That area reflects a range of loads. In general, the tighter the better for most H&N systems.

"Webbing" applies to such products as the Hutchens, D-Cel, Simpson, etc., i.e a form of webbing network about the torso. These can perform well if worn tightly.

Some drivers loosen the straps on the HANS device, so the head loads increase.
