  • Patent number: 6619590
    Abstract: A connecting device for joining a windshield with a fuselage side frame of a viewing port of an aircraft, especially a cockpit frame of a helicopter. The connecting device includes a fastening element which is fixed into position on a section of a peripheral region of the windshield through a bore hole and into a congruent bore hole of the fuselage side frame and in a fastening part with a spring device. A peripheral slit filled with a sealant is arranged in a peripheral region between the fuselage side frame and windshield. The fastening part includes a retaining nut and a spring device which can be moved and guided within a seating element and connected with the fuselage side frame. The spring device is arranged between the retaining nut and the frame.
