To improve passenger safety, seatbelt systems with pre-tensioner that tightens seatbelt webbing using explosive just before collision are widely used these days. Even though seatbelt must not unlatched without passenger's operation, explosive power of pre-tensioner can cause unlocking of a buckle. To prevent the unlocking, an Anti-g mass that blocks displacement of the release button has been attached to the buckle. In this study, the dynamics and statics of locking mechanism associated with operation of Anti-g buckle has been theoretically investigated, and important design variables that affect the operation of Anti-g buckle have been identified. Through the total seatbelt system's dynamic simulation using force and displacement inputs obtained from seatbelt sled test, design of the proposed Anti-g buckle has been validated.

Motorized retractors enhance the safety of passengers by removing the slack of webbing and by holding upright driving position. Reliability of a driving mechanism that includes one-way clutch between the driving motor and webbing is directly linked to the safety of passenger. In this research, conditions for locking one-way clutch and also conditions for sustaining locking are theoretically investigated. the operation of a motorized retractor under realistic conditions is simulated in order to validate the proposed retractor design.

A Graphic User Interface Program has been developed for real-time vehicle analysis software, which can be used for hardware-in-the-loop simulation application. A Graphic User Interface program integrates vehicle modeling pre-processor, analysis processor, and visualization post-processor. In vehicle modeling pre-processor, vehicle hard point data for a suspension model are automatically converted into multibody vehicle system data. An animator, which shows visualization using orientation and position data of each body, has been developed using open inventor graphic library. VPG(Virtual Proving Ground) environment has been also developed by using OpenGL for virtual vehicle handling test. In this visualization post-processor, vehicle virtual test simulation results are animated with virtual testing environments.
