Description

{STEERING COLUMN FOR VEHICLE}

The present invention relates to a steering column of an automobile, and more particularly, to a steering column of an automobile, more specifically, a tilt lever locking force and a tilt supporting force scattering are reduced at the time of tilting operation so that a tilting operation is smooth, a tilt operation feeling of a driver is improved, To a steering column of an automobile which can prevent a safety problem that an impact from a road surface is transmitted to a steering column or a tilt lever is released when a vehicle collides.

Generally, a steering apparatus of a vehicle can add a telescope or a tilt function to a steering column for the sake of the driver's convenience. The tilt function is a device for adjusting the fixed angle of the steering wheel, and the telescopic device And the two hollow tubes are inserted to allow extension and contraction in the axial direction. Through this function, the driver can adjust the projecting degree or tilt angle of the steering wheel according to his / her elongation or body shape, do.

FIG. 1 is a perspective view showing a conventional automotive steering column. As shown in FIG. 1, a steering column of an automobile according to the prior art includes an inner tube 120 and a relatively slidable inner tube 120 surrounding the steering shaft 103, A mounting bracket 115 for fixing the steering column to the vehicle body, a tilt bracket 109 coupled to the mounting bracket 115, a distance bracket 107 coupled to the tilt bracket 109 and the adjust bolt 101, ).

The steering shaft 103 has an upper end connected to the steering wheel 100 and transmits the rotational force generated by the driver operating the steering wheel 100 to the lower rack-pinion mechanism portion (not shown).

The inner tube 120 is formed in a cylindrical shape and surrounds the lower end of the steering shaft 103. A hinge bracket (not shown) is fixed to the lower end of the inner tube 120 so that a hinge pin (not shown) The steering column is tilted.

A U-shaped tilt bracket 109 is coupled to the mounting bracket 115 and capsules 113 are formed at both ends of the mounting bracket 115 to fix the outer tube 110 to the vehicle body. A tilt hole 109a is formed on the side surface of the tilt lever 105 so that the tilt operation can be performed by operating the tilt lever 105 of the driver.

The distance bracket 107 is coupled to the tilt bracket 109 by an adjuster bolt 101 coupled to the through hole 107a. The distance bracket 107 is welded to the outer tube 110, When the o'clock driver releases the tilt lever 105 for tilt operation, the adjustment bolt 101 is tilted along the tilt elongated hole 109a.

However, in such a conventional automotive steering column, when the tilt operation is performed, the shrinkage displacement of the tilt bracket differs between the upper and lower portions of the tilt bracket, so that the tilt lever locking force and the tilt supporting force scatter are increased, and the tilt operation is not smooth, .

In addition, there is a safety problem in that the tilting support force is not maintained constantly so that the impact from the road surface is transmitted to the steering column, or the tilt lever is released when the vehicle collides, thereby loosening the steering column and injuring the driver.

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing background, and it is an object of the present invention to reduce tilt lever locking force and tilt support force scattering during tilting operation, thereby facilitating tilting operation and improving driver tilting feeling.

Another object of the present invention is to prevent a safety problem of a driver, which is generated when an impact from a road surface is transmitted to a steering column or a tilt lever is released when a vehicle collides, by keeping the tilt support force constant.

Further, the objects of the present invention are not limited thereto, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a mounting bracket for a vehicle, comprising: a mounting bracket having a coupling flange formed by connecting a coupling flange and a coupling flange, And a pair of tilt flanges respectively coupled to the inside of both sides of the connecting flange of the mounting bracket so as to push or release the distance bracket in operation of the distance bracket and the tilt lever.

According to the present invention, when the tilt operation is performed, the tilt lever locking force and the tilt supporting force scatter are reduced, so that the tilt operation is smooth and the tilt operation feeling of the driver is improved.

In addition, according to the present invention, since the tilting support force is maintained constant, there is an effect of preventing the safety problem that the impact from the road surface is transmitted to the steering column or the tilt lever is released when the vehicle collides.
