Abstract:
An assembly comprising:a first part; a second part hinged to the first part about a geometric axis lying in a closure plane; and a sheet adhesively bonded onto at least a portion of a surface of each of the first and second parts, wherein said sheet comprises at least one connecting strip which, when the assembly is in a closed position, intersects the closure plane without passing through the geometric axis, said connecting strip being configured to pass through an intermediate position at which the strip intersects the geometric axis and experiences maximum tension, and also being configured to elastically bring said first and second parts to an open position when said strip is on one side of said intermediate point and to elastically bring said first and second parts to an at least partially closed position when said strip is on another side of said intermediate point; wherein said sheet is a film adhesively bonded to an outer surface of one of said first and second parts.
