Impactors are used in Pedestrian safety test procedures developed by various international bodies including 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). In addition to these test procedures, the European Automobile Manufacturers’ Association (ACEA) produced a voluntary industry commitment for pedestrian friendly car fronts. Their proposals included tests with free-flight adult and child headforms for the evaluation of vehicle bonnet safety.
These tests were introduced 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, replaced the previous directives 2003/102/EC and 2005/66/EC. A Global Technical Regulation (GTR-9) which includes these tests has also been agreed.
- Free Motion Headform
- Ejection Mitigation Headform
- Knee Ligament for Pedestrian Legform
- Pedestrian Headform Impactor and Skin
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.
Cellbond is continuously developing and enlarging its product range for crash laboratories and passive safety research. To respond to 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.
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.
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.
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’s advanced Pedestrian Legform Impactor (aPLI) has been selected for future Euro NCAP and China NCAP testing protocols. The aPLI builds on the development of the original legform impactor, the Flex-PLI, by adding an upper mass and modifying the Flex-PLI specifications by means of sensitivity analysis on biofidelity, durability, versatility and ease of use.
