die Trennkante --20-- anschliessende, kreisbogenförmige Laschen --3-- mit den Verriegelungselementen. Die Einschubschächte --4-- haben im Bereich der Öffnung-Ib-auf der Innenseite Vertiefungen, welche so geformt sind, dass die federnden Zungen der Laschen --3-- bei nach innen gedrückten Tasten --16-- den dafür nötigen Spielraum erhalten.
Am Kinnbügel --2-- ist an der Unterkante --2a-- die Halskrause --5-- angesetzt, welche eine Fortsetzung der an der Unterkante --la-- der Helmschale --1-- angesetzten Halskrause - darstellt.
Im dargestellten Ausführungsbeispiel wurde der gedachte Mittelpunkt 0 der Kreisbögen so gewählt, dass die Kreisbögen der beiden Laschen --3-- ein nach vorne-oben Wegschwenken des Kinnbügels --2-- ermöglichen.
Der kreisbogenförmige Steg --4a-- im Einschubschacht --4-- dient dazu, die Laschen - in herausgeschwenkter Position zu stützen und ein verkantungsfreies Wiedereinführen der Kinnbügellaschen zu ermöglichen.

hinteren Verriegelungselemente --11-- und den hinteren Abschluss der Laschen --3--.
Bezugnehmend auf Fig. l bis 4 sind jene Verriegelungselemente --10, 11-- dargestellt, die in den Laschen --3-- durch die dreiseitigen Trennschlitze --15-- federnde Zungen bilden, an deren jeweiliger Aussenseite zylindrische Erhebungen --16-- die Tasten bilden. Diese Tasten --16-- sind in Einschubrichtung abfallend abgeschrägt.
Schliesslich können die Verriegelungselemente auf der Sturzhelmaussenseite besonders gekennzeichnet sein und das Öffnen bzw. Entfernen des Kinnbügels kann z. B. durch Aufkleber graphisch beschrieben sein.
PATENTANSPRÜCHE :
1. Sturzhelm, dessen Helmschale am rückwärtigen Teil der Halsöffnung eine Halskrause aufweist, welche vorzugsweise am Hals enganliegend ausgebildet ist, mit einem von der Helmschale lösbaren Kinnbügel, der nach vorne-oben schwenkbar ist, wodurch die Halsöffnung beim Aufsetzen bzw.
Abnehmen des Sturzhelmes vergrössert werden kann, dadurch gekennzeichnet, dass kreisbogenförmige Laschen (3) mit Kanten, Nuten oder Schlitzen (3a) in Kreisbogenrichtung an den beiden der Helmschale (1) zugewendeten Enden des Kinnbügels (2) ausgebildet sind und dass in der Helmschale (1) zu den Laschen (3) passgenaue, kreisbogenförmige Einschubschächte (4) vorgesehen sind, wobei die Laschen (3) Verriegelungselemente (10, 11) aufweisen und in der Helmschale (1) im Bereich der Einschubschächte (4) Öffnungen (lb) angeordnet sind, in welche die Verriegelungselemente (10, 11) einrasten und von aussen betätigt werden können und dass die Halskrause (5, 6) am Kinnbügel (2) fortgesetzt ist.

the separating edge --20-- connecting, circular arc-shaped tabs --3-- with the locking elements. The slots --4-- have recesses in the area of the opening-Ib-on the inside, which are shaped so that the resilient tongues of the tabs --3-- when the buttons are pressed in --16-- have the necessary scope receive.
On the chin guard --2--, the neck brace --5-- is attached to the lower edge --2a--, which represents a continuation of the neck brace attached to the lower edge --la-- of the helmet shell --1--.
In the exemplary embodiment shown, the imaginary center point 0 of the arcs was selected such that the arcs of the two tabs --3-- allow the chin strap --2-- to be swiveled forward and upward.
The arc-shaped web --4a-- in the insertion slot --4-- serves to support the tabs - in the swiveled-out position and to enable the chin strap tabs to be reinserted without tilting.

rear locking elements --11-- and the rear end of the tabs --3--.
With reference to FIGS. 1 to 4, those locking elements --10, 11-- are shown which form resilient tongues in the tabs --3-- through the three-sided separating slots --15--, on the respective outer side of which cylindrical elevations --16 - Form the buttons. These keys --16-- are sloping in the direction of insertion.
Finally, the locking elements on the outside of the helmet can be specially marked and the opening or removal of the chin guard can e.g. B. be described graphically by stickers.
