Abstract

PURPOSE: A seatback frame structure of a bus is provided to minimize the injury of passengers though heads of passengers are bumped against a frame handle of a seatback. CONSTITUTION: A handle bar(2) is elastically installed in both tips of a seatback frame(3) through springs(4). The handle bar is made by a shock absorbing material. In a sudden stop or a crash accident, the handle bar absorbs shock by compressing the springs downward. Thereby, a head of a passenger is protected. Moreover, the injury of the head is minimized.

Description

승객보호용 버스의 시트백 프레임 구조{Seat Back Frame Structure of Bus for Passenger}Seat Back Frame Structure of Bus for Passenger Protection

본 발명은 버스, 예를 들어 시내버스에 설치되는 시트구조에 있어서 승객의 손잡이부분 역할도 수행하는 시트백 프레임구조에 관한 것으로, 더욱 상세하게는 급정지, 충돌 및 추돌사고와 같은 비상시 뒷좌석에 앉은 승객의 머리부분을 보호하여 상해치를 감소시킬 수 있는 승객 보호용 버스의 시트백 프레임구조에 관한 것이다.The present invention relates to a seat back frame structure that also serves as a handle part of a passenger in a seat structure installed in a bus, for example, a city bus, and more particularly, in the case of an emergency passenger such as a sudden stop, a collision and a collision accident. A seatback frame structure for a passenger protective bus that can reduce head injury by protecting the head.

일반적으로 시내버스의 승객용 시트는 시트레그와, 시트쿠션, 시트백 및 시트백 프레임으로 이루어져 있으며, 이중 시트백 프레임은 시트의 골격구조를 유지할 뿐만 아니라, 시트백의 상단부로 돌출되어 승객의 손잡이 기능 역할도 겸하고 있다.In general, the passenger seat of the city bus is composed of a seat leg, a seat cushion, a seat back and a seat back frame, and the double seat back frame not only maintains the structure of the seat but also protrudes into the upper part of the seat back to serve as a handle for the passenger. have.

즉 종래 시내버스에 장착되는 시트백의 시트프레임 구조는 도 4에 도시된 바와 같이 시트백(101)의 상단부로 시트백 프레임(103)이 연장되어 있는바, 이 시트백 프레임(103)은 시트의 골격구조를 유지하기 위해 통상 중공형태의 스틸파이프로 이루어짐에 따라 웬만한 큰하중에도 변형이 없는 튼튼한 구조로 되어 있다.That is, the seat frame structure of the seat back mounted on the conventional city bus is extended to the seat back frame 103 to the upper end of the seat back 101, as shown in Figure 4, the seat back frame 103 is a skeleton structure of the seat In order to maintain it, it is usually made of steel pipe of hollow form, so it has a strong structure without deformation even with a heavy load.

그러나 이와 같은 종래 시트백 프레임구조는 차량 급제동, 충돌 내지는 추락사고와 같은 비상상황시 뒷좌석에 앉아 있는 승객에게 치명적인 손상을 유발할 수 있는바, 즉 급정지시 승객은 엉덩이를 기준으로 상체가 회전운동을 하게 되는데, 이때 승객의 머리부분이 시트백 프레임(103)의 손잡이 부분(102)에 부딪혀 큰 상해를 당할 수 있으며, 더욱이 비상 상황시 대처능력이 떨어지는 노약자, 어린이 등에게는 더 큰 상해치를 초래할 수 있는 문제점이 있었다.However, such a conventional seatback frame structure may cause fatal damage to the passengers sitting in the rear seats in emergency situations such as vehicle braking, collision or fall accident, that is, when the emergency stops, the upper body rotates around the hips. In this case, the head of the passenger may be hit by the handle 102 of the seat back frame 103 to be injured, and furthermore, a problem that may cause more injuries to the elderly, children, etc., which is poor in handling in an emergency situation. there was.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 비상 상황시 뒷좌석에 앉은 승객 머리부분이 앞좌석의 시트백 프레임 손잡이 부분에 부딪히게 되어도 상해를 최소화시킬 수 있는 승객 보호용 버스의 시트백 프레임구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above conventional problems, the seat back frame of the passenger protective bus that can minimize the injury even if the passenger head sitting in the back seat hit the seat back frame handle portion of the front seat in an emergency situation The purpose is to provide a structure.

