Description

  The present invention relates to a weather strip mounting structure in an automobile, and more particularly to a structure in which a molded part of a weather strip having a molded part continuous with a general part is fixed to a predetermined panel with a clip.

  As this type of weather strip mounting structure, those described in Patent Document 1 and Patent Document 2 have been proposed.

  In those described in Patent Documents 1 and 2, a uniform cross-sectional shape is formed at a corner portion formed by a roof side upper side portion and a pillar side vertical side portion of a door weather strip mounted on a peripheral portion of a door panel including a door sash. Since a molding part (mold molding part) that connects so-called general parts (extrusion molding parts) that are extruded to each other is set, the part of the mold molding part that is not directly involved in the seal is relatively large A clip having a pressure contact restraint surface is pressed and held on the panel forming the door sash.

Japanese Patent No. 37768853 Japanese Patent No. 3890565

  However, in the conventional structure as described in Patent Documents 1 and 2, there is a relatively large difference in level (step) in the counterpart panel where the molded part is located, but the panel is formed by a clip. The shape of the molded part that is pressed and held between the two is not that which closely follows the shape of the counterpart panel, and is relatively thick to absorb the difference in height of the panel It has a shape. Then, the anchor portion of the clip that is to be locked to the panel is set to the relatively thin portion of the molded portion, and the thickness of the molded portion is set at the tip of the clip that is relatively far from the anchor portion. Since the meat part is pressed down, not only does the weight of the molding part increase, but the binding force of the thick part due to the clip is insufficient, and the thick part floats together with the tip of the clip. Due to the decrease in the attaching accuracy, it becomes easy to cause the sealing performance failure of the seal portion set in the mold forming portion and the increase of the door closing force. In addition, the tip of the clip far from the anchor portion is constantly subjected to a reaction force from the thick portion of the molded portion, so that the clip may come off when it changes over time or when the door is suddenly closed.

  The present invention has been made paying attention to such problems, and the mold-formed part is securely brought into close contact with the panel to prevent the occurrence of secondary problems due to a decrease in the assembly accuracy as described above. Accordingly, the present invention provides a mounting structure that prevents the clip from coming off when the door is aged or when the door is suddenly closed.

  The invention according to claim 1 is a structure in which the mold forming portion of the weather strip having a mold forming portion continuous with the general portion is fixed to the panel with a clip, and the higher side of the seating surface having a height difference among the panels. In addition, the mold part is arranged so as to straddle both the lower side and the mold part is fixed to the seating surface with a clip that is fitted into an attachment hole formed in both the seating surface and the mold part. is there.

  And while forming the said mold part as a substantially plate-like thing approximated to the seating surface shape with a height difference, the said clip is superposed on the mold part, and the high side of the said mold part and It has a substantially plate-like main body seated on both the lower side and an anchor portion protruding from a portion of the main body seated on the higher side of the mold forming portion.

  Then, in the portion other than the portion seated on the higher side of the molded part of the main body part of the clip, the shape is a smoothly curved shape so as to ensure a gap between the molded part, In the portion corresponding to the gap, a rib having a partition shape approximating the cross-sectional shape of the gap is formed from either one of the molded part and the main body of the clip so as to be in contact with the other. is there.

  The weather strip here refers to a door parting seal that is mounted along the inner surface of the front end portion of the door panel of an automobile and seals between the front end edge of the door panel and the end edge of a member facing the door panel. The door weather strip etc. with which the peripheral part of a sash is mounted are assumed.

  In this case, the partition rib may be a single rib, but a plurality of the ribs are formed at a predetermined pitch according to claim 2, depending on the size of the gap. It is desirable to do.

  Further, as described in claim 3, partition-shaped ribs are formed so as to protrude from both the mold forming portion and the clip main body, and the ribs are polymerized while being in contact with each other. If at least one of the rib and the rib of the main body of the clip is set so as to bottom out to the other, it becomes more advantageous in making relative positioning and detent of both more reliable.

  Furthermore, in order to more reliably prevent the tip of the clip from lifting in the main body of the clip, as described in claim 4, the tip of the main body of the clip is placed on the lower portion of the molded part. It is desirable to form a bag-like locking groove that is locked while seated.

