Description

  The present invention relates to an automotive interior part equipped with an inner seal that slides and seals a window glass, and in particular, a covering projection that protrudes toward the panel side from the waist part corner line of the trim body is set. The present invention relates to an interior part for an automobile that can improve the appearance appearance by covering the head of an inner seal with a convex part for use, and further reduce the manufacturing cost by eliminating the waist garnish.

  FIG. 11 is a perspective view of the door trim 1 provided on the indoor surface side of the door panel of the vehicle as viewed from the indoor side. The door trim 1 is configured by joining and fixing the upper and lower divided parts of the door trim upper 2 and the door trim lower 3. Has been. The door trim upper 2 is composed of a laminated structure in which a skin 2b is adhered to the surface of a resin core material 2a having shape retention, and the door trim lower 3 takes into account the contrast effect on the appearance with the door trim upper 2 It consists of a single resin product.

  The door trim 1 is provided with a door inner seal 4 for slidingly sealing the door window glass. Recently, the door inner seal 4 is a seal for slidingly sealing the door window glass on one side of the base plate 4a. A lip 4b is formed, and a panel fitting portion 4c to be fitted to the door panel 5 is formed on the other side. Further, a covering convex portion 6 having a dimension indicated by d is formed from the waist corner line A of the door trim upper 2 to the upper end of the base plate 4a of the door inner seal 4 so that the attachment portion of the door inner seal 4 is not conspicuous in appearance. ing. For example, Patent Document 1 discloses a conventional example in which the door inner seal 4 is sealed with the covering projection 6 of the door trim body. Conventionally, in order to seal the door inner seal 4, it is the actual situation that a separate waist garnish 7 is welded and fixed to the inner surface of the resin core material 2 a in the door trim upper 2 by ultrasonic welding or the like. The reason is that, in order to integrally mold the flange for attaching the door inner seal 4 to the resin core material 2a, the amount of undercut is too large and molding becomes difficult.

Japanese Utility Model Publication No. 4-59512

  As described above, in the door trim 1 equipped with the door inner seal 4, in order to conceal the upper end of the base plate 4 a of the door inner seal 4, the waist side corner line A of the door trim upper 2 is directed downward toward the panel side. And the covering convex portion 6 and the flange for holding the door inner seal 4 are integrally formed with the door trim upper 2 because the undercut portion becomes too deep and difficult to form. Therefore, as shown in FIG. 12, the fact is that a separate waist garnish 7 is attached to the door trim upper 2. Therefore, since the waist garnish 7 is required, it has been pointed out that the number of parts is large, the mounting man-hour is increased, and the weight of the product is increased.

  The present invention has been made in view of such circumstances, and in an automotive interior part having an inner seal attached thereto, such as a door trim equipped with a door inner seal, the downward direction from the corner line of the waist of the trim body. By forming the convex part for covering and covering the head of the base plate in the inner seal with this convex part for covering, the outer appearance is enhanced and the inner seal is applied to the trim body without requiring a separate waist garnish. An object is to provide an automobile interior part that can be manufactured at low cost by being directly attached.

  In order to solve the above-described problems, the present invention provides an automotive interior part equipped with an inner seal for slidingly sealing a window glass, the covering convex covering the head of the base plate of the inner seal attached to the trim body. In the automotive interior part in which the portion is set to the trim body, the covering convex portions are provided with a plurality of vertical ribs provided on the inner surface of the trim body at appropriate intervals along the longitudinal direction of the inner seal; The inner seal is supported by a support piece that is connected to the lower edge of the vertical rib and extends downward from the horizontal rib.

  Here, as interior parts for automobiles, it can be applied to door trims (including door trims mounted on the interior side of sliding doors), luggage side trims, etc., and all interior parts equipped with inner seals that slide and seal window glass. Applicable to. Further, in the case of a door trim, it can be applied to an integrated door trim, but can be applied to a split type door trim configured by joining and fixing two upper and lower divided bodies including a door trim upper and a door trim lower. .

  Furthermore, the inner seal attached to the trim body has a flexible seal lip formed on one side (the door window glass facing surface) of the base plate that is abutted and fixed to the mounting surface of the trim body. On the other side, a panel insertion part with an inverted U-shaped cross section connected to the lower end of the base plate is formed. The panel insertion part is inserted into the upper edge flange of the vehicle body panel, and between the base plate and the panel insertion part. It can be firmly attached by clamping and fixing the support piece of the trim body.

  Next, the upper side of the interior trim main body is configured to prevent the inner seal from being exposed to the outside by providing a covering convex portion protruding to the panel side so as to cover the head of the inner seal. In particular, in order to reduce the amount of undercut at the time of molding, as the covering convex portion, a large number of vertical ribs formed on the inner surface of the trim body at appropriate intervals along the longitudinal direction of the inner seal, A support piece configured to connect the lower edge of the rib and support the base plate of the inner seal is formed to extend downward from the horizontal rib. That is, support pieces are formed to extend downward from the lateral ribs at three or five locations along the longitudinal direction of the inner seal.

