Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rear seat reclining device in which an operating knob of an operating lever is disposed at the lower end of the backrest of an automobile rear seat.

(Prior Art) Conventionally, there are rear seat reclining devices as shown in FIGS. 3 and 4, for example.

That is, a large opening 5 is formed at the lower end of the backrest 41 of the rear seat 4, and the operating lever 6 of the reclining device is pivoted near the middle between the backrest 41 and the seat 42, and the operating knob 60 is opened. The operating lever 6 is positioned so that it does not protrude from the portion 5 toward the seat surface side of the rear seat 4, and the operating knob 60 is grasped to move the operating lever 6 to the lock position shown by the solid line in FIG. 4 and to the lock position shown by the chain line in FIG. It is possible to swing the lever 6 vertically between the unlocked position and the unlocked position shown by .
The angle of inclination of the backrest 41 relative to the seat portion 42 can be adjusted.

In addition, as another conventional example, for example, a long hole extending in the vertical direction is provided at the lower end of the backrest of the rear seat.
An operating lever pivotally supported near the middle between the backrest and the seat of the rear seat is projected from the elongated hole toward the seat surface of the rear seat, and an operating knob is fixed to the tip of the operating lever, and the operating knob is gripped. The operating lever is made vertically swingable along the elongated hole between a lock position and an unlock position.

(Problem to be Solved by the Invention) However, in the first conventional example described above, the operating knob 60 does not protrude toward the seat surface side of the rear seat 4, so the operating knob 60 does not interfere with the seated person. The opening 5 must be made large enough to allow the operating knob 60 to be grasped and the operating lever 6 to be swung between the locking position and the unlocking position. It is quite large, and as shown in FIG. 3, the operating knob 60 and its surroundings can be seen through the opening 5, resulting in an extremely poor appearance.

In addition, in the above-mentioned other conventional examples, since the operating knob always protrudes toward the seat surface of the rear seat, the operating knob gets in the way of the person sitting on the seat, and there is a problem in that the seat is uncomfortable.

The present invention was developed by focusing on these problems.The opening at the lower end of the backrest is made smaller to improve the appearance, and when in the lock position, the operating knob of the operating lever is To provide a reclining device for a rear seat in which an operation knob is made substantially smooth with the seat surface of a backrest so that it does not interfere with a seated person.

(Structure of the invention) The gist of the invention is to provide a rear seat reclining device in which an operating lever is passed through the lower end of the backrest of the rear seat from the rear, and an operating knob is disposed at the tip of the operating lever. is pivotally supported on the back of the back rest, and the operating lever is provided with a first lever part extending in a radial direction with respect to the pivot axis of the lever, and a first lever part extending in a circumferential direction with respect to the pivot axis from the lower end of the first lever part. or a second lever portion extending in a tangential direction, an opening small enough to allow insertion of the second lever portion is provided at the lower end of the back rest, and the operating knob protrudes from the opening. The operating lever is swingably supported so as to be reversed between an unlocked position and a locked position in which the operating knob hides the opening and is substantially smooth with the seat surface of the back rest. The invention consists in a rear seat reclining device.

(Function of the invention) In the rear seat reclining device, the second lever portion extends in the circumferential direction or tangential direction with respect to the pivot axis of the operating lever, so that when the operating lever swings, The second lever portion moves in and out of the opening without substantially vertically displacing the opening, and when the operating lever is in a locked position, the operating knob hides the opening; The operating knob is substantially smooth with the seat surface of the back rest.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 and 2 show an embodiment of the present invention, in which a backrest 1 for a seat 11 of a rear seat 1 is shown.
An operating lever 2 for a reclining operation (not shown) for adjusting the inclination angle of the seat back 12 is pivotally supported by a pivot 20 at the back of the back rest 12 .

The operating lever 2 includes a first lever portion 21 extending in a radial direction with respect to the pivot shaft 20, and a first lever portion 21 extending in a radial direction with respect to the pivot shaft 20.
The second lever part 22 extends from the lower end of the pivot shaft 20 in the circumferential direction or tangential direction with respect to the pivot shaft 20, and the operating knob 23 is fixed to the tip of the second lever part 22.

A small opening 3 is formed at the lower end of the backrest 12, through which the second lever portion 22 is inserted and where the operating knob 23 is accommodated.

The operating lever 2 also has an unlocked position (the position indicated by the chain line in FIG. 1) where the operating knob 23 protrudes from the opening 3 toward the seat surface, and an unlocked position where the operating knob 23 is housed in the opening 3 and is hidden. The end surface 23a of the operating knob 23 can swing between a locking position (the position shown by the solid line in FIG. 1 and the position shown in FIG. 2) where the end surface 23a of the operating knob 23 is substantially smooth against the seat surface 12a of the back rest 12.

In the rear seat reclining device having the above configuration, when the operating lever 2 is in the lock position, the end surface 23a of the operating knob 23 is substantially smooth with the seat surface 12a of the backrest 12, so that the operating knob 23 is seated. Don't get in the way of people.

In this locked position, insert your hand into the gap 30 below the operating knob 23 and hold the operating knob 23;
By pulling the lever 2, the operating lever 2 can be swung around the pivot 20 toward the unlocked position.

In this unlocked position, the angle of inclination of the backrest 12 relative to the seat portion 11 of the rear seat 1 can be freely adjusted.

After adjusting the tilting angle of the backrest 12, turn the operation knob 2.
3 from the unlocked position shown by the chain line in Figure 1.
By pushing the lever to the lock position shown by the solid line in the figure, the operating lever 2 returns to the lock position.

(Effect of the invention) According to the rear seat reclining device according to the invention, the second lever portion of the operating lever inserted into the opening extends in the circumferential direction or tangential direction with respect to the pivot of the operating lever. When the operation lever swings between the lock position and the unlock position, the second lever part hardly displaces in the vertical direction with respect to the opening, so the size of the opening is controlled by the second lever part. The operating knob can be inserted and made small enough to be stored, improving the appearance, and in the locked position, the operating knob is almost smooth with the back seat surface, so the operating knob does not get in the way of the seated person. It won't happen.
