Driver Restraint System Installation
The following diagram is a generic instruction sheet utilized by a number of different manufacturer's and covers the basics of installing a driver restraint system, hereafter referred to as the "install diagram".
3-bar Slides
Regardless of the mounting style - wrap-around, bolt-in, or snap-in; and regardless of whether the mount in question is for a lap, anti-sub, or shoulder belt, if the belt uses a 3-bar slide there are two critical rules that must be observed in order for the belt to function properly.
First, the 3-bar slide MUST be located as close as possible to the anchor plate or bar around which the belt is wrapped.
Second, the belt MUST be wrapped back a fourth time through the 3-bar slide to prevent the belt from loosening in the slide.
To put on the restraint:
Loosen the lap and shoulder belt tilt-lock adjusters.
Place the left shoulder belt buckle on the link.
Place the anti-sub strap buckle on the link.
Place the right shoulder belt buckle on the link.
Pull up on the hammer and insert the link into the latch until it is engaged by the hook on the end of the hammer.
Press down firmly on the hammer until it clicks into place.
If equipped, fasten the latch guard to the lap belt velcro.
Centre the main buckle on the body, ensuring that the lap belt rides in the pelvic crest between the upper thighs and the pelvic bone.
Make sure the anti-sub belt is snug with the main buckle in this position.
Securely tighten the lap belts. Don't be shy - get 'em nice and tight.
Tighten the shoulder belts with their tilt-lock adjusters.
Check that tightening the shoulder belts has not pulled the lap belt out of position. If it has, the anti-sub strap and / or lap belts will have to be tightened more first. Loosen all tilt-locks and begin again at step 8.
Check the position of the shoulder belt tilt-locks. They should be located approximately inline with the bottom of the sternum (breast bone). This should place them at least 10" below the clavicle (shoulder blade). If the shoulder belt tilt-lock is positioned too high on the body, it may ride up and cut into the driver's neck during a crash. A too-high shoulder belt tilt-lock also increases the chance of a clavicle (collar bone) fracture in an impact. If the shoulder belt tilt-locks are not properly positioned and the shoulder belts use a 3-bar slide at the anchor point, you can adjust the shoulder belt length as required to achieve proper tilt-lock positioning. If they do not have 3-bar slides (i.e. the anchor points are sewn in), you will have to re-do the shoulder belt anchor points on the chassis.
With all belts securely tightened and properly positioned, fasten the sternum strap, if so equipped.
A properly fastened main buckle will look like this.
Consequences of Wearing the Restraint Too Loosely:Any driver restraint should be worn properly tightened. Some of the possible consequences of wearing the restraint too loosely during an impact or crash may be:
Loose shoulder belts result in increased upper torso movement, increased head movement with resulting neck strain, and increased risk of contact with steering wheel or other objects in the cockpit. Contact inside the cockpit leads to injuries.
Loose lap belts lead to increased pelvic movement and resultant risk of submarining or ejection from the vehicle as well as placing extra load on the anti-sub strap; possibly exceeding its load capacity and causing it to break.
A loose anti-sub belt allows the lap belt to ride up, seriously increasing risk of abdominal injury, as well as increased risk of submarining and ejection.
Bottom line, when the belts are too loose the driver will not be properly restrained and in a crash or impact the result can be severe injury or death.
Remember to Buckle up; it just might save your life some day!
