Retaining system for a movable component

To be able to transmit higher forces when retaining movable components on board an aircraft, a retaining system includes a support structure with a first retaining area and a second retaining area having a movable locking element, and a movable component with a locking receptacle forming a locking device with the locking element, and a retaining device. The movable component is movably attached to the first retaining area with the retaining device, and the movable component can be locked on the second retaining area with the locking device. The at least one movable locking element can be moved between an open setting (SOFF) and a locked setting (SVER), wherein the at least one movable locking element engages with the locking receptacle in the locked setting, so that the movable component is temporarily immovably retained, and allows the movable component to move in the open setting.
