Description

Steering column apparatus The present invention relates to a steering column device. Generally, a steering column is a device formed to surround a shaft that transmits rotational force generated by the driver's steering wheel operation to the rack-pinion mechanism, thereby supporting the rotation of the steering wheel while fixing its position by being coupled to the vehicle body. Such steering columns are equipped with a function that absorbs shock by allowing both the steering column and the steering wheel to move axially, in order to prevent the driver's upper body from striking the steering wheel and sustaining serious injuries in the event of a vehicle collision. In other words, when a collision occurs while the vehicle is in operation, the driver's upper body strikes the steering wheel due to inertia; upon impact, the steering column and shaft located at the bottom of the steering wheel contract, thereby reducing the shock received by the driver. However, in conventional steering columns, the lever for fixing or unlocking the steering wheel position is positioned adjacent to the driver's knee, which caused a problem where the lever would impact the driver's knee in the event of a collision. Furthermore, as the impact on the driver's knees increases as the weight of the conventional steering column increases, there is a need for research on steering column structures that can reduce the weight of the steering column.
