Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile ceiling structure for temporarily placing the molded ceiling along the indoor surface of the roof panel when performing a lining work for fixing the molded ceiling to the indoor side of the roof panel. is there.

[0002]

2. Description of the Related Art When fixing a molded ceiling to a reinforcement of a roof panel with an external clip, the molded ceiling is temporarily placed along the indoor surface of the roof panel prior to clip fixing. For this reason, conventionally, as shown in FIG. 6, a longitudinal rib 3 that absorbs the impact of a side collision formed in a lattice shape that is located on the center pillar 9 while being arranged along a roof side rail (not shown). A U-shaped cutout hole 40 is provided in (hereinafter, simply referred to as EA rib) to form the molded ceiling 1.
The recessed portion 5 of the end edge 2 was mounted on the cutout hole 40 and hooked.

[0003]

The original function of the EA rib 3 which serves as a temporary stand for the molded ceiling 1 is to satisfy the shock absorbing performance. Since it cannot be removed, the molded ceiling 1 immediately after temporary placement
The stress due to the weight of is concentrated on the EA rib 3. As a result, as shown in FIG.
1 may be broken, and the molded ceiling 1 has a tendency to be deformed inward by springback during molding, and when temporarily set on the EA rib 3, the molded ceiling 1 is displaced in the left-right direction. Then, as shown in FIG. 8, the edge 2 may come off from the notch hole 40 and fall off.

An object of the present invention is to provide an automobile ceiling structure which can be temporarily placed on the EA rib without wrinkles or breaks in the molded ceiling or falling off.

[0005]

According to the present invention for achieving the above object, as described in claim 1, a molded ceiling arranged on the indoor side of the roof panel is provided along the roof side. In a device provided with a means for latching to a notch hole provided in a shock absorbing rib of a side collision and temporarily placing it, the notch hole is formed into a hook shape, and an edge of the edge of the molded ceiling that is hooked to the notch hole A box-shaped convex portion having a locking portion that engages with the hook-shaped portion of the cutout hole is formed in the surface, and the convex ceiling portion of the molded ceiling of the portion that engages with the hook-shaped portion of the cutout hole is formed by this convex portion. It is characterized by improving the rigidity of the edge portion.

According to a second aspect of the present invention, the molded ceiling, which is arranged on the indoor side of the roof panel, is tentatively fixed by being hooked on the notch hole provided in the impact absorbing rib of the side collision provided along the roof side. In a means provided with a placing means, a fragile portion that absorbs stress that causes wrinkles and folds from the edge portion of the molded ceiling is provided in the surface of the edge that is hooked to the cutout hole of the molded ceiling. It is characterized by that.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

[Embodiment 1] FIGS. 1 and 2 show Embodiment 1 of the present invention. In FIG. 1 and FIG. 2, 1 is a molded ceiling arranged on the indoor side of a roof panel (not shown), and 2 is an edge of the molded ceiling 1. As shown in FIG. 6, a vertical rib 3 (hereinafter referred to as EA) that absorbs the impact of a lattice-shaped side collision formed on the center pillar 9 while being arranged along a roof side rail (not shown). (Abbreviated as rib)).

The first embodiment of the present invention has the above-mentioned configuration,
A hook-shaped cutout hole 4 is provided in the EA rib 3, and the hook-shaped portion of the cutout hole 4 is formed in the surface of the end edge 2 in the recessed portion 5 of the end edge 2 of the molded ceiling 1 which is hooked to the cutout hole 4. A box-shaped convex portion 6 having a locking portion 7 that engages with is formed, and the convex portion 6 engages with the hook-shaped portion of the cutout hole 4 at the end edge portion 2 of the molded ceiling 1. It has improved rigidity.

