there are basically two types of seatbelts. "pull-up", and "pull-down".

The former, which sounds like what you have, are made so the driver is snugged down by pulling up on the webbing, at the floor attachment. My understanding, is that this system is made for the pit crew to belt the driver in, for the race.

the latter is what street cars probably have, where you snug your seat belts by pulling down, by grabbing the loose end of the belt at the buckle. So with this system, you don't have to try to reach down alongside the seats, and try to somehow pull them up.

I have a full five point harness, with "pull-down" lap belts, and "pull-down" Y style shoulder belts. The crotch strap, which i likewise always use, holds the belts down more comfortably, does not have any easy adjustment, it is just fit with the floor mounted hitch point. I have a Deiest on the passenger seat, and a Simpson small buckle for the driver. Both are comfortable, i like the smaller "latch and link" of the Simpson. A full set of Simpsons, with mounting eyelets, and steel back up plates, in Y configuration for the shoulder belts, is about a hundred bucks from them directly.

Seatbelts do wear out from fraying, i am on my third or forth set due to fraying from the knurled adustment slider.

I wear all of it, all the time.
