A motor vehicle deformation device has two elements moveable together in a collision event and optionally locked. A locking device has a first centrifugal lever pivotably mounted about a first pivot axis located on the first element, a first torsion spring operatively connected to the first lever, a first rolling surface and a first contact surface arranged distally to same, as well as an identically designed second centrifugal lever neighboring the first lever. In a low-speed collision, the two levers each swivel such that the two rolling surfaces are in contact with one another and the two contact surfaces each rest against a corresponding receiving surface on the second element. In a pedestrian accident situation, the two levers each swivel such that the two rolling surfaces are in contact with one another, while the first and second contact surfaces are at a distance from the second element.

A covering of an outer sill of a vehicle, in particular a motor vehicle, has a covering region and a mounting region, which extend between first and second ends of the covering along a direction of longitudinal extension. The mounting region extends in a first direction of transverse extension perpendicular to the direction of longitudinal extension and has mounting elements in order to be able to be mounted on an underside of the outer sill for a mounted state. The mounting region has a lateral edge facing away from the covering region in the direction of longitudinal extension, which has recesses between mounting elements, which are formed such that sections of the lateral edge of the mounting region extend in a recessed manner in the first direction of transverse extension towards the covering region.

A motor vehicle has a container for receiving liquids arranged in a motor compartment of the motor vehicle in a space-saving manner. The two front end sections of the two front axle supports are connected together by two transverse supports, which are arranged at a distance from each other in the vehicle longitudinal direction, and the container for receiving liquids is arranged in the intermediate space between the two front axle supports.

Motor vehicle

A pedestrian protection device for a motor vehicle, in particular for a front part of the motor vehicle, includes a bumper crossbeam and a deformation element arranged in front of the bumper crossbeam. The deformation element has a bending section, the end of which is in contact with a surface or which comes into contact with the surface in the event of a collision, in particular a front collision of the motor vehicle. The end of the bending section is designed such that it can move along the surface as a result of the collision, wherein the surface has an engaging device with which the end of the bending section can be, in particular, engaged.

Pedestrian protection device for a motor vehicle

A pedestrian protection device for a motor vehicle includes a bumper crossmember and a deformation element which is arranged on the bumper crossmember and which has a first element and a second element which are displaceable relative to each other in the event of a collision of the motor vehicle, and a mechanical locking mechanism. The locking mechanism has a movable locking element which is pretensionable or is pretensioned with a spring device and which is arranged on the first element or on the second element, and with a depression or step to which the other of the first element and the second element can be latched in a form-fitting manner. In the event of a high displacement speed which is greater than or equal to a predetermined second displacement speed, the locking mechanism prevents displacement of the first element relative to the second element by means of self-locking of the locking element. In the event of an average displacement speed which is lower than the predetermined second displacement speed and greater than a predetermined first displacement speed, the locking mechanism permits displacement of the first element and of the second element relative to each other.

A deformation structure has at least a first layer and a second layer, which are spaced apart from each other and displaceable relative to each other in the deformation direction or load direction. The first layer and the second layer have complementary protrusions and recesses, which are designed in such a way that the protrusions of the first layer can plunge into the recesses of the second layer and the protrusions of the second layer can plunge into the recesses of the first layer. The first layer and the second layer are connected to each other by deformable webs in such a way that, in the event of a high impulse in the deformation direction, the protrusions of the first layer plunge into the recesses of the second layer and the protrusions of the second layer plunge into the recesses of the first layer such that deformation of the deformation structure in the deformation direction occurs at a relatively low force level and, in the event of a low impulse in the deformation direction, the protrusions of the first layer hit the protrusions of the second layer such that further deformation of the deformation structure in the deformation direction occurs at a relatively high force level.

Deformation structure and pedestrian protection device having a deformation structure

A pedestrian protection device for a motor vehicle, for example for a motor vehicle front end or a motor vehicle rear end, has a bumper crossmember with a deformation element arranged on the outer side thereof, i.e. the side directed towards the front. In particular, the deformation element is arranged between a bumper skin and the bumper crossmember. The deformation element has a first element and a second element which are displaceable relative to one another in the event of a collision. Furthermore, the pedestrian protection device has a locking mechanism which, in dependence on a displacement speed, and thus on a collision speed, of the motor vehicle, and while exploiting a mass inertia of a locking element which is arranged or mounted on the first element or the second element, is adjustable between a locked state in which a displacement of the first element relative to the second element is at least partially prevented by, in particular, positive engagement, and an unlocked state in which a displacement of the first element is allowed.

