DE modifications and harnesses

[Brian Minkin]

Dave,

5 or 6 point harnesses are part of a complete saftey system that includes seats with proper holes to allow the harness to pass through the seat. You can not use harnesses with a stock seat since the stock seat does not have holes for the shoulder harness, lap belt or sub belt.

See the national PCA policy below

8.As stated by National, a properly installed 5 or 6 point harness will require several changes to the automobile to create a safe occupant restraint SYSTEM. Harnesses must include a submarine strap and be mounted in an approved manner consistent with PCA Club Racing requirements and the harness manufacturer's instructions. A seat designed to be used with a harness must be properly installed in accordance with the seat manufacturer's instructions. A seat designed for use with harnesses will have holes allowing for the correct routing of the harness, both through the back and base of the seat for the respective shoulder, lap and anti-submarine belts. Shoulder straps should be mounted at 90 degrees to the axis of the occupant's spine or at most 40 degrees down from horizontal. In most installations this will require the use of an approved "harness guide bar or harness truss". As the addition and use of a properly installed 5 or 6 point harness places the occupant in a fastened and upright position in the vehicle, a properly installed padded roll bar or roll cage is strongly encouraged to complete the SYSTEM. The use of one without the other may result in an unsafe occupant environment and is not a complete SYSTEM.
