Abstract: A trunnion door hinge having a first hinge part, a second hinge part and a cam mechanism. The cam mechanism has a first cam part, which is nonpivotable relative to the first hinge part, a second cam part, which is nonpivotable relative to the second hinge part, and a first spring element which presses the first cam part and the second cam part towards one another. The cam mechanism further has a third cam part in-between the first cam part and the second cam part. The third cam part at one end interlocks with the first cam part, and at the other end with the second cam part. During the hinging, the third cam part is helically pivotable relative to the first and the second cam part in a first and a second pivot range, respectively.
