is clamped in cooperation with the protrusion 15 of the vehicle interior side wall 12 and held by the lower connecting flange 9d.

[0010] In this way, the glass run 6 is attached to the inner panel 9 of the sash portion 4 via the upper connecting flange 9c and the lower connecting flange 9d, which are respectively fitted into the retaining groove 13a of the mounting portion 13 and the fitting groove 16 between the vehicle interior side wall 12 and the molding lip 14. [Prior art documents] [Patent documents]

[0011] [Patent Document 1] Patent No. 6913545 Summary of the Invention [Problem to be solved by the invention]

[0012] However, as mentioned above, the conventional glass run 6 is designed to hold the lower connecting flange 9d of the inner panel 9 of the sash portion 4 simply by sandwiching it between the molding lip 14 and the protrusion 15 of the interior side wall 12, so there is a risk that this holding force may not be sufficient.

[0013] Therefore, there is a risk that the molding lip 14 may accidentally come off the lower connecting flange 9d due to, for example, vibration of the vehicle body or its own weight, which may result in a deterioration in the appearance of the door and a decrease in the appearance quality.

[0014] The present invention was devised in consideration of the technical problems with the conventional glass runs, and one of its objects is to provide a glass run mounting structure that can prevent the molding lip from falling off due to accidental detachment caused by vehicle vibration or its own weight, by using the strong holding force of the flange on the inside of the door inner panel against the molding lip. [Means for solving the problem]

[0015] The invention described in claim 1 of the present application is a mounting structure for a glass run comprising: a bottom wall; an interior side wall and an exterior side wall provided at both end edges of the bottom wall in the width direction; a plurality of retaining lips provided on opposing inner surfaces of the interior side wall and the exterior side wall, each of which abuts against and holds both sides of a door glass; an extension wall provided at an end of the interior side wall opposite the bottom wall; and an interior molding lip provided in a folded shape at a tip end of the extension wall, which jointly forms a fitting groove between the interior side wall and the extension wall, wherein the fitting groove is fitted into an interior flange provided at an end of an interior panel that forms a sash portion of a door, and the molding lip is attached and held therein, An engaging portion is formed at the tip of the flange on the inside of the vehicle, while a locking portion is provided on the inner surface of the extension wall to lock onto the engaging portion from the vertical direction of the vehicle body and hold the molding lip. [Effects of the Invention]

[0016] According to the invention described in claim 1, a strong holding force for the molding lip can be obtained by engaging the engagement portion formed on the flange of the inner panel of the sash with the locking portion provided on the glass run. This prevents the molding lip from accidentally falling off due to vibrations or the vehicle's own weight. As a result, it is possible to prevent deterioration in the appearance of the door sash and prevent a decrease in appearance quality. [Brief explanation of the drawings]

[0018] Hereinafter, an embodiment of the glass run mounting structure according to the present invention will be described in detail with reference to the drawings. In this embodiment, a glass run is mounted on the sash portion of a front door of a pressed door type automobile.

[0019] 2 is a cross-sectional view taken along line AA in FIG. 1, showing the mounting structure of the glass run of the first embodiment; FIG. 3 is an enlarged view of the main part of the mounting structure of the glass run shown in FIG. 2; and FIG. 4 is a cross-sectional view showing the deflection and deformation state when the locking protrusion used in this embodiment is locked to the inner flange.

[0020] As shown in Fig. 1, the front door 2 of an automobile 1 is provided with a sash portion 4 integral with the door main body 2a at the upper end of the door main body 2a. As shown in Fig. 2, this sash portion 4 is composed of an outer panel 8 and an inner panel 9 of the door, and the outer panel 8 has an outer wall 8a as a molding portion at a position facing the outside of the vehicle.

