The family of a quadriplegic who died in 2007 has filed a lawsuit against a Tennessee-based wheelchair company, claiming their son suffered fatal injuries while they were repairing his wheelchair. According to the lawsuit, technicians with National Seating and Mobility were repairing Jeffrey Thompsonâ??s wheelchair when it suddenly jumped forward, trapping Jeffrey under a nearby table and severely injuring his legs. He died a few days later from complications caused by those injuries. The lawsuit accuses the technicians of failing to remove Jeffrey from the chair before they began repairs and forgetting to turn the battery off before they started. The lawsuit is seeking $10 million in damage
