Right Interior Nets
Right Side Interior Nets. We view Right Side Nets (also called "Cage Nets") as a mandatory piece of safety equipment. In an impact, the body moves forward 6-8 inches. This is normal and quite necessary to prevent injury. The harnesses stretch to decelerate the body. If you are in an offset impact (an impact that is not straight on) there are high lateral forces that will move you side to side. If you do not have a Right Side Net, it is very easy for the body to wrap around the side of the seat when the harnesses have stretched.
A Right Side Net prevents this by guiding your head and shoulders back into the seat keeping you from painful injury.
For the untimate in safety to minimize the driver loads in an impact, let's build the best driver safety system we can.
Frontal Impact: First, let's make sure our driver has a frontal head restraint (like a Hans Device, Schroth SHR Flex, Simpson Hybrid etc) to limit forward movement and control neck angles, and a correctly installed 6 point harness.
90° and Direct Rear Impacts: For the 90° side and direct rear impacts, let's have a properly fitting head containment seat.
Less than 90° Impacts - Left Side: For angular impacts less than 90° where the driver's upper torso may stretch the belt system to where the helmet may leave the head containment surrounds, we contain the driver using the left side window net or if the distance is greater than we like, we offer cage nets for the left side also. The window net is to prevent debris from entering the vehicle and keep the driver's arms & hands contained. If the left side net is too far, a left side cage net (used in all pro sedan race cars) is a great addition to your safety system.
Less than 90° Impacts - Right Side: For angular impacts less than 90° where the driver's upper torso may stretch the belt system to where the helmet may leave the head containment surrounds, we contain the driver using the right side containment, also called cage nets, to keep the driver's head and upper torso movement limited. It is also a great wrist/hand/arm catcher in high load impacts where the driver's hand pivots off the elbow and moves inboard. The right side cage net will also limit this movement.
Common sense and the understanding of your rule book will save you from a nightmare at trackside tech the morning before your first race. Build the safety category correctly once and enjoy many safe and fact race laps.
