  • Patent number: 5263665
    Abstract: A mounting bracket for holding a heat insulating mat in an aircraft cabin has a lower and an upper section configured to conform to a trough-shaped flange of a stringer secured to the fuselage. A holding pin forms part of the lower section and can be connected to the insulating mat. The two sections are onto the stringer (2) as a clip. For this purpose the lower section (4) fits with a trough (10) around the stringer (2) and the upper section (5) formed with a snap-in locking device including an expander pin (9) is arranged with a barrel portion in the trough of the stringer. The upper section (5) has a plate (14) tangentially merging into the barrel portion and extending outside the stringer (2) for the snap-in action.
