## Abstract

The present embodiments provide a steering column for a vehicle, comprising: an upper column having a distance housing on one side of the outer circumferential surface; a telescope fixing member having a plurality of locking grooves formed to be axially apart from one another, and coupled to one side surface of the distance housing; a lower column coupled to the outer circumference of the upper column and having a slit formed at one end in the axial direction, wherein a pair of protruding ends are provided on both sides of the slit, and wherein each adjust bolt is coupled to the protruding end by penetrating therethrough, and a mounting groove is provided at one protruding end; and a telescopic moving member having a locking protrusion formed at a lower end thereof, and which is embedded in the mounting groove.

## Claims

### Claim 1

A vehicle steering column, comprising:
an upper column having a distance housing provided on a side of an outer circumferential surface thereof;
a telescope fixing member having a plurality of locking recesses axially spaced apart from each other and coupled to a side surface of the distance housing;
a lower column fitted over an outer circumference of the upper column, having a slit cut through an outer circumferential surface and inner circumferential surface of an axial side end thereof, having a pair of protruding ends projecting on two opposite sides of the slit while facing each other and penetrated by an adjust bolt, a mounting recess formed to be open in a side surface of one of the protruding ends; and
a telescope moving member having locking protrusions on a lower end to be engaged to the locking recesses and accommodated in the mounting recess,
wherein an elastic member is provided between an upper end of the telescope moving member and an inner surface of the mounting recess to elastically support the telescope moving member toward the telescope fixing member,
wherein a lever cam member is coupled in the mounting recess to support and vertically move the telescope moving member and is penetrated by the adjust bolt to be rotated in conjunction with rotation of an adjust lever.

### Claim 2 (depends on 1)

The vehicle steering column of claim 1, wherein a communication hole for communication with the mounting recess is formed in an upper end of the protruding end with the mounting recess to allow an anti-escape member for preventing escape of the elastic member to be coupled thereinto.

### Claim 3 (depends on 1)

The vehicle steering column of claim 1, wherein a supporting protrusion projects from at least one of two opposite sides of the telescope moving member, and wherein a supporting arm supporting the supporting protrusion extends from a side of the lever cam member.

### Claim 4 (depends on 1)

The vehicle steering column of claim 1, wherein a distance bracket is axially elongated on an outer circumferential surface of the upper column and inserted into the distance housing, and wherein coupling holes are formed in other side surfaces of the distance housing and the distance bracket to allow insertion of rupture bolts.

### Claim 5 (depends on 4)

The vehicle steering column of claim 4, wherein the distance bracket has two opposite side ends bent to leave a space between them and the outer circumferential surface of the upper column to be coupled to the outer circumferential surface of the upper column.

### Claim 6 (depends on 5)

The vehicle steering column of claim 5, further comprising a first bending member having an end supported and fixed by an end of the distance housing and another end bent to surround an end of the distance bracket to be inserted into the space between the outer circumferential surface of the upper column and the distance bracket.

### Claim 7 (depends on 6)

The vehicle steering column of claim 6, wherein a first extension end extends to two sides from an end of the first bending member, and wherein a seating recess is formed in an upper end of an end of the distance housing to allow the first extension end to be coupled and fixed thereto.

### Claim 8 (depends on 7)

The vehicle steering column of claim 7, wherein a fixing protrusion protrudes on the seating recess of the distance housing, and wherein a fixing recess is formed in the first extension end of the first bending member to allow the fixing protrusion to be fitted thereto.

### Claim 9 (depends on 6)

The vehicle steering column of claim 6, further comprising a second bending member having an end supported by an end of the distance housing and another end bent to surround the first bending member to be inserted into a space between the outer circumferential surface of the upper column and the first bending member.

### Claim 10 (depends on 9)

The vehicle steering column of claim 9, wherein a second extension end extends to two sides from an end of the second bending member, wherein a bent end is bent from the second extension end to a side surface of the distance housing, and wherein an actuator is provided to fix or separate the bent end to/from the distance housing.

### Claim 11 (depends on 10)

The vehicle steering column of claim 10, wherein branched ends axially extend from the second extension end, separated bilaterally by an open slit, wherein a receiving recess with a fastening hole is formed in an upper end of the distance housing, and wherein a telescope stopper penetrating the slit is coupled into the fastening hole.

### Claim 12 (depends on 11)

The vehicle steering column of claim 11, wherein a head of the telescope stopper is coupled with a ring-shaped damper.

### Claim 13 (depends on 6)

The vehicle steering column of claim 6, wherein the distance bracket is coupled with a contact member to tightly support and bend the first bending member, at an end in contact with a bending portion of the first bending member.
