Description

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

(Prior Art) Conventionally, it has been known that the seat is rotatably provided on the floor of the vehicle body through a rotation means so that the forward-facing seat arranged in the vehicle can be rotated backward. There is.

By the way, a vehicle equipped with such a seat has a ratchet mechanism as described in, for example, Japanese Utility Model Application Publication No. 60-45253, so that the parking brake lever can be moved to a lowered position in a non-parked state and to an upright position in a parked state. If a parking brake lever device that takes
If the seat is rotated in a parked state where the parking brake lever is in the upright position, there is a problem in that it interferes with the parking brake lever. Therefore, in order to eliminate such problems, the applicant has developed a so-called retractable parking brake lever that is placed on the side of the seat cushion of the seat, and that is in a reclined position when not parked, and in a reclined or upright position when parked. A separate application has been filed for a parking brake lever device equipped with.

However, even when a retractable parking brake lever is provided on the side of the seat, there is still a problem that the seat and the parking brake lever will interfere if the user forgets to move the parking brake lever to the reclined position.

(Purpose of the invention) This invention was made in view of the above points, and even when the parking brake lever is in the upright position,
To provide a parking brake lever device for a vehicle that can rotate a seat.

(Structure of the invention) In order to achieve the above-mentioned object, the present invention provides a mechanism for either the parking brake lever or the seat cushion to come into contact with both the seat cushion and the parking brake lever when the seat is rotated. A guide member is provided to push the parking brake lever from an upright position where a portion of the parking brake lever is located above the lower end of the seat cushion to a collapsed position where the entire parking brake lever is located below the lower end of the seat cushion. It is something.

As a result, even if the parking brake lever is in the upright position, when the seat is rotated, both the seat cushion and the parking brake lever come into contact via the guide member, pushing the parking brake lever down to the reclining position. So you can rotate the seat.

(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 headrest 4, and the seat cushion 2 is rotatably supported on the vehicle body floor 5 (see FIGS. 5 and 6) via rotation means.
Further, a parking brake lever 6 is disposed on the side of the seat cushion 2. The parking brake lever 6 has an upright position in which a portion thereof is located above the lower end of the seat cushion 2, and a reclining position in which the entire part is located below the lower end of the seat cushion 2, and when the parking brake lever 6 is not parked. It is a retractable type that can take the lying down position, but can also take the upright position or the lying down position when parking.

As shown in FIGS. 2 and 3, the parking brake lever 6 consists of a grip portion 6a located at the tip, and a base portion 6a that is connected to the grip portion and has a U-shaped cross section and opens downward. is attached via the pivot 7 to a side plate 8 having a fixed tooth portion 8a formed on the front part.
It is rotatably supported by a support member 8 having a shape of b.

Further, a guide member 9 having an inverted V-shaped cross section is fixed to the upper part of the base 6b, and its guide portions 9a and 9b largely protrude laterally (see FIG. 4).

Further, reference numeral 10 denotes a ratchet lever, which is rotatably supported by the support member 8 about a pivot shaft 11 located behind the pivot shaft 7 of the parking brake lever 6. A movable pawl member 12 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 10, and a proximal end portion of the movable pawl member 12 is rotatably supported. is connected via the operation cable 13 to an operation button 14 fitted into the tip of the grip part 6a, and when the operation button 14 is pressed, the movable claw member 12 rotates and engages with the fixed tooth part 8a. is about to be lifted.

15 is a brake cable, the first cable 15
a and a second cable 15b. The front end of the first cable 15a is the ratchet lever 10.
The rear end is locked to a fan-shaped member 16 that rotates coaxially with the parking brake lever 6. On the other hand, the front end of the second cable 15b is locked to the fan-shaped member 16, and the rear end is linked to brake means (not shown). The ratchet lever 10 is therefore linked to the braking means via the brake cable 15 (cables 15a, 15b) and the sector 16.

The parking brake lever 6 is provided with a lifting pin 17, and when the parking brake lever 6 is operated to bring it to the upright position, the ratchet lever 10 is rotated upward via the lifting pin 17, and the brake cable 17 is It is designed to be pulled into a parking position.

On the other hand, the rotating means for the seat 1 is constructed as shown in FIGS. 5 and 6. 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 rotatably fitted into a cylindrical bearing member 23 that is erected on the vehicle floor 5. There is. Further, a part of the vehicle body floor 5 protrudes upward to form a protrusion 5a, a lower rail part 5b is formed on the protrusion 5a, and an upper rail member 24 is provided on the protrusion 5a, forming a rail means. has been done. Also,
A support bracket 25 is provided projecting from the frame 21 between the lower rail portion 5b of the rail means and the upper rail member 24, and a roller 26 that rolls on the lower rail portion 5b is pivotally attached to the tip of the support bracket 25.

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 28 is removably engaged with the engaging portion to disable rotation of the seat 1.

With the above configuration, in order to operate the parking brake to bring the vehicle into the parking 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 10 is lifted by the lifting pin 17, the brake cable 15 is pulled, and the parking brake is activated. At this time, the movable pawl member 12 provided on the ratchet lever 10 engages with the fixed tooth portion 8a and locks the ratchet lever 10 in a predetermined position, so that the brake operating state is maintained and the parking state is achieved (Fig. 3). (see solid line).

Therefore, even if the parking brake lever 6 is rotated downward to the collapsed position, the engagement between the movable pawl member 12 and the fixed tooth portion 8a is maintained, so that the parking brake lever 6 is stored while maintaining the parked state. 3), the seat 1 can be rotated without interfering with the parking brake lever 6.

Also, even if the parking brake lever 6 is not in the reclined position, if the seat 1 is rotated,
Since the seat cushion 2 collides with the guide portion 9a of the guide member 9 of the parking brake lever 6, a pressing force acts on the parking brake lever 6 since the guide portion 9a is downwardly directed outward.
Lower the parking brake lever 6 to the lowered position.

Therefore, whether the parking brake lever 6 is in the upright position or the down position, there is no problem with the rotation of the seat 1 as long as the parking brake is activated and the vehicle is parked.

The above embodiment is an example in which the parking brake lever device is applied to a retractable parking brake lever device. It can also be applied to a normal parking brake lever device that takes a retracted position below the lower end of the brake lever.
Further, in the above embodiment, the guide member 9 is provided on the parking brake lever 6, but it may be provided on the seat cushion.

(Effects of the Invention) As described above, in the present invention, since the guide member is provided, the seat can be rotated without any trouble whether the parking brake lever is in the upright position or in the down position.
