Abstract text

A hinge assembly for coupling a spa cover to a spa, said spa cover being movable between a fully closed position and a fully open position. The hinge assembly includes a mounting bracket adapted to be installed near a top of the spa, and adapted to be coupled to a first end of a spring member; and a support arm pivotably coupled to the mounting bracket about an axis of rotation, adapted to be attached on an outside surface of the spa cover, and adapted to be coupled to a second end of the spring member. At least one of the mounting bracket or the support arm has a plurality of openings for selectively coupling the first end or the second end of the spring member, so as to adjust a coupling location between the spring member and the at least one of the mounting bracket or the support arm.
