The airbag sensor is a MEMS accelerometer, which is a small integrated circuit with integrated micromechanical elements. The microscopic mechanical element moves in response to rapid deceleration, and this motion causes a change in capacitance, which is detected by the electronics on the chip that then sends a signal to fire the airbag. The most common MEMS accelerometer in use is the ADXL-50 by Analog Devices, but there are other MEMS manufacturers as well. United States Patent #2649311". United States Patent and Trademark Office .

Can I get airbags checked in a normal service?

Airbags are considered "passive" restraints and act as a supplement to "active" restraints. Because no action by a vehicle occupant is required to activate or use the airbag, it is considered a "passive" device. This is in contrast to seat belts, which are considered "active" devices because the vehicle occupant must act to enable them. [4] [5] [6] [7] Quinchía, Alejandra Zapata (10 April 2023).

The auto industry and research and regulatory communities have moved away from their initial view of the airbag as a seat-belt replacement, and the bags are now nominally designated as supplemental restraint systems ( SRS) or supplemental inflatable restraints. In 2019, Honda announced it would introduce a new front passenger airbag technology. Developed by Autoliv and Honda R&D in Ohio, United States, this new airbag design features three inflatable chambers connected across the front by a "noninflatable sail panel." The two outer chambers are larger than the middle chamber. When the airbag deploys, the sail panel cushions the occupant's head from the impact of hitting the airbag, and the three chambers hold the occupant's head in place, like a catcher's mitt. The goal of the tri-chamber airbag is to help "arrest high-speed movement" of the head, thereby reducing the likelihood of concussion injuries in a collision. The first vehicle to come with the tri-chamber airbag installed from the factory was in 2020 (for the 2021 model year) for the Acura TLX. Honda hopes that the new technology will soon make its way to all vehicles. [60] Rear airbag [ edit ] Callas, Tony; Prine, Tom (30 November 2009). "Porsche Airbag Systems". Excellence Magazine. US .

Swedish company Autoliv AB was granted a patent on side-impact airbags, and they were first offered as an option in 1994 [73] on the 1995 Volvo 850, and as standard equipment on all Volvo cars made after 1995.

The Toyota Caldina introduced the first driver-side SRS knee airbag on the Japanese market in 2002. [84] Toyota Avensis became the first vehicle sold in Europe equipped with a driver's knee airbag. [85] [86] The EuroNCAP reported on the 2003 Avensis, "There has been much effort to protect the driver's knees and legs and a knee airbag worked well." [87] Since then certain models have also included front-passenger knee airbags, which deploy near or over the glove compartment in a crash. Knee airbags are designed to reduce leg injury. The knee airbag has become increasingly common since 2000. Jakobsson, Lotta; Lindman, Magdalena; Svanberg, Bo; Carlsson, Henrik (2010).

In vehicles with side airbags, it is dangerous for occupants to lean against the windows, doors, and pillars, or to place objects between themselves and the side of the vehicle. Articles hung from a vehicle's clothes hanger hooks can be hazardous if the vehicle's side-curtain airbags are deployed.

Can I remove airbags myself or switch them off?

Another feature of the Toyota iQ was a seat-cushion airbag in the passenger seat to prevent the pelvis from diving below the lap belt during a frontal impact or submarining. [89] Later Toyota models such as the Yaris added the feature to the driver's seat, as well. In May 1998, Toyota began offering a side-curtain airbag deploying from the roof on the Progrés. [76] In 1998, the Volvo S80 was given roof-mounted curtain airbags to protect both front and rear passengers. [77] Curtain airbags were then made standard equipment on all new Volvo cars from 2000 except for the first-generation C70, which received an enlarged side-torso airbag that also protects the head of front-seat occupants. [73] The second-generation C70 convertible received the world's first door-mounted, side-curtain airbags that deployed upwards. This section needs additional citations for verification.
