The Profi II-6 HANS features the 2" lap Flexi Lap Belt, the T-bar sub strap and HANS specific 2"/3" shoulder belts. The HANS specific shoulder belts are designed to make HANS use safer and more comfortable. The belts start as 3" webbing at the cam lock, then after the length adjuster they are 2" webbing which fits completely on the HANS yoke. This gives you the optimal force distribution, entirely on the surface of the HANS. A standard 3" belt will work, however some of the load is not distributed on the HANS. This also can be a comfort issue with some of the webbing falling off the HANS.
Another important feature of the HANS specific shoulder belts is the ability to move the anchor points towards each other to acheive the perfect installation geometry. This will help in the Post-Impact phase - very important in a roll-over situation as well.
The main premise behind the 2" lap belt is one of added safety. A 2" belt rides within the crest of the human pelvis where a 3" belt would rest on the edges. This allows you to get the belt up to an inch and a half tighter. That means the lap belt will be working earlier in the accident event because it gets loaded faster. It's also more comfortable and easier to adjust becuase there's less friction through the adjuster.
Another feature unique to the Profi Series 2" lap belts is the "Flexi Belt". The End Fittings and Cam Latches are wrapped into the harness, making it so that the lap belt can be changed from a Pull Up configuration to a Pull Down. This allows you to set the belt up just the way you want it for your specific situation. It also allows for Bolt In brackets to be wrapped in for the lap belts if needed. Snap in brackets come standard on the laps.
Comes with Snap-In attachments at Lap and Sub points. The Shoulders come ready to be wrapped around a roll-bar. Available in Black, Blue, Red
