Abstract
A multi-frontal airbag for a vehicle and an airbag deployment system using the same are provided. The system includes a sensing unit that collects the state information of a seat. A first airbag module is disposed within the vehicle and includes a first cushion that is deployed toward the front of a passenger and a first inflator that supplies gas to the first cushion. A second airbag module is disposed within a roof above the passenger and includes a second cushion that is deployed downwards and a second inflator that supplies gas to the second cushion. A controller receives the state information of the seat from the sensing unit, and adjusts the operations or operation timings of the first airbag module and the second airbag module.
Claims14
A multi-frontal airbag for a vehicle, comprising:
- a first airbag module disposed within the vehicle and including a first cushion deployed toward the front of a passenger and a first inflator configured to supply gas to the first cushion;
- and
- a second airbag module disposed within a roof above the passenger and including a second cushion deployed downwards and a second inflator configured to supply gas to the second cushion,
- wherein the second cushion includes a main cushion inflated by receiving gas from the second inflator and an auxiliary cushion connected to the front portion of the main cushion to be in communication with each other through a vent aperture and inflated between a front windshield glass and the main cushion upon deployment,
- wherein the second airbag module includes an active vent unit configured to adjust the opening and closing of the vent aperture, and
- wherein the active vent unit includes a closing tether for closing the vent aperture by compressing the edge of the vent aperture and a tether cutter for cutting the closing tether to open the vent aperture when the auxiliary cushion is to be deployed.
A multi-frontal airbag deployment system for a vehicle, comprising:
- a first airbag module unit disposed within the vehicle and including a first cushion deployed toward the front of a passenger and a first inflator configured to supply gas to the first cushion;
- a second airbag module unit disposed within a roof above the passenger and including a second cushion deployed downwards and a second inflator configured to supply gas to the second cushion;
- a third airbag module unit including a third cushion disposed on the upper portion of the second cushion in the roof above the passenger and a third inflator configured to supply gas to the third cushion;
- and
- a controller configured to execute the operations or adjust operation timings of the first airbag module unit and the second airbag module unit,
- wherein the controller is configured to receive state information of a seat, is provided with a data map regarding the state of the seat, and the state of the seat is classified into a front mode and a rear mode based on a degree of sliding of a seat cushion and is classified into a normal mode, a working mode, and a relax mode based on a degree of tilting of a seat back.
