The tilt type steering device described in this publication is
As shown in FIG. 12, the so-called neck-off type is used. In order to insert the steering shaft 1, the cylindrical steering column 2 is divided into a lower column 3 and an upper column 4, The steering columns 3 and 4 are connected to each other by a support bracket 5 portion mounted on the vehicle body, and the upper column 4 therein is provided with a horizontal shaft 6 provided on the support bracket 5 as shown in FIGS. , 6 can be swung freely.

Between the support bracket 5 and the upper column 4, there is provided a locking mechanism that can be engaged and disengaged by a tilt lever 7 that swings about the horizontal shafts 6, 6, and the upper column 4 is connected to the support bracket 5. Do (upper column 4
Of the upper column 4 can be displaceable with respect to the support bracket 5 (the upper column 4 can be swung).

That is, one end of the upper column 4 is pivotally supported on the support bracket 5 by the horizontal shafts 6, 6 provided on the support bracket 5 fixed to the vehicle body on the lower surface of the dashboard 8 or the like, and The first engagement member 9 is fixed to the lower surface. The lower surface of the first engaging member 9 forms an arcuate convex surface with the horizontal axes 6, 6 as the center, and the first engaging teeth 10 are formed on this lower surface.

On the other hand, another horizontal shaft 11 provided on the support bracket 5 has one end of a second engagement member 12 which is engaged with and disengaged from the first engagement member 9 as the tilt lever 7 swings. (Thirteenth,
The left end of Figure 15) is pivotally supported. At the upper edge of the other end of the second engaging member 12 (upper edge of the right end in FIG. 13), the first engaging tooth 10 formed on the lower surface of the first engaging member 9 is disengaged. A free, second engagement tooth 13 is formed.

Further, a roller 15 is supported on a shaft 14 which is provided so as to be bridged between the lower ends of the tilt levers 7 whose intermediate portions are pivotally supported by the horizontal shafts 6, 6, and the upper surface of the roller 15 is supported. , Is brought into contact with the lower surface of the second engaging member 12.

Furthermore, a pin 18 protruding from the side surface of the second engaging member 12 is engaged with an inclined elongated hole 17 formed in a swing plate 16 fixed to the tilt lever 7.

Since the tilt lever 7 is configured as described above,
When the roller 15 is swung counterclockwise in the figure, the roller 15 retreats from below the other end (the right end in FIG. 13) of the second engaging member 12, and at the same time, the engagement between the inclined elongated hole 17 and the pin 18 is increased. Based on the combination, the other end of the second engaging member 12 is displaced downward.

As a result, the second engaging teeth 13 formed on the upper surface of the other end of the second engaging member 12 and the second engaging teeth 13 formed on the lower surface of the first engaging member 9 fixed to the lower surface of the upper column 4. One engaging tooth 10
Is disengaged, and the upper column 4 is moved to the horizontal shafts 6 and 6 (within a range in which the pin 19 projecting from the side surface of the upper column 4 can be displaced inside the arcuate elongated hole 20 formed in the support bracket 5). It becomes possible to swing around the center of the upper column 4, and the height position of the steering wheel fixed to the end of the steering shaft 1 inserted through the inside of the upper column 4 can be adjusted freely.

When the height position of the steering wheel is adjusted in this manner, the tilt lever 7 is swung in the clockwise direction in FIG. The second engaging teeth 13 formed on the upper edge of the other end of the second engaging member 12 are pushed up and pushed up.
And the first engaging teeth 10 formed on the lower surface of the first engaging member 9 fixed to the lower surface of the upper column 4 are engaged, and the upper column 4 does not rotate about the horizontal shafts 6, 6. Like

As a result, the steering wheel is kept in the height-adjusted position. In this state, the tension spring 21 gives the tilt lever 7 an elastic force to swing clockwise in FIG.
The 15 does not inadvertently retract from the lower side of the second engaging member 12.

In the case of the structure of the first example, the first engaging member 9 is fixed to the lower surface of the upper column 4, and the second engaging member 12 is pivotally supported on the support bracket 5. On the contrary, as shown in FIG. 16, there is also a structure in which the first engaging member 9 is fixed to the lower surface of the support bracket 5 and the second engaging member 12 is pivotally supported on the upper column 4.

Further, in FIG. 13 and FIG. 16, 22 is a tension spring, and this tension spring 22 causes the upper column 4 to move when the engagement between the first and second engaging teeth 10 and 13 is released. It has a role of swinging in the counterclockwise direction in each figure about the horizontal shafts 6, 6 to displace the steering wheel 23 (Fig. 12) fixed to the upper end of the steering shaft 1 to the uppermost position.

(Problems to be Solved by the Invention) However, in the case of the conventional tilt type steering device used as described above, there are the following problems to be solved.

