  • Patent number: 8146988
    Abstract: A vehicle seat that strokes during an energy absorption process is able to reset. The seat can therefore stroke again, in the same stroking volume, for example during a secondary ground impact after a mine blast. An energy absorber associated with the seat is operative to absorb energy once during the first stroke and is also operative to absorb energy a second time when the seat strokes a second time.
    Type: Grant

  • Patent number: 6581968
    Abstract: A vehicle safety restraint system for a vehicle that allows transfer of tensile force from a transferor belt to a transferee belt. One end of the transferor belt is secured to the vehicle and the other end is attached to a transferor plate. One end of the transferee belt is secured to the vehicle and the other end is fed through a transferee plate and attached to a tension transfer latch plate. During normal use conditions, the transferee plate and the tension transfer latch plate are united, the transferor plate and the tension transfer latch plate are engaged using a quick release mechanism, and the transferee plate is engaged in a buckle that is secured to the vehicle. When the vehicle experiences a sudden deceleration that exerts a tensile force on the transferor belt, the tension transfer latch plate is separated from the transferee plate if the tensile force exceeds a design value. When the tension transfer latch plate is separated, the tensile force is transferred to the transferee belt.
