Recently, the wagon for European has been developed. The characteristic of this vehicle is to have a capability of large luggage space.Therefore the passenger needs to be protected from injuries by sudden inflow of baggage from luggage room. This is also a requirement of EU regulation (ECE R-17). Barrier Net[1, 2, 3] to small size wagon has been adopted for the first time based on advanced foreign supplier's technology. This reality still gives us the burden of high cost and royalty expenditure.The objective of this study is to overcome these restrictions, especially for patent circumvention and secure the new design concept which is entirely independent of the present system in addition to cost effectiveness.
