ABSTRACT:
A hinge comprises a first and a second bracket that are at least partially spaced apart. A viscoelastic member is disposed between and secured to the brackets to permit relative rotation between them about an axis that passes through both brackets and the viscoelastic member. At least one of the brackets includes a stop engagable with the other bracket to prevent rotation of the first bracket relative to the second bracket about the axis of rotation in one direction beyond a predetermined relative orientation of the two brackets. Relative rotation between the brackets when the stop is engaging the other bracket occurs about a second rotational axis spaced from the first axis and passing through a point of contact between the stop and the other bracket.
