  • Publication number: 20150001837
    Abstract: An airbag control unit including two, independent trigger control paths that operate sets of first and second switches placed in series with a power source, sets of trigger outputs, and a ground. Each trigger control path is capable of detecting a shock and determining if the shock is a crash-level shock. Each trigger control path outputs a trigger signal to a switch when a crash-level shock is detected and the trigger control path is armed. Current is only supplied to the trigger output if both trigger control paths sense a crash-level shock and are armed. Upon sensing a shock, each trigger control path can power a power hold element that provides temporary power to the trigger control paths long enough to process the shock signals and generate any necessary trigger signals.

  • Patent number: 8903611
    Abstract: A vehicle-occupant protection system in a vehicle has a first sensor and a second sensor on a lateral side closer to a seat of an occupant. The first sensor is either forward of or lateral to the seat of the occupant in the front-rear direction of the vehicle. The second sensor is rearward of the first sensor. The system further includes a collision determination section, which concludes an occurrence of a collision when a signal of the first sensor exceeds a determination threshold value in a situation where a signal of the second sensor has not exceeded a determination threshold value. Upon concluding the occurrence of the collision, the collision determination section activates a movement restraint device to restrain the occupant from moving away from the seat.

  • Patent number: 8714586
    Abstract: A system for protecting an occupant positioned in a seat of a vehicle. The system includes a gas emitting device positioned adjacent to an occupant of a vehicle. The system also may include a controller configured to control the activation of the gas emitting device. A sensor configured to detect the vertical acceleration of the vehicle, may be included. The controller may be configured to receive a signal from the sensor and activate the gas emitting device when the signal from the sensor is indicative of a condition where the vertical acceleration of the vehicle exceeds a predetermined threshold. When activated, the gas emitting device may be configured to emit gas toward the legs of the occupant so that the force of the emitted gas directly forces the legs of the occupant to move.

  • Patent number: 8708366
    Abstract: A safety system for a motor vehicle includes a sensor suite detecting a lateral impact and a vehicle yaw, an occupant safety system, and a control module receiving signals from the sensor suite. The control module activates the occupant safety system if either: a) an impact magnitude detected by the sensor suite is greater than a first impact threshold and a vehicle yaw magnitude detected by the sensor suite is greater than a yaw threshold; or b) the impact magnitude is greater than a second impact threshold higher than the first impact threshold. The system may be operated to determine a longitudinal location of the impact on the vehicle by comparing a magnitude of the impact and a magnitude of the vehicle yaw. The occupant safety system may then be activated in a mode based upon the longitudinal location of the impact and/or appropriate for a spinning vehicle.

  • Patent number: 8684402
    Abstract: An airbag control apparatus of a vehicle includes an occupant determination device, a deployment determination device, a storage device, an airbag controller, and a voltage variation detector. The airbag controller is configured to control deployment of an airbag based on the deployment/non-deployment information. The voltage variation detector is configured to detect a variation in a voltage of an in-vehicle battery and configured to output voltage variation information to the airbag controller. If the voltage variation information indicates that the voltage detected by the voltage variation detector varies, the airbag controller controls the airbag based on deployment/non-deployment information stored in the storage device immediately before the airbag controller receives the voltage variation information indicating that the voltage detected by voltage variation detector varies.

  • Patent number: 8662528
    Abstract: The protective suit is for use by persons engaged in various potentially hazardous activities, but is particularly well adapted for wear by motorcyclists and others engaged in motorsports activities. The suit is equipped with airbags that differ from conventional automotive airbags in that the present airbags deflate more slowly to protect the wearer of the suit over a few seconds in an accident. The suit is also equipped with warning lights that are actuated in the event of an accident. The suit is electronically connected to a belt having various electronic systems capable of monitoring the condition of the motor vehicle and the wearer of the suit through sensors in the vehicle and suit. The suit is further electronically connected to the vehicle, the vehicle having a lockout system that prevents the vehicle from being started until the suit, belt, and helmet are properly connected and operable.

  • Patent number: 8573640
    Abstract: A system and a method for protecting the occupant of a vehicle during a side-impact detects an approaching vehicle and identifies a collision threat. A collision threat level is assessed based on a set of parameters, and when the collision threat exceeds a pre-determined collision threat threshold level, the system unlatches the occupant's door, pushes it a few centimeters outwards, and locks it in that position. Pressure sensors and accelerometers disposed at suitable locations on the sides of the vehicle, provide crash signals to a Restraint Control Module (RCM). When the crash signals exceed a certain threshold, the RCM commands an airbag deployment module to deploy the airbag between the occupant and the door. Since the door is pushed outwards, an extra pre-crush space is created between the occupant and the door, which allows the use of larger and softer side airbags to provide enhanced protection to the vehicle occupants.