  According to a fifth aspect of the present invention, on the premise of the weather strip mounting structure according to the fourth aspect, the weather strip is mounted along the inner surface of the front end of the door panel of the automobile, and the front end of the door panel is mounted. A door parting seal that seals between an edge and an edge of a member that faces the edge, and a seating surface of the panel on which the molded part is mounted forms a door panel together with the door outer panel. It is clarified that it is the surface of the panel on the vehicle interior side, and that the molded part is integrally formed as a wide terminal part at the lower end of the general part of the door parting seal.

  According to a sixth aspect of the invention, on the premise of the weather strip mounting structure of the fourth aspect, the general part of the door parting seal is fitted and held in the hemming joint at the front end of the door panel. While having a letter-shaped welt part and a seal lip having a substantially arc-shaped cross section of a cantilever support structure extending from the welt part, it is integrally formed as a wide terminal part at the lower end of the general part. The mold forming part is characterized in that the welt part has disappeared and a seal lip continuous with the seal lip on the general part side is integrally formed.

  In this case, in order to improve the relative positioning accuracy and appearance of the molded part and the clip, as shown in claim 7, a bag-like locking groove is formed around the molded part. It is desirable that an edge rib is continuously formed on the wall portion, and the main body portion of the clip is disposed so as to be inscribed in the edge rib including the wall portion.

  Further, when focusing on the improvement of the appearance as described above, it is desirable that at least the main body of the clip has the same color as that of the door parting seal.

  For the same reason, as described in claim 9, when a side sill parting seal that seals between the lower end edge of the door panel and the side sill is provided along the inner surface of the lower end of the door panel, The molded part of the door parting seal preferably receives and holds the upper end of the side sill parting seal inside thereof.

  Therefore, in at least the invention described in claim 1, at the portion corresponding to the gap portion, the rib is formed in a protruding manner from the mold forming portion or the main body portion side of the clip without being thickened as a whole. Therefore, the weight can be reduced by reducing the weight of the molded part.

  Moreover, in the portion of the main body of the clip other than the portion seated on the higher side of the mold forming portion, the pressing holding force by the clip is transmitted through the ribs in the partition, so that Unlike the case where the entire thick portion of the molded portion is pressed and held, the force for lifting the molded portion itself and the clip is relatively small. As a result, it is possible to prevent the occurrence of secondary problems due to a decrease in assembly accuracy, and to eliminate the secular change and the detachment of the clip when the door is suddenly closed.

  According to the first and second aspects of the present invention, since it is not necessary to increase the thickness of the molded part in order to absorb the difference in height of the panel, the weight can be reduced by reducing the weight of the molded part.

  Moreover, because the ribs in the shape of the partition are set without increasing the thickness of the molded part, the shape of the clip main body does not need to be a complicated shape following the difference in height of the panel, In addition to the improvement, it is possible to prevent the occurrence of secondary problems due to a decrease in assembly accuracy, and to prevent the clip from coming off when the door is aged or when the door is suddenly closed.

  According to the invention described in claim 3, the two ribs are polymerized while being in contact with each other, and at least the rib on the mold forming part side is in the main part of the clip, or the rib on the main part of the clip is the mold forming part. Therefore, the relative positioning accuracy between the two becomes higher and the anti-rotation effect of both is expected.

  According to the invention described in claim 4, since a bag-like locking groove that is locked while the front end of the main body portion of the clip is seated is formed in the lower portion of the molded portion, It is possible to more reliably prevent the tip end of the main body portion of the clip from being lifted, and it is advantageous for improving the appearance.

  According to the seventh aspect of the present invention, the clip rib main body portion is formed so that the rim rib is continuously formed on the wall portion forming the bag-like locking groove and is inscribed in the rim rib including the wall portion. Therefore, it is possible to improve the relative positioning accuracy between the molded part and the clip, and it is advantageous in improving the appearance.

  According to the eighth aspect of the present invention, since the main body of the clip has the same color as the door parting seal, it is more advantageous in improving the appearance.

  According to the invention of claim 9, since the mold part of the door parting seal has a function of receiving the upper end portion of the side sill parting seal and concealing it by holding it under pressure, This also improves the appearance.

