A protection system to reduce the effect of a vertical acceleration triggered by a landmine on the passengers supported in a cabin (2) of an armoured vehicle is disclosed. For this, a receiving unit consisting of a seat body (7) and a backrest (8) is movably supported by two guides (18, 19) in a carrying frame (6) which is parallel to a sidewall (1) of the cabin of the vehicle and pivotally connected (5, 12) to a sidewall and the roof structure (4) of the cabin, and is coupled to a longitudinally-variable damping device (11) which is fixed at its lower end via a hinge (13) to a lower area (14) of the carrying frame while its upper movable end is connected with a hinge (15) to a bracket (16) carrying the seat (9), so that a sufficient vertical acceleration of the cabin induces both a downward movement and a tilting movement of the receiving unit (together with a passenger (3)) relative to the vehicle.
