A network structure is formed in a three-dimensional mesh shape in which a plurality of polyhedron frames are arranged. Each polyhedron frame is formed by a plurality of apexes disposed in a three-dimensional space and connecting members for connecting the apexes. The plurality of polyhedron frames are regularly arranged so that the polyhedron frames are displaced at a constant degree when a constant load is applied.

The invention relates mainly to an energy absorber for an aircraft seat, notably for a helicopter seat, comprising at least one energy-absorption element having: a first anchor point and a second anchor point, an energy-absorption zone extending between the first anchor point and the second anchor point, said energy-absorption zone being able to stretch as a tensile load is applied between the first anchor point and the second anchor point, characterized in that the energy-absorption zone has a meshed structure comprising a plurality of strands connected to one another by junction portions, and in that at least one junction portion provides a junction between at least three strands of said energy-absorption zone.

A shock absorber capable of suppressing load fluctuation after the start of plastic deformation. The shock absorber formed of a hollow molded body, including a load input surface; a fixed surface opposed to the load input surface; and a connection surface connecting the load input surface and the fixed surface. The connection surface includes at least one transverse groove rib, the at least one transverse groove rib includes at least two bending induction portions provided at positions where distances from the load input surface are different from each other, the at least two bending induction portions each being convex toward an outside of the shock absorber.

Methods and apparatus are provided for a shock attenuation device configured for use in conjunction with a body movably mounted to a structure along a stroking direction to attenuate shock loads associated with a high energy impact event on the structure. The device includes an elongated metal frame with left and right sides symmetrically disposed about a longitudinal slot extending from proximate a first end of the frame to a second end. The frame is mountable to one of the body and structure in an orientation causing the longitudinal slot to align with the stroking direction. A mandrel mountable to the other one of the body and structure is positioned in the frame at one end of the slot. The mandrel has width and length dimensions measured in the plane of the frame, wherein a maximum width of the mandrel is greater than a width of the slot.

An aesthetically pleasing docking station that is able to support electronic devices with only an interface connector. The docking station is further equipped with mechanisms that protect the electronic device from damage if it's deflected too far while mated to the docking station.

A steering column may include a sleeve unit in which a steering spindle rotatably mounted about a longitudinal axis, which sleeve unit is accommodated in a supporting unit so as to be displaceable in a longitudinal direction. An energy absorption device may be fitted between the supporting unit and the sleeve unit. The energy absorption device may include first and second bending elements that each comprise an elongate input limb positioned parallel to the longitudinal direction and connected at a free end to the supporting unit or the sleeve unit, and merges at another end into a bend to which a fixed limb is connected. The fixed limb may be connected to the other of the supporting unit or the sleeve unit. The second bending element may be formed in a mirror-inverted manner relative to the first bending element and may be positioned mirror-symmetrically adjacent to the first bending element.

An energy absorption element for a steering column of a motor vehicle may comprise a deformation element, a first fastening element, and a second fastening element. The deformation element may be connected to the first fastening element and to the second fastening element and is arranged in a force flux with respect to a force that can be exerted on the first fastening element relative to the second fastening element. To achieve improved security against damage due to unauthorized use or inadvertent damage and, in the process, requiring little outlay on manufacturing and installation, a predetermined breaking element may be connected to the first and second fastening elements parallel to the deformation element in the force flux.

A shock absorber includes a bottom rim, a top wall comprising a raised central portion and a top rim, a side wall extending between the top and bottom rims, and a corrugation surrounding a periphery of the raised central portion that (i) connects the raised central portion to the top rim, (ii) descends to a depth below half a height of the side wall, and (iii) is separated by a distance from a surface. Impact forces imparted on the shock absorber are attenuated by a first amount in a first stage by resistive yielding of the side wall; by a second amount in a second stage by depression of the central portion and resistive yielding of the corrugation associated therewith; and by a third amount in a third stage by resistive yielding of the corrugation in response to a force applied to the top rim upon contact with the surface.

A method includes coupling a damper to a cable and a load, and moving the damper, the cable, the load, or a combination thereof. In response to the movement, slack is introduced into the cable, and the slack is suddenly released, which exerts a tensile load on the damper and the cable. The damper is configured to dampen the tensile load exerted on the cable.

A pedestrian protection device for a motor vehicle having a windscreen and an A-pillar extending adjacent a side edge of the windscreen. The protection device comprises a base member securable to the A-pillar of the motor vehicle, and a trim member moveable relative to the base member. A deployment mechanism is operable upon actuation of the device to drive the trim member away from the base member from an initial position in which the trim member is proximal to the base member, to a deployed position in which the trim member is spaced from the base member. The deployment mechanism comprises a plastically deformable member interconnecting the base member and the trim member and which is arranged, in said deployed position of the trim member, to absorb impact energy arising from impact between a pedestrian and the trim member in compression.
