Ctrp 1204 Safety Tech The Perfect Fit 004

"I believe that as many as 90 percent of the injuries in racing are preventable."

That's Brian Butler, the owner of ButlerBuilt Professional Seat Systems, talking, and he should know. Butler has been at the forefront of almost all of NASCAR's safety initiatives since Dale Earnhardt's tragic death. He has also done extensive research into the types of injuries that happen at short tracks across the country. This includes the way both the tracks and cars are constructed, the safety equipment used, the average skill of the drivers, and the speeds reached.

And the answer, unequivocally, is that injuries can--and should--be decreased dramatically.

"When I go to tracks or work with racing teams, it's surprising how often you can find an issue, either with the seat or how it's mounted or something else completely," he says. "There's no argument that any person that gets into the driver seat is completely responsible for ensuring his own safety, but I also take issue with the racetracks.

"At most Saturday night tracks the only tech is to see how big the carburetor is or how much the car weighs after it pulls off the track," he continues. "Too few racetracks do an honest tech for safety, and that's a shame. Because when tech is non-existent, the racer is led to believe that everything is OK.

"You don't have to check every single car every single week, but it doesn't take too many resources to check one or two cars every week. Let the racers know what you are looking at and what's important. That way tracks can lead the way in making sure that when one of their guys gets in a wreck, they are doing everything possible to make sure he or she walks away from it without a serious injury."

A campaign to improve the safety tech programs at racetracks across the country is a bigger project than can be accomplished in just a single article, but we did want to share this just to get you thinking. We'll be sharing from Butler in the future about how to make sure your own racing program as safe as possible, but right now we'll be concentrating on the main piece of equipment that connects you directly to your race car--your racing seat.

A good quality, aluminum racing seat is not only a major component in the overall safety system, but it's also very important in terms of your results on the racetrack. A racing seat should be properly sized and mounted in the car so that it maintains your body position so that you aren't sliding around and have to exert energy and focus on holding yourself in the right spot; it's mounted so that you have good sight lines and are within easy reach so that you have good leverage on the steering wheel, the shifter, and the pedals; and it provides a good connection to the car so that you get that "seat of the pants" feel to help you know what the car is doing.

These three considerations, along with the important fact that a properly fitting seat will do a better job of protecting your body in the event of a crash, is why it's worthwhile to take the time and make sure the seat you mount in your race car is the right match for your body type. Most reputable seat manufacturers will have a variety of seat sizes that they stock to fit different body types, but if you can't provide them the proper measurements there is no way for them to know which seat will fit you the best. And even then, an off-the-shelf seat doesn't guarantee that it will be the best fit for you. Sometimes, the best option is to invest in a custom-built seat both for your safety and your ability to concentrate on racing without distractions from inside the cockpit.

Amazingly, Butler told us that he will change his seats based on the angle of recline on which it will be mounted. Over years of working with countless drivers, many in the NASCAR Sprint Cup Series as well as the top Dirt Late Model drivers, Butler says that as a general rule having the seat reclined 20 degrees from vertical provides the best opportunity to feel what the car is doing. Sometimes, depending on the style of car and the driver's height, that angle must be adjusted, but generally, Butler likes to keep the seat angle within 5 degrees in either direction (15 to 25 degrees back from vertical). The rest of the seat is built off of this angle.

We followed along as Butler fitted racer Jason Gulledge for a new seat that will go into a Super Street race car that he's building. Other manufacturers may have instructions that vary slightly, but the concept is still the same. We'll follow up later as Gulledge installs the seat in his car, but the first step is to get the seat that best fits your body. Even if you aren't anywhere near a manufacturer so that it can fit you, here's how you can have someone help you get the measurements you will need to provide.

    1 Brian Butler (right) walks us through the process of properly measuring a racer for a seat. Thick clothing can throw your measurements off, so the racer should have on nothing thicker than a T-shirt. You don’t need to account for the thickness of a driving suit because it will compress. Begin by having the racer sit on a table top or counter where their legs can hang freely.

