Problems solved by technology

However, this will delay the start of the steering column during the secondary collision. On the other hand, in order to advance the start of the steering column during the secondary collision, it is enough to reduce the clamping force of the oblique pivot bolt, but the steering column will be reduced. Support rigidity

Abstract

A steering column device in which a fixation member (7) is attached to a fixation bracket (1) by using bolts (BT, BT), which enables impact force at which a skid bracket (1) starts to slide to be set as desired by adjusting fastening force of the bolts (BT, BT).

Description

technical field [0001] The invention relates to a steering column device capable of absorbing the impact force of a secondary collision. In particular, it relates to a steering column device capable of providing comfortable operability to a driver and improving safety by providing a steering column with two opposing functions of high rigidity and reliable impact energy absorption. Background technique [0002] The steering column device is an important safety guarantee component of the vehicle. In particular, in order to ensure the safety of passengers, how to control the movement of the steering column device in the event of a vehicle collision is extremely important. Usually, the steering column device itself is equipped with an impact energy absorbing mechanism, and an airbag support member housed in the steering wheel also plays an important role. [0003] Currently, various concepts of impact energy absorbing mechanisms exist. Most of them focus on how to absorb the ...
