Chinese drivers not wearing seat belts is a common fact that, in this case, the occurrence of a positive impact, the driver will cause a fatal injury.
An "asymmetric" type of airbags can significantly reduce the damage this situation: the use of "asymmetric" mid-size airbags for cars oblique impact test, glue stick the driver of the injured index decreased by 60%. This special bag is currently installed only in Dongfeng Citroen Triumph, etc. have "a fixed set of central control steering wheel," the cars.
Fixed set of control the central feature is the driver steering wheel when the steering wheel only in the rotating ring gear spokes and steering gear,glue gun and the middle of the steering wheel does not rotate. This technique is not as a fixed steering wheel rotation to ensure that the central part of the angle when the cuff, it can install the non-symmetrical airbags to protect the driver. As a result, a protruding upper left, more airbags in the car on a collision can better protect the driver, and this large air bags on those who do not wear seatbelts in the driver's protective effect is particularly prominent.
In addition to install more security "asymmetric" airbags, the steering wheel of the innovative design also loaded with many of the central fixed part of the expansion of previously unimaginable components, thereby allowing the angle of the control interface to obtain an unprecedented breakthrough. Based on this design, many of the necessary auxiliary display device can be easily designed in a more reasonable position, without having to let the driver's vision is of a traditional dashboard, and even had to jump from the road.
This improvement brought the steering wheel steering wheel also is no longer the central cover the following control devices is the original corner and sliding contacts, instead of using the same power supply and other electrical signal transmission cables and wires, which use not only the distribution of current more reasonable, but also reduces the probability of failures and errors occur. Electrical connection between the cable wires can be used instead of the previous contact copper, so this design can be applied to a more powerful electrical equipment. Cable cross-section can be increased in response to demand for automotive electrical engineers, won the ample space.
If you want to back this central fixed set of birth control steering wheel, we must mention Citroen built together with the Swedish Autoliv SCSW R & D program. The expensive program is beginning to consider the future of transportation in the rationality of man-machine interface and scalability, but soon found that this technology may be a landmark security design. The most direct result is in accordance with U.S. NHTSA's FMVSS 208 standards for the 30 ° oblique impact test in this design shown amazing results. In this rigorous testing standards, many new models of crash test failed, because the results under the new aerodynamic design of cars is often more inclined A-pillar has resulted in the test driver's head In this case, oblique collision of the car near the A pillar, individual or even colliding with them, which will cause the driver to escape the reality greatly reduced risk. However, the use of non-symmetric mid-sized car airbag be inclined impact test, the driver of the injury index was reduced by 60% or more. This asymmetry also taken a prominent advantage airbag on the steering wheel has carried on under the protection of outstanding, making the steering wheel on the driver's chest, abdomen, the degree of injury greatly reduced.
At present, this steering wheel has been more and more manufacturers are concerned, the triumph that is installed on a fixed set of central control steering wheel steering wheel will be the future direction of reform.
