The sinking seat is the mounted seat in rear columns of recreational vehicle. The convenience of sinking seat is lower than folding seat because the paths of the containment and withdrawal are different each other. In this paper, the cam shape design model which is related recliner apparatus was introduced of the folding path of the existing manual system sinking seat. And the validity of the design variable was verified through the dynamic mechanics simulation using RecurDyn. but, the transformation-time graph of cam link joint position in RecurDyn is unstable because it is not consideration of friction.
