i HAVE A MAD PROJECT TO INTRIDUCE THE SAME IDEA OF ARCH LIKE THE PARIS CONCEPT.

rED BELT FOR THE FILET OF SECURITY REPLACE THE ENROLLER.

fOR THE ARCH I HAVE SEVERAL IDEAS LIKE THE AUDI TT ARCHS

i THINK THAT I CAN REALISE ONE ARCH FOR ABOUT 50 EUROS. (CHROMIUM FINITION)

Interesting, would be good to see if could be pulled off. That would give you the convertible style roll hoops with the added benefit of a sold roof.

Where would the roll over hoops fixing points be?

by the looks of the drawings they would fit on to the existing headrests, aestetics only maybe??

The arch is made into 2 part: a turntable cut out with laser and one comes to weld an arch whose form remains to be chosen because I do not know really which form choosen. These element will be sent at an industrialist who chromium plates the metal parts, or one can choose a completion with a color carossery. The platine comes to plug in below the support head: the distance between center of the holes correspond to that of the stems of the support head. For safety, the arch is behind the support head - I had thought of adding a blocking system per screw: a ring is welded under each hole of distance between centres and a screw thumb peremt to block the arch onto the stem of the support head. For the net of safety, I had to think of dismounting the existing roller and to replace the bache by a net made up of straps of protection (even matter that that of the safety belts) One would take again the small bar which allows the blocking of the bache.( it is straightforwardly necessary to buy a complete roller which cost approximately 110 euros with the catalogue, rather expensive like element)
