Vehicle seat provided with a device for protecting the neck in the event of impact from behind
InactiveUS6024406AMitigate such drawbackSafety beltsPedestrian/occupant safety arrangementEngineeringMechanical engineering
A motor vehicle seat has a strength-member for its back that includes an upper portion pivotally mounted on a lower portion and carrying a headrest, the two portions of the strength-member are connected together by a locking device which holds them together and which is dimensioned to give way when the back of a passenger bears against a thrust member of the upper portion of the strength-member in the event of an impact from behind, such that the upper portion of the seat-back strength-member and the upper region of the front face of the seat-back then pivot forwards together with the headrest, with this movement being braked by an energy absorber device.

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.

InactiveUS6321492B1Increase coefficient of frictionNon-rotating vibration suppressionProtective foundationRelative motionEngineering
The invention described is a system for seismic isolation or vibration of structures which is simple, relatively inexpensive and readily used for smaller structures. It involves use of bearings comprising a ball (10) and ball seats (12, 18) interposed between the structure and its foundation. Either the ball itself (24) or the seat surface (15) on which it rolls is compressible, the resistance to that compression providing a frictional braking force resisting rolling of the ball. This serves to dampen relative movement between the structure and its foundation. There are described several alternative constructions of the friction ball which is the preferred central element in the bearing device. There may be a plurality of balls (44, 47) in each combination of balls and seats.

I-Section automotive bumper formed from mineral-filled glass mat thermoplastic (GMT) composite
InactiveUS6286879B1Improve flow characteristicsIncrease modulusBumpersCompression moldingShell molding
The invention is a fiber reinforced thermoplastic automotive bumper wherein the reduced fiber additions consist of a long, chopped glass mat with the addition of mineral fillers such as mica, talc or clay. The modified thermoplastic is used to produce I-section bumpers. The improved reinforced thermoplastic material has favorable flow characteristics which enable the material to substantially fill the deep ribs and mounting stay structures used in I-section bumpers during compression molding while improving the modulus or cross-face stiffness of the finished part. For the first time, improved flow characteristics during molding permit the material to flow evenly into small ribs, bosses and other features. The invention makes it possible to increase part integration, molding pencil braces, fascia supports, mounting holes and mounting stays. The front surface of the bumper may be covered with a conformal energy absorber made of plastic foarn. Moreover, the absorber serves to mount appearance fascia. The result is a cost-reduced, weight-reduced bumper with improved impact resistance.
