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 vehicle includes a vehicle frame and a swing arm rotatably coupled to the vehicle frame at a rotatable connection. A track curves along a curved path. The track is fixed relative to the swing arm and spaced from the rotatable connection. An anchor is fixed relative to the vehicle frame. The track is slideably engaged with the anchor along the curved path of the track. A pyrotechnic actuator is between the vehicle frame and the swing arm.

A vehicle is provided. The vehicle may include at least one crush can, a controller and a pump. The crush can may include front and rear chambers. The controller may receive a first signal indicative of a loading condition generated at the time of an impact, and the pump may displace a nano-porous liquid in response to a second signal from the controller into at least one of the front and rear chambers of the crush can.

A load transmission structure includes: a rocker panel disposed to extend in a vehicle front-and-rear direction at an end portion in a width direction of a vehicle; an extension device provided with an extending member disposed at a position facing a wheel at an end portion of the rocker panel in the vehicle front-and-rear direction, the extension device being configured to operate to extend the extending member toward the wheel from the rocker panel; and a controller configured to operate the extension device when a collision of the vehicle is detected or predicted. The extending member is configured to include a metallic rod having an axial direction in the vehicle front-and-rear direction.

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.

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.

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 vehicle includes a frame, a wheel supported by the frame; and a device fixed to the frame. The device includes an inflator and an inflatable member in fluid communication with the inflator. The inflatable member is inflatable away from the frame and into contact with the wheel to push the wheel away from the frame during sensed impact of the vehicle.
