crazy_ugly_coyote Posted June 17, 2008 Share Posted June 17, 2008 Cause I am so tall I have to have my seat flush mounted to the floor. The car is a track only car that gets taken out on the street whenever I feel squirly. I need to know if this would be a legal setup for a DE3 car The seat is a Recaro Seat out of an Evo Quote Link to comment Share on other sites More sharing options...

NOT///MPOWER Posted June 17, 2008 Share Posted June 17, 2008 Hope this helps... 11.4.8 Seatbelts and Harnesses The seatbelts should be in good condition. No damage may be present on the seatbelts and they must be the factory configuration. Any harness or any restraint system, other than factory stock, shall conform to CCR section #15.5, in all respects* except for the expiration regulations. Harnesses that are expired for racing may be used providing that they are in at least very good condition. The use of a lap belt without any shoulder restraint is not permitted. Passenger seatbelts must meet the same minimum requirements per the CCR as the driver seatbelts if being used by a passenger. Notepassenger equipment need not match the installed equipment on the driver’s side. *Aftermarket DOT-certified belt sets, installed to the manufacturer’s specifications may be allowed. Proof of DOT certification and proper installation is the driver’s responsibility. 15.5 Driver restraint system (See diagram at end of section) 1. All vehicles must have a five (5), six (6), or seven (7) point seat belt system. Arm restraints are required in open cars and cars with: Open T-tops, Open Targa tops, missing moon/sun roofs, or glass moon/sun roofs. 2. A five (5) point system consists of: a three (3) inch lap belt, two shoulder belts that are either two (2) or three (3) inches wide, and a two (2) inch anti-submarine strap. 3. A six (6) point system is recommended for cars where the driver is seated in an upright (to thirty (30) degrees) or a semi-reclining position. It consists of two (2) anti-submarine belts in addition to lap and shoulder belts. Note: Current FIA Approved belt sets with two (2) inch lap belts are acceptable with the six (6) point system. 4. A seven (7) point system is recommended for seats with more than thirty (30) degrees of incline. Note: Current FIA Approved belt sets with two (2) inch lap belts are acceptable with the seven (7) point system. 5. The material of all straps should be Nylon or polyester, and in new or perfect condition. The buckles should be metal quick release. There should be a common release for all belts. [Note: Certain Momo brand belts were recalled by the manufacturer. These are NOT suitable for racing.] 6. The shoulder harness shall be mounted behind the driver and above a line drawn downward from the shoulder point at an angle of no more than twenty (20) degrees with the horizontal. 7. The seat, seat holes, and attachments to the seat are not permissible “harness guides” for compliance with the angle requirement. Only specific harness guide bars, or parts of the chassis or the cage are allowed to be used for this purpose. The guide bar, if used, should not present a sharp edge to the belt. It should provide as much area of support as possible to distribute the load. 8. Only separate shoulder straps are permitted. “H” type belts are allowed. “Y” type belts are not allowed. Each shoulder strap must have an independent mounting point. 9. All mounting hardware should be SAE grade five (5) or better. Large diameter mounting washers should be used to spread the load. Bolting through floor panels etc. is not acceptable without required washers. 10. All belts should meet at least one of the following: A) SFI Specification 16.1 or 16.5 (for use with HANS only) and shall bear a dated label of no more than two (2) years old. At least one date label is required on belt sets. B) A restraint system meeting FIA spec #8853/1985, 8853/98, or D-###.T/98, including amendment 1/92 may be used. FIA certified belts have a label that shows an expiration date. The belts cannot be used past December 31st of the year shown on the label. At least one date label is required on belt sets. 11. All drivers should take care to ensure that their belts are properly worn, adjusted, and latched. “Cam-lock” type belts can be subject to inadvertent release, should the driver fail to ensure that they are properly latched. 58 12. Any driver involved in a high impact crash shall send all of their safety belts back to the manufacturer for inspection, re-webbing if necessary, and re-certification before they may be used again in competition. Proof of re-certification is the driver’s responsibility. 13. All belts should be threaded to the manufacturer’s instructions. An example of one type of threading instruction set appears at end of this section. Quote Link to comment Share on other sites More sharing options...
Bruce L. Posted June 17, 2008 Share Posted June 17, 2008 Just to be clear - this statement is not accurate - Fritz posted the correct rules. Once you modify the factory belts, you have to conform to the rules for harnesses. It'll pass tech, most likely..... To the OP, you need to have that 5th attachment bolt behind the slit in the seat. If it is in the position you're showing, in an accident, your submarining weight will just rip the front part of the seat off. cheers, bruce Quote Link to comment Share on other sites More sharing options...
HBennett Posted June 17, 2008 Share Posted June 17, 2008 leggwork is correct. If you are going to mount the substrap in front of the seat (not a good idea), don't bother screwing up your seat, just run it in front of the seat (again, not a good idea). Since it looks like you are modifying a stock seat for a 5 point system, how do the shoulder straps run, through pass thru's built into the upper part of the seat back or around each side of the headrest (not a good idea)?

crazy_ugly_coyote Posted June 18, 2008 Author Share Posted June 18, 2008 This is how the shoulder harnesses come through the seat So as long as the 5th point is mounted behind the seat everything will be kosher? Quote Link to comment Share on other sites More sharing options...
NOT///MPOWER Posted June 18, 2008 Share Posted June 18, 2008 What are you planning on attaching the shoulder straps to? Keep in mind that the mounting point of the shoulder straps need to be mounted at an angle no greater than 20 degrees downward from the pass thru on the seat. Otherwise you'll risk compression of your spine in an impact. Are you using a roll bar, or cage? If so, it is not a good idea to use a reclining seat.

NOT///MPOWER Posted June 18, 2008 Share Posted June 18, 2008 Ok.. Well, I'm not an official of any kind, but my understanding is that this restraint "system" (i.e. seats, roll bar/ cage, harnesses) are just that. A system. You should keep all components of the system together. In a rear impact situation, the seat-back reclining mechanism could break allowing the seat-back to recline, and thus allowing your helmet to come in contact with the roll bar. In addition, since harnesses do not automatically tension, you could come out of the harness with no support from the rear. IMO, you should be using a fixed-back seat. Please take a moment to contact whoever is in charge of tech & safety for your region. (I don't recall which region you're in) but for MA it's Jim Politi, aka "Grumpy".

Izzy's Cages Posted June 18, 2008 Share Posted June 18, 2008 ... also, the sub mounts shouldn't go "behind the seat"... as Leggwork said...behind the opening in the base of the seat... so about 15-20degrees rearward of the opening. IMO, sell the Evo seats and buy a fixed back seat Quote Link to comment Share on other sites More sharing options...
HBennett Posted June 18, 2008 Share Posted June 18, 2008 leggwork did say behind the slit in the seat, not behind the seat. In actuality, the slit should be "real" close to the crotch so that the sub-strap comes down in line with the sternumm, then mounted slightly behind the plane of the sternum, essentially behind the slit in seat. By the way, most "race" seats do not have the slot for the sub-strap in the correct position. They are a good bit forward from where they should be for most racers.
