I have a seatbelt on the L/H side which doesn't get in the way, the strap is on the outside of the bench and the buckle bit stays underneath when not in use - my daughter seat is nice and solid on there, and a lap-belt on R/H seat. However baby no.2 is on the way so I need a second 3-point belt for another kiddie seat. At Busfest i'm going to look in every Dormobile I see to see what others have done, the top fixing point is above the fridge-cupboard so i assume the strap will just to be flapping around (and in the way a bit) when not in use?
just found these photos ... Dormobile conversion with three point belts retro-fitted.
and a suggestion of additionally to this solution passing the belt under the wooden frame instead meaning it doesn't flap about over that long storage area lid.
what you think ?
