Japanese Patent Laid-Open No. 2003-252055

  However, since the weatherstrip mounting structure disclosed in Patent Document 1 is a structure in which the weatherstrip is firmly press-fitted to the door trim, a strong pressure input or pull-out force is applied when the weatherstrip is assembled or replaced. Therefore, there is a problem that it is difficult to manually assemble and replace. Of course, if the press-fitting allowance of the weather strip is set small, it is possible to easily assemble and replace the weather strip. However, in this case, the weather strip support strength cannot be sufficiently obtained. Therefore, it becomes difficult to withstand the repeated raising and lowering operation of the door glass.

  The present invention has been made in view of the above-described problems, and is capable of easily assembling and replacing the weather strip and mounting the weather strip capable of reliably obtaining the necessary support strength. The purpose is to provide a structure.

  In order to solve the above problems, the present invention is attached to a door trim that covers the inner side surface of the inner panel in order to seal the inner side surface of the door glass that moves up and down between the outer panel and the inner panel of the automobile door. A weather strip mounting structure, wherein the door trim extends in a vertical direction to cover an inner side surface of the inner panel, and an upper surface plate extends from the upper side of the side plate to the outer side of the vehicle and covers the upper side of the inner panel. A trim body, and a rib that is provided on the back surface of the trim body and projects outwardly between the upper surface plate and the upper end of the inner panel, and the weather strip is disposed outside the vehicle of the inner panel. A base portion installed in the vertical direction along the side surface, and a front end portion protruding from the base portion toward the outside of the vehicle, A lip portion that comes into contact with the first mounting piece that protrudes inward from the base portion and is inserted between the top plate of the door trim and the rib; and the rib that is arranged below the first mounting piece in parallel. And a second mounting piece projecting in the vehicle interior direction along the lower surface of the second mounting piece, and the second mounting piece is provided with an engaged portion with which the upper end of the inner panel is engaged. (Claim 1).

  According to this weather strip mounting structure, the upper end of the inner panel is engaged with the engaged portion provided in the second mounting piece of the weather strip, so that the weather strip is effectively removed from the door trim. The weather strip will be attached in a prevented state. Further, the first mounting piece of the weather strip is inserted between the upper surface plate of the door trim and the rib to sandwich the upper and lower surfaces of the first mounting piece, and the second mounting piece is arranged along the lower surface of the rib. Thus, when a downward force is applied to the lip portion of the weather strip as the door glass is lowered, the first mounting piece and the second mounting piece start from the base end portion according to the bending moment generated thereby. It is possible to suppress deformation so as to warp. As a result, it is possible to prevent the second mounting piece and the inner panel from being disengaged with the deformation, and to enhance the effect of preventing the weather strip from falling off. On the other hand, if the door trim is removed from the inner panel in this state, the engagement between the second mounting piece of the weather strip and the inner panel can be released, so that the weather strip can be easily assembled and replaced with the door trim. Can do.

  In the above configuration, the upper surface plate of the door trim is provided with a protruding portion that protrudes downward, and the first mounting piece of the weather strip is provided with an engaged portion with which the protruding portion is engaged. (Claim 2).

  In this way, the first mounting piece of the weather strip is also provided with the engaged portion, and the protruding portion provided on the upper surface plate of the door trim is engaged with the engaged portion, whereby the first mounting piece and the above-mentioned Since two places with the 2nd attachment piece latched by an inner panel can be latched, falling-off of a weather strip can be prevented more certainly. Further, even when the engagement portion is provided on the first mounting piece in this manner, if the projection height of the projection portion of the door trim engaged with the first attachment piece is not set higher than necessary, the assembly / While ensuring the ease of replacement, it is possible to increase the weather stripping prevention effect.

  The door trim includes a first rib (corresponding to the “rib”) that is provided on the rear surface of the trim body and protrudes outwardly between the upper surface plate and the upper end portion of the inner panel. A second rib arranged in parallel below the rib and having a front end abutting against an inner surface of the inner panel, and the second mounting piece of the weather strip is inserted between the first and second ribs of the door trim. It is preferable to be locked (claim 3).

