Abstract: A method for controlling an inflatable airbag system in a motor vehicle having a seatbelt includes detecting a position of a vehicle occupant relative to an airbag suppression zone (ASZ). Electronic input signals are received from a sensor suite, including an occupant position signal and a seatbelt usage status signal. A restraint capacity setting of the airbag is adjusted in response to the electronic input signals such that corresponding restraint activation logic is executed by the controller based on whether the occupant is belted or unbelted. Different ASZs may be used for belted and unbelted occupants. A motor vehicle includes a vehicle body defining a vehicle interior, an airbag, a seatbelt, a sensor suite for detecting a position of an occupant relative to the ASZ, and a controller operable for controlling a restraint capacity setting and location of the ASZ in accordance with the method.

Abstract: A system according to the present disclosure includes a pawl actuator control module. The pawl actuator control module controls a pawl actuator of a seatbelt retractor to disengage a pawl of the seatbelt retractor from a control disc of the seatbelt retractor. The pawl actuator control module disengages the pawl of the retractor from the control disc when at least one of: a tongue of the seatbelt is disengaged from a seatbelt buckle; a button on the buckle is pressed; a manual disengagement button is pressed; an occupant is present in the seat; and a user provides an instruction to disengage the pawl via a user interface device. The seatbelt retractor allows a seatbelt to be extracted from the seatbelt retractor when the pawl is disengaged from the control disc and prevents the seatbelt from being extracted from the seatbelt retractor when the pawl is engaged with the control disc.

Abstract: A system includes a first webbing payout sensor and a seatbelt wear condition module. The first webbing payout sensor can detect a first webbing payout of a seatbelt associated with a seat of a vehicle. The first webbing payout is a first length of webbing of the seatbelt dispensed from a first retractor of the seatbelt. The seatbelt wear condition module can identify whether the seatbelt is worn correctly based on the first webbing payout. The system may further include a second webbing payout sensor that detects a second webbing payout of the seatbelt associated with the seat. The second webbing payout is a second length of webbing of the seatbelt dispensed from a second retractor of the seatbelt. The seatbelt wear condition module identifies whether the seatbelt is worn correctly based on the first webbing payout and the second webbing payout.

Abstract: A method for controlling an airbag aboard a motor vehicle includes measuring a respective position of landmark points on an occupant of the motor vehicle using a sensor suite. The method includes receiving occupant landmark signals from the sensor suite, with the signals being indicative of the respective positions of the landmark points. A trajectory of the occupant is predicted, via the controller, using the occupant landmark signals. A controller adjusts a restraint capacity setting of the airbag in response to the predicted occupant trajectory. A motor vehicle includes a vehicle body, an airbag, a sensor suite, and a controller operable for controlling a restraint capacity setting of the airbag using the method. A non-transitory computer-readable storage medium includes an instruction set that is executed to perform the method.

Abstract: A method for controlling a passenger restraint system aboard a motor vehicle includes receiving, via a controller, biometric vulnerability classifier signal(s) indicative of vulnerability characteristics of a passenger seated in an interior of the motor vehicle. In response to the biometric vulnerability classifier signal(s) and a detected vehicle event requiring an actuation of the passenger restraint system, the method includes automatically adjusting an actual capacity setting of the passenger restraint system via the controller. A motor vehicle includes a vehicle body defining a vehicle interior, a passenger restraint system positioned in the vehicle interior; and a controller operable for controlling the actual capacity setting of the passenger restraint system in accordance with the method. The passenger restraint system may include a seatbelt, a seat, and one or more airbag systems.