  FIGS. 1-11 is a figure which shows 1st Embodiment of the weather strip attachment structure based on this invention more concretely, Comprising: The example at the time of applying to the attachment structure of a door parting seal is shown. 1 shows a perspective view of the automobile, FIG. 2 shows a perspective view seen from the outside of the part A in FIG. 1, and FIGS. 3 to 6 show the main part of FIG. 7 to 11 are enlarged sectional views of the respective parts in FIG.

  In FIG. 1, 2 is a left front door, 3 is a left rear door, and these doors 2 and 3 are either a door outer panel 2a or 3a and a door inner panel 2b or as shown in FIGS. 3b is hemming-coupled at the hemming coupling part 4 or 5. A door parting seal is formed along the vertical direction on the front edge of the rear door 3 that faces the rear edge of the front door 2 and below the so-called door waist (belt line). 6 is disposed. Since the door parting seal 6 is provided, the hemming joint 4 of the front door 2 comes into pressure contact with the seal lip 13 of the door parting seal 6 when both the doors 2 and 3 are closed as will be described later. The parting part, that is, the gap between the doors 2 and 3 is sealed.

  As shown in FIGS. 3 to 8, the door parting seal 6 includes a general part (extrusion molded part) 7 that is extruded as a long and uniform cross-sectional shape by a known extrusion molding method, and a lower end of the general part 7. The terminal portion 9 is provided as a molded portion integrally formed by die molding with the joining line 8. As shown in FIGS. 3 and 4, the terminal portion 9 is formed as a wide tongue-shaped portion that is largely offset toward the door inner panel 3 b as shown in FIGS. It is firmly fixed to the door inner panel 3b with a clip 23 having a substantially similar shape superimposed on the terminal portion 9.

  The door parting seal 6 including the general portion 7 and the terminal portion 9 is formed of a rubber material such as EPDM or a soft resin material equivalent to the rubber material, and the clip 23 is formed of a relatively hard resin material. .

  As shown in FIGS. 4 and 7, the general part 7 of the door parting seal 6 has a substantially U-shaped cross section with a cored bar 10 that is fitted and held in the hemming joint 5 at the front end of the rear door 3. A welt portion 11, an intermediate web 12 extending obliquely from one side wall portion of the welt portion 11, an intermediate web 12 extending from the tip of the intermediate web 12 toward the base side of the welt portion 11, and the intermediate web And a seal lip 13 having a cantilever support shape that is thinner than 12 and curved in a substantially arc shape. The seal lip 13 forms a gap portion 14 having a substantially sectoral cross section together with one side wall portion of the welt portion 11 and the intermediate web 12 (see FIG. 7).

  As shown in FIG. 7, regardless of whether both doors 2 and 3 are open or closed, the end 15 of the corner formed by the intermediate web 12 and the seal lip 13 is the door 2. , 3 is set so as not to protrude outward from the outer surface, and the core metal 10 is embedded in the welt portion 11, whereas the intermediate web 12 is not embedded with the core metal. The intermediate web 12 can be bent and deformed from its root portion which is a connection portion with the welt portion 11.

  Thereby, when the welt part 11 is fitted to the hemming joint part 5 on the rear door 3 side and the door parting seal 6 is fixed, the corner part formed by the intermediate web 12 and the seal lip 13 is the hemming joint in the rear door 3. The front wall surface, which is a stepped wall portion close to the portion 5, is pressed against the front wall surface.

  On the other hand, the terminal part 9 of the door parting seal 6 has a wide tongue-like shape that is largely offset with respect to the longitudinal axis of the general part 7 as described above. As apparent from FIGS. 4, 5, and 9, at the lower end portion of the rear door 3 on the vehicle interior side where the terminal portion 9 is located, the general inner surface 3 c of the door inner panel 3 b and the hemming joint 5 It has a shape having a large height difference (step) G from the vicinity. In order to follow the shape of the door inner panel 3b having the height difference G and to seat the terminal portion 9 with the shape portion as a seating surface Q, the basic shape of the terminal portion 9 is that of the door inner panel 3b on the higher side. It is formed as a substantially plate-like thing that is curved three-dimensionally by approximating the shape of the seating surface Q with the above-mentioned height difference so as to straddle both the inner side surface 3c of the general part and the vicinity of the hemming coupling part 5 on the lower side. It is.

