DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bracket mounting structure for mounting a clip on a molded ceiling for an automobile.

[0002]

2. Description of the Related Art Conventionally, the inside of a roof panel of an automobile is covered with a roofing, which is an interior material. Recently, many automobiles have been manufactured in which a front part of the roofing is formed by a molded ceiling so that a sun visor can be stored in a good shape. Have been.

The above-mentioned molded ceiling is usually fixed to a vehicle body frame or the like using a clip. Various mounting structures for the molded ceiling and the clip have been proposed so that the clip is not exposed on the surface of the molded ceiling.

[0004] For example, in Japanese Utility Model Laid-Open Publication No. 2-2152, an end of a molded ceiling is sandwiched between a pillar garnish attached to an inner panel and a pillar garnish attached to the inner panel by a pillar garnish fixing clip having a triangular head. Pillar connection structures have been proposed.

[0005] For example, in Japanese Utility Model Laid-Open No. Hei 5-17210, a non-woven fabric with hot melt is adhered to a clip mounting position of a resin base material, a clip mounting seat is bonded to the non-woven fabric, and a clip is mounted on the clip mounting seat. There has been proposed a clip mounting structure for mounting a clip.

As still another method, as shown in FIG. 3, a bracket c is attached to a back surface of a molded ceiling a with an adhesive b, and a clip d is attached to the bracket c. ing.

[0007]

However, in the case where the molded ceiling is mounted via the pillar garnish disclosed in the former publication, the molded ceiling and the pillar garnish must be assembled at the same time. Since the load is received by the triangular head of the pillar garnish fixing clip, there is a problem that the clip is easily detached.

[0008] In the clip mounting structure disclosed in the latter publication, the process for mounting the clip mounting seat is complicated, which increases man-hours and costs, and the clip is easily detached from the clip mounting seat, resulting in poor workability. There is also a problem.

On the other hand, in the bracket mounting structure shown in FIG. 3, the mounting strength of the bracket c is determined by the performance of the adhesive b, and oil and the like adhere to the bracket c when the bracket c is bonded to the molded ceiling a. In this case, sufficient adhesive strength cannot be obtained, so the bracket c
There is a problem such as easy falling off.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a bracket mounting structure for a molded ceiling for automobiles which is easy to mount and has high adhesive strength.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a bracket mounting structure for a molded ceiling for automobiles in which a bracket for attaching a clip to a base material of the molded ceiling is attached. A plurality of cut-and-raised pieces are cut and raised, and a portion of the adhesive is protruded from the slit formed by the cut and raised to the upper surface side of the mounting portion, thereby forming a raised portion of the adhesive, and forming the raised portion of the adhesive. The base of the clip is sandwiched between locking portions bent from the mounting portion.

[0012]

According to the above construction, the adhesive force of the bracket is greatly improved by the anchor effect of the raised portion of the adhesive protruding from the upper surface of the mounting portion.

In addition, since the base of the clip is pressed against the engaging portion by the elasticity of the raised portion by using the rubber-based adhesive, there is no play between the clip and the bracket.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to the drawings shown in FIGS.

FIG. 1 is a perspective view of a bracket attached to the back surface of a molded ceiling, and FIG. 2 is an enlarged sectional view taken along line AA of FIG.

In these figures, reference numeral 1 denotes a molded ceiling, which is composed of a base material 1a integrally formed of resin and a skin 1b adhered to the vehicle inner surface of the base material 1a.

Reference numeral 2 denotes an adhesive 3 on the substrate 1a of the molded ceiling 1.
And is formed of a metal plate.

The bracket 2 has a rectangular mounting portion 2.
and a locking portion 2b bent substantially U-shaped from one side of the mounting portion 2a. The mounting portion 2a has a plurality of cut-and-raised pieces 2c parallel to the short side of the mounting portion 2a.
Are formed.

These cut-and-raised pieces 2c are formed by cutting and raising one side of a slit 2d formed in the mounting portion 2a. When the mounting portion 2a of the bracket 2 is bonded with the adhesive 3, a part of the adhesive 3 is formed. Is each slit 2d
As shown in FIG. 2, the protruding portion 3a protrudes to the upper surface side of the mounting portion 2a to form a substantially mountain-shaped raised portion 3a.

An insertion hole 2e into which the base of the clip 4 is inserted is opened in the bent portion of the locking portion 2b. The base of the clip 4 inserted through the insertion hole 2e is connected to the locking portion 2b and the adhesive. 3 between the raised portions 3a.

Next, the operation will be described. A plurality of brackets 2 are bonded to predetermined portions of the base material 1a of the molded ceiling 1 by using an adhesive 3 having elasticity even after hardening such as rubber. When the mounting portion 2a of the gracket 2 is adhered, a part of the adhesive 3 protrudes from the slit 2d of the mounting portion 2a to form a mountain-shaped raised portion 3a on the upper surface side of the mounting portion 2a as shown in FIG.

When the base of the clip 4 is inserted into the insertion hole 2e after the adhesive 3 has hardened, the base of the clip 4 is clamped between the engaging portion 2b and the raised portion 3a as shown in FIG. As a result, the clip 3 does not fall off the bracket 2 and the base of the clip 4 is pressed against the locking portion 2b from below by the elasticity of the raised portion 3a by using a rubber-based adhesive. There is no play between the bracket 4 and the bracket 2.

The clearance of the seat of the clip 4 can be freely adjusted by adjusting the height of the cut-and-raised piece 2c formed by cutting and raising the mounting portion 2a.

[0024]

As described in detail above, according to the present invention, since a plurality of cut-and-raised pieces are cut and raised at the mounting portion of the bracket, when the bracket is bonded to the base material of the molded ceiling, a part of the adhesive is removed. Since the protrusion protrudes from the slit toward the upper surface of the mounting portion, the bracket can be firmly bonded to the base material by the anchor effect of the protruding adhesive.

Thus, there is no fear that the bracket will fall off even when a large force or vibration acts on the molded ceiling, and the adhesive that has protruded from the slit forms a swelling portion, so that the base of the clip and the locking portion are interposed. The clip does not come off from the bracket during assembly of the molded ceiling, and workability during assembly is very good.

If a rubber-based adhesive is used as the adhesive,
Because the base of the clip is pressed against the locking piece due to the elasticity of the raised part and no backlash occurs, the molded ceiling does not rattle due to vibration etc. after assembly, and by forming multiple cut and raised pieces in the mounting part Since the rigidity of the bracket increases, the mounting strength of the molded ceiling also increases.