  The trim body is formed by sticking the skin on the surface of the resin core material, and even in the covering convex portion, the portion where the support piece is set passes through the edge of the vertical rib and the edge of the horizontal rib. The skin extends to the support piece, and the skin where the support piece is not set is wound on the lower surface of the lateral rib.

  Therefore, according to the automotive interior part according to the present invention, when the trim body is manufactured, the vertical rib and the horizontal rib constituting the covering convex portion can be easily obtained by opening the groove portion in the core die in the molding die. In addition, since the vertical rib can be integrally formed on the inner surface of the trim body, only the length of the support piece becomes the undercut size. Therefore, the support piece which becomes the attachment part of the inner seal can be integrally formed integrally with the resin core material of the trim main body. Therefore, the conventional waist garnish can be abolished, and there are effects such as a reduction in the number of parts, a reduction in the number of mounting steps, and a reduction in weight.

  As described above, the automobile interior part according to the present invention is an interior part equipped with an inner seal, and is a panel facing downward from the waist line of the trim body in order to hide the head of the base plate in the inner seal. A covering convex part facing to the side is formed, and this covering convex part is composed of a plurality of vertical ribs formed on the inner surface of the trim main body and a horizontal rib connecting the lower edges of the vertical ribs, and supports the inner seal. The short support piece is configured to extend downward from the lateral rib. Therefore, since the vertical and horizontal ribs can be formed by clamping the mold, the amount of undercut is small, and the inner seal mounting part can be formed integrally with the trim body, thus eliminating the conventional waist garnish. It is possible to reduce the number of parts and the number of mounting steps, and to reduce the weight by eliminating the waist garnish.

  First, based on FIG. 1 thru | or FIG. 3, the structure of the automotive door trim 10 to which the automotive interior component which concerns on this invention is applied is demonstrated. First, the door trim 10 is configured by joining and fixing the upper and lower divided parts of the door trim upper 20 and the door trim lower 30, and the door trim upper 20 and the door trim lower 30 constitute a door trim main body, with respect to the door trim main body. Various functional parts are attached to form a door trim 10. For example, an inside handle escutcheon 11 is attached to the door trim upper 20, and an armrest 12 on which an occupant rests with an elbow resting at the approximate center of the surface of the door trim lower 30 is installed, and equipment can be accommodated below the armrest 12. A door pocket 13 is provided, and a speaker grille 14 is formed integrally with the door trim lower 30 or separately on the front side of the door pocket 13.

  Further, as shown in FIGS. 2 and 3, a door inner seal 40 as a seal member for slidingly sealing the door window glass 15 is attached to the door trim upper 20. By the way, this invention makes it a subject to attach this door inner seal 40 simply and cheaply and with good appearance, and therefore, the configuration of the door trim upper 20 has been devised. The configuration of the door inner seal 40 will be described with reference to FIGS. First, the door inner seal 40 includes a long base plate 41 that is in contact with and supported by the door trim upper 20, and a seal lip 42 that is in sliding contact with the door window glass 15 is formed on one side of the base plate 41. At the same time, the upper edge 41a of the base plate 41 is covered with the door trim upper 20 and is not exposed to the outside, and the trim / panel mounting portion 43 is integrated with the lower edge 41b of the base plate 41. The trim panel mounting portion 43 is set to a shape having a trim groove 43a that opens upward and a panel groove 43b that opens downward, and the door trim upper 20 is inserted into the trim groove 43a. The door inner seal 40 is firmly attached to both the door panel 16 and the door trim upper 20 by inserting the door panel 16 into the panel groove 43b. Therefore, even if the raising / lowering operation of the door window glass 15 is repeated frequently, there is no backlash and a smooth sealing action can always be exhibited.

  Next, the configuration of the door trim upper 20 on the side where the door inner seal 40 is attached will be described. The door trim upper 20 is configured by attaching a skin 22 to the surface of the resin core material 21 and is formed into a required shape by an injection molding method described later. And in order to coat | cover the upper edge 41a of the baseplate 41 of the door inner seal 40, and to improve appearance, it is for coating | covering which protrudes toward the door window glass 15 side below the waist part corner line A in the door trim upper 20. In the type in which the convex portion 23 is set, and the door inner seal 40 is attached so as to be inserted into both the door panel 16 and the door trim upper 20, when the upper edge 41 a of the base plate 41 is exposed to the outside, undulation, meandering, etc. However, in the present invention, the covering projections 23 effectively solve the appearance problems. In order to keep the appearance of the present invention good and to manufacture at a low cost, the covering convex portion 23 is composed of a combination of the vertical ribs 24 and the horizontal ribs 25, and extends downward from the edges of the horizontal ribs 25. The base plate 41 of the door inner seal 40 is abutted and supported by a support piece 26 extending to the door.

