Dr. A. Konosu presented informal document GTR9‐C‐04 that provides a short overview on the history of the FlexPLI: Accident statistics had shown a need for the protection of pedestrians specifically from suffering injuries to the head and the legs. Consequently, pedestrian protection requirements had been developed.

However, Japan could not accept the test tool representing the leg that was developed by the European Enhanced Vehicle‐safety Committee (EEVC) and that was used in their test procedures proposed for legislation and consumer testing. The main reason for this was the limited ability to also assess injuries to the bones. The Japan Automobile Research Institute (JARI) and the Japan Automobile Manufacturers’ Association (JAMA) therefore had started at around 2001 to develop the Flexible Pedestrian Legform Impactor (FlexPLI).

Since then, several built levels of the new tool had been presented and later the work was shared within a Technical Evaluation Group (TEG) under the supervision of GRSP. The result of these activities is the impactor that will be subject of discussion in this Informal Group, the FlexPLI version GTR (also referred to as Flex‐GTR).
