Firefighters are exposed to high levels of physical stress. This is due to complex, long missions and the necessary protective equipment and rescue tools they use. As a design concept close to the market, the “exo air+” demonstrates how exoskeletons will soon be able to support firefighters. The exoskeleton was designed to relieve pressure on the lower back. When the upper body is bent, the mechanical exoskeleton stores energy and releases it in a supportive manner when the body is straightened. Reducing the strain on the body can prevent later health consequences in an increasingly aging society and enables professionals to work longer. The exoskeleton can be equipped with modules on the back, such as an air cylinder for breathing protection and special equipment for forest fires or disaster rescue. The design focused on high adaptability and intuitive handling.
