The present impact absorbing member includes: a hat-shaped member having a hat top section; and a plate-shaped member facing the hat top section. A deformation guidance section is provided on a wall section of at least one of the hat top section and the plate-shaped member. The deformation guidance section includes: a first high strength section having relatively higher buckling resistance in the wall section; and a pair of low strength sections having relatively lower buckling resistance and arranged on both sides of the first high strength section therebetween in a view along the longitudinal direction. Furthermore, the impact absorbing member includes a pair of second high strength sections disposed on both sides of the deformation guidance section to be adjacent to the pair of low strength sections in a view along the longitudinal direction and having a higher buckling strength relative to the low strength sections.

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 steering column assembly includes a lower jacket assembly extending along a steering column axis. Also included is an upper jacket assembly at least partially received within the lower jacket assembly, the upper jacket assembly translatable along the steering column axis relative to the lower jacket assembly. Further included is an energy absorption strap operatively coupled to the upper jacket, the energy absorption strap having an aperture defined therein. Yet further included is a rake bolt extending through the lower jacket and through the aperture of the energy absorption strap.

Provided is a vehicle steering column. A lower column has an open area, an axial slot provided in a central portion of the open area, a connecting portion connecting portions of the lower column located on both sides of the open area, a cut portion corresponding to the slot and provided on one side of the connecting portion, and a pair of protruding opposite end portions. A hinge pin is fitted into the opposite end portions of the lower column. An upper column is fitted into the lower column. A telescopic fixing plate of the upper column is provided in a location corresponding to the slot, and has a plurality of catch recesses spaced apart from each other. A telescopic catch member is located in the cut portion between the opposite end portions to be rotatably supported by the hinge pin, and has a catch protrusion engaging with the catch recesses.

An energy absorption device for a vehicle steering column comprising a metal band and an adjustable deformation unit through which the metal band extends. The deformation unit is a rotatable hollow roller having a first contact surface inside the hollow roller that is separated from an outer contact surface by an outlet slot. The metal band passes through an inlet slot into the interior of the roller, and then through the outlet slot leaves the roller, in a manner that that said metal band is entirely deformed along an S-shaped curve.

Methods and apparatus are provided for a shock attenuation device configured to operate between a structure and a mass that is supported by and moveable relative to the structure in a guided manner along a stroking direction. In one embodiment, a notch load portion is configured to provide a resisting force to relative displacement of the supported mass over a first stage stroking distance according to a predefined load profile that includes a spike load peaking at a first threshold load value at the onset of relative displacement, and a substantially constant notch load for a remainder of the first stage stroking distance. A constant load portion arranged serially with the notch load portion is configured to provide a substantially constant resisting force to displacement of the supported mass at a second threshold load value over a second stage stroking distance, wherein the second threshold load value is higher than the first threshold load value.

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 steering column assembly comprises a first support bracket, a second support bracket, a shroud, and an energy absorbing device. The energy absorbing device comprises a laminated strap having discrete first and second layers, each formed from a separate elongate strip of material that is free to slide over the other strip along a major portion of its length, a portion of the laminated strap being coiled into a spiral, a free end portion of the laminated strap passing through passing through an opening in the second support bracket or the shroud, the free end of a first one of the strips having an opening through which a fastener passes that secures the laminated strap to the first support bracket, and the free end of a second one of the straps being connected to the first strip in a region distal from the free end of the first strip.

A modular shock absorber developed for use in places where shock absorption is required. The modular shock absorber includes; horizontal carriers, a main carrier I and a main carrier II, a central carrier I, a central carrier II, an upper plate I, a lower plate I, a lower plate II, an upper plate II, an upper plate III, a lower plate III, a lower plate IV and an upper plate IV.
