Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a steering device for a vehicle, in which a tilted steering column can be appropriately expanded and contracted in an axial direction in order to adjust a front-rear position and a height of a steering wheel according to a physical constitution of a vehicle occupant.

[0002]

[Prior art]

 In a conventional vehicle steering system in which the steering column can be expanded and contracted in the axial direction as appropriate, the key cylinders and column switches mounted on the steering column are also displaced in the axial direction, so the length of harnesses, cables, etc. connected to them is increased. If there is too much room, it may cause the steering column to hang down or break as it contracts.If the room is too small, it may be pulled when the steering column is extended, causing wire breakage. The search was very difficult.

[0003]

[Problems to be solved by the device]

 The present invention is intended to prevent a harness, a cable, and the like arranged along the steering column from hanging even when the steering column in the vehicle steering device is expanded and contracted in the axial direction.

[0004]

[Means for Solving the Problems]

 Therefore, in the steering device according to the present invention, screws are respectively screwed into opposite ends of the shaft that are threaded in the opposite direction, and the rotation of the shaft causes the screws to move toward and away from each other on the shaft. In a steering device capable of axially fixing or expanding and contracting a steering column, a clip portion for covering and supporting a harness and the like is integrally formed with the screw, and when the steering column is fixed, the clip portion fixes the harness and the like. It is configured to restrain.

[0005]

[Action]

 Therefore, if both screws are displaced on the shaft by the rotation of the shaft and the steering column is fixed in the axial direction, the harness etc. covered and supported by the clip part of the screw is also restrained by the clip part at the same time. When both screws are displaced in the opposite directions on the shaft due to reverse rotation of the steering wheel and release the fixation of the steering column, the harness etc. covered and supported by the clip portion of the screw is released from the restraint of the clip portion at the same time. As a result, the harness and other parts can be displaced in accordance with the expansion and contraction of the steering column.

【Example】

 Hereinafter, embodiments of the present invention shown in the drawings will be specifically described. In a vehicle steering system, a column bracket 3 fixed to a steering column 2 is arranged in a gate-shaped bracket 1 fixed to a body side (not shown), and the bracket 1 and the column bracket 3 are respectively provided with a steering column 2. Long shafts 4 and 5 parallel to the axis are formed, and shafts 6 having opposite threads on both ends are inserted through the long holes 4 and 5, and screws 1 and 2 with reverse screws are provided on the left and right sides of the bracket 1, respectively. 8 is screwed.

The screw 8 on the right side has its angular projection 9 fitted in the long hole 4 of the bracket 1 to prevent rotation, while the screw 7 on the left side is as shown in detail in FIGS. 2 and 3. The plate 11 has a structure in which a nut 11 is welded to the outer surface of the plate 10. The bent portion 12 of the plate 10 is fitted into the long hole 4 of the bracket 1 to prevent the screw 7 from rotating and the plate 10 A clip portion 13 having an arcuate cross section is formed at the lower end, and outwardly curved flanges 14 are provided at the front and rear end edges of the clip portion 13. The clip portion 13 covers a harness 15 such as a key cylinder (not shown). There.

Further, a tilt lever 16 is attached to the left end of the shaft 6, and when the shaft 6 is rotated by the rotation of the tilt lever 16, both screws 7, 8 come close to each other on the shaft 6. By sandwiching the bracket 1, the column bracket 3 is pressed to fix the steering column 2, and the clip portion 13 of the screw 7 presses the harness 15 against the side surface of the bracket 1 to restrain the harness 15. .

On the other hand, the shaft 6 is rotated in the opposite direction by the reverse rotation of the tilt lever 16 so that the screws 7 and 8 are separated from each other on the shaft 6, and the pressing of the column bracket 3 by the bracket 1 is released. When the fixation of the steering column 2 is released, the steering column 2 is axially displaced so that it can be expanded and contracted, and as shown in FIG. 4, the screw 7 is separated from the side surface of the bracket 1, and as a result, the side surface of the bracket 1 and the screw are removed. Since the restraint of the harness 15 by the clip portion 13 of 7 is released, the harness 15 can be freely displaced according to the expansion and contraction of the steering column 2.

That is, when the steering column 2 is fixed in the axial direction, the clip portion 13 of the screw 7 can restrain the harness 15 and reliably support the harness 15, and the steering column 2 can be supported in the axial direction. Once the harness 15 is released, the restraint of the harness 15 is released, and the relative displacement of the harness 15 is allowed. Therefore, when the steering column 2 is contracted, the harness 15 can be easily drooped. This can be avoided, and troubles on the wiring can be easily prevented.

Further, in the clip portion 13 of the screw 7, since the outwardly curved flange 14 is provided at the front and rear edges, when the restraint of the harness 15 by the clip portion 13 is released, the harness 15 is Since the harness 15 can be displaced smoothly relative to the clip portion 13 and the harness 15 is not scratched by the clip portion 13, safe wiring and wiring can be performed.

[0012]

EFFECT OF THE INVENTION In the steering device according to the present invention, since the harness and the like are covered and supported by the clip portion provided on the screw of the steering column fixing mechanism, the clip portion is fixed when the steering column is fixed. As a result, the harness and the like are securely supported, and the restraint of the harness and the like by the clip is released when the steering column expands and contracts, and relative displacement of the harness and the like is allowed. The advantage is that troubles on wiring can be easily prevented.
