Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rear table attached to the back of a seat, and more particularly to a structure for supporting the table with an armrest of the seat when the rear table is used.

2. Description of the Related Art Generally, there is a rear table of a structure in which, for example, a table is rotatably provided on the back of a seat of an automobile or a passenger car, and this table is extended to the rear of the seat to be used as a table. However, the conventional rear table has a structure in which the overhanging table is supported by a special stay installed between the table and the seat. Therefore, when using the rear table, the support stay is stretched between the table and the seat, which hinders the freedom of movement around the table.

The purpose of the present invention is to solve the above-mentioned conventional problems by mounting an armrest movably or rotatably relative to the seat back, and by arranging the armrest behind the seat back.
To provide a rear table capable of supporting a table rotatably attached to the back of a seat in an overhanging state.

Hereinafter, details of embodiments of the rear table according to the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of a seat equipped with a rear table according to the present invention. A seat bag 2 is provided. Armrests 3A and 3B are attached to both sides of the seat bag 2 with their rotational ranges restricted. That is,
These armrests 3A, 3B are arranged to rotate around a support shaft 10 provided on the seat back 2 to the positions shown by solid lines and imaginary lines, respectively. Further, a table 4 is rotatably provided on the back surface 2a of the seat bag 2, and the rotary base end 4a of the table 4 is connected to the armrests 3A, 3B.
The free end 4b of the table 4 is located at the top side of the seat bag 2, and is fixed to the back surface 2a of the seat bag 2 while being positioned at the side. The width of the table 4 is set to be slightly narrower than the facing distance l between the armrests 3A and 3B. This table 4 includes a core material 5 as shown in the second figure, this core material 5 is covered with a trim skin 6, and a flexible tongue piece 7 protruding from this trim skin 6 is fixed to the back surface 2a of the seat back 2. . Hook-and-loop fastener elements 8A and 8B constituting a pair of engaging members that are removably engaged with each other are fixed to the free end 4b of the table 4 and the back surface 2a of the seat bag 2. Also, table 4
A handle belt 9 is fixed to the free end 4b of the handle belt 9, and by pulling the handle belt 9, the surface fastener elements 8A and 8B are separated from each other.
The table 4 is rotated in the direction of arrow A in FIG. 2 with its rotation base end 4a, that is, the tongue piece 7 as a reference. That is, the table 4 is rotated from the position shown by the solid line in FIG. 1 to the position shown by the imaginary line, and is extended horizontally to the rear of the seat bag 2.

Opposed locking holes 23, 23 are formed in the inner wall of each of the armrests 3A, 3B at the distal end thereof. Further, protrusions 24, 24 are provided on the tip sides of both side edges of the table 4, protruding from the both side edges and engaging with the locking holes 23, 23 of the armrests 3A, 3B.
can be moved in and out by operating a knob 25 provided at the center of the table 4 on the side of the free end 4b.

On the other hand, the armrests 3A and 3B are attached to the seat back 2 in the structure shown in the third figure. Since these armrests 3A and 3B are attached to the support shaft 10 in the same manner, one armrest 3A will be representatively illustrated and explained in FIG. 3, and illustration and explanation of the other armrest 3B will be omitted. The support shaft 10 is a seat frame 11 of the seat bag 2.
It is fixed to and protrudes from the side surface 2b of the seat bag 2. An armrest frame 12 of the armrest 3A is rotatably fitted into the protruding end of the support shaft 10. The fitted portion of the armrest frame 12 has an open cylindrical shape as shown in the fourth figure, and the opposing side walls 1 of this fitted portion
3A and 13B, a large diameter through hole 14A and a small diameter through hole 14B are bored coaxially with each other. The large diameter base of the support shaft 10 is located in the large diameter through hole 14A, and the small diameter tip 15 of the support shaft 10 is located in the small diameter through hole 14B. A male thread 16 is carved in the large diameter base of the support shaft 10 adjacent to this small diameter tip 15.
Nut 17 is seated at 6. This nut 17 and the side wall 13 of the armrest frame 12
A compression spring 18 and washer 19 are installed between A and A.
is interposed, and the elastic force of the compression spring 18 normally causes the armrest 3A to lie along the side surface 2B of the seat back 2, and rotates the armrest 3A from the solid line shown in FIG. 1 to the imaginary line shown. When stepping over the table 4, the armrest 3A is moved in the direction of arrow B in FIG. 3 against the elastic force of the compression spring 18. Further, the amount of protrusion of the small diameter tip 15 from the through hole 14B is as follows:
Armrest 3 due to compression of compression spring 18
It is larger than the amount of movement of A in the direction of arrow B.

On the other hand, the range of rotation of the armrests 3A, 3B with respect to the seat back 2 is restricted to a certain range by the following armrest position setting mechanism. In the explanation of this structure as well, armrests 3A and 3B are attached to the support shaft 10 in the same way as described above, so one armrest 3A
will be explained, and the explanation of the other armrest 3B will be omitted. As shown in FIGS. 3 and 5, a stopper 20 is disposed below the support shaft 10 fitted into the armrest 3A, and this stopper 20 is fixed to the seat back frame 11. The stopper 20 projects from the side surface 2b of the seat bag 2, and the projecting end of the stopper 20 is positioned within a semicircular long hole 21 formed in the side wall 13A of the armrest frame 12. Therefore, when the armrest 3A is positioned as shown by the solid line in FIG. 1, one end 22A of the elongated hole 21 comes into contact with the stopper 20, and when the armrest 3A is positioned as shown by the imaginary line in FIG. The other end of the elongated hole 21 is brought into contact with the stopper 20, whereby the armrest 3A is stopped in the state shown by the solid line or the imaginary line in FIG.

In the embodiment configured as above,
To use the rear table, move the armrests 3A and 3B shown in solid lines in Figure 1 to the seat back 2.
Rotate it backwards and position it on the imaginary line. Thereafter, by pulling the belt 9, the hook and loop fastener 8 is
As A and 8B are separated, the table 4 rotates in the direction of arrow A in FIG. 24, 24 as armrest 3
Fit into the locking holes 23, 23 of A and 3B. Thereby, the table 4 is held in a horizontal state behind the seat bag 2 by the armrests 3A, 3B, and can be used. According to this embodiment, by engaging the protrusions 24, 24 of the table 4 with the locking holes 23, 23 of the armrests 3A, 3B, the table 4 can be firmly held in a horizontal state, and vibrations of the vehicle can be avoided. This prevents the table from shaking up and down even when the table is moved.

As explained above, according to the present invention, an armrest position setting mechanism is provided which allows the armrest to be moved or rotated so as to project toward the rear of the seat back portion, and a table having a width slightly narrower than the facing interval of the armrest is provided. , is rotatably provided on the back of the seat back at approximately the same position as the armrest, and the protrusions provided on the tip sides of both side edges of the table are locked into the locking holes provided on the inner walls of each of the armrests. Since the table is held in a horizontal position by the armrest set on the rear side of the seat back part by the armrest position setting mechanism, the table can be held in a horizontal position using the armrest and the locking hole provided in the armrest. It can be held firmly and the table will not shake even due to vehicle vibrations. In addition, there is no need for special support stays as in the conventional case, and the structure around the table and the back of the seat bag can be made simple, so flexibility in use can be ensured.
