Description

  The present invention relates to a matching part structure for vehicle interior parts, and more particularly to a matching part structure for two adjacent interior parts covering a vehicle interior wall surface along a door opening of a vehicle.

  The interior walls of automobiles and the like are covered with a plurality of resin interior parts such as trims and roof linings, and are beautifully decorated. As described in Patent Document 1, these interior parts are fastened to the vehicle body panel using a clip, and at the mating portion between adjacent interior parts, the claw portion provided at the edge of one interior part is the other. A method is adopted in which the clip is omitted as much as possible, for example, by engaging with the edge of the interior part.

  Further, since interior parts such as trims and roof linings are large resin molded parts, it is necessary to assume dimensional errors during molding and dimensional changes due to thermal shrinkage due to changes in outside air temperature. Therefore, in order to absorb these dimensional errors and dimensional changes at the mating part between the interior parts, a mating part structure is adopted in which one edge part is overlapped with the other edge part instead of abutting the edge part or step part. Is done.

  For example, in the installation of the interior parts at the rear of the vehicle as shown in FIG. 1, after the roof lining 2 is installed, the quarter upper trim 3 and the quarter trim 4 are installed in this order, and the quarter upper trim 3 and the quarter trim 4 are aligned. In the portion (3b / 4a), as shown in FIG. 2, a parting line is defined by the lower edge 3b of the quarter upper trim 3 and the upper edge 4a of the quarter trim 4 abutting each other.

  On the other hand, at the mating part (2b / 3a) with the roof lining 2, as shown in FIG. 3, the upper edge 3a of the quarter upper trim 3 is overlapped on the surface side of the lower edge 2b of the roof lining 2, and below that A parting line is defined by the upper edge 3a of the quarter upper trim 3 by pushing and engaging the clip 3f provided on the back side into the hole of the vehicle body panel. However, in the mating portion (2b / 3a), the edges are simply overlapped with each other, so that there is a possibility that a gap is generated in the mating portion at a position away from the clip 3f.

  In addition, as shown in FIG. 3, when a container 15 such as an impact absorbing pad or a curtain airbag is pushed inside the roof lining 2, the extrusion by the container 15 and the engaging force by the clip 3 f Must be set in a well-balanced manner so that there are no gaps in the parting line. However, in the roof lining 2 which is a large molded part, the shape accuracy at the edge tends to be relatively lowered, which also causes a gap in the mating portion.

  Therefore, it can be said that the joint portion in the vicinity of the back door opening 10 which is the rearmost end of the roof lining 2 is a portion where a gap is likely to be formed for the above-mentioned molding reasons. Further, as shown in FIG. In the case where the notch 30 that is inserted through the balancer 12 of the back door 11 is provided at the edge along the back door opening 10 (opening trim 5), the rigidity of the edge located above the notch 30 is high. There is a problem that a gap is likely to be generated at the mating portion due to a relative decrease and insufficient pressing force on the roof lining 2.

  Further, when the opening trim 5 is fitted to the flange 13 of the back door opening 10, the lower side from the upper side of the back door opening 10 is the same as when the interior parts (2, 3, 4) are mounted. The opening trim 5 is fitted to the edge, but at the joint portion (2b / 3a) of the roof lining 2 and the quarter upper trim 3, the quarter upper trim 3 polymerized on the surface side is likely to float, and the quarter upper There was also a problem that the lip (51) of the opening trim 5 that should cover the edge of the trim 3 was easily assembled in a state of being submerged under the quarter upper trim 3.

  As described above, the mating part structure of the interior part according to the present invention is a door opening of the second interior part in the mating part structure of two interior parts adjacent to each other via a parting line that terminates at the door opening of the vehicle. Since the engaging portions (32, 34) that engage with the edge ends of the mating portions of the first interior part are provided on the back side of the edge along the part, the opening side edge of each interior part Even without setting a fixed location such as a clip in the vicinity, the engaging part can be used to cut off the mating part only with each interior part, and the parting line becomes uncertain due to an increase or decrease in the amount of polymerization of each interior part In addition, it is possible to prevent a gap from being generated in the mating portion due to the floating of the second interior component or the sinking of the first interior component in the mating portion of each interior component, and a good appearance can be obtained in the mating portion.

