Among the various parts of automobile, automotive seat is the most fundamental item that ride comfort can be evaluated as the part contacted at human body. Dynamic stabilities on 3 kinds of models are analysed according to inside beam configuration of rear seat frame in this study. Model 1 has the basic design of straight beam. Model 2 has the beam that is curved slightly from model 1 configuration and model 3 has honeycomb structure. Total deformations and equivalent stresses are investigated when these models are crushed at side. Total deformations due to frequencies are also obtained and critical frequencies on these frequency responses are investigated. By comparing total deformation configurations of model 1,2 and 3, model 1 and 2 apply the damage to passengers but model 3 absorbs the damage. Model 1, 2 and 3 show total deformations of 482.7, 178.9 and 151.62 mm at the critical frequencies of 180, 200 and 150Hz respectively. Because model 3 does not apply the damage to passengers and the total deformation at critical frequency becomes minimum among three models on frequency response, this model becomes most stable among 3 kinds of models when crushed at side.