  The configuration of the door trim upper 20 will be described with reference to an external view of the resin core material 21 shown in FIG. 4 and sectional views of FIGS. 5 and 6. First, as shown in FIG. 4, the resin core material 21 is arranged along the longitudinal direction of the door inner seal 40 so that the covering convex portion 23 can be formed toward the lower side of the waist corner line A in the door trim upper 20. A large number of vertical ribs 24 are integrated with the inner surface of the resin core material 21 at appropriate pitch intervals, and the horizontal ribs 25 are integrated so as to connect the lower edges of the vertical ribs 24. Further, a support piece 26 having an appropriate width dimension is provided on a predetermined portion of the horizontal rib 25 so as to extend downward. The support piece 26 extends along the length of the horizontal rib 25 such as three or five. They are formed at appropriate intervals. In consideration of the mold structure, a combination of the vertical ribs 24 and the horizontal ribs 25 is employed so that the covering convex portion 23 does not have an undercut structure. In addition, a contact rib 26 a that can stably insert and support the door inner seal 40 is formed on the back side of the support piece 26.

  The material for the resin core material 21 can be appropriately selected from a wide range of resins. Usually, those that can be preferably used include polyethylene resins, polypropylene resins, polystyrene resins, polyethylene terephthalate resins, polyvinyl alcohol resins, vinyl chloride resins, polyamide resins, polyacetal resins, polycarbonate resins, ionomer resins, Examples include acrylonitrile / butadiene / styrene (ABS) resin. Further, as the skin 22, a fabric sheet such as a woven fabric or a nonwoven fabric, a thermoplastic resin sheet such as a TPO (thermoplastic olefin) sheet or a PVC sheet, or a polyethylene foam or a polypropylene foam on the back surface of the fabric sheet or the thermoplastic resin sheet. A laminated sheet material lined with a cushion layer such as polyurethane foam is used. As shown in FIGS. 5 and 6, the skin 22 has a support piece 26 that supports the door inner seal 40. In the region where the support piece 26 is notched, the front end portion of the skin 22 is adhesively fixed to the lower surface of the lateral rib 25 as a winding piece 22b. Therefore, it is necessary to form a slit in advance at the boundary between the sandwiching piece 22a and the winding piece 22b of the skin 22.

  Next, the molding process of the resin core material 21 in the door trim upper 20 will be described with reference to FIGS. First, a molding die 50 for molding the resin core material 21 in the door trim upper 20 includes a cavity mold 51, a core mold 52, and a slide core 53. The mold clamping of the cavity mold 51 and the core mold 52 is performed. At this time, the resin core material 21 in the door trim upper 20 is formed into a required shape by injecting and filling molten resin into a cavity formed between the two. At this time, with respect to the vertical ribs 24 and the horizontal ribs 25 constituting the covering convex portion 23, a large number of groove portions 52a are formed in the core mold 52 at appropriate pitch intervals, and a large number of vertical ribs 24 corresponding to the groove portions 52a are formed. Form. Therefore, since the vertical rib 24 can be integrally formed by drilling the groove 52 a in the core mold 52, the undercut portion is formed by the slide core 53 only by the support piece 26 integrated with the lateral rib 25. Therefore, the slide amount corresponding to the dimension indicated by L in FIG. 7 is sufficient, and as shown in FIG. 8, the mold can be easily removed after molding.

  Accordingly, since the support piece 26 can be easily integrally formed when the resin core material 21 is formed in the door trim upper 20, there is no need for a separate member such as a conventional waist garnish, and the number of parts and the number of mounting steps are greatly reduced. The cost can be reduced, and it is not necessary to attach a waist garnish or the like separately. Therefore, there is an advantage that weight increase can be avoided and weight reduction can be promoted.

  As described above, in the above-described embodiment, in order to enhance the appearance appearance of the attachment portion of the insertion type door inner seal 40, the covering convex portion 23 is formed by the combination of the vertical rib 24 and the horizontal rib 25, and the undercut structure is formed. However, in the modified example shown in FIGS. 9 and 10, the joint portion between the armrest 60 and the door trim lower 70 that supports the armrest 60 is provided. In this configuration, the present invention is applied. The armrest 60 and the door trim lower 70 are not flush with the product surface, but are set with a level difference indicated by D in FIG. Regarding the setting of the step D, as shown in FIG. 10, the armrest 60 is configured by attaching a skin 62 to the surface of the resin core 61, and a combination of the vertical rib 63 and the horizontal rib 64 when the resin core 61 is molded. By adopting the structure, the dimension adjustment of the step D can be easily performed. Accordingly, it is possible to satisfactorily adjust the appearance, such as setting the level difference of the mating portion without causing an increase in weight.

  Furthermore, since the skin 62 in the armrest 60 can be adhered and fixed over a wide range to the lower surface of the lateral rib 64 via the edge of the vertical rib 63, a large wrapping dimension of the skin 62 can be secured, and the adhesive strength of the skin 62 can be secured. Can be increased.

  Although the embodiment of the present invention is applied to the door trim 10 mounted on the indoor surface side of the door panel of a general vehicle, an inner seal that slides and seals the window glass is inserted and supported, such as a sliding door trim and a luggage side trim. It can be applied to all types of interior parts.
