<p>The invention concerns a vehicle bumper (1) equipped with shock-absorbing means, and comprising a rigid support (3) linked to the vehicle and whereon is fixed a shell (2) for receiving the impact, the shock-absorbing means including at least two pyrotechnic actuators activated by a control system (11) connected to at least an impact and/or deceleration sensor (12a, 12b, 12c). Said bumper is characterised in that each pyrotechnic actuator (9) comprises at least two gas-generating powder tablets (10a, 10b, 10c) capable of being primed individually by the control system (11) so as to supply to the actuator at least two efforts of different intensity levels.</p> |
