Patent number: 7566081Abstract: A cushioning clip for receiving a movement of a movable member approaching a stationary member, including a cushioning part, for absorbing an impact force, and a mounting part for mounting the cushioning part to the stationary member. The cushioning part is formed of a flexible material exhibiting elasticity. The mounting part is formed of a rigid material exhibiting a predetermined rigidity. A hollow part is formed in the cushioning part. An inner wall of the hollow part is formed almost perpendicularly to the stationary member, and an apex part on a distal end side of the inner wall is flexed inwardly.Type: GrantFiled: May 16, 2007Date of Patent: July 28, 2009Assignee: Daiwa Kasei Kogyo Kabushiki KaishaInventor: Tetsuya Aoyama

Publication number: 20090167036Abstract: A bumper reinforcement 11 that extends in a vehicle width direction and is removably attached to a vehicle body frame 4 is provided. A vibration damping portion integrally provided with the bumper reinforcement 11 is provided. The vibration damping portion is formed by a hydraulic damper 3 formed into an elongated shape extending in the vehicle width direction and generates damping force with respect to elastic deformation of the bumper reinforcement 11 in the vehicle width direction. Moreover, both ends of the hydraulic damper 3 in the vehicle width direction are fixed to the bumper reinforcement 11.Type: ApplicationFiled: December 26, 2008Publication date: July 2, 2009Applicant: Yamaha Hatsudoki Kabushiki KaishaInventor: Seiji SAWAI

Patent number: 6997490Abstract: An integrated one-piece polymeric molded component includes an energy-absorbing section, a fascia-supporting beam section, and a plurality of connecting section connecting the energy-absorbing and fascia-supporting beam sections. The energy-absorbing section engages a front of a bumper beam and includes crush boxes configured to absorb impact energy during a vehicle crash. The connecting sections are strong enough to hold the energy-absorbing section and the fascia-supporting beam section together during assembly of the one-piece component onto a vehicle, but are flexible to allow collapse of the energy-absorbing section during a vehicle crash without damaging the fascia-supporting beam section. The beam section is channel-shaped and extends cross-car generally between headlamps of the vehicle, for providing added support structure to a front-end of the vehicle. The beam section includes air-redirecting ridges for optimal air flow and integral clips for wire management.Type: GrantFiled: July 21, 2004Date of Patent: February 14, 2006Assignee: NetShape International LLCInventors: Darin Evans, Anthony Jackson

Patent number: 6604765Abstract: An improved bumper system includes a pair of brackets connected to the spaced frame members of a motor vehicle. A support arm is pivotally connected at one end to each of the brackets. The opposite end of each support arm is connected to a transverse beam that forms separate first and second bumper sections. The brackets support the support arms and bumper sections at a desired height above the ground. Each support arm is maintained relative to the respective bracket by gravity. A shear pin provides a redundant retention of the arm relative to the bracket. The arms and bumper sections of the improved bumper system remain in position relative to the bracket even in the event of a horizontal impact. A vertical impact of one or both bumper sections by obstacles or terrain causes the shear pin to be severed, allowing the bumper section(s) to pivot relative to the bracket, rather than to bend or deform.Type: GrantFiled: March 15, 2002Date of Patent: August 12, 2003Assignee: Schwing America, Inc.Inventor: Thomas E. Eull

Patent number: 4974891Abstract: A bumper of a so-called dynamic damper type, which comprises a considerably heavy armature, bushing-mounted holders for connecting the armature to bumper stays of a vehicle body with an interposal of elastic member therebetween, and a bumper facia covering the armature and secured to the vehicle body other than the bumper stays.Type: GrantFiled: March 21, 1990Date of Patent: December 4, 1990Assignee: Nissan Motor Co., Ltd.Inventor: Katsumi Furuta

Patent number: 4770420Abstract: A mounting system for a vehicle-mounted impact absorption box filled with a collapsible open cell network provides a lessened tendency for disintegration when subjected to the vibrations of the vehicle. The system contains a bolt surrounded by a region of transverse cells, with the bolt bonded to the cell walls and passing therethrough in a generally perpendicular direction. A further feature of the system is a pivot bracket constructed in two parts--a rigid portion and a pivot arm, the latter stabilized by springs which absorb torsional impulses on the arm arising from the vehicle vibrations. These two features work in conjunction with each other in reducing shock damage to the interior of the box, and thereby increase the life expectancy of the box as a whole.Type: GrantFiled: January 22, 1987Date of Patent: September 13, 1988Assignee: United Research and Manufacturing, Inc.Inventors: William H. Gottwald, Michel N. Bandak, Thomas N. Bitzer

Patent number: 4573724Abstract: Hardbar bumper assembly is supported by and elastically isolated from the vehicle body by resilient energy absorber so that the bumper functions as a mechanical damper for damping internal vibrations occurring within the vehicle during engine operation including idle. The energy absorber effectively dissipates energy of impact loads including frontal corner and side impacts displacing the bumper from a normal operating position.Type: GrantFiled: November 28, 1983Date of Patent: March 4, 1986Assignee: General Motors CorporationInventor: Lawrence E. Campen

Patent number: 4509781Abstract: A bumper/energy absorber system is resiliently mounted at the body mounting location to allow the bumper/energy absorber system to vibrate freely both vertically and in pitch at its natural frequency. The mounting spring rate is selected to use the dynamic energy of the bumper/energy absorbing system to attenuate steering column vibrations excited through the vehicle body structure by the shaking forces of the engine within a predetermined speed range. The mounting is designed to minimize bumper movement relative to the body from forces directly applied to the bumper from loads such as bumper jacking.Type: GrantFiled: September 20, 1982Date of Patent: April 9, 1985Assignee: General Motors CorporationInventors: Melvin E. Dick, Linn A. Peterson
