Detailed description of the invention

The present invention relates to a safety device for an automobile seat, and more specifically, a general seat so that the seat can be moved forward by inertia and the backrest can be flipped back when a collision or a collision accident occurs while driving a vehicle. The present invention relates to a safety device that can further protect the occupant by releasing the locking device of the angle adjusting device of the back and front movement devices 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. In particular, in the case of the driver's seat, the backrest of the front and rear movement control devices of the seat to maintain the proper posture for driving considering the individual physical condition of the driver An angle adjusting device is provided.

The adjustment devices can keep the chair suitable for driving, but the seat belt has been widely used for the purpose of preventing the occupant's body from escaping from the seat in the event of a collision or crash while driving the vehicle. The pocket was known

The seat belt or pouch protects the 60-mile bumper from the steering wheel during a collision or left and right collision while driving so that the body of the occupant is tied to the seat so that the occupant's body resists the inertia force that is to be displaced forward from the seat. It was not possible to fundamentally protect the body of the occupant from impact.

In particular, when the vehicle collides with an obstacle in front of the vehicle at high speed, the body may be fatally injured between the steering wheel and the backrest, which are pushed by the impact even if the safety belt is worn, and injuries caused by flying 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 before reaching its original purpose due to sharp fragments such as glass fragments or debris that enters through the windshield of the car. There is a problem that there is a risk of damage.

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. This safety device allows the seat to be moved backward 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 adjusting device to the bottom of the body, support the fixed rail and the guide rail with a spring, and move the guide rail with the solenoid valve supported on the support piece fixed to the bottom of the body. The backrest of the hood fixed to the bottom of the body at the rear of the fixed rail when the seat is retracted so that it can be locked and prevented the operation of the solenoid valve by the electronic sensing device and the contact sensing device installed in the front bumper of the vehicle. By letting the dragon hedge lever trip over, you can force the seat back and lean the back. To protect riders in the event of a vehicle crash

The safety device provided in Korean Patent Publication No. 91-10075 is designed to allow the seat belt to be flipped backwards due to tension of the seat belt in the event of a collision, and the structure of the seat belt tensioning device and the back folding device are very complicated. However, excessively strained seat belts hold the occupants on the back of the seat, causing severe damage to the abdomen, chest, and folds, and the strained seat belts make it almost impossible to escape or rescue an accident vehicle. There was a problem.

In addition, Japanese Patent Application Laid-Open No. 63-125456 (U.S. Patent No. 4,738,485) discloses a seat assembly with a passenger restraint device that allows the seat to be moved forward in the event of a collision and the seat is moved forward. When the wire rope is driven through the pulley installed in the seat with the momentum, the movement of the wire rope is used to wind and tension the shoulder belt into the inlet device to restrain the passenger to the seat safely. Separately, 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. Because the angle between the seat and the backrest is maintained as it was before the impact They couldn't be safely protected from rushing steering wheels, glass fragments, and shattered debris. In particular, in case of a collision, the body is bounced forward due to inertia and then hits hard against the backrest of the seat. Therefore, in order to prevent the body from being caught by the 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 clavicle by the shoulder belt, and the tensioned shoulder belt makes it almost impossible to escape or rescue the accident vehicle.

Korean Patent Publication No. 94-011846 of the present invention intensively examines such a conventional problem, and as a result of the inertia force received by the seat and the occupant by releasing the front and rear movement adjusting devices of the seat from the locked state in the event of a collision or a collision accident while driving the car. If the seat back can be moved forward, and the backrest angle adjustment device is also released from the locked state so that the backrest can be flipped back by the inertia force received by the occupant, the body of the occupant can be protected more securely. Upon learning, the present invention has been completed.

However, in the previous crash, the steering wheel could reach the driver's seat.

It is an object of the present invention before and after the seat back movement adjustment device and the like so that the seat back can be moved forward by the inertial force generated in the event of a crash even without wearing a safety belt that puts pressure on the occupant It is a role that releases the locking state of the backrest angle adjusting device as a role of releasing the force of squeezing power, and it is installed in the front and back movement adjusting device and the backrest angle adjusting device. It provides a safety device for the car seat that connects the shock sensing means with the coaxial cable and the means for releasing the seat, the front and rear movement adjusting device and the backrest adjusting device, and the impact generated when a collision and a collision or a collision accident occurs while driving Is detected by the front and rear bumpers or shock detection switches, and if the front and rear bumpers detect In addition to the switches installed on the front and rear bumpers, there are shock switches installed in the front and rear bumpers, and the front and rear movement adjustment devices of the locked seats and the locking devices that can flip the backrest at the same time are released. To provide the safety of the occupants.

However, the existing invention alone could not protect the steering handling device with a 5 mile bumper, so it could not be prevented from being pushed into the driver's seat and damaging the driver.

However, when the 60 mile bumper is researched and attached, the bumper itself is installed like the 5 mile bumper to give elasticity, and it is safe from the steering wheel because the steering wheel is safely operated to eliminate the impact of inertia. .

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

The inertia force received by the seat and the occupant can move the whole seat S forward and at the same time lean back the backrest S '. It can be a safe protection.

In particular, due to the inertia force received by the passenger from outside, front, back, left, and right, without pressing or restraining the body due to the pin that adjusts the seat state before and after the chair and the pin that adjusts and secures the angle of the backrest during the collision. (A) Protects the five-mile bumper from debris and glass fragments and impacts that can penetrate the windshield in the event of a crash, as the backrest (S ') makes the occupant's body lie down from the sitting position. However, the invention of the 60-mile bumper will result in a fatal wound due to the steering wheel being pushed out. However, if the current 5-mile bumper and the lamp are installed, the 60-mile bumper will be installed inside the 5-mile bumper, so the aesthetic will be present and shocked. Even more secure. Therefore, the electricians and passengers who drive all cars that install the invention will be safer.
