Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automobile trunk opening/closing device.

(Prior Art) It is generally known that a rear seat bag of an automobile separates a trunk room from a passenger compartment, and the seat bag can be folded forward to allow luggage to be taken in and out of the trunk room from the passenger compartment side. In this case, it is desirable that the seat bag be held in an upright position relative to the vehicle body, that is, that it can be locked, in order to prevent the seat bag from accidentally tipping forward while driving and to prevent luggage in the trunk room from being stolen due to someone else's forward folding operation.

In response to this, the rear seat back can be locked to the vehicle body in an upright position, and the seat back is equipped with a release mechanism that releases the lock by operating a knob, and a mechanism that cancels the operation of this release mechanism by operating a key. A locking device is known (for example, see Japanese Utility Model Application No. 59-91932). In the case of this conventional technology, the communication port between the passenger compartment and the trunk room is blocked only by the seat back, and it is difficult to prevent the air inside the vehicle from leaking from the gap between the seat back and the periphery of the communication port. Therefore, the efficiency of heating and cooling inside the vehicle may be reduced. To solve this problem, it is conceivable to provide a cover member on the back of the seat bag to block the above-mentioned communication port so that this cover member can be locked in the closed state. There is a regret that this will make the operation complicated, as it will always be forced to move forward.

(Purpose of the invention) In view of the above, the present invention is designed to partition the trunk room of the vehicle interior with the seat back of the rear seat, while preventing a decrease in the efficiency of air conditioning and heating.
The purpose is to make it easier to take items in and out of the trunk.

(Structure of the invention) The present invention is a trunk room opening/closing device for an automobile, in which the interior of the vehicle and the trunk are separated by a seat bag of the rear seat that can be folded forward, and a communication port between the interior of the vehicle and the trunk when the seat bag is folded forward is provided on the back side of the seat bag. A cover member that can be opened and closed is provided. A lock portion for engaging the cover member with the communication port in a closed state and a key cylinder for releasing the engaged state of the lock portion by key operation are provided between the cover member and the vehicle body. A locking means is provided, and a small opening is provided in the cover member to communicate the vehicle interior and the trunk room.

In the case of this trunk room opening/closing device, the passenger compartment and trunk room are double partitioned by the seat back and the cover member, and when the seat back is tilted forward, the passenger compartment and trunk room are communicated only through a small opening. However, when the cover member is opened by operating a key, the vehicle interior and the trunk room communicate with each other through a large communication port.

(Effects of the invention) Therefore, according to the invention, since the vehicle interior and the trunk room are double partitioned by the seat back and the cover member, it is possible to prevent a decrease in the efficiency of air conditioning in the vehicle interior, and at the same time, it is possible to prevent the efficiency of cooling and heating in the vehicle interior from decreasing. Small items can be taken in and out of the trunk room through the small opening without having to topple the cover member, and large items can also be taken in and taken out from the communication port by folding down the cover member. Since the cover member can be locked with a key, it is possible to prevent theft of large items that cannot pass through the small opening, and even small items can be stored in the rear of the trunk where they cannot be reached through the small opening. For example, theft can be prevented.

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

In the rear structure of an automobile shown in FIG. 1, 1 is a trunk room, 2 is a rear seat, and the rear seat 2 has a seat cushion 3 with left and right seating parts integrated, and a seat back 4, 4 that is divided into two parts on the left and right. Equipped with The vehicle interior and the trunk room 1 can be double partitioned by the seat backs 4, 4 and a cover member 5 provided on the back side thereof.

That is, the cover member 5 is provided with a small opening 6 in the center of its lower part through which a person's hand can be inserted, and as shown in FIG. It is supported by a coaxial hinge 8 so as to be rotatable forward. When the seat back 4 and the cover member 5 are in the upright state, they completely close the communication opening 9 between the vehicle interior and the trunk room 1 (see Fig. 3), and when only the seat back 4 is tilted forward, the small opening 6 in the cover member 5 opens. When the cover member 5 is opened and the cover member 5 is folded down, the communication port 9 will be opened.

However, the seat back 4 and the vehicle body 7 behind it
As shown in FIG. 2, an engaging means 10 is provided between the cover member 5 and the vehicle body 7 to engage the vehicle body 7 with the seat back 4 in the upright state. A locking means 11 is provided which can engage the vehicle body 7 and lock the engaged state.

The engagement means 10 of the seat back 4 includes a substantially U-shaped striker 12 that is fixed to the vehicle body 7 and projects forward, and an engagement member that is rotatably supported by the seat back 4 with a pin and can be engaged with the striker 12. Part 1
3. This engaging member 13 is biased by a spring (not shown) in a rotating direction in which it engages with the striker 12, and is connected by a rod 15 to an operating knob 14 protruding from the upper surface of the seat bag 4.

As shown in FIGS. 4 and 5, the locking means 11 of the cover member 5 includes a locking portion 16 that engages the cover member 5 with the vehicle body 7 in an upright state, and a locking portion 11 that holds the locking portion 16 in the engaged state and A key cylinder 17 for releasing the release is provided. Lock part 16
is a striker 1 that protrudes forward from the vehicle body 7.
8, and a hook member 19 rotatably supported on the cover member 5 side so as to be able to engage with the striker 18.

