A vehicle door includes an interior panel including a housing extending from a first side of the interior panel and defining a cavity. An energy absorption structure is positioned within the cavity and includes a plurality of members arranged in a plurality of rows. Each of the plurality of members includes at least one arcuate support coupled with a rib and having first and second ends. The at least one arcuate support of each member is coupled to the at least one arcuate support of a neighboring member at one of the first and second ends.

The invention relates to a crash structure for a motor vehicle, comprising a carrier body, from the carrier surface of which at least one deformation unit formed integrally with the carrier body protrudes, which deformation unit is formed by at least two deformation elements arranged one over the other and connected to each other and by an impact surface, wherein: a longitudinal section of each deformation element has two longitudinal section surfaces lying opposite each other and following respective non-straight curves; the impact surface is spaced apart from the carrier surface by the deformation elements.

An energy-absorbing assembly includes a housing and a plurality of discrete energy-absorbing elements. The housing includes a first wall and a second wall. The first wall and the second wall are spaced apart from one another to at least partially define an interior compartment. Each element of the plurality of energy-absorbing elements includes a polymer and a plurality of reinforcing fibers. The plurality of energy-absorbing elements is at least partially disposed within the interior compartment and fixed to the housing. Each energy-absorbing element of the plurality of energy-absorbing elements includes an elongated hollow structure extending between a first end and a second end. Each elongated hollow structure defines a longitudinal axis extending nonparallel to at least one of the first wall and the second wall. In various alternative aspects, each energy-absorbing element may include a transverse wall.

A vehicle framework component includes a hollow member and a reinforcing member. The hollow member includes therein mutually facing first surface and second surface. The reinforcing member, which includes a cylindrical tube having a quasi-circular cross section, stands on the first surface or the second surface inside the hollow member.

A strengthening structure of a vehicle is provided that comprises a base having a first plurality of cutouts and relief members disposed across the base. Each relief member includes a cross section having a plurality of corners forming a plurality of inner and outer angles, a distal end, and an open proximal end in communication with one of the first plurality of cutouts.

Energy conversion systems and methods are disclosed. In one aspect, the system is for converting or redirecting energy received by an impact to an automobile in a proximal direction into another type of energy. The system includes a body having a first engagement structure and an impact member configured to be installed within an outer perimeter compartment of the automobile to receive an impulse. The impact member having a second engagement structure and a third engagement structure. The second engagement structure being configured to engage with the first engagement structure of the body to facilitate the impact member translating in the direction relative to the body. The system further includes a converter having a fourth engagement structure, the fourth engagement structure being configured to engage with the third engagement structure of the impact member and convert the energy received by the impact member into another type of energy. The system may change or redirect a direction of a force vector associated with the received impulse.

An apparatus includes a bumper beam including an outer face, a plate elongated along the outer face, a plurality of ribs elongated from the plate transverse to a direction of elongation of the plate, and a plurality of cylinders each fixed to one of the ribs and spaced from the plate.

A bumper assembly includes a bumper elongated along a first axis. The bumper assembly includes a first energy absorbing device extending from the bumper, the first energy absorbing device having a second axis perpendicular to the first axis, the first energy absorbing device being elastically deformable along the second axis. The bumper assembly includes a second energy absorbing device within the first energy absorbing device and being shorter than the first energy absorbing device.

The present invention relates to a novel idea of Automobile Collision Impact Reducer(ACIR) which can be placed at the front, rear, sides between the doors of an automobile with multi chambered springs of various strengths which can be arranged in different patterns, multilayered plates, pipes and multilayered cushioning materials acting also as fire suppressant. In-order to reduce the recoil effect after the compression of springs, Recoil Arrester/Lock system is introduced having recoil arresting box, recoil arresting plate, tension springs and recoil lock lever. This concept can also be used in crash guard barriers in the roads, culverts and pillars of bridges, walls of houses near the road turns, pillars of metro rail, other railway lines etc with certain modifications. During the time of collision, after the force transfers from the cushioning materials, there will be multi chambered compression of springs depending on its stiffness which helps to reduce the impact.
