Description

Automotive Headrest Device with Neck Support

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head restraint for a vehicle, and in particular, a neck support for reducing the risk of injury by relieving the impact of a neck that is flipped when the head is flipped back while the body is rebounded by the rear collision of the vehicle. It relates to a head restraint device for a vehicle having a function.

In general, the head rest is installed on the top of the seat back so as not to be injured in the neck if the passenger's body is flipped back in the event of a vehicle crash.The head rest is inserted into the upper part of the seat back like a pillow and the seat back and There is an integral type that is integrated, and the integrated type is sometimes referred to as a high back sheet in the sense of having a high back.

1 is a perspective view showing a conventional seat and head rest, and FIG. 2 is a side view showing a conventional seat and head rest.

1 and 2, the headrest 10 of the related art is installed in the upper end of the backrest 3 of the seat 1 so that height adjustment is possible. Therefore, the height can be adjusted to suit the occupant's sitting height.

On the other hand, the head rest 10 installed as described above is leaning against the backrest of the occupant while the occupant is sitting on the seat 1, and the head is leaning against the head rest 10. The driver of the occupant is to be driven at a distance from the head rest 10 due to the driver to drive.

At this time, in the event of an accident due to a collision in the rear of the vehicle being driven, the occupant is inclined to load backward by inertia. At this time, since the body is supported by the backrest 3, there is no movement back, but the head portion leaned on the headrest 10 is moved back and forth by the force due to the collision and collides with the headrest 10. In particular, there is a risk of serious injury to the neck because the neck is flipped back momentarily.

The flipped head is blocked by the head rest 10, which prevents the neck from being completely bent backwards, thereby reducing the risk of an accident, but the head rests on the head while the head rests against the head rest 10 while the head is tilted back. . In addition, the head may be bent forward by the impact. In particular, the driver whose head is spaced apart from the head rest 10 is further aggravated.

As described above, the head rest as in the related art does not effectively support the neck part when the head of the occupant is leaned back due to an accident due to the weight, so that the occupant is injured.

In addition, the conventional head rest is formed to be flat, so that only the rear part of the head when the head is leaned away from the neck area at all times. Therefore, when boarding for a long time, the neck comes to be tired easily occurs.

The present invention has been made in order to solve the above-described problems, the head restraint of the occupant due to an accident caused by the collision by installing the auxiliary head rest rotatably provided with a neck support that can support the neck portion to the head rest It provides a head restraint device for a car that has a neck support function that can support a neck area when it is lost so that the impact can be alleviated to reduce the injuries of the human life as well as a comfortable operation by supporting the neck. Has its purpose.

The present invention is configured as follows to achieve the above object. In other words, in the head restraint for an automobile provided on the upper back of the car seat to support the head, the auxiliary head rest is rotatably supported and supported on both sides of the inner space of the space portion, which penetrates the head rest back and forth and is opened upward. On one side of the auxiliary head rest, a convex support for the occupant to support the neck area when the passenger leans over the head, means for rotating the auxiliary head rest back and forth, and means for shifting the position up and down when rotating the auxiliary head rest. There is a feature consisting of.

Hereinafter, with reference to the accompanying drawings will be described in detail for the head restraint device for a vehicle having a neck support function according to a preferred embodiment of the present invention.

3 is a perspective view showing a head restraint for a vehicle having a neck support function according to the present invention, Figure 4 is a side view showing a head restraint for a vehicle having a neck support function according to the present invention.

3 and 4, the present invention is installed in the upper backrest of the automobile seat (not shown), so that the head restraint 200 for the head to support the headrest 200, and penetrates back and forth When the occupant leans on his / her head on one side of the space 210 opened upward, the auxiliary head rest 220 supported on both sides of the inner side of the space 210 and rotatably installed It comprises a convex support portion 230, the means for rotating the auxiliary head rest 220 back and forth to support the site, and means for converting the position up and down when rotating the auxiliary head rest 220.

Meanwhile, in the above-described configuration, the auxiliary head rest rotating means includes rotating grooves 212 formed on both sides of the inner space 210 of the head rest 200, and coupling shafts 222 provided on both sides of the auxiliary head rest 220. The auxiliary head rest 220 is rotated only when the coupling shaft 222 of the auxiliary head rest 220 is on the rotary groove 212. At this time, the coupling shaft 222 can be rotated only if less than the diameter of the rotary groove 212, the above-described coupling shaft 222 is made of a cross section.

The above-described auxiliary head rest position converting means is provided with a guide groove 214 extending below the rotating groove 212 of the rotating means. The coupling shaft 222 of the auxiliary head rest 220 having a rectangular cross section is coupled through the rotation groove 212, is guided to the guide groove 214 and moved downward, and the installation is completed. Since the diameter of the 214 is related to the thickness of the coupling shaft 222, the auxiliary head rest 220 guided to the guide groove 214 is prevented from rotating. Therefore, in order to rotate the auxiliary head rest 220, the auxiliary head rest 220 is raised to the upper guide groove 214, the coupling shaft 222 can be rotated only when it is located in the rotary groove 212.

According to the present invention configured as described above, the back of the occupant is leaned on the backrest while the occupant is sitting on the seat, and the head is leaned on the head rest 200. At this time, in case of an accident due to a collision in a driving or stationary vehicle, the occupant is pushed backward by the inertia, and the body is restrained by the backrest so that there is no further movement backward. It is flipped back by the force due to the collision to hit the auxiliary head rest 220. At this time, because the support portion 230 supports the neck area, the impact is not only reduced, but the shock is absorbed to reduce the risk of injury.

Figure 5 is a side view showing the rotation of the headrest for a vehicle having a neck support function according to the present invention.

As shown in FIG. 5, the head rest 200 device of the present invention uses the side without the supporting portion 230 of the auxiliary head rest 220 or the auxiliary head when the side with the supporting portion 230 is to be used. Raise the coupling shaft 222 of the rest 220 up to the rotary groove 212 to rotate the surface to be used, and then place the auxiliary head rest 220 on the lower side of the guide groove 214 so that the passenger's preference The surface can be selected and used accordingly.

In addition, the rider can comfortably run because the neck is supported by the support unit 230 by leaning the head to the auxiliary head rest 220.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the technical idea of the present invention.

As described above, according to the present invention, when the head is tilted back due to the inertia of the collision accident and hits the head rest, the neck part is supported by the support part, thereby reducing the impact on the head and neck part, thereby reducing the risk. It can be effective.

Another effect of the present invention is that by using the surface with the support portion can be lean on the head and neck portion in the support when riding in a car in general, there is an effect that can reduce fatigue even for a long time driving.