  As apparent from FIGS. 4 and 5, the door inner panel 3b is formed with a square hole-shaped mounting hole 16a on the inner side surface 3c, which is the higher side of the door inner panel 3b. Similarly, a square hole-shaped mounting hole 16b is formed at a position corresponding to the mounting hole 16a on the inner panel 3b side.

  Further, as is apparent from FIGS. 4, 6 and 8, 9, in the terminal portion 9, the welt portion 11 on the general portion 7 side disappears while gradually changing, and instead continues to the one on the general portion 7 side. The intermediate web 12 and the seal lip 13 are integrally extended from the terminal portion 9.

  As is clear from FIGS. 4, 5 and 9, the hemming joint 5 at the front end of the rear door 3 is partially cut away at the portion corresponding to the terminal portion 9 of the door parting seal 6. The hemming state is incomplete, but the hemming bond strength is not hindered.

  As shown in FIGS. 2, 9, and 11, a plurality of crossed bead portions 17 are formed to protrude on the back surface of the substantially plate-like terminal portion 9 that is curved three-dimensionally as described above, and double-sided adhesive The tape 18 is affixed, and the bead portion 17 and the double-sided adhesive tape 18 are seated on the seating surface Q on the door inner panel 3b side, whereby the terminal portion 9 is positioned. As is clear from FIGS. 9 to 11 and the like, the bead portion 17 and the like set on the back surface of the terminal portion 9 as described above are seated on the seating surface Q on the door inner panel 3b side, so that the terminal portion 9 itself and A predetermined gap is ensured between the seating surface Q on the door inner panel 3b side. Therefore, even if the shape of the seating surface Q on the door inner panel 3b side varies, the influence on the mounting state of the terminal portion 9 is small.

  On the other hand, as shown in FIGS. 5 and 6, a plurality of rib-shaped ribs 19 having an arcuate shape are formed on the surface side of the terminal portion 9 on which the clip 23 is to be covered. An edge rib 20 is formed on the peripheral edge portion that forms the contour of 9. The ribs 19 in the form of partition walls are formed on the surface of the terminal portion 9 excluding the highest flat portion, and the arc surface shape at the tip of each rib 19 is the curved arc shape of the terminal portion 9 itself. Unlike the case, it has a smooth circular arc shape that is convex toward the anti-seat surface Q side. Further, a wall portion 21 is formed so as to protrude from the lowermost portion of the surface of the terminal portion 9 so as to be continuous with the rim rib 20, and a bag-like shape is formed between the wall portion 21 and the partition-like rib 19. The locking groove 22 is formed.

  Thereby, when the clip 23 is overlapped and arranged on the surface side of the terminal portion 9 as will be described later, the peripheral portion of the main body portion 24 of the clip 23 is inscribed to the rim rib 20 and is so-called rimmed, and the bag-like locking As shown in FIG. 9, the groove 22 is inserted so that the front end of the main body 24 of the clip 23 is seated, so that the bag-like locking groove 22 receives the front end of the main body 24 of the clip 23. And conceal it.

  As shown in FIGS. 3 to 6 and FIG. 9, the clip 23 is formed by using a wide and maximal plate-like main body portion 24 whose plan view shape is substantially similar to the terminal portion 9 as a main element, An anchor portion 25 having a rectangular cross section is projected from a portion of the back surface of the main body portion 24 which is seated on the flat portion on the highest side of the terminal portion 9. In other words, the anchor is attached to a portion of the main body portion 24 of the clip 23 that is in close contact with the terminal portion 9 and that is far from the distal end portion of the main body portion 24 to be inserted into the bag-like locking groove 22. Section 25 is set.

  Further, the main body 24 of the clip 23 has a shape curved from the highest portion of the surface of the terminal portion 9 in accordance with the curvature of the arc surface at the tip of the partition wall-like rib 19 that is continuous therewith. Thus, the degree of curvature or curvature is smoother than that of the terminal unit 9 itself. As shown in FIGS. 5 and 6, a plurality of bead portions 26 for reinforcement are formed on the back surface of the main body portion 9.

