Foldable Car Seat

In this example we first guarantee the correct movements of the two parts of the seat through two syntheses for two separate mechanisms. An exact-pose synthesis is used to generate both of these partial systems, a one-bar and a four-bar linkage. After the motion design, we combine the two partial systems kinematically by adding a interlink. Subsequently, we examine the necessary manual forces for opening and closing with and without the presence of a supporting rotary spring. In a supplementary kinetostatic force analysis we examine the necessary motor torques with and without geared transmission. Lastly, a collision check for the two moving components of seat and backrest is added.
