Abstract
A retractable shoulder strap for portable objects, such as bags, purses, briefcases or carry-on luggage, comprises a shoulder pad, an elongated strip of pliant material, a plurality of holes positioned at substantially uniform intervals along the length of the elongated strip, and retractors located inside the shoulder pad. Extendible guide wires passing through the plurality of holes connect the ends of the elongated strip to the retractors, which are spring-biased to automatically retract the guide wires and stow the elongated strip inside internal storage spaces in the shoulder pad, thereby eliminating slack in the strap when no tension is applied to the ends of the elongated strip. When tension is applied to the ends of the elongated strip, the portions of the elongated strip stowed in the internal storage spaces of the shoulder pad are automatically extracted, thereby increasing the length of the strap to facilitate normal over-the-shoulder use.
