Abstract
The safety bumper includes: (a) a bumper basic body (4) having a forward surface; (b) a bumper bar (5); (c) a mounting member (11); (d) a cross-bar (10) of the vehicle, (e) at least one of a deployable energy-absorbing element (9; 32, 33, 39, 41; 52, 60) positioned above the mounting member (11) and a deployable energy-absorbing element (17, 20; 38, 46; 64) positioned below mounting member (11); and (f) an impact sensor (6) located in bumper bar (5). The bumper bar (5) is connected to bumper basic body (4) and extends through to the forward surface of bumper basic body (4), bumper bar (5) is also connected to mounting member (11), and mounting member (11) is located behind bumper basic body (4) and bumper bar (5). The mounting member (11) is connected to cross-bar (10), which is located behind mounting member (11). The deployable energy-absorbing elements are controlled by impact sensor (6), and upon actuation thereby are deployed and form (either singly or together) a substantially continuous contour and a substantially common front together with the forward surface of bumper basic body (4).
