Abstract:
A cover device for at least partially closing off a cavity includes at least one cover element for closing off the opening of the cavity, and a support structure in the form of an elongate body for supporting and positioning the cover element in or close to the cavity. The cover element is in the form of a pneumatic mattress equipped with return elements for urging it back into a most compact configuration in which it is rolled up about a free one of its sides and forms a spirally wound roll, the free side being formed by the side of the mattress that is opposite from the connecting side of the mattress via which side the mattress is connected to the support structure. This device includes at least one support arm for supporting the mattress while going from its rolled-up most compact configuration to its rolled-out least compact configuration.
