摘要:
The present invention provides an energy absorber for a blast barrier system comprising a substantially tubular member extending longitudinally along an axis from a first end portion to a second end portion, each of the first end portion and the second end portion having a substantially similar geometric, profile, wherein the energy absorber collapses under a predetermined load when compressed by a residual blast force. The energy absorber of the present invention may help minimize damage to people and structures by further dissipating force from a blast in a blast barrier system.

An apparatus and method for a composite structural aircraft transmission support link having an integral energy-absorbing feature is disclosed. The link is a two-force member that can carry structural loads up an ultimate load. When loaded beyond ultimate load the design allows sections of the link to fail in a controlled and progressive manner, so that energy is absorbed over a defined stroking distance.
摘要:
A flexible energy absorbing system comprising a material coated, impregnated and/or combined with a strain rate sensitive substance is disclosed. It is formed so as to define repeating adjacent cells, each cell having a re-entrant geometry such that, upon impact, the material locally densifies at the impact site.

A vehicle crush rail includes: a body configured to be at least partially crushed along an axis between first and second ends thereof, the body having a cross section profile that comprises first, second and third cells that are substantially square, wherein at least one of the first, second and third cells extends from the first end to the second end, wherein the first, second and third cells have respective initiators arranged according to a crush pattern for the crush rail.
摘要:
An example apparatus includes (i) a mounting module configured to be coupled to a support frame of a vehicle, (ii) a component-support module configured to support a component of the vehicle, and (iii) a motion-guiding module coupled to the component-support module and the mounting module. The motion-guiding module is configured to guide motion of the component-support module toward the mounting module. The apparatus further includes (iv) a deformable tab coupled to the motion-guiding module. The deformable tab is configured to (a) in response to the deformable tab absorbing a force that is less than a predetermined level, resist motion of the component-support module toward the mounting module and (b) in response to the deformable tab absorbing a force that is greater than the predetermined level, deform to a position that allows the component-support module to move toward the mounting module in response to force applied to the component-support module.
摘要:
An impact diverting mechanism having a top layer and a bottom layer is provided. The two layers are connected such that the top layer is configured to move in relation to the bottom layer when impacted, and therefore is able to divert impact and reduce rotational and linear acceleration on the bottom layer. The impact diverting mechanism may be attached to, or configured to attach to, an object in need of protection, such as a helmet.
摘要:
An apparatus, method, computer program product, and/or system are described that determine an event, actuate a cushioning element in response to the determining the event, the cushioning element including one or more tension-bearing members, and dissipate at least some of an energy associated with a collision based on deforming at least one of the tension-bearing members during the collision, the deforming including substantially inelastically stretching the at least one of the tension-bearing members. Other example embodiments are also provided relating to actuatable cushioning elements.
摘要:
An energy absorbing device for a steering column assembly includes a first end configured to couple to a first component of the steering column assembly and a second end configured to couple to a second component of the steering column. An intermediate portion extends between the first end and the second end. The intermediate portion includes a curved portion having a radius and a leg portion extending between the curved portion and the second end. The leg portion includes a plurality of localized surface features to tune a collapse characteristic of the energy absorbing device and to facilitate maintaining the radius constant when a force moves the first end relative to the second end and deforms the energy absorbing device.

An impact attenuating bladder for lining a helmet shell, the bladder having: a top layer and a bottom layer of fluid impermeable material defining a fluid containment chamber; a fluid outlet in flow communication with the fluid containment chamber; and a fluid release control valve in flow communication with the outlet, the control valve having: a sacrificial elastic membrane with an inside surface in flow communication with the fluid containment chamber and an outside surface, where the outside surface is disposed in an initial configuration when the bladder contains fluid at a minimum initial pressure, and in a rupture configuration when the bladder contains fluid at a maximum rupture pressure; and a membrane rupture device with a membrane engaging tip disposed a predetermined initial distance from the membrane in the initial configuration, and engaging the membrane in the rupture configuration.
摘要:
An anti-vibration clamp for holding pipes includes a pipe holding component which further includes pipe holders for locking the pipes; a clamp body including a stud locking portion for locking to a stud, and a floating attachment portion for holding the pipe holding component; and an elastic connecting component made of soft resin placed between the pipe holding component and the clamp body so that the pipe holding component and the clamp body do not contact one another directly. The pipe holding component, the elastic connecting component and the clamp body are held so that it is difficult for them to each slip mutually.
