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

The invention relates to a backpack (10) having a stowage space (18), which on its side facing the back of a user of the backpack is delimited by a back part (20). The backpack (10) includes a net element (12) and a frame arrangement (22), which for tensioning the net element (12) is designed in such a way that an intermediate space (24) is formed between the back part (20) and the net element (12) when the net element (12) is tensioned. The backpack (10) has two shoulder straps (14, 16) for carrying the backpack (10) on the user's back. The shoulder straps (14, 16) have end areas (42, 44) that cross the intermediate space (24) and are fastened to the back part (20).

A backpack includes a pack body, two length-adjustable shoulder straps extended from the pack body for allowing the wearer to wear the pack body at the wearer's back, and a suspension arrangement which includes a resilient unit provided between the pack body and the shoulder straps for absorbing a bounding force of the pack body. Therefore, the resilient unit allows a relative movement of the pack body with respect to each of the shoulder straps but minimizes the relative movement of the pack body by absorbing the bounding force of the pack body. The resilient unit is also arranged for evenly distributing a loading force of the pack body to each of the shoulder straps, such that the resilient unit absorbs the bounding force of the pack body at different directions so as to balance the uneven loading force at the pack body.

Disclosed packsack damping module and packsack, comprises a housing, a first movable member, a second movable member and an elastic element, the housing is internally provided with a mounting cavity; the first movable member and the second movable member are both provided in the mounting cavity; the first movable member is connected with one end of the elastic element, the other end of the elastic element is connected with the second movable member; or the elastic element is provided with the first elastic member and the second elastic member, one end of the first elastic member is connected with the first movable member, the other end of the first elastic member is connected with the housing, one end of the second elastic member is connected with the first movable member, the other end of the second elastic member is connected with the housing. The disclosure improves the damping effect.

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 support system has a frame, which is equipped with shoulder straps and preferably also a waist belt and which preferably inherently rigid so hat the loads that occur during use, the frame only flexes by inevitable amounts in the millimeter range by which any rigid body flexes when subjected to a load. A bike mount is fastened to the frame. The bike mount is embodied so that the bike, almost exclusively by its frame or frame components such as the rear fork can be fastened directly to the frame, i.e. without luggage or a pack compartment being situated between the bike and the frame in the points at which the bike rests directly against the frame. When properly fastened, the bike is thus affixed to the frame so that it cannot move.

The invention discloses a two-way adjustable shock-absorbing backpack, comprising a backpack main body and back pads arranged on one side of the backpack main body, wherein the back pads are provided two, and the two are symmetrically arranged on the backpack main body, a back pad pocket with a top opening is formed between the back pad and the backpack main body, a support fabric bag is sewn into the back pad pocket, and a support rod is inserted into the inside of the support fabric bag, one side of the backpack main body above the support fabric bag is provided with a fixed fabric belt, in the invention, by adjusting the length of the secondary braces on the upper adjustment button, the shock-absorption adjustment of the top of the backpack is realized, by adjusting the lower adjustment button, the shock-absorbing stroke adjustment of the elastic band is realized.

A portable backpack for the storage and transport of a collapsible quad chair, in which the insertion or removal of the collapsible quad chair is enabled by maintaining the shape of the opening through placement of the flap away from the opening to prevent deformation of the opening.

A Putrello lift assist work belt used for manual conveyance that includes a contoured weight bearing ledge that when structurally coupled with the back support belt and shoulder straps form a Putrello lift assist work belt system able to transfer substantial weight of the load being carried by manual conveyance to the hips and legs thus relieving stress and strain on the users back and arms. The elements and attributes of the Putrello lift assist work belt combine to form a manual conveyance lifting system that provides excellent rigidity and resistance to leverage force that results from having a heavy object extended and positioned in front of one's body thus preventing injury to the back, shoulders, and arms.

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.
