Abstract: A seat belt of a vehicle including an air belt to stably and reliably protect an occupant during a vehicle crash. The seat belt includes a cover made of a fabric material, upper and lower webbings respectively fixed to opposite ends of the cover, a D-ring fixed to the upper webbing and arranged within an occupant compartment of the vehicle, a retractor fixed to the lower webbing to wind and unwind the lower webbing; and an air belt to rapidly supply a high-pressure gas into a bag held in the cover during a vehicle crash, and thus, to inflate the bag. Since the bag is covered by the fabric cover, an improvement in wearing comfort is achieved.

Abstract: A roller D-ring for a seat belt of a vehicle including a cylindrical roller, and a body having a folded structure to hold the roller by a folding portion of the body while allowing the roller to be rotatable. The folded structure is formed in a state in which the roller is seated on the folding portion of the body. The body defines, together with a peripheral surface of the roller, a gap, through which a webbing of the seat belt passes. Since the roller D-ring includes only two constituent elements, that is, the body and the roller, it is possible to reduce the manufacturing costs in accordance with a reduced number of constituent elements.

Abstract: A pipe fixing device comprising a plurality of pipes, for conducting liquid or gas, arranged to cross each other, and a fixing member for fixing the plurality of pipes. The fixing member comprises a plurality of pipe fixing bores, and a plurality of fitting bores for the fitting of bands used to tighten the pipes. The present invention can secure not only easy insertion of the pipes arranged to cross each other, but also enhancement in a coupling force of the pipes through the use of the tightening bands, resulting in stable and reliable fixation of the pipes.

Abstract: A pipe damping device including a damping member for reducing vibration of a pipe. The damping member includes a body, a pipe insertion bore formed in the body for the insertion of the pipe, and one or more specimen insertion bores formed in the body, into which one or more specimens, having different masses, are inserted, respectively.
