Claims22
A bumper bar (2) for a motor vehicle, comprising front (4) and rear (6) walls and an intermediate web (14) extending from the front wall to the rear wall so as to form with the latter an “H”-shaped section, wherein the web has an undulating shape in cross section and the bar (2) has at least two zones (8, 10) in which, in cross section, the web (14) has an average thickness less than an average thicknesses of the front (4) and rear (6) walls and said zones are each closer to respective ends of the bar than to a middle of the bar.
A bumper bar (2) for a motor vehicle, comprising front (4) and rear (6) walls and an intermediate web (14) extending from the front wall to the rear wall so as to form with the latter an “H”-shaped section, wherein the web has an undulating shape in cross section and the bar (2) has at least one zone (8, 10) in which, in cross section, the web (14) has an average thickness between 0.25 and 0.75 times the average thicknesses of the front (4) and rear (6) walls.
A bumper bar (2) for a motor vehicle, comprising front (4) and rear (6) walls and an intermediate web (14) extending from the front wall to the rear wall so as to form with the latter an “H”-shaped section, wherein the web has an undulating shape in cross section, and which, in two zones (10) each closer to respective ends of the bar than to a middle of the bar, comprises at least one rib (16) perpendicular to the front (4) and rear (6) walls and to the web (14).
A bumper bar (2) for a motor vehicle, comprising front (4) and rear (6) walls and an intermediate web (14) extending from the front wall to the rear wall so as to form with the latter an “H”-shaped section, wherein the web has an undulating shape in cross section, and which, in two zones (10) each closer to respective ends of the bar than to a middle of the bar, comprises at least one cell (21) extending between the front (4) and rear (6) walls.
A bumper bar (2) for a motor vehicle, comprising front (4) and rear (6) walls and an intermediate web (14) extending from the front wall to the rear wall so as to form with the latter an “H”-shaped section, wherein the web has an undulating shape in cross section, and the bar (2) has at least one zone (8, 10) in which, in cross section, the web (14) has an average thickness less than average thicknesses of the front (4) and rear (6) walls, and the at least one zone (10) extends at right angles to a location (18) for fixing the bar (2) to longitudinal members (12).
A bumper bar (2) for a motor vehicle, comprising front (4) and rear (6) walls and an intermediate web (14) extending from the front wall to the rear wall so as to form with the latter an “H”-shaped section, wherein the web has an undulating shape in cross section, and at least one internal wall (24, 28) parallel to the front (4) and rear (6) walls.
A bumper bar (2) for a motor vehicle, comprising front (4) and rear (6) walls and an intermediate web (14) extending from the front wall to the rear wall so as to form with the latter an “H”-shaped section, wherein the web has an undulating shape in cross section, and, in particular in a central zone (8) of the bar, at least one intermediate wall (26) at an angle to the front (4) and rear (6) walls and perpendicular to the web.