    2 Make sure nothing is in the racer’s pockets and have him or her sit with their knees approximately 8 to 10 inches apart to mimic having their feet on the pedals. Now measure the width of the hips in a straight line across the groin area from the outside of one thigh to the same point on the opposite thigh.

    3 Measuring in a straight line is critical for all of these measurements. Butler stresses that this is not like being fitted for a driving suit. All the seat dimensions are on a flat plane, so if you allow your tape measure to bend like you see here, your seat will wind up way too large. In fact, Butler recommends that if you’re making your own measurements, use a yardstick, a framing square or some other rigid measuring tool. This will help ensure your measurements are as accurate as possible.

    4 To measure for the seat back height, the driver should be sitting with his or her absolute best posture. Once you are strapped into a racing seat properly, your back is pulled into the back of the seat, so while being measured the driver should sit with his back as straight as possible.

    5 It’s too hard to get the best measurements if you have the driver mimic holding a steering wheel, so just have him hold his right arm out and bent like so with the left hand resting comfortably in the lap. Butler says some people have a natural tendency to favor one side or another when sitting—especially when one arm is raised—so take a moment to ensure their shoulders are level.

    7 If the driver’s arm is getting tired at this point, you can allow him to rest his hand on his leg like you see here. The next measurement is from the tabletop vertically to the top of the shoulder. This is for the shoulder strap, so measure to the meaty part of the shoulder near the base of the neck where the shoulder strap will sit. Remember not to allow your tape measure to bend, so you may need a ruler to mark a level line from the driver’s shoulder to the tape.

    8 The next measurement is the width of the driver’s shoulders measured across the chest. This is the widest point of the driver’s silhouette which should be somewhere halfway down the shoulder joint, not the top of the shoulder.

    9 Have the driver stand with his back to you holding his arms out at approximately a 30-degree angle. Place the tape measure 1.5 inches below the armpit and measure the width of the back in a horizontal line. Remember, for all of these measurements, make sure the driver isn’t flexing, making muscles or otherwise puffing themselves up to look cool. It may be good for the driver’s ego, but it’sn’t when it comes to getting the best possible fit for a racing seat.

    10 The last measurement is to determine the depth of the chest cavity. Have the driver stand with his back against a wall or smooth door. Again, the back should be flat against the surface from the hips all the way to the shoulders. Place the measuring tool underneath the armpit until it’s flat against the door or wall and measure to the front of the chest. The driver must be relaxed and not flexing or puffing out his or her chest for this to be a valid measurement.

    11 With these measurements ButlerBuilt or another reputable seat manufacturer should be able to place you in either the proper off-the-shelf seat or fabricate a seat specifically to your measurements. But there is really no replacement for actually sitting in the seat to check how it feels. Butler says that once they are in a properly fitting seat, many drivers will remark that the fit is tighter than they are used to. The fit should be snug but not so much that you will have trouble breathing. Remember, the feel will loosen up a bit as the padding conforms to your shape. A good test is you should never be able to fall right into your racing seat. Instead, getting past the side bolsters (also called rib protectors) should require just a bit of a wriggle. The shoulder supports should be just wide enough for you to slide your hand between the driver’s shoulder and the support—any closer could restrict the driver’s movement.

    14 ButlerBuilt’s head support system is the same it sells to the Sprint Cup teams and actually meets an SFI certification separate from the seat. The foam on the right side is built from three separate layers. The outermost layer is for comfort and allows the driver to rest his helmet against the support without transmitting vibrations from the car to the driver’s head. The next two layers are progressively stronger and designed to cushion the blow to a driver’s head in a side impact while also limiting movement.

We’ll get into this in more detail later, but we did want to point out that most reputable seat manufacturers including ButlerBuilt will offer ways to help you properly mount your seat in your race car. Don’t blindly trust the mounts your chassis manufacturer provided. It has to put them where the “average” driver will need them. ButlerBuilt offers these lower seat mounts that should be bolted to a seat hoop that is part of the rollcage and not the floor of the car.
