6.4.1. The design description

In addition to function of management a steering wheel also an element providing safety of the driver.

The power absorbing steering column is designed for reduction травмирования the driver at blow of a body of the driver about a steering wheel.

The switch of ignition and the blocking lock are located on a column, blocking work of ignition and a steering and interfering with car theft.

Switches of a steering column include turn signals, distant and a passing light of headlights, screen wipers and стеклоомыватели.

The note Apply a thin film литиевой greasings on all rubbing surfaces at dismantling and assemblage for maintenance of appropriate work.

The steering column can be disassembled and collected easily.
