  • Publication number: 20240081489
    Abstract: A band includes a latch body that is movable by pulling a tab. The latch body extends through an opening of the band and secures with a pin located on a head-mountable device. The band can detach from the head-mountable device by pulling the tab, which actuates the latch body and removes the latch body from the pin. A spring (or springs) can bias the latch body toward the opening, causing the latch body to enter the pin. An applied force to the tab can overcome the biasing force provided by the spring(s), and move the latch body away from, and out of, the pin.
