I was traveling at eastbound at 25 mph and entered a controlled intersection in manitowoc, Wisconsin. A motorcyclist traveling northbound approaching speeds of 60 mph ran a yield sign and T-boned my 2009 Toyota Matrix S 5 spd manual in the back passenger door and back quarter panel. The force of the impact spun my Matrix 180 degrees so I ended up facing westbound at the curb. The passenger-side curtain airbag deployed. However, the driver's side curtain airbag failed to deploy and I ended up with a mild head injury and a sprain/possible dislocation of my left shoulder from where I struck the inside of the vehicle. My concern is why the driver's side airbag curtain failed to deploy when I was T-boned by a motorcycle at 60 mph turning my car 180 degrees to face the opposite direction I was traveling. In my opinion, based on the impact, my side curtain air bags should have deployed as the direction and force of the impact would obviously force my body in the same direction, North, into the side of my car; the same direction the motorcycle was headed. The failure of my driver's side curtain airbag deployment led to a head injury and a shoulder injury; possibly a dislocation of my shoulder. I am awaiting the radiologists review of the X-rays taken today at Aurora health care center on reed avenue in manitowoc, Wisconsin. Toyota should take my concerns seriously and investigate the air bag systems in their 2009 Matrix models.
