Abstract (en)
The door has a door (2) rotating with respect to a chassis (1) around an axis (3), and including hinges (8-10) integrated to it. End bearings are integrated to the chassis. One damping cushion is inserted along the axis between each bearing and hinge, and is made of elastomer or metallic foam. The cushion is deformable in plastic or elastic manner. Intermediary bearings stop translation of the cushion along the axis. An independent claim is also included for application of a protected trap door for the protection of an operator of an armored vehicle against impact caused by the movements in site or in the field of turret or weapon.
