Abstract: A passenger identification apparatus for vehicles is provided to identify a passenger through integration of a sensor that senses change in permittivity and a sensor that senses change in pressure. The apparatus includes a permittivity change sensing unit that is installed in the seat and senses change in capacitance generated by permittivity of the passenger seated on the seat and a pressure change sensing unit that is installed in the seat and senses change in pressure generated by a load of the passenger seated on the seat. A controller adjusts power supplied to the permittivity change sensing unit and the pressure change sensing unit and determines whether the passenger is seated on the seat and the type of passenger using permittivity and pressure change values sensed by the permittivity change sensing unit and the pressure change sensing unit.

Abstract: A center curtain airbag for a vehicle may include an upper cushion device configured to be deployed from a roof device of the vehicle into a space between a front seat and a rear seat when an inflator operates; a lower cushion device connecting and communicating with the upper cushion device and configured to extend downwardly from the upper cushion device; and a guide tether including a first end portion coupled to the upper cushion device or the roof device, and a second end portion coupled to a lower end portion of the lower cushion device, the guide tether being configured to provide, when the lower cushion device along with the upper cushion device is deployed, a pulling force to the lower cushion device so that the lower cushion device may be deformed to protrude toward the front and rear seats.

Abstract: An apparatus for classifying a passenger in a vehicle includes a seat cushion for a seat in the vehicle, the seat cushion having an adult detection area and a child detection area. A first chamber is disposed in the adult detection area and a second chamber is disposed in the child detection area. A margin improvement unit includes a pressure sensor configured to measure a first pressure based on a first weight applied to the first chamber and a second pressure based on a second weight applied to the second chamber. The margin improvement unit is configured to output a first adjusted pressure value based on the first pressure and a second adjusted pressure value based on the second pressure. The first adjusted pressure value is greater than the second adjusted pressure value when the first weight is substantially equal to the second weight.

Abstract: A system and method are provided for vehicle passenger classification. The system may include a plurality of weight sensors installed under a seat frame to support a load of a vehicle seat, a single dummy sensor installed under the seat frame to support the load of the vehicle seat along with the plurality of weight sensors, and a passenger classification logic unit for classifying a passenger value obtained by summing sensor values of the plurality of weight sensors as either class 1 or class 2 by comparing the passenger value with a first reference and a second reference.
