A padding device (10a; 10b; 10c; 10d; 10e), for a carrying belt system (100) for a respirator (1000), has a closed pad core shell (20) and a pad core (30) configured in the pad core shell. The padding device is formed by injection molding a hollow profiled section, inserting of a pad core material into the hollow profiled section for forming the pad core in the hollow profiled section, and closing the hollow profiled section (21) for creating the closed pad core shell (20). The padding device (10a; 10b; 10c; 10d; 10e) has a closed pad core shell (20) and a pad core (30) arranged in the pad core shell. The pad core shell is seamless as an injection-molded component in at least some sections. A carrying belt system and a respirator with the carrying belt system are provided with the belt system having the padding device.

Backpacks having lumbar pads as at least one component that has been manufactured using 3D printing or other additive anufacturing 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.

A backpack-type assembly may include: a body; and a base member. The body may include a cooling fan. The base member may include: a back plate attached to the body; and a harness attached to the back plate and configured to be worn on a user. The harness may include: a cooling port; and at least one shoulder belt configured to be worn on a shoulder of the user. The cooling fan may be configured to circulate cooling air into or out of the base member through the cooling port of the harness.

A process manufactures a padding device (10a; 10b; 10c; 10d; 10e), for a carrying belt system (100) for a respirator (1000), having a closed pad core shell (20) and a pad core (30) configured in the pad core shell. The process includes injection molding a hollow profiled section, inserting of a pad core material into the hollow profiled section for forming the pad core in the hollow profiled section, and closing the hollow profiled section (21) for creating the closed pad core shell (20). The padding device (10a; 10b; 10c; 10d; 10e) has a closed pad core shell (20) and a pad core (30) arranged in the pad core shell. The pad core shell is seamless as an injection-molded component in at least some sections. A carrying belt system as well as a respirator with the carrying belt system are provided with the belt system having the padding device.

A method of reducing forward head posture is disclosed herein. Such a method may include: providing a backpack that includes a sternal pad included on one or more shoulder straps, a sacral pad, and one or more dorsal pads; positioning the sternal pad included on the one or more shoulder straps on a wearer's sternum and upper anterior ribs; positioning the sacral pad on the wearer's thoracolumbar junction, such that the sacral pad spans at least a portion of a bottom of the backpack; and positioning the one or more dorsal pads on the wearer's spine and shoulder, where the sternal pad, the sacral pad, and one of the one or more dorsal pads when positioned on the wearer are arranged in a triangular configuration when viewed from a side perspective of the wearer.

According to a first aspect, load-bearing systems can have one or more serpentine tensioners. According to another aspect, load-bearing systems can have one or more repositionable load-bearing members. Load-bearing systems having serpentine tensioners and load-bearing systems having repositionable load-bearing members are not mutually exclusive of each other. Accordingly, some disclosed load-bearing systems have a serpentine tensioner in combination with a repositionable load-bearing member. To facilitate disclosure of such principles, wearable packs incorporating one or more aspects of innovative load-bearing systems are described.

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).

The backpack with inflatable cushions comprises a backpack, inflatable shoulder pads, and an inflatable lumbar support. The backpack may be adapted to be worn on a user's back, supported by a pair of shoulder straps, and may be operable to carry items within the backpack. Non-limiting examples of the items that may be carried within the backpack comprise school supplies, camping gear, sports equipment, and a change of clothing. The inflatable shoulder pads may be adapted to distribute the weight of the pair of shoulder straps over a larger area of a user's shoulders when the inflatable shoulder pads are inflated with air. The inflatable lumbar support may be adapted to fill the space between a user's lower back and the bottom of the backpack when inflated, thus promoting good posture and reducing back pain.

A topless storage bag, including a main body to store at least one item therein, a removable divider removably connected to an interior of the main body to separate the interior into a first section and a second section, a waist strap assembly disposed on a bottom portion of the main body to connect around a waist of a user, a shoulder strap assembly disposed at a first end on at least a portion of a top portion of the main body and at a second end on at least a portion of the waist strap assembly to suspend the main body from shoulders of the user, and a chest strap assembly disposed on at least a portion of the shoulder strap assembly to connect around a chest of the user.
