In addition, there are many parts of the operation cable (outer cable, inner cable, bracket for holding the outer cable, nut for adjusting the length of the inner cable, etc.), and it takes more time to adjust the length of the operation cable. Can be considered.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a seat unlocking lever device capable of simplifying the configuration and easily adjusting the operation feeling.

  The invention according to claim 1 is a seat unlocking lever device that releases the locked state of each of the first locking mechanism and the second locking mechanism provided in the seat, and is coupled to the first locking mechanism, A first operating lever rotatably provided so as to release the locked state of the first lock mechanism by rotating in a first predetermined direction with respect to the first rotation shaft; and the second lock A second operating lever coupled to a mechanism and provided rotatably with respect to the first operating lever via a second rotating shaft provided substantially parallel to the first rotating shaft; And restricting the second operating lever from rotating in the first predetermined direction with respect to the first operating lever, and the second operating lever with respect to the first operating lever. The second direction opposite to the predetermined direction of 1 A restricting / permitting means for allowing rotation in a fixed direction is provided, and the second operating mechanism is locked by rotating the second operating lever in a second predetermined direction with respect to the first operating lever. It is characterized by canceling.

In the invention according to claim 1, the rotation of the second operation lever in the first predetermined direction with respect to the first operation lever is regulated by the regulation / permission means.
That is, it is possible to restrict the rotation of the second operation lever in the first predetermined direction while the first operation lever is stationary.
Thus, when the second operation lever is rotated in the first predetermined direction, the first operation lever can be rotated in the first predetermined direction together with the second operation lever.
The locked state of the first lock mechanism can be released by rotating the first operation lever in the first predetermined direction.

On the other hand, the regulation / permission means allows the second operation lever to rotate in the second predetermined direction with respect to the first operation lever.
Accordingly, the second operation lever can be rotated in the second predetermined direction while the first operation lever is stationary.
By rotating the second operation lever in the second predetermined direction, the lock of the second lock mechanism can be released.

Thus, when releasing the lock of the second lock mechanism, the first operation lever can be held stationary. Therefore, it is not necessary to connect the first operation lever to the first lock mechanism with the operation cable and loosen (bend) the connected operation cable to absorb the movement amount of the first operation lever.
Thereby, a cam mechanism, a link mechanism, etc. can be used as a connection means for connecting the first operating lever to the first lock mechanism.
The connecting means such as the cam mechanism and the link mechanism can reduce the number of parts compared to the operation cable.
Therefore, the configuration of the connecting means can be simplified, and the operation feeling can be easily adjusted.

Alternatively, instead of connecting means such as a cam mechanism or a link mechanism, an operation cable can be used as the connecting means.
Since the first operating lever can be held stationary, it is not necessary to loosen the connected operating cable and absorb the amount of movement of the first operating lever.
Thereby, even when the operation cable is used as the connecting means, the length of the operation cable can be adjusted relatively easily, and the operation feeling can be easily adjusted.

On the other hand, when the amount of movement of the first operation lever is absorbed by loosening the operation cable, it is necessary to adjust the length of the operation cable in consideration of the amount of looseness of the operation cable. Takes time to adjust.
In addition, there are many parts of the operation cable (outer cable, inner cable, bracket for holding the outer cable, nut for adjusting the length of the inner cable, etc.), and it takes more time to adjust the length of the operation cable. Can be considered.

Here, for example, when individual operation levers are provided to release the lock states of the first lock mechanism and the second lock mechanism, it is necessary to provide the operation levers at positions that do not interfere with each other.
Therefore, it is difficult to attach each operation lever at a position where it is easy for the passenger to operate.

For this reason, when the occupant operates each operation lever, it is difficult to operate both operation levers in a posture in which the occupant is seated on the seat (that is, a state in which the occupant's back is in the seat back).
As described above, since the operation lever is operated in a posture different from the posture in which the occupant is seated on the seat (that is, the occupant's back is away from the seat back), it takes time to adjust the seat.

On the other hand, according to the first aspect of the invention, the first lock is obtained by rotating the second operation lever (that is, one operation lever) in the first predetermined direction or the second predetermined direction. Each lock state of the mechanism and the second lock mechanism can be released.
By using one operation lever, it is easy to attach the second operation lever to a position where it can be easily operated by the occupant.

Therefore, when the occupant operates the second operation lever, the second operation lever can be operated in a posture in which the occupant is seated on the seat (that is, a state in which the occupant's back is in the seat back).
As described above, since the second operation lever can be operated while the occupant is seated on the seat, the seat adjustment operation can be quickly performed without taking time.
