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.

Abstract: A head-mounted device may have a head-mounted housing containing rear-facing displays that display images for a user when the head-mounted housing is worn by the user. The head-mounted device housing may have housing structures such as elongated housing members with protruding posts. A headband may be removably coupled to the head-mounted device housing. The headband may have a strap with openings configured to receive the posts. Releasable latches may be provided to allow selective engagement and disengagement between the headband and the housing. The latches may contain movable latch members that are biased using magnetic biasing mechanisms, spring-based biasing mechanisms, or other biasing mechanisms. To release each latch, a tab, button, toggle lever, slider, or other release mechanisms may be actuated by a user. This moves the movable latch member from a closed latch position to an open latch position that releases the headband from the housing.
