The driver side, curtain airbag deployed incorrectly. The airbag deployed at an angle. Instead of the airbag going down to provide a barrier between the window and the driver, the air bag slid to the right hand side of the driver's head. This meant that the driver's head was squeezed between the window and the airbag for two or three minutes until the airbag deflated. The car seat airbag was deployed as well. The collision happened at a 30 degree angle. The driver was stopped and the oncoming driver was traveling 10-15 mph. The rear door on the driver's side was struck and was the only door damaged. No windows were damaged. The vehicle is a total loss and is being towed by the insurance company to be auctioned and salvaged.
