Abstract
A reel assembly includes a housing, an axle within the housing, a reel within the housing, a first spring and a second spring. The housing has a fixed connection portion. The fixed connection portion is fixed from rotation relative to the housing. The axle is configured to rotate about an axis of rotation. The reel is configured to rotate about the axis of rotation and the axle. The first spring is coupled between the axle and the fixed connection portion of the housing. The second spring is coupled between the axle and the reel. The second spring has a torque profile associated therewith different from a torque profile of the first spring. Rotation of the reel relative to the housing in a direction tending to tension the second spring transmits rotational movement to the axle through the tensioning of the second spring. Such rotational movement of the axle is applied to the first spring to tension the first spring.
