Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a seat storage device installed in a luggage compartment of an automobile.

(Prior Art) As a conventional seat storage device, for example, one described in Japanese Utility Model Application Publication No. 50-20322 is known.

In this conventional seat storage device, a foldable seat equipped with a seat cushion and a seat back is provided on the floor of the luggage compartment of the vehicle, and two levers are installed at one end of each in the storage section below the floor. The lever is pivotally supported by a first support shaft, and the other end of the lever extends from the storage position located below the floor to the use position located above the floor.
It is movable by rotation around a support shaft, and is connected to the seat cushion via a second support shaft, and the seat and lever are movable by rotation around the first and second support shafts. It was provided so that it could be stored in the storage section.

Therefore, by rotating the seat around the first and second support shafts and rotating the lever around the first support shaft, the seat can be stored in the storage section or placed on the floor. It was possible to move it to the position of use.

In addition, Japanese Utility Model Publication No. 56-127144 discloses a structure in which a part of the vehicle body floor is lowered, a rear seat is folded and stored in the lowered part, and the back of the seat back and the vehicle floor are on the same plane. What was done is listed.

(Problem to be solved by the invention) However, in the conventional seat storage device as described above, when the seat is rotated, the second support shaft, which is the rotation center of the seat, is not connected to the first support shaft. Since the seat rotates around an axis, there is a problem that the rotation axis position is not fixed and operation is difficult.For example, to prevent the seat rotation axis from shifting, the seat must be aligned with the lever. This requires a delicate procedure, such as pulling the seat and lever simultaneously around the first supporting shaft, which is a fixed shaft, while maintaining the tension. The conventional device provided here has a problem in that unless the rotations of both levers are synchronized, the seat will be inclined with respect to both support shafts, and the rotation will not proceed smoothly.

In addition, in the second conventional example, since the seat is stored at the bottom of the vehicle floor, a storage section must be formed in the vehicle floor, which complicates the manufacturing process of the vehicle body and increases costs. However, since the seat simply rotates and is retracted, there is also the drawback that it can come into contact with the vehicle floor and cause scratches.

(Means for Solving the Problems) The present invention aims to solve the above-mentioned conventional problems, and in order to achieve this purpose, the seat storage device of the present invention has a seat storage device. A seat on which a seat bag can be folded is provided so as to be placed on the floor surface of the vehicle body, and a storage portion capable of storing the seat is formed on the side of the floor surface on which the seat is placed. Insert one end into the first
A lever is provided that is pivotally supported by a support shaft and is rotatable from a first position in which the other end is disposed within the storage section to a second position in which the other end is disposed outside the storage section; At the end, the side of the seat cushion
The lever is pivotably supported by a support shaft and is rotatable until the seat cushion is placed on the floor surface at the second position of the lever, and the entire seat is retracted at the first position of the lever. The lever is formed to be rotatable until it is stored in the unit, and the lever is provided with a biasing member that biases the lever to rotate in the direction of the second position, and the lever is disposed in the first position. A lock mechanism is provided that is in a locked state and restricts rotation of the lever by the biasing member, and a guide pin is provided on the side of the seat opposite to the second support shaft, and A slide guide is provided at the bottom of the storage section at a position that overlaps with the guide pin when the seat is rotated toward the storage section, and the slide guide is provided with a second lever.
When the seat is rotated toward the storage section by the second support shaft while the seat is placed in the position shown in FIG. a guide surface that slides and guides the guide pin during relative displacement between the seat and the storage section due to rotation in the first position direction;
A guide groove is formed continuously on the guide surface and engages with the guide pin to restrict upward movement of the guide pin when the lever is moved to the first position to lock the lock mechanism. The means by which it is formed.

Therefore, in the seat storage device of the present invention, the following procedure is used to move the seat from the storage section onto the floor surface.

First, the restriction on rotation of the lever by the lock mechanism is released, and the lever is rotated from the first position to the second position about the first support shaft by the urging force of the urging member.

Next, the seat is lifted and rotated about the second support shaft, and the seat cushion is placed on the floor of the vehicle body. In this state, the seat back is pulled up and the seat becomes ready for seating.

If the biasing force of the biasing member is strong, the lever will be rotated all at once to the second position when the rotation restriction by the lock mechanism is released, and the lever will be rotated to the second position due to the weight of the seat. Even if the seat is only rotated to the front, it will be rotated to the second position when the seat is subsequently lifted as described above.

Next, the storage procedure will be explained.

First, the seat bag is folded onto the seat cushion, and then the seat is rotated about the second support shaft toward the storage section. Then, before the seat comes into contact with the bottom of the storage section, the guide pin provided on the seat engages with the guide surface of the slide guide.

At this time, since the lever is biased toward the second position by the biasing member, the lever hardly rotates toward the first position, and therefore,
The position of the second support shaft is stable, and the seat rotates around the second support shaft of the lever in the second position, so that the guide pin smoothly engages with the guide surface. By the way, if the lever is not provided with a biasing member, when the seat is moved toward the storage section, the seat rotates around the second support shaft and the lever simultaneously rotates around the first support shaft. If the sheet moves with rotation about two axes in this way, it becomes difficult to bring the guide pin into contact with the guide surface.

After the guide pin of the seat is engaged with the guide surface of the slide guide as described above, when the lever is rotated about the first support shaft in the direction of the first position against the biasing force of the biasing member. As the second support shaft moves accordingly, the seat is displaced, and the guide pin provided on the seat slides along the guide surface of the slide guide. Then, when the lever reaches the first position and the locking mechanism enters the locked state, the guide pin reaches the position of the guide groove, engages with the guide groove, and is restricted from moving upward.

