Voici ce que j'ai lu sur carseat. Il s'agit d'un compte rendu d'une conférence sur la sécurité des enfants en voiture. Interessant non ?
We discussed best practice, how kids behave in cars, practical issues and what actually goes on when we take three or four kids to soccer practice in one car. What is a safe and practical solution?
Conclusion is that the backless booster is great in many situations despite its poor reputation. A backless booster basically provide the same protection as a high back booster according to research from real life collisions. We need to do a better job in advising parents which car seats offer the best practical solution.
We prefer the high back booster for younger kids, 4-6 years, but a high back booster is not necessarily better for older children. Main reasons are the larger sizes of high back boosters, behavior by todays children and better flexibility of backless boosters.
