A vehicle airbag and restraint system includes a vehicle seat positioned in a vehicle. At least one pressure sensor is included with the vehicle seat to sense when a user is in contact with the vehicle seat. At least one airbag is opened in response to a vehicle crash event. A controller determines when the user is seated on the vehicle seat in a position different than a normally upright position thereby defining the user being out-of-position, and generates a signal applied by the controller to modify an opening sequence of the at least one airbag when the user is out-of-position.

A vehicle event database includes simulation-based vehicle event metadata associated with a vehicle architecture. The metadata is generated by determining vehicle event pulses, applying the vehicle event pulses to a vehicle simulation model, collecting injury data associated with body regions of a simulated occupant within the vehicle simulation model, and predicting a probability of injury to the body regions of an actual occupant of a vehicle having the vehicle architecture based on the injury data. A vehicle event notification is received from a vehicle. Vehicle data and occupant data are received. The simulation-based vehicle event metadata associated with the vehicle architecture of the vehicle is retrieved from the vehicle event database. An injury to a first body region of the body regions of the actual occupant is predicted based on the vehicle data, the occupant data, and the simulation-based vehicle event metadata using an injury prediction model.
