| Driver and passenger front air bags, plus a safety belt tensioning system that tightens the belts within milliseconds of a crash. |

| With a pang and a ping and a scrunch not unlike the sensation you get when a tooth is pulled, the glass shattered the moment the tensioning springs were released. |
| A snowcat's main frame is mounted on support axles that act as the vehicle's suspension mechanism, the front axle also tensioning the tracks. |
| Another addition is a tensioning damper that must work whether the unit is cranking the engine or generating power. |
| This is precisely the idea behind many of the market's frameless stencil tensioning systems. |
