Description

Steering apparatus for vehicles The present invention relates to a steering device for a vehicle, and more specifically, to a steering device for a vehicle capable of adjusting the angle at which a steering axis is tilted. Generally, a vehicle steering system has the function of adjusting the steering shaft, on which the steering wheel is installed, to fit the driver's body. At this time, the function of adjusting the degree to which the steering wheel protrudes is called the telescope function, and the function of adjusting the angle at which the steering wheel is tilted is called the tilt function. These telescopic and tilt functions are achieved by adjusting the degree to which the steering axis protrudes toward the driver and the angle of inclination from the driver. In order for a driver to adjust the degree of protrusion or tilt of the steering shaft, the fixed state of the protrusion and tilt of the steering shaft must be released. To this end, conventional vehicle steering systems were equipped with a lever that protrudes toward the driver. The driver pulled or pushed the lever to release the fixed state of the steering shaft, and then adjusted the tilt of the steering wheel (or steering shaft) to fit their body. However, such conventional vehicle steering systems had a problem in that, in the event of a vehicle accident, the lever would collide with the driver's body (e.g., the driver's knee), causing serious injury. Additionally, the lever occupied space within the vehicle, limiting the driver's usable space, and increased the overall weight of the steering system. Therefore, there has been an urgent need to develop a vehicle steering system that can perform the function of releasing the fixed state of the steering shaft to perform the tilt function, while not causing injury to the driver's body in the event of a vehicle accident and increasing the usability of the driving space.
