Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an extremely simple structure for properly setting a fixed position of a tightening force at an operation angle of an operation lever of a steering device having a tilt mechanism, and saves the entire device. The present invention relates to an operating lever tightening fixed position adjusting device for a steering column capable of realizing a space.

[0002]

2. Description of the Related Art Conventionally, a steering device for adjusting a larger number of tilt and telescopes has been developed. In general, a tilt / telescopic mechanism includes a fastening bolt that is inserted into a movable bracket fixed to a steering column that rotatably supports a handle thereof and a fixed bracket that is attached and fixed to the vehicle body and that clamps the movable bracket. And a stopper member for fixing the rotation direction of the bolt is provided on one side of the fastening bolt.

[0003] On one side, a screw portion for fastening the movable bracket via a fixed bracket is provided. The screw portion of the lever is screwed into the screw portion, and the fixed bracket is clamped and fixed by the fixing bracket with the pressing force generated by the tightening force of the screw due to the rotation of the lever.

[0004]

The fixed bracket and the movable bracket are of a type which can be fixed by the tightening force of a tightening fixing bolt and can be appropriately moved at the time of adjustment. There are types where fixing bolts are used. Each of the fastening bolts is provided with a stopper member for fixing the rotation direction of the fastening bolt. One side of the stopper member is fixed to the movable bracket side, and the other side is fitted (or locked) to the bolt head, and is used for tightening and fixing a lever screwed with a screw portion of the tightening and fixing bolt. It is provided to stabilize operation.

An operating lever is used for locking and releasing when performing a tilt / telescopic operation. When the operating lever is in the initial position, the tightening fixing bolt exerts the most appropriate tightening force. A stopper member is mounted so that the initial position of the operation lever can be adjusted by the stopper member. Such a stopper member is very commonly used in a position adjusting device for a steering column having a normal tilt mechanism.

However, the applicant has filed a Japanese Patent Application No. 10-12.
In the steering column position adjusting device shown in No. 1318, as described above, two tightening fixing bolts are used to extend the range of use of the tilt telescopic. In this type, of course, two stopper members are used.

In addition, the handle adjustment range becomes large, and when the stopper member is simply fixed to the movable bracket and the fastening bolt is fitted and fixed in the same manner as in the prior art, a portion for fixing the stopper member is required. In order to provide the movable bracket and the stopper member outside the handle adjustment range, the entire device is increased in size. Further, a stopper member must be mounted so that the tightening force of the two tightening fixing bolts is constant.

In order to position the arm members to be screwed with the two fastening bolts, the fastening bolts are respectively positioned with respect to the positions of the arm members that are screwed with the thread portions of the fastening bolts. Since the bolts are fastened and fixed, the positions of the bolt heads are arbitrary, and it is extremely difficult to simply fix the rotational directions of the two fastening bolts with a single solid stopper member. There are various disadvantages.

[0009]

Therefore, the first and second stopper members 10 and 11 fitted to the fastening bolts 5 and 5 are engaged with each other, and the support member 12 also moves only in the direction of the vertically long hole 3. Therefore, regardless of the adjustment position of the steering column 16, the direction of expansion and contraction of the return spring 18 can be always substantially fixedly disposed between the fixed bracket 1 and the support member 12.

Therefore, the return spring 18 is movable with respect to the fixed bracket 1 and the movable bracket 2 that moves in the front-rear direction.
As in the case where the return spring 18 is stretched, the return spring 18 is in an inclined state, and the return spring 18 is not stretched more than necessary. In the embodiment shown in FIGS. 4C and 4D, the first and second stopper members 10 and 11 and the support member 12 are connected to the adjusting long holes 10a and 11a by fixing bolts 13. It is fixed by a nut 14.
