    Abstract: A block of compressible material, such as cellular concrete, provides compressive failure characteristics suitable for arresting travel of an aircraft (or other vehicle) overrunning a runway (or other surface). Relatively thin frangible material positioned above the block provides a stronger, more damage resistant surface, while still readily fracturing in an arresting incident. Intermediate material, such as a foam layer, positioned under the frangible material may be included to provide a protective cushioning effect by mitigating transmission of external phenomena forces to the block. A fastening configuration at least partially enclosing other portions of the arresting unit provides a stable unified composite, without destroying desired compressive failure characteristics of the unit. Arresting units may also include a bottom layer of material stronger than the block of compressible material and a sealant coating with water resistant properties.

    Abstract: A shock absorbing component used as a structural component which realizes a larger energy absorption volume compared to the conventional shock absorbing component is provided. According to the present invention, with regards to the shock absorbing component, a sheet-shaped longitudinal component is formed by placing two or more types of sheet-shaped part materials alternately in the longitudinal direction, and this sheet-shaped longitudinal component is implemented in all of the layers or a part of the layers in the surface component of the shock absorbing component. Therefore, when load due to impact if applied to this shock absorbing component, unlike cases wherein the surface component is formed from a single component, the direction of the load and strain is intricately dispersed by two or more types of sheet-shaped longitudinal components and the concentration of load and deformation is prevented, thereby replacing impact energy with energy which destroys a wide area of the shock absorbing component.

  • Patent number: 6932201
    Abstract: To prevent a shock absorbing material mounted on a vehicle body from collapsing or being scattered under the shock at the time of a collision. The four sides of a shock absorbing material formed of a foamed material are surrounded by a bellows form cover consisting of four corrugated plates inclusive of corrugated plates. Under an external force due to collision, the bellows is folded and contracted easily, but is difficult to be deformed in the width directions. Therefore, the shock absorbing material receives the energy upon collision in its initial shape, so that the energy is absorbed substantially by the compression of the shock absorbing material. Accordingly, it suffices to design a set load for the shock absorbing material by taking into account only the shock absorbing material, so that it is easy to design the shape, material and the like of the shock absorbing material.

  • Patent number: 6206155
    Abstract: The present invention is a dissipating protection energy system designed to receive and safely dissipate the kinetic energy from high energy fragments. The energy dissipation system dissipates energy transferred to it by the incremental and progressive rupturing at an approximately constant force of strategically placed sacrificial stitching applied to a number of high strength straps, such as an aromatic polymide fiber of extremely high tensile strength. Thus, the energy dissipation system provides a lightweight device for controlling and dissipating the dangerous and destructive energy stored in high strength fragments released by catastrophic failures of machinery minimizing damage to other critical components.

  • Patent number: 6109164
    Abstract: A push rod of a vacuum booster includes an inner rod section, a pipe-shaped outer rod section which is slidably fitted over an outer periphery of a rear portion of the inner rod section and connected to a brake pedal, and a buffer member made of a synthetic resin and fitted over the outer periphery of the inner rod section in front of the outer rod section. Usually, an end face of the outer rod section is retained in a position in which it abuts against a projection of the inner rod section. When an axial compressing force is applied to the push rod upon a collision of an automobile, the end face of the outer rod section slides forwards over and past the projection, while buckling the buffer member. Thus, the pushing-up of the brake pedal toward a vehicle compartment due to the retreating movement of a master cylinder is prevented, and the load applied to a driver's foot is alleviated.

  • Patent number: 6086059
    Abstract: A gas spring device is provided with a safe and effective way to reduce to zero the velocity of a piston rod which is traveling at a high velocity in the gas spring device during a failure of the gas spring device. This achieved by stopping the piston rod in a controlled manner through a stepwise reduction in its energy and velocity to keep the force on the piston to a minimum at all times during the failure. The reduction in energy is caused by a plurality of frangible components associated with the gas spring device which are designed to break during a failure, thereby dissipating the kinetic energy of the piston rod.

  • Patent number: 6029536
    Abstract: In a shift lever assembly for a vehicle comprising a base member and a shift lever pivotably supported by the base member, the shift lever is detachable from the base member when an excessive force greater than a prescribed value is applied to the shift lever. Typically, the base member comprises a retaining member for holding the shift lever in an operable position and the retaining member is given a strength so as to break when an excessive force greater than a prescribed value is applied to the retaining member to thereby release the shift lever. In this way, when an excessive force greater than a prescribed value is applied to the shift lever for example by being hit against by a driver or a passenger in a traffic accident, the shift lever is detached from the base and retracted into the instrument panel, thereby effectively preventing the shift lever from causing damage to the driver or passenger.
