Description

Seat for protecting a passenger's a neck for vehicles}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a neck protective vehicle seat, and more particularly, to a neck protective vehicle seat capable of closely supporting a passenger's head during driving and preventing a neck injury of a passenger during a rear collision.

In general, the top of the seat back of the car seat is equipped with a headrest that can support the head of the occupant provides a function to comfortably support the head of the occupant while driving.

On the other hand, during the rear collision of the vehicle, the body of the occupant is pushed backward by the inertia, and the occupant's head is bent backwards while the neck is bent, and the neck is easily injured.

However, the conventional headrest can adjust only the height at a certain height in the vertical direction from the seat back according to the physique of the occupant or driver, the headrest can not be adjusted in the front and rear direction of the seat.

Therefore, the degree of neck injury varies depending on the sitting position of the occupant or the driver during the collision.

Specifically, if the distance between the occupant's head and the headrest is close, the headrest prevents the head restraining of the occupant's head in the event of a collision, thereby preventing the neck from being bent. If a collision occurs, the head of the occupant will be leaned back and the headrests will not support the head, which can cause severe neck injuries.

That is, in order to prevent the occupant's neck injury in the event of a collision, it is preferable that the occupant's head is positioned adjacent to the headrest, but the conventional seat headrest can be adjusted only in the vertical direction of the seat back, It is difficult to prevent the neck injury of the occupant in the rear collision accident because it is impossible to adjust.

The present invention is to solve the above-mentioned shortcomings, the advantage of the present invention is that the headrest is closely supported on the head of the driver or the occupant to provide a more comfortable ride, and can minimize the neck injury of the occupant during the rear collision accident To provide a vehicle seat for neck protection.

First Embodiment

Referring to the first embodiment of the present invention in detail with reference to the accompanying drawings as follows.

Neck protection vehicle seat of the present invention and a bracket (10) fixed to the roof panel (11); An elastic body 13 and a support rod 12 hinged to the bracket 10; A head support member 14 fixed to a lower end of the support rod 12 so as to be positioned at an upper end side of the seat back 20; An actuator (15) for intermittent operation of the support rod (12) by electrical control; Technical features of the present invention include a pressure sensor 16 for sensing the pressure acting on the seat back 20 and driving the actuator 15.

The bracket 10 is provided to be firmly fixed to the roof panel 11, and the support rod 12 is rotatably arranged in the bracket 10 by the hinge shaft 12a.

An elastic body 13 is elastically supported between the bracket 10 and the support rod 12, and the head support member 14 fixed to the lower end of the support rod 12 has a restoring force within a predetermined angle θ, It is possible to move in the direction.

The elastic body 13 may preferably set the elastic modulus of the elastic body within a range where a large force is applied to the neck of the occupant when the occupant supports the head to the head support member 14 to operate.

Actuator 15 is provided on the upper end of the support rod 12, the support rod 12 is determined whether or not the operation of the actuator (15).

Specifically, when the actuator 15 does not operate, the support rod 12 is supported by the bracket 10 and the elastic body 13 and is movable together with the occupant's head within a predetermined angle range.

When power is applied to the actuator 15, the actuator 15 extended to the support rod 12 is driven by the set stroke to rotate the support rod 12 to thereby rotate the head support member 14 to move to the head of the occupant. Let's do it.

The pressure sensor 16 is provided in the seat back 20 to sense a pressure that the occupant acts on the seat back 20.

The pressure sensor 16 is connected to the actuator 15, and the pressure sensor 16 outputs a control signal only at a specific pressure or higher to drive the actuator 15.

The pressure sensor may be installed at two or more positions on the seat back to more accurately sense the load acting on the occupant, and a well-known signal conversion circuit is provided between the pressure sensor and the actuator to convert signal levels. The signal transmitted from the pressure sensor may be converted into an actuator driving signal to be transmitted to the actuator.

Looking at the operation of the neck protection vehicle seat of the present invention configured as described above are as follows.

When a collision accident occurs in the rear of the vehicle, the occupant is pushed to the rear by the impact of the collision, the pressure sensor 16 provided in the seat back 20 detects the pressure acting from the upper body of the passenger The control signal is transmitted to 15.

As shown in FIG. 3, the actuator 15 receiving the control signal is driven by a set stroke to rotate the support rod 12 so that the head support member 14 moves to the head of the occupant.

Since the head support member 14 is positioned to move to the head of the occupant, the head supporting member 14 is quickly supported by the collision impact to prevent the neck of the occupant.

When the actuator 15 is not operated in a normal driving state, the head support member can be moved in the front-rear direction within a range of an angle, so that the occupant can support the head to the head support member and take a more comfortable posture.

Second Embodiment
