関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pocket structure in an interior trim such as an automobile door trim, a rear side trim, and a luggage side trim.
The present invention relates to a pocket structure for an interior trim, which is configured by a divided body and allows a pocket back cover to be attached to one of the divided bodies to be easily and quickly attached without being restricted by an installation space.

ア３との接合を行なっている。[0005] As a recent trend, for the purpose of enhancing the aesthetics of the interior trim and the like, the interior trim composed of divided bodies, such as a door trim 1 shown in FIG. 5, is increasing. The door trim 1 is composed of an upper and lower divided body of a trim upper 2 and a trim lower 3, and ultrasonic processing is used as a method of joining the trim upper 2 and the trim lower 3. That is, as shown in FIG. 6, ultrasonic pegs 4 a are protruded from the back side of the upper edge of the trim lower 3 along the joining line between the trim upper 2 and the trim lower 3, and the inside of the mounting hole 5 of the trim upper 2 is formed. The trim upper 2 and the trim lower 3 are joined by crimping the tip of the ultrasonic peg 4a by ultrasonic welding.

リムロア３の背面側に取り付けているのが実情である。Further, the door pocket 6 has a pocket opening 3a in the trim lower 3 and a pocket back cover 7 attached to the rear side thereof. As means for attaching the pocket back cover 7 to the rear side of the trim lower 3, Ultrasonic processing is also used, and ultrasonic pegs 4b are protruded from the periphery of the pocket opening 3a of the trim lower 3, and the ultrasonic pegs 4b are inserted into mounting holes 7b provided in mounting pieces 7a on the peripheral edge of the pocket back cover 7. The pocket back cover 7 is attached to the rear side of the trim lower 3 by ultrasonically caulking the tip.

超音波加工ポイントａ，ｂの距離が近付く傾向にある。As described above, conventionally, the trim upper 2 and the trim lower 3 are ultrasonically fixed and fixed, and the pocket back cover 7 is fixed to the rear side of the trim lower 3 by ultrasonic welding. For example, when the ultrasonic processing points of the trim upper 2 and the trim lower 3 are shown in FIG. 5A and the ultrasonic processing points of the trim lower 3 and the pocket back cover 7 are shown in FIG. Due to the shape of the door pocket 6, the distance between the two ultrasonic processing points a and b tends to be short.

いのが実情である。In order to efficiently manufacture the door trim 1, it is preferable that the ultrasonic welding of the trim upper 2 and the trim lower 3 and the ultrasonic welding of the pocket back cover 7 to the trim lower 3 be performed in the same step. As shown in FIG. 7, an ultrasonic horn 8a used for an ultrasonic processing point a and an ultrasonic horn 8b used for an ultrasonic processing point b for ultrasonically fixing the pocket back cover 7 to the trim lower 3 are provided. Actually, the distance cannot be set to 70 mm or less due to the problem of interference between the horns 8a and 8b.

り、コストアップを招来しているのが実情である。Therefore, in order to manufacture the door trim 1 efficiently, the distance between the ultrasonic processing points a and b must be 7
It is necessary to simultaneously perform the ultrasonic processing on the trim upper 2, the trim lower 3, and the pocket back cover 7 with an interval of 0 mm or more. However, in actual modeling, the distance between the ultrasonic processing points a and b is about 30 mm. Therefore, the ultrasonic welding of the trim upper 2 and the trim lower 3 and the ultrasonic welding of the trim lower 3 and the pocket back cover 7 must be performed by different molds, respectively. The actual situation is that the number of processes is increased and the number of mold facilities is increased, resulting in an increase in cost.

It is an object of the present invention to provide a pocket structure in an interior trim that can complete the production in one step of the ultrasonic welding process without being restricted by the installation position of the pocket.

溶着固定されていることを特徴とする。SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, an interior trim is formed by joining and fixing trim pieces to each other by ultrasonic welding, and the trim piece is opened on one of the trim pieces. In the pocket structure of the interior trim in which a pocket is provided by attaching a pocket back cover to the back side of the pocket opening, the pocket back cover has a joint portion of the trim split body and an edge at a position closest to the trim split body on one side. The pocket back cover is fixedly fastened and the remaining edge of the pocket back cover is ultrasonically welded and fixed to the back surface of the trim divided body.