  As described above, the second rib is provided below the first rib corresponding to the “rib”, and the front end of the second rib abuts against the inner side surface of the inner panel when the door trim is assembled. Since the assembling position can be determined when assembling the door trim, it is possible to improve the assembling accuracy of the door trim and the assembling accuracy of the weather strip attached thereto. Further, by inserting the second mounting piece of the weather strip between the first and second ribs and sandwiching the upper and lower surfaces of the second mounting piece, the mounting posture of the weather strip can be further stabilized. Therefore, the weather strip can be more effectively prevented from falling off.

  In this case, it is preferable that the thickness of the second mounting piece of the weather strip is set to a value larger than the gap between the first and second ribs of the door trim.

  In this case, since the second mounting piece of the weather strip is press-fitted between the first and second ribs of the door trim, the support strength of the second mounting piece can be increased, and the weather strip can be more reliably detached. Can be prevented. In this case, in addition to preventing the weather strip from falling off due to the engagement of the second mounting piece (or both the first and second mounting pieces) as described above, prevention of falling off by press-fitting (enhancement of support strength) is made. However, if the allowance for press-fitting the second mounting piece is not set to be larger than necessary, the effect of preventing the weather strip from dropping can be enhanced without significantly impairing the ease of assembly and replacement of the weather strip. In addition, since the second mounting piece of the weather strip is press-fitted between the first and second ribs of the door trim, the press-fitted second mounting piece tends to push up the first rib. There is also an advantage that the first mounting piece of the weather strip inserted between the first rib and the upper surface plate receives a compressive force in the vertical direction, and the support strength of the first mounting piece is increased.

  As described above, according to the weather strip mounting structure of the present invention, it is possible to easily assemble and replace the weather strip, and to surely obtain the necessary support strength.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view of an automobile door in which the weather strip according to the present embodiment is adopted, and FIG. 2 is a cross-sectional view taken along the line II in FIG. 1 and shows a weather strip mounting structure according to the present embodiment. It is. As shown in FIGS. 1 and 2, the automobile door 1 includes a door body 3 including an outer panel 32 and an inner panel 34, and a door glass 5 that moves up and down between the outer panel 32 and the inner panel 34. ing. A door trim 36 is attached to the inner panel 34 so as to cover the inner side surface of the vehicle, and a weather strip 10 for sealing a gap between the inner panel 34 and the door glass 5 is provided above the door trim 36. It is attached. The outer weather strip 20 is also attached to the outer panel 32. Hereinafter, the mounting structure of the weather strip 10 provided inside the vehicle will be described in detail.

  The door trim 36 includes a side plate 42 that extends in the vertical direction so as to cover the inner side surface of the inner panel 34, and an upper surface plate 44 that bends from the upper part of the side plate 42 toward the outer side of the vehicle and covers the inner panel 34. The first rib 46 and the second rib 48 are arranged on the back surface of the trim body 40 in a vertical direction at a predetermined interval. A downward projecting portion 44 a that is engaged with a first mounting piece 14 of a weather strip 10 described later is provided at the outer edge of the upper surface plate 44.

  The first rib 46 is installed at a height such that it protrudes outwardly from the upper surface plate 44 and the upper end 34 a of the inner panel 34. Further, the second rib 48 has such a length that its tip end comes into contact with the inner surface of the inner panel 34.

  The weather strip 10 is made of an elastic body such as synthetic rubber, and has a base portion 12 installed in the vertical direction along the vehicle outer surface of the inner panel 34, and a door glass projecting from the base portion 12 in the vehicle outward direction. 5 and two first lip portions 18 that are in contact with the front end portion of the door trim 36 and inserted between the top plate 44 and the first rib 46 of the door trim 36. And a second mounting piece 16 that is juxtaposed below the first mounting piece 14 and is inserted between the first and second ribs 46 and 48 of the door trim 36.

  An engagement step 14a with which the protrusion 44a of the door trim 36 is engaged is provided on the upper surface (vehicle outer corner) of the first mounting piece 14, and the lower surface of the second mounting piece 16 is provided. Is provided with an engaging recess 16a with which the upper end 34a of the inner panel 34 is engaged.

