Description

  The present invention relates to an automotive interior part in which a decorative member is mounted at a predetermined position on the surface of an interior trim main body. In particular, the decorative member can be replaced by a simple operation while maintaining good appearance design and mounting strength. It relates to automotive interior parts.

  FIG. 8 shows an automotive door trim 1 mounted on the indoor side of a vehicle door panel. The door trim 1 has a decorative member 3 mounted on a middle portion of a door trim body 2 formed into a desired curved surface shape. Due to the contrast effect on the appearance of the door trim main body 2 and the decorative member 3, excellent appearance performance is imparted.

  Conventionally, when the decorative member 3 becomes dirty or when the mood is changed, it is necessary to replace the entire door trim 1 in order to replace the decorative member 3 with a new one. As a countermeasure, for example, as shown in FIG. 9, the magnetic trimming force by the magnet and the metal piece is applied to the corresponding part of the door trim main body 2 and the decorative member 3, or the engagement force of the hook-and-loop fastener is applied. A configuration in which the member 3 is configured to be replaceable has also been proposed. For example, this conventional example is described in detail in Patent Document 1.

  Further, since the stable attachment strength cannot be secured by the magnetic attraction force between the magnet and the metal piece or the engaging force by the hook-and-loop fastener, for example, as shown in FIG. In order to remove the decorative member 3, it is necessary to provide a working hole 5 on the product surface.

Japanese Utility Model Publication No. 61-61222

  Thus, in the conventional door trim 1 in which the decorative member 3 is mounted at a predetermined position on the surface of the door trim main body 2, when the decorative member 3 becomes dirty or when the mood is changed, a new decorative member 3 is provided. In order to replace it, it is necessary to replace the entire door trim 1, and it has been pointed out that it involves a very troublesome work. On the other hand, as shown in FIG. 9, it has been proposed that the decorative member 3 replaceable with respect to the door trim main body 2 is held by a magnetic attractive force or a hooking force of a hook-and-loop fastener. It is not a thing. In addition, as shown in FIG. 10, when the clip 4 is used to secure the mounting strength, it is necessary to provide the working hole 5 for removing the decorative member 3 so as to appear on the product surface, which deteriorates the appearance performance. There was a drawback of making it.

  The present invention has been made in view of such circumstances, and the decoration member can be replaced with respect to the door trim main body by a simple operation, the attachment strength of the decoration member is strong, and the appearance performance is not deteriorated. It aims to provide automotive interior parts.

  In order to solve the above-mentioned problems, the present invention provides an automotive interior part in which a decorative member is mounted at a predetermined position on the surface of an interior trim main body. The decorative member has two systems of attachment mechanisms for the interior trim main body. As an attachment mechanism on one side of the attachment mechanisms, an insertion fixing structure is adopted in which the insertion piece of the decorative member is inserted into the attachment seat of the interior trim body and fixed. In addition, as a mounting mechanism on the other side, a press fixing structure is employed in which the decorative member is pressed and fixed to the interior trim body by a separate part that is fitted into the opening of the decorative member and is detachably attached to the interior trim body. The pressing and fixing force in the pressing and fixing structure acts as an urging force in the insertion direction of the insertion piece, whereby reliable support and fixing of the decorative member can be obtained.

  Here, the interior parts can be applied to door trims, rear side trims, luggage side trims, etc., and the decorative members attached to the predetermined positions on the interior parts can be expected to have a contrast effect on the product surface of the interior trim body. Thus, for example, when the interior trim body is a single resin product, it is preferable that the decorative member has a cloth appearance such as a cloth or a non-woven fabric on the product surface.

  Accordingly, the interior trim main body is a synthetic resin injection molded body, a resin press molded body of a mold press molded body, or a laminated structure in which a synthetic resin sheet is laminated on the surface of the resin single body. On the other hand, as a decorative member, a laminated structure in which a skin such as a cloth or a nonwoven fabric is laminated on the surface of a resin base material is used.

  Furthermore, as a decorative member, for example, the upper half portion has a substantially vertical surface shape so as to occupy from the inscribed portion of the door trim to the upper surface of the armrest, and the lower half portion has a substantially horizontal surface shape projecting indoors. As such, an inscribed member or the like set to a three-dimensional shape is suitable. Of the two types of attachment mechanisms for attaching the decorative member to the interior trim body, as one of the attachment mechanisms, the insertion piece inserted into the attachment seat of the interior trim body extends obliquely downward from the back surface of the ornament member. The insertion piece is inserted into the mounting seat to fix the decorative member. Further, as the attachment mechanism on the other side, a pressing and fixing structure is employed in which when a separate part such as a pull handle is attached to the door trim body, the decorative member is pressed against the interior trim body by the pull handle. And this pressing force urges the insertion piece on one side in the insertion direction. Therefore, since the decorative member inserts and attaches the insertion piece and is pressed and held by a separate part, the decorative member can be reliably prevented from falling into the indoor side.

  Next, a method of attaching the decorative member to the interior trim main body will be described. The insert piece of the decorative member is moved obliquely downward with respect to the mounting seat of the interior trim main body, and the insert piece is attached to the interior trim main body. Insert the other part such as a pull handle into the opening of the decorative member, and fix the pull handle to the bracket of the interior trim body with screws. A load is applied, and the decorative member does not fall into the indoor side by applying the attachment force of the lower portion to the upper portion.

  And when the decorative member gets dirty or is replaced with a new one to change the mood, loosen the screws of other parts such as the pull handle, remove the other parts, and release the downward stress of the lower part of the decorative member After that, if you put your hand in the opening for attaching the separate part that appeared by removing the separate part and pull up the entire decorative member diagonally upward, pull out the insertion piece from the mounting seat of the interior trim body, The decorative member can be easily removed from the interior trim body.

  As described above, according to the configuration of the automobile interior part according to the present invention, the structure for attaching the decoration member to the interior trim main body includes the decoration member after inserting the insertion piece of the decoration member into the interior trim main body. A separate member is attached to both of the interior trim bodies, and the decorative member can be reliably attached to the interior trim body by applying the pressing force when the separate parts are attached as a biasing force in the insertion direction of the insertion piece. Therefore, it does not come off easily, a strong mounting strength can be obtained, and a work hole for removal does not appear on the product surface, which is preferable in terms of appearance. Also, to replace the decorative member, you can easily remove the decorative member from the interior trim body by removing the separate parts, releasing the holding stress applied to the decorative member, and pulling up the decorative member diagonally upward. The decorative member can be exchanged with a simple operation.

  As described above, the automotive interior part according to the present invention has a configuration in which the decorative member is detachably fixed to a predetermined position on the surface of the interior trim main body through two systems of attachment mechanisms, and the attachment mechanism on one side is The insertion member is provided with an insertion piece, and the insertion piece is inserted into the mounting seat of the interior trim main body, and the insertion fixing structure for attaching the decoration member is adopted. The attachment mechanism on the other side includes the decoration member and the interior trim. A separate fixing part is attached to the main body, and a pressing and fixing structure is used to press the decorative member against the interior trim main body by the pressing force when the separate part is attached. Since the mounting mechanism of the system is arranged, it can be replaced with simple work, the workability at the time of replacement can be improved, and once installed, a strong mounting strength can be secured, and Since work holes it does not appear to the outside, an effect of excellent appearance properties and attachment strength.
