Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a parking brake lever device for a vehicle.

(Prior Art) A parking brake lever device that has a ratchet mechanism and takes an upright position when the brake is applied and a collapsed position when the brake is not applied has been known (see, for example, Japanese Utility Model Application No. 60-45253). .
In order to make it easier for the driver to grasp and operate the parking brake lever, a certain amount of space is left between it and the vehicle body floor when it is in the reclined position, and the lever is maintained in that state. It is customary.

(Problem to be solved by the invention) However, if such a certain space is left, for example, when an occupant passes through the parking brake lever, the occupant is likely to collide with the parking brake lever in the above-mentioned folded position. Since the parking brake lever does not move, there is a problem in that the occupant receives a large shock. Therefore, it is possible to lower the parking brake lever to a position where it lines up with the vehicle floor, but in that case, there will be almost no space between the parking brake lever and the vehicle floor, making it difficult to raise the parking brake lever. There is another problem.

The present invention provides a parking brake for a vehicle that can buffer the collision force that occurs when the parking brake lever collides with the parking brake lever when the parking brake lever is in the reclined position when the brake is not activated, without impairing the operability of the parking brake lever. The purpose is to provide a lever device.

(Means for Solving the Problems) The present invention provides a parking brake lever device for a vehicle in which a parking brake lever is disposed on the floor of the vehicle body and takes a lying position and a lying position, and the parking brake lever assumes a lying position when the brake is not activated. It is assumed that the parking brake lever is attached to either the parking brake lever or the vehicle floor, and when the parking brake lever is in the down position, the parking brake lever is moved further down from the down position on the opposite side from the upright position. The structure includes a resilient member that is elastically supported so as to be movable by a predetermined amount.

(Function) When the parking brake lever is in the collapsed position with the brake not activated, if some force is applied to the parking brake lever, the parking brake lever will resist the elastic force of the elastic member and move further from the collapsed position. Move downwards to the opposite side of the position.
As a result, the influence of the force is buffered by the elastic member. On the other hand, when the action of the force is released, the resilient force of the resilient member returns to the normal laid-down position, and a space for operating the parking brake lever is secured.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In Fig. 1, 1 is a seat of a vehicle such as a car, which includes a seat cushion 2 and a seat back 3.
and a head rest 4, and the seat cushion 2 is rotatably supported on the vehicle body floor 5 via rotation means. Further, a parking brake lever 6 is disposed on the side of the seat cushion 2. This parking brake lever 6 has a reclining position and an upright position, and is of a so-called retractable type, and is in the retracted position when the brake is not applied, but alternatively takes the retracted position or the upright position when the brake is applied.

As shown in FIG. 2, the parking brake lever 6 includes a grip part 6a located at the tip, and a base part 6b connected to the grip part 6a and having a U-shaped cross section and opening downward.
The base portion 6b is rotatably supported by a support member 8 via a pivot shaft 7. The support member 8 is fixed to the vehicle floor 5 and has a side plate 8b having a fixed tooth portion 8a formed at the front portion.

Reference numeral 9 denotes a ratchet lever, which is rotatably supported by the support member 8 about a pivot shaft 10 located behind the pivot shaft 7 of the parking brake lever 6. A movable pawl member 11 whose distal end removably engages with the fixed tooth portion 8a of the support member 8 is rotatably supported on the front portion of the ratchet lever 9, and a proximal end portion of the movable pawl member 11 is rotatably supported. is operation cable 1
2, the movable claw member 11 is connected to an operation button 13 fitted into the tip of the grip part 6a, and when the operation button 13 is pressed, the movable claw member 11 rotates, and its engagement with the fixed tooth part 8a is released. It is becoming more and more common.

14 is a brake cable, the first cable 14
a and a second cable 14b. The first cable 14a has a front end connected to the ratchet lever 9.
The rear end of the brake lever 6 is locked to a fan-shaped member 15 that rotates coaxially with the parking brake lever 6. On the other hand, the second cable 14b has a front end locked to the fan-shaped member 15 and a rear end linked to brake means (not shown). Therefore, the ratchet lever 9 is connected to the brake cable 14 (cable 1
4a, 14b) and a sector-shaped member 15 to brake means.

The parking brake lever 6 is provided with a lifting pin 16, and when the parking brake lever 6 is operated to bring it to the upright position, the ratchet lever 9 is rotated upward via the lifting pin 16, and the brake cable 14 is The brake means is pulled to be in a parked state in which the brake means is activated.

Further, as shown in FIG. 3, the lower end of a coil spring 18 serving as a resilient member is engaged with a mounting member 17 fixed to the support member 8, while the lower end of a coil spring 18 is engaged with a base portion 6b of the parking brake lever 6. Part 19
is installed, and when the parking brake lever 6 is in the lowered position with the brake inactive,
The engaging member 19 engages with the upper end of the coil spring 18, and elastically supports the parking brake lever 6 so that it can be moved a predetermined amount further downward from the down position and opposite to the upright position. .
The engagement member 19 includes an attachment portion 19a fixed to the parking brake lever 6, and an engagement portion 19b which is connected to the attachment portion 19a and projects from the parking brake lever 6 and whose front end is curved downward. Further, the lower end of the coil spring 18 is attached to a mounting tool 20.
It is fixed to the mounting member 17 at.

