A body harness is designed primarily to distribute fall-arrest forces across multiple areas of the body, ensuring safety and minimizing injury during a fall. The harness typically focuses on the shoulders, upper back, and chest to effectively spread the impact of the fall.

In terms of design and function, the lower back does not play a significant role in the distribution of fall-arrest forces. Instead, the harness is engineered to channel forces toward more robust areas of the body, such as the stronger muscle groups located in the shoulders and chest. This distribution helps to protect vital organs and vulnerable regions during a fall, while the lower back generally bears little of that force and is not intended to absorb shock in such scenarios.

Understanding this aspect of harness design is crucial for maintaining safety in fall protection systems. It highlights the importance of proper harness fitting and use in ensuring that forces are effectively directed to prevent injury.
