Inflatable inner tube for e.g. motor vehicle, has breaker units and side bumper units formed with airballs, which are mounted to insertion slots and curved groove respectively

摘要

Breaker units (30) has flexible base pads (302) formed of large number of airballs attached with breaker (301) to one side of base pads (202). Side bumper units (20) comprises flexible base pads formed of large number of air balls attached with breakers (201) to one side of the base pads. Breaker units and the side bumber units are mounted in insertion slots (102) and curved grooves (101) respectively. The curved grooves are spirally formed at two opposite side walls of an inflatable tube (10) with air chamber (103). The insertion slots are spirally arranged around the curved grooves.
