3 point seat belt's for my 7 seater

Whilst my landy is laid up with a few problems I've been thinking about the next major thing the wife is going to want... propa seat belts in the middle and rear two seats for the sprogs. Anyone know if there is a kit out there to convert the lap belts into real seat belts?

if you meant the side facing seats in the rear then three point belts are dangerous in them and I believe not legal.. they don't add anything to safety either unless you're going sideways at the time...

for the middle seat in the main bench I would have thought there are kits out there but no idea where you would attach it as they have to be fixed to something solid rather than the discovery boot .. which probably isn't...
