The Sliding Safety Hinge Assembly (SSHA) minimizes the degree of personal injury or discomfort that could result from accidental closure of the lid of a box, i.e. “toy box”, by pinching a finger between the lid and box, particularly as the obstruction approaches the side or rear of the box near the hinge.
