US Patent 8113760 Secure loading system

A secure loading system operates with a wheelchair lift attached to a vehicle, securing the wheelchair to a platform during the lifting motion and retracting the platform into the vehicle once the wheelchair has been lifted, or performing a reverse operation wherein the platform is extended to the lift for lowering the wheelchair. The secure loading system may be an after-market add-on to a lift, or may be integrated into the lift at design time. The system may also be adapted for many other embodiments wherein a secured platform is needed during a lifting motion.