상기와 같은 목적을 달성하기 위한 본 발명은 시트의 골격을 이루면서 시트백의 상부로 돌출 연장된 손잡이바를 갖춘 시트백 프레임 구조에 있어서, 상기 손잡이바는 시트백 프레임의 양쪽 선단에서 스프링들을 매개로 설치되며, 이 손잡이바는 충격흡수용 부재로 이루어져 있다.In order to achieve the above object, the present invention provides a seat back frame structure having a handle bar that protrudes and extends to an upper portion of the seat back while forming a frame of the seat, wherein the handle bar is installed through springs at both ends of the seat back frame. The handle bar is made of a shock absorbing member.

이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 버스의 시트백 프레임 구조를 나타낸 제 1실시예 구성도이고, 도 2는 본 발명의 작동상태를 나타낸 설명도이다.1 is a configuration diagram of a first embodiment showing a seatback frame structure of a bus according to the present invention, and FIG. 2 is an explanatory diagram showing an operating state of the present invention.

본 발명은 시트의 골격을 이루면서 시트백(1)의 상부로 돌출 연장된 손잡이바(2)를 갖춘 버스차량용 시트백 프레임 구조에 있어서, 상기 손잡이바(2)는 시트백 프레임(3)의 양쪽 선단에서 스프링(4)들을 매개로 탄설 설치되어 있으면서 충격흡수용 재질로 되어 있다.The present invention provides a seat back frame structure for a bus vehicle having a handle bar (2) protruding and extending upward of the seat back (1) while forming a frame of the seat, wherein the handle bar (2) is spring at both ends of the seat back frame (3). (4) It is installed as a medium of coal shock absorbing material.

여기서 상기 손잡이바(2)는 변형이 가능한 합성수지 또는 고무재질과 같은 충격흡수용 재질로 되어 있기 때문에 승객의 손잡이 기능을 제공할 뿐만 아니라 승객의 머리부(5)가 이 손잡이바(2)에 부딪혔을 때 승객을 보호해주는 역할도 겸하도록 되어 있다.Since the handle bar 2 is made of a shock absorbing material such as a synthetic resin or rubber material that can be deformed, the handle bar 2 may not only provide a handle function of the passenger but also have the head 5 of the passenger hit the handle bar 2. It also serves to protect passengers.

한편 도 2에 도시된 바와 같이 버스운행시 급정지 내지는 충돌사고시 뒷좌석에 앉아 있는 승객의 머리가 상기 시트백 프레임(3)의 상단부인 손잡이바(2)에 부딪히게 되는바, 즉 승객은 엉덩이를 기준 상체가 회전 운동을 하게 되는데, 이때승객의 머리부(5)가 손잡이바(2)에 부딪힐 때 이 손잡이바(2)는 스프링(4)을 압축시키면서 화살표 방향인 하방향으로 이동하면서 충격을 흡수하도록 되어 있다.Meanwhile, as shown in FIG. 2, the head of the passenger sitting in the rear seat during a sudden stop or crash in a bus driving hits the handle bar 2, which is the upper end of the seatback frame 3, that is, the passenger is referred to the upper body based on the hip. When the passenger's head 5 hits the handlebar 2, the handlebar 2 absorbs the shock while moving downward in the direction of the arrow while compressing the spring 4. It is supposed to be.

이와 같이 본 발명은 손잡이바(2)의 운동에너지를 스프링(4)이 변형에너지로 흡수하여 승객의 머리손상을 최소화시키도록 되어 있다.Thus, the present invention is to minimize the damage to the passenger's head by absorbing the kinetic energy of the handle bar (2) as the strain energy.

한편, 도 3은 본 발명의 다른 실시예를 도시한 것으로, 시트백 프레임(3)의 상단에 쿠션부(6)를 갖춘 손잡이바(2)를 설치한 것으로, 이 손잡이바(2)도 변형이 가능한 합성수지 또는 고무재질로 형성된 충격흡수용 재질로 되어 있다.On the other hand, Figure 3 shows another embodiment of the present invention, which is provided with a handle bar (2) having a cushion portion (6) on the upper end of the seat back frame (3), the handle bar (2) is also modified It is made of shock absorbing material made of synthetic resin or rubber material.

상기와 같이 본 발명에 다른 승객보호용 버스의 시트백 프레임구조는 승객의 손잡이 기능뿐만 아니라 비상 상황시 승객의 머리부 상해치를 저감시킬 수 있는 보호기능도 갖추고 있다.As described above, the seat back frame structure of the bus for passenger protection according to the present invention is provided with a protection function to reduce the head injury value of the passenger in an emergency as well as the handle function of the passenger.
