JPH1148874A - Head lining mounting structure for sunroof car - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a clearance deteriorating outward appearance from producing between a sunroof unit and a head lining even if a component size error exists, by integrally bending and forming a lap part which covers from each upper end of a front end and a rear end to ends of the sunroof unit corresponding to them. SOLUTION: Because a clearance B between a front end 14 and a corresponding end 16 is larger than lap length A of a lap part 15, when a head lining 7 is mounted on the lower side of a sunroof unit 4, first the head lining 7 is slid backward by rear side clearance B. Then, because the front end of the front lap part 15 is located backward of the corresponding end 16, the lap part 15 can be placed on the corresponding end 16. In the condition that the front lap part 15 is loaded on the corresponding end 16, when the head lining 7 is slid forward until the front end 14 hits the corresponding end 16, the rear lap part can be placed on the rear corresponding end.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 denotes a roof panel of an automobile, and an upper opening 2 is formed in the center of the roof panel. A sunroof lid 3 that slides rearward is provided in the upper opening 2.

Near the front end and the rear end of the upper opening 2,
A sunroof unit 4 for sliding the sunroof lid 3 is provided. Since the structure near the front end and the rear end of the upper opening 2 is substantially the same, the structure near the front end will be described below as a representative.

On the lower surface of the sunroof unit 4, an upper dual lock 5 as one fastener member is provided by a double-sided adhesive tape 6.

Below the sunroof unit 4, a head lining 7 is attached. This head lining 7 is composed of an upper thermoplastic resin layer 8 and a lower skin layer 9. On the upper surface of the head lining 7, a lower dual lock 12 as the other fastener member is provided via a bracket 10 and a double-sided adhesive tape 11. The headlining 7 is attached to the sunroof unit 4 from below by engaging the lower dual lock 12 with the upper dual lock 5 of the sunroof unit 4.

The front end 14 of the lower opening 13 of the head lining 7 is formed to rise at a predetermined inclination angle. A horizontal wrap portion 15 is integrally bent from the upper end of the front end portion 14 toward the sunroof unit 4 side. The wrap portion 15 covers the corresponding end 16 of the sunroof unit 4 from above. The wrap length (overlap length) A of the wrap portion 15 with respect to the corresponding end portion 16 is set smaller than the clearance B between the corresponding end portion 16 and the front end portion 14 in the front-rear direction. The rear end (not shown) of the lower opening 13 has the same structure.

A method of forming the wrap portion 15 will be described with reference to FIGS. When the head lining 7 is entirely formed by heating, the tip 1
7 are formed so as to extend linearly from the front end 14 (see FIG. 3).

Then, the tip portion 17 is heated and softened by hot air H. Between the front end portion 17 and the front end portion 14, a shielding plate 18 for shielding the hot air H is installed. Only the end of the tip portion 17 softened by the hot air H is folded back by a jig (not shown) to form a double structure.
7 is bent by a jig to form a wrap portion 15 (see FIG. 4).

Next, how to attach the headlining 7 will be described. In this embodiment, there are two attachments.

The first mounting method is a method using the clearance B. That is, the front end (and the rear end) 14
When the head lining 7 is mounted from below the sunroof unit 4, first, the head lining 7 is separated from the rear clearance B by the clearance B between the wrap portion 15 and the corresponding end 16. Just slide back. Then, since the front end of the front wrap portion 15 is located behind the corresponding end portion 16, the wrap portion 15 can be placed on the corresponding end portion 16 as it is. When the head lining 7 is slid forward until the front end 14 hits the corresponding end 16 while the front lap 15 is placed on the corresponding end 16, the rear wrap (not shown) The part can rest on the rear corresponding end. Therefore, from this state, if the head lining 7 is slightly returned to the rear and the corresponding dual locks 5 and 12 are engaged with each other, a proper mounting state of the head lining 7 can be obtained.

The second mounting method is a method in which the wrap portion 15 is forcibly bent. That is, the head lining 7
When attaching from below, put your finger on the wrap part 15,
The front end (and the rear end) 14 are forcibly bent toward the inside of the lower opening 13. Although the head lining 7 of this embodiment has a double structure in which only the tip of the wrap portion 15 is folded, the other portions have a thin thickness of only one thermoplastic resin layer 8. Therefore, it is easy to bend. Therefore, as described above, the operation of bending the wrap portion 15 is easy to perform.

The head lining 7 attached by any of the above methods has the lap portion 15 covering the corresponding end portion 16 from above, so that the sun roof unit 4 and the head lining 7 can be connected to each other even if there is a component dimensional error. There is no gap between them, which would reduce the appearance. In addition, as described above, the head lining 7 is slid back and forth, or the wrap portion 15 is forcibly bent while the structure having the lap portion 15 is provided, so that the head lining 7 is attached to the sunroof unit 4 as before. On the other hand, since it can be mounted from below, it is advantageous in terms of mounting workability.

In the embodiment described above, the dual locks 5 and 12 are taken as examples of the "fastener member", but the present invention is not limited to this.

[0024]

According to the first aspect of the present invention, the wrap portions formed at the front end and the rear end of the lower opening of the head lining cover the corresponding end of the sunroof unit from above. Even if there is, there is no gap between the sunroof unit and the head lining that reduces the appearance. Further, when the head lining is mounted from below, the wrap portion can be positioned above the corresponding end of the sunroof unit by bending the wrap portion inward of the lower opening. Therefore, the head lining can be attached to the sunroof unit from below, as in the related art, even though the structure has the wrap portion, which is advantageous in terms of installation workability.

According to the second aspect of the present invention, only the wrap portion of the head lining has a double structure, and the thickness of the thermoplastic resin layer at the front end and the rear end of the lower opening is half that. The front end and the rear end are easily bent, so that the work of mounting the head lining is further facilitated.

According to the third aspect of the present invention, the clearance in the front-rear direction between the front end and the rear end of the lower opening of the head lining and each corresponding end of the sunroof unit is equal to the lap portion and the corresponding end. Since the lap length is set to be equal to or longer than the lap length, the head lining is slid back and forth using this clearance, whereby the lap portions can be sequentially placed above the corresponding ends. Therefore, even if the head lining is made of a material that is not easily bent, the workability of mounting the head lining does not decrease.
