US 6,473,937 B1 · Motor vehicle door hinge having an integrated braking and holding function

Abstract

The invention relates to a motor vehicle door hinge having an integrated braking and holding function. Said door hinge is comprised of a first hinge half which acts upon a door assembly part, a door, or a door pillar, and of a second hinge halve which acts upon another door assembly part. The door hinge also comprises a hinge pin which pivotally connects both hinge halves to one another. The hinge pin is made of a solid material and is accommodated in at least one hinge eye of a hinge half with a running fit and is accommodated in at least one hinge eye of the other half with a close fit. A braking and holding device which is integrated in the hinge comprises at least one spring-loaded braking and holding body. Said braking and holding body is aligned in a radial manner relative to the hinge pin and interacts with a circumferential profile of the hinge pin, said profile extending over a part of the circumference thereof. The aim of the invention is to obtain an increasing braking of the opening movement of the doors over a predetermined permitted opening angle of the doors, and inversely to obtain a progressively easier closing movement of the doors. To this end, the circumferential profile of the hinge pin which extends over a part of the circumference thereof forms a braking ramp comprising a contour which continuously increases in the door opening direction. In addition, the braking and holding body which interacts with said braking ramp is configured as a friction body.

A motor vehicle door hinge with integrated braking and holding function, comprising:

a first hinge half fastenable to one of a door and a door pillar,
a second hinge half fastenable to the other of said door and said door pillar,
a hinge pin pivotably connecting said first hinge half with said second hinge half, said hinge pin being a solid material and being arranged with a running fit in at least one hinge lug of one of said first hinge half and said second hinge half and with a firm fit in at least one other hinge lug of the other of said first hinge half and said second hinge half, and
a braking and holding arrangement integrated into the hinge, comprising a circumferential hinge-pin profiling extending over part of the circumference of said hinge pin, at least one braking and holding body displaceable radially with respect to said-hinge pin, and a spring urging an end face of said braking and holding body into frictional contact with said hinge pin profiling,
wherein said hinge-pin profiling defines an ascending profile such that the holding force of the hinge increases in an opening direction of the hinge and decreases in a closing direction of the hinge.
