Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the mounting structure of a trim material for an automobile, particularly a trim material disposed on the side surface of a vehicle cabin.

Generally, as shown in FIG. 1, a trim material 4 made of resin or the like is provided on the side surface of the vehicle interior of the vehicle body pillar 2, but the mounting structure of the trim material 4 to the pillar 2 is conventional. Various types are in practical use, and examples of their structures include those shown in FIGS. 2 and 3.

The pillar shown in FIG. 2 is composed of an outer panel 6 and an inner panel 8, and has flanges 10 on both sides.
and 12 are formed, and the trim material 4 disposed on the side surface of the vehicle interior of the pillar 2 has flanges 10 and 12 on both sides.
and are held together with the same seven flanges 10 and 12 by clip members 14 and 16, respectively.

By the way, in actual use, such trim material 4
Due to the structure, the component of the external force acting on the trim member 4 is small in the direction of separating the trim member 4, and the component of the external force acting on the trim member 4 is small in the direction parallel to the side surface of the vehicle interior of the pillar 2, that is, in the left-right direction in Fig. 2. Most of the force is in the direction of movement, but the external force in the horizontal direction in Figure 2 that acts on the trim member 4 and the clip member 14.16 or the clip member 14.16 and the flange 10.12 Since this method relies only on the engagement force of the clip members 14 and 16, unless the retaining force is set quite strong, it will not be able to withstand the external force acting on the trim member 4 in the left-right direction in FIG. Since it is necessary to set the clamping force to be quite strong,
On the other hand, when attaching the trim material 4 to the pillar 2, the strong clamping force of the clip members 14 and 16 deteriorates the efficiency of the attaching operation.

Moreover, the one shown in FIG. 3 has engaging parts 18 and 20 integrally formed on both sides of the trim member 4a to engage with the flanges 10 and 12 of the pillar, respectively, and does not require any clip members. However, when injection molding is used to mold the trim material 4a, the mold that defines the inner shape of the trim material 4a is divided into at least three parts in consideration of the undercut of the trim material 4a. Since the manufacturing cost is high, the inner panel 8 of the pillar 2 in the trim material 4a is first formed by vacuum forming.
It is also possible to adopt a method in which the engaging portions 18 and 20 are formed by hot bending after forming the portions along the contours, but in that case, there is also a problem that the manufacturing cost is high due to the increase in the number of man-hours.

Furthermore, in the case shown in FIG. 3, when attaching the trim material 4a to the pillar 2, it is necessary to spread the trim material 4a, and if the operator accidentally spreads the trim material 4a too much, the trim material 4a
There was a risk that it would be destroyed.

The present invention has been devised in view of the above, and includes a main body portion disposed on the side surface of the vehicle interior of the inner panel of the pillar consisting of an outer panel and an inner panel, and a thin wall portion on the side edge of the main body portion. A resin trim material having a flap part formed at an appropriate location and rotatable around the same thin wall part, and a flange formed on the pillar being sandwiched between the main body part of the trim material and the flap part. a clip member having a U-shaped cross section that engages both parts so as to hold the main body, and a stopper protruding from the back surface of the main body so as to engage with an opening formed in the inner panel; The gist of the present invention is to provide a mounting structure for an automotive trim material, characterized in that an engaging recess is formed in the main body portion and the flap portion corresponding to the flange to engage an end portion of the clip member. be.

According to the present invention, the flange is held between the main body part and the flap part of the trim material and is held by the clip member that engages with both parts, so that in actual use. When an external force is applied to the trim member, most of the force acting on the clip member is only the rotational moment about the thin wall portion generated in the flap portion due to contact with the tip of the flange.

By the way, the rotational moment is calculated by applying the same external force to the distance between a straight line parallel to the external force passing through the abutting part between the flap part and the tip of the flange and a straight line parallel to the external force passing through the thin wall part. Since the distance can be set to be extremely small or zero, the rotational moment can be made extremely small or zero.

Therefore, since the clamping force of the clip member can be set smaller than that of the clip members 14 and 16 shown in FIG. 2, it is possible to improve the work of attaching the trim material to the pillar.

Further, in the present invention, in order to prevent the flap part of the trim material from forming a so-called undercut in the injection molded product due to the flap part and the main body part, the flap part of the trim material is arranged so that the thin wall part is attached to the outside of the main body part. Even if the flap part is molded so that it is located in the opposite direction, the flap part can be rotated to the desired position after molding, so the first flap part that defines the surface of the main body part can be rotated to the desired position.
By forming the parts that define the front and back surfaces of the flap part in a second mold that defines the back surface of the main body part, no extra molds or processes are required to mold the flap part. This has the effect that the flap portion can be molded without having to do so.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 4 and 5.

