A front bonnet part covering the front edge of the bonnet is arranged at a function position (35.1) and moved into an impact absorber (40.1) relative to the function position during the movement of the bonnet from an initial position into the function position. The damper partially encompasses the front edge in direction of the side edges.

Description

The The invention relates to an arrangement of, preferably as a front end carrier designed, Frontendbauteils and a front door, in particular a bonnet, such as a bonnet, and at least a carrier component, in particular a raw and a body component, for a vehicle, or a vehicle, in particular motor vehicle / s.

Around the risk of injury and the extent of injury or the Injury level in the collision of a vehicle in its front area to reduce with a pedestrian are a variety of Constructions have become known. Among them are those at sensor-controlled shortly before the collision and / or during the collision and / or as a result of collision with a pedestrian the distance of the front or bonnet to the underlying Vehicle parts, in particular to the engine, by means of a device for raising the front or bonnet of its closed normal or basic position to a protection or functional position is increased.

Such constructions are for example from the DE 103 14 968 A1 , of the DE 699 00 755 T2 , of the DE 694 00 889 T2 , of the DE 101 52 621 A1 , of the DE 197 12 961 A1 , of the DE 102 58 627 A1 , of the DE 10 2004 055 603 A1 or the WO 2005/102793 known.

Among them are such constructions in which only the trailing edge of the front door, so only the rear in the direction of travel or adjacent to a windshield edge is raised, while the front edge of the front door, ie the front in the direction of travel or away from the windshield pointing edge, essentially remains in place or is slightly lowered in the course of pivoting about a trained perpendicular to the direction of travel and fixedly arranged transverse axis. Such constructions are for example from the DE 699 00 755 C2 , of the DE 694 00 889 T2 or the DE 197 12 961 A1 known. In these constructions, however, during the lifting of the front bonnet trailing edge it shifts in the forward direction, so that in extreme cases even an increase of the impact energy with the consequence of an increased risk of injury and a greater degree of injury can occur. In addition, in these constructions when folding the front door only a rearward increasing distance between the front door and the vehicle parts underneath created so that the front is a correspondingly limited, decreasing Verformungsweg to intercept the force or impact energy of a pedestrian available.

In order to avoid these disadvantages, constructions have been developed in which, in the event of a collision, not only the rear area but also the front area of the front flap is raised. Such constructions are for example from the DE 101 52 621 A1 or the DE 103 14 968 A1 known. The DE 101 52 621 A1 relates to an arrangement of a front door on a vehicle, with a viewed in the direction of travel, rear hinge means which is mounted on the one hand on the front door and on the other hand on the body, and about which the front door for normal opening is pivotable. The front flap is raised in a collision of the vehicle with a pedestrian in the rear area power-operated, and it is forcibly also raised in the front by raising its rear portion by a mechanical coupling, in such a way that a rearwardly tilted movement proportion arises which is used to raise the front area of the front flap over a slotted guide back up. By this, backward movement proportion of the front flap increases the protective effect, because the relative speed between the impinging pedestrian and the front flap is reduced. In addition, this can be minimized when setting up the front door possibly between the windshield and the front flap resulting gap, whereby the risk of injury, especially the head injury risk, is further reduced. Finally, may be associated with such a construction, the advantage that the erection of the front door is supported by the pedestrian impact itself, so the impact energy introduced in the front flap can be at least partially used to support the erection of the front door. However, with this construction, as the front flap is displaced rearward and upward between the leading edge of the front door and an upstream portion of the vehicle, an increasing gap is formed, thereby increasing the risk of injury, particularly the hip and thigh injury risk and the risk of more severe injury.

One in terms of their function and their advantages and disadvantages, similar construction, is from the DE 103 14 968 A1 known. The hood is connected via four, arranged at their side edges hinges with the shell, of which two hinges in the rear edge of the hood and two hinges in the region of the front edge of the hood are arranged. In the hinges are each two spaced joints, formed with articulated arms, identical hinges, each with the same length, the rear joint hinges are designed as four-joint hinges, each with two identical articulated arms of equal length. When transferring the front flap from its normal position to its rearwardly and upwardly raised protective position, therefore, a parallel displacement of the front flap relative to the shell takes place to the rear and above.

The from the two aforementioned publications resulting constructions However, they have the disadvantage that in the respective protective position, in which the respective front flap in a furthest moved backward end position, the leading edge the front flap is in a maximum raised position. In this end position, however, harbors the raised front edge the front door a significant risk of injury, especially regarding Injuries to the thigh and / or hip a pedestrian.

From the DE 10 2004 055 603 A1 a safety device for a vehicle has become known, which comprises a lifting device, by means of which the front hood of a vehicle can be raised in the case of a detected, imminent or completed collision of the vehicle by a sensor device, from a hood basic position to a raised hood functional position, namely to form a joint between the vehicle body and a hood edge region. This safety device has a joint covering element, by means of which the joint is at least partially coverable and which is formed by a displacement element, which is displaced by a covering element rest position in a cover element covering position at an increase in the hood of or by means of the hood , In this case, the joint covering element, which may be an existing from a foam material or designed as a covering energy absorption element, attached both to an outer hood cover part and on an inner hood inner part of the two-piece front hood, said the hood inner part can be designed as a hood frame. When lifting the hood outer part relative to the hood inner part up it comes between the front edge of the hood outer part of the front hood and the adjacent fender of the vehicle to form a joint, in which when lifting the front edge of the hood outer part upwards the energy absorption element of the also formed with a band, mechanical displacement element, is transferred to cover this joint. By raising the hood outer part of the band, which is attached on the one hand to the hood outer part and the other part of the hood inner part, tightened, thereby characterized the originally between the hood inner part and the hood outer part biased arranged energy absorbing element to cover the joint the same is displaced into the joint with simultaneous relaxation, whereby a broadening of the hood edge region can also be achieved. However, this construction is not applicable to front hoods, which are shifted in the event of a collision upwards and to the rear, because it can then come to an insufficient coverage of the joint or an even open gap and a correspondingly increased risk of injury.

From the WO 2005/102793 is a backup device has become known, which is formed with a bridging element, which is attached to a relative to the front hood angled down front cover by means of predetermined breaking attachment points and that is also attached to a headlight module and deformable in this latter area. When lifting the front cover up the attached to the cover element bridging element, which may consist of a deformable material, in particular of plastic, moves together with the front cover in a raised securing position. This creates a gap between the bridging element and the adjacent body, which means an increased risk of injury. This can only be mitigated in this construction by the fact that or if it comes due to the intended breaking points in the event of a collision to a separation of the bridging element of the cover. However, by loosening the bridging element on impact of a pedestrian this moves uncontrollably through the air, which ultimately means again increased risk of injury.

From the FR 28 75 771 For example, there has been disclosed a three-impact armor guards, each having different energy absorption characteristics, offset from each other in height, attached to a front end support and having a reinforcement disposed in the lower portion of main headlights between the main headlights. This latter reinforcement may consist of a polyurethane foam.

It has now in extensive practical tests in connection shown with a movement analysis in the front impact of dummies, that it should be possible, the risk of injury and / or the To further reduce degrees of injury.
