Road tests with registration of the accelerations for a conventional child seat and a pendulum type tilting child seat are performed. Results for the spectral densities of the linear accelerations along the orthogonal axes are presented. The quadratic means of accelerations acting on both seats are calculated and compared. Results for the motion sickness dose value are obtained. A http .
