Abstract
A suspension belt end connector has first and second wrapping elements that are arranged in a housing. The housing may have a back wall, side walls and an open side opposite to the back wall. The side walls taper and form with the back wall and a yoke a suspension unit to accommodate a suspension bolt. The end connector supports a poly V belt which serves as a suspension element. The belt is laid around the first wrapping element in a first loop, around the second wrapping element in a second loop, and again around the first wrapping element in a third loop that runs opposite to the first loop. The end of the belt is then held fast by means of a clamp or wedging device. Ribs of the first and third loops mutually engage, as a result of which the coefficient of friction in the engaged section of the belt is increased.
