Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a vehicle seat having a speaker on a headrest.

[Conventional technology]

BACKGROUND ART Conventionally, as an automobile seat, in order to comfortably listen to music and the like, a speaker is attached to a headrest bracket that is a core body of a headrest, and the headrest bracket is wrapped with a speaker in a pad and a skin. It is known that the headrest is built into the headrest.

[Problems to be solved by the device]

By the way, conventionally, in a car seat without a speaker,
When an impact more than a predetermined amount is applied to the headrest from the front due to a vehicle collision or the like, the headrest bracket is deformed by the impact force so that the impact can be absorbed.

However, when this is applied to the above-mentioned speaker type automobile seat, the following problems occur.

That is, in the case of the above-described speaker built-in type, the rigidity of the headrest is increased by incorporating the speaker in the headrest as compared with the case without the speaker. Therefore, if the same headrest bracket as that without the speaker is used, the headrest bracket will not be deformed even if an impact is applied to the headrest, and the impact force cannot be absorbed. Therefore, in the case of the speaker built-in type, there is a problem that the headrest bracket having a lower rigidity than that in the case without the speaker must be used, and the same headrest bracket as that without the speaker cannot be used. Therefore, for manufacturers,
This has been a cause of increased manufacturing costs and component management costs. Also, for users, if they want to install a speaker after purchasing a type without a speaker,
In addition to simply mounting the speaker, it is necessary to replace the entire headrest for the type where the headrest can be separated from the seatback, and for the type where the headrest is integrated with the seatback, the entire seatback,
There is a problem in that replacement is time-consuming and expensive.

In view of the above circumstances, the present invention makes it possible to use the same headrest bracket as an automobile seat without a speaker in an automobile seat with a speaker so that it can be manufactured at low cost and an automobile without a speaker. The present invention intends to provide an automobile seat that can be easily changed from the automobile seat.

[Means for Solving the Problems]

A vehicle seat according to the present invention includes a headrest bracket, which is a core body of the headrest, and a speaker, and the speaker is attached to the headrest bracket, and the speaker is attached to the headrest bracket of the speaker. The headrest is provided with a fragile portion that breaks when a predetermined force or more is applied from the front.

[Action]

According to the above configuration, when an impact more than a predetermined amount is applied to the headrest from the front, the fragile portion of the mounting portion of the speaker is broken, and the impact is alleviated.

〔Example〕

1 to 4 show an embodiment of an automobile seat according to the present invention. This vehicle seat includes a seat back 1 and a headrest 2. The seat back 1 has a back frame 13 composed of a pipe 11 and a spring 12 as a core body, and wraps this with a pad 14,
Further, it is configured such that it is covered with an epidermis 15.

The headrest 2 has a headrest bracket 3 as a core thereof, a pair of left and right speakers 4, a rear pad 5 and a front pad 6, and is integrally provided at an upper end portion of the seatback 1. The rear pad 5 is integrally formed with the pad 14 of the seat back 1, and a recess 51 for housing the speaker 4 is formed on the front surface thereof.

The front pad 6 is formed by integrally adhering a cushioning material 62 to the surface of a structural member 61 made of resin or the like, and covers the opening of the recess 51 of the rear pad 5 so as to cover the front of the rear pad 5 with a rear portion. The pad 5 is detachably fitted by its elasticity and its elasticity. The front pad 6 is formed with a plurality of through holes 63 having a small diameter in order to improve the sound quality of the speaker 4.

The headrest bracket 3 is fixed to the upper end portion of the back frame 13 and is integrated with the rear pad 5 so as to be arranged at the bottom of the recess 51 of the rear pad 5. Holes 31 for inserting the speaker 4 are formed on the left and right sides of the headrest bracket 3, and these holes 31 are also provided.
A screw hole 32 for mounting the speaker 4 is formed around the.

The speaker 4 includes a main body 41 and a mounting portion 42 integrally formed around the main body 41. A mounting hole 43 is formed at the tip of the mounting portion 42. Further, a notch 45 is formed in a root portion (weakened portion) 44 of the mounting portion 42, so that when the headrest 2 is applied with a predetermined force or more from the front side, the root portion 44 is sheared. 44 is fragile and weakened. The speaker 4 has a hole 3 for inserting the speaker 4 in the rear part of the main body 41.
It is housed in the recess 51 of the rear pad 5 so as to be fitted into the head pad 1 and is detachably mounted on the headrest bracket 3 by screwing the screw 7 into the mounting hole 43 and the screw hole 32 for mounting the speaker 4. There is.
A stereo (not shown) is connected to the speaker 4 via an electric cord (not shown), and a stereo electric signal is input from the stereo.

The rear pad 5 and the front pad 6 fitted to the rear pad 5 are covered with a skin 21 integrally formed with the skin 15 of the seatback 1. A fastener 22 is provided on the outer skin 21 along the boundary between the rear pad 5 and the front pad 6, and by removing the fastener 22, a portion 23 of the outer skin 21 covering the front pad 6 can be turned. It is like this. Therefore, part 2 above
After turning 3 to expose the front pad 6, the front pad 6
The speaker 4 in the headrest 2 can be replaced by removing the speaker from the rear pad 5.

When an impact force of a predetermined amount or more is applied from the front to the rear as shown by an arrow F in FIG. 2 to the headrest 2 of the vehicle seat having the above configuration, the impact force is transmitted through the front pad 6. Hanging on the speaker 4. When the impact force is applied to the speaker 4, the root portion 44 of the mounting portion 42 is fragile and weak, so that the root portion 44 is broken by shearing at one or three places, and the impact force applied to the speaker 4 is exerted. Will be released to the rear, and the impact force will be alleviated. According to the configuration of the headrest 2, even if the root portion 44 is destroyed and the speaker 4 comes off the headrest bracket 3 as described above, the speaker 4 is wrapped with the rear pad 5 and the front pad 6. Therefore, there is no fear that the speaker 4 will drop out or pop out.

The present invention may be applied to a device in which the headrest can be separated from the seat back.

[Effect of device]

Since the vehicle seat according to the present invention is provided with the weak portion having a small bending strength in the mounting portion of the speaker to the headrest bracket, even if a large impact is applied to the headrest from the front, the weak portion is destroyed and It is designed to be able to absorb shocks. For this reason, even if the same headrest bracket as that used without the speaker is used, it is possible to absorb the impact when the impact is applied to the headrest from the front. Therefore, the headrest bracket can be shared with the case without a speaker, can be manufactured at low cost, and it is possible to change from the type without a speaker by simply attaching the speaker without changing other parts. Become.
