Description

[Detailed Description of the Invention] The present invention is a mounting device for a table that is attached to a vehicle seat (reclining seat) such as an automobile. Specifically, there is a table storage part provided on the back of the seat bag, a table board stored in the table storage part and having long guide grooves on the left and right end surfaces, and guide grooves of the table board provided on the left and right sides of the opening of the table storage part. The present invention relates to an improvement in a table mounting device comprising a support member that is engaged with the inside of the table and slidably and rotatably supports a table board.

A conventional table mounting device of this type is disclosed in Japanese Unexamined Patent Publication No. 164533/1983.

This is a structure in which the table board is moved in and out of the groove provided on the back of the seat bag, so there are no support legs between the table board and the back of the seat bag.
There is an advantage that the user's feet do not come into contact with the support legs when using the table board, and the movement of the user's feet is not restricted by the support legs.

However, with such a structure, the table board must be adjusted to be horizontal each time the seat bag is pushed back, and it is difficult to maintain the table board in a completely horizontal state. The edges are formed in the first and second guide grooves having a plurality of notches and steps provided on the seat back side, and the first and second guide grooves provided on the table board side.
This is because the table board is adjusted to a substantially horizontal state by engaging the second pin, and the first and second guide grooves are not formed steplessly.

Therefore, in this invention, when the seat back is tilted,
Without adjusting the table board to a horizontal position,
The purpose is to automatically maintain a horizontal state.

Therefore, the table mounting device for a vehicle seat according to the present invention connects and fixes one end of the table board and the cushion frame with a flexible connecting member, and fixes the top and bottom of the connecting member when the connecting member is in an extended state. The support member and the hinge portion of the back frame have a parallelogram structure. Therefore, even if the seat back is tilted, the table board always maintains a horizontal state, so unlike the conventional product, there is no need for adjustment operations, and moreover, the table board remains completely horizontal.

An embodiment of the present invention will be described below with reference to the drawings. In the drawing, A is a seat back which is tiltably connected to a seat cushion frame B by a reclining adjuster (not shown). A table board storage section A is provided. This table board storage part A is formed by a housing 40 with one side open, which is embedded and fixed in the seat bag A, and supporting members 20, which will be described later, 20 are provided so as to protrude and face each other inwardly. And left and right side plates 40
In a, an arc-shaped rotary slot 42 centered on the support member 20 and a straight long slot 43 connected below the lower end of the rotary slot 42 are formed at opposing positions.

Furthermore, a fixing magnet 44 is attached to the upper edge of the opening 41.
is provided so that a suction plate 12 provided on the end surface of the table board 10, which will be described later, can be suctioned.

10 in the figure is a flat table board having a picture frame 13 along its periphery;
A space 14 for fitting the support member 20 is provided between them, and long guide grooves 11, 11 are bored in the frame 13a, 13a on both left and right end surfaces, and the support member 20 is inserted into the left and right guide grooves 11, 11. are fitted so that the table board 10 can slide and rotate along the long guide grooves 11, 11. Further, the rotation slot 42 is provided at one end of both the left and right end surfaces of the table board 10.
Fixing pins 15, 15 inserted through the long slot holes 43 are fixed (FIG. 4) to hold the table board 10 in a predetermined position. That is, when the table board 10 is in use (FIGS. 1 and 2), the fixing pin 15 is locked in the rotation slot 42 by the connecting member 30, which will be described later, so that the table board 10 does not move downward. The movement in the protrusion direction is restricted. Since the fixing pin 15 is located at the lower end of the long groove hole 43 when the table board 10 is in the stored state, the movement of the lower part of the table board 10 in the front-rear direction is restricted. In the figure, 16 is a handle.

One end of a flexible connecting member 30 such as a wire or string is fixed to the tip of the fixing pin 15 described above.
At the other end of the connecting member 30, there is a seat cushion B.
Fix it to the seat frame b. That is, the wire connecting member 30 connecting the back frame a hinge part a' of the seat back A and the mounting part of the support member 20 is parallel, and the distance between the fixing pin 15 and the connecting member 30 and the distance between the hinge part a' and the connecting member 30 are The seat frame b is formed into a parallelogram structure with the same distance from the fixed part, so that even if the seat back A is tilted, the table board 10 always maintains a horizontal state (Figs. 2 and 6).
figure).

The support member 20 in the figure has its head connected to the table board 1.
Bolt 21 inserted into the long guide grooves 11, 11 of 0
, nuts 22 that fix this bolt 21 to the left and right side plates 40a of the housing 40, and the table board 10.
Return spring 24 with a roll 23 that urges the fixing pin 15 toward the upper end of the rotation slot 42
The table board 10 is slidably and rotatably supported (see Figs. 3 and 5).
figure). In the figure, 25 indicates a color. Therefore, when the table board 10 is lifted upward against the elastic force of the return spring 24, the fixing pin 15 of the table board 10 moves into the rotation slot 42 using the support member 20 as a fulcrum.
It descends along the inside of the long groove hole 43. As the fixing pin 15 descends, the table board 10 is stored in the table board storage part A (FIG. 7).
Since the suction plate 12 is attracted to the magnet 44 in the stored state, the upper part of the table board 10 is stored without wobbling.

Next, to explain how to take out the table board 10 from the stored state and use it, first, when the table board 10 is pulled upwards by the handle 16, the fixing pin 15 of the table board 10 rises along the long slot hole 43 and rotates. It enters into the slot 42, and the table board 10 rotates accordingly (FIG. 7). Note that the arrows in FIG. 7 indicate the operating range of the table board 10 before and after use. Then, with the fixing pin 15 tensioned by the connecting member 30, the table board 10 is placed in a horizontal operating state, and this state is maintained by the elastic force of the return spring 24 with a roll (see Fig. 6). ). When the table board 10 is in use, the back surface of the seat bag B has a concave shape due to the table board storage part A, so that the user's legs can be inserted into the part A.

Although not shown in the drawings, if an opening is provided in only a part of the casing 40 forming the table board storage part A, and the other part is covered with a seat cover or the like, the table board 10
In the stored state, only the opening and one end surface of the table board 10 stored inside the opening can be seen from the outside, so it is possible to provide a seat bag with excellent aesthetic appearance.

Since the present invention is constructed as described above, it has the following advantages over the conventional products.

(1) The flexible connecting material that connects the table board and the seat frame of the seat cushion becomes tense when the table board is removed from the storage section.
It becomes parallel to the back frame of the seat back, forming a parallelogram structure. Therefore, even if the inclination angle of the seat back changes, the table board remains parallel to the vehicle floor and remains horizontal.
Therefore, there is no need to adjust the table board to a substantially horizontal state each time the seat back is tilted, unlike the conventional product.

(2) Also, since the present invention has the above-mentioned structure, the table board can be held in a completely horizontal state, but even if the conventional product is adjusted, the adjustment structure is stepped, so the table board cannot be held in a completely horizontal state. difficult to maintain.
