Abstract
The invention is relative to a window frame, in particular a window for a helicopter intended to fix the window onto a support. This frame includes cutting out means driven by pulling on at least a part of the window perimeter in order to divide into two at least a section of the frame and thus detach the window from the support.
Claims4
A window frame, in particular for a helicopter window, intended to fix the window onto a support, the frame including:
- a joint comprising a central layer from which extends an external edge and an internal adge, the external edge being intended to be fixed onto the support and the internal edge being intended to immobilise the window;
- and
- cutting out means of the frame which are carried by the central layer and which are driven by pulling on at least a part of the perimeter of the window in order to divide into two at least a section of the frame and thus detach the window from the support,
- characterised by the fact that the central layer is made in an elastomeric material harder than that of the internal and external edges.
