ABSTRACT:
There is disclosed a friction hinge assembly that can be inexpensively produced having a shaft and, in the simplest embodiment, one sheet metal part. In the preferred embodiment, the friction band and the bracket are one piece. In order to achieve the necessary alignment between the axis of the friction band and the axis of the shaft, the configuration of the mounting hole for the shaft is elongated only along one axis. This provides clearance for necessary manufacturing tolerances without introducing additional backlash. In another embodiment, proper alignment is assured by slotted mounting holes for mounting the friction bands to the bracket.
