Description

[Detailed Description of the Invention] Technical Field The present invention relates to an improvement of a parking brake operating device for a vehicle.

Prior Art By attaching the control lever operated to operate the parking brake to the side of the driver's seat, operability is maintained regardless of the relative movement between the driver's seat and the floor, and the space between it and the passenger seat is saved. It is being ensured. For example, Utsukai Showa 60-66567
This is the parking brake operating device described in the publication.

However, in the conventional parking brake operating device, the cable device for transmitting the operating force of the operating lever to the parking brake requires a relatively large rotation to allow the seat to move in the longitudinal direction. A curved portion is provided. Therefore, the transmission loss of operating force increases due to such a curved part.
Another drawback was that space for the turning section had to be provided on the side of the driver's seat.

Means for Solving the Problems The present invention was developed against the background of the above circumstances, and its gist is to operate the parking brake in a vehicle that has a seat on the floor that can be moved forward and backward. an operating lever that is operated for the purpose of operation, a bracket that rotatably supports the operating lever, a latching mechanism that latches the operating lever in the operating position, and an operating knob that engages and removes the operating lever from the operating position. , the parking brake operating device is of a type in which an operating lever latched by the latching mechanism is latched and unlatched in accordance with the operation of the operating knob, wherein the bracket is fixed to the seat, and the parking brake is fixed to the seat on the floor. The distal end portion is operatively connected to the operating lever in the portion located below, so that the first intermediate lever, which is rotated in conjunction with the operation of the operating lever, and the distal end portion move relative to each other in the direction of movement of the seat. a second intermediate lever that is irreversibly connected to the seat; and a second intermediate lever that is rotatable in a substantially horizontal rotation plane, and an inner cable and an outer cable of a cable device for transmitting operating force to the parking brake. This is because they are attached to the bases of the intermediate lever and the second intermediate lever, respectively.

Operation With this method, the inner cable and outer cable of the cable device are attached to the bases of the first intermediate lever and the second intermediate lever, respectively, and the tips of the first intermediate lever and the second intermediate lever are attached to the seat. Since it is connected to the attached control lever and the seat, the parking brake can be activated by operating the control lever regardless of the seat position.

Effects of the invention Since the inner cable and the outer cable are attached to the bases of the first intermediate lever and the second intermediate lever in this way, the movement of the tips of the inner cable and the outer cable is small relative to the distance that the seat moves. Therefore, it is possible to reduce the number of turns required for these cables. Therefore, the operating force transmission efficiency decreases due to the curved part,
In addition, the space required for the curved portion is greatly reduced.

Further, while the inner cable and the outer cable are attached to the bases of the first intermediate lever and the second intermediate lever, respectively, the tips of the first intermediate lever and the second intermediate lever are connected to the operating lever or the seat. There is an advantage that the operating force transmitted to the parking brake is boosted in accordance with the lever ratio of the lever and the second intermediate lever.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail based on the drawings.

1 and 2, a driver's seat 12 is provided on the floor 10 of the vehicle so as to be movable in the front and rear directions by being guided by rails (not shown), and a driver's seat 12 is provided on the floor 10 of the vehicle so as to be movable in the front and rear directions by a known latching mechanism (not shown). It is designed to be fixed in position. A pair of first
The intermediate lever 14 and the second intermediate lever 16 are connected to the floor 1
It is rotatably provided around a common pin 18 erected at 0. A flexible cable device 20 is led out from the center of the floor 10 in the vehicle width direction onto the floor 10 for transmitting operating force to a parking brake provided on a wheel (not shown). The inner cable 22 and the outer cable 24 are connected to the first intermediate lever 14 and the second
They are each fixed to the base of the intermediate lever 16.