In the drawings, parts that are substantially the same as those of the conventional device shown in FIGS. 1 to 3 are designated by the same reference numerals as used above, and detailed explanations thereof will be omitted.

The resin trim material 14 includes a main body part 16 disposed on the side surface of the vehicle interior of the pillar 2, and a main body part 16 formed on one side edge of the main body part 16 so as to sandwich the flange 12 of the pillar 2 between the main body part 16. It has a retaining part 20 located thereon, and a flap part 22 formed on the other side edge of the main body part 16.

Ribs 24 are formed at appropriate locations along the entire length of the trim material 14 on the surface facing the flange 12 from one side edge of the main body part 16 to the engaging part 20.
The bending rigidity is improved compared to 6.

The flap portion 22 is formed integrally and continuously with the main body portion 16 via a thin wall portion 26, and is configured to be able to rotate around the thin wall portion 26.

Further, a rib 27 is formed on the side edge of the main body 16 near the thin wall portion 26, and an engaging portion 38 is formed between the main body 16 and the flap 22 corresponding to the flange 10. .

Further, a stopper 30 is formed on the main body portion 16 and engages with an opening 28 formed on the back surface of the inner panel 8 of the pillar 2 to prevent the trim member 14 from moving in the left-right direction in the drawing.

This trim material 14 is attached to the pillar 2 first.
As shown in the figure, the engaging part 20 of the trim member 14 is engaged with the flange 12 of the pillar 2, and then, as shown in FIG. 16 to sandwich the flange 10, and finally, a material having high elasticity such as sheet metal is cut out and engaged with both the flap part 22 and the main body part 16, so that the flange 10 is sandwiched between the two parts. This is done by attaching a clip member 32 having a U-shaped cross section for holding.

According to the above configuration, in the trim material 14, the engagement part 20 is engaged with the flange 12 of the pillar 2 at one side edge, and the flap part 22 is engaged with the flange 10 at the other side edge. As a result, it will be attached to the same pillar 2.

Regarding one side edge of the trim material 14, the main body portion 16
Since the ribs 24 are formed from the engagement portion 20 to the engagement portion 20, the trim material 24 can sufficiently withstand external forces acting on the trim material 24.

Regarding the other side edge of the trim member 14, the end 40 of the clip member 32, which engages the flange 10 between the main body 16 and the flap 22, is engaged with the engaging portion 38. Since the clip member 32 is held by fitting together, when an external force is applied to the trim member 14, most of the force acting on the clip member 32 is transferred to the thin wall portion generated on the flap portion 22 due to contact with the tip of the flange 10. The rotational moment about 26 is only.

By the way, the rotational moment is determined by applying the same external force to the distance between a straight line parallel to the external force passing through the abutting part between the flap part 22 and the tip of the flange 10 and a straight line parallel to the external force passing through the thin wall part 26. is the sum of the distances, and the distance is set to be extremely small or zero, so
The rotational moment can be made extremely small or zero.

Therefore, the clamping force of the clip member 32 can be set smaller than that of the clip members 14 and 16 shown in FIG. In particular, in this embodiment, since the flap portion 22 is provided only on one side edge, the efficiency of the attachment work can be further improved.

In addition, in this embodiment, the flap portion 22 of the trim material 14 is arranged as shown in FIG. Even if the thin wall portion 26 is formed to be located outside the main body portion 16 as shown in the figure, the flap portion 22 can be rotated to a desired position after molding. By forming the portions that define the front and back surfaces of the flap portion 22 in the first mold that defines the back surface of the main body portion 16 and the second mold that defines the back surface of the main body portion 16, there is no need to create any extra material for molding the flap portion 22. This has the effect that the flap portion 22 can be formed without requiring a mold or process.

Furthermore, in the above embodiment, the groove 36 is formed at a position symmetrical to the groove 34 formed on the side surface of the vehicle interior by the clip member 32 and the main body 16 with respect to the center line of the main body 16. This has the effect of eliminating the strange feeling that the trim member 14 is attached only to one edge of the trim member 14.

In the above embodiment, the flap portion 22 of the trim material 14 is provided only on one side edge of the main body portion 16, but it is also possible to provide it on both side edges of the main body portion 16.
