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.

Abstract: A door assembly, in particular for a helicopter, has a post; a door fitted to the post by a first and second hinge arranged on an outer wall of the post, so as to rotate about a hinge axis to open and close a door opening; and an emergency release device having a release handle, and a stem which extends through the post along a release axis substantially perpendicular to the hinge axis, rotates axially, in response to operation of the release handle, from a first to a second angular position to detach the door from the post, and is fixed at one axial end to the first hinge; the release handle being connected to the stem to rotate together with the stem about its release axis.
