HEADBAND VARIABLE STIFFNESS

摘要

A method and apparatus are provided for allowing a user to change the stiffness of their headband, thus changing the clamping force of the headset. The section properties of the headband equivalent spring, which is a cantilevered beam, are changed by engaging a secondary spring, which is also a shorter cantilevered beam. The change is achieved by manipulating the effective length of the secondary spring, which can be accomplished with a set of clamps. Thus, the stiffness of the headband can be modified to the desire of the user.

主权项

1. A method for changing a stiffness of a headband, comprising
aligning a primary spring and a secondary spring together, wherein the primary spring and the secondary spring are flexible curved beams, each having a shape of an arc, and wherein the primary spring and the secondary spring are shaped to caress and fit against a human head; joining the primary spring and the secondary spring together with two or more moveable clamps; moving a member of the two or more moveable clamps along the primary spring and the secondary spring such that the member clamps the primary spring and secondary spring together at that particular point and varies the stiffness of the headband relative to the member being located at a different point along the primary spring and secondary spring; and increasing the stiffness of the headband by increasing a spacing between the two or more moveable clamps positioned along the primary spring and the secondary spring.
