Car Seat Protector {Car-Chair Protect}

.

The present invention relates to a safety device for an automobile seat, and more specifically, to allow the seat to be moved forward by inertia in the event of a collision or a collision while driving a vehicle, and the front of the conventional seat so that the backrest can be flipped backward. The present invention relates to a safety device that can more securely protect the occupant by releasing the locking device of the angle shift device of the back transfer device and the backrest to make the occupant sit on the seat from the sitting position.

In general, the car seat is made in consideration of the average physical condition of the user. Especially in the case of the driver's seat, the backrest of the front and rear movement control devices of the seat to maintain a proper posture for the driver considering the individual physical condition of the driver An angle adjusting device is provided.

Although the adjustment devices can maintain a proper posture for driving, the body of the passenger is separated from the seat because it cannot prevent the occupant's body from being bounced forward by inertia during a collision or collision during driving of the vehicle. Seat belts have been widely used for the purpose of preventing them, and in recent years there has been known an air pocket that expands momentarily.

The seat belt or pouch is basically intended to bind the passenger's body to the seat so as to resist the inertia force that the passenger's body is trying to break forward from the seat in the event of a collision or collision while driving, and fundamentally protects the passenger's body from impact. I could not.

In particular, when the vehicle collides with an obstacle in front of the vehicle at high speed, even though the seat belt is worn, the body may be fatally injured between the steering wheel and the backrest, which are pushed by the impact, and injured by scattered fragments such as glass fragments. There was no way to escape. Air bags not only make it difficult to escape out of the car in the event of a fire or collision, but also achieve their original purpose by sharp fragments like glass fragments or debris that enters through the windshield of the car. There was a problem that there is a risk of damage before.

Safety devices for solving such problems include Korean Patent Publication No. 89-3619, Patent Publication No. 91-10075, and Japanese Patent Laid-Open No. 63-125456.

Korean Patent Publication No. 89-3619 discloses a passenger safety device in the event of a vehicle crash. The safety device allows the seat to be moved backwards in the event of a collision and the back of the seat can be flipped back. Secure the separate rail that is inserted to move the guide rail of the positioning device to the floor of the body, support the fixed rail and the guide rail with a spring, and guide the rail with a solenoid valve supported on the support piece fixed to the floor of the body. Locked to prevent movement, and the electronic sensing device and the contact sensing device installed on the front bumper of the car control the operation of the solenoid valve, so that the rear part fixed to the floor of the body at the rear of the fixed rail when the seat is retracted The release lever for locking the back was forced to retract the seat and lean the back. Because could not protect an occupant during a vehicle collision.

Because the fact that the body is bounced forward by a very large inertia force in the event of a collision, it is well known that in order to retract the seat when a very large inertia force due to the braking state and the weight of the occupant is applied rather than the driving speed during the collision. Not only should the seat be pulled back with a force greater than the very large inertial force, but the seat must not be thrown forward and the driver must be held very firmly to the seat to move backward with the seat. Due to the very high tension applied, the abdomen, chest and collarbone of the occupant are seriously damaged, and it is almost impossible to escape or rescue the accident vehicle due to the tensioned safety belt. As the number of operating means added to the gears had to be greatly modified, the tension coil springs consisted of reversing the existing guide rails that secured the seats from a separate rail fixed to the floor of the vehicle in the event of a collision. Since the tension coil spring is in an excessively relaxed state in general, the elasticity is reduced, so there is a problem that the reliability of reversing the seat with a very large force at a critical moment such as in a crash accident is very low. .

The safety device described in Korean Patent Publication No. 91-10075 is designed to allow the back of the back to be flipped while the seat belt is tense in the event of a collision. The structure of the seat belt tensioning device and the back of the back device are very complicated. However, the excessively strained seat belts that hold the occupants on the back of the seats can cause severe damage to the abdomen, chest and collarbones, and the strained seat belts make it almost impossible to escape or rescue the accident vehicle. There was a problem.