This completes the storage of the seat. In this stored state, the seat is restricted from rotating on the side that is pivoted by the lever by the locking mechanism, and is restricted from moving upward on the opposite side. becomes.

These guide pins 91 and slide guides 92 are used to position the seat back 12 above the bottom surface of the storage section 30 by engaging the guide pin 91 when the auxiliary seat 10 is stored or taken out from the storage section 30. This prevents the back surface and the bottom surface of the storage section 30 from rubbing against each other.

Further, reference numeral 99 in the figure is a storage section, which is formed on the left side between the extension floor 102 and the seat floor 104, and is used to store a handcart for carrying luggage, tools, and the like.

Next, the operation of the embodiment will be explained.

When the auxiliary seat 10 is in use, the striker 21 on the back side of the seat cushion 11 is engaged with the locking device 22, so that the auxiliary seat 10 is fixed to the extension floor 102.

When the auxiliary seat 10 is stored in the storage section 30.

First, the seat bag 12 is rotated forward by the hinge 13 to fold up the auxiliary seat 10, and the lock release lever 23 is operated to remove the striker 21 from the lock device 22.

Next, the auxiliary seat 10 is rotated to the right around the upshaft 60 until the guide pin 91 engages with the guide surface 921 of the slide guide 92.

At this time, the lever 40 remains in the use position where it is in contact with the stopper edge 33 due to the biasing force of the spring 70 and does not rotate.

When the auxiliary sheet 10 is pushed into the storage section 30 with the guide pin 91 engaged, the auxiliary sheet 10 reaches the guide groove 920 with the guide pin 91 sliding along the guide surface 921. Thereby, the back surface of the seat bag 12 and the bottom surface of the storage section 30 are stored without rubbing against each other, and furthermore, movement in the vertical direction is restricted in this state.

In conjunction with the retraction of the auxiliary seat 10, the lever 40 also moves the spring 7 around the lower shaft 50.
The upper end of the lever 40 is rotated from the use position to the storage position against the urging force of 0, and is stored in the storage section 30.

Then, as shown in FIG. 4, the striker 81 provided on the lever 40 is engaged with the locking device 82, and the lever 40 enters a locked state in which rotation is restricted. Further, by restricting the rotation of the lever 40 and engaging the guide pin 9 described above, the auxiliary seat 1
0 is also fixed, and then the lid 31 is closed to complete the storage.

In addition, when the lever 40 and the auxiliary seat 10 are in the retracted state, the lever 40 does not protrude above the floor surface, and the lid 31 is positioned flush with the floor surface 3 by the stopper 36, so that the luggage compartment 101 A flat floor surface can be obtained.

Next, when returning the auxiliary seat 10 from the stored state to the used state.

First, open the lid 31 and operate the lock release lever 83 to remove the striker 81 from the lock device 82.

Then, the lever 40 is rotated upward around the lower shaft 50 to the use position where it comes into contact with the stopper edge 33 by the biasing force of the spring 70.

Then, as shown in FIG. 5, when the rotation of the lever 40 is in the use position where the stopper edge 33 restricts it and the upper shaft 60 at the upper edge of the lever 40 is positioned on the floor, lift up the auxiliary seat 10. and rotate the shaft 60 upwardly.

At this time, the lever 40 is rotated upward by the spring 70, so that the upper shaft 60 is restricted to the use position and is not moved while the auxiliary seat 10 is rotating.

Thereafter, when the auxiliary seat 10 is installed on the extension floor 102, the striker 21 is automatically engaged with the locking device 22, and the auxiliary seat 10 is
It is fixed to the extension floor 102 by a seat side locking mechanism 20.

The seat bag 12 is then rotated upright to be in use.

Furthermore, since the storage section 99 is provided in the lower part of the extension floor 102 on the left side in the vehicle width direction where there is no seat in front of it, it is easy to take things in and out of the storage section 99.

Further, since the auxiliary seat 10 is also located on the left side with no obstacles in front of it in the use position, it is easy to sit on.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, instead of a spring, the biasing member may be an elastic material such as rubber, a telescopic member using sealed gas or liquid, such as a gas stay, or the like.

Further, in the embodiment, the storage section is formed in the extended floor, but it may be provided at another location, such as using the side of the driver's seat as the storage section and storing the auxiliary seat there.

Moreover, the number of connection levers provided on the lever may be one, or a plurality of levers may be provided.

(Effect of the invention) As explained above, in the seat storage device of the invention, the lever is provided with a biasing member that biases the lever to rotate in the direction of the use position, and the rotation of the lever by the biasing member is directed to the storage position. When the seat is removed from the storage section, the lever is rotated by the biasing force of the biasing member, and the second support shaft, which is the center of rotation of the seat, is aligned with the floor surface. Since the second support shaft can be positioned above the floor and the biasing member can prevent the second support shaft from moving below the floor surface during rotation of the seat, the second support shaft can be positioned above the floor during rotation of the seat. The shaft does not move, and the seat can be rotated very easily.

Further, even when a plurality of levers are provided, the second support shafts of both levers can be positioned coaxially by the biasing member, and rotational operability can be improved.

Additionally, when storing the auxiliary seat, the guide pin and slide guide prevent the back of the seat back and the bottom of the storage area from rubbing against each other, which prevents damage to the seat back due to frictional force. .