  In the present invention, the opening of the first interior part with which the engagement portion engages is bent from the edge end portion extending along the vehicle interior wall surface and extends toward the vehicle interior wall surface. An engaged edge (2c) continuous to the side edge is provided, and the engaging parts (32, 34) of the second interior part are in contact with the end surface and the back surface of the engaged edge. In the configuration configured to engage, the direction in which the polymerization amount of each interior part increases or decreases (in the embodiment, the vehicle up-down direction) and the direction in which the polymerization of each interior part separates from each other (the implementation) At the same time as the position restriction with respect to the vehicle width direction in the embodiment, the position restriction with respect to the direction in which the polymerization of the interior parts deviates along the parting line (the vehicle longitudinal direction in the embodiment) can be performed.

  In the present invention, in the aspect in which the engaged edge portion (2c) extends obliquely between the edge end portion of the first interior part and the opening side edge portion, With the movement of the second interior part at the time of assembly such that the edge part is brought close to the edge part of the first interior part and the clip provided elsewhere is pushed into the hole of the vehicle body panel and engaged. The elastically deformed portion of the first interior part in the direction intersecting the push-in direction is induced by the engaged edge extending obliquely, and the engaging portion of the second interior part is engaged by this elastic deformation. It is possible to pass from the side of the edge to the back side, and assembly can be performed without difficulty. In addition, the engaged edge portion (spotted edge portion) formed obliquely at the corner portion of the first interior component can prevent breakage of the corner portion of the first interior component during storage and transportation before assembly, Moreover, the moldability of the first interior part is also good.

  In the present invention, the engaging portion of the second interior part is spaced from the back side of the opening side edge and protrudes toward the first interior part and is provided on the back surface of the engaged edge. An engaging projection (32) that abuts, and an engaging groove (34) that is defined between the engaging projection and the opening side edge and abuts against the end surface of the engaged edge. In this aspect, it is possible to positively engage with the engaged edge of the first interior part while having a simple shape. In particular, even in the inclined engaged edge, the engagement and the two or three directions are possible. Can be reliably controlled.

  In the present invention, a latching piece (33) that is sandwiched in the fitting groove of the opening trim together with the flange is extended to the opening side edge (3c) of the second interior part, and the engagement In the aspect in which the protrusion and the engagement groove are formed integrally with the base end portion of the hooking piece, the opening side edge of the second interior part is hooked on the vehicle body side via the hooking piece and the opening trim. The edge portion of the first interior part is engaged with the engaging part of the second interior part that is stopped and hooked in this way, so that the position of the mating part is not limited to each other. Positioned relative to the side. In addition, the engaging part (engagement protrusion and engagement groove) which protrudes from the back surface side of the second interior part and is undercut in the molding die of the second interior part is similarly an undercut. Since the engaging part can be formed simultaneously with the slide unit for forming the latching piece, it is not necessary to add a new slide unit for the engaging part, which is advantageous in terms of manufacturing cost. It is.

  In the present invention, in the aspect in which the engagement protrusion (32) has the inclined guide edge (32c) on the opposite side to the engagement groove, the engagement is performed during the movement of the second interior part as described above. Elastic deformation of the first interior part is more easily induced by the inclined guide edge of the protrusion, and the engaging portion is easily assembled to the edge (engaged edge, corner edge) of the first interior part. it can.

