Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rear seat device for an automobile, and particularly to one in which the seat back is provided so as to be tiltable toward the seat cushion.

(Prior art) Conventionally, in automobiles, for example,
As disclosed in Japanese Patent No. 22829, the seat back of the rear seat device is provided so as to be tiltable toward the seat cushion, and when the seat back is tilted,
It is generally well known that a vehicle interior is connected to a trunk room so that long objects can be loaded from the trunk room to the vehicle interior.

On the other hand, when a car is parked in a parking lot, etc., the car key may have to be handed over to the parking lot manager, etc., but if the car manager does not store the key properly, the car key may be left in the trunk room of the car. There is a risk that valuables placed there may be stolen. For this reason, conventionally, car keys have been prepared with a main key that can operate all the door and trunk lid locking devices and the main key switch, and a sub key that can only operate the door locking device and main key switch. When a car key must be handed over to a caretaker or the like, a sub-key is given to prevent theft.

(Problem to be solved by the invention) However, as mentioned above, in the case of a car where the seat back of the rear seat device can be tilted, depending on the sub-key given to the manager etc., even if the trunk lid cannot be opened, it can be opened from inside the car. Since it is possible to take out the cargo in the trunk by tilting the seat bag, there is a problem in that it is not possible to sufficiently prevent theft.

Therefore, in order to solve this problem, in the rear seat device, a key cylinder is provided in the lock device that prevents the seatback from tilting, and the key cylinder allows the lock device to be operated in a way that cannot be operated with subkeys, similar to the trunk lid lock device. ,
It is conceivable to configure it so that it can be operated only with the main key (see Japanese Utility Model Application Publication No. 59-91932, etc.).

However, in this case, the locking device that prevents the seatback from tilting requires a dedicated key cylinder, which complicates the overall structure of the locking device, impairs assembly workability, and increases costs. There's a problem. Furthermore, each time the locking device is released and the seat bag is tilted, the main key must be inserted into the key cylinder for operation, which makes the seat bag tilting operation complicated.

The present invention has been devised in view of these points, and its purpose is to make it impossible to tilt the seat back of the rear seat device unless the trunk lid is opened, instead of using a dedicated key cylinder as described above. To prevent theft,
This is intended to be effective in terms of assembly workability, operability, and economy.

Another object of the present invention is to provide a structure in which the relationship between the trunk lid and the seat back can be arbitrarily released, thereby improving usability.

(Means for Solving the Problem) In order to achieve the above object, the solution of the present invention includes a rear seat device in which a seat back can be tilted toward the seat cushion, and a trunk lid that opens and closes a trunk room. In an automobile in which the vehicle interior and the trunk room communicate with each other when the seat bag is tilted, the lock device for preventing the seat bag from tilting in the rear seat device is constructed as follows.

That is, a locking member is rotatably attached to the upper part of the seat bag and is selectively positioned between an inverted position and a tilted position, and when the trunk lid is closed, the locking member is positioned in the inverted position. The structure includes a hook member that engages with the locking member and separates from the locking member when the trunk lid is opened.

(Function) With the above configuration, in the present invention, when the locking member on the upper part of the seatback is positioned in the inverted position and the trunk lid is closed, the hook member engages with the locking member and the seatback is tilted. The block is in a locked state and this locked state cannot be released unless the trunk lid is opened. For this reason, even if the sub-key is given to a parking lot manager, etc., they will not be able to take out the cargo in the trunk by tilting the seat back from inside the vehicle, and this will be sufficient to prevent theft. Become.

On the other hand, when the trunk lid is opened to load a long object, etc., the hook member is released from the locking member in conjunction with the opening of the trunk lid, and the above-mentioned locked state is released. By tilting the seat cushion toward the seat cushion side, long objects can be easily hung from the trunk room into the passenger compartment.

Moreover, the relationship between the seat back and the trunk lid as described above is only exhibited when the locking member is in the inverted position, and not when the locking member is in the tilted position. At certain times, the seat back can be tilted from inside the vehicle regardless of whether the trunk lid is opened or closed, thereby increasing usability.

Furthermore, the locking device for preventing the seatback from tilting does not require a dedicated key cylinder, and its structure itself is relatively simple, so it can improve assembly workability and reduce costs. It is possible to aim for

(Example) Hereinafter, an example of the present invention will be described based on aspects.

In FIG. 1, 1 is a vehicle interior, 2 is a trunk room, and 3 is a floor panel constituting the floor of the vehicle body.
Reference numeral 4 denotes a rear seat device installed on the floor panel 3, and the rear seat device 4 includes a seat cushion 5 and a rear end of the seat cushion that is inverted approximately vertically, and the seat is rotated using its lower end as a fulcrum. The seat bag 6 is provided so as to be tiltable toward the cushion 5 side, and when the seat bag 6 is tilted, the vehicle interior 1 and the trunk room 2 are communicated with each other.

