Klippan seat belts ??

Hi,
For you guys who had see everything : I found a pair of sport seats with these unusual seat belts. This is just a plain belt that you catch under the lever and close it after ?! Any info on these ?

I just found that Klippan is a swedish company. What this factory or dealer installed you think ? 70's ? (they were on a 70E Euro delivered car)

Thanks !!

My RoW MY 71 originally came equipped with Klippan belts but they have an "airplane style" receiver system.

Someone told me that a 69 Mercedes come with them also. He had aslo some concern about safety ; Any comments or feedback on how "safe" they are ??:confused:

+1. Belt fabric this old is very likely to be worthless.

Klippan belts came on BMW 1600 and early 2002 models

I had belts like these in my Italian sold 73 S, not sure when they got mounted but I think my car came with inertia. Was "good" with "klapping" style between they seats is that they work with brand new rols from Porsche, just take away the "male". I have this set up in my 73 E.
