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 bumper for a vehicle includes a bumper crossbeam and two crash boxes extending away from a back of the bumper crossbeam. A one-piece blank made of fiber-reinforced sheet material extends from a wall section of the bumper crossbeam connecting the crash boxes, right into the crash boxes.

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.

An energy-absorbing member includes a fiber structure. The fiber structure includes a first end face configured to first receive a load and a second end face opposite to the first end face in the direction that the load is applied. The fiber structure includes a shape retention section including the first end face, a main section that includes the second end face and hinders propagation of breakage of the fiber structure, and a trigger section that is located between the shape retention section and the main section and serves as a starting point of breakage when receiving an impact load. The shape retention section and the main section each have a woven structure that allows the shape retention section and the main section to have a higher interlayer bonding strength than the trigger section.

A safety guard for a vehicle, such as a school or transit bus, includes a skirt extending below a side body portion of the vehicle and between front and rear wheels along a side of the vehicle. The skirt functions to push individuals and other animate objects out of the path of the wheels for safety purposes, while being mounted for separate linear and arcuate movements relative to the body of the vehicle to protect the guard from damage upon abutting an inanimate object during operation of the vehicle.

A mobile platform including a vehicle body, an elastic anti-collision strip and two trigger mechanisms is provided. The vehicle body has two side surfaces and a front side surface connected between the two side surfaces. A safety network is provided in the vehicle body. The elastic anti-collision strip includes an impact receiving section and two fixing sections respectively connected to the impact receiving section. The impact receiving section is arc-shaped and located on the front side surface. The two fixing sections are respectively fixed to the two side surfaces. The two trigger mechanisms are respectively fixed to the two side surfaces and connected to the two fixing sections. The trigger mechanisms are used to trigger the safety network according to a deformation condition of the impact receiving section. The two fixing sections are used to control the deformation condition. A driving method of the mobile platform is also provided.
