Abstract

PURPOSE: A safety belt locking device operating method adds electric locking device to the usual mechanical safety locking device so that the safety belt is rapidly and safely locked. CONSTITUTION: A locking device comprises a steering wheel(10), a pushing plate(20), a spring(30), a power switch(40), a steering wheel shaft(50), a safety belt(60), a solenoid locking device(70), a usual locking device(80) and a battery. When a car collides or suddenly stops, the upper body of a driver is pushed toward the steering wheel(10). The driver instinctively pushes the steering wheel so that the pushing plate(20) attached to the steering wheel(10) is pushed to push the switch(40) connecting the battery(90) with the solenoid locking device(70) so that the safety belt(60) is rapidly locked. When the car is suddenly turned, protrusive surfaces(A) formed on both of the pushing plate(20) push the switch(40) to lock the safety belt(60).

Description

How to operate seat belt lock by car steering wheel {omitted}

The present invention relates to a method of operating a vehicle seat belt lock for protecting a driver's safety during a road accident, a sudden braking and a sharp curve, and driving a vehicle. Is about a car seatbelt lock that can be locked more quickly and safely.

Conventional seatbelt locking devices are simply kinematic devices to prevent the driver from tumbling out of the car or hitting the steering wheel and windshield during a crash, fall, or sudden braking, resulting in poor safety, quickness, and significant impact on the driver. The seat belt is locked after the action has been transmitted. Immediately before a significant impact is transmitted to the driver's body and when driving at a sharp curve, the seat belt function is lost. Have a problem

The present invention is to solve this problem, the technical problem is to combine the electric locking device to the conventional kinematic seat belt lock device so that the seat belt can be locked quickly and safely.

Explanation of symbols on the main parts of the drawings

10: steering wheel

20: pressure plate

It is a spring 30

40: switch

50: handle shaft

60: seat belt

70: Solenoid lock

80: Conventional lock

90: battery

In order to achieve the above object, a power switch for connecting a battery power source to a solenoid lock device is installed between a handle and a handle shaft, and a solenoid lock device is attached to a conventional seat belt lock device. As a device, when described in more detail based on the accompanying drawings as follows:

1 shows a block diagram of the present invention.

2 shows an electrical circuit diagram of the present invention.

As shown in FIG. 1, the present invention includes a handle 10, a pressing plate 20, a spring 30, a power switch 40, a handle shaft 50, a seat belt 60, a solenoid lock 70, and a conventional lock 80. ) Consists of a battery (90) as a basic feature of the technical configuration

The driver's upper body is pushed toward the steering wheel, which is the direction of the vehicle, due to a collision accident and shock during braking.

At this time, the driver applies force to the hand and the arm holding the handle 10 to prevent the upper body from hitting the handle 10, whether instinctive or self-induced. Press plate 20 attached to the panel is pushed down by 0.5 cm and presses the switch 40 contact point for connecting the battery 90 power to the solenoid lock device 70, thereby connecting the power supply to the solenoid lock device 70. The seat belt 60 is quickly locked.

When the seat belt 60 is loosened, the driver removes the force applied to the handle 10. The handle 10 is operated to the original position by the suspension device, and the contact point of the switch 40 is dropped so that the power supply of the battery 90 is cut off. (60) is released

When the steering wheel 10 is rotated more than 20 degrees left and right when driving a sharp curve, the 0.5 cm projecting surface (A) made on the left and right sides of the pressing plate 20 connects the battery 90 power to the solenoid lock 70. The seat belt is quickly locked by connecting the power to the solenoid lock device 70 by pressing the switch 40 contact point.

When the seat belt 60 is released, the safety belt 60 is released from the sharp curve, and the handle 10 is returned to its original position.The protruding surface A of the pressing plate 20 is separated from the contact point of the switch 40 for connecting the battery 90 to the power source. It is blocked and the seat belt 60 is released.

As described above, when the present invention is used in combination with a conventional vehicle seat belt locking device, the solenoid lock device operates quickly and safely before a large impact effect is transmitted to the driver's body during crash accidents, sudden braking, and sudden curve driving. It is considered to be an innovative way to prevent accidents and protect driver's safety by giving stable driver's posture in case of accident.

Claims (2)

In constructing the operation method of the seat belt lock by the car handle, install a switch connecting the car battery power to the solenoid lock device between the handle and the shaft of the handle and install the switch to connect the solenoid lock device to the conventional lock device. The handle is suspended by the force applied to the arm, which is the stage immediately before a big shock is transmitted to the driver's body during a crash or sudden braking, and the pressing plate presses the switch contact that connects the battery power to the solenoid lock. Is quickly locked, and the protruding surfaces made on the left and right sides of the pressing plate press the switch contacts when driving at a sharp curve, and the seat belt is quickly locked, and there is no problem in the function of the conventional locking device when the switch is broken or an electric circuit is broken. Seat belt lock operation by car steering wheel, characterized in that The same way, The seat belt lock device of claim 1, wherein the seat belt lock device is manufactured using a solenoid.