To improve the safety of passengers of a motor vehicle and road users in the case of a head-on collision, a deformation element is provided and includes a crossmember holder for mounting to a crossmember and a bumper plate that can be positioned next to a bumper of a motor vehicle. The deformation element is characterized in that a centrifugal force-operated release element for adjusting and locking the distance of the crossmember holder from the bumper plate is provided between the bumper plate and the crossmember holder. A first distance of the bumper plate from the crossmember holder, starting from a normal position, is greater in a first position than a distance in a second position.

A bumper device for a motor vehicle has two bumper support members arranged parallel to the vehicle longitudinal center plane. The bumper device has a bumper crossmember arrangement arranged transversely with respect to the vehicle longitudinal center plane. The bumper crossmember arrangement has two fastening portions at which the bumper crossmember arrangement can be fastened to the associated bumper support member directly or by a respective connecting structure. A central portion between the fastening portions and two lateral end portions protrudes beyond the fastening portions. The central portion of the bumper crossmember arrangement is designed as a frame member surrounding an opening, with an upper crossmember, a lower crossmember, a left support post and a right support post.

Bumper device for a vehicle

To improve the safety of passengers of a motor vehicle and road users in the case of a fronted collision, a deformation element is provided and has a cross-beam holder for mounting to a cross-beam and a bumper plate that can be positioned next to a bumper of a motor vehicle. The deformation element is characterized in that a friction device for adjusting and fixing the distance of the cross-beam holder from the bumper plate is provided between the bumper plate and the cross-beam holder, a first distance of the bumper plate from the cross-beam holder, starting from a normal position, being greater in a first position than a distance in a second position.

A front end assembly for a motor vehicle has improved load absorption for forces acting on the front of the front end assembly. The front end assembly has at least one impact-absorbing crossbeam; at least one support beam which can be arranged vertically on the motor vehicle and towards the rear of the impact absorbing crossbeam, can be secured to a motor longitudinal support of the motor vehicle, and has at least one upper end portion that can be arranged at least partly above the motor longitudinal support. At least one support strut extends rearwards and downwards from the impact-absorbing crossbeam and via which the forces acting on the front of the impact-absorbing crossbeam can be partly transmitted to a front axle support of the motor vehicle. At least one deformation element can be arranged at least partly geodetically higher than the impact-absorbing crossbeam and in front of the upper end portion of the support beam at least partly on the front side, and is supported at least partly rearwards against the upper end portion of the support beam at least while deforming.

Front end assembly for a motor vehicle

A deformation structure, which is an energy absorption structure, has a series of deformation elements arranged one behind the other in a deformation direction, i.e. the direction in which a load acts. Each two adjacent deformation elements are coupled together by a coupling mechanism, such that in a first load case, in particular a first collision load case, two adjacent deformation elements enter into a latching engagement with one another or are positioned in a latching engagement, such that a relative displacement of the adjacent deformation elements with respect to one another in the deformation direction is prevented, or at least made more difficult, and a deforming of the deformation structure occurs at a high level of force, and in a second load case, in particular a second collision load case, two adjacent deformation elements do not enter into the latching engagement or leave a latching engagement, such that a relative displacement of the adjacent deformation elements in the deformation direction is enabled, or at least made easier, and a deforming of the deformation structure occurs at a low level of force.

A deformation element arrangement is provided for a motor vehicle, having a deformation element and a vibration-generating device. The vibration-generating device is arranged and designed in such a way that the deformation element, when required, can be set in vibration so that a deformation behavior and/or a flow behavior of the deformation element is/can be varied in accordance with a request condition.

An arrangement for absorbing kinetic energy acting on a front bumper of a vehicle, in particular a motor vehicle, includes at least one pedestrian protection element which can be arranged on a cross member of the bumper, at least one absorption element which can be arranged on the cross member and is movable on the cross member in the longitudinal direction of the vehicle relative to the cross member between a front absorption position and a rear release position, and at least one locking device which can be arranged on the cross member by which the absorption element can be temporarily arrested in the absorption position thereof. The absorption element, in the absorption position thereof, is switched parallel to the pedestrian protection element in respect of a force initiated by the kinetic energy into the bumper.

A support device for a front end of a passenger motor vehicle includes at least one vehicle body component extending in the vehicle vertical direction, by which respective longitudinal support elements, which are associated on the sides, of respective longitudinal support planes are connected to each other. A transverse support of a front end module is retained on the body of the passenger motor vehicle. At least a first support element is provided on the body component on a side facing outwardly in relation to the transverse direction of the vehicle and has a receptacle. At least a second support element is arranged outside of the body component in relation to the transverse direction of the vehicle, provided on the transverse support and extends rearwardly from the transverse support. In an initial state of the support device, the second support element is spaced apart from the first support element and, as a result of a corresponding accident-caused application of force, it is displaced at least partially into the receptacle, thereby supporting the first support element.
