An occupant protection device includes: a collision prediction unit configured to predict a collision state including a collision direction in a vehicle; a seat direction detection unit configured to detect a direction of a seat that is rotatable around a vertical axis of the vehicle with respect to the vehicle; a driving unit configured to adjust a degree of tension of a seatbelt; and a control unit configured to control the driving unit in accordance with the collision direction with respect to the vehicle predicted by the collision prediction unit and the direction of the seat with respect to the vehicle detected by the seat direction detection unit to change the degree of tension of the seatbelt.

Various systems and methods for implementing an enhanced occupant collision safety system in a vehicle are described herein. A system for controlling deployment of vehicle safety mechanisms of a host vehicle, includes a sensor array interface to receive acceleration data from an impact sensor; an image processor to receive events from an event camera, the event camera configured to monitor a scene of an interior of the host vehicle that includes an occupant; and an occupant safety system controller to: cluster the events to discriminate between events associated with a background of the scene and events associated with a body part of the occupant; detect a collision based on the acceleration data; verify the collision based on the events associated with the background of the scene; and in response to verifying the collision, cause a collision safety mechanism of the host vehicle to deploy.

A restraint system includes a first plate, a second plate rotatably coupled to the first plate and rotatable away from the first plate from an undeployed position to a deployed position, a panel connected to the first plate and to the second plate, and a pyrotechnic activator coupled to the second plate. The panel is flexible relative to the first plate and the second plate. The first plate, the second plate, and the panel form a chamber having an interior volume. The pyrotechnic activator is arranged to, when discharged, rotate the second plate from the undeployed position toward the deployed position. One of the first plate or the second plate includes a vent hole in communication with the interior volume of the chamber.

The present disclosure relates to a method for operating a restraint system having at least one airbag, wherein a head position of a vehicle occupant relative to a reference point in the vehicle is continuously defined. The distance between the head of the vehicle occupant and the at least one airbag in the idle state is determined from the defined head position of the vehicle occupant. The determined distance is evaluated by a comparison with stored reference values and at least one triggering size of the at least one airbag is determined on the basis of the comparison. When the restraint system is triggered, triggering signals corresponding to the at least one triggering size are transmitted to the at least one airbag, as well as to a corresponding restraint system for a vehicle.

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.

An airbag driving apparatus for a vehicle may include: a first acceleration sensor configured to sense acceleration of a vehicle; a collision sensor configured to sense an impact applied to the vehicle; an airbag controller configured to receive a first acceleration value and an impact value from the first acceleration sensor and the collision sensor, determine a collision state of the vehicle, and transmit an ignition command for driving an airbag; and a driving controller comprising a second acceleration sensor installed therein to sense the acceleration of the vehicle, and configured to determine a deployment possibility of the airbag based on a second acceleration value of the second acceleration sensor, receive the ignition command from the airbag controller, and output an airbag deployment signal to the airbag.

A method for triggering at least two safety functions from a predefined plurality of safety functions in a motor vehicle, including a) recognizing a trigger signal for one first safety function, and b) generating a trigger signal for at least one second safety function, if according to step a) the trigger signal for the first safety function has been recognized, the first safety function being of a first function type and at least one of the second safety functions being of a second function type differing from the first function type.

A method to arm an airbag, the method including determining, by a system device, that an arming condition for the airbag has been met; delivering a communication to a master device from the system device to inform the master device that the arming condition has been met; snooping the communication by an expansion device; and arming the airbag by the expansion device in response to snooping the arming condition.

The present description relates to an occupant protecting system for a vehicle, a vehicle comprising such an occupant protecting system and an occupant protecting method for such a vehicle. The occupant protecting system comprises a seat assembly, a sensor unit, an actuator unit and a control unit. The sensor unit is configured to generate crash monitoring data of the vehicle. The control unit is configured to determine a crash type based on the crash monitoring data in case of a collision of the vehicle. The actuator unit comprises a pyrotechnic element. The actuator unit is arranged at the seat assembly and capable to adjust a position of the seat assembly. The control unit is configured to cause the actuator unit based on the crash type.

An apparatus for operating an airbag of an autonomous vehicle may include: an interior image sensor configured to capture an interior image of a vehicle; an input unit configured to receive collision prediction information from an autonomous driving system and the interior image from the interior image sensor; an airbag module installed at the front and side of the interior of the vehicle, and configured to deploy an airbag; and an airbag control unit configured to estimate the sitting position and dynamic behavior of the passenger from the interior image inputted from the input unit, estimate a collision status from the collision prediction information, determine an airbag to be deployed and a time to deploy the airbag according to the sitting position, and then output a deployment signal to the airbag module.
