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

(Prior Art) In some automobiles, a car room is formed behind the rear seat, and the seat back of the rear seat can be folded up and down so that it can take an upright position and a forward-folded position. Some vehicles have a space above the rear seat back that communicates with the cargo room, essentially increasing the storage space for luggage. As shown in Japanese Utility Model Application Publication No. 54-125022, a locking device for holding the rear seat back in the upright position is provided in such a vehicle, and the operating section of this locking device is normally located on the quarter trim. etc. are provided near the side of the rear seat bag.

However, in the case of the above-mentioned conventional vehicle, when loading large or large amounts of luggage through the opening at the rear of the vehicle with the rear seat back in the forward position, the rear seat back is in the forward position until the cargo is loaded. The steps are cumbersome,
It had the following drawback.

In other words, for example, in the case of a hatchback vehicle,
The lid member that covers the rear of the vehicle body is said to be a hatch door,
In this case, before loading the luggage, open the hatch door and lean forward through the opening at the rear of the vehicle to unlock the rear seat bag, or go into the cabin and unlock the rear seat bag. It is something that must be done.

Furthermore, in cases where the cargo room is used as a trunk room, such as in a compact car, and the trunk room and the interior of the vehicle are separated by a rear seat bag, the lid member that covers the opening of the trunk compartment is called a trunk lid. In this case, it is necessary to enter the vehicle interior and unlock the vehicle before loading the luggage from the trunk side. In particular, if there is no side door for the rear seat, such as a coupe type car, open the side door on the front seat side, fold the front seat back forward, and then get into the rear seat side and unlock it. It becomes necessary.

(Purpose of the invention) The present invention was developed in consideration of the above-mentioned circumstances, and it eliminates the hassle of unlocking the locking device that holds the rear seat bag in the upright position when loading luggage through the opening at the rear of the vehicle body. To provide an automobile seat device which can be easily operated without much effort.

(Structure of the invention) In order to achieve the above-mentioned object, in the present invention, a locking device for holding the rear seat bag in an upright position and a lid member covering an opening at the rear of the vehicle body are interlocked. The lock device is unlocked when the lock is opened.

With this configuration, when loading luggage through the opening at the rear of the vehicle body, if you open the lid member, the rear seat bag will be automatically unlocked, so you can load luggage into the cargo room through this opening. Just by pushing it forward, the rear seat bag will be folded forward. More specifically, in an automobile in which a cargo room is formed behind a rear seat, the cargo room is covered by a lid member provided in an opening at the rear of the vehicle body, and the seat back of the rear seat is adjustable. A locking device is provided for holding the seat bag in the upright position, and the locking device is in a locking position in which it engages with a lock pin provided on the seat bag. and a lock release position for releasing the lock pin, and a first spring for biasing the lock lever in the direction of the lock position. is connected to an opening/closing detection device provided at the rear of the vehicle body facing the lid member via a cable, and the opening/closing detection device is swingable in a direction in which it collides with the lid member. and a second spring that urges the swing lever in the direction of abutting against the lid member, the second spring being stronger than the first spring. When the spring force is increased and the lid member is opened, the movement of the swing lever, which rotates due to the spring force of the second spring, is transmitted to the lock device via the cable. The structure is such that the lock device is unlocked when the lock device is released.

With the above configuration, in addition to the above-described lock release that is immediately linked to the opening operation of the lid member, the opening/closing detection device that detects the opening operation of the lid member can be provided at a position facing the lid member. In order to have enough
There is a large degree of freedom in the installation location of the opening/closing detection device.
Furthermore, since the movement of the swinging lever that constitutes one element of this opening/closing detection device is the movement that releases the lock of the locking device, this swinging lever and the locking device (lock lever) are simply connected by a cable. This is sufficient, and no detailed adjustment work is required when connecting the swing lever and the locking device.

is rotated to the unlocked position, and conversely lever 2
2 is rotated in the opposite direction to the arrow X, the lock lever 13 returns to the lock position, and
The lock position and the unlock position can be freely selected according to the operation of the operation knob 15. Of course, the cable 24 is arranged through the inside of the vehicle body, such as inside the rear end panel 19, so as not to get in the way.

Next, the operation of the above configuration will be explained. Now, from the state where the rear seat back 4 is in the upright position and the locking device 7 is in the locking position,
When the rear seat bag 4 is in the forward folded position and you want to load luggage onto the rear seat bag 4 in the forward folded position through the opening at the rear of the vehicle body, the locking device 7 can be loaded by opening the hatch door 2.
Since the lock is automatically released, if luggage is loaded from the hatch door 2 side and pushed forward, the rear seat back 4 will be pushed by the luggage and will naturally fall into the forward position. In this way, it is not necessary to unlock the locking device 7 by stretching the body forward after opening the hatch door 2, or to enter into the vehicle interior and perform the unlocking operation.

Although the embodiments have been described above, the present invention is not limited thereto, and includes, for example, the following cases.

The rear seat back 4 is divided into left and right,
The left and right seats may be able to independently take the upright position and the forward folded position. In this case, the left and right divided rear seat backs are individually provided with locking devices, and the individual locks are The hatch door 2 may be linked to the device.

For example, one end of the inner cable 24b may be directly connected to the hatch door 2 near the center of rotation (hinge portion) of the hatch door 2 without separately providing the opening/closing detection device 18.

The automobile may be of a so-called notch bag type (three box type).
That is, in this case, the trunk room serving as a cargo room and the vehicle interior are partitioned by the rear seat bag 4, and the trunk room and the vehicle interior are communicated with each other when the rear seat bag is in the forward position.

(Effects of the invention) As is clear from the above, the invention has the following effects:
As soon as you open the lid covering the opening at the rear of the vehicle, the rear seat bag will automatically unlock, so when loading luggage through this opening,
There is no need for a separate unlocking operation to bring the rear seat back to the forward position prior to loading the luggage, and as a result, the procedure up to loading the luggage can be simplified.

In addition, there is a large degree of freedom in where to install the opening/closing detection device that detects the opening operation of the lid member, and there is also the advantage that there is no need to perform detailed adjustment work when connecting the opening/closing detection device and the locking device. .
