Description

Device and method for adjusting seat belt buckle of vehicle {Control device & method of seat belt buckle for vehicle}

The present invention relates to a seat belt buckle position adjustment device and method of an automobile, and more particularly, when a seated passenger detects a seat that is large enough to be uncomfortable to wear the seat belt, the seat belt tongue and buckle is automatically provided to the passenger easily. The seat belt of the car can reduce the damage caused by not wearing the seat belt because the angle and length of the rod equipped with the buckle are adjusted to move the buckle to the position where the buckle can be moved. It is to provide a buckle positioning device and method.

In general, a seat belt of a car is installed and used for each seat to protect passengers from the impact on the car in the event of an accident caused by a collision, collision or other obstacle with another car while driving. Types include two-point belts, three-point belts, diamond belts, and full harness belts.

The two-point belt is also referred to as a hip belt or a lap belt in support of two points on the left and right sides of the waist, where the lap refers to a seated position from the waist to the elbow joint and there is no shoulder belt. Although it is inferior to the three-point belt, the effect of the out-of-door discharge prevention effect in the riding dimension is large.

The three-point belt is the most widely used belt in passenger cars, and it is a type that supports two points by fixing two points on the left and right sides and one point on the shoulder. This is a lap belt that constrains the waist and a shoulder belt that constrains the upper body. It is.

The three-point belt has a separate three-point seat belt, in which the waist belt and the shoulder belt are separated and joined by an iron structure, and the webbing of the wrap belt and the shoulder belt is continuously connected in a row, and the tongue plate is free to the webbing. There are two types of continuous three-point seat belts that can slip.

In view of the stability of the wearer, a three-point or higher type is preferable, and it is the most standard seat belt system because of its high level of protection against collisions and its high practicality.

Diagonal belt is a two-point belt that restrains the upper body only. It is called a shoulder belt. It is a type used in Europe at the beginning of the seat belt. Since the lower body has no restraint function, it has been excluded from the standard in many countries such as Japan and the United States.

In addition, the full harness type belt has better restraint performance than the three-point type belt, but it is complicated to install and difficult to install in a car.

Seat belts classified into the above types are generally composed of a webbing, a retraction device, an ALR, an ELR, a buckle and a tongue plate, an anchorage, and the like.

In other words, webbing is made of synthetic fibers such as nylon and polyester in a band shape of about 50 mm in width and about 1.2 mm in thickness, and is woven according to the use of shoulder belts, waist belts, and continuous belts. And elongation are set.

These webbings are the parts that absorb the collision energy, and various standards are set in the laws and regulations of each country about their performance.

The retractor adjusts the length of the belt according to the seating position or physique, and is a device for storing the belt when not in use.The ALR (Automatic Locking Retractor) fits the lifter when the webbing is pulled out and installed. It is a device that can not be pulled out anymore because it is locked at the position wound up to the length of the body. It is mainly used for the waist belt because the movement of the body is limited and the body can be firmly fixed.

And ELR (Emergence Locking Retractor) is a shock detection device for locking in the event of a crash or sudden braking, it is to be able to pull out freely in the usual, the detection method is the mainstream type to detect the deceleration of the vehicle body by a pendulum, Some webbings are pulled rapidly, and many of them are hybrid.

There are several types of devices for improving the restraint performance in the event of a collision. That is, to prevent an increase in the amount of webbing released by the 'winding up' of the ELR in the event of a collision, webbing clamps are applied to lock the webbing at the ELR outlet, or a collision is detected to actively draw the webbing to the combustion pressure of the gunpowder. Pretensioner, and webbing clamps, etc., and a type of pulling the buckle by the force of the spring as a deformation of the pretensioner.

In addition, anchorage is conventionally a steel structure for fixing one end of the webbing to the body, but an adjustable anchor structure that improves comfort when worn by adjusting the position of the shoulder belt up and down in accordance with the dimensional build. And many other things, such as motorized, seat position interlocking, memory mounted electric, etc., are being introduced.

In addition, the buckle and tongue is a device for mounting or dissociating the seat belt, and the buckle for the front seat is mostly self-supporting so that it can be operated with one hand, and the seat for improving the fitability when the belt is worn. There are a lot of buckle which I unified in.

That is, in order to mount the seat belt, the seat belt tongue must be inserted into the hole of the seat belt buckle, and in the related art, as shown in FIG. 1, the buckle 70 is installed at the lower side of the seat 80 so that the passenger After seating, after rotating the body to the buckle position, bent to confirm the position and hole of the buckle (70).

Therefore, in the case of a passenger with a large physique such that the operation for coupling the seat belt tongue to the buckle is difficult, it is inconvenient to wear and there is a problem in that a serious injury occurs in a crash of the vehicle due to the case where it is not worn at all. Even in the case of passengers, the combination of the tongue and the buckle is not easy, so there is a case in which the seat belt is not worn, thereby causing a safety problem.

Accordingly, an object of the present invention is to provide an apparatus and method for adjusting the buckle position of an automobile seat belt in which a seat belt buckle can be automatically fastened so that a passenger can conveniently wear the seat belt by combining the buckle and the tongue. To provide.

The object of the present invention is to combine the length adjustment motor and the angle adjustment motor on the rod equipped with the buckle to move the buckle to a convenient position automatically when the weight sensor is installed on the weight sensor installed on the seat and each connected a timer to these motors This is achieved by configuring the angle and length of the rod to be adjusted by driving the motor for a set time.

In the present invention, when a large-sized passenger is seated so as to make it difficult to couple the seat belt tongue to the seat belt buckle to wear the seat belt, the passenger can easily easily combine the seat belt tongue and the buckle when the seat is detected. Since the angle and length of the buckle-loaded rod are adjusted to move the buckle to the position where the buckle can be moved, the seat belt can be conveniently worn by the passenger, thereby preventing safety accidents. will be.
