An occupant protection method and system, and a computer-readable medium, where the method includes: S1: collecting external environment information of a vehicle; S2: determining, based on the environment information, whether there is an obstacle within a monitoring area, and if yes, proceeding to step S3; or if no, returning to step S1; S3: predicting a movement trajectory of the obstacle; S4: calculating a probability of collision between the vehicle and the obstacle based on vehicle body data and motion information of the vehicle, and the movement trajectory of the obstacle; S5: determining whether the probability of collision is greater than a collision threshold, and if yes, proceeding to step S6; or if no, returning to step S1; S6: partially inflating a seat cushion airbag of the vehicle to adjust a sitting posture of an occupant; S7: determining whether a collision is detected, and if yes, proceeding to step S8; or if no, returning to step S1; and S8: fully inflating the seat cushion airbag.

Aspects of the disclosure relate to reducing the likelihood of injury to a passenger in a collision. In one example, a computing device may determine that an impact between a vehicle and an object external to the vehicle is imminent. The computing device may determine a protection range for a vehicle's airbag based on characteristics of the passenger, including the passenger's seating location within the vehicle. An airbag extension system may position an airbag package, including the vehicle's airbag, such that the vehicle's airbag is within the protection range of the passenger's seating location.

A vehicle airbag control system has an airbag module, a detector and an electronic controller. The airbag module has an airbag that is configured to be positioned below a vehicle floor panel in an undeployed state. The airbag that is configured to be positioned to be above the vehicle floor panel in the deployed state. The detector is configured to detect a presence of an obstruction over the airbag module at a location above the vehicle floor panel. The electronic controller is programmed to deploy the airbag based on a detected result of the detector.

A vehicle occupant protection device includes a seat belt device having a variable force limiter mechanism that can change a force limiter load that an occupant who is sitting on a vehicle seat receives from a seat belt at a time of a frontal collision of a vehicle, an airbag device that deploys an airbag toward the front of the occupant at the time of the frontal collision, a seating position detection unit that detects a seating position at which the occupant is seated, and a control unit that reduces the force limiter load if, compared to a case in which the occupant is positioned within a standard seating region, the seating position of the occupant detected by the seating position detection unit is further toward a vehicle rear than the standard seating region and is within an airbag protection region in which the occupant is protected by the airbag.

A child safety seat is provided and includes a base, a seat body and a notifying system. The seat body is movable relative to the base between a first position and a second position. The notifying system includes at least one actuated device, an actuating component and a notifying device. The at least one actuated device is disposed on one of the base and the seat body. The actuating component is disposed on another one of the base and the seat body and for actuating the at least one actuated device when the seat body reaches at least one of the first position and the second position. The notifying device is electrically connected to the at least one actuated device and configured to generate different types of notifying signals in response to the at least one actuated device when the seat body reaches the first position and the second position.

An occupant protection system for a vehicle may include an expandable curtain and/or an expandable bladder configured to be expanded from a stowed state to a deployed state. The system may also include a transverse ceiling trim panel and one or more side ceiling trim panels configured to be coupled to a ceiling of the vehicle, with the transverse ceiling trim panel extending substantially transversely with respect to the one or more side ceiling trim panels. Portions of the ceiling trim panels may be configured to deflect and allow expansion of the expandable curtain and/or the expandable bladder to the deployed state. The system may also include a deployment controller and one or more inflators configured to cause deployment of the expandable curtain at a first time and deployment of the expandable bladder at a second time after the first time.

Disclosed is a system for controlling a vehicle safety device, the system including: a vehicle safety device configured to protect an occupant; a first occupant detection unit configured to detect a position of the occupant's movable body part; a second occupant detection unit configured to detect a position of the occupant's body part fixed to the safety device; a calculation unit configured to calculate information on the occupant's behavior in the event of a collision accident of a vehicle based on the position of the occupant's movable body part detected by the first occupant detection unit and the position of the occupant's body part fixed to the safety device detected by the second occupant detection unit; and a control unit configured to control an operation of the vehicle safety device for protecting the occupant based on the information on the occupant's behavior calculated by the calculation unit.

An occupant protection device for a vehicle includes a collision predictor, a main airbag, a seat, a sub-airbag, and a deployment controller. The collision predictor is configured to predict a collision of the vehicle. The main airbag is configured to deploy toward an occupant from a front of the vehicle when a collision of the vehicle is predicted by the collision predictor. The seat allows the occupant to be seated, and is movable in a front-back direction of the vehicle. The sub-airbag is accommodated in an upper part of the seat, and configured to deploy downward from above the occupant. The deployment controller is configured to, when a collision of the vehicle is predicted by the collision predictor, cause the sub-airbag to deploy from the upper part of the seat and subsequently cause the main airbag to deploy.

A restraint system includes a seat having a seatback and a seat bottom extending from the seatback in a seat-forward direction. A first airbag is fixed to the seatback at a side of the seat, and a second airbag is fixed to the seat bottom at the side of the seat. The first and second airbags are each inflatable to an inflated position. The second airbag in the inflated position overlaps the first airbag in the inflated position in a seat-rearward direction.
