Roof unit and basic structure of a road-bound vehicle
View Patent ↗A process for manufacturing a road-bound, horizontally fitted vehicle body with a roof unit having an outer skin and an inward facing ceiling, or an outer skin and an inward facing ceiling with a ceiling frame, whereby the roof unit is a unit ready for installation, and a basic structure having longitudinal frames, the ceiling and the outer skin along with the basic structure having joining configurations that mate with each other at mutual places for joining. The process includes the steps of introducing the roof unit containing the outer skin with joining configurations, the ceiling or the ceiling and the ceiling frame, in each case with fittings already mounted in place, through an opening between the longitudinal frames, bringing the roof unit into contact with corresponding, matching configuration points of the longitudinal frames by an upward movement and permanently jointing the roof unit there.
1. A process for manufacturing a road bound vehicle body with a roof unit having an outer skin and an inward facing ceiling, or an outer skin and an inward facing ceiling with a ceiling frame, and a basic structure having longitudinal frames, the ceiling and the outer skin along with the basic structure having joining configurations that mate the ceiling and the outer skin to the basic structure at mutual places for joining, the process comprising the steps of:
providing a groove along an entire length of the roof unit and a corresponding bulge along the longitudinal frames as the joining configurations;
introducing the roof unit containing the outer skin with joining configurations, the ceiling or the ceiling and the ceiling frame, in each case with fittings already mounted in place, through an opening between the longitudinal frames, the fittings including at least one fitting from a group of fittings consisting of: fittings for a ceiling cover; interior clodding; cushioning against impact; sun shields; an interior rear view mirror; interior lighting; wiring; operating and display elements; sliding, raising, folding, lamellar elements; and roof hand grips;
bringing the roof unit into contact with corresponding of the joining configurations of the longitudinal frames by an upward movement; and
permanently joining the roof unit there by raising the roof unit to the roof frame of the basic structure until the roof unit touches the roof frame and by further raising the roof unit so that the bulge fits into the groove.
2. A process according to claim 1 , wherein the ceiling has a sandwich structure.