  In the present invention, a latching piece (33 ') that is clamped in the opening groove of the opening trim together with the flange is extended to the opening side edge of the second interior part. In the aspect in which the side edge of the portion is provided with a deflection edge (33a) that is deflected and pressed against the flange side, when the opening trim is fitted to the flange of the door opening, the first interior part Even when the second inner part and the latching piece are lifted by the abutting edge of the second inner part being in contact with the latching piece of the second interior part, the side edge part (upper side edge part) of the latching piece is also used. When the deflection edge deflected to the flange side is pressed against the flange, the latching piece is securely fitted together with the flange to the opening trim that is fitted from above, so that the gap between the mating portions is prevented, Assembling property can be maintained well.

  In the above aspect, if the deflection edge portion is formed as a flexible piece portion that is continuous with the latching piece via the thinning portion (33b) and can be bent by the pressure contact, the deflection edge portion is fitted to the opening trim. Since the deflection edge is bent along the flange and flattened after that, the thickness of the latching piece inserted into the opening trim is kept small while maintaining the ease of assembly. Deformation can be kept to a minimum.

A notch (30) is formed, and the opening side edge of the quarter upper trim is divided into an upper edge (3c) and a lower edge (3d) by the notch, and the latch In the aspect in which the piece (33) is extended to the upper edge, the rigidity is lowered by the notch, and the upper side of the quarter upper trim is insufficient in the pressing force against the edge of the first interior part. Part is rigidity decrease is compensated by being engaged with the edge of the first interior part by the engagement portion, it is possible to obtain a parting portion of the high appearance. Moreover, at the time of assembling the second interior part, the edge of the second interior part can be easily elastically deformed due to a reduction in rigidity due to the notch, and there is an advantage that the assemblability is good.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a back door opening 10 of a vehicle 1 provided with a quarter upper trim 3 and a roof lining 2 which are interior parts in which the mating structure according to the present invention is implemented, as viewed from the rear of the vehicle. In the figure, a quarter upper trim 3 and a quarter trim 4 are mounted vertically on the vehicle interior side wall (quarter) located on the side of the back door opening 10, and the upper end of the quarter upper trim 3 is connected to the roof lining 2. Adjacent.

  As shown in FIGS. 1 and 7, the outer panel 1 a and the inner panel 1 b constituting the vehicle body of the vehicle 1 are joined at a flange 13 (opening flange) around the back door opening 10 at the rear of the vehicle body. An opening trim 5 integral with the weather strip is fitted to the flange 13. The back door 11 schematically shown in FIG. 1 is attached to the upper edge of the back door opening 10 so as to be openable and closable via a hinge (not shown), and the back door 11 is opened at one side of the back door 11. And a balancer 12 that assists the opening operation.

  The balancer 12 has a distal end portion rotatably connected to an inner surface side portion of the back door 11, and a base end portion 12a rotatably connected to the vehicle body inner wall (inner panel 1b) via a bracket. Accordingly, a notch 30 for inserting the balancer 12 is provided near the upper end of the edge along the back door opening 10 of the quarter upper trim 3. FIG. 2 is a side view of the quarter upper trim 3 as viewed from the vehicle interior side. Although omitted in the figure, FIG. 2 corresponds to the closed position of the back door 11, the balancer 12 is positioned at the lowermost portion of the notch 30, and the rod of the balancer 12 is in an immersive state. The vicinity of the cutout portion 30 of the quarter upper trim 3 is a bulging portion 31 for accommodating the base end portion 12a of the balancer 12 and its rotating connecting portion, and the cutout portion 30 obliquely crosses the bulging portion 31. Is formed.

  As described above, the quarter upper trim 3 is mounted on the vehicle interior side wall after the roof lining 2 is mounted on the vehicle interior ceiling and before the quarter trim 4 is mounted. That is, as shown in FIG. 2, two locking pieces 3e are extended downward from the lower edge 3b of the quarter upper trim 3, and clips set on these locking pieces 3e are formed in the inner panel 1b. 2 and 3, the upper edge portion 3 a of the quarter upper trim 3 is overlapped with the surface side of the lower edge portion 2 b of the roof lining 2, so that the quarter upper trim 3 A clip 3f provided on the back side of the upper edge 3a is pushed into a hole in the vehicle body panel and engaged.

