ABSTRACT:
A pad is fastened angularly movable to pad levers of spectacle frames. The pad has a kidney-shaped pad body, which has a skin contact surface merging, with circumferential radii, in a rear surface which is spaced from the skin contact surface. The pad is cast around an anchoring plate, which has an elongated contour in the longitudinal extension of the pad body and is substantially thinner than the pad body. A finger projects perpendicularly from the anchoring plate and passes through the rear surface of the pad body. In its free end zone, the finger has a cross hole with extends transversely to the longitudinal extension of the pad body. The anchoring plate and the finger are of the same material. The pad body consists of glass-clear silicone rubber having a Shore-D hardness of 10-30 according to DIN 53 305. The anchoring plate consists of a transparent plastic material that is harder than the pad body and is a lattice-work of small rods which enclose open-work.