That is, in the case of the conventional tilt type steering device, when the driver's knee hits the tilt lever 7 in response to an impact accompanying a collision accident, the first and second engagement teeth are
When the engagement between 10 and 13 is disengaged, the elasticity of the tension spring 22 causes the steer rig wheel 23 to rise to the uppermost position.

When a car has a collision accident, a so-called secondary collision occurs in which an automobile or other occupant collides with a steering wheel, a dashboard, or the like, following a so-called primary collision in which the automobile collides with another car or the like. In order to reduce the injury to the driver at the time of the secondary collision, it is preferable that the height position of the steering wheel 23 is kept low.

That is, when the steering wheel 23 is at a high position, especially when the driver is small, at the time of the secondary collision,
The steering wheel 23 and the driver's head are likely to collide with each other, resulting in serious injury.

In addition, since the so-called airbag, which protects the driver by inflating the balloon during a collision, is built in the center of the steering wheel, the knees of the driver may hit the tilt lever due to the impact of the primary collision. If the steering wheel jumps up, there is a possibility that the driver cannot be sufficiently protected due to the secondary collision even if the airbag operates.

In particular, in the case of a so-called tilt-type steering device with a flip-up mechanism, in which the steering wheel is raised beyond the tilt adjustment range so that the driver can easily get on and off, the above-mentioned amount of the steering wheel is large, Such inconvenience becomes remarkable.

The tilt type steering device of the present invention prevents the steering wheel from rising in the event of a collision accident.
This is to solve the above-mentioned inconvenience.

(Means for Solving the Problems) In each of the tilt type steering devices of the present invention, a support bracket fixed to the vehicle body, an upper column whose one end is pivotally supported by the support bracket by a horizontal shaft, and this upper column Alternatively, a first engaging portion provided on a part of a member supported by the upper column, and a second engaging portion provided on a part of the supporting bracket or a member supported by the supporting bracket. , And a tilt lever that engages and disengages the first engaging portion and the second engaging portion with rocking.

Further, in the tilt type steering device of the present invention, according to claim 1, there is provided a fixed bracket which is partially fixed to the support bracket, and the fixed bracket. By fixing one end to the part fixed to the upper column and the other end to the part fixed to the upper column, and displacing the upper column to the uppermost position, the part fixed to the fixing bracket and the upper column are fixed. A portion having a flexible tension member having a length enough to be tensioned between the flexible tension member and a portion of the displacement side hook portion that is engageable with the fixed side hook portion. And a displacement bracket which has a pressing portion and is locked to the fixed bracket so as to be pivotable and slightly displaceable, and is displaced axially toward the upper column when a strong force is applied. Roaco The one end to a fixed part arm, the other end portion of the displacement bracket, and a pressure rod coupled respectively.

Then, as the pressing rod presses a part of the displacement bracket based on the displacement of the lower column,
While engaging the fixed side hook portion and the displacement side hook portion, the pressing portion presses the intermediate portion of the flexible tension member in a direction perpendicular to the length direction of the flexible tension member. The flexible tension member is tensioned regardless of the position of the upper column.

Further, in the tilt type steering device according to claim 2, a long hole formed in a part of the support bracket in the front-rear direction, a slider displaceable along the long hole, and the upper portion. An extension part provided in a portion of the column facing a position near one end of the elongated hole, a spring having elasticity for moving the slider toward the one end of the elongated hole, and one end Is attached to the slider, and the lower column, which is displaced in the axial direction toward the upper column when a strong force is applied to the other end, is connected to the slider.

Then, as the pulling cable pulls the slider on the basis of the displacement of the lower column, the elastic force of the spring causes the slider to move to one end of the elongated hole. It is characterized in that it can freely collide with the extension.

(Operation) In the case of the tilt type steering device of the present invention configured as described above, the operation is performed as described below to prevent the steering wheel from rising in the event of a collision.

First, in the case of the tilt type steering device according to claim 1, when the lower column is displaced toward the upper column due to a collision, the pressing rod presses a part of the displacement bracket based on this displacement, The fixed side hook portion provided on the support bracket and the displacement side hook portion provided on the displacement bracket engage with each other, and the displacement bracket is fixed to the support bracket.

In this way, in the process of engaging the fixed side hook portion and the displacement side hook portion, the pressing portion provided on the displacement bracket moves the middle portion of the flexible tension member to the flexible tension member. As a result of pressing in the direction perpendicular to the length direction to tension the flexible tension member, the upper column does not swing in the direction of raising the steering wheel.

Further, in the tilt type steering device according to the second aspect, when the lower column is displaced toward the upper column due to a collision, the force of the pulling cable pulling the slider based on this displacement is released, and the spring is released. The elastic force moves the slider to one end of the long hole. As a result, the slider and the extension formed on the upper column can collide with each other, and the upper column does not swing in the direction of raising the steering wheel.
