i'm beginning to think that for some weird reason the 89 nissan 240sx is the only car in existance with that kind of shoulder harness and nobody in the universe knows how to work it exactly.

 

My guess is since the car was introduced in 89 to the US but was in production in Japan b4 then, to pass US regulations they stuck the first seatbelt they could in from their current lineup...

 

just use the lapbelt

 

I'm sure if you had a child you'd want them to be as safe as possible too, at least I would hope

 

i could care less about my safety it's my little girl i'm worried about.

 

AHAHA!!!!! I'm all mighty!!! I, and only I have the only owners manual in the world that remains fro mthe 240sx!!!!!!
I have the knolege!!!! and I think I can help you, I'll scan the pages and try to put them on here, maybe this is so rare and noone knows that I'll become a sticky

"sticky: The rear lapbelt, shoulder belt thread"!!!
jajaja

 

LMFAO! Actually I have the owners manual also... I find it very funny how we can swap motors, take a car that doesn't run and make it run, make cars that go so fast, yet we can't figure out how our seat belts work. LOL!

 

i have one for the 91 fatsback, are they the same for 89s?

edit: here are mys cans , beat ya to the punch hehe.

 

nope that is how to install a car seat... in teh 89 there is a lapbelt and a shoulder belt that are seperate and no one can figure out how they hook together. this pic shows a standard seatbelt that is one peice.... good try though.

 

my '91 rear was different, had the retractable belt in the back...this one just confuses me

 

yeah i'm with s13 240 on that. i'm thinking the next time i'm in nc i'll take the seat belts out of my 91 and be done with it.

 

I have the same belts
Take the lap belt. look where the belt loops through the buckle( between the belt and buckle), there should be a round slot. the round peg on the shoulder belt slides into this slot.

 

hello captain obvious. that was so easy it makes my head hurt thinking about how long it took me to figure it out. thank you for opening my eyes. if you need anything within reason hit me up. i feel a lot better now that my daughters car seat is held in there like a rock.

 

no problem,
still if there is anyone who can't figure it out.
you take the lap belt buckle

between the belt and buckle there are some grooves

take the shoulder belt buckle

slide it into the center hole

then slide it over into the smaller groove


hopefully this helps the rest

 

congrats!!!.....the great mystery has been solved! i never took the time to actually look at the buckle. i guess when you don't really sit in the back seat, you just don't care that much.
