In a safety focused society the reduction of the effects of impact injury, to pedestrians and vehicle occupants alike, is becoming of ever increasing importance.
Various international bodies such as the European Enhanced Vehicle-safety Committee (EEVC) Working Group 10 (WG10) and Working Group 17 (WG17), the International Organisation for Standardization (ISO) and the Japanese Automobile Research Institute (JARI), worked on pedestrian safety test procedures. In addition, the European Automobile Manufacturers’ Association (ACEA) presented a voluntary industry commitment for pedestrian friendly car fronts. The proposals included tests with a free-flight adult and child headform for evaluation of vehicle bonnets.
We subsequently saw the introduction of these tests by the European New Car Assessment Program (EuroNCAP) and the adoption of a new European Commission regulation on pedestrian protection, numbers 78/2009 and 631/2009, which replace the previous directives 2003/102/EC and 2005/66/EC. A Global Technical Regulation (GTR-9) which includes these tests has also been agreed.

Cellbond have been working on the advanced Pedestrian Legform Impactor (aPLI) project since 2016, in collaboration with JAMA, JARI and ISO/TC22/WG5&WG6. While the Flex-PLI simulates the lower limb of pedestrians, a modified pedestrian legform impactor which could be used for testing with both low and high bumper vehicles was needed. The limitations of the Flex-PLI that needed to be addressed were: Limited kinematic biofidelity due to lack of upper body representation Lack of biofidelity in rebound phase response, angled bumper impact response and contact force against a car front end.
As part of Cellbond's development of a new Flex-PLI we undertook dynamic testing required for certification at Horiba MIRA. We are very pleased to announce that our impactor passed all dynamic testing ‘out of the box’, first time. This has been a result of our development team ensuring that all static test requirements were met as close to mid corridor as possible. As a result of this we are now able to offer our Flex-PLI verified to the official certification requirements.
The Free Motion Headform (FMVSS 201) is designed to help prevent injuries to occupants caused when their heads impact vehicle interior parts in a crash situation.
The EC Directives 2003/102 and 2009/631 require car manufacturers to provide pedestrian protection in passenger cars. In order to meet the requirements of the Directives, manufacturers must design cars with an appropriate crushable surface to cushion pedestrians, and to some extent cyclists, in the event of an impact.
In a safety focused society the reduction of the effects of impact injury to pedestrians and vehicle occupants alike, is becoming of ever increasing importance.
Cellbond is continuously developing and enlarging its product range for crash laboratories and passive safety research. To meet customers’ requirements for reasonable lead times and reliability of supply Cellbond has now developed and can manufacture both Free Motion Headforms and Ejection Mitigation Headforms.
