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.

In a table device (100) with a tabletop (110), which is coupled to a support strut (120) for mounting on a wall for purposes of a support, a danger of injury to a person located in its vicinity during a sudden acceleration, especially in the direction of travel, is significantly reduced as compared to the known table devices (110) in that the tabletop (110) is fastened to a carrier platform (140) provided with mechanical damping elements (130, 131; 130, 131) and is indirectly connected to the support strut (120) across the mechanical damping elements (130, 131; 130, 131).

Disclosed herein are car seats and bases therefor. The base includes top tether and an energy-absorbing elongate finger. The tether includes webbing. The webbing is at least partially wrapped about the elongate finger. The elongate finger is configured to deform when a load applied thereto by the webbing exceeds a predetermined threshold so as to pay out the webbing from the base.

A supporter includes an upper portion including a load receiver on which a projection projecting downward from a supported body is to be mounted and which receives a load of the supported body. The supporter includes a lower portion to be provided on a floor surface and on which the upper portion is to be mounted. The upper portion includes, in a center portion thereof in a plan view, a first flexure that bends downward under the load of the supported body received by the load receiver. The lower portion includes a second flexure that bends downward when pressed by the first flexure bending downward. In the supporter, a sliding region in which the first flexure being bent downward and the second flexure being bent downward as pressed by the first flexure can slide on each other is defined by the load receiver having received the load of the supported body.

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.

The present invention relates to an shock absorber based on the cutting, inward-folding and crushing of composite tube, comprising a destructing cap, a flat-pressing cap, a cutter and a positioning tube. The cutter is positioned in the destructing cap, and has a lower end connected to an inner flange of the destructing cap and an upper end connected to the positioning tube. The positioning tube is positioned in the destructing cap and closely connected to the inner wall of the destructing cap, and has a lower surface in contact with the cutter. The destructing cap, the positioning tube and the composite tube are respectively provided with aligned pin holes, and bound together with a pin. Energy is absorbed through destruction generated due to cutting and inward-folding of the composition tube. Energy can also be absorbed through destruction generated due to the inward-folding of the composite tube, without using the cutter. Compared to existing technology, the device may be used as a structural component in a normal working state. In the colliding and crushing state, the device fully destructs the composite. The present invention has the following advantages: the energy-absorption ratio is high; and the energy absorbing device only bears an axial force in the process that the composite is being destroyed, does not bend or rupture, keeps the structure stable, and avoids spattering of scraps.

A buckling control assembly for a steering column energy absorption strap assembly is provided. The buckling control assembly includes an inner energy absorption strap operatively coupled to a steering column jacket. Also included is an outer energy absorption strap surrounding at least a portion of the inner energy absorption strap and operatively coupled to the steering column jacket. Further included is a strap constraining structure disposed on a constraint side of the outer energy absorption strap to inhibit buckling of the outer energy absorption strap in a first direction, the outer energy absorption strap having a free side unconstrained to accommodate buckling of the outer energy absorption strap.

An energy absorber comprises a base having a weakened portion, a mounting aperture, and a connecting aperture. An energy absorber assembly includes the energy absorber, an anchor member extending through the connecting aperture, a mounting bracket including an aperture, and a fastener extending through the aperture of the mounting bracket and the mounting aperture of the energy absorber.

A metal pipe has a circular cross section with an outer diameter D and a length not less than 6D. The metal pipe includes a high-strength portion (1A) and low-strength portions (1B). The high-strength portion (1A) is disposed along the entire circumference of the metal pipe to extend a dimension, as measured in the longitudinal direction of the metal pipe, that is not less than ()D and not more than 3D of the metal pipe. The high-strength portion (1A) has a yield strength not less than 500 MPa (or a tensile strength not less than 980 MPa). The low-strength portions (1B) are disposed along the entire circumference of the metal pipe to be arranged in the longitudinal direction of the metal pipe to sandwich the high-strength portion (1A). The low-strength portions (1B) have a yield strength of 60 to 85% of that of the high-strength portion (1A).

A brake assembly comprises a brake plate including a plurality of radially-extending brake tabs, and an extension member extending at least partially through the brake plate. The extension member is movable relative to the brake plate such that the extension member is configured to successively engage the brake tabs. The brake assembly enables one or more forces to be managed or controlled throughout a braking event, such as a fall arrest event.