  As described above, the protruding portion 44 a of the door trim 44 engages with the engaging step portion 14 a of the first mounting piece 14, and the upper end portion 34 a of the inner panel 34 engages with the engaging concave portion 16 a of the second mounting piece 16. Thus, the weather strip 10 is stably fixed to the door trim 44.

  Next, a procedure for assembling the weather strip 10 having the above structure to the door trim 36 will be described with reference to FIG.

  First, the weather strip 10 is assembled to the door trim 36 before being attached to the inner panel 34 (arrow A in the figure). Specifically, the first mounting piece 14 of the weather strip 10 is inserted between the top plate 44 of the door trim 36 and the first rib 46, and the second mounting piece 16 is inserted into the first and second ribs 46 of the door trim 36. , 48. At this time, in order to engage the protruding portion 44a of the door trim 36 with the engaging step portion 14a of the first mounting piece 14, the thickened portion of the first mounting piece 14 (thickness forming the inner side surface of the engaging step portion 14a). It is necessary to elastically deform the portion having a large thickness) so that the protruding portion 44a gets over the thickened portion. That is, in order to insert the first attachment piece 14 between the upper surface plate 44 and the first rib 46, it is necessary to apply a certain pushing force. On the other hand, it is not necessary to give such pushing force when inserting the second mounting piece 16. That is, there is nothing that obstructs the insertion of the second mounting piece 16 in the state before the door trim 36 is assembled to the inner panel 34. Therefore, the second mounting piece 16 is smoothly connected between the first and second ribs 46, 48. Can be inserted into. Thus, when the weather strip 10 is assembled to the door trim 36 in a state before being attached to the inner panel 34, only the first mounting piece 14 needs to be elastically deformed. In addition, the weather strip 10 can be easily assembled to the door trim 36.

  Next, the door trim 36 with the weather strip 10 mounted thereon is assembled to the inner panel 34 (arrow B in the figure). As a result, the upper end portion 34a of the inner panel 34 protrudes above the second rib 48 of the door trim 36, and the engagement between the upper end portion 34a and the engagement recess 16a of the second mounting piece 16 is completed ( The state of FIG. Thereby, since the two places of the said 2nd attachment piece 16 and the 1st attachment piece 14 latched by the said door trim 36 (projecting part 44a) can be latched, the support strength of the weather strip 10 is further increased. Can be improved. At this time, the tip of the second rib 48 of the door trim 36 is brought into contact with the inner side surface of the inner panel 34 so that positioning is performed when the door trim 36 is assembled. The assembling accuracy of the weather strip 10 can be improved.

  When it is necessary to replace the weather strip 10 after the weather strip 10 has been assembled as described above, for example, during maintenance of the automobile, the replacement work can be performed by following the procedure reverse to the above procedure. Can be performed smoothly. That is, first, the door trim 36 is removed from the inner panel 34, the engagement between the second mounting piece 16 of the weather strip 10 and the inner panel 34 is released, and then the weather strip 10 is removed and reattached. The weather strip 10 can be easily replaced.

  As described above, according to the weather strip 10 mounting structure of the present embodiment, the protrusion 44a of the door trim 36 is engaged with the engaging step 14a provided on the first mounting piece 14 of the weather strip 10. At the same time, the upper end 34a of the inner panel 34 is engaged with the engaging recess 16a provided in the second mounting piece 16 of the weather strip 10, so that the weather strip 10 is effectively prevented from falling off the door trim 36. In this state, the weather strip 10 is attached. Further, the first mounting piece 14 of the weather strip 10 is inserted between the top plate 44 of the door trim 36 and the first rib 46, and the second mounting piece 16 is inserted between the first and second ribs 46 and 48 of the door trim 36. , And thereby the upper and lower surfaces of the first and second mounting pieces 14 and 16 are sandwiched, respectively, and a downward force is applied to the lip portion 18 of the weather strip 10 as the door glass 5 is lowered. It is possible to prevent the first mounting piece 14 and the second mounting piece 16 from being deformed so as to warp from the base end portion according to the bending moment generated thereby. As a result, it is possible to prevent the first mounting piece 14 and the second mounting piece 16 from being disengaged with the deformation, and thus the effect of preventing the weather strip 10 from falling off can be enhanced. On the other hand, if the door trim 36 is removed from the inner panel 34 in this state, the engagement between the second mounting piece 16 of the weather strip 10 and the inner panel 34 can be released. Exchange work can be performed easily.

