PATEV Associates have today announced the start of the innovation program "better Airbags"
The fundemental technology behind airbags has changed little over the last 30 years. The MBB International Group AG has developed and patended this new technology that uses a high-speed valve instead or pyrotechnics to control the outflow of the air into the bag. Designed to take the airbag to the next level.
The airflow can be adapted to the passenger load and even activated more than once in the case of a multi-impact crash.
Drivers would run a lower risk of injury or aural trauma after an airbag explosion and suffer no carbon monoxide pollution in the vehicle interior. The airbag is adapted to to the real time passenger load and accident type.
This is a very interesting article by moditech.com and something we need to be ready for.
Gull-wing doors are doors on a vehicle that open upwards, a portion of the roof opens together with the door. Scissor doors are hinged on the A-post and also open in an upward motion, in both cases the opening process is normally supported by pressurized cylinders so that that the door does not close under its own weight.
Should the vehicle be involved in a collision and come to rest on its roof, opening the Gull-wing or scissor doors will not be possible in most cases. So the vehicle manufacturers have come up with a special solution on the late model vehicles Mercedes Benz SLS AMG and Lamborghini Aventador.
Should the vehicle come to rest on its roof, the control unit for the SRS detects the vehicle position and activates pyrotechnic charges on the door hinges. In the case of the Mercedes SLS AMG all four door hinges are equipped with such a pyrotechnic charge which disconnects the hinge arm from the door. The pyrotechnic charge does not directly sever the hinge arm but activates a mechanism that mechanically disconnects the door and hinge arm.
For emergency responders this means that after opening the lock the door may be horizontally pulled off the hinge arms from under the vehicle, this is why it is essential to try the lock first. If this doesn't work, the door locks can be opened with hydraulic tools. In the case of the SLS AMG the lock is located on the front side of the door where the A-post and the rocker panel connect. To completely remove the door it is necessary to untie or cut the rod of the door support cylinders.
