Abstract
A side airbag system has a side airbag unit, a posture detector, a weight detector, and a deployment controller. The side airbag unit includes an airbag to be deployed with respect to the sideward direction of the occupant sitting on a vehicle seat. The posture detector determines the posture of the occupant. The weight detector measures the weight of the occupant. The deployment controller controls the deployment of the airbag based on the posture checked by the posture detector and weight measured by the weight detector of the occupant.
Claims12
A side airbag system comprising:
- a side airbag unit, which deploys an airbag in a sideward direction with respect to an occupant sitting on a vehicle seat;
- a posture detector, which determines a posture of said occupant;
- a weight detector, which measures a weight of said occupant;
- and
- a deployment controller, which controls the deployment of said airbag based on said posture and weight of said occupant, wherein the posture detector includes a plurality of sensors disposed on a seat back of the vehicle seat, and
- the posture detector monitors a pattern of signal output from the plurality of sensors on the seat back by comparing signal output of each sensor with signal output of the remaining sensors, and estimates the occupant's posture based on a profile of this pattern.

A side airbag system comprising:
- a side airbag unit, which deploys an airbag in a sideward direction with respect to an occupant sitting on a vehicle seat;
- a posture detector, which determines a posture of said occupant;
- a weight detector, which measures a weight of said occupant;
- and
- a deployment controller, which controls the deployment of said airbag based on said posture and weight of said occupant;
- said side airbag unit is provided on one side of a seat back of said vehicle seat, and
- said posture detector includes:
- a plurality of first sensors, which are placed on said seat back and are lined up at regular interval along the up-and-down, direction with respect to said seat back, and
- a second sensor, which is placed on the one side of said seat back, wherein
- said posture detector categorizes said posture of said occupant into one of multiple posture categories based on the detection result of said first sensors and second sensor, and said posture detector outputs a posture information, which indicates said posture category, to said deployment controller,
- said weight detector categorizes said weight of said occupant into one of multiple weight categories, and said weight detector outputs a weight information, which indicates said weight category, to said deployment controller, and
- said deployment controller controls the deployment of said airbag based on said posture information and said weight information.
