What does the term "suspension system" refer to in helmet design?

The term "suspension system" in helmet design refers specifically to the mechanism that connects the helmet shell to the wearer's head. This system plays a crucial role in how the helmet fits and functions. It typically consists of a network of straps, padding, and sometimes a cradle or harness that helps to stabilize the helmet on the head.

The suspension system is vital for providing comfort, as it allows for some adjustment to fit different head shapes and sizes. More importantly, it also enhances safety by maintaining the positioning of the helmet during use. This correct positioning is essential for ensuring that the helmet effectively absorbs and distributes impact forces, thereby providing maximum protection in the event of an accident.

While other options mention aspects of the helmet's construction or appearance, they do not capture the essential function of the suspension system in terms of safety and fit, which is why the understanding of this term is critical in helmet design.
