A lattice support structure has lattice bars pivotally connected to one another and extending in the longitudinal direction of the lattice support structure as well as lattice bars connecting them, with the connecting lattice bars being connected directly or indirectly to the lattice bars extending in the longitudinal direction such that the spacing of the lattice bars extending in the longitudinal direction of the lattice support structure can be decreased on the inward folding of the lattice support structure and increased on the folding apart of the lattice support structure.