  Therefore, a parting line (3a) is defined by the upper edge portion 3a of the quarter upper trim 3 at the joining portion (2b / 3a) of the quarter upper trim 3 and the roof lining 2 (2b / 3a). As described above, since the edges of the mating portion (2b / 3a) are only overlapped with each other, a gap is likely to be generated in the mating portion at a position away from the clip 3f. In particular, in the illustrated example, the parting line (3a) wraps outward in the vehicle width direction on the rear end side in the vehicle front-rear direction and ends at the opening trim 5 (weather strip) fitted to the flange 13 of the door opening 10. However, since the rotation connecting portion of the balancer 12 is disposed in the vicinity thereof, the clip cannot be installed, which also causes a gap.

  As shown in FIG. 2, the opening side edges 2d, 3c, 3d, and 4d of the roof lining 2, the quarter upper trim 3, and the quarter trim 4 that are adjacently arranged vertically along the back door opening 10 are as shown in FIG. Covered by the lip 51 of the opening trim 5. However, the covering of the lip 51 made of only an elastomer such as a synthetic rubber or a soft resin is positively applied to the main body (the fitting groove 50) of the opening trim 5 in which a reinforcing material such as metal is inserted. There is no function to position automatically.

  Therefore, in the present invention, as shown in FIGS. 4 to 7, on the back surface side of the upper edge portion 3 a of the quarter upper trim 3 disposed on the front surface side of the mating portion (2 b / 3 a) adjacent to the back door opening 10. The latching piece 33 fitted to the opening trim 5 is provided together with the flange 13 of the back door opening 10, and the latching piece 33 is engaged at the base end side with the lower edge 2 b of the roof lining 2. By providing the protrusion 32 integrally, a gap between the mating portions (2b / 3a) is prevented, and a good appearance can be obtained at this portion.

  The latching piece 33 is folded back from the opening side edge 3c extending above the notch 30 of the opening side edge (3c, 3d) along the back door opening 10 of the quarter upper trim 3 to the back surface side. And is formed in a U-shaped cross section so that the inner edge of the opening trim 5 is wound around and can be hooked into the fitting groove 50. The engaging protrusion 32 is spaced apart from the back surface of the opening side edge 3c of the quarter upper trim 3 and protrudes upward from the edge of the latching piece 33, that is, toward the roof lining 2, whereby the engaging protrusion 32 is provided. And an engagement groove 34 is defined between the opening side edge 3c and the back surface.

  On the other hand, the engaged edge 2c of the roof lining lower edge 2b corresponding to the engagement groove 34 is from the end of the lower edge 2b on the back door opening 10 side as shown in FIG. 4 or FIG. It bends obliquely upward and outward in the vehicle width direction, extends toward the vehicle interior wall surface (inner panel 1b), and continues to the opening side edge 2d of the roof lining 2. That is, the engaged edge 2c is formed as a corner edge obtained by obliquely cutting off the corner between the lower edge 2b of the roof lining 2 and the opening edge 2d.

  When the quarter upper trim 3 configured as described above is assembled, the lower edge 3b of the quarter upper trim 3 is locked to the inner panel 1b, and then the upper edge 3a is used as the surface of the lower edge 2b of the roof lining 2 When the clip 3f is pushed to engage with the hole of the vehicle body panel, the front end of the engaging projection 32 comes into contact with the engaged edge 2c of the roof lining lower edge 2b, as shown in FIG. The upper edge 3a of the quarter upper trim that extends above the notch 30 and the hooking edge 32c that is inclined toward the tip of the engaging protrusion 32 are guided by the inclined roof lining lower edge 2b. Elastic deformation in the direction intersecting the pushing direction of the stop piece 33 is induced, the tip of the engaging protrusion 32 passes through the inclined engaged edge 2c from the lower side, and the engaging protrusion 32 is engaged. Together to engage the rear surface of the part 2c, the engagement groove 34 engages the end face of Hikakarigoen portion 2c.

