Regulation of Child Restraint System and Use of APTS

12/dec/17 - The APT Sensors are now adopted in UN Regulation (*) for dummies used to certify child restraint systems. 

APTS in Q-Dummy abdomen

This process took time before it becomes compulsory and included into the regulation. This regulation has been entered thanks to the extensive work made by the EEVC - European Enhanced Vehicle Safety Committee (**).

Euro NCAP has not already introduced any APT sensors in dummy instrumentation for the child occupant protection tests. Nevertheless, companies who have anticipated the use of the APTS sensors to qualify their products are preparing the future and will have a noticeable benefit in their business.

International projects are also underway to extend the use of this sensor in adult mannequins like the 50th percentile male and the 5th percentile female.

(*) Agreement Concerning the Adoption of Uniform Technical Prescriptions. Regulation 129: Uniform provisions concerning the approval of Enhanced Child Restraint Systems used on board of motor vehicles. For frontal impact. The abdomen of the Q1.5, Q3, Q6 and Q10 are instrumented using Abdominal Pressure Twin Sensors (APTS).

(**) See Working Group 12 Report: “The use of thoracic deflection criteria balanced with abdomen pressure criteria for the Q-Series in frontal impacts”
