Abstract
An internal frame backpack (10) includes a pack (12) having an anterior side (14) that contacts a user's back, and left and right shoulder straps (10, 18) attached at an upper end to an upper portion (20) of the pack and at a lower end to left and right lower portions (44, 46) of the pack. The pack includes an internal frame formed from an elastomeric pad (24) integrated into the anterior side of the pack, and resilient left and right rods (26, 28) mounted within the pack and secured to the elastomeric pad. The resilient rods act as coil springs which support loads in the pack with a degree of flexibility that varies in response to the magnitude of the load.
