Hank Posted June 2, 2009 Share Posted June 2, 2009 I just bought a pair of G-Force 6 point harnesses for my MEGABUSA, and I'm looking to see if anyone out there has a picture or 2 of the hole(s) required in the seat bottom to pass the crotch straps through. Looking to see if I should cut more of an oval or a triangle or what. Thanks in advance! Credit card got warm today: (2) G-Force 6 pt harnesses (2) snaphooks for shoulder belts (2) arm restraints Simpson Diamondback helmet (thank The Stig) Iridium helmet shield (helmet comes with clear shield) $1000, ouch! Racing is expensive. And to think, I haven't even bought gloves, a suit, shoes, HANS device and fire suppression system yet! Link to comment Share on other sites More sharing options...
slomove Posted June 2, 2009 Share Posted June 2, 2009 .......$1000, ouch! Racing is expensive......... All relative.....I heard some of the Formula 2000 folks here spend up to $15,000 per race weekend. Big rig truck, spare cars, a handful mechanics and umbrella girls included. So, what's your problem? ;-) Gert Link to comment Share on other sites More sharing options...

snettleship Posted June 3, 2009 Share Posted June 3, 2009 When I bought my Seven, it already had a aluminium seat with the cut out for the crotch straps. Link to comment Share on other sites More sharing options...
TheDingo8MyBaby Posted June 3, 2009 Share Posted June 3, 2009 (edited) Hank, My racing seats have an oval hole approximately 1"x3" right infront of the crotch or about the middle of each seat. FYI: This is from the SCCA rule book on Lap Belt Mounting. J.4: LAP BELT MOUNTING J.4.1: The lap belts shall be mounted rearward of the pelvis, between two lines drawn at 60-degrees, and 80-degrees, below the horizontal (see Figure 1). J.4.2: The lap belts shall pass through the seat, without interference, to the attachment points, pulling in plane with the mounting hardware without any visible twisting or edge loading on adjusters or mounting brackets. Mounting points must be as close to the side of the seat and must not rub on any seat brackets, rough, or sharp edges. J.4.3: Lap belt mouting points must be integrated with the frame of the car or to specific welded mounting tabs on the roll cage. If mounting points are located on seat brackets, they must be certified by the bracket manufacturers specifically for such use. Mounting points created in the floor or transmission tunnel must be reinforced with backing plates of sufficient size to spread the load. J.4.4: Lap belts with bolt on connections must allow bracket to pivot either by use of a machined sleeve or by backing the lock nut off just enough so that bracket can pivot. This is critical to prevent loading of one edge. Eye bolts must be aligned properly so that the snap-on connector is not twisted or loaded at an angle that might load one edge of the webbing while the harness is being used. J.4.5: If bolt-in or snap-on mounts are used in conjunction with a 3-bar adjuster the complete wrap must be completed as detailed in Figure 9 and described in J.8 below Edited June 3, 2009 by TheDingo8MyBaby Link to comment Share on other sites More sharing options...
Hank Posted June 3, 2009 Author Share Posted June 3, 2009 For those chosen few that may have viewed the "de-gloved" rally driver with the 6-pt harness accident photos can we attribute his injuries to loose crotch straps? I don't want to make the same mistake. I was told, "The harness should be tight, almost to the point of being uncomfortable, to prevent excessive movement." I won't post the link here, but Google is out there if anybody is interested. Link to comment Share on other sites More sharing options...
TheDingo8MyBaby Posted June 4, 2009 Share Posted June 4, 2009 Oops, I blew it. This is the section I meant to post. G.5: ANTI-SUBMARINE LEG STRAP MOUNTING G.5.1: The double leg straps of the six-point system may be attached to the floor - to a purpose built element of the cage - or to purpose built mounting points in the seat as provided by an approved seat manufacturer. G.5.2: A separate attachment point connection must be provided for each leg strap. G.5.3: Attachment points may use bolts, eye-bolts with snap-on connectors, or wrap mounts to roll cage, seat, or chassis points designed for the sub strap loads. G.5.4: Bolts and eye-bolts through the floor must be reinforced with backing plates provided by the harness manufacturer or large washers on the underside to spread loads. G.5.5: Wrap mounts to specific bars as part of the cage are allowed using only wrap mount hardware provided by the harness manufacturer following the manufacturers defined wrapping instructions. G.5.6: Formula belt and Hybrid belt anti-sub leg straps may share the lap belt mounting point in rearward mounting installations providing there is a direct unencumbered routing as outlined in the belt descriptions. http://www.scca.com/documents/Pro%20Racing/09-prr-appendix.pdf See appendix G. for figures and just about anything you want to know. I have heard of guys getting castrated by 5 points, but it was due to the belt being too far forward and not nearly tight enough. You definitely want them tight as possible - this holds true for all belts. The sub straps are meant to keep the lap belt from pulling upwards, so the less slop, the better the chances of you not submarining. Link to comment Share on other sites More sharing options...
