Frames for mounting rear lap/sash (retractable) seat belts

[Tom]

Hi, I need to install rear lap/sash (shoulder) seatbelts in my 2CV and have engaged an engineer to design a steel frame that will do the job without being too intrusive while also complying with Australian Design Rules.  To avoid reinventing the wheel, the engineer has asked if I could get some photos (or drawings) of how others have installed them here in Australia. Can anyone help please?  I’ve found photos of two installations on the Aussie Frogs site but nothing else as yet. Apparently there are some other designs in use, some simple and easier to install and live with than others.  I’ll happily post photos of whatever I end up with if it’s different again.  Cheers and thanks, Tom

Hi Tom
Here are some pics from my installation, passed in QLD. They should be self-explanatory, otherwise just ask.
It was done by the previous owner, so I don’t have any paperwork or anything else though.

Thanks for the photos John.  It’s a really nice, simple mod.  In SA (and some other southern states) we can’t use that one… to be ADR compliant we need a purpose built mounting frame that’s engineer-certified and also incorporates child seat anchor points. Because of rear-end crash safety concerns, my preference is a design that doesn’t extend or mount behind the rear axle like some I’ve heard about.  Hopefully there’s something like that out there and we’ll get to see some photos.   🙂

Hi,

Are you still looking for ideas?  I’m making one up at the moment in consultation with a Victorian VASS inspector. It does extend beyond the rear axle but is tied to the chassis with 3mm steel plates.

Progress to date attached.  The inertia reel is from a scrapyard, and mounted in the boot well for a tidy finish.  Top plate is yet to be welded to the body.

 

For the child seat anchor points I’m making a stronger cross piece across the body where the boot hinge is, welding and/or high strength rivet to the body.  No photos yet it’s still in design. 😉

Thanks for the photos Tim.  Looks great.  Since posting on here I’ve heard about an ADR-compliant kit made in Australia for local 2CV owners.  I’ve ordered one and it should be here soon.  Have seen one installed and it’s a clean and simple solution. Essentially 2 curved plates sit on top of the inside mudguards like saddles.  They are bolted in place (6 bolts each side) using anchor plates mounted under the wheel arch.  Attached to these saddle plates is a horizontal bar that runs just behind top of the back seat.  The bar has 2 child seat anchor points and provision to bolt on standard Repco lap/sash retractor belts.  Will post photos when it’s installed.

Here are photos of the ADR-compliant mounting bar I eventually installed for the rear lap-sash seat belts.  The bar comes as a ready made kit available from 2CV parts supplier ‘Mr Citroen’ (Rolf Breyer).  The bar is fixed on the rear mudguards as shown. Not shown is the matching curved bracket fitted externally under the mudguard.   It’s a nice, simple solution.

The belts bolt onto the mounts nearest the windows.  The two other brackets are mandatory child seat mounting points with internal reinforcement, and yes, they’re in use!
