Definitions
- Motor vehicles are equipped with a shock absorption system adapted to manage frontal impacts between the vehicle and a pedestrian, in particular at the level of his legs.
- the objective is, on the one hand, to absorb the energy of the impact, and on the other hand, to limit the injuries inflicted on the pedestrian and to prevent him from passing under the vehicle.
- the shock absorption system generally comprises two parts, a part called the “lower track” and a part called the “higher track” and the pedestrian impact performance at the level of the legs is ensured by a compromise of stiffness between the high track and the lower track.
- the low track is positioned at the central deflector of the front bumper of the vehicle and will “whip” the lower leg of the pedestrian in order to prevent the latter from passing under the vehicle.
- the high track is, for its part, positioned at the level of the front bumper beam of the vehicle and allows the energy of the impact to be dissipated, in order to limit injuries to the pedestrian.
- the objective is to lay the leg as much as possible in order to limit the shearing of the knee.
- the high track includes an energy absorption device called a “leg absorber”, which is located between the bumper beam and the bumper skin of the vehicle. The crushing of the leg absorber, during a collision, will place the high track in a position further back than the low track relative to the vehicle, thereby causing the pedestrian’s leg to lay down in the direction of the hood of the vehicle.
- Such a device for example in the form of a polypropylene foam absorber, is for example described in document EP3300963B1.
- Such a device has proven to be satisfactory and effective with regard to frontal impacts of the pedestrian type and repairability impacts.
- Document CN101084140B relates to a vehicle bumper system comprising a beam and a thermoformed energy absorber, positioned on a face of the beam.
- the thermoformed energy absorber comprises a plurality of elongated crush boxes thermoformed from a base flange.
- the central zone has a less aggressive impact, intended to reduce pedestrian injuries upon impact.
- This configuration is interesting but insufficient during pedestrian impacts at the outer edge of the bumper.
- the invention aims to address at least one of the problems and drawbacks encountered in the prior art.
- a solution remains to be found to improve the performance of a vehicle in terms of pedestrian protection during an impact on the outer edge of a bumper.
- the invention relates to a vehicle with a front shock absorption system comprising longitudinal stretchers, upper absorbers arranged as an extension of said longitudinal stretchers and an upper beam transversely connecting the upper absorbers, the upper beam having two ends and lateral extensions at its ends, the front shock absorption system further comprising an assembly forming a bumper comprising a bumper skin and at least one reinforcing element; the vehicle being remarkable in that and in that at least one reinforcing element comprises a lateral absorber arranged opposite one of said lateral extensions.
- the invention is remarkable in that it will place deformable absorbers on the outer edge of the bumper, by fixing said absorbers (called lateral absorbers) to the assembly forming a bumper and not to the upper bumper beam.
- the lateral absorbers are not in contact with the bumper beam but opposite it.
- Their positioning on the assembly forming a bumper and preferably on a bumper skin reinforcement provides it with stability preventing it from sliding on or under the upper beam during impact kinematics and therefore avoids generating non-optimal behavior in collision kinematics.
- the assembly forming a bumper comprising a bumper skin and at least one reinforcing element the vehicle is remarkable in that at least one lateral absorber is made in one piece with at least one reinforcing element.
- the lateral absorbers are positioned under the vehicle's lights and do not risk sliding on the upper beam during the impact and therefore causing non-optimal behavior.
- the reinforcing element and the lateral absorber are made of a plastic or composite material comprising at least 30% recycled plastic resin. The addition of recycled material makes it possible to reduce the ecological footprint of the vehicle.
- the lateral extensions extend from the ends of the upper beam towards the rear of the vehicle in a direction forming an angle of between 5 and 30° with the transverse direction of the vehicle.
- the lateral extensions are elements making it possible to absorb the transverse components of “small overlap” type impacts according to the standards in force in the United States. Their orientation towards the rear of the vehicle at a given angle makes it possible to adapt to the style of the vehicle.
- each or at least one of the lateral absorbers has a rear face intended, during an impact, to be placed in support on the lateral extension opposite which it is arranged, said rear face is configured to have an angle similar to or equal to that of said lateral extension.
- This arrangement will create optimal absorption conditions but also guarantee the dissipation of energy during an impact.
- the rear surface of the lateral absorber will match the surface of the lateral extension, so that the absorber comes into contact with the lateral extension over its entire support surface.
- each or at least one of the lateral absorbers is in the form of a hollow box. This makes it possible in particular to mold the reinforcement and the lateral absorber in a single piece, the lateral absorber then being in the form of a hollow box open on one of its faces.
- each or at least one of the side absorbers has a structure showing folds or grooves configured to generate progressive deformation kinetics.
- the side absorber(s) may have a design similar to the upper or lower absorbers.
