R3 Overview and related test material

From Trackpedia

The R3 looks like a carbon fiber cross. The cross goes against your back and kevlar straps secure it to your chest. It requires D rings to be installed on your helmet. It's SFI 38.1 certified. It works in a car with a 3pt belt also.

This device works well for instructors as you wear it and it works with both 6pt and 3pt belt systems, although whether anyone needs a device when the body is not really restrained has not been proven.
