Abstract
A window with an emergency exit function for a helicopter is described that comprises: a frame shaped as a framework that can be coupled to a door of said helicopter provided with an opening; and a transparent element designed to engage the opening and held in position by the frame; the frame comprises a first side arranged abutting against the transparent element when a first force below a threshold value is exerted on the latter in a direction transversal to a first plane of a main portion of the transparent element, and which can be elastically moved away from the transparent element when the first force exerted on the latter exceeds the threshold value; and a second side having greater flexural rigidity than the first side in a second plane transversal to first plane and arranged abutting against the transparent element even when the force is greater than said threshold value.
