Abstract: The invention relates to a rucksack (1) with a horizontally and vertically rear-ventilated air conditioning zone (6). It is composed of a shoulder strap carrying system (2), a rear wall (3) with a stiffening frame (4), and a mesh (5) stretched across the rear wall and/or across the stiffening frame for creating the rear-ventilated air conditioning zone (6) between the rear wall (3) and the back of a rucksack wearer. By virtue of the stretched mesh (5), the rear wall (3) is kept away from the back of the wearer both in the hip region and in the shoulder region and allows both a horizontal and a vertical exchange of air. In a variable embodiment of the rucksack (1), the rucksack (1) can optionally be adapted to the body of the wearer by attaching the shoulder straps (2) in the shoulder-side region in a horizontally and vertically adjustable manner to a baseplate (15) attached to the mesh (5).

Abstract: The invention relates to a backpack having shoulder straps and an adjustment plate for attaching the shoulder straps so as to be adjustable in the horizontal and vertical directions; the adjusting plate is fitted on a network, which network is spaced apart from a rear wall of the backpack by a rear-ventilated climate zone.

Abstract: The invention relates to a diffuser attachment (1) for a portable lamp, in particular helmet lamp (9), comprising a transparent or translucent housing (2) whose first end (3) is closed by a cap (8) and has a reflector element (7) in the form of a diffuser mirror and whose second end forms a base region (6) which is adapted to the outer shape of the lamp (9) in order to permit reversible fixing of the diffuser attachment to the lamp, the reflector element (7) of the light source (13) being opposite and the distance between reflector element (7) and light source (13) being at least 1 cm, in particular 1 to 20 cm and typically 5 to 10 cm when the diffuser attachment is fixed. For removable mounting, the diffuser attachment can be connected to the lamp via a fast-action coupling mechanism, in particular via a snap, clamp, screw or bayonet coupling.
