The present invention may have various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a configuration of an automotive seat impact reducing apparatus according to an embodiment of the present invention. The vehicle seat impact reducing apparatus 100 according to an embodiment of the present invention includes a rear impact detecting unit 110, a shoulder adjusting motor 120, a booster 130, a hall sensor 140, a shoulder adjusting frame 150, A headrest 160, a power supply unit 170, and a control unit 180.

The rear collision sensing unit 110 senses the collision acceleration G at the time of occurrence of a rear collision with respect to the vehicle, and is preferably installed near the rear bumper of the vehicle. The rear collision sensing unit 110 transmits the sensing value to the controller 180 so that the controller 180 can control other components according to the sensing value.

The shoulder adjustment device motor 120 operates in response to the signal when an operation command is input by the control unit 180, and accordingly the shoulder adjustment frame 150 moves.

The booster 130 boosts the voltage for instantaneous and quick operation of the shoulder adjuster motor 120 and transmits it to the shoulder adjuster motor 120 when an operation command is inputted by the controller 180. [

The hall sensor 140 detects the position before the collision of the shoulder adjuster 150 and transmits the sensed value to the controller 180.

The shoulder adjustment frame 150 supports the upper body including the shoulder of the occupant by a frame which is moved by the shoulder adjustment device motor 120. [

The headrest 160 is mounted on the top of the seat of the vehicle and is actuated by the active headrest actuating device to continuously support the occupant's head and neck when an impact is applied to the rear of the vehicle.

The power supply unit 170 supplies power necessary for the operation of other components, and the battery of the vehicle can operate as a power supply unit.

The control unit 180 controls the overall operation of the seat impact reducing apparatus 100 and controls the operation of the shoulder adjusting frame 150 and the headrest 160 in response to the rear impact of the vehicle.

Fig. 2 is a diagram showing the operation of the impact reduction device according to the operation amount according to the embodiment of the invention. Fig. 2A shows a case where the angle when the shoulder adjusting frame 150 is located at the reference position is set to 0 DEG. In the case where a strong impact such as at the time of a rear impact of the vehicle is sensed, the control unit 180 controls the shoulder control frame 150 and the shoulder control frame 150 according to the control command of the control unit 180, The headrest 160 moves forward. The moving range may be a predetermined constant value and may correspond to the intensity of the impact amount. Specifically, since the inertia of the passenger increases as the rear collision of the vehicle becomes stronger, the amount of displacement in which the shoulder adjustment frame 150 and the headrest 160 move in the direction toward the passenger may increase.

2B shows a state in which the shoulder adjusting frame 150 is positioned at an angle of 5 degrees with respect to the reference position, and when a strong impact such as a rear impact of the vehicle is detected, The rest 160 moves forward. The moving range may be a predetermined constant value and may correspond to the intensity of the impact amount.

FIGS. 2A and 2B show that when the shoulder adjusting frame 150 is positioned within a predetermined angular range from the reference position, when the same strong impact is applied as in the rear-end collision of the vehicle.

2C and 2D, both the shoulder adjusting frame 150 and the shoulder adjusting frame 150 are moved in the direction of the occupant when a strong impact such as at the time of the rear collision of the vehicle is applied when the shoulder adjusting frame 150 is positioned inclined toward the occupant in a predetermined angular range or more from the reference position . That is, when the shoulder adjusting frame 150 is positioned in a state inclined toward the occupant in a predetermined angle range or more from the reference position before the collision, when the strong impact is applied as in the rear collision of the vehicle, When the shoulder adjusting frame 150 is positioned in a state inclined by a predetermined angle or more relative to the reference position before the impact, the shoulder adjusting frame 150 may be excessively moved and impact the passenger, It is preferable not to move even when the same strong impact is applied.

The angle at which the operation is performed can be set differently according to the user's body shape, age, height, weight, etc., and can be changed as needed. The time at which the shoulder adjuster operates is 55 ms to 60 ms after the crash.

3 is a flow chart illustrating a method for reducing seat impact in an automobile according to an embodiment of the present invention. First, in a state in which the shock reduction system operates, the rear collision sensing unit 11 senses a rear collision of the vehicle (S100).

Next, when a collision is detected, it is determined whether the collision acceleration is equal to or greater than a reference value (S200). Even if a collision is detected, if the collision acceleration is less than a predetermined reference value, the impact reduction system can be set not to operate.

Next, when the rear collision of the vehicle is detected, the position of the shoulder adjusting device is controlled corresponding to the position before the shoulder adjusting device collides. Specifically, when the impact acceleration is equal to or greater than the reference value, it is determined whether the degree of inclination of the shoulder adjustment device before collision with respect to the reference position is equal to or greater than the first reference value (S300). If the impact acceleration is equal to or greater than the first reference value, If it is less than the first reference value, the shoulder adjusting device is controlled to move to a predetermined position (S400).

Next, when the position of the shoulder adjusting device is changed by the impact in the step S400, the step of returning the shoulder adjusting device to the position before the collision may be executed after a predetermined time elapses (S500).
