Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seat operating device provided for adjusting the angle of the seat back of a seat installed in a vehicle such as an automobile.

(Prior Art) As a conventional seat operating device, one shown in FIG. 6, for example, is known. (Nitsun Service Bulletin No. 484 “Introduction of Y30 series cars” 1982)
(Published by Nissan Motor Co., Ltd., June 2016; see page 330) This conventional seat operating device B includes a cushion finisher 101 that covers a reclining device 100.
A reclining operation knob 103 was provided at the tip of the reclining lever 102 from 00 in an externally exposed state.

Therefore, when adjusting the angle of the seat back 104, as shown in FIG.
The operator would insert his or her finger from the distance 1 between the two and grasp the reclining operation knob 103, and then pull the operation knob 103 up from the solid line position in FIG. 7 to the imaginary line position.

However, in such conventional device B, it is necessary to provide a distance l for inserting a finger, and furthermore, the reclining operation knob 103 is exposed from the cushion finisher 101. , the lap belt 105 enters under the reclining operation knob 103 as shown by the solid line in FIG.
When removing the seatback or in the event of a collision, lift the reclining operation knob 103 as shown by the imaginary line in FIG.
There were problems such as rubbing and cutting.

Attempts have been made to reduce the catch of the lap belt 105 as much as possible with respect to the conventional device B, and sheet operating devices C shown in FIG. 8 and seat operating devices D shown in FIG. 10 have been proposed. I've reached it.

In both of these conventional devices C and D, a finisher recess 106 is formed in the cushion finisher 101, and reclining operation knobs 103, 107 are arranged in this finisher recess 106. Since the device is not exposed, the wrap belt 105 is less likely to get caught compared to the conventional device B mentioned above.

However, in the case of conventional device C,
As shown in Figure 9, the distance l for inserting the finger
Since it is necessary to remove the belt, the problem of the lap belt 105 getting caught still remains unresolved.

Also, in the other conventional device D, as shown in FIG.
There was a problem in that the lap belt 105 got caught on 7a (projection length l').

(Means for Solving the Problems) That is, the present invention has been made for the purpose of solving the above-mentioned problems, and in order to achieve this purpose, the present invention provides a reclining operation knob for adjusting the angle of the seat back. and a cushion finisher for arranging the reclining operation knob, wherein the reclining operation knob is an annular knob having a finger insertion hole, and a knob side surface of the reclining operation knob. The bottom surface of the knob was brought close to the finisher recess of the cushion finisher.

(Function) Therefore, in the seat operating device of the present invention, by forming the finger insertion hole in the reclining operation knob, there is no need to provide a finger insertion interval between the reclining operation knob and the cushion finisher. Since the side of the knob and the bottom of the knob are placed close to the finisher recess, there is no room for the lap belt to enter.
This eliminates the possibility of the lap belt getting caught on the reclining operation knob or getting caught between the knob and the finisher.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
In describing this embodiment, a seat operating device for an automobile seat will be taken as an example.

First, the configuration of the embodiment shown in FIGS. 1 to 3 will be explained.

Reference numeral 1 denotes an automobile seat consisting of a seat cushion 2 and a seat back 3. The seat back 3 is connected to the seat cushion 2 via a reclining device 4 whose inclination angle can be adjusted.

Reference numeral 5 denotes a reclining operation knob, which is provided at the tip 6a of the reclining lever 6 extending from the reclining device 4, and is used when adjusting the angle of the seat back 3.
The reclining operation knob 5 is a ring-shaped knob in which an inverted trapezoidal finger insertion hole 7 is formed.

The reclining operation knob 5 of the embodiment is made by pouring melted synthetic resin into the tip 6a of the reclining lever 6 and molding it integrally with the lever.The specific shape of the knob is an inverted base having a certain thickness. The shape is such that an inverted trapezoidal finger insertion hole 7 is hollowed out from the center to the lower part of the plate, leaving only the annular outer periphery.

Furthermore, all corners of the reclining operation knob 5 are rounded in consideration of grip comfort and catching during operation.

Reference numeral 8 denotes a cushion finisher which covers the reclining device 4, arranges the reclining operation knob 5, and provides seat-related switches, etc., and which controls the reclining operation of the cushion finisher 8. knob 5
A finisher recess 9 is formed inwardly from the finisher side surface 8a and the finisher upper surface 8b.

The arrangement of the reclining operation knob 5 with respect to the finisher recess 9 is as follows:
The gap t between a and the front inner surface 9a, the rear knob side surface 5b and the rear inner surface 9b, and the knob bottom surface 5c and the recess bottom surface 9c.
1, t2, and t3 are arranged close enough to absorb mounting dimensional errors.

In addition, the outer surface 5d of the reclining operation knob 5
do not protrude from the finisher side surface 8a of the cushion finisher 8, but are substantially flush with each other (slightly recessed).

Further, a space 10 is formed between the reclining operation knob 5 and the seat-side inner surface 9d of the finisher recess 9, which is large enough to fit a finger.

Note that the reference numeral 11 in the figure is a finisher notch, which is cut out for rotating the reclining operation knob 5.

Next, the operation of the embodiment will be explained.

First, when performing the reclining operation,
As shown in the figure, the lock of the reclining device 4 is released by inserting a finger f into the finger insertion hole 7 of the reclining operation knob 5, grasping the reclining operation knob 5, and pulling it upward.
The inclination angle of the seat back 3 can be adjusted as desired,
After adjustment, the reclining operation knob 5 is returned to its original position to lock it in the adjusted position and the reclining operation can be performed.

When sitting on the seat 1 using the seat belt 12, the lap belt 12a (waist belt) and shoulder belt 12b are pulled out and inserted into the locking member 13 on the vehicle body side and fixed. In this case, as shown in FIGS. 4 and 5, the lap belt 12a comes into contact with the upper surface of the reclining operation knob 5, etc.

As described above, since the reclining operation knob 5 has interference contact with the lap belt 12a, conventionally the lap belt 12a has been caught on the knob, but in the seat operating device of the embodiment, the reclining operation By forming the finger insertion hole 7 in the knob 5, there is no need to provide a gap between the finger insertion hole 7 and the cushion finisher 8, and moreover, the knob side surfaces 5a, 5b and the knob bottom surface 5c of the reclining operation knob 5 can be inserted into the cushion finisher 8. Since it is placed close to the recess 9, there is no room for the lap belt 12a to enter, and the lap belt 12a may get caught on the reclining operation knob 5, or the cushion finisher 8 may become attached to the reclining operation knob 5. There is no need to get caught in between.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, the specific shape of the reclining operation knob may be a shape that is somewhat modified from the shape of the embodiment.

(Effects of the Invention) As described above, according to the seat operating device of the present invention, it is possible to prevent the seat belt from getting caught on the reclining operating knob.

In addition, the seatbelt's anti-snapping effect prevents the seatback from falling down suddenly when the seatbelt lifts the reclining control knob when removing the seatbelt or in the event of a collision. It also prevents the seat belt from rubbing against the reclining lever and breaking.
