Abstract
Abstract In the present system the hinge halves for an automobile door are welded to the pillar and door for economy and to speed up assembly work. This, however, eliminates the usual form of adjustability previously available where the door hinges were fastened by screws to the body and door, and, with oversized holes or slots in the pillar or door, the hinges could be adjusted in and out and/or fore and aft to correctly fit and align the door to the body. The new eccentric bushings herein disclosed permit welding of the hinge halves in normal position, and then adjusting the door by turning the eccentric bushings in the companion upper and lower hinges, so that the proper fore and aft and/or in and out adjustments can be achieved, whereupon the bushings are easily locked in place by lock or jam nuts. Also, where there is a torsion-bar holdopen, the proper relationship between the torsion-bar and detent rollers is maintainable because the adapter plate on which the detent rollers are carried is pivotally connected with the pintle to shift as the bushing is adjusted so as to maintain the proper relationship of the rollers with the torsion-bar regardless of the bushing adjustment.