[0021] Meanwhile, the inner panel 9 is formed of a first vehicle interior panel 9a and a second vehicle interior panel 9b having a double inner and outer structure whose upper and lower ends are joined by spot welding or the like, and as will be described later, the upper end of the second vehicle interior panel 9b is joined to the outer panel 8 by a rivet 17. Furthermore, a reinforcement bracket (retainer) 18 is formed by the various portions of the outer panel 8 and inner panel 9 joined by this rivet 17, and a long glass run 21 having a substantially U-shaped cross section is attached in a fitted state to the inner periphery of this retainer 18.

[0022] The outer panel 8 has a lower end 8b of an outer wall 8a bent toward the interior of the vehicle so as to have a substantially U-shaped cross section, and supports a vehicle-exterior side wall 23 of the glass run 21, which will be described later.

[0023] The inner panel 9 has a second interior panel 9b that bulges out in a horizontal U-shape toward the interior of the vehicle, and an upper end 9e of the second interior panel 9b in the drawing is joined to the outer panel 8 by a rivet 17 and also forms part of a retainer 18. A lower flange 9f of the second interior panel 9b extends downward and forms part of the interior flange.

[0024] The first interior panel 9a has an upper end 9g joined to the underside of the upper end 9e of the second interior panel 9b by welding, and a lower flange 9h at the lower end joined to the lower flange 9f of the second interior panel 9b by welding, thereby forming part of the interior flange.

[0025] The lower flange 9h has a tip portion bent into an approximately L-shaped cross section toward the vehicle interior side wall 24 (toward the vehicle exterior) of the glass run 21, and this L-shaped bent lower flange 9h is configured as an engagement portion.

[0026] Furthermore, the first interior panel 9a is deformed by swelling outward toward the interior of the vehicle at the lower part of the upper end 9g, and a retaining recess 9i is formed inside this.

[0027] The glass run 21 is formed as a continuous, integral piece by extrusion molding, and as shown in FIG. 2, includes a bottom wall 22 arranged on the underside of the retainer 18, and an exterior side wall 23 and an interior side wall 24 joined to both end edges of the bottom wall 22 and extending substantially perpendicularly from the end edges.

[0028] 2, the bottom wall 22 has a base formed of a soft material, foamed thermoplastic vulcanized rubber (TPV), and is provided on its underside with a contact lip 25 that extends toward the vehicle-exterior side wall 23 and elastically contacts and seals the leading edge of the door glass 10 when the door glass 10 is in the raised position. A first seal lip 26 is provided on the outer surface of one widthwise end of the bottom wall 22 and elastically contacts the outer wall 8a of the outer panel 8 from the inside, while a second seal lip 27 is provided on the outer surface of the other widthwise end and elastically contacts and supports the inner surface of a retaining recess 9i at the upper end of the first vehicle-interior panel 9a of the inner panel 9. The contact lip 25, first seal lip 26, and second seal lip 27 are each formed of a hard material, TPV, and have sealing and soundproofing functions, thereby ensuring watertightness and blocking wind noise.

[0029] 2, the exterior side wall 23 has a base formed from foamed TPV, which is the same soft material as the bottom wall 22, and is thinner than the interior side wall 24, with a fitting recess 23a formed on its outer surface into which the lower end of the outer wall 8a of the outer panel 8 fits. In addition, the exterior side wall 23 is provided at its lower end opposite the bottom wall 22 with a first retaining lip 28 that is inclined toward the interior side wall 24 and abuts against the exterior side surface of the door glass 10 while guiding it to slide. This first retaining lip 28 is formed from TPV, a hard material.

[0030] The interior side wall 24, like the bottom wall 22, is made of a soft foamed TPV material and is thicker than the exterior side wall 23. The interior side wall 24 extends in the vertical direction of the vehicle body. A support lip 29 is provided near the second seal lip 27 of the bottom wall 22, similarly elastically supporting the inner surface of the retaining recess 9i of the first interior panel 9a. The interior side wall 24 also has a second retaining lip 30 inclined toward the bottom wall 22 at its lower end opposite the bottom wall 22. The second retaining lip 30 abuts against and guides the exterior side surface of the door glass 10. The second retaining lip 30 is thicker than the first retaining lip 28 and extends from its lower end toward the first retaining lip 28. Therefore, the door glass 10 is sandwiched between the first retaining lip 28 and the second retaining lip 30, allowing it to slide stably. The support lip 29 and the second retaining lip 30 are made of a hard TPV material.

