A supporting frame structure for a golf bag mainly mounted to a golf bag is made up of a compression spring, a linking rod, a linking rod top cover, a linking rod bottom base, a linkage pivot block, a pivot connector, a driving block, two coupling sleeves, two supporting legs and a fixing mount. Particular compositions and methods for producing a transparent clear coat layer include nanoparticles formed in-situ during curing of a transparent clear coat. The data stored in the storage, which can be personally identifiable information, can be stored in an encrypted form. When an energy absorbing member in a force limiter mechanism is deformed such that the webbing is pulled out, the piston is moved downward, the gas passing portion is opened by the slider so as to discharge the gas in the cylinder from the gas passing portion.
