The Tummy Shield™ is a specially engineered, patented and tested, single-piece more than 6 lbs. stainless steel assembly (plate and hook) molded inside a comfortable cushion and cover, which meet non-flammability requirements. The entire assembly is restrained with a webbing strap made of the same type of webbing as seat belts (just a smaller version), which wraps the vehicle seat and is secured with a buckle. The webbing strap is there to restrain and transfer the momentum energy of the Tummy Shield™ itself to the vehicle seat structure; thereby minimizing any crash force energy pushing pushing the lower extremities out from under the seat belt, an action called submarining.
