Hello ...
I am look for a middle seat belt ... the one which you need for the middle chair in the back. A secondhand will do but they seem to be pretty expensive (45 euro).
Can I also use a middle belt of other renault types? Which ones are compatible? This would give me more search options .... I have a espace type III
Whilst you should have the lap belt for the centre seat, and if it is missing, you really need another; are you aware that if you are NOT using either one of the third row seats, their belts are made long enough for use on the centre seat? This also provides the centre seat with a full lap and diagonal belt rather than just a lap belt. Clever little addition by Matra.
As for other model compatibility - I doubt any would fit as Matra used two buckles on the seat and a belt with tongues on either end, whilst most models have one end fixed, and one tongue on the other end.
I'll take a look as I might still have a belt in my stock. (can't remember if I sold it or not) If I have, I'll let you know.
