Abstract

PROBLEM TO BE SOLVED: To facilitate free movement of a user while eliminating low strength part from a reinforced part by dividing the front face of a vest vertically into two, providing an overlapped part between upper and lower members making the lower member slidable relative to the upper member in the overlapped part. SOLUTION: An upper member 3 for principally protecting the breast of human body is made by applying a nonwoven fabric of aramid fibers to the rear surface of a prepreg laminate of aramid fibers, for example. A lower member 4 for principally protecting the abdomen of human body is made by applying a nonwoven fabric of aramid fibers entirely to the rear surface of a prepreg laminate of aramid fibers, for example. It is divided into two in order to make smooth the movement of breast and abdomen. The upper and lower members 3, 4 thus divided are coupled slidably with a flexible coupling material so that movement of the lower member 4 can be set with a desired width. The coupling material is secured to the upper and lower members 3, 4 by means of adhesion or a metal rivet.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective vest excellent in wearability.

[0002]

2. Description of the Related Art Conventionally, a protective vest has been formed by forming a pocket at a front portion or a rear portion thereof and mounting a reinforcing member having excellent blade-proof property therein. This reinforcing member is usually formed of a single plate-like body, and has a drawback that free movement is restricted when worn. In some cases, the reinforcing member is divided, but it is necessary to connect them, and there is a disadvantage that the protection of the joint portion tends to be insufficient. For example, the overlap of the joints between the reinforcing members changes due to the action of the wearer, and a sufficient reinforcing effect is unlikely to appear. Conversely, in order to make the overlap of the joints constant, it is necessary to fix the reinforcing members to some extent,
The disadvantage is that the movement of the wearer is considerably restricted.

For example, when a plurality of reinforcing members are entirely bonded to a flexible reinforcing sheet on the back surface, the strength of each reinforcing member at the end is low. Further, as shown in FIG. 5, when the reinforcing members are overlapped, a vacant point is generated at the intersection as shown at point A, which is not preferable for a sharp-edged tool such as an ice pick. Therefore, careful consideration is required for superposition. Furthermore, because of the spread structure without space,
There is a drawback that flexibility is impaired in left and right or up and down movement. In addition, when small pieces of the reinforcing member are overlapped as shown in FIG. 5, the whole shape becomes planar, and in many cases, an uncomfortable feeling is generated at the time of mounting.

[0004]

When the reinforcing member is a single plate-like body or a structure in which a plurality of small pieces are combined like a conventional protective vest, it is difficult for the wearer to freely move. However, the present invention has been made as a result of various studies in order to solve the flexibility of expansion and contraction of the abdomen of the wearer, and facilitates the free movement of the wearer by dividing the reinforcing member into upper and lower two parts, An object of the present invention is to provide a protective vest in which a reinforcing member does not have a low strength portion for safety against a weapon.

[0005]

According to the present invention, the front surface of the vest is divided into upper and lower parts so as to facilitate the vertical movement of the vest when worn, and an overlapping portion is provided between the upper and lower members. A protective vest having a structure in which a lower member can slide up and down with respect to an upper member.

The protective vest of the present invention, particularly a typical example of a reinforcing member thereof, will be described with reference to the drawings.
FIG. 1 is a front view of a protective vest (one example) of the present invention. FIG. 2 is a front view of a reinforcing member (one example) used in the present invention. 3A and 3B are cross-sectional views taken along line AA of FIG. 2. FIG. 3A shows a state where the lower member is lowered, and FIG. 3B shows a state where the lower member is raised and is in contact with the upper member. 4A and 4B are horizontal sectional views of FIG. 2, wherein FIG. 4A is a sectional view taken along line BB, and FIG.
It is -C sectional drawing. The illustrated reinforcing member is made of a high-strength plastic and comprises an upper member (3) and a lower member (4), both members being connected by a flexible connecting member (9).

