Innovated Testing Equipment and the Influence of Two-Axis Loading on Comfort of Car Seats

Abstract

The car seat comfort depends on many parameters of the seat and the characteristics of the people sitting on the seat. Each person is different, behaves differently and feels differently. The seat cannot suit everyone, or it must be required the car seat to adapt automatically to the person sitting on it. That is why we test the car seat in real conditions in the car, i.e. in conditions of simultaneous loading of more axes. This paper describes the innovation of measuring equipment for car seats in laboratory conditions. The introduced innovated device allows realizing how vertical movement of the car seat as well as horizontal movement. The vertical movement can be realized independently or simultaneously with the horizontal movement. Measurement methodologies and test signals are also described in the paper.
