ABSTRACT:
An arm bearing for an awning has at least one support block, at least one bearing block arranged to swivel about a first rotation axle into a drop-out position, and an arm rotatable about a second rotation axle transversely to said first rotation axle. A threaded coupling rod couples the support block and the bearing block for tilting movement of the bearing block. An adjustable nut is coupled to the threaded coupling rod for limiting the tilting movement of the bearing block within variable limits. At least one lock is coupled to the arm and is transversely displaceable to the threaded coupling rod for locking engagement with the adjusting nut. The adjusting nut has at least one recess or projection arranged approximately radially with respect to the threaded coupling rod for locking engagement with the lock. An eccentric cam is rigidly connected to the arm for positively controlling displacement of the lock.
