BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, S is a shell, M is a hammock, H is a headband, T is a chin strap, and a ceiling sheet 1 is detachably attached to the ceiling of the hammock M.

As is apparent from FIG. 2A, the ceiling sheet 1 has an insertion hole 2 through which the headband H is inserted.
And, a notch 3 communicating from the insertion hole 2 to the outside is formed. The insertion holes 2 have a number, a shape and a size corresponding to the number of the hammock M and the sectional shape and size. The cut 3 is preferably located at the center of the insertion hole 2, and may have a cut width b as illustrated.

FIG. 2 (B) shows an enlarged sectional structure of the ceiling sheet 1, which is composed of two layers of a nonwoven fabric 1a and a PP (special structure) woven fabric 1b. Nonwoven fabric 1
a is, for example, a polyolefin fiber such as polyethylene or polypropylene, a polyester fiber, a polyamide fiber, a composite fiber, a copolymer fiber or a single or two or more kinds of long fibers (filaments), short fibers (staples), or a laminate thereof Alternatively, it is composed of mixed fibers and can be obtained by a known spunbond method, needle punch method, thermal bond method, water needle method, or the like.

The thickness of the nonwoven fabric is 0.2 to 2 mm, more preferably 0.5 to 1.5 mm, and the basis weight is 100 to 300.
g / ^{m 2,} more preferably, it can be used 200 to 220 g / ^{m 2.} Breathability is 0.5-500cc /
cm ² · sec, more preferably 1 to 100 cc / c
m ² · sec. The average fiber diameter of the constituent fibers is 3 to
It is 10 denier, more preferably 5 to 8 denier.

The PP woven fabric 1b has, for example, a W Russell structure of polyester resin and has a 2.8 to 3.
It has a thickness of 0 mm.

FIG. 2C shows another structure of the ceiling sheet 1, which is composed of three layers of a nonwoven fabric 1a, a PP woven fabric 1b and a polyurethane foam 1c. Non-woven fabric 1
a is the same as that of the above two-layer structure. The above PP woven fabric 1
b is a mesh structure of polyester resin, and the polyurethane foam 1c has a thickness of 1.0 to 3.0 mm.

The ceiling sheet 1 of the above embodiment is used as a hammock M.
For attachment to, as shown in FIG. 3, the cut 3 is opened to the left and right, the hammock M is inserted into the opening 3 ', and the cut 3 is closed again. Therefore, especially the mounting portion of the ceiling sheet 1 (near the insertion hole 2 and the notch 3) has a certain degree of elastic strength.

FIG. 4 shows a bottom view and a plan view of the ceiling sheet of the helmet to which the ceiling sheet of another embodiment is attached. In this embodiment, the ceiling sheet 4 is attached to eight hammock M. ing. The insertion holes 4a for mounting are formed at four places, and are attached to the front hammock M and the rear hammock M of the eight hammockes M, respectively. 4b is a notch. A ventilation hole 4c is formed in the center of the ceiling sheet 4.

FIG. 5 shows a bottom view of a ceiling sheet of another embodiment attached to a hammock and a plan view of the ceiling sheet. In this embodiment, the ceiling sheet 5 is similar to the embodiment of FIG. Is attached to eight hammock M. Unlike the previous two examples, the hammock M attaching means of the ceiling sheet 5 of the present embodiment does not have the insertion hole 4a, and instead of this, a bilobal hooking piece 5a is formed. Figure 5
As shown in (A), the two leaf-shaped hook-and-hook pieces 5a are attached by hooking them from the space between two hammock M to the left and right. Therefore, this embodiment is effective when the two hammockes M are close to each other. 5b is a ventilation hole.

FIG. 6 shows a bottom view and a plan view of a ceiling sheet in which a ceiling sheet of another embodiment is attached to a hammock. In this embodiment, the ceiling sheet 6 is attached to six hammock M. Has been done. The insertion holes 6a for mounting are formed at four places, and are attached to the front hammock M and the rear hammock M of the six hammockes M, respectively. 6b is a notch and 6c is a ventilation hole.

FIG. 7 is a bottom view of another ceiling sheet attached to a hammock. In this embodiment, as shown in FIG. 8B, and is attached by being pierced through the cutout hole 7a of the ceiling sheet 7 as shown in FIG. 8B.

FIG. 9 is a bottom view in which another ceiling sheet is attached to the hammock. In this embodiment, as shown in FIGS. 10A and 10B, the hammock M has mounting holes. m'is provided, and the insertion piece 8a of the ceiling sheet 8 is inserted and attached as shown in FIG. 10 (C).

[0019]

[Effects of the Invention] 1) A user of a helmet can quickly and easily exchange a new one. 2) Since the main ceiling sheet can be attached at the final stage of the assembly process in the factory, not only is it easy to sew a hammock to attach the main sheet, but also the efficiency of the assembly process can be improved, and manufacturing is possible. Efficiency is improved and cost is reduced. 3) It has excellent sweat absorption. 4) It can be mounted securely.
