The invention relates among other things to a cover assembly (10) with a first cover part (13) and a second cover part (14), where each cover part (13, 14) is movable relative to a base about a separate pivot axis between a closed position and an open position and is biased by a spring (16a, 16b) into the open position, where one leg (18) of the spring (16a, 16b) is supported on the base and one leg (17) loads the cover part (13, 14), and can be held in the closed position by a latch that is adjustable between a latching position and a release position, where the spring tension is adjustable by an adjuster (20).
The special feature consists in that the adjuster (20) comprises a support (21a, 21b) for a leg (18) of the spring (16a, 16b), which part is supported movably and has at least one locking formation that can be brought detachably into engagement in different relative positions with counterlocking formation (27) fixed on the base, where the support (21a, 21b) has support formation on which the one leg (18) of the spring (16a, 16b) is supportable.
