Description

[Detailed Description of the Invention] << Industrial field of application >> The present invention relates to a joint structure for an automobile interior part, and in particular, a gap is not generated at a joint portion
The present invention relates to a joint structure for automobile interior parts with improved aesthetics.

<< Prior Art >> For example, as shown in FIG. 3, at the joint between the rear side trim 1 and the rear pillar trim 2, a gap is generated in the step due to the deformation of the rear side trim 1 during the molding. A method of wrapping a rear pillar trim 2 on the back surface side of the trim 1 and using a co-clamping clip 3 to co-clamp the rear side trim 1 and the rear pillar trim 2 together is performed.

Further, the deformation preventing bracket 4 is attached to the rear side trim 1.
There is also a measure to fix it on the back surface of the product by ultrasonic welding or the like.

Although not shown, a rear surface of the rear side trim 1 is also provided with a position regulating bracket having a stopper mechanism that comes into contact with the vehicle body panel.

<< Problems to be Solved by the Invention >> As described above, in the joint portion of the interior parts such as the rear side trim 1, the rear pillar trim 2 and the like, the co-fastening clip 3 is used in order to prevent a gap from being generated therebetween. In addition, since the deformation preventing bracket 4 is required, it is pointed out that the material cost is high, the number of assembling steps is large, and the cost is significantly increased.

Furthermore, since the co-clamping clip 3 appears on the surface, it has been pointed out that the appearance is poor and the design is deteriorated.

This invention was made in view of such circumstances,
It is an object of the present invention to provide a well-structured and inexpensive joint structure for a joint portion of an automobile interior part.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a joint structure for automobile interior parts, wherein interior automobile parts mounted inside a vehicle body panel are joined and fixed to each other via a bracket. The bracket is attached to the rear surface of the interior component on one side, and the rear surface of the bracket is integrally provided with stopper ribs extending in the vertical and horizontal directions, the leading edge of which abuts against the vehicle body panel. It is characterized in that a locking claw for locking the insertion piece formed at the end of the interior component on the side is formed.

<Operation> As is apparent from the above configuration, the bracket attached to the rear surface of the interior component on one side is integrally formed with the stopper rib that extends in the vertical and horizontal directions on the rear surface side and the front edge of which is in contact with the vehicle body panel. Since the stopper ribs are used to increase the rigidity against external force applied to the interior parts, a separate position regulating bracket is not required.

Furthermore, because the locking claw formed on the bracket and the insertion piece provided on the other interior component are locked,
Unlike the conventional case, the co-clamping clip is not exposed on the product surface, and the appearance is also preferable.

<< Embodiment >> An embodiment of a joint structure for an automobile interior component according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a view in which the present invention is applied to a joint structure of a rear side trim and a rear pillar trim. In the drawing, a rear side trim 10 made of a resin molded body and a rear pillar trim 20 made of a resin molded body are also referred to as a bracket 30. It is joined and fixed via.

More specifically, the bracket 30 has a rib for stopper having a reinforcing function and a stopper function for the vehicle body panel.
31 is integrally provided and this bracket 30
A locking claw 32 is formed on the side surface of the.

The locking claw 32 is used for the rear pillar trim on the other side.
Insert the insert piece 21 formed at the end of 20 into the rear side trim 10
The rear side trim 10 and the rear pillar trim 20 are joined by being inserted and fixed between the rear surface of the rear side and the locking claw 32 (see FIG. 2).

As described above, the bracket 30 used in the present invention is provided with the stopper rib 31.
Has a stopper function and a reinforcing function for accurately positioning the rear side trim 10 with respect to the vehicle body panel, and further,
Since the locking claw 32 has three functions such as joining with the rear pillar trim 20, three parts, that is, a reinforcing bracket, a positioning bracket, and a co-clip are required as in the conventional case. Without having to do so, the number of parts can be greatly reduced, and the number of mounting steps can be reduced, so that there is an advantage that a significant cost reduction can be expected.

Further, the insertion piece 21 formed at the end of the rear pillar trim 20 is formed one step lower through the step portion 21a,
As shown in FIG. 2, when the rear side trim 10 and the rear pillar trim 20 are joined together, the rear side trim 10 and the rear pillar trim 20 are substantially flush with each other, so that a sense of unity can be obtained and the surfaces can be fastened together. Since another member such as a clip for use is not exposed, it has an advantage that the appearance is very good and it can greatly contribute to the improvement of the aesthetics of the room.

<< Advantages of the Invention >> As described above, the joining structure of the automobile interior parts according to the present invention has the following special effects.

According to the present invention, the rear surface of the bracket is provided with a stopper rib that extends in the vertical and horizontal directions, the front end edge of which is in contact with the vehicle body panel, and the insert piece of the interior component on the other side is locked by the locking claw. Because of this structure, the number of parts can be significantly reduced and the number of mounting steps can be greatly reduced compared to the structure that conventionally requires three parts of a reinforcing bracket, a positioning bracket, and a joint fastening clip. This has the effect of significantly reducing costs.

According to the present invention, the bracket is fixed to the back surface of the interior part on one side, and the insertion piece provided on the interior part on the other side is sandwiched between the locking claws of the bracket. The fastening clip does not appear on the surface of the product, and it has a very good appearance and has the effect of greatly improving the design.
