Multi-tensile assembly for a band used with electronic devices
12024820 · 2024-07-02 · ·

An assembly with multiple structures, each having different tensile strengths, is integrated into a band used with various electronic devices. The assembly may include a low-tensile structure designed to elongate under an initial tension, thus allowing the band to stretch and lengthen. However, additional tension applied to the band is transferred to other structures of the assembly. Further, when the applied tension causes the structure with the highest tensile strength in the assembly to straighten (or substantially straighten), the high-tensile strength structure prevents the band from further elongation. The low-tensile strength structure allows the band to conform to a user, while the high-tensile strength structure protects the low-tensile strength structure from damage or unwanted deformation.
