Abstract
New functional seats are continually developed to use the recreational vehicle, and sinking seat is a functional seat that is necessary for sinking space. Stowage of the sinking seat is adjustable by manual operation. But seat is very difficult to manual operate because of the operational resistance to the seat weight. Recently, several vehicle companies are developing the handy automatic sinking seat in order to remedy manual operation's shortcomings. Automatic sinking seat is necessary development of optimization for operation sequence and modularization design of the electric driving system. In this paper, present the structural design method to the transition from manual to automatic operation of sinking seat and verified the validity by computer simulation.