In addition, Japanese Patent Application Laid-Open No. 63-125456 (US Pat. No. 4,738,485) discloses a seat assembly with a passenger restraint device that allows the seat to move forward in the event of a collision and the seat moves forward. The wire rope is driven through the pulley installed on the seat with the momentum, and the amount of movement of the wire rope is used to secure the passenger to the seat by winding and tensioning the shoulder belt into the inlet device. Apart from the device, the device supporting the seat to move forward and the device for winding and tensioning the shoulder belt must be installed in an interlocked manner. Since it is only slightly inclined, the angle between the seat and the backrest is maintained as it was before the collision. City could not be protected from flying debris, such as pieces of glass and pushed the incoming steering wheel. In particular, in case of a collision, the body is bounced forward by the inertia and then hits hard toward the seat's backrest, so in order to hold it on the seat with a shoulder belt, a very large tension must be applied momentarily to the shoulder belt. There is a high risk of fatal damage to the abdomen, chest and collarbone area by losing shoulder belts, and the tensioned shoulder belts make it almost impossible to escape or rescue the accident vehicle.

The present inventors have made a thorough examination of such conventional problems, and in the event of a collision or crash while driving the vehicle, the seat is moved forward by the inertial force received by the seat and the occupant by releasing the front and rear movement adjusting device from the locked state. In order to complete the present invention, it will be understood that the backrest can be more safely protected if the backrest is flipped back by the inertial force received by the occupant. Reached.

An object of the present invention is to move the seat forward and also the seat back before and after the seat back by the inertial force generated in a crash accident even without wearing a safety belt that puts pressure on the occupant and the like before and after the seat adjustment device Before and after the seat, the means for releasing the locking state of the support angle adjustment device is installed in the back movement adjustment device and the back support angle adjustment device. The present invention provides a safety device for an automobile seat in which a means for releasing the rear movement adjusting device and the backrest angle adjusting device is connected.

An object of the present invention is to detect the impact generated in the event of a collision or collision during driving of the vehicle from the front and rear bumpers, and the angle adjustment device of the front and rear movement adjusting device and the backrest of the seat locked at the same time as the impact detection It is to provide a safety device of the car seat that can release the seat to move the seat forward by the inertia force, and to tilt the backrest back.

Hereinafter, the present invention will be described in more detail by way of example.

The present invention is the electronic control unit 1 of the seat adjustment device for releasing the front and rear movement adjustment device (A) of the seat and the angle adjustment device (B) of the backrest simultaneously from the locked state as illustrated in FIG. Front shock detection unit (2) and rear shock detection unit (3) for detecting an impact that is transmitted from the front and rear bumpers during a driving or collision accident while driving the vehicle to send an operation signal to the electronic control unit (1) of the seat adjustment device Consists of

In the safety device of the present invention configured as described above, as illustrated in FIG. 2, collision with an obstacle, such as another vehicle C2, or an obstacle and a collision accident, such as another vehicle C3, may occur during driving of the vehicle C1. When an impact is applied to the front or rear bumpers FB and RB, the electronic control unit 1 of the seat adjusting device receives an operation signal by the front and rear shock detection units 2 and 3 that are embedded or attached to these bumpers. The seat is released by the inertia force corresponding to the acceleration of the driving vehicle because the front seat and the back movement adjusting device (A) and the backrest angle adjusting device (B) are normally released. As represented by the dashed line, the forward and at the same time the backrest (S ') is bent backwards so that the occupant's body is changed from sitting to lying down.

Such a safety device of the present invention moves the whole seat (S) forward by the moment of inertia received by the seat and the passenger when an impact is applied to the front and rear bumpers (FB) and (RB) when a collision or a collision accident occurs while driving the vehicle. At the same time, the backrest (S ') can be flipped back to protect the occupant from impact.

In particular, it does not press or restrain the occupant's body in the event of a crash, but it makes the occupant's body lie down from the sitting position while lying down by the inertia force that the occupant receives. Because it is far from the debris of the obstacles and steering wheel pushed away by glass fragments and impacts, there is a feature that can safely protect the occupants.
