본 발명은 서브머린 방지 구조를 갖는 차량 리어시트의 시트프레임에 관한 것이다.The present invention relates to a seat frame of a vehicle rear seat having a submarine prevention structure.

통상적으로 서브머린 현상은 차량의 급정차 시, 전방 측으로 쏠리는 승객으로부터 전달되는 하중에 의해 도1에 'A'로 표시된 리어시트(1)의 전방부가 압축되 어 승객이 시트벨트 아래로 빠져나가는 것을 말한다.In general, the submarine phenomenon indicates that the front part of the rear seat 1, denoted as 'A' in FIG. 1, is compressed by the load transmitted from the passenger pulled toward the front side when the vehicle is stopped suddenly and the passengers exit under the seat belt. Say.

따라서, 서브머린 현상을 방지하기 위하여는 리어시트 전방측에 승객이 전방측으로 미끌어져 나가지 않도록 하기 위한 서브머린 방지구조가 강구될 필요가 있는데, 종래에는 서브머린 방지구조로서 차체패널에 돌출턱을 마련하여 리어시트 전방측이 들려지도록 구성하고 있었다. 그러나, 이와 같은 돌출턱에 의한 서브머린 방지성능은 만족스럽지 못한 측면이 있었으며, 서브머린을 방지하기 위한 형상 선택의 자유도가 높지 않으며 돌출턱의 설치를 위한 별도의 작업 및 부재를 필요로 하는 문제점이 있었다.Therefore, in order to prevent the submarine phenomenon, it is necessary to provide a submarine prevention structure to prevent the passengers from slipping to the front side on the rear seat front side. Conventionally, a protruding jaw is provided on the vehicle body panel as a submarine prevention structure. The rear seat front side was lifted up. However, there was an unsatisfactory aspect of the anti-submarine performance by the protruding jaw, the degree of freedom of shape selection for preventing the submarine is not high, and the problem of requiring a separate work and a member for the installation of the protruding jaw is problematic. there was.

한편, 리어시트는 승객이 앉게 되는 시트쿠션과 그 하부에 설치되어 리어시트를 지지하기 위한 시트프레임 및 패드로 구성되는데, 서브머린 방지구조는 강성을 갖는 시트프레임에 직접 마련될 수도 있다.On the other hand, the rear seat is composed of a seat cushion seated by the passenger and a seat frame and a pad for supporting the rear seat, the submarine prevention structure may be provided directly to the seat frame having rigidity.

그러나, 도2 및 도3에 도시된 바와 같이, 현재 제작되고 있는 시트프레임(2)은 와이어를 좌우로 엮은 프레임 구조로 이루어져 있어 서브머린 방지구조를 시트프레임(2)에 적용하고자 하는 경우, 와이어의 사용량이 증가할 뿐만 아니라 각 와이어 간의 용접(3)을 위한 작업공수가 상당히 늘어나게 되어 비용을 증가시킬 뿐만 아니라 생산성이 좋지 않다는 문제점이 있다. 물론 차량의 중량을 증가시키는 원인이 되기도 한다.However, as shown in FIGS. 2 and 3, the sheet frame 2 currently manufactured has a frame structure in which wires are woven to the left and right, so that the submarine preventing structure is applied to the sheet frame 2, the wire Not only does the usage increase, but also the workmanship for welding (3) between each wire is significantly increased, not only increases the cost but also has a problem that the productivity is not good. Of course, this also increases the weight of the vehicle.

또한, 와이어로 엮은 종래의 시트프레임(2)은 패드(4)와 함께 인서트 성형되는데, 강성을 위해 와이어를 촘촘히 엮은 경우 패드(4) 원료의 흐름을 저하로 인한 성형불량의 발생시키며, 나아가 인서트 성형 및 이후 공정에서 불량이 발생될 경우 불량제품의 재활용을 위해 시트프레임(2)과 패드(4)를 서로 분리하기 어렵다는 문제점이 있다.In addition, the conventional seat frame (2) woven with wire is insert-molded together with the pad (4), when tightly woven wire for rigidity, the molding failure occurs due to a decrease in the flow of raw material of the pad (4), further inserts If a defect occurs in the molding and subsequent processes, there is a problem in that it is difficult to separate the seat frame 2 and the pad 4 from each other in order to recycle the defective product.

본 발명은 이러한 문제점을 해결하기 위하여 제안된 것으로, 생산성이 우수할 뿐만 아니라 중량절감이 가능하며 패드와의 조립성 및 재활용성이 우수한 시트프레임을 제공함을 목적으로 한다.The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a seat frame which is not only excellent in productivity but also capable of weight reduction and excellent assembly property and recyclability with a pad.

