Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a vehicle seat whose direction can be switched back and forth.

[Prior Art] In one-box type automobiles, etc., that can accommodate a large number of passengers, it may be desirable to use some seats face-to-face depending on the atmosphere inside the vehicle and the usage pattern. Various types of vehicle seat devices have been proposed in the past.

FIGS. 6 (a) and 6 (b) schematically show an example of such a vehicle seat device. This seat device is a bench seat type, and includes a first seat 51 and a second seat 5
2 are arranged side by side in the left-right direction. Further, the seats 51, 52 have seat cushions 51a,
52 a and seat backs 51 b and 52 b, and an armrest 53 is attached to one side of the second seat 52. The armrest 53 is fixed to the seat cushion 52a and is not structured so that it can be easily attached and detached.

Then, in this seat device, the second seat 52 can be rotated, and by this rotation, the front-back direction of the second seat 52 is changed to the sixth direction.
The forward facing state shown in FIG. 6A can be switched to the backward facing state shown in FIG. 6B.

[Problems to be Solved by the Invention] However, in the above-described conventional seat device, since the armrest 53 provided on the second seat 52 is fixed to one side of the second seat 52, the occupant has his arms only there. There was a problem that I could not put.

Also, in order to prevent the armrest 53 from interfering with the first seat 51 when rotating, the first seat 5
Since the distance between the first seat 52 and the second seat 52 must be set large, a large gap B is formed between the first seat 51 and the second seat 52, and when the seats are fully seated, the gap B is the bottom. There was a problem that it became uncomfortable to sit down. In addition, there is a problem that the seat width dimension in the determined vehicle interior space becomes narrower and the sitting comfort is further reduced.

The present invention has been made in view of the above problems, and an object thereof is to provide a vehicle seat having a structure capable of improving the sitting comfort.

[Means for Solving the Problems] In order to achieve the above object, the present invention is a vehicle seat that can be rotated to switch the direction between front and back, and is positionally adjusted in the front-rear direction on a base and an upper portion of the base. An arm rest that is attached so that the base portion includes an armrest that is detachable from the seat portion, and attachment portions that detachably support the armrest are provided on both left and right side portions of the seat portion. It is provided.

[Operation] According to this configuration, when the seat is rotated, the armrest can be removed and rotated, so that it is possible to prevent the armrest from interfering with other objects such as an adjacent seat when the seat rotates. . Further, since the armrest can be detached and rotated, the gap formed between the adjacent seat can be narrowed.

Furthermore, since the position of the arm rest can be adjusted in the front-rear direction, it is possible to move the arm rest to a position according to the occupant's preference, such as after adjusting the reclining of the seat back.

In addition, mounting parts for detachably supporting the armrest are provided on both left and right sides, so you can select this mounting part and replace the armrest on either the left or right side according to the occupant's preference, and it is necessary. You can also use it by attaching armrests on both the left and right sides.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings.

1 to 3 show an embodiment of a vehicle seat device to which the present invention is applied.

In the figure, this seat device 1 is of a bench seat type, and is provided with a first seat 2 and a second seat 3 arranged in a row in the left-right direction. Of these, the first seat 2 is rotatably provided and the armrest 5 is attached.

Next, the seat device 1 will be described in more detail with reference to FIG.
Seats 2 and 3 are seat cushions 6 and 31, respectively.
And seat backs 7 and 32.

Of these, mounting portions 8 are formed on both left and right side surfaces of a seat cushion 6 as a seat portion. Two upper and lower engaging holes 9 are provided on the front surface of the attaching portion 8, and the armrest 5 can be detachably attached through the engaging holes 9.

