Maximum 300mm seat to seat belt mounting points
If passenger seat fitted and no passenger in race, seat belts and window net must be removed or correctly buckled and/or attached.
Harness to be fitted to manufacturer’s specifications or for existing fitment the following guide lines.
See “Installation of Restraint System”. [Fig. 1 and 2].
In order for the driver restraint system to be fully effective, considerable thought must be given to the location of mounting points and to proper installation. Many installations comply only with the letter of the rules with no understanding of the needless injury to the driver.
The mounting points should be solid and should remain so even if this vehicle is deformed due to an accident. The mounting points should also not put undue strain or twist on the belt system hardware. The lap belt should be positioned so it rides across the solid pelvic area and not the soft stomach area or down on the thighs.
The shock absorbing ability to protect internal organs makes it the preferred location for the belt. (See diagrams)
The shoulder harness should be mounted to prevent the driver from moving upward, out of the seat, in the event of a rollover. The required minimum distance from the top of the driver’s helmet to the top of the roll bar does not leave much leeway for the shoulder harness to prevent the helmet from striking the roof in the event of a rollover. The shoulder harness is the major means of preventing injury in such an accident.
Anti-Submarine straps serve two purposes.
To secure the lap strap down across the drivers hips, so in the event of an accident, it is not pulled up across the stomach by the shoulder straps.
To prevent the driver from sliding forward and out of the harness [see Fig.2(i) and Fig. 2(ii)]
For extra assurance a double strap anti submarine belt can be used [see Fig.2(iii) and Fig.2(iv)]
When the driver is seated in a semi-reclining position a six point system (two anti-submarine or crotch straps) is preferable. Most drivers find the two anti-sub strap position more comfortable regardless of the type of car.
In many instances, the anti-submarine straps are mounted much too far forward of the seat. This practice could cause injury as the body can slide partially out of the seat before being restrained when the strap contacts the groin. It is much more practical to cut a slot in the seat bottom so the anti-submarine strap can be anchored in line with the chest.
Because of difference (often vast) in competition vehicles, “standard” method of mounting is impractical.
Good judgement and common sense in inspecting restraint system mounts is needed. Safety equipment is often neglected in favour of performance equipment, but its proper operation when the need arises is essential to survival.
On board fire extinguisher optional. It must be securely mounted and be of the correct type for the fuel being used.
Numbers 1, 2 and 3 reserved for VSC State Title placegetters. All vehicles are to be presented for racing in a good condition, including paintwork and sign writing. Allocated numbers may be painted on the both sides of body