  As described above, the engagement protrusion 32 and the engagement groove 34 extending on the back surface side of the upper edge portion of the quarter upper trim 3 at the rear end of the alignment include the inclined engaged edge portion of the roof lining lower edge portion 2b. Due to the engagement with 2c, the position of the roof lining lower edge 2b and the quarter upper trim upper edge 3a are regulated in the vehicle width direction and the vehicle front-rear direction, and a gap is formed in the mating portion (2b / 3a). At the same time, the overlapping position of the roof lining lower edge 2b and the quarter upper trim upper edge 3a in the vertical direction of the vehicle is restricted, and only the interior parts (2, 3) are independent of the attachment of the clip 3f. With this, the parting (3a) of the mating part (2b / 3a) can be taken out.

  Accordingly, it is not necessary to set up a mounting structure such as a roof lining built-in object 15 that pressurizes the roof lining 2 toward the vehicle interior side and a clip that engages the quarter upper trim 3 on the inner panel 1b side at the rear end of the alignment. This is advantageous in terms of cost saving and weight reduction, and also provides an advantage of improving the degree of freedom of the structural layout in the part.

  In addition, due to the cutout portion 30 through which the balancer 12 of the back door 11 is inserted, the vicinity of the opening side edge portion 3c on the upper side of the quarter upper trim 3 is a portion where rigidity is likely to be insufficient compared to other portions. By forming the engaging protrusion 32 and the engaging groove 34 integrally with the latching piece 33 on the opening side edge 3c, it is possible to secure a supporting force for the opening side edge 3c using the fitting force of the opening trim 5. . The lack of rigidity in the vicinity of the opening side edge 3c brings about an advantage that the elastic deformation of the quarter upper trim upper edge 3a and the latching piece 33 (engagement protrusion 32) is easily induced during assembly. Combined with the inductive action of elastic deformation by the inclined edge portion 32c of the mating projection 32 and the engaged edge portion 2c of the roof lining lower edge portion 2b, good assemblability can be obtained.

  Further, the engagement protrusion 32 extending on the back surface side of the upper edge portion 3a of the quarter upper trim has a shape that is an undercut in the molding die. Simultaneous molding by a slide unit for molding the stopper piece 33 is possible, and there is no need to add a separate slide unit. In addition, since the engagement protrusion 32 is simple and small in shape, it can be implemented with a slight modification to the existing slide mold.

  Next, FIGS. 8 to 12 show a mating portion (2b / 3a) structure according to a second embodiment of the present invention. This second embodiment is different from the first embodiment shown in FIGS. 4 to 7 only in that the latching piece 33 ′ has a deflection edge 33a, and the other basic structure is the same. The same members are denoted by the same reference numerals and the description thereof will be omitted.

  The base end portion of the latching piece 33 provided on the back surface side of the upper edge portion 3a of the quarter upper trim 3 comes into contact with the lower edge portion 2b of the roof lining 2 so that the roof lining lower edge portion 2b and the quarter upper trim upper edge portion. As described above, the superposition position of the vehicle 3a in the vertical direction of the vehicle 3a is restricted, and the parting (3a) of the mating portion (2b / 3a) is generated. However, until the latching piece 33 is fitted to the opening trim 5 together with the flange 13 of the back door opening 10 and the assembly is completed, there may be a gap between the latching piece 33 and the flange 13. It is necessary to carefully perform the work of fitting the opening trim 5 at this portion.

  That is, due to dimensional tolerances and inevitable shape errors of the roof lining 2 and the quarter upper trim 3 made of a large resin molded product, the latching piece 33 tends to float from the flange 13 of the back door opening 10. In this state, when the fitting operation of the opening trim 5 is performed along the back door opening 10 from the upper side to the lower side, the fitting groove 50 of the opening trim 5 enters under the floating retaining piece 33. Inadequate attachment is likely to occur.

