Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a molded ceiling for a vehicle, and particularly to a molded ceiling for a vehicle body that is temporarily fixed to the roof rail of a vehicle body panel with a clip.

<<Prior Art>> The molded ceiling of an automobile or the like is positioned on the roof rail of a car body panel and fixed together with separate parts such as an assist grip, a room lamp, a sun visor, and an inside mirror, using screws, for example.

By the way, when attaching a molded ceiling to a roof rail, the single-piece molded ceiling must be held down and positioned with one hand, while at the same time tightening screws with the other hand, which makes work extremely difficult. It's summery.

Therefore, in order to improve the efficiency of the installation work, the molded ceiling is usually formed so that it can be temporarily attached to the vehicle body with a clip, etc., so that its position can be adjusted, before it is permanently attached to the vehicle body with a separate assist grip, room lamp, etc. In some cases, the molded ceiling is temporarily fixed to the roof rail using clips, and then the molded ceiling is adjusted and fixed using both hands. in this case,
In order not to spoil the appearance of the molded ceiling, the holding part for temporary fixing is an extension of the curved end of the molded ceiling that is hidden by a separate trim or garnish, and the extension is attached to the clip seating surface. It is used as.

[Problems to be solved by the invention] However, when the curved end portion is press-formed including the clip seat surface, the amount of deep tightening increases by the amount of the clip seat surface, so the press-formed product may have wrinkles, unevenness, cracks, etc. The problem is that constrictions and the like are more likely to occur, resulting in frequent appearance defects.

The present invention was devised in view of the above problems, and an object of the present invention is to provide a clip seating surface for temporary fixing on a curved end portion without adversely affecting formability in press molding.

<Means for Solving the Problems> In other words, the present invention temporarily fixes the molded ceiling to the roof rail in an adjustable position by clipping the curved end portion of the molded ceiling to the roof rail. The molded ceiling for a vehicle is such that a clamp portion during press molding is integrally extended to the curved end portion via a thin recess, and the clamp portion is bent at the thin recess to provide a temporary fixing clip. It is characterized by being used as a seat.

<<Operation>> The molded ceiling is temporarily fixed to the roof rail using the clamp part during press molding. In this case, the clamp portion can be easily brought into close contact with the roof rail surface via the thin recess.

<<Example>> Hereinafter, an example of the present invention will be described in detail using the drawings.

FIG. 1 is an overall perspective view showing a molded ceiling to which the present invention is applied.

In the figure, a molded ceiling 10 consists of a cardboard base material 11 press-molded to the inner surface shape of the ceiling, and a base material 1
A skin material 12 is attached to the inner surface of the lamp 1 with an adhesive such as hot melt, and a mounting hole 10a for a room lamp is provided in the center, and mounting holes 10b and 10c for assist grips, sun visors, inside mirrors, etc. are provided in the periphery. , 10d are provided as appropriate so that the molded ceiling 10 can be fixed together with a room lamp, an assist grip, a sun visor, an inside mirror, etc. with screws or the like.

Both side peripheral edges of the cardboard base material 11 are bent into a curve, and a clamp portion 13 for press molding is integrally extended to the curved end portion 11a via a thin recess 13a.

The clamp part 13 is appropriately trimmed leaving a plurality of clip seating surfaces 14 having through holes 14a (note that only one side of the base material 11 is shown in the figure, but the other side is similarly trimmed). clamp part 13
is formed).

FIG. 2 is a schematic diagram showing a press working method for the molded ceiling 10. After the base material 11 is cut according to the length of the ceiling, the cut blank is set in a lower die 20 and the upper die 21 is pressed with a desired pressure, thereby press-molding it into the inner surface shape of the ceiling. In this case, the base material 11 is cut to a size that allows for a clamping allowance of about 30 mm during press molding, and the clamp portion 13 is held down by the pad 22 during molding.
It is now possible to clamp it. Further, the lower die 20 is provided with a convex portion 20a for pressing on the peripheral edge thereof, and the clamp portion 13 is formed by press molding.
A thin recess 13a is formed at the base of the holder.

Therefore, as shown in FIG.
3 are integrally joined as they are through the thin recess 13a, and are formed to be bendable at the thin recess 13a.

Next, a skin material 12 formed separately from the base material 11
After bonding it to the inner surface of the base material 13 by press molding again, the molded ceiling 10 is completed by trimming the clamp portion 13 and the like as shown in FIG.

The molded ceiling 10 formed as described above has a fourth
As shown in the figure, it is temporarily fixed to the roof rail 24 of the vehicle body panel 23. That is, after the molded ceiling 10 is lifted and brought close to the roof rail 24, the clip seating surface 14 is bent through the thin recess 13a to bring it into close contact with the roof rail 2. Through holes 2 for temporary fixing provided in the roof rail 24
4a and the through hole 14a of the clip seating surface 14 in sequence, and are fixed with a resin clip 25.

This clip 25 is concealed by a roof circumferential trim or garnish 26 provided at the end of the molded ceiling 10.

By temporarily fixing the molded ceiling 10 in this way, the molded ceiling 10 can be effectively used to adjust the position and to efficiently fasten the molded ceiling 10 together with a separate assist grip, a room lamp, etc.

<<Effects of the invention>> As explained above, according to the invention, since the clamp part itself during press forming is used as a clip seating surface for temporary fixing, the amount of deep drawing at the curved end of the molded ceiling can be set to the minimum. can. Therefore, the occurrence of appearance defects such as wrinkles, unevenness, cracks, and constrictions in the press-formed product due to deep drawing can be drastically reduced, and the amount of molded ceiling base material can be saved. Further, since the clamp portion is brought into close contact with the roof rail through the thin recessed portion, it is possible to easily absorb changes in the shape of the roof rail.
