A multilayer airbag for a protection system. The multilayer airbag consists of a number of independent airbags within one another which will be inflated with a time sequence or simultaneously.

A control device of an electromagnetic actuator for a restraint device, including an evaluation and control unit which generates a control signal which predefines a control sequence having control time periods, in which the actuator is activated, and pause time periods, in which the actuator is deactivated. A protective circuit including a counter is provided, the counter monitoring the control sequence and increments its counter content during the at least one control time period and decrements its counter content during the at least one pause time period, the protective circuit effectuating a deactivation of the actuator when the counter content reaches or exceeds a predefined first threshold value, and allows a reactivation of the actuator when the counter content reaches or falls below a predefined second threshold value after reaching or exceeding the first threshold value, the first counter content being greater than the second counter content.

An airbag is deployed and inflated by inflating gas discharged from a plurality of gas discharge portions. The airbag is divided into a plurality of inflation chambers. At least one of the inflation chambers is an independent inflation chamber that restricts flow of inflation gas to and from adjacent ones of the inflation chambers. Two or more of the inflation chambers including the independent inflation chamber are discharge inflation chambers, each including the gas discharge portion. The gas discharge portions include a first gas discharge portion that starts discharging the inflation gas at a first timing and a second gas discharge portion that starts discharging the inflation gas at a second timing, which differs from the first timing. The first discharge portion is arranged in at least one of the independent inflation chambers.

Airbag cushion assemblies for aspirating ambient air to enhance inflation. Some embodiments may comprise an inflation module comprising an inflator and a plurality of high-velocity nozzles fluidly coupled with the inflator and configured to deliver inflation gas from the inflator into an airbag cushion. A housing coupled to the airbag cushion, may comprise an aspiration inlet configured to allow for receipt of ambient air into the airbag cushion during inflation of the airbag cushion. The plurality of high-velocity nozzles may be configured to, upon actuation of the inflator, draw ambient air into the airbag cushion along with the inflation gas from the inflator. In some embodiments, a valve assembly may be provided that is configured to open upon actuation of the inflator and to close following inflation of the airbag cushion to prevent air and inflation gas from exiting through the aspiration inlet.

A front air bag for a vehicle is provided. The air bag includes an air bag cushion that has of a plurality of chambers and a gas flow passage that supplies each of the chambers with gas of an inflator. A variable valve selectively closes or opens the gas flow passage. Additionally, a controller determines a type of vehicle collision and operates the variable valve based on the collision type.

A vehicle includes a seat assembly having a seat bottom and a seatback. The vehicle includes a middle console adjacent the seat assembly. The vehicle includes an airbag inflatable from an uninflated position to an inflated position. The airbag is supported by the seatback in the uninflated position and the inflated position. The vehicle includes an inflator supported by the middle console, the inflator operatively connected to the airbag to provide inflation medium.

An inflation device that draws air in from two sources, such as air compressor and ambient air, can inflate an object (e.g., air bag). When a valve is opened, airflow from the air compressor is provided from the inflation device to the object. The airflow may cause airflow from an additional source (e.g., ambient air) into the inflation device. Additionally, a button used to control the valve is also used to initiate power to an assembly that includes pressure sensor (used to measure pressure of the airflow) and a display (used to present the current pressure as measured by the pressure sensor). The inflation device can automatically power down at a predetermined time after the button is released.

An airbag includes a manifold having an outer panel and an inflation chamber defined at least in party by the outer panel. The airbag further includes a first compartment and a second compartment spaced from the first compartment connected to the outer panel and positioned external to the inflation chamber. A first one-way valve is in fluid communication with the manifold and the first compartment, and a second one-way valve is in fluid communication with the manifold and the second compartment.

An airbag includes an inflation side and a vehicle occupant contact side opposite the inflation side, and a divider. The divider has a first portion attached to the inflation side and to the vehicle occupant contact side and a second portion attached to the inflation side and to the vehicle occupant contact side, such that the first and second portions tend to converge from the inflation side toward the occupant contact side.

An air bag packaging arrangement and a self-adhesive checking valve, the air bag packaging arrangement includes an air bag and an air valve which is the self-adhesive checking valve. The air bag includes first and second cell overlapped layers to form an air chamber and a valve opening. The air valve includes first and second sealing films overlapped between the first and second cell layers, and a strengthening film provided between the first valve film and the first cell film to strengthen a joint strength between the first valve film and the first cell film, so as to prevent the first valve film from being broken, so as to further avoid an air leakage.
