Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to folding seats applied to vehicles, etc.
More specifically, for example, a folding seat that is installed in the passenger seat and whose rear legs can be used as a table when the seat is folded forward, and a table that can be used as a table when the rear legs are in the retracted position. This invention relates to a folding sheet that can be used as a storage space.

(Prior Art) While driving a vehicle such as a car, a driver often needs to confirm the route to a destination.
Furthermore, in the case of commercial vehicles such as collection and delivery vehicles, it is essential to fill out forms each time the vehicle is driven.

In such a case, a table with a predetermined area is required on which to spread out the map or place documents such as slips, and conventionally, this type of table has usually been provided in the instrument panel.

However, when installing it on the instrument panel, it has to be installed on the passenger side due to space constraints, which means it is quite far away from the driver, and it is also located near the steering wheel. The steering wheel, etc., got in the way, making it extremely difficult to use while seated.

In addition, the table mentioned above is installed separately, and the table arrangement position mentioned above is not compatible with the layout of standard equipment such as glove boxes.
The design is subject to various restrictions, which complicates the design and increases costs.

Furthermore, the above-mentioned conventional table merely has the function of a table, and from the viewpoint of space saving and cost reduction, there has been a demand for a table having multiple functions.

(Object of the Invention) In view of the above conventional problems, it is an object of the present invention to provide a folding seat equipped with a table that is convenient for the driver, free from layout constraints, and inexpensive in terms of cost. The first objective is to solve the above problems.

In addition to the above-mentioned problems, a second object of the present invention is to provide a folding sheet equipped with a table that can also function as a storage space depending on its usage.

(Structure of the Invention) According to the present invention, the above first object is achieved by:
A seat bag is foldably attached to a seat cushion, a front leg and a rear leg are attached to the seat cushion, the front leg is rotatably supported on the floor of the vehicle body, and the rear leg is pivotably supported on the floor of the vehicle body. In a folding seat in which the seat cushion is installed in the seating position together with the front legs when the lower end abuts the vehicle body floor,
This is achieved by providing a folding seat with a table attached to the rear leg of the seat cushion so that the upper surface can be held substantially horizontally with the seat cushion inverted forward.

According to the present invention, the seat bag is foldably attached to the seat cushion, the front legs and the rear legs are attached to the seat cushion, and the front legs are attached to the vehicle body. In a folding seat that is rotatably supported on a floor, and in which a seat cushion is placed in a seating position together with the front legs when the lower end of the rear legs abuts the floor of the vehicle body,
A table is attached to the rear leg of the seat cushion so that the upper surface of the seat cushion can be held substantially horizontally when the seat cushion is inverted forward. The base end of the rear leg is rotatably connected to the seat cushion, and the rear leg is attached to the pivot portion with the seat cushion in the seating position. This is accomplished by providing a folding seat with a locking mechanism lockable to the seat cushion.

(Effects of the Invention) In the first invention having the above configuration, by attaching a table to the rear legs of the seat cushion, it can be used as a general seat in the normal position, and the table can be attached to the rear legs of the seat cushion. When you want to use it, you just need to rotate the seat cushion of the folding seat forward and bring it down to a predetermined position where the top surface of the table can be used, so the operation is very simple.

Further, there is no need to provide a separate table as in the conventional case, and there is no disadvantage that the design becomes complicated due to the layout and relationship with other standard equipment, which requires time and effort to manufacture, and increases costs.

Furthermore, by being attached to the rear legs, the table also functions as a reinforcing plate for the rear legs, thereby improving the rigidity and strength of the rear legs.

In addition, when used as a passenger seat, the table can be placed in the position that is most convenient for the driver, and the driver can use it while seated, improving work efficiency. It will be possible to improve the results.

In addition, in the second invention having the above configuration, in addition to the above effects, when the rear legs are in the retracted state, the table can be used as a storage space, so there is no need to install a separate storage space, which saves space. It saves money and can be provided at a lower cost.

Furthermore, the use as a table and storage can be changed extremely easily and quickly by locking the lock mechanism or releasing the lock, reducing the burden on the user. Can be done.

By pulling in the direction of the arrow in FIG. 4 to disengage at least the distal end locking portion 18a and the engagement hole 17, the locked state is released and the rear leg 9 can be rotated relative to the bracket 8. The lock mechanism 15 is configured so that

Next, the operation of this embodiment will be explained.

In the normal use state as a passenger seat shown in FIG. 1, the rear legs 9 are in a locked state fixed to the bracket 8 by the locking mechanism 15, and function as normal rear legs.

Therefore, when the driver needs to use the table 10 to check the route to the destination by looking at a map, or to fill in and organize necessary information on a slip, etc., the driver can use the table 10 as shown in Figure 2. As shown in the figure, the seat back 3 of the folding seat 1 is first folded toward the seat cushion 2, and then the seat 1 is rotated forward, that is, counterclockwise in the figure, about the pivot 61 of the front leg 6, and the seat back 3 of the folding seat 1 is folded toward the seat cushion 2. Push it down to a predetermined position where the seat cushion 2 abuts and locks on the surface F.

