RUBBER DAM FOR AIR PRESSURE TYPE MOVABLE AND RUBBER DAM MANUFACTURING METHOD

摘要

The present invention relates to an airbag having an air gap and a method of manufacturing the same, the purpose of which is to allow a plurality of air gaps to be formed in the center of the air bag into which air is injected, thereby injecting air into the air bag and discharging air into the air bag. It is to provide an airbag for a movable beam and a method of manufacturing the same, having an air gap capable of smoothly improving the standing and conductivity of the movable panel. The airbag for movable walking according to the present invention includes an expansion part which is expanded and contracted by supply/exhaust of air through an air inlet, wherein the expansion part is provided so that an air gap having a predetermined depth is communicated with the air inlet. It is formed so that supply and discharge of air can be made quickly.
