Comparison... 2004 vs 2006

Jabberwock,
I thought this might be of interest to you since it impacts the laminated glass design on vehicles and may make it more difficult for someone to extricate themselves from a vehicle in a crash similar to the two accidents you mentioned...
"Side-window ejections are the focus of a new federal motor vehicle safety standard, No.226. The proposed ejection mitigation safety system will reduce the partial and complete ejection of vehicle occupants through side windows in crashes. Standard No.226 would apply to the side windows next to the first three rows of seats in motor vehicles with a gross vehicle weight rating (GVWR) of 10,000 pounds or less. NHTSA is proposing a test in which an impactor would be propelled from inside a test vehicle toward the windows. The system would be required to prevent the impactor from moving more than a specified distance beyond the window. To ensure that the systems cover the entire opening of each window for the duration of a roll-over, each side window would be impacted at up to four locations around its perimeter at two time intervals following deployment. NHTSA anticipates manufacturers would meet the standard by modifying existing side-impact air bag curtains and possibly supplementing them with advanced laminated glazing. The curtains would be enlarged so they cover more of the window opening, made more robust to remain inflated longer, and made to deploy in both side impacts and rollovers. In addition, they would be tethered or otherwise designed to keep the impactor within the vehicle."

As I read this it seems to be talking about larger side and curtain airbags that also stay inflated longer ... is that correct?
Very interesting info. I did not realize ejections were a problem anymore unless you aren't wearing a seat belt.

I believe so... This caught my eye too because I think it points to them making the windows more durable/less prone to breakage..."
