Abstract: An Improved Bus Seat Safety Restraint is disclosed. The preferred safety restraint comprises a padded U-shaped bar that has indexed stops at stowed, in-use and lower locked positions. The bar locks and restrains the passenger when the vehicle experiences a side or front collision, or if the vehicle rolls over. The bar preferably has a single, fixed pivot point. The bar further comprises a padded thigh pad that is height-adjustable to provide greater comfort to a wide variety of body shapes and sizes. Still further, the restraint bar system is installable and easily aligned on both new and existing buses and other mass transportation vehicles.
