Over-the-shoulder restraints are safety devices used to secure individuals in various settings, such as vehicles or medical equipment. They typically consist of straps that go over the shoulders and across the chest, helping to prevent movement and ensuring the person's safety during transport or treatment. These restraints are commonly found in ambulances, aircraft, and roller coasters, where maintaining a stable position is crucial. They are designed to be adjustable for comfort while providing adequate support, reducing the risk of injury during sudden stops or changes in direction.
