Abstract

The injection relates to a projection system (1) comprising at least two projection surfaces (2) which are respectively provided with a front side (2) and a rear side (16), respectively forming a contact area (18) with one of the side edges thereof. Edge areas (26) of the projection areas (2) are connected to each other in such a way, forming a tensed section (27) whereby the front sides (16) of the projection surfaces (2) are disposed on top of each other and the contact area (18) is formed by fold lines from the projection surfaces (2) folded thereabout. The edge areas (26) of the projection surfaces (2) are continuously connected to each other along the entire length of the contact area (18) and the tensed section (27) is fixed to a rigid holding element (28) extending in an approximate parallel position with respect to the contact area (18).
