SECUREMENT FOR AN ELECTRONIC DEVICE

An electronic device can include a band that having a bifurcated rear portion. The bifurcated rear portion can include an upper elongate structure and a lower elongate structure that extend between bifurcation points of the band. In one example, each of the upper and lower elongate structures includes an outer tube, one or more inner tubes at least partially disposed within the outer tubes, and a biasing member, such as an elastic cord, disposed within both the upper and lower elongate portions. The inner tubes can be anchored to another portion of the electronic device such that the outer tubes, which slidably engage respective inner tubes, can be moved or pulled backward from the inner tubes and the display portion to adjust the size of the band. The elastic biasing member disposed within the upper and lower elongate members, including the outer tubes and the inner tubes, is configured to resist the backward movement and provide a tension force against the user's head when the user dons the electronic device.
