Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement in a locking device for a car seat.

(Prior Art) Conventionally, the seat back is locked to the vehicle body by a locking mechanism in an upright state with the front side of the trunk area closed, and by releasing the lock of the locking mechanism, the seat back can be tilted forward to open the front side of the trunk area. A locking device for a car seat has been proposed.

The above-mentioned lock device is designed to unlock or lock the lock mechanism by manually pulling up or pushing down a lock knob protruding from the top of the seat bag.

Therefore, since the lock can be released without a key while the vehicle is parked, there is a problem in that it is not safe to store luggage in the trunk space that is blocked by the seat bag.

(Purpose of the invention) The purpose of the invention is to improve the storage safety of luggage in the trunk room.

(Structure of the invention) Therefore, in the above-mentioned type of automobile seat lock device, the present invention is provided with a solenoid that locks the lock knob inoperably in the lock mechanism, and which locks the lock knob into an ignition key cylinder of the engine. The present invention is characterized in that a control circuit is provided that operates the solenoid to the non-latching position only when the ignition key is inserted.

(Effects of the invention) According to the invention, when the ignition key is not inserted into the key cylinder of the engine, the solenoid is activated to the locking position, so when the ignition key is removed when the engine is stopped, Since the lock knob cannot be operated and the lock cannot be released, the safety of storing luggage in the trunk room is improved.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, a U-shaped striker 2 is fixed to a rear panel 1 of the vehicle body.

The rear seat bag 3 is connected to a rear seat cushion (not shown) installed at the bottom of the vehicle body so as to be tiltable forward, and when tilted forward, opens a luggage entrance leading to a trunk room opened in the rear panel 1.

The rear seat bag 3 closes the luggage entrance of the rear panel 1 when the seat is tilted backward.

A hard case 4 housing a locking mechanism is installed inside the rear seat bag 3.
is provided with a hook 5 that engages with the striker 2 when the rear seat bag 3 is tilted backward.

The hook 5 is pivotally connected to a bracket 6 fixed to the hard case 4 by a pin 7, and a spring 8 is hooked to the hook 5 to bias the hook 5 in the locking direction (downward).

A connecting rod 10 of a lock knob 12 protruding from the upper part of the rear seat bag 3 is connected to the hook 5. When the lock knob 12 is pulled up, the connecting rod 10 is raised and the hook 5 is swung in the unlocking direction. When the lock knob 12 is pressed down, the connecting rod 10 is lowered to swing the hook 5 in the locking direction.

The connecting rod 10 has a radial locking hole 10.
a is opened and the solenoid 11 fixed to the rear panel 1 has a solenoid that enters the locking hole 10a when energized,
A locking pin 13 is provided that comes off from the locking hole 10a during demagnetization.

The solenoid 11, as shown in FIG.
It is connected to a switch 14 that turns off when the ignition key is inserted into the key cylinder of the engine.

With the above configuration, when the ignition key is inserted into the key cylinder of the engine, the switch 14 is turned off and the solenoid 11 is turned off.
is demagnetized and the locking pin 13 comes out of the locking hole 10a of the connecting rod 10, so that when the lock knob 12 is pulled up, the hook 5 is swung in the unlocking direction via the connecting rod 10.

Therefore, by tilting the seat back 3 forward, luggage can be taken in and out of the trunk room.

On the other hand, if the key is removed, switch 1
4 is turned on, the solenoid 11 is energized, and the locking pin 13 enters the locking hole 10a of the connecting rod 10, so that the lock knob 12 cannot be pulled up.

Therefore, since the rear seat back 3 cannot be tilted forward, the safety of storing luggage in the trunk room is improved.
