下がりを抑える必要がある。According to the reinforcing structure, a thick portion that is bent and overlapped is formed at an end,
Although a reinforcing effect is obtained by this, when the interior material is relatively large such as a ceiling material, the rigidity of the end portion becomes insufficient. Therefore, when used as a ceiling material, it is necessary to take measures such as partially increasing the weight per unit area of the base material, the so-called base weight of the base material, or adding a reinforcing material such as an iron plate to the end. . In addition, when the ceiling material has an opening for the sunroof, the hanging of the opening cannot be prevented only by providing the reinforcing structure according to the proposal on the periphery of the opening. Therefore, it is necessary to separately attach a hook-and-loop fastener or the like, thereby suppressing drooping.

As a result, it is expected that the rigidity of the end or side of the interior material is increased by about 3 to 4 times as compared with the case where no measure is taken on the end or side without increasing the basis weight. Therefore, on the one hand, the basis weight can be reduced and, on the other hand, the rigidity can be increased.

性が得られる。Since the ceiling material is made as a single piece, it is necessary that the overall rigidity be high in order to improve the workability when assembling the vehicle body and the retention of the shape after assembling. The department can handle this. When there is a hole for an air conditioner duct or a room lamp near the side of the ceiling material, the rigidity of the side is increased by the reinforcing portion. The maximum rigidity of the ceiling material can be obtained by providing a total of four reinforcements at two ends in the front-rear direction of the vehicle body and two sides in the width direction of the vehicle body.

に使用しており、廃棄量を減らすことができる。The ratio of the sunroof opening to the ceiling material is about 1/3. Therefore, the periphery of the opening is likely to sag, and as described above, sagging is prevented by using a hook-and-loop fastener. However, according to this aspect of the present invention, the sagging is prevented by the reinforcing portion provided on the periphery of the opening. Can be prevented. Also, in the past, the portion of the ceiling material resulting from opening the opening was discarded, but in the present invention, it is effectively used as a bent portion for forming a reinforcing portion or as a surplus portion, and is discarded. The amount can be reduced.

れぞれに設ける補強部は、設計上好ましい断面形状にす
べく定めた折り曲げ部によって形成する。The sunroof opening has a dimension in the width direction of the vehicle body larger than that in the front-rear direction of the vehicle body. This means that the sagging of the opening tends to occur along two of the four peripheral edges of the opening located in the front-rear direction of the vehicle body. Therefore, the reinforcing portions provided on each of the two peripheral edges located in the front-rear direction of the vehicle body are formed by bent portions determined to have a cross-sectional shape that is preferable in design.

車体の前後方向にある開口の周縁に沿って起こるため、
支障はない。The area of the two bent portions for the reinforcing portions of the two peripheral edges in the front-rear direction of the vehicle body is within the area of the opening.
Assuming that the reinforcing portions provided on each of the two peripheral edges in the width direction of the vehicle body are formed to have the same cross-sectional shape as the front and rear reinforcing portions, if the area of the four bent portions becomes larger than the area of the opening, The reinforcing portions provided on each of the two peripheral edges in the width direction are formed by bending the remaining portions obtained by subtracting the area required for the two front and rear bent portions from the remaining portions. Therefore, the rigidity of the reinforcing portion in the width direction of the vehicle body is smaller than the rigidity of the reinforcing portion in the longitudinal direction of the vehicle body. However, as described above, the drooping of the opening extends along the periphery of the opening in the longitudinal direction of the vehicle body. To happen
No problem.

部の垂れ下がり対策として問題はない。Conversely, even if the four reinforcing portions are formed in the same cross-sectional shape, if the area of the four bent portions is smaller than the area of the opening, the reinforcing members provided at the two peripheral edges in the width direction of the vehicle body are provided. The portion is formed in the same cross-sectional shape as the reinforcing portion provided on each of the two peripheral edges in the front-rear direction. In addition, the portion having a larger area than the bent portion of the reinforcing portion provided on each of the two peripheral edges in the front-rear direction is made extra. It can be used and bent. The latter has excessive rigidity, so to speak, but has no problem as a countermeasure against sagging of the opening.
