<p>The aid (10) has a base body (14) for accommodating a use section, and a cap (12) overlapping a head section. The base body and the cap form a pivot bearing (26) at front surfaces (16, 18) facing each other. The cap is fixedly supported on the base body, and the pivot bearing exhibits a rotational axis passing through a predetermined breaking point. A convex curved section is formed at the base body. The cap and the base body are formed from elastic and smooth material. The use- and head sections exhibit inner- and outer contours complying with each other.</p> |
