Embodiments herein discloses a wearable device for holding a backpack. The device comprising a base member and a flexible support member. The base member configured to receive the backpack comprises one or more arms. The arms are engaged to a flexible support member via engagement members. The device is fastened around waist of a user via a fastening mechanism. The base member of the device rest on a posterior of a pelvic region, and the arms are configured to hold an iliac crest of the pelvic region, when the user wears the device. The device is configured to distribute a part of a vertical weight of the backpack into a horizontal thrust on the pelvic region.

A convective air pad with weight balancing and massage buffering effect, which includes a pad body (1), convective air chamber (2) integrally and uniformly arranged on a surface side of the pad body (1), wherein the convective air chamber (2) is filled with gas, wherein the convective air chamber (2) includes airbag members (21), a convective channel (22) connected between each two adjacently positioned airbag members (21), and a ventilation gap (23) provided between each two adjacently positioned airbag members (21). Through the convective air chamber (2) on the pad body (1), the load-bearing portion is in direct contact with the convective air chamber (2) to provide a very strong weight reducing and pressure buffering effect, thus effectively reduce the stress from the load to the load-bearing portions. The convective air chamber (2) is formed by a number of interconnecting airbag members (21) so that the pressure can be dispersed effectively by gas movement through the convective channels (22), therefore the load is translated into massage effect on the load-bearing parts through the interconnecting airbag members (21) and hence the fatigue and pain in the load-bearing parts is greatly reduced. Moreover, since ventilation gap is formed between the airbag members (21), the contact area between the load-bearing parts is effectively reduced while a superior ventilation effect is provided, hence the heat is dissipated effectively and timely and the comfort level is increased.

A wearable safety system comprising a harness comprising a back protection panel, two shoulder straps and a hip belt. The harness is configured to be worn on the torso of a wearer. The system further comprises at least one inflator; and at least one airbag. The wearable safety system is configured to generate an activation signal upon detection of an accident. The at least one airbag is configured to be inflated upon the generation of the activation signal and to be deployed to form at least one inflated body having an extension across at least one of the head and shoulders of the wearer, the thorax area of the wearer and the hips of the wearer. Further, a bag arrangement is provided.

A backpack and frame are disclosed, as are methods of making the frame using composite materials and compression molding. The backpack frame is designed to be at least partially internal and is of unitary construction using a resin-impregnated material, such as resin-impregnated carbon fiber sheets with selective reinforcement by interstitial layers. The frame has a mid-back portion that includes openings for independently positionable shoulder straps and a lower back portion that provides for a rotatable connection to a belt assembly. A pair of curved stay portions is contiguous with the mid-back portion of the frame and curves outwardly as the stay portions extend downwardly. The frame is preferably curved to match the curvature of the human back.

A bag, such as a backpack, includes a back panel having an edge portion, a spacing panel having a fixed edge attached to the back panel and a free edge, an adjustment device, and a lace connecting the adjustment device and the spacing panel. The adjustment device can be configured to retract the lace, thereby translating the spacing panel toward the edge portion of the back panel, thereby increasing a space between the spacing panel and the back panel. The space between the spacing panel and the back panel can be smaller in a first configuration than in a second configuration and the back panel of the bag can be curved in the second configuration.

A massage structure to be mounted onto a back portion of a backpack includes a base and a plurality of protrusions. The plurality of protrusions are distributed in a predetermined discrete manner over the base and arranged to align with at least one specific acupoint on a back of a user. Each of the protrusions protrudes outwards away the back portion from the base with a predetermined height for applying massage onto the back of the user carrying the backpack. The massage structure further includes a pair of extended bases upward extended from a top end of each base to the straps of the backpack respectively, and a plurality of extended protrusions formed on the extended bases and arranged to align with at least one specific shoulder acupoint on a shoulder of the user.

Backpacks having lumbar pads as at least one component that has been manufactured using 3D printing or other additive manufacturing technologies. backpack may include 3D manufactured parts including a lumbar pad, shoulder harness, hip belt, or back panel. The component or lumbar pad may include a lattice structure that allows airflow or provides cushioning. The lattice structure may: have multiple layers, include a network of beams and nodes (e.g., that create cells), or be monolithic. The cells may be polygons (e.g., hexagonal) or cells may line up in multiple layers of lattice structure. Cells that line up may have equal numbers of sides. Other embodiments include systems for providing custom backpacks where consumers enter consumer body dimension(s) and the system fabricates a custom backpack or component using the body dimension or desired load capacity, for example, using 3D printing.

An ultralight backcountry backpack may include at least one shoulder strap connected to a pack body. The pack body may include a back wall configured to interface with a user's back when the backpack is worn, a front wall distal to the back wall, and a perimeter wall connecting the back and front walls. The back, front, and perimeter walls may define an interior storage compartment. The perimeter wall may include an upper region and a basal region. The basal region may comprise a probe zipper, a shovel blade zipper, and a shovel rod zipper. The backpack may include a tool storage apparatus comprising a probe sleeve, a shovel blade sleeve, and a shovel rod sleeve. Each sleeve may be configured to be accessible at the basal region by opening and closing the corresponding zipper.

The present invention relates to a portable garden waste bag (10, 11) comprising two shoulder straps (3).

The present disclosure discloses a carrying rack for carrying an object on the back, comprising shoulder straps and preferably a waist strap, wherein the carrying rack comprises a back plate. Provision is made for that the back plate is formed by a shaped part adapted to the shape of the back in horizontal and vertical directions, wherein the back plate preferably extends from a pelvic region to a shoulder region.
