Abstract

<P>PROBLEM TO BE SOLVED: To provide a life jacket with a good air ventilating property. <P>SOLUTION: This life jacket is formed by a back body 1, a right front body 2 and a left front body 3. Each outer material a and a backing material b are sewed and connected into a bag shape in which each frame 4, 5 and 6 and a buoyancy material 10 using each synthetic resin foamed body such as a closed cell body made of urethane, etc. are stored. The frame 4 in the back body 1 is formed by a circumference part 4a, a center part 4b and four supporting beams 4c, 4d, 4e and 4f for connecting four corner insides of the circumference part 4a and the center part 4b. The center part 4b is projected to the outside in relation to a surface of the circumference part 4a, the supporting beams 4c, 4d, 4e and 4f are curved and formed, and a space A is formed between the backing material b and the buoyancy material 10. The buoyancy material 10 is applied and mounted at the outside of the frame 4 so that the buoyancy material 10 may be added. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、通気性のよいライフジャケットに関する。   The present invention relates to a life jacket having good air permeability.

従来ライフジャケットは特許文献１のように表地と裏地の間に浮力材が収納されているので、身体の形状に合わず、通気性も悪い欠点がある。
通気性を改善するために浮力材に孔を開けたり、浮力材を分割することが行われているが、孔を開けると成形工程でコスト高になり、分割しても表地と裏地の中で浮力材がくっついてしまうので通気性の効果が得られない。
特開平１１−２９１９８２号公報 Since the conventional life jacket has a buoyant material housed between the outer material and the lining material as in Patent Document 1, it does not match the shape of the body and has the disadvantage of poor air permeability.
In order to improve the air permeability, holes are made in the buoyancy material or the buoyancy material is divided. However, if the holes are made, the cost increases in the molding process. Since the buoyancy material sticks, the effect of breathability cannot be obtained.
JP-A-11-291982

解決しようとする問題点は、ライフジャケットの浮力材周辺の通気性が悪いことである。   The problem to be solved is that the air permeability around the buoyancy material of the life jacket is poor.
