Description

[Detailed description of the invention] The present invention relates to a seat table for aircraft, buses, railway vehicles, etc., and particularly for seats that are attached to the rear of the seat back of the seat and can be horizontally extended to the rear of the seat back when in use. It's about tables.

A table that is attached to the back of the seat back of a seat in an airplane, bus, railway vehicle, etc. and used by rear seat passengers is such that when not in use, the table and all of the supports that support the table are housed in the recess formed in the back of the seat back. ing. When using this table, pull out the table and support to the rear of the seat bag, lock the support that is pivoted at the lower end at a predetermined angle,
The table, which is pivoted to the upper end of the support, is unfolded so as to be maintained horizontally by its own weight. In order to regulate the rotation of this support at a predetermined position, as shown in FIG. A stopper 5 against which the adjustment screw 7 contacts is arranged at the bottom. However, the contact area between the adjustment screw 7 and the stopper 5 is exposed to passengers in the rear seat, that is, the user, and if the table is carelessly unfolded, fingers or feet may fall into this contact area. There was a risk of getting your fingers caught and getting injured.

The present invention was developed in view of the above-mentioned problems and to solve the problems, and the stopper and the adjustment screw that comes into contact with the stopper are housed in a U-shaped bearing part formed at the lower end of the support at all times. It is an object of the present invention to provide a seating table with improved safety for the user by having a structure in which the contact portion is not exposed to the user side of the table.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 2 to 5, 11 is a table;
A support 12 rotatably supports both left and right sides of the table 11 at its upper end.
The table 11 is pivotally supported by the upper end of the support 12 behind its center of gravity so that it can maintain a horizontal state during use by its own weight, and between the rear end and the upper end of the support 12. The stay 1 is installed to prevent over-rotation of the table 11.
3 is interposed. When the support 12 is rotated to a predetermined position, the table 11 rotates on its bearing portion 14 and is locked in a position regulated by the stay 13, that is, in a horizontal state.
The support 12 configured as described above is rotatably attached to a seat bag (not shown) at its lower end. Support 12 in this invention
A bearing part 14 projecting diagonally downward in a U-shape is formed at the lower end of the seat, and a stopper 15 which is fixed to the seat back side and does not rotate is interposed within the bearing part 14. This stopper 15 is fixed coaxially with the bearing part 14 of the support 12 on one side, and has a locking part 16 protruding in the rotational direction of the bearing part 14 on the other side.
The support 12 is adapted to rotate with the stopper 15 inserted into its bearing portion 14. Further, the stopper 15 has a structure in which the lower end of the other side is fixed to the frame (not shown) on the seat back side, so that the support 12 is always connected between two points via the stopper 12. It is gaining support. An adjustment screw 17 is attached to the bearing part 14 of the support 12 having the above structure, which projects into the bearing part 14 from above and whose projecting end can come into contact with the locking part 16 of the stopper 15. When the support 12 is tilted toward the rear of the seat bag, the protruding end of the adjustment screw 17 is brought into contact with the locking portion 16 of the stopper 15 at a predetermined position, thereby preventing over-rotation. The angle of inclination of the support 12 can be adjusted by changing the protrusion length of the adjustment screw 17 into the bearing portion 14.

Since the present invention is constructed as described above, the abutment part between the stopper that regulates the rotation angle of the support and the adjustment screw is not exposed to the user side of the table, and the table can be used safely. Adjustment screws can be adjusted efficiently from above the support, improving operability and increasing the stability of the support itself.
The practical effects after implementation of this invention are excellent.