The tip of the first intermediate lever 14 is an operating lever 26
The first intermediate lever 14 is connected to the first intermediate lever 14 via a connecting inner cable 28, and when the operating lever 26 is operated, the first intermediate lever 14 is rotated forward. The operating lever 26 is rotatably supported by a sector 30, a bracket with sector teeth, and a pawl 32 that engages with the sector 30.
and an operation knob 34 for rotating the pole 32. Since the sector 30 is fixed to the side of the driver's seat 12, the operating lever 26 is attached to the driver's seat 12, and operability is ensured regardless of the position of the driver's seat 12. Furthermore, when the operating knob 34 is pressed, the pawl 32 that had been engaged with the sector 30 and latched the operating lever 26 to the operating position is unlatched from the sector 30, and the operating lever 26 is returned to its original position. It's starting to become easier. The sector 30 and pole 32 correspond to a latching mechanism.

The tip of the second intermediate lever 16 is connected to the sector 30 via a connecting outer cable 36, and is connected to the sector 30 in a manner immovable relative to the driver's seat 12 in the front-rear direction.

Therefore, when the operating lever 26 is rotated, the first intermediate lever 14 and the second intermediate lever 1
6 are rotated in a direction toward each other, the inner cable 22 is pulled out from the end of the outer cable 24, and the operating force is thereby transmitted to a parking brake (not shown). Such an operation is performed using the first intermediate lever 14.
The tip of the second intermediate lever 16 is connected to the operating lever 26 and the sector 30 via the flexible inner connecting cable 28 and the outer connecting cable 36, respectively, regardless of the position of the driver's seat 12. It is possible.

Here, when the driver's seat 12 is moved forward, as shown in FIG. 3, while the operating lever 26 and the sector 30 move together with the driver's seat 12,
A first intermediate lever 14 and a second intermediate lever 16 attached to the floor 10 are positioned rearward relative to the driver's seat 12. However, since the inner cable 22 and the outer cable 24 are attached to the base ends of the first intermediate lever 14 and the second intermediate lever 16, they do not move as much as the driver's seat 12 moves. For this reason, the bending part provided in the cable device 20 to allow movement of the driver's seat 12 is reduced to a fraction of the size of the conventional cable, which reduces the efficiency of operating force transmission due to the bending part and The space required for the curved portion is greatly reduced.

Next, another embodiment of the present invention will be described. In addition,
In the following description, parts common to those of the previous embodiment are given the same reference numerals and the description thereof will be omitted.

As shown in FIG. 4, the first intermediate lever 40 and the second intermediate lever 42 are rotatably attached to the floor 10 by pins 18, as in the previous embodiment, and the inner cable of the cable device 20 is 2
2 and an outer cable 24 are connected to their respective proximal ends. The distal end portion of the first intermediate lever 40 is connected to a connecting cable 44 as in the previous embodiment.
The second intermediate lever 4
2 is engaged with an engagement hole 48 formed in a bracket 46 fixed to the driver's seat 12, so that the driver's seat 12 is immovable in the front-back direction.
is connected to.

In this embodiment as well, by operating the operating lever 26, the tips of the first intermediate lever 40 and the second intermediate lever 42 are rotated in the direction of separating them, and the inner cable 22 is moved away from the end of the outer cable 24. drawn out. This causes a parking brake (not shown) to be activated. In addition, the inner cable 22 and the outer cable 2
Since the amount of movement of 4 is reduced to a fraction,
The same effects as in the previous embodiment can be obtained.

Further, as shown in FIG. 5, the cable device 20
The ends of the inner cable 22 and outer cable 24 may be attached to the bases of the first intermediate lever 50 and the second intermediate lever 52 in a direction that is more distant from the operating lever 26 than the pin 18.

Although one embodiment of the present invention has been described below based on the drawings, the present invention can also be applied to other aspects.

For example, the first intermediate lever 14, 40, 5
0 and the second intermediate levers 16, 42, 52 are attached by a common pin 18, but they may be attached by separate pins so as to rotate about different rotation centers.

Further, in the above-described embodiment, the sector 30 to which the operating lever 26 is rotatably attached is attached to the driver's seat 12.
Although it was fixed to the side of the body, there is no problem if it is fixed to the front, etc.

The above-mentioned embodiment is merely one embodiment of the present invention, and various modifications may be made to the present invention without departing from the spirit thereof.
