Abstract: 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.

Abstract: A vehicle seat restraint system includes a vehicle seat of a vehicle. The vehicle seat includes a leg-rest supporting lower legs and feet of an occupant of the vehicle seat. An in-vehicle occupant detection system identifies positions of the lower legs and the feet of the occupant. A restraint actuator is connected to the vehicle seat. A safety restraint element is extended by actuation of the restraint actuator from a stowed position proximate to the leg-rest into an engaged position wherein the safety restraint element contacts and restrains the lower legs and the feet of the occupant against the leg-rest, mitigating against occupant knee hyperextension due to leg straightening at an occupant knee joint.
