The teardrop-shaped protective structure was developed based on engineering and ergonomic studies focused on the efficient distribution of loads and impacts. Its geometric design, characterized by one wider end and one tapered end, allows energy to be progressively dissipated, reducing stress concentration at specific points of the structure. In addition to its mechanical efficiency, the teardrop design enhances the ergonomics of the equipment, adapting better to the user’s handling and movements without compromising mobility. Due to these characteristics, it is widely used in protective systems for operational, rescue, emergency, and safety environments.
