Zu der Erfindung führten die folgenden Überlegungen. Ein besonders guter Tragekomfort bei gleichzeitiger Aufrechterhaltung einer guten Belüftbarkeit des Raumes zwischen dem durch eine Rahmenstruktur konkav aufgespannten Netzteil und der Rucksackrückenwand kann dadurch erreicht werden, dass die das Netzteil spannende Rahmenstruktur zweigeteilt wird. Durch diese Zweiteilung wird eine weitgehende Entkoppelung der Bewegungen des Netzteiles einerseits sowie der Bewegungen des Rucksackes andererseits ermöglicht. Gleichzeitig werden jedoch die Spannung der Rucksackrückenwand sowie die Spannung des Netzteiles aufrechterhalten. Es wird auch sichergestellt, dass die von der Last des Rucksackes ausgeübte Kraft beidseits der Längsachse des Rucksackes direkt jeweils in den Bereich eines Beckenknochens des Rucksackträgers eingeleitet wird. Dadurch ergibt sich ein verbesserter Tragekomfort.The following considerations led to the invention. A particularly good wearing comfort while maintaining a good Ventilierbarkeit the space between the concave by a frame structure mounted power supply and the backpack back wall can be achieved by dividing the power supply exciting frame structure is divided into two. Due to this division into two parts, an extensive decoupling of the movements of the power supply is achieved on the one hand and the movements of the backpack on the other hand allows. At the same time, however, the tension of the backpack back wall and the voltage of the power supply are maintained. It is also ensured that the force exerted by the load of the backpack on both sides of the longitudinal axis of the backpack is introduced directly into the area of a pelvic bone of the backpack wearer. This results in an improved comfort.
