DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tilt steering wheel actuation device for an automobile.

In order to improve the ease of getting on and off the vehicle, a tilt steering wheel operating device is already known that moves the steering wheel upward when getting on or off the vehicle. However, as shown in U.S. Patent No. 3,382,944, with conventional devices, the handle swings upward each time the front door on the driver's side is opened or closed. Even when opening and closing the front door, the handle may move upwards against your will.

This invention was devised in view of the above circumstances, and the purpose of this invention is that even when the front door on the driver's seat side is opened and closed, the handle does not move upward each time, and only when necessary. A tilt handle actuating device for moving the handle upward is provided.

In order to achieve the above object, the present invention provides a tilt handle equipped with a tilt spring that moves the handle upward, and the tilt handle is provided with a lock release mechanism that releases the vertical lock state of the tilt handle, and a vehicle speed detecting means and a vehicle speed detecting means are provided. A means for detecting the opening movement of the front door on the seat side is connected to the lock release mechanism, and the lock release mechanism is actuated when the vehicle speed is zero or below a value that can be considered as a stopped state of the vehicle and when the front door is opened. It is characterized by what it did.

A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

3 and the engagement hole 22, and then operate the steering wheel 1 up and down to reach the desired height, and at the same time operate the tilt lever 15 up and down to engage appropriately. The hole 22 and the lock pin 13 are engaged to perform vertical adjustment of the steering wheel 1. In this case, the vertical adjustment is smoothly performed by the click movement between the steel ball 16 and the engagement groove 18.

A support bracket 31 is attached to the right side of the lower tilt bracket 5 so as to face the right end 14a of the push rod 14.

One end of a cable 32 is attached to the support bracket 31, and the end of the cable inner 32b inserted through the cable outer 32a and the push rod right end 14a are connected via a pin 33.

The push rod 14, the support bracket 3
1. A lock release mechanism 34 is constructed which separates the hole plate 21 from the lock pin 13 via the push rod 14 by moving the cable inner 32b to the right using the cable 32 or the like and releases the lock state of the tilt mechanism 24.

A support bracket 45 is provided at an appropriate part of the vehicle body frame 43 near the hinge 42 of the front door 41 on the driver's seat side so that one side 44a faces the front end 41a of the front door 41 when the front door 41 is closed. A bell crank 44 as an engaged member is provided via a support shaft 46, and the other side portion 44b of the bell crank 44 and the cable inner 32b are connected to each other.
Connect to the other end.

As shown in FIG. 5, the front end 41a of the front door 41 has an inclined surface 51 that can freely engage with the one side 44a of the bell crank 44.
A hook 51 as an engaging member having a diameter of 1.a is provided via a support bracket 52 and a support shaft 52a, and is urged by a return spring 53 so that the hook 51 and the bell crank 44 are always engaged.

A solenoid 54 is attached to the bracket 52 as an actuator of the hook 51, an iron core 54a of the solenoid 54 and a rear end 51b of the hook 51 are connected, and the iron core 54a is attracted by energizing the solenoid 54. The hook 51 and the bell crank 44 are disengaged from each other, and the hook 51 is swung via the return spring 53 by cutting off the electricity, so that the hook 51 and the bell crank 44 are engaged.

Next, a vehicle speed detection means 61 such as a speedometer,
Alternatively, a separately provided vehicle speed detection means 61 and the solenoid 54 are connected via a relay 62, so that when the vehicle speed is above a predetermined speed, the solenoid 54 is energized, and when the vehicle speed is below a predetermined speed, the solenoid 54 is de-energized. do.

In the embodiment, the solenoid 54 is energized when the vehicle is moving, that is, when the vehicle speed is high, and the solenoid 54 is de-energized when the vehicle is stopped or can be considered to be stopped, that is, when the vehicle speed is zero or extremely low. .

Since the present invention is configured as described above, when the vehicle is moving, the solenoid 54 is energized and the engagement between the bell crank 44 and the hook 51 is released, and even when the front door 41 is opened or closed while the vehicle is running. , the steering wheel 1 will not move upward against the driver's will.

Therefore, when simply opening the front door 41, for example, when opening the front door 41 and moving it at a slow speed in order to accurately park the car, or when opening the front door 41 and moving it back, the handle is held in the same position. , which is extremely convenient.

Next, to explain the case where the front door 41 is opened and closed while the car is stopped, the current to the solenoid 54 is cut off due to the vehicle speed being zero, and the hook 5 is closed.
1 swings by the elastic force of the return spring 53 and engages with one side 44a of the bell crank 44. Therefore, when the front door 41 is opened when the vehicle speed is zero, the bell crank 44 is swung by the hook 51 that moves integrally with the front door 41 as the front door 41 is opened, and the cable inner 32b is moved to the right. The tilt mechanism 24 is unlocked and the steering wheel 1 is moved upward by the tilt spring 9.

Therefore, when the car is stopped, the driver opens the front door 41.
When the steering wheel 1 is opened, the steering wheel 1 moves upward, and when getting off or getting on the vehicle, the steering wheel 1 is positioned upward, making it extremely convenient to get off and get on the vehicle.

Further, when adjusting the steering wheel 1 up and down by operating the tilt lever 15 and the steering wheel 1, one side 4 of the bell crank 44
Since the steering wheel 4a moves toward the front door 41, the vertical adjustment movement of the steering wheel 1 can be made smoothly as in the past, regardless of the operation of the solenoid 54 corresponding to the vehicle speed.

In the embodiment, the opening movement of the front door 41 is used to operate the lock release mechanism 34, but an appropriate actuator is connected to the lock release mechanism 34, and the vehicle speed detection means 61 and the opening movement of the front door 41 are actuated. A detecting means may be connected to the actuator to operate the lock release mechanism 34 when the vehicle speed is zero or very small that can be considered as a stopped state and when the front door 41 is opened. It may also be operated by negative pressure in the tank.

As is clear from the above explanation, according to the present invention,
The handle can be moved upward only when necessary depending on the vehicle speed, and the device can be operated using the push rod of the tilt mechanism or the opening movement of the front door, so the structure of the device and the structure of various parts can be changed. Can be simplified and compacted,
Furthermore, the handlebar can be adjusted up and down using a tilt lever or the like in the same manner as before, and many other excellent effects are exhibited.
