Abstract
A temple end piece for a temple of a spectacle frame has a unit stable in a form composed of an essentially horizontal first segment and a second segment curving downward to the rear in the shape of an arc. Connected to this unit is a third segment formed by a soft, flexible band, the upper end of which is attached to the first segment and the lower end of which is permanently connected to the lower end of the second segment. This band extends in the uncharged state of the temple end piece curved essentially in the shape of an arc, in fact, in a manner similar to the second segment. In its longitudinal direction the band is neither stretchable nor compressible. By virtue of its high flexiblity the band fit the shape of the auricle and/or head of the spectacle wearer when the spectacles are worn in place, so that a large contact area with lower pressures will adjust itself, and any and all pressure points are prevented in this contact area. Owing to the constancy of length of the band the flexible configuration will not detract from the stability of support for the temple of the spectacles.
