The Differences between Car Seat R129 and R44 Safety Certificate

in News

When it comes to the safety of our little ones during car journeys, there’s no room for compromise.  Parents and caregivers need to know about car seat safety standards. Two common ones are the R129 and R44 safety standards. Let's look at how they're different.

R44 Safety Standard:

The R44 safety standard has been established for several decades and has undergone various phases, each designated by a number (e.g., R44-03, R44-04, etc.). 


R129 Safety Standard (i-Size):

The R129 safety standard, also referred to as i-Size, signifies a more contemporary advancement in child car seat safety regulations.

R44 vs R129(i-size): What is the difference?

1. Advanced Crash Dummies

ECE R129 testing uses new and advanced technology crash test dummies with more sensors than older dummies.

2. Side-Impact Certified

R129 introduces pioneering side impact testing standards, alongside frontal and rear crash tests, to enhance head and neck protection for children. Under R44 car seats primarily undergo frontal impact testing, focusing on shielding children in head-on collisions, without including side impact testing.

Notes: Side-impact crashes account for approximately 20% of all accidents

3. Rearward Facing Longer

R129 emphasizes extended rear-facing travel, is considered safer in collisions, and recommends children to remain rear-facing for longer periods until at least 15 months and a minimum of 76cm to allow more time for children to develop their next strength. 


4. Better Fit Formula

R129 differs from R44 by prioritizing the height of the child overweight, simplifying the selection process and ensuring a better fit. This focus on height aims to accurately accommodate growing children.

Notes: Children should use car seats until they can safely use the vehicle seat belt independently, typically around 150cm tall. 


In conclusion, while both the R44 and R129 safety standards aim to enhance child car seat safety, they differ significantly in their approach and requirements. The R129 standard, with its focus on height-based classification, extended rear-facing, side-impact testing, and compulsory ISOFIX installation, represents a more contemporary and comprehensive approach to child passenger safety. 


However, it's important to note that R44-certified seats remain legally acceptable in many regions and still provide a high level of protection when installed and used correctly. Parents and caregivers should carefully consider their needs, and the regulations in their area, and choose a car seat that best meets their child's requirements and safety standards.
