Definitions
- the present invention relates to a front bumper arrangement for a high fronted vehicle such as for example a Sport Utility Vehicle (SUV).
- the bumper assembly is designed to provide enhanced safety to a pedestrian in the event of a collision between the vehicle and the pedestrian, and in particular to reduce the bending angle of the legs in an accident between such a vehicle and a pedestrian.
- GB 2 328 654 It is known from GB 2 328 654 to provide a pedestrian protection to a bumper for a saloon vehicle in which the bumper includes a first reinforcement and a bumper stay, and an auxiliary reinforcement and an auxiliary bumper stay which are disposed below the first reinforcement.
- the auxiliary reinforcement aligns with the first mentioned reinforcement.
- the initial deceleration is performed by the upper bumper stay which is deformed.
- the lower, auxiliary bumper stay controls the motion of a pedestrian after the initial state of the collision in such a way that the legs of the pedestrian are allowed to rotate into the upper area of the front of the vehicle and over the top of the bonnet.
- a bumper arrangement for a high fronted vehicle comprising an elongated bumper cover extending horizontally across the front of the vehicle and an elongated grille bar extending across the major part of the front of the vehicle at a level above that of the major part of the bumper cover, wherein the grille bar comprises at its rear side a stiffening member extending substantially across the length of the grille and which is located at a height of between 680 mm to 795 mm from the ground.
- the grille bar comprises a housing to accommodate the stiffening member.
- the grille bar comprises two extending side walls, each side wall including a slot for connecting the stiffening member to the grille.
- the bumper cover is also provided with extending walls arranged in such a way that in assembly position, i.e. when the grille bar is connected to the bumper cover, the extending walls are adjacent to the side walls so as to lock in position the stiffening member in the bumper arrangement.
- the stiffening member is substantially a C-shape in vertical cross section, having an elongated body portion and two arm portions extending away from the body portion, the arm being in use directed towards the vehicle.
- Fig.1 is a schematic side view illustrating a high fronted vehicle having a front bumper arrangement according to the invention
- Fig.2 is a perspective view from the inside of the bumper arrangement of Fig.1 ,
- Fig.3 is an enlarged scrap view of Fig.2,
- Fig.4 shows a schematic cross-sectional view through the line Ill-Ill in Fig.3,
- Fig.5 shows a schematic cross-sectional view through the line IV-IV in Fig.3
- Fig.6 shows a schematic cross-sectional view through the line V-V in Fig.4,
- Fig.7 shows a schematic cross-sectional view through the line Vl-Vl in Fig.4,
- Fig.8 shows a similar view as Fig.3 according to a modification of the present invention.
- Fig.9 shows a schematic cross-sectional view through the line VIII-VIII in Fig.8.
- a high fronted vehicle 10 such as a Sport Utility Vehicle and/or a 4x4 vehicle.
- vehicle 10 is conventionally provided with a bonnet 1 1 and a front bumper arrangement 12.
- the front bumper arrangement 12 is provided with a lower load path L, a centre load path C and an upper load path U arranged at different heights from the ground so as to limit the bending of the legs of a pedestrian in the event of a frontal collision.
- the bumper arrangement 12 comprises a bumper cover 20 and an upper grille bar 21 , both bumper cover 20 and grille bar 21 extending transversally across the front of the vehicle as seen in Fig.2.
- the bumper cover 20 extends also around the front corners of the vehicle 10.
- the bumper arrangement 12 is shown schematically when viewed from inside in Fig.2, and in cross section in Figs. 3 to 7.
- the grille bar 21 is provided to its rear side with a stiffening member 23, which extends across its entire length.
- the stiffening member 23 forms the upper load path U and is preferably located at a height of between 680 mm and 795 mm from the ground.
- the stiffening member 23 is preferably substantially a C-shaped in vertical cross section, having an elongated body portion 23a and two arm portions 23b, 23c extending away from the body portion 23a for cooperation with a slot 24 formed on a side wall 25 extending substantially at each end of the grille 21 .
- the grille bar 21 is also - A - provided with a housing 26 in which is accommodated the stiffening member 23, as shown in Fig. 7.
- the stiffening member 23 is made from different materials, such as steel alloys or aluminium alloys.
- the bumper cover 20 comprises a lower reinforcement forming the lower load path L and a deformable region forming the centre load path C.
- the deformable region is formed by the skin of the bumper cover cooperating with a foam, sufficiently weak to collapse under the force of a collision with a pedestrian, arranged on an armature of the vehicle.
- the stiffening member 23 is assembled to the bumper arrangement by engaging one end of the stiffening member 23 through the slot 24 of one of the side wall 25 of the grille
- Such a bumper arrangement 20 having a stiffening member 23 attached to the rear side of the grille bar 21 increases the resistance of the grille bar 21 to the rearward motion, hence reducing the bending angle of the legs and improving the pedestrian safety.
- the stiffening member 23 is attached to the housing by fastener means 30 such as bolts or similar so as to hold the member to the rear side of the grille bar.
- fastener means 30 such as bolts or similar so as to hold the member to the rear side of the grille bar.
- the stiffening member 23 could be a hollow member having a rectangular or circular or other cross section shape.
