Title: Bullet-proof or splinter-proof screen
Inventor: GALET ADRIEN
IPC: B32B7/022
Filed: 1986-11-24
Abstract: This screen is of the type constituted by a complex comprising a first thick and hard layer of a methacrylic resin of the type known by the trade name "plexiglass", located on the external surface of the screen and a second, thin and softer layer of polycarbonate, constituting its internal surface, these two layers being separated by a thin air gap. According to the invention, the two layers mentioned above are completed, in front of them, by two other layers, namely a first layer which is constituted by resin of the "plexiglass" type but of flexible nature and which is in contact with the usual hard layer of "plexiglass" resin, and a second layer which, becoming the external surface of the screen, is constituted by a thin sheet of resin of the "plexiglass" type, the presence and combination of these two additional layers having the effect of increasing cohesion and limiting the splintering of the hard layer of resin of the "plexiglass" type which constitutes the essential element of resistance to the impact of bullets.