  The weather strip 10 mounting structure described above is an example of a weather strip mounting structure according to the present invention, and the specific configuration thereof can be appropriately changed without departing from the gist of the present invention. A modification will be described below.

  (1) In the above embodiment, the thickness of the first mounting piece 14 and the second mounting piece 16 of the weather strip 10 is not particularly mentioned, but for example, the thickness of the second mounting piece 16 (the thickest part). Is preferably set to a thickness that is thicker than the gap between the first and second ribs 46 and 48 of the door trim 36 into which the door trim 36 is inserted. In this way, since the second mounting piece 16 of the weather strip 10 is press-fitted between the first and second ribs 46 and 48, the support strength of the second mounting piece 16 can be increased, and the weather strip Dropout can be prevented more reliably. In this case, since the weather strip 10 is already prevented from falling off due to the engagement of the first and second mounting pieces 14 and 16 as described above, the press-fitting allowance of the second mounting piece 16 is not set larger than necessary. It is preferable. Thereby, the fall-off prevention effect of the weather strip 10 can be enhanced without greatly impairing the ease of assembly and replacement of the weather strip 10. Further, when the second mounting piece 16 of the weather strip 10 is press-fitted between the first and second ribs 46 and 48 of the door trim 36, the press-fitted second mounting piece 16 moves up the first rib 46. The first mounting piece 14 inserted between the first rib 46 and the upper surface plate 44 receives a compressive force in the vertical direction, and the support strength of the first mounting piece 14 is increased. There are also advantages.

  (2) In the above-described embodiment, the example in which the second rib 48 is also provided below the first rib 46 provided on the back surface of the door trim 36 has been described. However, as shown in FIG. 48 may be omitted. In the door trim 136 according to the example of FIG. 4, since the second rib 48 shown in FIG. 2 is omitted, the door trim 136 can be easily formed, and the manufacturing cost of the door trim 136 can be reduced. Of course, unlike the above embodiment, the upper and lower surfaces of the second mounting piece 16 of the weather strip 10 are not sandwiched between the first and second ribs 46 and 48, so the stability of the mounting posture of the weather strip 100 is reduced. Even in such a case, the first rib 46 existing on the upper surface of the second mounting piece 16 is deformed so that the second mounting piece 16 is warped from its base end according to the bending moment generated when the door glass 5 is lowered. Therefore, it is possible to prevent the second mounting piece 16 and the inner panel 34 from being disengaged with the deformation.

  (3) In the above embodiment, the engaging recess 16 a provided in the second mounting piece 16 of the weather strip 10 is engaged with the upper end portion 34 a of the inner panel 34 and the engaging step portion 14 a of the first mounting piece 14. Is engaged with the protruding portion 44a of the door trim 36, but the engagement step portion 14a of the first mounting piece 14 may be omitted, and an example is shown in FIG. In the weather strip 100 according to the example of FIG. 5, the engagement step 14 a shown in FIG. 2 is omitted, and the protrusion 44 a shown in FIG. 2 is omitted in the door trim 236. . In this way, the assembly and replacement of the weather strip 100 can be further facilitated. Of course, unlike the above-described embodiment, since there is nothing that restricts the horizontal movement of the first mounting piece 114, the support strength of the weather strip 100 is reduced, but even in that case, the second mounting piece 16 and the inner panel 34 are not connected. Since it is still engaged, the effect of preventing the weather strip 100 from falling off can be ensured at a necessary level. However, when emphasizing the support strength of the weather strip 100, the engagement step 14a is provided on the first mounting piece 14 and the protrusion 44a is provided on the door trim 36, as in the above-described embodiment. It is preferable to engage the portion 14a and the protruding portion 44a. Even if it does in this way, if the protrusion height of the protrusion part 44a is not set higher than necessary, the fall prevention effect of the weather strip 10 will be enhanced while securing the ease of assembly and replacement of the weather strip 10 to some extent. Can do.
