Description

[Detailed Description of the Invention] The present invention relates to a ceiling structure for an automobile.

Conventional ceiling structures for automobiles have the structures shown in FIGS. 2-103 and 8 shown on page 9-63 of Automotive Engineering Handbook published February 25, 1970. To explain FIG. 8, on the inner surface of the roof panel 1, a bow-shaped ribbon is attached to a hanging bag 3 sewn to the head lining 2 at appropriate intervals, and the head lining 2 is hung with an appropriate tension. The bent end of the wire 4 is inserted into the mounting hole 6 of the roof side rail 5 and locked. When the wire 4 is locked to the roof side rail 5, it is bent so as to follow the inner surface of the roof panel 1, and is given a predetermined tension and rigidity to cope with the downward force of the head lining 2.

However, with such a structure, due to the recent trend toward flattening of roofs, it is not possible to provide sufficient bending allowance for the wire 4 (dimension a in the figure), and there is a limit to its tension rigidity, which raises the concern that the head lining 2 may sag. It was hot. In addition, since both ends of the wire 4 are attached at a relatively lower portion of the roof side rail 5, a sufficient temporal space within the vehicle interior cannot be secured. Furthermore, since the wire 4 has an arched shape and its end is bent, the suspension bag 3 needs to have an appropriate size in order to allow the wire 4 to pass through it smoothly. 2 has the disadvantage that it hangs down by the size of the hanging bag 3, which narrows the living space inside the vehicle.

The present invention was developed in view of the above-mentioned circumstances.The roof bow is fixed to the roof rail in the longitudinal direction of the vehicle body, and the resting wire, which is a linear material, is made into a substantially straight shape, and both ends thereof are locked to the roof side rail. To provide a ceiling structure for an automobile in which a substantially central portion is locked to a roof bow.

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

Note that parts that are the same as conventional parts are given the same reference numerals and their explanations will be omitted.

In the present invention, as shown in FIGS. 1 to 4, a roof bow 7 is provided that extends in the longitudinal direction of the vehicle body, and a retaining wire 4, which is a wire material, is formed into a substantially straight shape, and both ends thereof are attached to the roof side rails 5. The resting wires 4 (usually 4 wires) of the roof bow 7 are inserted and locked into the mounting holes 6 provided in the upper part.
A hook 8 is cut and raised at the intersection with the hanging bag 3, and a substantially central portion of the linear staying wire 4, which is exposed by a partial notch 9 of the hanging bag 3, is secured to the hook 8. In this case, the suspension bag 3 is formed to a size that allows the substantially linear resting wire 4 to be inserted therethrough.

5 to 7 show another embodiment of the present invention, in which a clip 10 is installed approximately at the center of the straight hanging wire 4 which is exposed by cutting out a portion 9 of the suspension bag 3. At the same time, a mounting hole 11 is bored in a portion of the roof bow 7 corresponding to the clip 10, and the clip 10 is locked in this mounting hole 11. Note that the mounting hole 11 is an elongated hole so that the setting position of the staying wire 4 can be changed.

As described above, according to the automotive ceiling structure of the present invention, since the resting wire is approximately straight,
The dimensions of the hanging bag can be shortened to approximately the same size as the resting wire, which not only makes it possible to reduce head lining droop and increase the living space, but also allows the hanging bag to be shortened to approximately the same size as the resting wire. Since it is fixed to the upper part of the roof side rail 5, a sufficient temporal space can be secured in the vehicle interior, and the bending process of both ends of the retaining wire can be omitted, so that costs can be reduced. In addition, since the approximately central portion of the straight resting wire is locked to the roof bow, the wire can be bent in a curved manner to cope with the downward force of the head lining without having to provide tension rigidity, which helps flatten the roof. It also has the advantage of being fully adaptable.
