Presentation on work to characterize the difference of response between the APTS50 (50mm) in Q3 drilled child dummy and new APTS40 (40mm) in Q3 molded child dummy abdomen.

Working draft version with Class A and B (for phase 3 of UN R129 development) CRS locking devices.

Presentation to highlight inconsistencies in the lateral and forward cumulative head and chest acceleration injury criteria (determination of the maximum acceleration with a cumulative duration of at least 3ms).

Copy of GRSP/2015/32 for discussion during the 54th CRS informal group session. This proposal would limit the use of booster cushions (booster seats without backrest) to children taller than 125 cm and limit their type approval under UN R44 to Group III.

Copy of document GRSP/2015/24 for discussion during the 54th CRS informal group session. This proposal would extend the scope of UN Regulation No. 129 to include non-Integral child restraint systems (“Universal Booster” or “Specific to vehicle Booster”).

Informal group discussion version of document GRSP/2015/24, including proposed transitional provisions starting from 2018.

Review of UN R129 testing with regard to child dummy performance, submarining, pelvic/abdominal measurements, and injury criteria.

Summary of investigations into belt slippage (clavicle and neck) and chest deflection to define areas for improvement of the test procedures under UN R129.

Data to support change from plastic to aluminum hip cup in order to resolve Q-dummy problem where the plastic cup has not been strong enough to retain the hip joint (ball and socket) in position.

Presentation of proposal for interim solution to allow for booster cushions without a backrest to be kept in UN R44 (but prohibited for children smaller than 125 cm) pending development of provisions for non-integral i-Size booster seats with integrated backrest under UN R129 (Phase2).

Reference document for 54th CRS informal group discussion providing background on child stature discussions under the EU EPOCh (Enabling Protection for Older Children) project.

Working draft for document GRSP/2015/24/Rev.1 (Proposal for the 01 series of amendments to Phase 1 of Regulation No. 129) for submission to the GRSP.

Proposal to clarify the markings on modular CRS in order to minimize the potential for misuse of components. Since the base and the shell of an enhanced CRS can be sold separately, there is the possibility for mixing of elements from different CRS that have not been tested and approved as part of a modular system.

Presentation and proposal for clarification of language to avoid marking of stand-alone CRS that can be used as part of a modular CRS with markings under UN Regulation No. 44 and to ensure that all elements of a modular system are clearly tested, approved, and marked as parts of that modular system under UN R129.
