I'm an Oregon attorney, and I can tell you that it sounds like the driver of the car is liable for your injuries. You may have *some* comparative fault because of riding on the sidewalk, but we would need to look into that further before being sure.
You can give my firm a call and get a free consultation - our number is (503) 592-0606. I used to work FOR the big insurance companies, so I know how they run their side of things.
If you have a good case and the driver has insurance, the insurance company will likely want to settle the case with you out of court. You'll probably get a much bigger settlement if you've got an attorney who knows what he's doing!
You have a claim, and should see an attorney with experience in this area of the law. However, since in general it is unlawful to ride a bicycle on the sidewalk, you have some fault as well. The relative fault of each party determines what you might recover, or whether you may recover at all.
