Head-mountable device band with a latch movable by a tab

A band for a head-mountable device, the band comprising:

• a strap that defines an opening;
• a latch body located in the opening;
• a bar extending through the latch body;
• a tab that wraps around the bar, wherein displacement of the tab by a first distance causes actuation of the latch body by a second distance that is different from the first distance, wherein:
• the opening comprises a first surface opening and a second surface opening larger than the first surface opening, and
• the opening defines a tapered surface based on the first surface opening and the second surface opening;
• and
• a ring located between the first surface opening and the latch body.

A head-mountable device, comprising:

• a frame that carries a display;
• a pin extending from the frame, the pin comprising a cavity;
• and
• a band coupled with the frame, the band comprising:
• a strap that defines an opening;
• a latch body configured to enter the cavity;
• a pulley;
• a tab that wraps around the pulley, wherein in response to an applied force to the tab, the pulley facilitates movement of the latch body out of the cavity;
• and
• a ring that extends into the opening and engages the pin.
