Description

  The present invention relates to a clothes-type airbag, which is used automatically on the land, for example, when the motorcycle falls over while driving a motorcycle, and is automatically filled with gas to protect the user's body. The present invention relates to a clothes-type airbag that is automatically filled with gas when the airbag falls into the airbag, and a so-called life jacket effect is obtained.

  Conventional clothes-type airbags have a connection hole formed on the inner surface of an airbag having the shape of a vest worn by a user, and a gas output hole of a gas discharge seat is screwed into the connection hole to form a gas discharge seat. One end is connected to an opening of a cylinder. In the case of using such a clothes-type airbag, when riding on a motorcycle, a ring connected to one end of a wire is fitted to an appropriate place of the motorcycle. When an accident occurs and the user's body is ejected from the motorcycle, the wire connected to the ring is pulled by the force of the human body being ejected. In this case, in the structure for connecting the other end of the wire, the upper end is provided so that the sphere abuts on the pressing pin having a conical shape, and the upper end of the pressing pin receives the pressing force of the sphere and the upper end of the cylinder opens. Liquid carbon dioxide filled in a compressed state in the cylinder is released instantaneously, and filled into the air bag from the gas output hole of the gas discharge seat, and the air bag is filled with gas. It becomes a filled waistcoat and protects the user from impact.
