Abstract

The paper presented in this poster details comparative frontal impact testing/data analysis to ECE R44 test requirements at child restraint system (CRS) seat base inclination angles ranging from 0-90 degrees to the horizontal. A CRS adapted to allow indexed rotation of the seat and occupant about the occupant's seated centre of mass was constructed to facilitate this. `ISOFIX' anchorages were used to eliminate the influence of the adult belt system and vehicle seat cushion. The tests employed a TNO P3 manikin which with its limited neck structure has recognised limitations. A brief summary of the manikin head/chest accelerations, manikin head travel (horizontal/veritical) and manikin head angular velocity is outlined. Analysis of the forward facing data indicates that seat base inclinations in excess of 50 degrees are undesirable from both chest `z' and chest resultant perspective.