On the other hand, the rotating means for the seat 1 is constructed as shown in FIGS. 4 and 5. That is, a rotating shaft 22 is erected approximately at the center of the frame 21 of the seat cushion 2, and the rotating shaft 22 is connected to the vehicle body floor 5.
The bearing member 23 is rotatably fitted into a cylindrical bearing member 23 erected therein. In addition, a part of the vehicle body floor 5 protrudes upward to form a protruding part 5a, and the protruding part 5
A lower rail portion 5b is formed on the protruding portion 5a, and an upper rail member 24 is provided on the protruding portion 5a to constitute a rail means. Further, the lower rail portion 5b of the rail means and the upper rail member 2
4 and the support bracket 25 from the frame 21.
is provided protrudingly, and the tip of the support bracket 25 is pivotally mounted.

In addition, 27 is the frame 2 of the seat cushion 2.
This is an engaging portion that protrudes downward from the seat 1, and the rotation operation lever 18 is removably engaged with the engaging portion to disable rotation of the seat 1.

With the above configuration, when the parking brake lever 6 is in the inactive brake state, the movable pawl member 11 is not engaged with the fixed tooth portion 8a, and the brake cable 14 is not pulled. In this state, the engaging member 19 engages with the upper end of the coil spring 18, and the parking brake lever 6 can be moved by a predetermined distance from the collapsed position to the opposite side of the upright position via the coil spring 18. Elastically supported.

Therefore, when a part of the occupant's body collides with the parking brake lever 6 and a force is applied that moves the parking brake lever downward, that force causes the parking brake lever 6 to respond to the elastic force of the coil spring 18. It resists and lies down further below the lodging position (see the two-dot chain line in Fig. 2). Therefore, the shock received by the occupant is cushioned. Moreover, when the above-mentioned force is removed, the parking brake lever 6 is moved by the elastic force of the coil spring 18.
rises up, and assumes a laid-down position in which an operation space large enough to easily grasp the grip portion 6a is secured.
At this time, the movable claw member 11 is located near the lowest part of the fixed tooth portion 8a.

Further, in order to operate the parking brake lever to bring the brake into the operating state, first, the parking brake lever 6 is rotated upward from the down position to the upright position. Then, with the rotation, the ratchet lever 9 is lifted by the lifting pin 16, the brake cable 14 is pulled, and the parking brake is activated. At that time, the movable pawl member 11 provided on the ratchet lever 9 moves to the fixed tooth portion 8a.
Since the latch lever 9 is engaged with the latch lever 9 in a predetermined position, the brake operating state is maintained and the parking state is achieved.

Even when the parking brake lever 6 is rotated downward to the inverted position, the engagement between the movable pawl member 11 and the fixed tooth portion 8a is maintained, so that the parked state is maintained.

In the above embodiment, the front end of the engaging member 19 is curved downward so that the upper end of the coil spring 18 and the engaging member 19 are surely engaged. The front end of the mounting member 17 may be curved upward to prevent the mounting member 17 from falling down, or the entire circumference of the coil spring 18 may be supported instead of curving the front end. Further, while the upper end of the coil spring 18 is fixed to the parking brake lever 6 side, an engaging member as described above is provided on the vehicle floor 5 side (for example, a support member) so that the coil spring 18 moves together with the parking brake lever 6. You can. Further, in the embodiment described above, the lower end of the coil spring 18 is fixed to the support member 8 fixed to the vehicle floor 5, but it may be fixed to the vehicle floor 5 itself, or the coil spring 18 may be fixed to the vehicle floor wall surface. It is also possible to restrict the spring 18 from falling.

Further, although the above embodiment is an example applied to a retractable parking brake lever device, the present invention can also be applied to a normal parking brake lever device as shown in FIG. That is, when the parking brake lever 31 is in the upright position, the movable pawl member 32 is engaged with the fixed tooth portion 33a of the support member 33 in the brake operating state, and when the parking brake lever 31 is in the down position, the movable pawl member 32 is in the supported state. The brake is in a non-operating state when the fixed tooth portion 33a of the member 33 is disengaged, and the parking brake lever 31 is in the lowered position and the brake is not operating.
The upper end of a coil spring 35 whose lower end is locked to the mounting portion 33a of the support member 33 is engaged with the engaging member 34 fixedly attached to the parking brake lever 31, and the parking brake lever 31 can be moved downward by a predetermined amount. is elastically supported.

(Effects of the Invention) As described above, the present invention includes a resilient member that elastically supports the parking brake lever in the retracted position so that it can be moved a predetermined amount further downward from the retracted position on the side opposite to the upright position. Because of this provision, when the parking brake lever is in the collapsed position when the brake is not activated, it is possible to buffer the collision force when the parking brake lever is collided with, for example, when an occupant passes by. The necessary space for operation can also be secured.