  Therefore, in the second embodiment shown in FIGS. 8 to 12, the hooked portion of the latching piece 33 ′ held in the fitting groove 50 of the opening trim 5 together with the flange 13, that is, formed in a U-shaped cross section. A deflection edge 33a that deflects toward the flange 13 and extends obliquely is integrally formed on the side edge above the flat portion on the front end side of the latch piece 33 '. The deflection edge portion 33a exceeds the dimensional reference surface by the amount of the deflection with respect to the flat surface of the latching piece 33 'which becomes the design dimensional reference surface to be brought into contact with the flange 13 in the assembled state. It extends to.

  Therefore, if the above-described lifting of the latching piece 33 ′ is within the extension amount range of the deflection edge 33 a, the upper end of the deflection edge 33 a is always in contact with or pressed against the flange 13. In this state, if the opening trim 5 is fitted along the back door opening 10 from the upper side to the lower side, the latching piece 33 ′ is naturally formed by the deflecting edge 33 a that is pressed against the flange 13 and inclined. Are inserted into the fitting groove 50 and are held together with the flange 13 in the fitting groove 50 of the opening trim 5.

  In the state where the opening trim 5 is assembled, the deflection edge 33a of the latching piece 33 'is clamped in the fitting groove 50 in a state where the deflection is partially corrected by elastic deformation by the clamping pressure of the opening trim 5. The reaction force due to this elastic deformation can contribute to preventing the latching piece 33 ′ from being displaced by the pressing piece 33 ′ being pressed against the flange 13 in the fitting groove 50. However, if the reaction force is too large, it will not only be a resistance against the introduction of the latching piece 33 ′, but also the fitting groove 50 of the opening trim 5 will be deformed more than necessary.

  Therefore, in the latching piece 33 ′ of the second embodiment, the deflection edge 33 a is a flexible piece part that is continuous with the flat main body part of the latching piece 33 ′ via the thinned portion 33 b, and the above opening is performed. When the trim 5 is fitted, the deflection edge 33a is easily elastically deformed with the reduced thickness portion 33b as a starting point due to the clamping pressure of the opening trim 5. With this structure, after the opening trim 5 is fitted, the deflection edge 33a 'is flattened along the flange 13 and fitted into the opening trim 5, as shown by a two-dot chain line in FIG. The thickness of the piece 33 'can be kept small, and the deformation of the opening trim 5 can be kept to a minimum.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.

  For example, in each of the above embodiments, the engaging portion includes the engaging protrusion 32 protruding from the proximal end side of the latching pieces 33 and 33 ′, and between the engaging protrusion 32 and the back surface of the opening side edge 3 c. Although the case where the engagement groove 34 is defined is shown in FIG. 1, the engagement portion is configured only by a flat step portion having a level corresponding to the bottom side of the engagement groove 34 without forming the engagement protrusion 32. You can also.

  In that case, the roof lining lower edge portion 2b and the quarter upper trim are brought into contact with the bottom edge portion 2b (engaged edge portion 2c) of the latching pieces 33 and 33 'by contacting the bottom edge portion 2b (engaged edge portion 2c). The overlapping position of the upper edge 3a in the vehicle vertical direction is restricted, and the parting (3a) of the mating part (2b / 3a) can be taken out only by them, and the roof lining lower edge 2b (2c) is hung. A certain degree of position regulation effect is obtained in the vehicle width direction and the vehicle front-rear direction by the engagement by the frictional force abutting against the base end portions (step portions) of the stop pieces 33, 33 '.

  Moreover, in the said embodiment, although the case where the mating part structure which concerns on this invention was implemented in the mating part (2b / 3a) of the quarter upper trim 3 and roof lining 2 adjacent to the back door opening part 10 was shown, The mating part structure according to the invention can be implemented in a mating part of interior parts other than these interior parts and interior parts adjacent to door openings other than the back door.
