An embodiment of the present disclosure is an article that includes a lumbar support member, internal frame assembly, and sternum strap for improving stability during use.

A vacuum cleaner system includes a vacuum cleaner and a harness assembly removably connectable to the vacuum cleaner. The harness assembly includes an upper support assembly and a lower support assembly. The upper support assembly includes an upper back pad, at least one shoulder strap emanating from the upper back pad, an upper pocket in which an upper mounting plate of the vacuum cleaner is received, and an upper flap selectively connectable to the upper pocket to close the upper pocket and retain the upper mounting plate within the upper pocket. The lower support assembly includes a lower back pad, a waist belt emanating from the lower back pad, a lower pocket in which a lower mounting plate of the vacuum cleaner is received, and a lower flap selectively connectable to the lower pocket to close the lower pocket and retain the lower mounting plate within the lower pocket.

A backpack is provided. The backpack includes, a first shoulder strap having an attachment end and a distal end, and a second shoulder strap having an attachment end and a distal end. The backpack may include a shoulder strap tongue connected with the attachment end of the first shoulder strap and the attachment end of the second shoulder strap. The backpack may include a waist support system including a waist belt including a first section and a second section. The first section includes a first attachment end and a first distal end and the second section includes a second attachment end and a second distal end. A first connection portion is disposed on the first section at the first attachment end, and a second connection portion is disposed on the second section at the second attachment end. The first connection portion is releasably attached to the second connec tion portion.

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 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 backpack including a pocket demarcated by a dorsal wall opposite the back of the user when the backpack is carried, and a frame partially fixed to the dorsal wall, the frame including a structural portion for shaping the dorsal wall. The frame includes an extension, connected to the structural portion, extending towards the back of the user from the structural portion, the extension being designed and arranged so as to define a support section located in the area of the lumbar zone of the user when the backpack is carried. The structural portion of the frame forms a camber such that a median portion of the structural portion is further away from the back of the user than its upper and lower ends.

A backpack with multiple connected airbags includes a backpack body, a first airbag unit, and at least an air inlet. The backpack body has a set of straps. The first airbag unit includes a plurality of first airbags and is connected to the rear side of the backpack body. A groove and an air channel are formed between each two adjacent first airbags. The air channels allow the air in the first airbags to flow between the first airbags. The first airbags are so arranged that each first airbag in the peripheral region of the first airbag unit occupies a larger area on the rear side of the backpack body than any first airbag in the central region. The air inlet is in communication with at least one first airbag. The backpack can lie compliantly against the user's back to provide enhanced comfort and stability while protecting the user's spine.

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.

A backpack has a pack body with front, side, and back walls. A transverse belt slot is disposed across a lower portion of the back wall. First and second waist belt portions each have distal and proximal ends. A plurality of spaced apart connection mechanisms are arranged within the transverse belt slot. The proximal end of the first waist belt portion is releasably and pivotally connectable with any one of the plurality of spaced apart connection mechanisms arranged within the transverse belt slot. The proximal end of the second waist belt portion is releasably and pivotally connectable with any other of the plurality of spaced apart connection mechanisms arranged within the transverse belt slot. The distal end of the first waist belt portion and the distal end of the second waist belt portion being releasably connectable together.

Disclosed herein is a container having a base defining a first end, a second end, a front wall, a rear wall, and an inner base layer that defines an interior volume of the container. The container further includes a shoulder strap coupled to the rear wall and a moveable lid coupled to the base at the first end. The moveable lid includes a cover and a plug. The plug protrudes from the cover and forms an interference fit with the inner base layer to seal the interior volume when the moveable lid is in a closed position.
