During an accident, the front driver side was impacted. My brother was driving, and hit his head on the windshield after air bags failed to deploy. He rear-ended another vehicle on the highway when he was going somewhere around 40-50 MPH. He is handicapped, and therefore was seat belted into his wheelchair in addition to the car seatbelt. It is believed that his chair seatbelt kept him from hitting his head harder or from permeating the windshield. Pictures included below show his van (white) and the vehicle he hit (grey/silver) with the rear end damages.
