Wraparound ventilation structure of air kutsushiyonshiyuzu

摘要

Topic With the wraparound ventilation structure of air kutsushiyonshiyuzu, containment the elasticity of the air back and the effect which alleviates the shock always, it makes also the effect of wraparound ventilation combine.SolutionsAir bag 11, air filling structure it is the air cushion itself of 12 and ventilating pipe 13, to flow to the air bag or the ventilating pipe it is possible the vapor inside air filling structure it prevents the time flow of the vapor via check valve 131, as for air filling structure Shank windpipe 121 is installed separately, it has reached the point where the vapor flows into to air filling structure with that, when stepping on air filling structure, neck 132 of the relatively small tube to be installed on the ventilating pipe, the vapor to flow into the air back first, the air bag gradually with the vapor expanding,When and, atmospheric pressure augments, for the first time, the vapor of air filling structure starts flowing to the ventilating pipe, several air which to the toe of switch of the ventilating pipe are puts out due to the hole 133 gushes to the effect of wraparound ventilation reaches.
