Inside a socket (6) runs a spring (7), one end of which is connected to a bow front piece (3), while its other end is connected to one end of an intermediary part (8). This part also runs in the socket, and has its other end connected to a bow rear piece (4). - The intermediary part can have a cross section which slidably connects to the inner section of the socket so that the bow rear piece is guided in its longitudinal direction. |
