Description

An Air Bag Device For Protecting A Head And A Neck

The present invention relates to an airbag, and more particularly, to a head and neck protection airbag device for mounting on the head restraint of the vehicle interior seat to absorb the shock to the head and neck bones when the car crashes.

In general, the seat of the car can be classified into a hip support, a waist support, and a head restraint according to the body part in close contact. Here, the head restraint is connected to the upper part of the waist support by a solid shaft that can be adjusted in length.

The seat of such a vehicle has a function of allowing a passenger to sit and move, and a shock absorbing member such as a sponge or a spring is built in to protect the passenger from an external small impact.

The shock absorbing member is provided to absorb a small shock or vibration transmitted according to the road surface condition while driving to protect the occupant and to feel a more comfortable ride.

In the seat of a conventional car, the head restraint is provided to support the head of the occupant, but is arranged to be spaced apart from the head unless the head is intentionally flipped back so that the head can be easily rotated to secure the view of the surrounding environment. It is.

However, if a sudden start of the car occurs, the driver knows the moving room in advance and prepares. However, the occupant sitting in the driver's seat or the rear seat is unaware of this and suddenly the car's movements, especially the head, tilts backwards.

In this case, the most physically abnormal part can be called the neck bone area. The neck area is thinner and shorter than other parts of the body, and also supports a relatively large weight of the head, so when the head is flipped for this unprotected sudden movement, the neck bone or neck ligament part is subjected to a large load.

Such a sudden situation can be experienced by the driver. If a collision occurs in the rear of the vehicle, the driver may not prepare in advance, and the head is severely flipped back, which is likely to cause an abnormality in the neck.

In order to protect the head and neck area, a shock absorbing member is included in the head restraint of the seat. However, as mentioned earlier, when sitting in a seat with the posture upright, there is a problem in that the head restraints are spaced at a certain distance from the back of the head to provide room for the head to be flipped in a sudden situation.

The seat can be arranged vertically by adjusting the position of the seat, but in this case, it is inconvenient to sit for a long time, so the seat position is usually used to lay back slightly.

In addition, the shock absorbing member in the head restraint is usually contained at a high density in the head restraint, and thus has a relatively large rigidity compared to a human head. Therefore, when the head is suddenly flipped back and hit the head restraint, rather than absorbing the shock, rather than transmitting the shock to the head or neck, it does not function properly as a protective equipment.

Therefore, the present invention is conceived in view of the above-mentioned conventional problems, the first object of the present invention, the structure of the head and neck structure that can be always attached to the head restraint of the car seat to protect the head and neck from sudden external impact A head and neck protective airbag device.

The second purpose of the present invention is to provide a head and neck protective airbag device having a fixing means that can be easily attached to the head restraint with a fastening means such as a clip belt, a fastening belt, a press button, a bulk tape, and the like. It is about.
