Description

  The present invention relates to a clip mounting seat structure for mounting a clip for mounting an interior part of an automobile to a vehicle body.

  When installing interior parts such as door trims and body side trims to the vehicle body such as an inner panel of an automobile, a clip mounting seat is formed at a predetermined position on the back of the interior part, and the clip mounted on the clip mounting seat is attached to the vehicle body. This was done by fitting into the formed clip mounting hole.

  Usually, the clip mounting seat is formed at a plurality of locations on the back surface of the interior part, so that the clip is attached to each, and the interior component is attached at a plurality of locations on the vehicle body (see Patent Document 1).

Many of the clip mounting seats formed on the back surface of the interior part are formed on the panel surface portion of the interior part. Therefore, in some cases, for example, there is a case where it is unavoidable to form a flange portion that rises with respect to the panel surface portion of the interior part (see Patent Document 2).

  The clip mounting seat X is intended to alleviate the impact at the time of a side impact on the occupant by buckling when the occupant comes into contact with the interior part a in the event of a side collision of an automobile or the like.

  For this reason, although not shown, the rising wall portion d is connected and formed only to the flange portion c so as to have a predetermined gap with respect to the panel surface portion b.

  However, in the above-described prior art, even if the rising wall portion d is formed with a predetermined gap with respect to the panel surface portion b, the clip mounting seat X is still formed by connecting the clip seating portion e to the flange portion c. Therefore, it must be said that the structure has high rigidity and is difficult to buckle in the case of a car crash or the like.

  Therefore, in view of such points, the present invention is for mounting an automotive interior part in which a clip mounting seat formed on the flange part and / or panel surface part of the interior part is formed into a shape that easily buckles in the event of a side collision of the automobile. It aims at providing the clip seat structure to be used.

  In order to solve such a problem, the clip mounting seat structure according to the present invention is a clip mounting seat structure formed on the interior part in order to mount a clip for mounting the interior part on the body of an automobile, A rising wall portion is formed on a flange portion that is raised with respect to a panel surface portion of a component, a clip seating portion is formed at a tip of the rising wall portion, and a part or all of the clip seating portion is formed on the flange portion. It is characterized by being formed separately from the above.

  According to the present invention configured as described above, since the clip seating part is separated from the flange part, the clip mounting seat can be easily buckled in the event of a side collision of an automobile, etc. Can be protected more safely.

  Next, embodiments according to the present invention will be described with reference to the drawings.

  FIG. 1 is a front view of a door trim, which is an interior part adopting an embodiment of the present invention, drawn from the passenger compartment side. FIG. 2 is a side view of a clip mounting seat formed near the flange portion of the door trim in FIG. FIG. 3 is an enlarged perspective view of the main part, FIG. 3 is an enlarged perspective view of the main part drawn from the other side of the clip mounting seat formed in the vicinity of the flange part of the door trim in FIG. 1, and FIG. It is sectional drawing.

  In the figure, a door trim 1, which is an interior part, is formed so that an armrest portion 2, an inside handle portion 3, a pocket portion 4 or a speaker grill portion 5 are formed on a panel surface portion 1A and an outer peripheral portion of the panel surface portion 1A. The flange portion 1B is generally configured.

  The door trim 1 is configured to be attached to the vehicle body panel by fitting the clip 10 into a clip mounting hole of a vehicle body panel (not shown). A clip mounting seat 6 is formed.

  Of the clip mounting seat 6, for example, the clip mounting seat 6-1 formed at a corner where the panel surface portion 1A and the flange portion 1B intersect with each other is formed to bridge the panel surface portion 1A and the flange portion 1B. A pair of rising wall portions 7 and 7 spaced apart from each other and a clip seating portion 8 formed so as to extend along the panel surface portion while bridging the leading end portions of the rising wall portions 7 and 7 are configured.

  The clip seating portion 8 includes a clip mounting hole 8a that is opened substantially at the center and a guide groove 8b that guides the clip to the mounting hole 8a.
