A strap length adjusting apparatus includes first and second stationary plates and a middle plate disposed between them. The middle plate can rotate relative to the first and second stationary plates. A biasing device is linked to first and second coupling members between the middle plate and the first plate. The biasing device can either couple the middle plate to the first plate or decouple the middle plate from the first plate. When the first and middle plates are decoupled from each other, the middle plate can rotate with respect to the first plate, and a strap partially wound about a rod that extends from the middle plate, can wind about the rod either clockwise or counterclockwise so as to continuously change a length of the strap that extends away from the rod.
