22. The expert from CLEPA introduced presentation GRSP-70-22 to explain the effect of chin-to-chest contact of dummies during type approval testing and potential solutions. GRSP endorsed in principle, as a pragmatic solution, the proposal from the expert from CLEPA that introduced the neck tension force limits based on measured type-approval monitoring data as proposed in GRSP-68-05. GRSP requested to continue sharing information at its May 2022 session on this subject awaiting an official proposal from the expert from CLEPA based on GRSP-68-05.
