ABSTRACT:
An end stop is disclosed for limiting the maximum displacement of a flexible member so as to minimize stress on this member and thus provide an extended surface life. The flexible member is rigidly supported at at least two spaced-apart points such that the flexible member can flex in the region between these points. The end stop includes a support member for clamping the flexible member at the two supporting points and a wall surface arranged in opposed, facing relationship to the flexible member in the region between the two points. The curvature of the wall surface is defined by first and second curves that form a continuous curvature and have first and second derivatives of the local angle .phi. of the tangent to the curve with respect to the distances along the curve which are zero.
