In 2009, a program was started to look into developing a dummy to represent older children for use in crash test environments to determine safety of Crash Restraint Systems (CRS). The project was called ‘Enabling Protection for Older Children (EPOCh) and it focussed on the development and assessment of the Q10 dummy, as well as subsequent refinement and evaluation based on third party testing.
EU FP7 projects, Child Advanced Safety Project for European Roads (CASPER) and EPOCh, addressed the safety of children transported in passenger cars. While CASPER concentrated on improvements to the existing range of Q-series dummies, EPOCh realised a Q family member representing adolescents. The conclusion from extensive discussions was that a dummy representing a 50th percentile child of 10.5 years old was most appropriate to represent the group of the oldest CRS users.
Cellbond’s Q10 Development Process
The development process for the series was a funded European Project and as a result there is no individual or corporate ‘ownership’ of the designs; all information utilised to develop and in some areas improve the Q10 Dummy is in the public domain. Cellbond has used this information and drawn on our experience and knowledge to produce a Q10 which consistently meets all performance requirements throughout a comprehensive testing regime. All our development was funded by Cellbond without public funds.
Cellbond’s Q10 Upgrade Kit
on 24 October 2018 Euro NCAP approved Cellbond’s updates to the Q10 dummy for implementation in 2020:
- Limited upgrade kit for shoulders, spine box and sacrum according to Cellbond specification
- Femur flesh specification according to Cellbond specification
- Shorter feet on the Q10 according to Cellbond specification
The upgrades relate to shoulder and hip belt stability as well as to better positioning of the dummy.
The kit, which is available to order now from Cellbond, consists of the following parts:
- New shoulder liner that covers the shoulder joints
- Spine box with modified neck base positioning and increased mass
- Scapula’s for front and side impact testing
- Pelvis replacement parts compensating for the change in mass of the spine box
- Upper legs with solid moulded flesh
- Lower legs with shorter feet
The new shoulder liner is meant to avoid the belt getting trapped in the shoulder joint when sliding outboard. The effectiveness was shown in various tests reported to the Euro NCAP Child Safety Working Group. The Upper Leg specifications as applied in the Cellbond Q10 dummy, having solid moulded flesh, results in lower risk of the belt getting pulled in the gap between pelvis and thigh. This specification was preferred by the Child Safety Working group over the existing foam filled upper leg flesh. Lower legs with smaller feet allow for better positioning of the dummy in cars with smaller space between rear and front seats.
Euro NCAP and Current Regulations
In 2016, Euro NCAP began dynamic performance assessments which included the use of Q10 and Q6 Dummies.
Current Regulations using Q10:
• Euro NCAP Assessment Protocol – COP v7.01
• Euro NCAP and KNCAP – Offset Frontal Impact
• Euro NCAP and KNCAP – Barrier Side Impact
• UNECE R129
Certification and Recalibration
All of Cellbond’s Q10 dummies are certified to ISO 17025 by Cellbond’s in-house ATD Test Lab.
We offer recertification and recalibration services, and also have test fixtures and probes available to purchase.
Each Q10 Dummy is supplied with a comprehensive Technical Manual in hard copy and PDF format as part of our commitment to after-sales service.
