Motor cyclists crash helmet - has cap shaped shell chin strap in form of two armed lever with press button in recess

摘要

The helmet (2) has a cap-shaped shell (3) enclosing the cyclist's head, and a chin strap (5) gripping under the lower jaw. The chin strap is movably attached to the shell so that it flaps up, and, when lowered, is locked to the shell. A press button (6) in a recess (5e) on the front of the chin strap unlocks it and is in the form of a two armed lever moving on a horizontal axle. The lower arm (6c) enables the chin part (5) to move upwards and the upper lever arm (6d) acts as the press button. A compression spring (11) is positioned between the chin part and the upper lever arm. At least one mushroom shaped locking bolt (8) has a wire snap (9) fitting into it. ADVANTAGE - The chin part of the crash helmet is more easily released and swivelled up onto the helmet by having a two-armed lever which is both pressed and pulled.
