A metal shock absorption element having a first metal sheet and a second metal sheet. The first metal sheet is shaped in the form of a longitudinally open metal profile and has a substantially “C”-shaped cross-section. The second metal sheet is shaped in the form of a longitudinally open metal profile and has a substantially “C”-shaped cross section. The second metal sheet is inserted in a first longitudinal channel of the first metal sheet. The second metal sheet is made integral in one single piece with the first metal sheet in a collection of points to create a metal honeycomb structure having a closed cross-section and metal channels.

A crash box may include one or more layers arranged to absorb crash energy. In some embodiments, the crash box includes a first layer having an outer skin defining a periphery of the first layer and at least one of: 1) a rib and web structure, and 2) an array of tubes disposed within the outer skin for absorbing crash energy, and a second layer adjacent to the first layer, the second layer having an outer skin defining a periphery of the second layer and at least one of: 1) a rib and web structure, and 2) an array of tubes disposed within the outer skin for absorbing crash energy.

An impact energy absorbing device for a vehicle includes a plurality of cells that are grouped together to form a matrix structure defining a mounting region and a contact region. The cells crush along their respective longitudinal axes when exposed to an impact force on the contact region. Each of the longitudinal axes of the plurality of cells in the matrix structure diverges with respect to neighbouring cells in a direction from the mounting region to the contact region.

A rail extension system (16), comprising: a vehicle rail (60); a bumper beam (20); a polymeric rail extension (1) comprising: a base (2) extending from one end of the rail extension having vehicle attachment configured to attach to the vehicle rail (60); a front member 4) configured for attachment to the bumper beam (20); a body (5) extending from the base (2) to the front member (4); an aperture (100) extending from the base (2) to the front member (4); a connection member (102) attached to the bumper beam (20) and extending through the aperture (100) to attach to the vehicle rail (60).

The present disclosure relates to a Vehicle front structure as defined above is provided, in which the front structure comprises: a side member for supporting a vehicle bumper beam, the side member extending along a longitudinal axis between a first end for connecting to the vehicle bumper beam and a second end for connecting to a bulkhead, and a lateral extension member extending substantially perpendicular with respect to the longitudinal axis of the side member and outward with respect to the vehicle front structure, the lateral extension member is connected to the side member such that the lateral extension member can exert a bending moment to the side member, and a bending strength of the lateral extension member in backward direction towards the side member is higher compared to a bending strength in the forward direction away from the side member.

A crash can for a vehicle includes a multi-cell structure that includes at least four hollow cuboids, each defined by four walls that meet at 90 degree angles and at least two of the cuboids share a wall. In another example, a crash can includes a multi-cell structure that includes a hollow cuboid having four walls, and four hollow isosceles trapezoidal prisms having a long base, a short base, and two legs. The multi-cell structures provided herein may increase energy absorption by the crash can if involved in a collision, reducing energy transfer to a vehicle frame and occupants therein.
