HEADBAND VARIABLE STIFFNESS
First Claim
1. A method for changing a stiffness of a headband, comprisingaligning 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.

Abstract
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.

5. A headband that enables a user to change a stiffness that results in changing a clamping force to a head of the user, comprising:
-
a first flexible material and a second flexible material that are elongated and shaped in an arc to fit over the head of the user; the first flexible material having a length longer than the second flexible material; the first flexible material and the second flexible material aligned together, and clamped together with two or more moveable clamps, wherein the two or more moveable clamps can slide along the first flexible material and the second flexible material when aligned together; and the two or more moveable clamps operable to change the stiffness of the headband when located in different positions along the first flexible material and the second flexible material. - View Dependent Claims (6, 7, 8, 9)

10. A method for changing a clamping force to a head of a user, comprising:
-
elongating a first flexible material and a second flexible material; shaping the first flexible material and the second flexible material into an arc to fit over the head of the user; creating the first flexible material with a length longer than the second flexible material; aligning the first flexible material and the second flexible material together; clamping the first flexible material and the second flexible material together with two or more moveable clamps; and moving the two or more moveable clamps to different positions along the first flexible material and the second flexible material to change a stiffness of the headband. - View Dependent Claims (11, 12, 13, 14, 15)