  Then, as shown in FIGS. 4 to 6 and FIG. 9, the front end portion of the main body portion 24 is shaped like a bag while the main body portion 24 of the clip 23 is inscribed so as to be inscribed in the edge rib 20 on the surface side of the terminal portion 9. The main body portion 24 of the clip 23 is placed on the terminal portion 9 in an overlapping manner, and the anchor portion 25 is placed on both the terminal portion 9 and the door inner panel 3b side. The terminal portion 9 is pressed and held between the door inner panel 3 b and the main body portion 24 of the clip 23 by being fitted and held in the mounting holes 15 and 16.

  As a result, as is apparent from FIG. 9, the highest flat portion of the main body 24 of the clip 23 is seated on the terminal portion 9 with a relatively large area, but in the other portions, the partition wall The arcuate tip surface of the rib 19 is in a state where it is in close contact with or slightly in contact with the inner surface of the main body 24 of the clip 23.

  That is, in the state where the terminal portion 9 is pressed and held by the clip 23 as shown in FIGS. 9 and 11, a relatively large gap portion 27 is formed between the terminal portion 9 and the main body portion 24 of the clip 23. Only the plurality of partition-like ribs 19 described above are interposed in the gap 27.

  At the same time, square holes are used as the mounting holes 15 on the door inner panel 3b side and the mounting holes 16 on the terminal 9 side, while square pillars are used as the anchor part 25 on the clip 23 side. As a result, the clip 23 is prevented from rotating.

  In addition, when the clip 23 is normally attached to the terminal portion 9, the plurality of ribs 19 on the terminal portion 9 side and the plurality of bead portions 26 on the main body portion 24 side of the clip 23 do not interfere with each other. Moreover, as apparent from FIGS. 3 to 5, the plurality of ribs 19 and the plurality of bead portions 26 are formed so as to be displaced from each other.

  When the door parting seal 6 including the terminal portion 9 is, for example, black, the clip 23 is at least the main body 24 having the same black color as that of the door parting seal 6. Thereby, even if the terminal part 9 is exposed together with the clip 23 when the door is opened, the viewer does not feel uncomfortable.

  4 and 5, a belt-shaped side sill parting seal 28 for sealing a gap as a parting part between the rear door 3 and the side sill on the vehicle body side is provided at the lower end of the door inner panel 3b on the vehicle interior side. The clip 29 is disposed on the front side of the rear door 3 of the side sill parting seal 28 and interferes with the terminal portion 9 of the previous door parting seal 6.

  Therefore, in the present embodiment, as shown in FIG. 10, the upper end portion of the side sill parting seal 28 is overlapped with the terminal portion 9 and then pressed together with the terminal portion 9 by the clip 23. keeping. Thus, consideration is given so that appearance does not deteriorate due to interference between both terminal portions.

  7-9, the code | symbol P1 shows the opening / closing locus | trajectory of the front door 2, and the code | symbol P2 shows the opening / closing locus | trajectory of the rear door 3, respectively. Moreover, the code | symbol P3 of FIG. 9 shows the door hinge center position of the rear door 3. As shown in FIG.

  Therefore, according to such a mounting structure of the door parting seal 6, as shown in FIGS. 3 to 6, in the general portion 7, the welt portion 11 is firmly fitted to the hemming joint portion 5 at the front end portion of the rear door 3. On the other hand, in the terminal portion 9, the terminal portion 9 is firmly pressed and fixed to the seating surface Q having a large height difference in the door inner panel 3b by the wide clip 23.

  In this case, the highest flat portion of the terminal portion 9 is directly pressed and held by the main body 24 of the clip 23, while the terminal portion 9 other than the highest flat portion is also held. In other words, in the portion where the difference in height is most pronounced, the terminal portion 9 and the main body portion 24 of the clip 23 are not in direct contact with each other, and a so-called lightening structure is formed by the gap portion 27. A pressing holding force by the clip 23 is transmitted to the terminal portion 9 through the plurality of partition-like ribs 19.

