The objective of the study is to develop belt integrated seat mounted with round recliner and seat track. The performance of a belt integrated seat is evaluated using an occupant analysis software. Reaction force of a belt integrated seat is calculated by seat belt anchorage test(FMVSS 210) and rear crash test(FMVSS 301) analysis. Calculated reaction force is defined for target to valuate condition of round recliner and seat track. Mesh size and friction coefficient is determined through out simple tooth test. Seat mechanism, evaluated by tooth and track simulation, is applied belt integrated seat and conducted strength test. The study establishes the evaluation process of round recliner. Base on meet the strength target of tooth and seat track, it is possible to simulate seat system analysis and shorten CPU time. The current analysis model can provide useful informations to design a new car seat mechanism and can reduce the overall design cost and time.

The Seat Back latch system is used in the vehicle rear seat back. This latch system must be guaranteed the high strength to prevent seat back folding on the rear impact situations. And this latch system must be satisfied with both the reinforced safety regulations and the profitability of components supplier. So the latch core parts should be optimized within limited design form. To develop this latch core parts, it is necessary to estimate of the characteristics of the proper materials, heat-treatment and the design process from the FEM. In this study, The strength of variable core design were measured by FEM, the optimized design was verified by real test. The result of this study present the seat back latch core part design and it could be used production.

The objective of the study is to develop automotive seat module mounted with new recliner type, round recliner. Seat belt anchorage test(FMVSS 210), back moment test(FMVSS 207) and rear crash test(FMVSS 301 Upgrade) are analyzed to get the structural stability, and static strength is evaluated to design the tooth shape in detail. New type round recliner is designed and successfully applied to the automotive seat module by investigating various materials and several tooth shapes

This study presents the evaluation of rear crashworthiness for round recliner using finite element method. That reduces the number of test repeating times and gives an information about stiffness. To evaluate rear crash worthiness, the FMVSS 301 simulation and pendulum impact simulation are achieved. The load path on two simulations is observed and compared each other. Also stress, strain and internal energy is compared. From that, The correlation between two simulations is complained. And, It is attemped the tooth strength simulation used substructure option on PAM-CRASH. The simulation model of round recliner mounting seat module and tooth strength simulation are established using a PAM-CRASH.