[0031] Furthermore, a reaction force applying lip 31 is provided on the inner surface of the interior side wall 24 at a position facing the first retaining lip 28, and is inclined toward the exterior side wall 23. This reaction force applying lip 31 is made of the same hard TPV material as the second retaining lip 30, and is configured to apply a reaction force by coming into contact with the back surface of the upper end of the second retaining lip 30 when the door glass 10 rises and the second retaining lip 30 falls and deforms toward the interior side wall 24. This makes it possible to prevent unnecessary displacement of the door glass 10 toward the interior of the vehicle while the vehicle is moving.

[0032] An extension wall 32 is integrally formed at the lower end of the interior side wall 24, and an interior molding lip 33 is provided continuously with the tip of this extension wall 32. As shown in Fig. 2, the extension wall 32 is formed in a substantially flat plate shape, with a base portion formed from the same soft foamed TPV material as the interior side wall 24, and a lower portion in the figure formed from a hard TPV material. The extension wall 32 has a curved base portion 32a joined to the lower end of the interior side wall 24, and a substantially flat support portion 32b extending from the base portion 32a toward the molding lip 33.

[0033] The molding lip 33 has a base portion formed of the same soft foamed TPV as the extension wall 32, and an outer portion formed of the hard TPV, and is formed by folding back from the tip of the support portion 32b toward the upper side of the vehicle body, to jointly form a fitting groove 34 between the extension wall 32 and the interior side wall 24. The lower flanges 9f, 9h of the first interior panel 9a and the second interior panel 9b are fitted into this fitting groove 34, and in this fitted state, the molding lip 33 conceals the lower flanges 9f, 9h.

[0034] The extension wall 32 is integrally provided with a hook-shaped locking projection 35, which is a locking portion that locks onto the lower flange 9h of the first interior panel 9a, on the upper surface of the support portion 32b. The entire locking projection 35 is made of the soft foamed TPV material, like the base portion of the extension wall 32, and is disposed facing the fitting groove 34. The locking projection 35 has a base end 35a that extends upward in a substantially straight line from the upper surface of the support portion 32b, and a tip hook portion 35b that is bent in an inverted U-shape from the tip of the base end 35a toward the support portion 32b.

[0035] 3, base end 35a is formed to have a relatively large thickness and a substantially uniform thickness width W in the vertical direction to ensure rigidity. On the other hand, tip hook portion 35b is formed to gradually taper slightly from the joint with base end 35a to tip end 35c, with thickness width W1 set to about 1 / 2 or less of the thickness width W of base end 35a, allowing it to flex and deform inward mainly around the joint with base end 35a.

[0036] Therefore, when the extension wall 32 is lifted upward to attach the glass run 21 to the retainer 18 side from below, the tip hook portion 35b of the locking projection 35 moves upward while bending inward as the outer surface of the tip hook portion 35b abuts against the tip edge 9j of the lower flange 9h, as shown by the two-dot chain line in Figure 4. After that, when the tip hook portion 35b passes the tip edge 9j, it returns to its original shape and the tip portion 35c abuts against the upper surface of the lower flange 9h and is locked.

[0037] [Function and effect of the glass run mounting structure according to this embodiment] As described above, when attaching the glass run 21 to the retainer 18 from below, the extension wall 32 is lifted upward together with the molding lip 33, so that the tip hook portion 35b of the locking protrusion 35 abuts against the upper surface of the lower flange 9h of the first interior panel 9a and locks in place.

[0038] Therefore, the molding lip 33 is firmly held in place by the locking force of the locking projection 35 against the lower flange 9h. This prevents the molding lip 33 from accidentally dropping or falling off due to vibrations of the vehicle body or its own weight, thereby preventing a decrease in the appearance quality of the door.

