Patent ID: 8197165

Claim:
A fastening device for fastening a movable element in a cabin of an aircraft in the event of turbulence during flight to a structure of the aircraft, the fastening device comprising: a first support element; and a first belt retractor having a retractable belt and a first fitting, the first belt being capable of unrolling from the first belt retractor during normal use of the movable element; the first belt retractor being coupled to the first support element such that when the first support element and the first belt retractor couple the movable element to the structure of the aircraft by positively placing, plugging or clamping the first support element on the movable element and fastening the first fitting to the structure of the aircraft by attaching the first fitting to a first portion of the structure of the aircraft and when turbulence exerts an external force, having a force component acting vertically, acts on the aircraft, such that the first support element could be moved upward in relation to the structure of the aircraft, then the first belt retractor prevents unrolling of the belt by more than a predefinable range wherein the first support element has a u-shaped profile attachable to the movable element.
