Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a vehicle cardboard headlining mounting structure provided on the inner surface of a roof panel of a cab-over truck or the like.

[Prior Art] Generally, a headlining is attached to an inner surface of a roof panel of a vehicle in order to improve quietness of the vehicle.
In a cab-over type truck or the like in which a nap bed is provided at the rear of the driver's seat, conventionally, front and rear decorative plates made of glass wool or the like that are divided and molded so as to follow the inner surfaces of the roof panels on the driver's seat and the nap bed, respectively, The curtain rails for partitioning the driver's seat and the nap bed are arranged along the overlapping portions of the front and rear decorative panels so that the edges are overlapped with each other on the inner surface of each roof panel, and the tapping screw is used. The curtain rail was fixed and the front and rear decorative plates were overlapped together.

However, as described above, using a molded product such as a decorative plate as the head lining has the drawbacks of high cost and heavy weight. For this reason, recently, low cost, light weight and heat resistance have been achieved. BACKGROUND ART A headboard is used in which a surface of a corrugated cardboard substrate having excellent properties and sound insulation is pasted with a skin through a foam material such as urethane.

Generally, as shown in FIG. 5, the cardboard substrate 1
Is formed by adhering sheets 3 and 4 on the upper and lower surfaces of a corrugated core paper 2 which is processed into a corrugated shape.
A head lining 7 is formed by sticking a skin 6 on the lower surface via a foam material 5 such as urethane.

As shown in FIGS. 3 and 4, the head lining 7 is attached by aligning the ridge line direction X (see FIG. 5) of the corrugated paper 2 of the cardboard base material 1 with the front-back direction of the roof panel 8. The head lining 7 is pressed against the roof panel 8 so that the upper surface of the seat 3 comes into contact with the lower surface of the bracket 9 fixed between the bead surfaces 8a of the roof panel 8 protruding inward of the vehicle, and is fixed by a clip or the like not shown, and the curtain The rail 10 is attached to the inner surface of the roof panel 8 by fastening the tapping screw 11 to the bracket 9, and also serves to fix the headlining 7.

[Problems to be Solved by the Invention] However, while the inner surface of the roof panel 8 is a curved surface that bends with a gentle curvature in the front, rear, left, and right, the headlining 7 has a flat plate shape, and the corrugated shape of the core paper 2 is continuous. That is, since the rigidity in the direction perpendicular to the ridgeline direction X of the wave is relatively low and the rigidity in the ridgeline direction X of the wave is high, the conformability of the headlining 7 to the left-right direction of the inner surface of the roof panel 8 is relatively good, but the roof panel 8. The head lining 7 was poorly fitted in the front-back direction of the inner surface 8, and wrinkles and bends extending in the left-right direction were generated in the skin 6 and the foam material 5, resulting in a poor appearance and poor mounting workability.

In view of such circumstances, the present invention is to provide a corrugated cardboard headlining mounting structure for a vehicle capable of preventing wrinkles and bending and improving workability.

[Means for Solving the Problems] The present invention provides a head lining having a corrugated cardboard base material having a corrugated core paper so that a ridge line direction of a wave of the core paper coincides with a front and rear direction of the roof panel. In the vehicle cardboard headlining mounting structure for mounting a curtain rail extending in the left and right direction of the roof panel on the inner surface of the roof panel while being mounted on the inner surface, in the carboard headlining mounting structure for a vehicle, the cardboard base material upper surface, A slit extending in the left and right direction of the roof panel is formed along the fixed position of the curtain rail.

[Operation] Therefore, when the head lining is pressed against the inner surface of the roof panel, the head lining slightly bends in the slit portion and fits well to the inner surface of the roof panel, and almost no wrinkles or bends are formed except the slit portion. Since the curtain rail is attached to the bending portion of the headlining, the appearance is not spoiled.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention, in which the same reference numerals as those in FIGS. 3, 4, and 5 represent the same parts.

As shown in FIGS. 1 and 2, a slit extending in the left-right direction of the roof panel 8 along the fixed position of the curtain rail 10 on the upper surface of the cardboard base material 1 forming the headlining 7.
Forming twelve.

Regarding the cutting depth of the slit 12, the roof panel 8
An appropriate value should be selected according to the curvature of the inner surface in the front-back direction.

In the figure, 13 is a mounting hole for fixing the headlining 7 to the inner surface of the roof panel 8 by a clip or the like, and 14 is a fixing hole for tapping screw penetration for fixing an end piece (not shown) of the curtain rail 10. Shows.

Next, the operation of the above embodiment will be described.

Since the slits 12 are formed on the upper surface of the cardboard base material 1 of the headlining 7, and the rigidity of the headlining 7 in the front-back direction (the ridgeline direction X of the corrugated paper 2) is lowered, the headlining 7 is attached. At this time, when the head lining 7 is pressed against the inner surface of the roof panel 8, the head lining 7 fits well to the inner surface of the roof panel 8 not only in the left-right direction but also in the front-back direction.

At this time, the headlining 7 is slightly bent in the portion where the slit 12 is formed, and wrinkles and bends are concentrated on the skin 6 and the foam material 5 along the slit 12, but this causes other Almost no wrinkles or bends are generated in the portion, and since the curtain rail 10 is attached to the portion where the wrinkles or bends are concentrated, there is no problem in appearance.

In this way, the conformability of the headlining 7 to the inner surface of the roof panel 8 is improved, wrinkles and bends can be prevented from occurring in the visible parts, and the appearance can be improved, and
It will be very useful for improving the mounting workability.

The vehicle cardboard headlining mounting structure of the present invention is not limited to the above-mentioned embodiment,
Needless to say, various changes can be made without departing from the scope of the present invention.

[Effects of the Invention] As described above, according to the vehicle cardboard headlining mounting structure of the present invention, the conformability of the headlining to the inner surface of the roof panel can be improved, and wrinkles and folds of the noticeable part can be improved. It is possible to achieve an excellent effect that the bending can be prevented and the appearance can be improved, and the mounting workability can be improved.
