US Patent 8950643 Combination backpack and over-the-shoulder bag

The present invention relates to bags, including backpacks and messenger bags.

A combination bag may comprise a bag body having a front panel, a back panel, a bottom panel, and an opening opposite the bottom and a strap, wherein the strap is fixedly attached to the bag body at a first connection point and slideably coupled to the bag body at a second connection point, thereby enabling a wearer to alternate between an over-the-shoulder and a backpack configuration without requiring that the wearer disconnect or reconnect the strap.
