Description

승객용 안전벨트 경고시스템 및 그 경고방법{Passenger Seat Belt Warning System and Warning Method for the Same}Passenger Seat Belt Warning System and Warning Method for the Same}

본 발명은 승객용 안전벨트 경고시스템 및 그 경고방법에 관한 것으로서, 특히 운전석 외의 좌석에 승객이 탑승한 경우 상기 승객의 안전벨트 착용여부가 자동적으로 감지하고 착용이 이루어지지 않은 경우 이를 경고함으로서 승객의 안전을 도모할 수 있는 승객용 안전벨트 경고시스템 및 그 경고방법에 관한 것이다.The present invention relates to a seat belt warning system for passengers and a warning method thereof. In particular, when a passenger rides in a seat other than the driver's seat, whether the seat belt is automatically detected by the passenger and warns when the seat is not worn. The present invention relates to a passenger safety belt warning system and a warning method thereof.

일반적으로 안전벨트란 주로 항공기, 자동차 등 고속으로 달리는 교통기관의 좌석에 장착한 띠를 의미한다. 좌석벨트라고도 하며 승무원, 승객이 충돌이나 급브레이크, 또는 진동, 동요가 있을 때 좌석에서 튕겨져 나오거나 실내에 있는 돌기물에 부딪혀서 부상하는 것을 방지하기 위하여 설치된다.In general, the seat belt refers to a belt attached to the seat of the transportation system that runs at high speed, such as aircraft and automobiles. Also known as seat belts, it is installed to prevent crew members and passengers from injuring themselves from being thrown out of the seats or hitting the projections in the room in the event of a collision, sudden break, vibration or shaking.

본래는 상하동요가 심한 비행기, 그 중에서도 공중회전 등의 곡예비행을 하는 소형기, 전투기 등에서 조종사를 좌석에 묶는 것이었다. 그러나, 오늘날에는 자동차 도로가 정비됨에 따라 자동차가 고속화되어 교통사고 사망자 중 운전자가 차지하는 비율이 높아짐에 따라 운전자를 보호하기 위한 안전띠의 필요성이 요구되었다.Originally, pilots were tied to their seats in airplanes with heavy up-and-down fluctuations, especially small aeroplanes and fighters. However, as automobile roads are being repaired today, there is a need for safety belts to protect drivers as the speed of automobiles increases and the ratio of drivers to traffic accident deaths increases.

일반 자동차용 안전벨트는 천으로 되어 있는데, 간단히 끼웠다 벗었다 할 수 있는 버클이 달려 있다. 가장 간단한 구조의 것은 2점식인데, 띠의 양끝이 차체의 2개소에 고정되어 있고, 3점식은 운전자의 허리와 어깨를 거치게 되어 있으며, 띠의 끝이 차체의 3개소에 고정되어 있다.Seat belts for automobiles are made of cloth and have a buckle that can be easily inserted and removed. The simplest structure is a two-point type, with both ends of the belt fixed at two points on the body, the three-point type passing through the driver's waist and shoulders, and the ends of the belt fixed at three points on the body.

그러나, 종래의 안전벨트에 있어서는 운전석과 조수석의 안전벨트 착용을 확인하여 경고하는 기능만이 있으므로 뒷좌석의 승객의 경우 시트벨트를 착용했는지의 유무는 직접 뒷좌석을 봐야 알 수가 있다는 문제점이 있다. 또한, 고속 주행 중 안전벨트 착용 의무화가 운전자를 포함한 전체승객으로 확대됨에 따라서 특히 뒷좌석 승객들의 안전벨트 착용을 확인하는 것이 중요한 비중을 차지하게 되었다.However, in the conventional seat belts, only the function of confirming and warning the seat belts of the driver's seat and the front passenger's seat is warned. Therefore, the passenger of the rear seat has a problem of knowing whether the seat belt is worn by looking directly at the rear seat. In addition, as the mandatory wearing of seat belts during high-speed driving has been extended to all passengers including drivers, it is important to check the seat belts of the rear seat passengers.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 그 목적은 운전석과 조수석을 제외한 좌석에도 승객의 안전벨트 착용 여부를 감지하고 그에 따라 경고를 할 수 있도록 함으로서 운전자와 승객들에게 안전벨트의 착용을 유도할 수 있는 승객용 안전벨트 경고시스템 및 그 경고방법을 제공하는데 있다.The present invention has been made to solve the above-mentioned problems of the prior art, the object of which is to provide safety to the driver and passengers by detecting whether the seat belt is worn by the passenger in the seats other than the driver's seat and the passenger seat and warning accordingly. To provide a seat belt warning system for passengers and a warning method thereof which can induce wearing of the belt.
