Multifunctional Outdoor Backpack with Built-In Rest Stool and Emergency Stretcher

The problem

Hiking groups and field teams carry standard backpacks that hold supplies but provide no structural support for resting. When someone needs to sit, they rely on uneven ground or separate folding stools that add weight. If a team member is injured and cannot walk, the group must improvise a stretcher from branches or clothing, which takes time and may not be stable. Moving an injured person over flat terrain by hand is exhausting, and carrying separate stretchers, stools and carts defeats the purpose of traveling light.

The solution

This backpack integrates the parts needed for resting and emergency transport directly into its structure.

1. A height-adjustable support frame sits inside the backpack main body (1). It passes through an opening (3) so the frame can tighten the fabric from the inside, forming a rigid rest stool.
2. Four three-stage telescopic rods (13) are stored in dedicated compartments. They splice together end-to-end to form two stretcher lift bars (14).
3. The upper support plate (5) and lower support plate (6) detach from the support frame. Together with the two lift bars, they assemble into an emergency stretcher.
4. Detachable universal wheels (25) clip onto mounting holes on the lower plate or hard mounts on the bag bottom, while one telescopic rod inserts into a handle hole on the upper plate to create a wheeled cart.

Who it is for

• Outdoor gear brands expanding their hiking and expedition pack lines with built-in safety functions.
• Wholesalers supplying scout troops and youth camps where groups need shared rest and emergency equipment without extra bulk.
• Adventure tour operators guiding multi-day hikes who want a standardized pack that doubles as rescue equipment.
• Amazon sellers targeting the preparedness niche looking for a differentiated travel bag with clear functional selling points.

How it works

The main parts

Operating steps

1. Rest stool mode - Pull the support frame (4) through the opening (3). Adjust the height. The crossed support rods (7) lock via fastening bolts (24) sliding in strip holes (23), tightening the backpack main body (1) into a seat.
2. Stretcher mode - Remove the upper support plate (5) and lower support plate (6) from the frame. Take out the four three-stage telescopic rods (13) from the elastic fixing rings (29) in the compartments (28). Splice them into two stretcher lift bars (14). Attach the protective liner (21) by threading the fastening straps (22) through the fastening holes (19) on the lift bars.
3. Cart mode - On flat ground, install the detachable universal wheels (25) into the universal wheel mounting holes (32) on the lower plate (6) or onto the hard mounts (27) at the bag corners. Insert one telescopic rod (13) into the handle mounting hole (26) on the upper plate (5) and pull.

Applications

Group hiking expeditions

When a hiking team stops for a break, members deploy the internal frame to create seats instead of sitting on wet or rocky ground. The backpack remains compact during movement because all parts store flat inside the compartments.

Wilderness injury response

If a hiker twists an ankle far from a trailhead, the group extracts the telescopic rods and support plates to build a stretcher. The protective liner and straps secure the patient, allowing the team to carry them out without improvising unstable poles.

Flat-terrain evacuation

Once the group reaches a dirt road or flat path, they attach the universal wheels to the lower plate and insert the handle rod. This converts the stretcher into a wheeled cart, reducing the physical strain of carrying the injured person over distance.

Scout and youth camp outings

Camp leaders distribute these packs to squads so each unit carries its own rest and rescue capability. During training exercises, scouts practice assembling the stretcher and cart modes, learning emergency procedures with standardized equipment.

Field research and survey work

Survey teams working in remote areas use the stool mode while recording data at stations. The remaining cargo space holds instruments and daily necessities alongside the structural components.

Where it is less suitable

• Ultralight solo backpacking - The frame, plates, rods and wheels add weight that solo hikers counting every ounce will avoid.
• Urban commuting - The specialized compartments and rigid parts make it bulkier than a standard daypack for city use.
• Technical rock climbing - Climbers need streamlined harness-compatible packs without protruding frames or hard plates.
