Interior fittings of a vehicle such as a folding caravan

Interior fittings of a folding vehicle structure comprising a lower body having a floor and four lower side panels, four side upper panels mounted to pivot on the lower panels, the fittings comprising a first piece of furniture having a first base rigidly connected to a first said lower side panel and a first upper member mounted to pivot on the first base about a first longitudinal pivot, said first upper member being able to move between a horizontal retracted position and a vertical position for use where it is connected to a first said upper side panel, a second piece of furniture having a second base connected rigidly to a second said lower side panel and a second movable upper member, the distance between the floor and the first pivot corresponding at least substantially to the overall depth of the first upper member in order that in the retracted position of the first upper member a front wall of the first upper member rests on the floor, wherein the height of the second base is at least equal to the sum of the depth of the first upper member and of the height of the second upper member, and wherein the second upper member is connected to the second base and to the second said upper side panel by first kinematic connecting means such that the movement of the second upper side panel causes the accompanying movement of the second upper member between an upper position for use in which it rests on the second base when the second upper side panel is vertical and a retracted lower position, when the second upper side panel is horizontal, in which it rests at least partly on a rear wall of the first upper member in the retracted position, the first and second pieces of furniture being located at least partly in facing relationship, the first kinematic connecting means also having the function of keeping the second upper member in a constant relative position.