  For this reason, not only can the weight of the terminal portion 9 be reduced compared to the case where the entire gap portion 27 has a solid structure, but also the restoring reaction force exerted on the clip 23 by the terminal portion 9 can be relatively suppressed. .

  As a result, the pressing and holding force of the clip 23 can be reliably exerted even at a portion of the terminal portion 9 far from the anchor portion 25, and not only the terminal portion 9 itself but also the clip 23 can be prevented from being lifted. In particular, the distal end portion of the main body 24 of the clip 23 farthest from the anchor portion 25 is inserted into the bag-like locking groove 22 and locked, so that the appearance of the clip 23 is improved and the lifting of the clip 23 is more reliably performed. Can be prevented.

  As a result, it is possible to stably maintain the assembly accuracy of the terminal portion 9 among the door parting seals 6 and to prevent the occurrence of secondary problems such as poor sealing performance of the sealing portion and improved door closing force. In addition, it is possible to prevent the clip 23 from coming off due to secular change or when the door is suddenly closed.

  In addition to the clip 23 being overlapped with the terminal portion 9 being inserted and locked in the bag-shaped locking groove 22 as described above, the clip 23 is overlapped with the edge rib 20 on the terminal portion 9 side. Therefore, the relative positioning accuracy is improved as well as the appearance.

  And the main body part 24 of the clip 23 which presses and fixes the terminal part 9 to the door inner panel 3b while covering almost the entire surface of the terminal part 9 has the shape of the door inner panel 3b and the terminal part 9 having a height difference. Since it has a smooth three-dimensional curved shape without being faithfully copied, the appearance can be improved.

  Here, as apparent from FIG. 9, the plurality of partition-like ribs 19 set in the terminal portion 9 are located in the gap portion 27 formed by the terminal portion 9 and the main body portion 24 of the clip 23. It has a function of exerting a pressure holding force by the clip 23 on the terminal portion 9 side. Therefore, instead of projecting and forming a plurality of partition-like ribs 19 from the terminal portion 9 as shown in FIG. Function is demonstrated.

  Further, the parting portion formed by the front fender portion and the front door 2 shown in FIG. 1 also employs the door parting seal 6 having substantially the same structure as described above. The structure of the terminal unit 9 similar to the above can be adopted.

  12-14 is a figure which shows 2nd Embodiment of the attachment structure of the weather strip which concerns on this invention, Comprising: The same code | symbol is attached | subjected to the part which is common in previous 1st Embodiment.

  As is clear from a comparison between FIGS. 5 and 6 and FIGS. 12 and 13, in the second embodiment shown in FIGS. 12 and 13, a plurality of sets set on the back surface of the main body 24 in the clip 23 in FIG. 6. The protruding length of the reinforcing bead portion 26 is increased, and as shown in FIGS. 13 and 14, the ribs 36 are formed as partition walls like the ribs 19 on the terminal portion 9 side. In a state where the terminal portion 9 is pressed and held by the clip 23, the tip of the rib 36 on the clip 23 side is seated on the terminal portion 9, and the rib 36 on the clip 23 side and the rib 19 on the terminal portion 9 side Are in contact with each other and overlap with each other, and the two are in a so-called bottom relationship with each other. In this case, it is not always necessary that both of them bottom out to the other side, and it is sufficient that at least one of them bottoms out to the other side.

  Furthermore, as shown in FIG. 13, if the number of ribs 36 set on the back surface of the main body 24 of the clip 23 is three, for example, at least one pair of ribs 36 and 19 overlapping each other as shown in FIG. The vertical relationship between them is set to be opposite to the vertical relationship between the other two pairs of ribs 36 and 19. Accordingly, the relative positioning effect between the terminal portion 9 and the clip 23 in the vertical direction of FIG. 13 is exhibited, and the effect of stopping the rotation between the terminal portion 9 and the clip 23 is also exhibited at the same time.

  Therefore, also in the second embodiment, substantially the same effect as in the first embodiment can be obtained.

  3 and 6 and FIGS. 12 and 14, the wall 21 and the locking groove 22 that are essential on the side of FIGS. 3 and 6 are formed as shown in FIGS. It can be abolished.