In conjunction with this, the rear legs 9 integrated with the table 10
rotates upward, and in the locking position of the seat cushion 2, the upper surface 101 of the table 10 is in a substantially horizontal usable position. leg 9
The relative positional relationship between the two may be set in advance.

After the table 10 is used for the above-mentioned predetermined work in the usable position, the seat cushion 2 is rotated in the clockwise direction in FIG. Simply rotate the seat bag 3 to raise it up again and return it to the normal use position shown in FIG.

In addition, when the table 10 is in the usable state shown in FIG. 2, if the table 10 temporarily interferes with other work, pull the knob 19 of the locking mechanism 15 outward to remove the bracket 8 and the rear. What is necessary is to release the lock with the leg base end 9a and rotate the rear leg 9 to the retracted position shown by the imaginary line in FIG.

When the table 10 is to be used again, the rear legs 9 are rotated to the usable position of the table 10 in the opposite manner as described above, and the end locking portion 18a of the locking member 18 is engaged with the engagement hole 16 by the biasing force of the spring 20. 17, and the rear legs 9 are locked again.

In this embodiment, the rear legs 9 of the folding seat 1 are used, and the table 10 is integrally installed therein, so compared to the conventional example in which the table is installed separately on an instrument panel (not shown), etc. There are no restrictions on the layout,
The design is simplified and can be manufactured at low cost without causing problems in the design of other parts.

Further, since the table 10 is integrated with the main body of the rear leg 9, it also functions as a reinforcing plate for the rear leg 9, and can improve bending strength and rigidity in in-plane and out-of-plane directions.

Further, in this embodiment, since a folding seat is provided as a passenger seat, the table 10 can be placed in the usable position at a position that is most convenient for the driver, and the driver can sit in the seat. It is easy to use and greatly improves various work efficiency.

Furthermore, the table 10 itself can be stored together with the rear legs, so it does not get in the way of other work.
You can set it to any position where it can be used only when you want to use it.

Next, FIGS. 5 and 6 show other embodiments,
Elements that are the same as those in the first embodiment are given the same reference numerals and their explanations will be omitted.

In this embodiment, the table 10 is not shaped like a flat plate, but is formed into a hollow box shape with an opening on the rear leg base end 9a side, so that the upper surface 101 can be used as the original table surface. .

In this embodiment as well, the rear leg proximal end 9a can be locked in a predetermined positional relationship with the seat cushion 2 via the bracket 8 by the locking mechanism 15, so that the seat back can be locked as shown in FIG. 3 and fold it down to a predetermined position in front of the seat cushion 2, the top surface 10 of the table 10
1 is set so that it is in a position where it can be used as an original table if the lock mechanism 15 is activated.

In addition, in the state shown in FIG. 5, if the lock mechanism 15 is released, the rear legs 9 are moved to
At the same time, it can be rotated in the direction shown by the arrow in FIG. 5, and can be moved to the retracted position where it abuts and locks the seat cushion 2, as shown in FIG.

Therefore, in the storage position, the table 10 is in a state where its opening 10a is positioned upward as shown in FIG. 6, and the box-shaped hollow interior can be used as a storage container for storing various small items. .

In addition, in the first and second embodiments described above, an example was shown in which the table 10 is set in a horizontal position where it can be used when the seat cushion 2 is brought down to the position where it contacts the vehicle floor surface F. In addition, for example, the positional relationship may be set so that the seat cushion 2 is locked to an instrument panel or the like (not shown) located in front of the folding seat 1, and the seat cushion 2 may be in the locked state. The relative positional relationship of the rear legs 9 to the seat cushion 2 may be set in advance so that the table 10 is in a horizontal position. The length can be set arbitrarily.

Furthermore, the table 10 does not necessarily have to be horizontal in its usable position; it can be used in a state where it is inclined to a certain degree with respect to the horizontal plane, as long as it can hold maps and documents, such as with the binder 12 in the first embodiment. It is also possible to set it as a possible position, and the inclination may be adjusted to some extent, and the upper surface 10 does not necessarily have to be a smooth surface.

Further, in the first and second embodiments, the front legs 6 of the seat cushion 2 are rotatable and the table 10 is integrally attached to the rear legs 9, but in contrast, the table 10 is attached to the front legs 6. The rear legs 9 may be attached so that the rear legs 9 are rotatable, so that when the folding sheet 1 is rotated backward and folded down to a predetermined position, the table 10 is in the usable position.

Furthermore, in addition to being used as a passenger seat, the folding seat 1 according to the present invention can be arranged in any manner, such as being installed in the rear seat position, etc., without departing from the gist of the present invention. It goes without saying that modifications and changes are possible.