Since the first embodiment of the present invention has the structure as described above, the end edge 2 of the molded ceiling 1 is formed from the recess 5 to the EA rib 3.
By being inserted into and mounted on the cutout hole 4, the engaging portion 7 formed on the convex portion 6 engages with the hook-shaped portion of the cutout hole 4 and is hooked. As a result, the molded ceiling 1 is positioned and temporarily placed along the indoor surface of the roof panel. Moreover, since the locking portion 7 formed on the convex portion 6 is engaged with and hooked to the hook-shaped portion of the cutout hole 4, there is a tendency to deform inward due to springback during molding. The ceiling 1 is prevented from falling off from the cutout hole 4.

Further, the convex portion 6 improves the rigidity of the end edge portion 2 of the molded ceiling 1 at the portion engaging with the hook-shaped portion of the cutout hole 4, and wrinkles or folds from the end edge 2 of the molded ceiling 1. Etc. are prevented from occurring. Even if wrinkles or folds occur, as shown in FIG. 3, the wrinkles or folds 8 are made to proceed at a substantially central portion in the longitudinal direction of the protrusion 6 so as to be orthogonal to the longitudinal direction of the protrusion 6. Prevent it from spilling inward and make it invisible from the room.

Further, the box-shaped convex portion 6 formed on the end edge 2 has increased strength, the rigidity for supporting the temporary placement of the molded ceiling 1 is secured, and the temporary placement portion of the molded ceiling 1 by the EA rib 3 is heavy. The molded ceiling 1 can be easily fixed to the reinforcement of the roof panel with a clip without being deformed by the clip.

[0012]

Second Embodiment FIGS. 4 and 5 show a second embodiment of the present invention. In FIG. 4 and FIG. 5, 1 is a molded ceiling arranged on the indoor side of a roof panel (not shown), and 2 is an edge of the molded ceiling 1. As shown in FIG. 6, the reference numeral 3 indicates a center pillar 9 which is arranged along a roof side rail (not shown).
It is a rib 3 in the vertical direction (hereinafter abbreviated as EA rib) which absorbs the impact of a side collision formed in a lattice shape.

The second embodiment of the present invention has the above-mentioned structure.
Wrinkles, folds, etc. from the edge 2 of the molded ceiling 1 are formed in the surface of the edge 2 of the recessed portion 5 of the edge 2 of the molded ceiling 1 that is hooked into the cutout hole 4a provided in the EA rib 3. This is a structure in which a fragile portion 10 that absorbs the generated stress is provided. It is desirable that the fragile portion 10 is formed of a bead and has a shape along the edge of the recessed portion 5, but it is not necessarily required to have a shape along the edge of the recessed portion 5, and the fragile portion 10 can be attached to the cutout hole 4a. It may be around the part to be stopped.

In the second embodiment of the present invention, the fragile portion 10 that absorbs the stress that causes wrinkles and folds from the edge 2 of the molded ceiling 1 is provided at the edge 2, so that the molded ceiling 1 is molded immediately after being placed. The stress caused by the weight of the ceiling 1 is concentrated on the EA ribs 3 and the stress that causes wrinkles and breaks from the edge 2 is absorbed by the fragile portion 10, and the wrinkles and breaks from the edge 2 are prevented from occurring. To do.

In the second embodiment as well, the EA rib 3 is used.
The cutout hole 4a is formed into a hook shape, and the engaging portion 7 that engages with the hook-shaped portion of the cutout hole 4a is provided at the end of the edge 2 of the molding ceiling 1 that is inserted into and mounted on the cutout hole 4a. Ceiling 1
Notch hole 4 for temporary positioning and spring back
It is desirable to prevent it from falling off.

[0016]

As described above, according to the present invention, when the molded ceiling is temporarily placed on the EA ribs, the stress due to the weight of the molded ceiling concentrates on the EA ribs, and from the edge of the molded ceiling toward the room. There is an advantage that wrinkles and breaks may be eliminated, and temporary positioning of the molded ceiling can be easily obtained, and the spring back of the molded ceiling can prevent the EA rib from falling out of the notched hole. There is.
