## Abstract

A low profile backpack system is provided which includes a mechanism for allowing free movement of the shoulder straps as the wearer moves, bends, twists from side to side, etc. The inventive mechanism comprises a buckle having a pair of transverse elongated slots. The buckle is fixed to the top of the pack by means of a single vertically oriented strap which passes through the lower of the two slots. A second strap passes through the upper slot and has its ends fixed to an end of each of two shoulder straps adapted to fit over the shoulders of the wearer. A further inventive feature is the provision of a quick release fire shelter on the pack which may be deployed by one hand. The shelter is stored in a rectangularly shaped pouch depending from the bottom of the pack. An open end of the pouch is selectively closed by a flap secured by Velcro fasteners. Pulling a release strap depending from the pouch first disengages the fasteners. Further pulling of the release strap causes the folded safety tent to be ejected from a plastic housing in which it is stored within the pouch.

## Claims

### Claim 1

In a pack system having a backpack and means for mounting said backpack on a wearer, wherein the improvement comprises a pouch adapted for containing a separate structure to be deployed, said pouch being mounted on said backpack and including a discharge opening therein, closure means for selectively closing said opening and release means for opening said closure means and ejecting said separate structure from said discharge opening.

### Claim 2 (depends on 1)

The invention of claim 1 wherein said closure means comprises a flap and further including fastener means on said flap for releasably securing said flap in a closed position over said discharge opening.

### Claim 3 (depends on 1)

The invention of claim 1 wherein said release means comprise a release strap having a pair of opposite ends, said pouch having an interior wall, one end of said release strap being fixed to said wall adjacent to said opening, said release strap passing around said structure so that pulling of the other end of said release strap causes the strap to straighten out and eject said structure from said pouch.

### Claim 4 (depends on 3)

The invention of claim 3 further including a housing within said pouch for containing said structure, said housing having an opening therein for dispensing said structure, and wherein said release strap passes around said structure within said housing.
