Let's consider for a moment the critical nature of seat belts/shoulder harnesses in the modern race car. Whether it is a sprint car, stock car, or an Indy car, the role is the same--keeping the driver in the seat (hopefully, a properly constructed one), using the pelvis and shoulder structure to help control the body as the car accelerates, decelerates, and changes direction.
It is critical to pay attention to your belts, how they are installed, and how they are worn. You need to check the dates on the lap belts and shoulder harnesses at the start of every season...if you drive more than one car, then have a plan to check them routinely. Most sources agree that your restraints should not have seen more than their 3rd year since manufacturing...and that is under good conditions. Exposure to sunlight, exposure to chemicals and dirt (pay attention dirt-trackers!), points of abrasion, and use during a previous significant crash all will shorten their useful life. Please note...racing restraints are really only intended to do their job once! If they have done their job well once...allow them to be retired with dignity...there is no economy in continuing to use "abused" belts.
Details of installation are important. READ THE DIRECTIONS! What the belts are mounted to, the angle compared to the drivers body, how the belt passes through the seat, how and where the shoulder harnesses are mounted, where adjusters are placed...all play huge roles in how well the restraints will perform. Do not hesitate to call the manufacturer to help you make sure you are using their product in the best and safest way!
We will discuss safety restraints in more detail in later entries....this is an important subject. If you have any doubts, please...ask!
Remember to say thanks to your local safety team...they care about you!
