Abstract
The present invention provides for a backpack having a pack bag and a modular pack frame. The modular pack frame includes a generally flexible frame sheet that is fixed to a rigid support bar at the center of the frame that is contoured to mimic the shape of a user's backbone. The frame sheet is similarly curved and adapts to fit the remainder of the user's back. A pad overlies the sheet and extends throughout the pack frame. Reinforcement members are positioned in the pack frame and pack bag to prevent distortion of the pack frame and to concentrate the load of the pack toward the lumbar region and comfortably distribute the remainder of the load to the user's shoulders, hips, and other portions of the back.
