Abstract
A knapsack has a bag, a strap assembly for attaching the bag to the shoulders of a user, a belt assembly for attaching the bag around the waist of a user and a fastening system for fastening the strap assembly and/or the belt assembly to the back of the bag. The fastening system has a first piece secured to the strap assembly and/or the belt assembly and a second piece secured to the back of the back. The first and second pieces co-operate with each other to enable the first and second pieces to be fastened together and pivot mutually about an axis perpendicular to the back of the bag. The fastening system has at least one elastomer element secured to one of the pieces and the other piece has a portion that causes the elastomer element to be deformed during pivoting, thereby opposing the pivotal movement.