[0039] In particular, since the lower flange 9h of the first interior panel 9a is formed to have a substantially L-shaped cross section, the locking force between the upper surface of the lower flange 9h and the tip hook portion 35b of the locking projection 35, whose tip portion 35c is locked to the upper surface of the lower flange 9h, is increased, thereby providing a stable holding force for the molding lip 33.

[0040] Furthermore, the glass run 21 is held in place not only by the engagement between the lower flange 9h of the first interior panel 9a and the locking projection 35, but also by the elastic engagement of the tip of the support lip 29 with the inner surface of a retaining recess 9i formed on the upper side of the first interior panel 9a. In other words, the glass run 21 is doubly held to the first interior panel 9a at two locations, above and below. Therefore, the entire glass run 21 is securely and stably held to the inner panel 9, which effectively prevents the glass run 21 itself from accidentally falling off due to vibration of the vehicle body, its own weight, or the like.

[0041] Furthermore, in this embodiment, flexibility is ensured by being formed with a thickness sufficiently thinner than that of the base end portion 35a of the locking projection 35. Therefore, as described above, when the glass run 21 is attached to the sash portion 4, the tip hook portion 35b is pressed by the tip edge 9j of the lower flange 9h and is relatively easily bent and deformed inward. This improves the insertability of the tip hook portion 35b and makes it easier to attach the entire glass run 21, including the molding lip 33.

[0042] On the other hand, since the base end 35a of the locking projection 35 has a relatively high rigidity, when the tip hook portion 35b locks onto the lower flange 9h, the rigidity of the base end 35a supports the tip hook portion 35b, thereby increasing the locking force between the tip hook portion 35b and the lower flange 9h, and enabling the glass run 21 (mold lip 33) to be held stably and firmly.

[0043] Second Embodiment FIG. 5 is a cross-sectional view of line AA in FIG. 1 showing the mounting structure of a glass run according to a second embodiment of the present invention, and FIG. 6 is a cross-sectional view showing the deflection and deformation state when the locking protrusion used in this embodiment is locked to the interior flange.

[0044] Figure 5 shows a second embodiment of the glass run mounting structure according to the present invention. The basic configuration of the glass run 21 is the same as that of the first embodiment, but a first notch portion 36 is provided at the base of the base end portion 35a of the locking protrusion 35, and a second notch portion 37 is provided on the inside of one end portion in the width direction of the extension wall 32.

[0045] Therefore, according to the second embodiment, when the extension wall 32 is lifted upward to attach the glass run 21 to the retainer 18 from below, the outer surface of the tip hook portion 35b of the locking projection 35 is pressed against the tip edge 9j of the lower flange 9h. Then, as shown by the two-dot chain line in Fig. 6 , the tip hook portion 35b of the locking projection 35 is flexibly deformed inward by the reaction force, and the locking projection 35 easily falls to the right in the drawing (toward the interior side wall 24) via the first notch portion 36, and the extension wall 32 also easily falls toward the interior side wall 24 via the second notch portion 37. Therefore, when attaching the glass run 21, the locking projection 35 and the extension wall 32 do not impart insertion resistance, and smooth insertion is achieved, further improving the ease of attaching the glass run 21.

[0046] In particular, if there is variation in the protruding length of the tip of the flange 9h on the vehicle interior side, which is the engaging part, due to manufacturing errors or dimensional errors in the inner panel 9 of the sash portion 4, and it extends slightly in the direction of the extension wall 32, when the glass run 21 is installed, the locking projection 35 and the extension wall 32 will flex and deform via the first and second notch portions 36, 37 to absorb the variation, making the insertion work easier and, as a result, further suppressing deterioration in the ease of installing the glass run 21.

