Description

  The present invention relates to an interior part for an automobile such as a luggage side trim provided with a belt tongue fixing portion as means for fixing a belt tongue of a seat belt, and in particular, a resin sink mark near the belt tongue insertion guide. It is suitable for preventing the insertion defect of a belt tongue by raising the rigidity of the insertion guide, without producing the appearance defect of the trim main body by this.

  Conventionally, a seat belt of an automobile is provided with a belt tongue at its tip (see, for example, Patent Document 1). There is also known an automobile interior part provided with a belt tongue fixing portion as means for fixing such a belt tongue in a predetermined position when the seat belt is not used.

  FIG. 7 is a sectional view of a belt tongue fixing portion in a conventional automobile interior part (specifically, a luggage side trim disposed on the side of a vehicle luggage room).

  Referring to FIG. 7, a conventional automobile interior part 100 is inserted into a trim main body 2 formed into a required shape by a resin, a belt tongue insertion opening 3 opened in the trim main body 2, and a belt tongue insertion opening 3 And a belt tongue fixing portion 4 for fixing the belt tongue T of the seat belt S.

  By the way, the belt tongue fixing portion 4 in the conventional automobile interior part 100 includes the metal clip 6 for detachably locking the belt tongue T inserted into the belt tongue insertion opening 3 and the support member 7 for supporting the metal clip 6. The insertion guide 10 guides the insertion of the belt tongue T. The insertion guide 10 has a structure in which the rib GR is integrally formed on the back surface of the upper wall 22 of the trim main body 2.

  However, in the conventional automobile interior part 100 described above, as a specific structure of the insertion guide 10, as described above, a structure in which the rib GR is integrally formed on the back surface of the upper wall 22 of the trim main body 2 is adopted. . Therefore, when molding the trim main body 2 with a mold using a heat-melted resin, there is a problem that appearance defects of the trim main body 2 due to sinking of the resin in the vicinity of the insertion guide 10 easily occur.

  As a means for solving the problem of the appearance defect as described above, a method of thinning the rib GR can be considered. However, in such a method, the rigidity of the rib GR decreases due to the thinning of the rib GR, and the frictional resistance or the like at the time of guiding the belt tongue T by the rib GR causes breakage such as breakage of the rib GR. There is a problem that the insertion failure of the belt tongue is likely to occur, for example, the insertion locus of T is shifted to the outside of the metal clip 6, and the belt tongue T can not be inserted by aiming at the metal clip 6.
