So, looking to replace ‘95 FZJ80’s first and second row seat belts w/ all hardware including retractors. I research everything to death (no pun intended)—and there are more options out there than one might think. Before finalizing, I thought I’d run it past the Brain Trust and see what the general consensus is on this.
Note: Stock belts lock when retractors are off-level, which can be annoying when off-road and you need to twist around or stick your head out the window, or both. Options for new belt retractors are:
These options are available for front AND second rows. (Haven’t asked about 3rd.)
1 (Stock)—lock up when off-level, and on sudden deceleration when pulled out fast (anyone have the G figure on this?).
2 (Dual Sensitive)—lock up when ~15 degrees off-level, or when being pulled out at 0.7G [G FIGURE CORRECTED]
3 (Web Sensitive Only)—does not lock up at all by going off-level, regardless of angle; locks up when being pulled at 0.3G [G FIGURE CORRECTED]
A (Tri-Lock)—CAN BE ADDED TO 2 OR 3 ABOVE (aftermarket): by pulling the belt all the way out and then releasing it, you cause it to lock up snugly, keeping you in position. When you don't do this, the belt still acts as specced above.
Options 2, 3, and A meet and exceed the Federal Motor Vehicle Safety Standards, section 209 (FMVSS-209, the section involving seat belts). Not sure about 1, only because I’m not sure offhand how old that standard is.
For me, it’s a DD 95% on-road miles / 5% off and (for the most part) no radically dangerous terrain I can see in time to avoid. At first glance, I’m thinking 2A or 3A. My only concern would be--in a slow-motion rollover or roll-onto-side (particularly if not caused by impact and at very low speed) with 3A—would that pull the belt out at 3Gs? (There’s a reason for off-level lockup…) Have this Q into the mfr now and they say it keeps you in place; will post update when I get details on how...
UPDATE: Both 2 and 3 above will lock-up on rollover, even if it's a slo-mo rollover.
What's your usage and preference?
