Airbag cushion wrapper and related airbag assemblies, along with related assembly/manufacturing methods. In some embodiments, the airbag cushion assembly may comprise an airbag cushion and an inflator comprising an inflator wire. A wrapper may extend about the airbag cushion, which wrapper may comprise a first section wrapped about the airbag cushion in a first direction and a second section coupled with the first section, the second section being wrapped about the airbag cushion in a second direction opposite the first direction and such that the first section extends at least partially within the second section.

An airbag system includes: an airbag deployment device for operating an inflator; and an airbag controller connected to the airbag deployment device by a communication bus and capable of outputting a control signal to the airbag deployment device. The airbag deployment device includes: operation circuits configured to operate the inflator; and an operating power source configured to supply power to a squib included in the inflator. The operating power source is charged by a current flowing through the communication bus.

A safety-related device for use in vehicles, includes a microcomputer, a micro-electronic circuit, a first data bus interface, a second data bus interface, a safety unit (Safety-Agent), a PSI5 sensor link, and a sensor signal simulation unit which can simulate a sensor. The safety unit (Safety-Agent) is controlled via the first data interface by the microcomputer. The sensor signal simulation unit and the sensor interface and the switching between same via the second data interface is controlled via the microcomputer.

A vehicle includes a first battery; a power distribution device configured to provide an IGN power source and a BAT power source from the first battery; a second battery; an airbag; and an airbag control device configured to receive power from the IGN power source of the power distribution device, and to deploy the airbag. The airbag control device may be configured to receive power from the BAT power source of the power distribution device when the vehicle is turned off, and to receive power from the second battery when the battery is damaged.

A squib driver circuit for deployment of a deployable restraint in a vehicle. The safety restraint may have a minimum firing voltage. The voltage regulator may regulate the input voltage to be the minimum firing voltage at the input terminal. The squib driver circuit may be formed on a single chip. The squib driver circuit may include a high side driver and a low side driver. An input terminal for receiving an input voltage used to fire the deployable restraint. The high side driver may supply current from the input terminal to the deployable restraint. The low side driver may supply current from deployable restraint to the electrical ground.

A pre-crash system has at least one dummy actuator and an adaptive pre-trigger function that is implemented with different parameter sets as a function of a current degree of validation, and evaluates the acquired physical quantities for pre-crash recognition in order to recognize an unavoidable crash, a first parameter set, which limits the pre-trigger function to a dummy operating mode in which the pre-trigger function produces at least one trigger signal for the dummy actuator if the evaluation of the physical quantities permits the inference of an unavoidable crash, being implemented until the current degree of validation satisfies a specified condition, the pre-trigger function comparing the triggering of the dummy actuator with the behavior of the evaluation and control unit, and, as a function of the comparison, rating the triggering of the dummy actuator as “correct” or as a “false positive.”