Reference numeral 7 denotes a rear package tray that extends substantially horizontally behind the upper part of the seat bag 6 and partitions the vehicle interior 1 and the trunk room 2. At the rear end of the rear package tray 7, the lower end of the rear window glass 8 is attached. Supported. A trunk lid 9 opens and closes the upper opening 2a of the trunk compartment 2, and the front end of the trunk lid 9 is connected to the lower surface of the rear package tray 7 via a substantially U-shaped hinge arm 10. It is provided so as to be pivotable to open and close using the connecting portion between the hinge arm 10 and the rear package tray 7 as a fulcrum.

Further, reference numeral 11 denotes a lock device for preventing the seat back 6 from tilting in the rear seat device 4, and the lock device 11 locks the trunk compartment 2 above the seat back 6, as shown in detail in FIGS. 2 and 3. A handle-shaped locking member 12 provided on the back facing the locking member 12, and a substantially L-shaped locking member 12 vertically swingably attached to the lower surface of the rear package tray 7 via a support member 13 corresponding to the locking member 12. A hook member 14 is provided. The locking member 12
The attachment parts 12a, 12a to the seat bag 6 are as follows:
The locking member 12 has a square cross section and is rotatably mounted by mounting brackets 15 made of flexible spring plates, and the locking member 12 is in an inverted position substantially perpendicular to the back surface of the seat bag 6. and a tilted position where the seatback 6 is tilted onto the back surface. On the other hand, an engaging portion 14a that can be engaged with the locking member 12 is formed at one end of the hook member 14, and one end of a cable 16 is connected to the other end.
The other end of the cable 16 is connected to the hinge arm 10 near the connection part with the rear package tray 7. Therefore, the hook member 14 swings as the trunk lid 9 is opened and closed, and especially when the locking member 12 is positioned in an inverted position, the locking member 14 swings when the trunk lid 9 is closed.
The locking member 14 is engaged with the locking member 14a, and is disengaged from the locking member 12 when the trunk lid 9 is opened.

Note that 17 is the direction in which the hook member 14 is engaged with the locking member 12 (the opposite direction to the direction in which it rotates due to the tensile force from the cable 16 when the trunk lid 9 is opened).
A coil spring 18 is a support piece that supports the cable 16.

Next, the function and effect of the locking device 11 of the rear seat device 4 in the above embodiment will be explained. When the locking member 12 is positioned in an inverted position on the back surface of the seat back 6 and the trunk lid 9 is closed, , the hook member 14 is in a state in which its engaging portion 14a engages with the locking member 12 to prevent the seat bag 6 from tilting, and this locked state cannot be released unless the trunk lid 9 is opened. Can not. For this reason, even if the sub-key is given to a parking lot manager, etc., it is not possible to tilt the seat bag 6 from inside the vehicle compartment 1 and take out the cargo in the trunk compartment 2, especially valuables, which is sufficient to prevent theft. can be achieved.

On the other hand, when the main key is used to open the trunk lid 9 in order to load a long object, etc., as the trunk lid 9 is opened centering on the joint between the hinge arm 10 and the rear package tray 7, the aforementioned hook The member 14 receives a tensile force from the cable 16 and rotates clockwise in the drawing to separate from the locking member 12, and the locked state caused by the engagement between the hook member 14 and the locking member 12 is released. By pushing the upper part of the seat back 6 toward the front of the vehicle body from the trunk room 2 side with a long object, etc., the seat back 6 can be easily tilted toward the seat cushion 5 side. 2 to the vehicle compartment 1 can be carried out smoothly.

Moreover, the above-mentioned relationship between the seat bag 6 and the trunk lid 9 is exhibited only when the locking member 12 of the locking device 11 is positioned in an inverted position on the back surface of the seat bag 6. When the stop member 12 is in the tilted position, the trunk lid 9
Since the seat back 6 can be tilted from inside the vehicle interior 1 regardless of opening and closing, there are two ways of using the seat bag, and the usability can be improved.

Furthermore, the locking device 11 does not require a dedicated key cylinder, and its structure itself is relatively simple, mainly consisting of the locking member 12 and the hook member 14, so the assembly process is simple. This can be done easily, the reliability of the operation can be increased, and the cost can also be reduced.

(Effect of the invention) As described above, according to the automobile rear seat device of the present invention, when the locking member on the upper part of the seat bag is positioned in the inverted position, the hook member engages with the locking member when the trunk lid is closed. At the same time, the seatback's tilting prevention is locked, and this locked state cannot be released unless the trunk lid is opened.However, when the trunk lid is opened, the above-mentioned hook member is released from the locking member and the locked state is released. This makes it possible to effectively prevent theft of valuables placed in the seat while simplifying the tilting operation of the seat bag. Moreover,
When the locking member is positioned at the tilted position,
The seat back can be tilted from inside the vehicle, regardless of whether the trunk lid is opened or closed.
It can improve usability, and since it does not require a dedicated key cylinder and has a relatively simple configuration, it is excellent in assembly work and economic efficiency, and is extremely advantageous in implementation. .
