Nowadays, however, this area contains highly advanced systems such as anti-lock braking system, electronic stability control and collision warning/avoidance through automatic braking. This compares with passive safety (or secondary safety), which are active during an accident. To this category belong seat belts, deformation zones and air-bags, etc.
The cause is classically a head-on motor vehicle collision in which the affected person is wearing only a lap belt. [2] Being hit in the abdomen with an object like a tree or a fall may also result in this fracture pattern. [12] [10] It often involves disruption of all three columns of the vertebral body (anterior, middle, and posterior).
Belts are the cheapest utility for power transmission between shafts that may not be axially aligned. Power transmission is achieved by purposely designed belts and pulleys. The variety of power transmission needs that can be met by a belt-drive transmission system are numerous, and this has led to many variations on the theme.
