Patent number: 6932201Abstract: 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.Type: GrantFiled: June 17, 2003Date of Patent: August 23, 2005Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Hideki Akiyama, Norihiro Kurata

Patent number: 6708803Abstract: An integral self-leveling gas shock strut with dual spring rates as a structural load support between a vehicle chassis and wheel. When the vehicle is driving at an inclined longitudinal pitch a gravity sensitive device within the strut governs a pilot valve which opens to allow a pressure input signal from strut piston compression deflection to close a high flow volume slave valve located between primary and secondary volumetric chambers, trapping gases within the primary chamber to provide a hard spring rate for the strut mounted on the vehicle's downhill side. Contrarily, a similar valve sequence in a companion strut mounted on the vehicle's uphill side opens gas flow communication to combine its primary and secondary chamber volumes, thus providing a soft spring rate and consequent leveling effect of the vehicle using only the pumping action of the strut pistons as a power source, requiring neither external power nor inputs.Type: GrantFiled: June 10, 2002Date of Patent: March 23, 2004Inventor: Mark Andrew Jensen

Patent number: 6682128Abstract: A composite modular energy absorbing assembly with one or more gamma structures 100 that are interposed with one or more delta structures 200. The gamma structures have a base 12′ and a plurality of recesses 16′ defined therewithin. The recesses 16′ have at least one wall 20′ extending from the associated base 12′. At least some of the recesses 16′ are oriented such that their walls are substantially parallel to a major incident component of an impacting force. The walls 20′ collapse. The delta structures 200 have a lattice 210 of interconnected strands which intersect to define a plurality of cells 220. The plane of at least some of these cells are substantially parallel to the impacting force. The lattice collapses during energy absorption. The composite assembly serves to decelerate an object that impacts thereupon in order to maximize energy absorption over a given distance.Type: GrantFiled: June 19, 2001Date of Patent: January 27, 2004Assignee: Oakwood Energy Management, Inc.Inventors: Phillip Patrick Carroll, III, Joel Matthew Cormier, Donald Scott Smith, Richard Francois Audi

Patent number: 6676161Abstract: A linear pretensioning drive for tightening a vehicle seat belt has a guide tube. A piston is located inside of the guide tube and can be driven along a longitudinal axis of the guide tube. A reverse movement lock is formed by balls that are arranged on a ring around the longitudinal axis of the guide tube. In the drive direction in front of the reverse movement lock at least one support part is provided which lies against the inner wall of the guide tube in the locking position with in each case a greater supporting surface than each ball of the reverse movement lock.Type: GrantFiled: May 1, 2002Date of Patent: January 13, 2004Assignee: Breed Automotive Technology, Inc.Inventor: Stefan Schwald

Publication number: 20030183466Abstract: A corrugated ribbon assembly for absorbing energy from an impact. The assembly includes a corrugated ribbon that is embedded in a stabilizing foam. The corrugated ribbon has two sides that define an energy absorbing wall which extends between a first impact edge of the ribbon and a second impact edge of the ribbon. The wall undergoes buckling to absorb energy when the first or second edge is impacted in a direction that is substantially parallel to the wall. The foam provides structural support for the ribbon during buckling thereof.Type: ApplicationFiled: March 29, 2002Publication date: October 2, 2003Inventor: Christopher M. Thayer

Patent number: 6591949Abstract: The present invention is an impact energy absorption member that is characterized by comprising a long member of fiber reinforced resin having a lengthwise direction and a thickness direction, wherein the ratio of the thickness t (mm) of the long member to the length L (mm) thereof is within the range of 1/11000 to 6/1000 as well as the direction of an external force is substantially in agreement with the thickness direction of the impact member. The member of the present invention sufficiently absorbs impact energy from a moving body when collision occurs and greatly increases safety to collision of transportation equipment, for example, a motor car and the like as well as is light in weight and compact, whereby the member can improve resistance against environment and saves energy. Further, when this member is applied to a house and a building against which the transportation equipment may collide, it can reduce the loss of social properties.Type: GrantFiled: October 15, 2001Date of Patent: July 15, 2003Assignee: Toray Industries, Inc.Inventors: Akihiko Kitano, Tomoyuki Shinoda, Hitoshi Nishiyama, Takuya Karaki
