DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headrest.

[0002]

2. Description of the Related Art Conventionally, in order to provide a comfortable drive for a vehicle occupant, a headrest for supporting a head of a seated occupant on the seat is provided above a seat back. Is provided.

[0003] Investigations have shown, however, that the headrest, which should always be in contact with the head, is not in contact with the head in most cases.
This is because it is difficult to check the rear when the headrest is in contact with the head, and after all, when the driver can maintain a certain high speed for a predetermined time, such as when driving on a highway, the headrest is moved It is presumed that the driver may not drive the vehicle with the head in contact with the headrest when driving in an urban area where the driver frequently stops.

[0004] It has been confirmed that if there is a gap between the headrest and the head even if it is only a few centimeters, whiplash may occur if the vehicle is rear-end impacted at the time of stopping or running at low speed. That is, as a result of the investigation, it has been confirmed that, if the headrest is in contact with the head, if a rear-end collision occurs, whiplash does not occur, or even if it is slight, it is mild.

The present invention provides a headrest that prevents whiplash.

[0006]

The gist of the present invention will be described with reference to the accompanying drawings.

A headrest 1, which is attached to a backrest of a seat 2 provided on a vehicle and supports a head 3 of a seated person on the seat 2, is forcibly applied to the head 3 only when the vehicle is stopped or running at a low speed. The present invention relates to a headrest characterized in that the headrest is configured to be moved forward so as to contact with the headrest.

[0008]

When the vehicle is stopped and running at a low speed, the headrest 1 is moved forward and the headrest 1 is forcibly brought into contact with the head 3 of the seated person.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS The drawings illustrate one embodiment of the present invention.
This will be described below.

The headrest 1 of this embodiment is tilted forward to a predetermined angle by a suitable means at a running speed of the vehicle, in this case, 10 km / h, so that the vertical front surface of the headrest 1 is inclined. It is configured.

For example, when the vehicle speed is detected to be 10 km / h or less by an appropriate sensor, the headrest 1 is moved forward forward electrically or mechanically, and when the vehicle speed is 10 km / h or more, the headrest 1 returns. For example, the headrest 1 is configured to interlock with the engine rotation or interlock with the brake mechanism so as to fall forward.

The headrest 1 can be tilted forward in any configuration, such as a configuration in which the head contact portion 1a of the headrest 1 is tilted forward, a configuration in which the support rod 1b is tilted forward, and a configuration in which both are tilted forward. A configuration may be adopted.

The headrest 1 of the present embodiment takes into account that whiplash due to a rear-end collision is most severe at the time of stopping and running at low speed, and that rear-end collision at a speed of 10 km / h or more is rare. The vehicle speed is 10km /
h or less than 10 h / h
The speed is not limited to m / h, and the vehicle may be moved forward at a speed of 20 km / h or less.

In this embodiment, it is desirable that the speed setting can be arbitrarily adjusted.

In this embodiment, the headrest 1 is moved from the stop to the speed of 10 km / h.
Is in the forward position and is in contact with the driver's head 3. Then, when the speed of the vehicle reaches 10 km / h or more, the headrest 1 returns. Conversely, a vehicle running at a speed of 10 km / h or more applies the brakes and decelerates to a speed of 1 km / h.
When the speed reaches 0 km / h or less, the headrest 1 in the upright state comes into contact with the head 3 of the driver moving forward.

Therefore, according to the present embodiment, the headrest 1 always comes into contact with the driver's head 3 in a dangerous speed range in which severe whiplash is likely to occur when the vehicle is stopped or running at a low speed. Therefore, even in the event of a rear-end collision, the seat 2 becomes safe without whiplash.

By providing the headrest 1 of this embodiment also in the passenger seat, the rear seat, and the like, a more secure vehicle can be provided.

[0018]

According to the present invention, the headrest is securely in contact with the head of the occupant when the vehicle is stopped or running at a low speed, so that whiplash may occur even if a collision occurs. It is an extremely safe headrest without any.
