Actually, The Simpson device isn't strapped to the cage, but to my body. The harness is first strapped on not unlike an old WWII parachute harness, with two D rings about midway down my shoulder blades. The attaching straps are hooked there and the quick disconnect links are hooked forward to the cable loops on the helmet[by my ear lobes]. They[in theory] limit the helmet forward travel and do not require any additional steps to exit the vehicle. A good picture is available on Simpson's web site. While not as sophisticated as the more expensive carbon fiber systems, they would seem to work. It does pose one more step when getting suited up, however. None of the devices are effective in reducing the forward movement of the upper helmet/head, thus putting great strain on the anterior neck muscles.Some sort of blade restraint that would be in front of the area above the top of the visor area of the helmet that is somehow released when dropping the door net or releasing the seat belt system,so as not to create an extra step when exiting the vehicle, would solve that problem. Somehoe we need to keep it simple.
