Abstract: One embodiment of the present invention relates to a user based carrying system capable of independent transportation of a load including a hip-based user attachment system. The carrying system includes an enclosure member having an internal region encased by an internal surface. A user attachment system releasably secures the carrying system to the user for independent transportation without requiring muscular engagement. The user attachment system includes a hip attachment system with a dorsal articulation member and a strap member. The dorsal articulation member includes a front and rear member three-dimensionally moveably coupled to one another. The rear member is coupled to the enclosure member and the front member is coupled to the strap member. The three-dimensional moveable coupling between the front and rear members includes three restricted degrees of freedom configured to efficiently absorb corresponding user hip movements and directly support other user hip movements.

Abstract: The present invention relates to carrying apparatus manufacturing processes. One embodiment of the present invention relates to a method for coupling materials of dissimilar stiffness on a carrying apparatus. The method includes adhering a cover fabric member to a base fabric member of different stiffness using applied sandwich pressure and high frequency transmission. The high frequency transmission may include translating the fabric members so as to sequentially straddle a high frequency wheel along a perimeter of the cover fabric member. An adhesive agent is disposed between the cover fabric member and the base fabric member. The adhesion between the fabric members is configured to exceed a peel test tolerance of ten pounds. In addition, optional acts of applying high and low temperatures may be included to pre-tack the cover fabric member to the base fabric member.