[0047] In this embodiment, two notches, the first and second notches 36 and 37, are provided, but it is also possible to provide only one of the first notch 36 or the second notch 37. Also, it is possible to provide a notch at any position on the upper surface of the extension wall 32, that is, between the base of the base end 35a of the locking projection 35 and the inside of one end of the extension wall 32 in the width direction.

[0048] Third Embodiment FIG. 7 shows a third embodiment of the glass run mounting structure according to the present invention. The basic configuration of the invention is the same as that of the first and second embodiments, but the structure of the outer panel and inner panel of the sash section and the structure of the glass run have been slightly modified.

[0049] The outer panel 8 is configured to cover from above the bottom wall 22, the vehicle exterior side wall 23, and the vehicle interior side wall 24 of the glass run 21. In other words, the outer wall 8a is folded back to form a hemmed shape and is arranged to cover the entire exterior side wall 23 of the glass run 21, including the fitting recess 23a, and the upper end 8c is arranged to cover the entire upper surface of the bottom wall 22.

[0050] The outer panel 8 is disposed such that the inner wall 8d covers the outer surface of the interior side wall 24, and the tips of the first and second support lips 27, 29 of the glass run 21 are in elastic contact with the inner surface of a retaining recess 8e formed at the upper end of the inner wall 8d. Furthermore, a first protrusion 38 and a second protrusion 39 provided on the outer surface of the interior side wall 24 of the glass run 21 abut and engage with the inner surface of the inner wall 8d. The first protrusion 38 is formed of a soft foamed TPV, like the interior side wall 24, while the second protrusion 39 is formed of a hard TPV. The lower end 8f of the inner wall 8d is bent in an L-shape in cross section toward the interior side wall 24, and the second protrusion 39 abuts and engages with this lower end surface to securely hold the glass run 21.

[0051] The inner panel 9 has a double structure of a first vehicle-interior panel 9a and a second vehicle-interior panel 9b, as in the first embodiment, but an upper end 9g of the first vehicle-interior panel 9a extends substantially horizontally above the outer panel 8. In addition, a lower flange 9h formed in an L-shaped cross section is provided at the lower end of this first vehicle-interior panel 9a.

[0052] In the glass run 21, the second retaining lip 30 on the interior side wall 24 is shorter than that in the previous embodiments, and the reaction force applying lip is eliminated, with a third retaining lip 40 provided above the second retaining lip 30. The third retaining lip 40, together with the second retaining lip 30, guides the sliding of one side surface of the door glass 10 on the interior side of the vehicle.

[0053] The configurations of the extension wall 32 provided at the lower end of the interior side wall 24 and the locking projection 35 provided on the upper surface of the extension wall 32 and locking with the lower flange 9h are the same as those in the first embodiment.

[0054] Therefore, according to this embodiment, the same effects as those of the first embodiment are achieved, but in particular, the glass run 21 is held in place in its entirety by the outer panel 8 in a fitted state, and the first and second protrusions 38, 39 are engaged while abutting against the inner surface of the inner wall 8d of the outer panel 8, so that it is held even more stably and securely.

[0055] The present invention is not limited to the above-described embodiment, and for example, the cross-sectional shape of the glass run 21, the length of the outer side wall 23 and the inner side wall 24, and the cross-sectional shape of the bottom wall 22 can be changed as desired depending on the shape and size of the vehicle body.

[0056] In addition, in each of the above embodiments, the lower flange 9h is formed in an L-shape as the engaging portion, but the lower flange 9h may also be formed, for example, with a V-shaped cross section. Also, as the engaging portion, a protrusion or the like that can engage with the locking protrusion 35 may be provided on the upper surface of the lower flange 9h.

[0057] Furthermore, the lower flange portion 9h may be formed in various shapes, for example, in a hemmed shape, or may be formed intermittently by cutting out predetermined portions in the longitudinal direction.

[0058] Furthermore, it goes without saying that the glass run mounting structure of the present invention can be applied to the sash portion 5 of the rear door 3 in addition to the front door 2. [Explanation of symbols]