On the other hand, the armrest 5 includes a flat block-shaped base portion 5a and an arm rest portion 5b mounted on the base portion 5a, and a pair of rails is provided between the base portion 5a and the arm rest portion 5b. The members 13 and 14 are interposed.
The rail members 13 and 14 are dovetail-engaged with each other and are slidable only in the front-rear direction, and at the end 13a side of the rail member 13, the rail member 13
Is removable from the rail member 14. Further, the four engaging holes 15a, 15b, 15 are provided on the upper surfaces of the rail members 13, 14 in a state of being scattered at equal intervals in the front-rear direction.
c and 15d are provided. On the other hand, on the rail member 14 side, two protrusions 16a and 16b are formed corresponding to the engagement holes 15a, 15b, 15c and 15d. When the rail member 13 is slid with respect to the rail member 14 while the rail members 13 and 14 are engaged with each other, the protrusions 16a and 16b correspond to the engagement holes 15a, 15b, 15c, and 15d. The corresponding engaging holes (15a, 15b, 15c, 15d) for each
It falls into the interior and is locked by the detent, and this locking gives a click feeling. Note that FIG. 4 shows a state in which the protrusions 16a and 16b are locked in the engagement holes 15b and 15c, and as can be seen from this figure, the rail member 13 is fixed to the lower surface side of the arm rest 5b, Rail member 14
Are fixedly provided on the upper surface side of the base member 5a. Here, a pair of insertion rods 10 protruding inward are provided on one surface side of the base portion 5b, and the insertion rods 10 can be inserted and engaged in the engagement holes 9, respectively. On the other hand, the arm rest portion 5b is formed in an elongated shape by covering the circumference of the cushion material 11 with the skin material 12, and the vibrator 1 is provided at the tip portion thereof.
7 is built in, and can be started and stopped from outside via a switch (not shown).

The armrest 5 has a pair of corresponding engagement holes 9
It is locked when the insertion rod 10 of the base portion 5b is inserted to a predetermined position, and conversely, when the insertion rod 10 is strongly pulled from this state to the front side, the locking is released and it can be removed. Further, when the arm rest 5b is strongly pushed forward or backward between the arm rest 5b of the base 5a and the arm rest 5b, the rail member 13 and the rail member 14 slide, and the slide causes the base 5a to move. The position of the arm rest 5b with respect to the front-back direction can be adjusted.
It is in a state in which b can be held at each position where it is detent-locked in the engagement holes (15a, 15b, 15c, 15d). Also, one end 13a of the rail member 13
When the arm rest 5b is moved to a position where the portion is separated from the rail member 14, the arm rest 5b can be removed from the base 5a. Then, when the vibrator 17 in the arm rest 5b is activated in this detached state and the arm rest 5b is applied to a desired position on the body, the position can be massaged. In FIG. 3, the armrest 5 is attached to the mounting portion 8
It is shown that the arm rest portion 5b is further removed and the arm rest portion 5b is further removed from the base portion 5a.

Therefore, in the vehicle seat device configured as described above, the first seat 2 is rotated and the first seat 2 is rotated.
When changing the front-back direction of the
The insertion rod 10 is pulled out from the armrest 5, the armrest 5 is removed, and the armrest 5 is rotated in this state. Then, the armrest 5 can be rotated without interfering with other objects. As a result, a large sheet width can be secured for each of the sheets 2 and 3, and a gap A between the sheets 2 and 3 can be secured.
Can be reduced. Furthermore, after the orientation is changed, the armrest 5 can be attached to the attachment portion 8 to be used as an armrest. In this case, the seats can be mounted on either the left or right side of each seat 2, 4 according to the occupant's preference. That is, the second
The figure shows the state after the orientation of the third sheet 4 is changed in this way.

If the position of the arm rest 5b does not match the occupant after the seat back 7 is adjusted for reclining,
By adjusting the position of the arm rest 5b by moving it back and forth, it is possible to eliminate the discomfort. In addition, if necessary, another armrest 5 can be borrowed from another seat and attached to the left and right sides. Furthermore, when the arm rest 5b of the armrest 5 is removed and the vibrator 17 is activated, it can be used alone as a vibrator.

Although the present invention has been described with reference to the above embodiment, it is needless to say that the present invention is not limited to the structure of this embodiment. For example, in the above embodiment, the second seat 3 has a structure that does not rotate, but the second seat 3 may also rotate in the same manner so that the front-back direction can be changed. Further, the vibrator 17 does not necessarily have to be built in the armrest 5, and the arm rest 5b need not be removable as long as it can move in the front-rear direction.

[Advantages of the Invention] As described above, according to the vehicle seat of the present invention, when the seat is rotated, the armrest can be removed and rotated. You can eliminate the interference with other things. Further, since the armrest can be detached and rotated, the gap formed between the adjacent seat can be narrowed. As a result, the seat width can be increased and the sitting comfort is improved.

Furthermore, since the arm rest can be adjusted in the front-back direction, you can move the arm rest to a position according to the occupant's taste, such as after adjusting the reclining of the seat back, so there is no discomfort. The sitting comfort is further improved.

In addition, mounting parts for detachably supporting the armrest are provided on both left and right sides, so you can select this mounting part and replace the armrest on either the left or right side according to the occupant's preference, and it is necessary. As you can also use it by attaching armrests on both left and right sides,
