Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a structure for fixing a lock knob in an automobile interior part.

<<Prior Art>> Among vehicle seats, peripheral parts thereof, and other automotive interior parts, those having movable parts are
A functional component is provided inside, and an operating rod of the functional component is coupled to a knob that penetrates through the pad and the skin material and projects onto the surface of the skin material.

[Problems to be solved by the invention] Conventional knobs of this type are provided so that they can be exposed and retracted through a grommet (also called an escutcheon) that is fitted and fixed into an opening in the skin material, but the arrangement of the grommet and the knob is Due to the relationship between the centering rod and the operating rod, precision is required for centering work, and assembly is troublesome, resulting in high costs. In addition, if the knob is improperly placed, the knob will hit the grommet unevenly, reducing operability and making the interior visible, resulting in an unsightly appearance.

Therefore, the purpose of this invention is to eliminate the lock knob, increase dimensional tolerance during positioning, improve assembly workability, and further improve operability and appearance.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention provides an automobile interior part in which a push-type operation knob is protruded from the surface of the skin material and a functional part interlocked with the operation knob is provided inside the skin material. In the above, the operating knob has a head portion continuously formed at one end of a back engaging portion into which the operating lever of the functional component is inserted, and a flange portion continuously formed at the other end, and the back engaging portion is formed of a skin material. The operating knob is inserted into a mounting hole provided in the flange, and the operating knob is fixed to the skin material by sandwiching the skin material between the head and the flange directly or with a back plate interposed therebetween.

According to the above configuration, the knob can be operated with the skin material and pad expanded and contracted.

<<Example>> Hereinafter, an example of this invention will be described in detail using the drawings.

FIG. 1 shows a rotating armrest to which this invention is applied.

In the figure, 1 is a frame that is rotatably supported via a pin 2, 3 is a ratchet wheel fixed to the outer periphery of the pin 2, and 4 is a frame that is pivotably supported to the frame 1 via a pin 1a. , and one end thereof is a pawl that engages with the ratchet wheel 3, and the other end of the pawl 4 is connected to one end of an operating lever 6 via a connecting pin 5, and functions with the ratchet wheel 3, pawl 4, or the operating lever 6, etc. Consists of parts.

The other end of the operating lever 6 passes through the tip of the frame 1 and projects.

The outer periphery of the frame 1 is a pad 7 and a skin material 8.
The other end of the operating lever 6 protruding from the frame 1 is inserted into a through hole 9 formed in the pad 7, and is also inserted into a hole-shaped back engaging portion 10a of the lock knob 10. The lock knob 10
a head 10b at one end of the back surface engaging portion 10a;
A flange portion 10c is continuously formed at the other end, and the back surface engaging portion 10a is inserted into a mounting hole 8a provided in the skin material 8, and the head portion 10b and the flange portion 10c are connected to each other. It is fixed to the skin material 8 by sandwiching the skin material 8 therebetween. Therefore,
The head 10b of the lock knob 10 protrudes from the surface of the skin material 8.

The pawl 4 is always connected to the pawl wheel 3 by a coiled spring (not shown) or the like.
Therefore, the lock knob 10 is urged toward the projecting side through the operation lever 6.

To change the inclination angle of the armrest from the illustrated state, push the lock knob 10 to elastically deform the cover material 8 and pad 7 and push the operating lever 6. This causes the pawl 4 to separate from the ratchet wheel 3. The armrest can be rotated.

Next, when the lock knob 10 is released, the knob 10 will protrude again together with the cover material 8, and the armrest can be fixed at any inclination angle depending on the position of the teeth of the ratchet wheel 3.

FIG. 2 shows another example of the lock knob, in which the lock knob 20 has a hole-shaped back engaging portion 20.
Attach the other end of the operating lever 6 to a and insert it into the mounting hole 8a of the skin material 8, and secure the skin material 8 to the skin material 8 by sandwiching the skin material 8 between the head 20b and the flange portion 20c. This is the same as the embodiment shown in FIG. There is.

In the above embodiment, the present invention was applied to a rotary armrest, but it can also be applied to, for example, a movable headrest or other general automobile interior parts equipped with a push-type knob.

<<Effects of the invention>> As explained above, in this invention, compared to the conventional method in which the operation knob is provided so as to be retractable through the grommet that is fitted and fixed in the opening of the skin material, the grommet is I don't need it at all, so
The number of parts can be reduced, and troublesome positioning is no longer necessary. In addition, the operation knob is fixed to the skin material by simply sandwiching the skin material between its head and flange, making assembly easy. It is easy to make and therefore low cost, and the interior of the frame housing the functional parts is completely covered, improving the appearance.