First, the key cylinder 17 and the hook member 19
is the bottom wall 20 of the case 20 fixed to the cover member 5.
It is supported by a. The hook member 19 has a hook portion 19a that protrudes rearward from the bottom wall 20a, and the base portion 19
b protrudes into the case 20, and the spring 2
1 in the direction of engagement with the striker 18.

The key cylinder 1 is attached to the holding cylinder 20c of the case 20 holding the sea cylinder 17 as shown in FIG.
A locking groove 23 and an unlocking groove 24 from which the lock plate 22 protrudes from the outer periphery of the key cylinder 17 are formed, and an interlocking member that protrudes from the outer periphery of the key cylinder 17 and can come into contact with the base 19b of the hook member 19. A notch 26 is formed to allow the rotation of 25.

Further, a pinion gear 27 is rotatably fitted to the lower end of the key cylinder 17, and
A slide member 29 having a rack gear 28 that meshes with the pinion gear 27 is provided inside the slide member 29 so as to be slidable left and right. And pinion gear 2
A fan-shaped groove 30 is formed in the inner circumference of the key cylinder 1 as shown in FIG.
A protrusion 31 protruding from the outer periphery of 7 is inserted. The slide member 29 is provided with a protrusion 29a that can come into contact with the back of the interlocking member 25 of the key cylinder 17 at a position opposite to the rack gear 28. It is biased in the direction of contact. In addition, in FIG. 5 and FIG. 6, 33 is a keyway.

Therefore, in the case of the above embodiment, the seat back 4
is the engagement member 13 of the engagement means 10 and the striker 1
2, the cover member 5 locks the locking means 1.
Due to the engagement between the first hook member 19 and the striker 18, each is held in an upright state relative to the vehicle body 7. In this upright state, the communication port 9 between the vehicle interior and the trunk room 1 is divided into two layers by the seat back 4 and the cover member 5, and there is no air circulation between the vehicle interior and the trunk room 1, and there is no air flow between the vehicle interior and the trunk room 1. This prevents a decrease in heating and cooling efficiency. In this case, the seat bag 4 seals the small opening 6 of the cover member 5, and the cover member 5 seals the communication opening 9.

Then, when the operating knob 14 of the seat bag 4 is pulled up to disengage the engagement means 10, the seat bag 4
can be tilted forward, thereby allowing access to the passenger compartment and trunk compartment 1 through the small opening 6 of the cover member 5.
Since these are in communication with each other, small items can be taken in and out of the trunk compartment 1 from inside the vehicle through the small opening 6 without having to topple the cover member 5.

When taking a large item into or out of the trunk 1, when the key cylinder 17 of the locking means 11 is in the unlocked state (the locking plate 22 is in the unlocking groove 24), the sliding member 29 is moved as shown by the chain line in FIG. When pushed to the left, the protrusion 29a hits the interlocking member 25, and the interlocking member 2
5 rotates counterclockwise together with the key cylinder 17. As a result, the hook member 19 is attached to the base 1.
9b is pushed and rotated by the interlocking member 25, the engagement of the hook portion 19a with the striker 18 is released, and the cover member 5 can be tilted forward. By folding the cover member 5 forward, the communication port 9
opens, allowing large items to be taken in and out of the trunk compartment 1 from inside the vehicle.

On the other hand, when the key cylinder 17 of the locking means 11 is rotated 90 degrees clockwise by key operation,
The lock plate 22 fits into the lock groove 23.

At this time, the interlocking member 25 rotates clockwise together with the key cylinder 17, and reaches a position where it does not interfere with the protrusion 29a of the slide member 29, as shown by the chain line in FIG. At the same time, a protrusion 3 protruding from the key cylinder 17 to the opposite side of the interlocking member 25
1, after the interlocking member 25 no longer interferes with the protrusion 29 of the slide member 29, it comes into contact with the pinion gear 27 at the left end of the fan-shaped groove 30, and similarly rotates the pinion gear 27 in the clockwise direction. As a result, the slide member 29 moves to the left, and the case 2
0 is hidden under the upper wall 20b.

In this state, the slide member 29 cannot move to the left, and the interlocking member 25 or the hook member 19
Since the hook member 19 cannot come into contact with the vehicle body 7,
The cover member 5 is held in a state where it is engaged with the striker 18, that is, it is locked, and the cover member 5 cannot be tilted forward. Therefore, unless the lock of the hook member 19 is released by key operation,
This prevents the cover member 5 from being tipped forward and the resulting theft of items in the trunk room 1 by someone else. In this locked state, since the slide member 29 is hidden behind the upper wall 20b of the case 20, it can be seen from the outside whether it is in the locked state or not. Of course, theft can be prevented by storing small items in the trunk 1 out of reach through the small opening 6 of the cover member 5.

The engaging member and the striker of the engaging means, and the hook member and the striker of the locking means may be attached to the seat bag and the vehicle body, or the cover member and the vehicle body, respectively, in a positional relationship opposite to that of the embodiment.

Further, in the embodiment, the seat bag is divided into left and right parts, but the present invention can also be applied to a seat bag in which the left and right parts are integrated. Further, a plurality of small openings may be provided.
