Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air bucket seat for vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airbag seat for an automobile, and more particularly, to an airbag seat for an automobile, The present invention relates to an air bucket seat for an automobile, and more particularly, to an air bucket seat for an automobile which enables a comfortable ride and a stable running by maintaining a posture of a driver in a posture suitable for driving the vehicle by actively sensing the seat by controlling the seat.

Generally, the safety of the car should be the highest priority. To this end, manufacturers of automobiles should invest a lot of development cost to control the car or the occupant in a more convenient, safe, and efficient manner. .

In addition, during the technology development of the automobile, the seat for the passenger must maintain the driver's body in a proper posture for driving the vehicle in order to smoothly run the vehicle without hindering the riding feeling of the driver while passing the road surface or uneven road, The driver and the passenger tend to lean to the left or the right depending on the turning state of the vehicle, thereby reducing the ride quality of the automobile and hindering smooth driving.

However, there is a need for an automobile seat that maintains a comfortable and stable ride for the passenger of the vehicle and maintains the body of the passenger sitting on the seat of the vehicle to a position suitable for the driving and comfortable ride of the vehicle while the vehicle is turning to the right or left , Research on this is actively being carried out.

The existing automobile seat is divided into a conventional car seat cover to convert it into a bucket seat and a method to reduce the occupant's leaning at the time of sudden start and sudden stop. The conventional automobile seat is covered with a cover and converted into a bucket seat The seat of the vehicle is inconvenient because both sides of the seat always surround the body of the driver or the occupant, so that it is inconvenient for the driver to get in and out of the automobile, and during the straight running without turning or turning, the comfortable posture of the driver or the occupant There is a difficulty.

BACKGROUND ART As a prior art of a bucket seat for an automobile, Korean Patent Laid-Open No. 10-2008-0018387 (Mar. 28, 2008) discloses a vehicle seat which is capable of reducing a nose- So as to prevent passengers from leaning forward and to reduce the uncomfortable feeling of the passengers striking forward in every emergency braking.

However, such an automobile bucket seat is useful only for reducing the tilting of the passenger's posture toward the front or rear by adjusting the inclination of the seat back and forth at the time of sudden start or sudden stop, thereby solving the uncomfortable feeling. It is difficult to expect.

In order to prevent the driver's body from being pushed forward when the vehicle suddenly stops, the inclination of the seat is adjusted rearward. When the inclination of the seat is adjusted rearwardly, the front portion of the seat on which the driver's hips and thigh are seated is raised The front portion of the seat is raised and the driver's foot is released from the brake under pressure in order to brake the vehicle. This causes the pressure applied to the brake to be released and the braking of the vehicle to be released, causing an accident Inefficient.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a control apparatus for an automobile which actively controls an automobile seat in order to maintain a posture of a driver inclined according to a turning state and a speed of the automobile, The seat can be inflated in accordance with the turning state and the speed of the driver, and the seat can be inflated in accordance with the driver's convenience. Further, the inflated seat can comfortably cover the driver ' The purpose of the bucket seat is to provide.
