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.

A backpack for use alone or in conjunction with a hiking or book backpack where the backpack includes a plurality of storage compartments, a main storage compartment, a first side storage compartment and a second side storage compartment. A top opening of the main compartment is accessed via the opening and closing mechanism to allow the user access to the interior volume of the main storage compartment when in a horizontal orientation and a top opening of the first compartment is accessed via the opening and closing mechanism of the first compartment, which is positioned at the top of the first compartment when the flexible backpack system is positioned in the vertical position and from the side when in the horizontal position.

Articles are described herein. An example article may comprise a first surface comprising a first lattice. The example article may comprise a second surface at least partially spaced from the first surface. The second surface may comprise a second lattice. The first surface and the second surface may define a cavity therebetween. The first surface and the second surface may be formed as a unitary body. A configuration of the first interconnected struts, the second interconnect struts, and the third struts may be tunable to control a stiffness and ventilation of the example article.

Disclosed are shoulder belt sliding-down preventing method, and a related preventing tool, shoulder belt, and bag. The belt-shaped neck hanging element is connected to a belt at positions separated from each other via connecting members. A loop-shaped space is thereby formed between the belt body and the neck-hanging element. The head passes through this space, and the neck hanging element contacts the side of the neck. In operation, the connecting member is removed and held with one hand, the belt body is hung on the shoulder, the connecting member is passed around the back of the neck, the neck hanging element is hung around the neck, and the connecting member is engaged again with the belt body. The belt body of the shoulder bag can hang on the shoulder and the neck hanging element can be wound around the neck, thereby preventing the belt body from sliding down the shoulder.

A harness assembly for an electrical appliance includes an upper support assembly and a lower support assembly. The upper support assembly includes an upper back pad and at least one shoulder strap emanating from the upper back pad. The upper back pad includes an upper pocket that receives an upper mounting plate of the electrical appliance therein, 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 and a waist belt emanating from the lower back pad. The lower back pad includes a lower pocket that receives a lower mounting plate of the electrical appliance therein, 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-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.
