Q-Series Q3s Dummy
- Standard Q3s ATD 020-0100
In the early 1990s, statistics showed that there was much room for improvement in the design of child restraint systems (CRS) in vehicles. The existing P-Series of child dummies used for testing CRS had a simple design and were limited in their measurement capability.
Our Q-Series of child dummies were developed in 1993 as successors to the P-Series in the hopes of giving engineers the information they needed to design greater impact protection for children in cars. This new generation of dummies has much better anthropometry, biomechanics, and kinematics, all key to better evaluating the risk of injury to varying ages and sizes of child passengers. The Q-Series can be used in frontal or side impact testing, and the instrumentation is interchangeable within the dummy series.
The Q3s is a side impact only adaptation of the Q3 dummy designed to complement the Part 572 Subpart P Hybrid III 3-year-old child dummy.
