A slide piece 120 is interposed between the slide base 110 and the adjustment plate 10 and a fastening bolt 50 for fixing the pillar loop 30 is attached to the slide piece 120. [ (51). A through hole 121 through which the locking pin 140 passes is formed at one side of the slide piece 120.

The slide piece 120 has a guide groove 123 formed by bending both ends of the slide piece 120 so as to be inserted into the guide rail 17 of the adjustment plate 10 and slide.

The slide base 110 has a shape corresponding to the slide piece 120 so as to receive the slide piece 120.

The slide base 110 is formed with a nut hole 111 through which the lock nut 51 passes and a pin hole 113 is formed at one side of the nut hole 111 such that the lock pin 140 passes through the pin hole 113.

The locking pin 140 is formed in a cylindrical shape and passes through the pinhole 113 of the slide base 110 and the through hole 121 of the slide piece 120 and is selectively inserted into the locking hole 15 formed in the adjustment plate 10 .

The locking pin 140 has a cam protrusion 141 protruding from its end. The locking pin 140 is elastically pressed by the locking spring 171 in the direction perpendicular to the plane of the slide base 110 and in the direction toward the adjustment plate 10. [ The locking spring 171 may include a coil spring whose one end is connected to the locking pin 140 and the other end is constrained to the button holder 130.

The button holder 130 includes a holder base 131 coupled to the plane of the slide base 110 and a button guide 133 protruding from both sides of the base holder 131 to guide movement of the button 150, And a button receiving portion 135 connected between the first and second portions 133 and 133 to form a space in which the locking pin 140 is received. The button receiving portion 135 may have a substantially inverted " U " shape. The other end of the locking spring 171 can be contactably supported on the inner surface of the button accommodating portion 135.

The slide base 110, the slide piece 120, and the button holder 130 are integrally coupled through the fastening member 55.

The button 150 includes a guide protrusion 151 that slides along the inner surface of the button guide portion 133 of the button holder 130 and a cam surface that extends inwardly from the guide protrusion 151 and contacts the locking pin 140. [ 153a. The cam surface 153a is formed with an upward slope.

A button spring 173 for elastically pressing the button 150 in a direction away from the button holder 130 is coupled between the button 150 and the button holder 130. The button spring 173 is disposed inside the button receiving portion 135 of the button holder 130 and has one end fixed to the button accommodating portion 135 and the other end fixed to one side of the button 150, . ≪ / RTI >

The button 150 and the button holder 130 may be formed of various suitable materials such as a metallic material and a plastic material.

6 is a partially enlarged and separated perspective view showing a configuration of a button holder and a button according to an embodiment of the present invention.

Referring to FIG. 6, a button groove 137 is formed on the inner surface of the button holder 130 to hold a lubricant. The button groove 137 is formed in a direction substantially orthogonal to the moving direction of the button 150, that is, the upper and lower U.L directions. The button groove 137 is formed to extend from the inner surface of the button receiving portion 135 of the button holder 130 to the button guide portion 133.

The lubricant is supplied while the guide protrusion 151 of the button 150 is slid along the button guide portion 133 so that the movement of the button 150 can be smoothly performed.

The lubricant is also supplied from the button groove 137 to the button spring 173 so that the button spring 173 can be smoothly contracted.

Next, the operation of the seat belt height adjusting device configured as described above will be described.

1 to 4, when the user pushes down the button 150 in the lower direction L to adjust the height of the seat belt 3, the cam protrusion 141 of the locking pin 140 presses the button 140, (I) direction along the cam surface 153a of the cam portion 153 of the cam shaft 150. [

As a result, the locking pin 140 exits the locking hole 11 of the adjustment plate 10 and is released from the locked state.

In this state, when the button 150 is depressed, the slide assembly 100 is moved to a desired position. When the force applied to the button 150 is released, the button 150 is pressed by the button spring 173, .

As the button 150 is lifted, the locking pin 140 moves in the lateral (O) direction along the cam surface 153a of the button 150. When the button 150 rises a certain distance, the hook 150 formed at the end of the button 150 is caught by the cam protrusion 141 of the locking pin 140 and the button 150 stops at a predetermined position.

Since the locking pin 140 is restrained inside the button receiving portion 135 by the locking spring 171 that presses the locking pin 140 toward the adjusting plate 10 side, the pressing force applied to the button 150 is released It is pressed toward the adjustment plate 10 by the restoring force of the locking spring 171 and inserted into the newly selected locking hole 15 to be locked.

The lubricant is supplied from the lubricant groove 19 formed in the plane of the adjustment plate 10 so that the sliding assembly 100 including the locking pin 140 can smoothly move have.

A button groove 137 for holding a lubricant is formed on the inner surface of the button holder 130 for receiving the button 150 so that the lubricant is supplied from the button groove 137 to the button holder 130, It can move smoothly. The button groove 137 is formed to extend from the inner surface of the button receiving portion 135 of the button holder 130 to the button guide portion 133 so that the lubricant is supplied to the button guide portion 133, The guide protrusion 151 formed on both sides of the button guide portion 133 smoothly slides along the button guide portion 133.

Although the present invention has been described with reference to the accompanying drawings and the preferred embodiments described above, the present invention is not limited thereto but is limited by the following claims.

Accordingly, those skilled in the art will appreciate that various modifications and changes may be made thereto without departing from the spirit of the following claims.
