DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat lock unlocking device in which a seat lock is unlocked by a key operation.

[0002]

2. Description of the Related Art Generally, in a seat portion of a motorcycle such as a scooter, an upper opening of a helmet storage box is closed with a seat, and the seat is locked with a seat lock. In this configuration, a seat lock unlocking key cylinder is disposed on a cover that covers the periphery of the helmet storage box, and a seat lock is connected to the key cylinder via a wire cable. Has been adopted. The seat lock can be unlocked by operating the key inserted into the seat lock unlocking key cylinder and pulling the wire cable.

In general, a key is used as both a key cylinder for unlocking a seat lock and an ignition key cylinder. Inserting the key into the key cylinder for unlocking the seat lock or into the ignition key cylinder is troublesome. Japanese Patent No. 29137 discloses a seat lock unlocking device that eliminates such troublesome key operations.
Japanese Patent Publication No. 64, “Electric circuit device for motorcycles and the like” (hereinafter referred to as “conventional technology”) is known.

In the above prior art, as shown in FIG. 1 and FIG. 2 of the publication, a mechanism for unlocking a key of a helmet storage box is provided by an ignition switch 15 (the number is cited in the publication. The same shall apply hereinafter.). The ignition switch 15
The "parking position P", "lock position LOCK", "engine stop position O"
FF "," fuel injection position FUEL "," engine operation position ON ", and" helmet storage box unlock position OPE "
N "are arranged in this order clockwise in the figure. By turning the key inserted into the key insertion hole to match the “helmet storage box unlocking position OPEN”, the unlocking solenoid 6 is excited, and the key of the helmet storage box can be unlocked.

[0005]

In FIG. 2 of the above publication, when the motorcycle is stopped and the key is turned to the "engine stop position OFF" to stop the engine and open the helmet storage box, From "engine stop position OFF" to "engine operation position ON"
And then to the “helmet storage box unlock position OPEN”. Therefore, the operation angle for turning the key must be increased. Such an unlocking operation is troublesome and troublesome.

In order to solve this problem, in the above-mentioned conventional technology, a "helmet storage box unlocking position OPEN" is provided between the "lock position LOCK" and the "engine stop position OFF", or the "engine stop position OPEN". OF
It is conceivable that the “helmet storage box unlocking position OPEN” is overlapped with the “F” or the “lock position LOCK”. However, in general, in order to prevent an erroneous operation, a configuration is adopted in which the handle lock mechanism is switched from “engine stop position OFF” to “lock position LOCK” by pushing and turning a key. Therefore, in order to mechanically unlock the key of the helmet storage box in the above-mentioned position, that is, unlock the seat lock, the handle lock and the seat unlock must be realized simultaneously. However, the mechanical structure of the ignition switch 15 becomes extremely complicated, which is not a good idea.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a seat lock unlocking device having a simple structure and improved seat lock unlocking operability.

[0008]

In order to achieve the above object, a first aspect of the present invention is to extend a lock unlocking member from a seat lock for locking a seat, and connect a leading end thereof to a displacement member displaced by a key operation. In a seat lock unlocking device in which a seat lock can be unlocked by a key operation, a displacement member is incorporated in an ignition key cylinder, and the ignition key cylinder opens and closes a seat lock between an off position and an on position of a vehicle power supply. A locking position is provided, and the key is pressed to the seat lock unlocking position, and then the key is pressed, whereby the displacement member is displaced in the seat lock unlocking direction.

The seat lock unlocking position is between an off position for stopping the engine and an on position for starting or enabling the engine. For this reason, the operation angle of turning the key at the time of the seat lock unlocking operation can be small, so that the seat lock unlocking operability is high. Furthermore, the ignition key cylinder has a simple configuration as compared with the case where the seat lock unlocking position is provided between the handle locking position and the off position. The displacement member is displaced in the seat lock unlocking direction when a key corresponding to the seat lock unlock position is pressed. Simply turning the key from the off position to the on position or from the on position to the off position does not cause the displacement member to be displaced in the seat lock unlocking direction. There is no erroneous operation or influence on the normal on / off operation by the key, and sufficient key operability can be secured.

According to a second aspect of the present invention, the ignition key cylinder includes an opening and closing shutter for opening and closing the key insertion hole and a locking mechanism for locking the opening and closing shutter so as not to open. When you do not insert the key into the key insertion hole,
The key insertion hole is closed by the opening and closing shutter, and the opening and closing shutter is locked so as not to open. The effect of preventing mischief and theft is further enhanced.

According to a third aspect of the present invention, the ignition key cylinder is configured so that the key cannot be removed at the unlocked position of the seat lock. To remove the key from the key insertion hole, align the key with a position other than the seat lock unlocking position. After the key is extracted, there is no concern that the displacement member continues to be displaced in the seat lock unlocking direction.

According to a fourth aspect of the present invention, the lock unlocking member is constituted by a cable member, and the cable member is moved downward from an ignition key cylinder disposed at the leg shield portion through a space formed by the front cover and the leg shield. The cable member extends under the step floor to the seat lock, and at least a portion of the cable member passing through the space portion is passed through the tubular cable protector.

Since the lock unlocking member is constituted by a cable member, it is easy to draw the lock unlocking member from the ignition key cylinder to the seat lock. Furthermore, since the cable member passes under the space or the step floor formed by the front cover and the leg shield, it cannot be seen from the outside. Therefore, the anti-mischief can be improved, and the appearance of the vehicle can be improved.
In the front cover part, the cable member passed through the cable protector is further passed through a space formed by the front cover and the leg shield.
Double structure. Therefore, the anti-mischief can be further improved.

Will match the position. Therefore, there is no worry that the displacement member continues to be displaced in the seat lock unlocking direction after the key is removed.

According to the fourth aspect, since the lock unlocking member is constituted by a cable member, it is easy to draw the lock unlocking member from the ignition key cylinder to the seat lock. Therefore, the man-hour for pulling the lock unlocking member can be reduced. Furthermore, since the cable member extended downward from the ignition key cylinder disposed in the leg shield part through the space formed by the front cover and the leg shield, and further extended under the step floor to the seat lock, Can not see the cable member. Therefore, the anti-mischief can be improved, and the appearance of the vehicle can be improved.

According to a fourth aspect of the present invention, the cable member extends downward from the ignition key cylinder disposed at the leg shield portion through a space formed by the front cover and the leg shield, and further extends under the step floor. Since at least the portion of the cable member that passed through the space portion was passed through the tubular cable protector, in the space portion, the cover member (front cover and leg shield) and the cable protector had a double structure. The cable member can be protected. Therefore, the anti-mischief can be further improved.