The upper member (3) mainly protects the chest of the human body. For example, the upper member (3) is formed by laminating an aramid fiber nonwoven fabric (6) on the back surface of an aramid fiber prepreg laminate (5). The aramid fiber prepreg laminate molded article is obtained by impregnating an aramid fiber with a phenol resin, an epoxy resin, a polyurethane resin, an unsaturated polyester resin, and the like, followed by molding and curing. The aramid fiber nonwoven fabric is stuck not on the entire back surface of the aramid prepreg laminated molded product (5) but on a certain width at a lower portion thereof. This width is slightly larger (usually larger by about 5 to 10 mm) than the length that the lower member slides. The lower member (4) mainly protects the abdomen of the human body. For example, the lower member (4) is formed by laminating an aramid fiber nonwoven fabric (8) on the entire back surface of the aramid fiber prepreg laminate (7). In these upper and lower members, the aramid fiber prepreg laminated molded product on the surface has a protective action against a weapon such as a knife, but in addition to such a material, a thermosetting or thermosetting woven fabric of high-strength fiber is used. Apply or impregnate a plastic resin,
Heat-press molded products can also be used. The aramid fiber nonwoven fabric on the back improves the feeling of wearing,
It also has a protective action against weapons.

A two-part structure of the reinforcing member, which is a main point of the present invention, will be described. In the present invention, the movement of the chest and abdomen is divided into two in order to make the movement smooth. Since the upper and lower members divided into two are slidably connected by the flexible connecting member (9), the movement of the lower member can be set to a desired width. The connection member (9) can be fixed to the upper and lower members by bonding or metal rivets. Further, by fitting the horizontal curved surface to the body curve as shown in FIG. 4, the feeling of wearing is improved. The length that can be slid up and down by the connecting member (9) is preferably 15 to 25 mm. Within this range, when the body is bent when worn, the body can be bent smoothly, and the good wearing feeling is not impaired.

The aramid fiber prepreg laminated molded article preferably used in the present invention has an area density of 200 to 50.
A molded product obtained by laminating 5 to 25 plies using an aramid fiber woven fabric of 0 g / m ² exhibits the most blade-resistant effect, and a molded product of 8 to 25 plies may also exhibit the anti-ballistic effect. The aramid fiber nonwoven fabric on the back side preferably has an areal density of 1.5 to 2.3 kg / m ² for effective impact absorption, and 1.7 to 2.2 kg / m ² .
1 kg / m ² is more preferred.

[0010]

Embodiments of the present invention will be described below. Area density 4
A prepreg was obtained by impregnating and drying a 00 g / m ² aramid fiber woven fabric with a resole-type phenol resin so that the resin content was 15% by weight. This prepreg 8 ply was heated and pressed to obtain a molded product having a thickness of 3 mm. This molded product was cut into upper and lower members having a shape as shown in FIG. An aramid fiber nonwoven fabric having a surface density of 2.0 kg / m ² (thickness: 6 mm) was bonded to the back surface with an adhesive. However, the upper member had a lower portion having a width of 30 mm and no nonwoven fabric. Next, the upper and lower members were connected by two connecting cloths made of polyester fiber having a width of 25 mm. The upper and lower members and the connecting cloth were bonded with an adhesive at both ends of the connecting cloth such that the upper member and the lower member overlapped by 10 mm. The reinforcing member obtained by dividing the upper and lower parts into two parts in this manner is such that the lower member is
Slide 0 mm.

A protective vest using this reinforcing member is:
As for the blade resistance, sharp blades such as a butterfly knife and an ice pick are highly effective. In addition, an effect is exhibited also in the elasticity resistance by attaching the nonwoven fabric to the back surface. In addition, since the reinforcing member is divided into upper and lower parts, the shape of the protective vest changes appropriately depending on the posture of the wearer, so that the wearer maintains a good wearing feeling when sitting and standing upright, and restricts the behavior. Nothing.

[0012]

According to the protective vest of the present invention, the reinforcing member is divided into upper and lower parts and processed so as to match the curve of the body in both the upper and lower parts. It is possible to remove a feeling of incongruity at the time of bending and stretching of the abdomen at the time of wearing, which is a conventional defect.
