Connecting module for an orthodontic treatment means

A module for resiliently connecting a face bow to a head harness in an orthodontic treatment device comprising:

• a fastening band releasably attachable at one end to the face bow and having a slide bar section at another end, the slide bar section having a longitudinally extending opening therein;
• a bow releasably attachable to the head harness;
• a housing resiliently latchable to the bow and having a hole into which the slide bar section projects;
• and
• pressure means for resiliently holding the slide bar section in the housing such that the slide bar section may be partially pulled out of the housing, the pressure means being disposed within the opening in the slide bar section and being supported when longitudinal force is applied between the housing and the fastening band by an axial end of the opening in the slide bar section and by support means in the housing.

A connecting module for an orthodontic treatment device having a face bow and head harness comprising:

• a fastening element releasably attachable at one end to the face bow and having a sliding section at another end;
• a housing element having a hole into which the sliding section projects;
• means for releasably attaching the head harness to the housing element;
• and
• compression spring means for resiliently holding the sliding section in the housing element such that the sliding section may be partially pulled out of the housing element by an application of force to the housing element or fastening element, the interior of the compression spring means being at least partially vacant in the axial direction thereof.

A connecting module for an orthodontic treatment device having a face bow and head harness comprising:

• a fastening element releasably attachable to the face bow and having engaging means for engaging a compression spring;
• a housing having a hole into which the engaging means projects and having support means for supporting a compression spring;
• means for releasably attaching the head harness to the housing;
• and
• a compression spring which resiliently holds the fastening element to the housing against an application of force to the fastening element or housing, the compression spring being engaged at one end by the engaging means and supported at the other end by the support means during the application of such force;
• wherein the engaging means extends along the exterior of the compression spring.
