Seat is one of the most important part of an automobile for passenger's safety especially when an accident happens. A recliner is a part of the seat assembly, having the function of adjusting the back-plate angle of a seat. Recently, many kinds of vehicles have adopted the round recliner module rather than the conventional types of recliners because of its broad compatibility and structural simplicity. In this study a two-dimensional finite element strength analysis has been performed using a commercial code ABAQUS/Standard for the purpose of developing a new round recliner model. The loading condition for the analysis is the same as the FMVSS 301 regulation. The finite element result for the round recliner has been compared with that for the conventional type.

This study presents the development of a round recliner using the finite element method. That reduces the number of test repeating times and gives an information about stiffness. A simulation model of round recliner mounting seat module and tooth strength simulation are established using a PAM-CRASH and ABAQUS. With the optimization of gear profile, structural strength design of round recliner was achieved. The round recliner seat module simulation, structure strength simulation and a crash safety are requested by FMVSS test. Solution of round recliner optimum variable study and design problem are searched for round recliner stress, deformation and application. Also an examination of safety is made.

The development of more safe recliners is an important issue in the automotive industry. However, the development of new recliners is costly and take much time because it is typically based on experimental evaluation using prototypes. This study presents the evaluation of rear crashworthiness for round recliner using finite element method. That reduces the number of repeating test and gives an information about stiffness. To evaluate rear crashworthiness, the FMVSS 301 simulation and pendulum impact simulation were performed. The load path on two simulations was observed and compared each other in this paper. Also stress, strain and internal energy was compared. It is attempted the tooth strength simulation using a substructure option on PAM-CRASH.
