Abstract

A wristband for mounting a wearable device having a back case around a user's wrist to place the back case in contact with the user's skin. The wristband has a flexible layer with adjusting elements for adjusting the wristband to the user's wrist, coupling elements for coupling the flexible layer to the back case, and a buckle coupled to an end of the flexible layer. The buckle has a frame and a pivoting prong coupled to the frame for selective engagement with the adjusting elements. A tightening mechanism is arranged in the frame for obtaining a predefined adjustment of the wristband band around the user's wrist to thereby increase the contact of the back case with the user's skin. The tightening mechanism includes a ratchet gear having locking teeth arranged at a periphery of the ratchet gear over a predetermined angular range, a pivoting strut configured for selective engagement with the locking teeth to place the tightening mechanism in a locked state, and a mechanism for pivoting the pivoting strut to disengage from the locking teeth to place the tightening mechanism in an unlocked state.