상기의 목적을 달성하기 위한 본 발명에 따른 리어시트의 시트프레임은, 유리섬유매트 강화 플라스틱(Glass Mat Thermoplastic: GMT)을 프레스 성형하여 제조되어 패드에 조립되며, 전방측에는 서브머린 현상을 방지하기 위한 돌출부가 마련된 것을 특징으로 한다.The seat frame of the rear seat according to the present invention for achieving the above object is manufactured by press-molding Glass Mat Thermoplastic (GMT) is assembled to the pad, the front side for preventing the submarine phenomenon It is characterized in that the protrusion is provided.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 따른 리어시트의 시트프레임에 대하여 살펴본다.Hereinafter, with reference to the accompanying drawings looks at with respect to the seat frame of the rear seat in accordance with a preferred embodiment of the present invention.

도4에 도시된 바와 같이, 리어시트 시트프레임(10)의 후방측에는 승객의 엉덩이 부분이 안착되는 안착홀(12)이 마련되며, 그 전방측에는 안착홀(13) 부위에 안정적으로 앉아 있던 승객이, 차량 충돌사고 등에 의한 급정차로 인해 전방측으로 쏠리게 될 때 시트벨트(미도시)를 착용하고 있음에도 불구하고 리어시트를 이탈하게 되는 서브머린 현상을 방지하기 위한 돌출턱(11)이 형성되어 있다.As shown in Figure 4, the rear seat seat frame 10 is provided with a seating hole 12 for seating the hips of the passenger is seated, the front side of the passenger seated stably in the seating hole (13) Protrusion jaw 11 is formed to prevent the submarine phenomenon that the rear seat is separated even though the seat belt (not shown) is worn in the front side due to a sudden stop due to a vehicle collision accident.

돌출턱(11)은 전방측이 가장 높고 후방측이 낮아지는 형태로 형성되는데, 성형성 향상 및 중량경감을 위해 복수개의 홈부(12)가 마련된다.Protruding jaw (11) is formed in the form that the front side is the highest and the rear side is lowered, a plurality of grooves 12 are provided for improving moldability and weight reduction.

서브머린 현상의 방지에 있어 돌출턱(11)의 강도 및 형상이 중요한데, 본 발명에 따른 시트프레임(10)은 프레스 성형가공에 의해 제작되기 때문에 이 두가지의 요건을 모두 충족시킨다. 뿐만 아리나, 경량화도 가능하다.In the prevention of the submarine phenomenon, the strength and shape of the protruding jaw 11 are important. Since the seat frame 10 according to the present invention is manufactured by press forming, both of these requirements are satisfied. Also, it is possible to reduce weight.

또한, 시트프레임(10)은, 도5에 도시된 바와 같이, 프레스 성형에 의해 별도로 제작된 후 패드(20)에 조립된다. 따라서, 시트프레임과 패드를 함께 인서트 성형함에 의해 발생되던, 성형불량 및 생산성 저하의 문제가 해소될 수 있으며, 불량발생 시 시트프레임(10)을 패드(20)로부터 분리하여 재활용하기 편리하다.In addition, as shown in FIG. 5, the seat frame 10 is separately manufactured by press molding and then assembled to the pad 20. Therefore, the problem of poor molding and reduced productivity, which is caused by insert molding the seat frame and the pad together, can be solved, and when the defect occurs, the seat frame 10 is conveniently separated from the pad 20 and recycled.

한편, GMT는 유리섬유매트와 수지층이 수개의 층으로 적층되어 있으며 부분적으로 단방향 보강이 가능한 특징이 복합재로서, 이러한 GMT에 관한 기술은 스위스의 쿼드란트(Quadrant)나 미국의 아즈델(Azdel)사의 특허에 의해 잘 알려져 있다. GMT 성형공정은 이미 공지된 것으로 그 설명은 생략한다.Meanwhile, GMT is a composite material in which a glass fiber mat and a resin layer are laminated in several layers, and can be partially unidirectionally reinforced. Such a technology for GMT is Quadrant of Switzerland or Azdel of USA. It is well known by the patent. The GMT molding process is already known and description thereof is omitted.

상술한 바와 같은 구조로 이루어진 리어시트의 시트프레임은, GMT의 프레스 성형가공에 의해 제작되기 때문에 생산성 및 강도가 우수할 뿐만 아니라 중량의 경감이 가능하며, 패드와의 조립성 및 재활용성이 우수하다.The seat frame of the rear seat having the structure as described above is produced by GMT press molding, so that not only is it excellent in productivity and strength, but also it is possible to reduce weight, and is excellent in assembling and recyclability with the pad. .
