Abstract
A locking or adjustment device is placed on the of the shell of a helmet for the purpose of attaching, securing, detaching or adjusting the effective length of a chin strap or cheek strap. The locking device may be part of a multi-part or flip-up helmet shell. A manual control device is located on the helmet shell and is accessible from the outside of the shell such that manual pressure on the control surface of the control device from outside the shell disengages a connection with the chin strap. The control device is integrated with the helmet shell in the area of the neck ring, preferably on the side of the neck ring. In a neutral position of the control device, the control surface thereof is continuous with an exterior surface of the helmet shell.
Claims12
A control device for actuating a locking device placed inside a shell of a helmet for changing a locking condition of a chin strap of the helmet, comprising:
- a control part having a surface which is accessible from outside the helmet shell, wherein the control part is integrated with the helmet shell in an area of a neck ring of the helmet shell such that in a neutral position of the control device, the surface of the control part is continuous with an outer surface of the helmet shell, forming at most a minor interruption of the outer surface of the helmet shell;
- and,
- guide means in the neck ring area of the helmet shell for guiding the control part into the helmet shell upon application of a vertical force, wherein said guide means includes a guide part for guiding the control part, the guide part being provided in a cut-out at an edge of the helmet shell, the cut-out being dimensioned to accommodate the control device.
The device according to claim 7, wherein an viewed from lower, interior portions of the helmet, the guide opening has an inward bend and the control part has a corresponding curve, such that when the control device is in the neutral position, an outer side of the control part rests along an outside contour of the helmet shell.
The device according to claim 14, wherein the guide means defines a pair of guide grooves configured to define an activation path of said control part, said activation path providing initially a substantially vertical displacement of the control part and thereafter an oblique guided displacement of the control part.
