Protective device with a flexible sheet-like structure movable between a compactly stored position and at least one two-dimensionally extended functional position and which is provided, on an end region thereof with a dimensionally stable extension profile which, at opposite ends, has retaining profile sections mounted so as to be displaceable telescopically to a limited extent in the extension profile and acted upon outwardly in the longitudinal direction of the extension profile by a spring arrangement. Each retaining profile section is assigned a second spring arrangement which acts on the retaining profile section in the opposite direction to the first spring arrangement. The retaining profile section, in an unloaded non-operational position, is held on the extension profile in a central position, from which the retaining profile section can be shifted inward or outward in opposite longitudinal directions relative to the extension profile. |
