A vehicle bumper assembly is provided having an energy absorber, a bracket, a step pad and a bumper fascia. The energy absorber includes an upper horizontal surface wherein the upper horizontal surface may define a deformable structure. The deformable structure may be in the form of flexible fins. The bracket may be mounted to the vehicle frame on a first end of the bracket and the energy absorber affixed to a second end of the bracket. The step pad may be affixed to the energy absorber. The bumper fascia may be affixed to either or both the step pad and the energy absorber.

A vehicle body including side is provided. The vehicle body includes left and right side frames that extend in a vehicle body forward-rearward direction and support a collision load acting from the front or the rear, and a coupling member that is joined to open ends of the side frames and restricts displacement between the open ends in a direction in which the open ends are away from each other. The side frame has a plurality of low-strength sections disposed with high-strength sections interposed therebetween in the vehicle body forward-rearward direction and having a lower strength than the high-strength sections in the vehicle body forward-rearward direction. The low-strength section closer to the open end has a lower strength in the forward-rearward direction.

A safety bumper assembly for a vehicle shutting off a vehicle engine when the vehicle hits an obstacle, particularly an autonomous vehicle used for agricultural purposes. The assembly includes bumper shafts holding a bumper bar at a distance from a support structure of the vehicle and shuts off the vehicle engine in such fashion that the vehicle comes to a full stop before the bumper has reached its most inward position closer to the vehicle body. A vehicle equipped with the safety bumper assembly has vehicle frame integrating a support structure of the safety bumper assembly.

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 profile strut includes an upper chord, a lower chord, two spaced-apart lateral walls which, together with the upper chord and the lower chord, define an interior, and a first profile end and a second profile end. A first end piece is disposed in the first profile end and a second end piece is disposed in the second profile end. A connecting web connects the first end piece to the second end piece. Each of the first end piece and the second end piece bears via end faces thereof against adjacent inner wall regions of the upper chord and the lower chord; respectively. An intermediate region, which is configured as a tunnel incorporated into the lower chord, is disposed between the first profile end and the second profile end.

Embodiments of a crush box are described. One embodiment of the crush box includes a first sidewall that is coupled to a vehicle and a second sidewall that is coupled to the vehicle, where the first sidewall and the second sidewall include similarly pre-bent portions that cause the first sidewall and the second sidewall to bend outward upon receipt of a force. In some embodiments, the first sidewall and the second sidewall include a plurality of tabs that couple the first sidewall and the second sidewall to a top wall that bends inward upon receipt of the force.

A vehicle body front structure includes left and right front side frames including at least left and right front bending portions, left and right middle bending portions, and left and right rear bending portions. The left and right front bending portions are bent to project inwards in a vehicle's width direction by a collision load exerted on a front end of a vehicle body, whereby the left and right front bending portions restrain a power unit. The left and right middle bending portions are situated spaced apart to the rear from the left and right front bending portions. The left and right rear bending portions are situated spaced apart to the rear from the left and right middle bending portions, are bent outwards in the vehicle's width direction, and absorb collision energy when struck by the power unit moved rearward together with the left and right front bending portions.
