Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating seat in a vehicle such as a passenger car.

[0002]

2. Description of the Related Art In a conventional rotary seat of this kind,
The seat body has both a rotation function and a slide function.
That is, the turntable is rotatably supported on a fixed base installed on the floor, and the seat body is slidably supported on the turntable. By making the seat body rotatable and slidable in this way, the seat body can be appropriately rotated or slid at the time of getting on and off, thereby making it easier to get on and off.

[0005] For example, FIG. 5 shows an operation example of a conventional rotating seat. In the figure, first, a seat body 1 includes a seat cushion 2 and a seat back 3, and is rotatable around a rotation center O (see FIG. 5B). Further, it is possible to slide within a slide range S set by the front most position FM and the rear most position RM. When the seat body 1 is slid to the front morning position FM side and further rotated to the side door side when getting on and off, a part of the seat body 1 projects from the opening flange 100 as shown by a dotted line.
In FIG. 5, 101 is an instrument panel, 102 is a rocker outer, 103 is a cowl side trim, and 104 is a pillar garnish.

[0004]

Incidentally, in order to improve the getting on and off after rotation of the seat body 1, it is preferable to increase the sliding amount, that is, to increase the protruding amount L from the rocker outer 102 (see FIG. 1). FIG. 6 (B)). However, if the amount of sliding of the seat body 1 is increased to secure a large amount of protrusion L from the rocker outer 102, in this case, when the seat body 1 is slid to the front morning position FM side, as shown in FIG. gap G knee M ₁ and around the instrument panel 101 of the passenger M is narrowed. For this reason, the space around the feet is narrowed, and it is inevitable to take a cramped posture. In order to avoid this, the slide may be lowered to a position where the posture is not cramped before the rotation, and the slide may be moved forward after the rotation. However, two operations are required, which is troublesome.

For this reason, conventionally, there has been devised a structure in which slide rails having different slide amounts are arranged in a two-stage product, and the slide amount is changed before and after the rotation of the seat. However, in this case, a stopper is required to prevent one of the slide rails from moving before and after the rotation of the seat, which complicates the structure. Further, when the slide rail is a single-stage type, there may be a method of restricting the lock mechanism of the seat adjuster. However, in that case, there is a problem that the structure is complicated.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a rotating seat for an automobile capable of improving the getting on / off property while properly exhibiting its original function.

[0007]

According to the present invention, there is provided a rotating seat for an automobile in which a turntable is rotatably supported on a fixed base, and a seat body is slidably supported on the turntable. A seat, wherein a sliding amount of the seat changes in accordance with a rotation angle of the seat body.

According to the second aspect of the present invention, a stopper member is attached to the seat body, and a slide regulating member is provided at an appropriate position on the fixed base side, and the stopper member regulates the slide at a predetermined rotation angle of the turntable. The sliding amount of the seat body is regulated by contacting the member. According to a third aspect of the present invention, the stopper member comes into contact with the slide regulating member at the first rotation angle of the turntable. According to a fourth aspect of the present invention, there is provided a rotating seat for an automobile, wherein the stopper member does not contact the slide regulating member at the second rotation angle of the turntable.

According to the present invention, when the seat body is slid and rotated at the time of getting on and off, the sliding amount changes according to the rotation angle. That is, before the rotation of the seat body, the stopper member abuts on the slide regulating member at the first rotation angle of the turntable, whereby the sliding amount of the seat body is regulated. At this time, a large space around the feet of the occupant can be secured, and a comfortable posture can be taken. Further, at the second rotation angle of the turntable after the rotation of the seat body, the stopper member does not abut on the slide regulating member. At this time, by increasing the sliding amount of the seat body, it is possible to improve the getting on / off property.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 to 4, the same reference numerals are used for members which are substantially the same as or correspond to those of the conventional example, and a preferred embodiment of a rotating seat for an automobile according to the present invention is described. explain. FIG. 1 shows the main configuration of the rotating seat in this embodiment. In the figure, a seat body 1 includes a seat cushion 2 and a seat back 3. The seat cushion 2 is supported on a pair of slide rails 4 so as to be slidable by a fixed stroke. The seat back 3 is rotatably connected to the seat cushion 2 via a shaft.

The entire seat body 1 is supported on the turntable 5 by fixing the base of the slide rail 4 to the turntable 5. This turntable 5
Is rotatably supported on a fixed base 6 installed on the floor. Thus, in the basic configuration of the rotating seat,
The turntable 5 rotates as shown by the arrow, and the seat body 1 slides back and forth, thus having both a rotation function and a sliding function.

Now, in the present invention, the seat body 1 is rotatably supported on the fixed base 6 as described above.
The slide amount changes according to the rotation angle. Therefore, a stopper member is attached to the seat body 1 and a slide regulating member is provided at an appropriate position on the fixed base 6 side. In this embodiment, a stopper pin 7 as a stopper member is hung below the seat cushion 2, and a slide restricting pipe 8 is provided on the fixed base 6 side.

Here, the turntable 5 is set to be rotatable at a rotation angle θ of about 70 ° in this example. That is, as shown in FIG. 2, the seat body 1 has a first rotation angle disposed along the front-rear direction (arrows F and R directions) and a second rotation angle rotated by an angle θ from the front-rear direction. You can rotate between. Therefore, the seat body 1 rotates between the first rotation angle and the second rotation angle together with the turntable 5.

As shown in FIG. 2, the pipe 8 has one end 8a arranged along the front-rear direction and the other end 8b
Are arranged at an angle θ from the front-back direction. As shown in FIG. 2, the contact portion 8c of the pipe 8 is arranged so as to be deviated forward by a predetermined distance from the rotation center O at the center of the seat. By forming and arranging the pipe 8 in this manner, especially when the seat body 1 is slid forward at the first rotation angle of the turntable 5, the stopper pin 7 comes into contact with the pipe 8 (FIG. 3).
Reference), the slide amount S1 of the seat body ₁ is regulated.

[0015] In the above configuration, the seat body 1 at the time of getting on and off the vehicle.
When sliding and rotating, the sliding amount changes according to the rotation angle. For example, when getting off, the seat body 1
Is slid forward at the first rotation angle, the stopper pin 7 comes into contact with the contact portion 8 c of the pipe 8. At this time,
As shown in FIG. 2, the stopper pin 7 is in the rearmost position RM.
To move from _one to the front-most position FM _1. As described above, since the sliding of the seat body 1 is restricted, FIG.
The gap G between the knee M ₁ and around the instrument panel 101 of the occupant M, as (A) is increased, it is possible to secure a large space around the foot.

Next, when the seat body 1 is rotated toward the side door to the second rotation angle in this state, FIG.
Protrudes from the opening flange 100 as indicated by the dotted line. After this rotation, when the further sliding the seat body 1, the stopper pin 7 can move to the front-most position FM ₂ as shown in FIG. As described above, at the second rotation angle, the seat body 1 as shown by the solid line in FIG.
By increasing the amount of protrusion L from the rocker outer 102, it is possible to improve getting on and off.

[0017]

As described above, according to the present invention, the original function is ensured by optimally adjusting the amount of slide before and after the rotation of the seat in a seat having both this kind of rotation function and slide function. Thus, excellent usability and the like can be realized, and the getting on and off property can be remarkably improved. For example, when the seat is rotated, the space between the occupant and the body (particularly, the instrument panel) is increased, so that a large space around the feet can be ensured. Therefore, it is not necessary to take an unreasonable posture. Further, after the rotation, the seat can be slid with a full stroke, and getting on and off can be facilitated.
