Description

[Detailed description of the invention] [Field of industrial application] This invention is a vehicle seat equipped with a vibrator that can apply vibrations to specific parts of the seat such as the back and lumbar region of the person sitting on the seat. Regarding equipment.

[Prior Art] In vehicles such as cars, people often sit in the same posture, which causes fatigue in the back and lower back.

Therefore, conventionally, for example, Japanese Patent Application Laid-open No. 60-48748,
As exemplified in Japanese Unexamined Patent Publication No. 58-118756, it is known that a vibrator is built into a vehicle seat so that it can be used as needed.

In these conventional structures, the vibrator is fixed to an S spring that elastically holds the pad material from the back side of the vibrator, and the vibrations generated by the vibrator are transferred from the S spring to the pad material and then to the pad material. Vibrations are applied to the seated person via the skin material covering this pad material.

[Problems to be solved by the invention] Therefore, in the above conventional structure, the vibrator is fixed to the S spring arranged on the back side of the pad material, so the vibrations caused by the vibrator are transmitted to the entire pad material and are weakened through the pad material. vibration is applied to the entire holding part of the seater. In other words, even if the vibration characteristics of the vibrator itself are improved, the vibrations are weakened by the pad material, which is elastic and has excellent vibration absorption properties, and moreover, the vibrations are weakened by the pad material, which is elastic and has excellent vibration absorption properties.In addition, it is difficult to provide effective pine surge by applying large local vibrations to the seater. It was impossible.

As a solution to this problem, it is also being considered to incorporate a flat diaphragm into the seat back and directly apply vibrations from the diaphragm to the seated occupant through the skin material. . However, with this diaphragm structure, the diaphragm hits the seated person in a flat manner, and vibrations are applied to the entire area of contact, so that the vibrations received by the seated person are felt to be weak in this case as well. Moreover, since a relatively hard flat diaphragm comes into contact with the seat, there is a problem that the cushioning properties of the seat itself are impaired.

Therefore, the present invention was devised to eliminate the problems of the conventional structure as described above.The purpose of this invention is to improve the pine surge effect by applying vibration locally by the vibrator, and to improve the cushioning properties. An object of the present invention is to provide a vehicle seat device equipped with a vibrator having a structure capable of suppressing the deterioration.

[Means for Solving the Problem] In order to achieve the above object, the vehicle seat device with a vibrator according to the present invention includes a frame and a pad material held by a plurality of S springs provided using the frame. Along with covering with skin material,
In a vehicle seat device with a built-in vibrator, the vibrator is fixed to the frame and is provided with a vibration transmitting device that is closely disposed along the back side of the skin material within a through hole provided in the pad material. The seat is connected to a coil spring, and vibrations are applied from the coil spring to the seated person through the skin material.

[Function] According to the above configuration, the sitting person receives the vibration of the vibrator locally through the coil spring that is closely placed on the back surface of the skin material, so the vibration in the part of the body that corresponds to the coil spring is strongly suppressed. Feeling,
Pine surge effect is strengthened. In addition, the coil spring itself flexes according to the shape of the body, improving adhesion and also serving as a cushion, so that deterioration in cushioning performance can be suppressed.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 to 3 show the structure of a vehicle seat device equipped with a vibrator according to the present invention.

In the figure, a seat 1 includes a seat cushion part 2 and a seat back part 3, and
It has a general configuration in which a headrest 4 is attached to the upper part of a seat back part 3.

More specifically, the seat back part 3 has a back frame 6 fixed to the seat cushion part 2 via a reclining device 5 attached to a frame (not shown) of the seat cushion part 2.
It is composed of a wire 7, an S spring 8, a pad material 9, a skin material 10, a vibration transmission coil spring 11, a vibrator 12, and the like.

The wire 7 is bent into a rectangular shape and is further attached to the back frame 6 via a bracket 13 or the like. Also wire 7
One end of each of the plurality of S springs 8 is fixed to the left and right sides of the seat back part 3 via the fasteners 14, and by this fixing, each S spring 8 is attached in a lying state on both the left and right sides of the seat back part 3. There is.

The vibrator 12 is fixed to the back frame 6, and starting and stopping are controlled by a switch (not shown).

The coil spring 11 has one end hooked to a bracket 15 fixed to the back frame 6, and the other end fixed to a vibrator 12, so as to extend to the left and right of the seat back part 3. When the vibrator 12 is vibrated, the vibration force of the vibrator 12 causes the coil spring 11 to vibrate left and right.

The pad material 9 is foam-molded with foamed urethane resin or the like, and as shown as a single item in FIG. A hole 9b and a hole 9c for allowing the stay 4a of the headrest 4 to escape are integrally provided. The outer surface of this pad material 9 is covered with a skin material 10, and a coil spring 1 is provided inside the through hole 9a.
1 is attached to the back frame 6.

The skin material 10 has a wadding in the middle, a wading cover on the bottom surface, and a skin covering the top surface of the wadding. In addition, the portion of the pad material 9 corresponding to the through hole 9a is connected to the seat back portion 3 as shown in FIG.
The inner side of the cushion is pulled by a plurality of cushion springs 16, and this pulling creates a wavy state. Each of the cushion springs 16 is provided between the pitches of the coil springs 11, and the hook portion 16a at one end is connected to the skin material 10.
The hook portion 16b on the other end side is attached to the back frame 6.
The wires 17 are fixed to the wires 17, respectively. And this cushion spring 1
6, each coil spring diameter portion 11a of the coil spring 11 is placed within the wavy portion 10a of the skin material 10.
As a result, the portion 10a of the skin material 10 and the coil spring 11 are brought into close contact, the vibration of the coil spring 11 applied from the vibrator 12 is well transmitted to the skin material 10, and the coil spring 11 and the portion 10a are brought into close contact with each other. are now in a state where they can vibrate as one.

Therefore, in the seat 1 constructed as in this embodiment, when a person sits on the seat cushion section 2 and leans against the seat back section 3 while the vibrator 12 is activated, the coil spring is released through the skin material 10. The vibrations of 11 are transmitted to the back, etc., and this allows you to receive a pine surge. In this structure, coil spring 1
Since the vibration is locally applied only to the portion that is in contact with the coil spring diameter portion 11a of No. 1, the vibration is felt more strongly in the portion where the vibration is applied. Further, when the seated person leans on the coil spring 11, the coil spring 11 is bent and deformed along the body shape of the seated person, so that the coil spring 11 is brought into close contact with the seated person. This can enhance the pine surge effect.
Furthermore, when the coil spring 11 is subjected to an external force, it undergoes elastic deformation and bends, so this coil spring 11 produces cushioning properties similar to the S spring 8, and suppresses a decrease in cushioning properties due to the provision of the vibrator 12. I can do it.

In addition, although the above embodiment discloses a structure applied to a separate type vehicle seat, it may also be applied to a bench seat type, and it is not limited to the seat back portion side, but may be applied to the structure of the seat cushion portion side. is also good. Furthermore, it goes without saying that the present invention is not limited to the above embodiments and may be modified in various ways without departing from the gist of the present invention.

[Effects of the invention] As explained above, according to the vehicle seat device with a vibrator according to the invention, in contrast to the conventional structure, the seater can transmit the vibrations of the vibrator to the vibration transmitting coil closely arranged on the back surface of the upholstery. Since the vibration is received through the spring, the vibration of the portion corresponding to the coil spring is felt locally and strongly, and the pine surge effect can be improved. Moreover, since the coil spring itself bends according to the shape of the body, the adhesion is increased and the pine surge effect can be further improved. At the same time, the coil spring itself can act as a cushion, suppressing deterioration in cushioning properties and improving practicality.
