FIELD OF THE INVENTION
The present invention relates to a table for a motor vehicle seat. More particularly, the invention relates to a table for a motor vehicle seat, which can be attached to a seat of a motor vehicle at an adjustable height and an adjustable angle in relation to the seat. The table for a motor vehicle seat according to the present invention is used, for example, for writing, reading, eating and using a computer in a motor vehicle.
BACKGROUND OF THE INVENTION
Various tables for a motor vehicle seat are known. These tables comprise a plate-shaped table attached to the back of a motor vehicle seat by attaching means or supporting means.
However, in the prior art tables, the means for attaching the table to the back of a motor vehicle seat and the means for supporting the table on the back of a motor vehicle seat are complicated and expensive. Furthermore, in the prior art tables, it is difficult to attach the table to the back of a motor vehicle seat and detach the table therefrom.
It is an object of the invention to obviate all of the above-mentioned disadvantages of the prior art.
It is another object of the invention to provide a table for a motor vehicle seat, which is simpler and less expensive than prior art tables.
It is a further object of the invention to provide a table for a motor vehicle seat, which can be easily attached to a motor vehicle seat and easily detached therefrom.
These and other objects have been achieved by the following table for a motor vehicle seat.
BRIEF SUMMARY OF THE INVENTION
First, the present invention is a table for a motor vehicle seat comprising a table supporting means, said table supporting means being provided at an upper end thereof with a loop, said loop being hung on a headrest of a motor vehicle seat so that said table supporting means is positioned substantially vertically, said loop being removable from said headrest, a table having a table holding means, said table holding means holding said table vertically rotatably by means of a horizontal shaft, said table holding means being provided with a vertical hole, said vertical hole having a larger diameter than said table supporting means, said table supporting means being passed through said vertical hole of said table holding means, a vertical bolt being threadedly engaged with said table holding means, a lower end of said vertical bolt being in contact with a base portion of said table so as to maintain said table at a desired angle.
In this embodiment, the table for a motor vehicle seat can be easily attached to a motor vehicle seat and easily detached therefrom because the table supporting means is provided at an upper end thereof with a loop which can be removably hung on a headrest of a motor vehicle seat.
The table for a motor vehicle seat is simpler and less expensive than prior art tables.
The table holding means is usually inclined in relation to the table supporting means by the weight of the table itself and the weight of a thing put on the table. This means that a lower end on a side near the table (See reference symbol “a” in
FIGS. 4 and 5
.) and an upper end on an opposite side (See reference symbol “b” in
FIGS. 4 and 5
.) of the vertical hole of the table holding means are pressed against the table supporting means. Therefore, the height of the table holding means is fixed in relation to the table supporting means. As a result, the height of the table attached to the table holding means is also fixed.
The height of the table can be adjusted by slightly lifting the table by hand so that the vertical hole of the table holding means is substantially parallel to the table supporting means and moving the table and the table holding means upwardly or downwardly to a desired position. When the table is set free, the table holding means is inclined again in relation to the table supporting means by the weight of the table, and the height of the table is fixed.
The base portion of the table has a tendency to be turned upwardly by the weight of the table itself and the weight of a thing put on the table. However, the table is fixed at a desired angle, without being turned, because the lower end of the vertical bolt, which is threadedly engaged with the table holding means, is kept in contact with the base portion of the table.
The angle of the table can be adjusted by rotating the vertical bolt, which is threadedly engaged with the table holding means, to change the height of the lower end of the vertical bolt. The table is fixed at the desired angle because the lower end of the vertical bolt is in contact with the base portion of the table.
Second, in the table for a motor vehicle seat described above, said table supporting means is provided with two parallel members, said table having two said table holding means, each of said parallel members being passed through each vertical hole of said table holding means.
In this embodiment, the table is very stable because the two table holding means are supported respectively by the two parallel members.
Third, in the table for a motor vehicle seat described above, said table supporting means is attachable to any of a front surface and a rear surface of a back of a motor vehicle seat.
When the table supporting means is attached to a front surface of the back of a front seat in a motor vehicle, the table is positioned in front of the front seat, and the table is used in a front seat beside said front seat. See FIG.
1
. When the table supporting means is attached to a front surface of the back of a rear seat in a motor vehicle, the table is positioned in front of the rear seat, and the table is used in a front seat. See FIG.
1
. When the table supporting means is attached to a rear surface of the back of a front seat in a motor vehicle, the table is positioned at the rear of the front seat, and the table is used in a rear seat. See FIG.
