본 발명은 테더 앵커 강도 시험 시, 리어시트 마운팅부 강성 증대 구조에 관한 것으로서, 더욱 상세하게는 리어시트 벨트의 테더 앵커가 장착되는 부위의 구조가 패널 하단에 크로스 멤버와 보강판이 서로 용접되어 있는 바, 상기 크로스 멤버의 안쪽 양측면에 3면 지지 방식의 'ㄷ'자 형상의 보강판을 용접함으로써, 기존 대비, 리어 플로워 패널의 상단 수평면과 크로스 멤버 전후 수직면의 지지 강성을 더욱 증대시켜 테더 앵커의 강도 시험을 만족하고, 그로인해 승객의 안전성을 확보할 수 있는 테더 앵커 강도 시험 시, 리어시트 마운팅부 강성 증대 구조에 관한 것이다.The present invention relates to a structure for increasing the rigidity of the rear seat mounting portion when testing the tether anchor strength, and more particularly, the cross member and the reinforcement plate are welded to each other at the bottom of the panel in the structure where the tether anchor of the rear seat belt is mounted. By welding a three-sided 'c' shaped reinforcement plate on both inner side surfaces of the cross member, the rigidity of the tether anchor is further increased by supporting the rigidity of the upper horizontal surface of the rear follower panel and the vertical surface before and after the cross member compared to the existing one. The present invention relates to a structure for increasing stiffness of the rear seat mounting portion when testing a tether anchor strength that satisfies the test and thereby ensures passenger safety.

일반적으로, 종래의 시트벨트는 차량 충돌사고 발생시 운전자 또는 탑승객을 구속시켜 차량의 크래쉬 패드에 부딪힘 또는 차량 외부로 튕겨져 나오는 것을 방지할 수 있도록 한 것이다.In general, the conventional seat belt is to restrain the driver or passengers in the event of a vehicle crash to prevent from hitting the vehicle's crash pad or bounced out of the vehicle.

이와 같은 시트벨트는 탑승객의 허리만을 감싸도록 된 2 점식 시트벨트와, 탑승객의 허리와 흉부를 감싸며 구속시키도록 된 3점식 시트벨트가 있으며 일반 승용차량의 경우에는 주로 3점식 벨트가 많이 사용되고 있다.Such a seat belt has a two-point seat belt to cover only the waist of the passenger, and a three-point seat belt to wrap and restrain the waist and chest of the passenger, and in the case of a general passenger vehicle, a three-point belt is mainly used.

한편, 종래의 리어시트의 시트벨트는 3개의 벨트 선단이 테더 앵커와 결합하여 각각 좌우측과 중앙에 볼트 고정되어 있다.On the other hand, the seat belt of the conventional rear seat is bolted to the left and right and the center of the three belt front end is combined with the tether anchor, respectively.

이때, 중앙의 시트벨트의 테더 앵커는 도 3에 도시된 바와 같이, 리어시트마운팅부인 리어 플로워 패널(130) 하단에 크로스 멤버(120)와 플레이트형 보강판(140)이 상하방향으로 점용접되어 있어 테더 앵커 강도 시험 시, 자동차 충돌사고와 동일하게 앞쪽 상방으로 경사지게 당기면 크로스 멤버(120)의 후방 플랜지(121)의 용접부위가 파단이 발생하여 승객의 안전성에 심각한 문제가 일어날 수 있다.At this time, as shown in Figure 3, the tether anchor of the center seat belt, the cross member 120 and the plate-shaped reinforcement plate 140 is spot welded in the vertical direction at the bottom of the rear floor panel 130 that is the rear seat mounting portion Therefore, in the test of the tether anchor strength, the same as the car crash accidentally pulled upwards inclined upwards, the welding portion of the rear flange 121 of the cross member 120 may cause a serious problem in the safety of the passengers.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, 리어시트 벨트의 테더 앵커가 장착되는 부위의 구조가 패널 하단에 크로스 멤버와 보강판이 서로 용접되어 있는 바, 상기 크로스 멤버의 안쪽 양측면에 'ㄷ'자 형상의 보강판을 용접함으로써, 기존 대비, 리어 플로워 패널의 상단 수평면과 크로스 멤버 전후 수직면의 지지 강성을 더욱 증대시켜 테더 앵커의 강도 시험을 만족하고, 그로인해 승객의 안전성을 확보할 수 있는 테더 앵커 강도 시험 시, 리어시트 마운팅부 강성 증대 구조를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the structure of the site where the tether anchor of the rear seat belt is mounted, the cross member and the reinforcement plate are welded to each other at the bottom of the panel, both sides of the inner side of the cross member By welding the reinforcement plate of the '-' shape, the rigidity of the upper horizontal surface of the rear floor panel and the vertical surface before and after the cross member is further increased to satisfy the strength test of the tether anchor, thereby securing passenger safety. In order to test the tether anchor strength, the purpose of the present invention is to provide a structure for increasing the rigidity of the rear seat mounting portion.

이하, 첨부도면을 참조하여 본 발명의 구성에 대해 상세하게 설명하면 다음과 같다.Hereinafter, the configuration of the present invention with reference to the accompanying drawings in detail.

도 1은 본 발명에 따른 테더 앵커 강도 시험 시, 리어시트 마운팅부 강성 증대 구조를 나타내는 분해 사시도이고, 도 2는 본 발명에 따른 테더 앵커 강도 시험 시, 리어시트 마운팅부 강성 증대 구조를 나타내는 단면도이며, 도 3은 테더 앵커 강도 시험 시, 변위 및 하중을 나타내는 곡선도이다.1 is an exploded perspective view showing the rear seat mounting portion stiffness increase structure during the tether anchor strength test according to the present invention, Figure 2 is a cross-sectional view showing a rigid seat mounting portion increase structure during the tether anchor strength test according to the present invention. 3 is a curve diagram showing displacements and loads when testing the tether anchor strength.

도 1에 도시된 바와 같이, 리어 시트벨트의 테더 앵커(10)가 장착되는 부위는 차체 프레임(11)을 크로스하여 장착되며 양단에 플랜지(12a)가 구비된 'U자' 형상의 크로스 멤버(12)가 구비되어 있고, 상기 크로스 멤버(12)의 상단부에 리어 플로워 패널(13)이 장착된다.As shown in FIG. 1, a portion in which the tether anchor 10 of the rear seat belt is mounted is mounted by crossing the body frame 11 and has a 'U' shape cross member having flanges 12a at both ends ( 12 is provided, and the rear floor panel 13 is mounted on the upper end of the cross member 12.

이때, 상기 테더 앵커(10)의 고정 브라켓(10a)이 볼트 고정되는 부위의 리어 플로워 패널(13)은 패널 구멍(13a)이 형성되어 있고, 상기 크로스 멤버(12)와 리어 플로워 패널(13) 사이에 융착 고정되는 보강판(14)이 형성되어 있는 바, 상기 보강판(14)은 90도 각도로 절곡된 측판(14a, 14b)이 구비된 역'U'자 형상으로서, 크로스 멤버(12)의 안쪽 양측면에 융착 고정된다.In this case, a panel hole 13a is formed in the rear follower panel 13 where the fixing bracket 10a of the tether anchor 10 is bolted, and the cross member 12 and the rear follower panel 13 are formed. The reinforcing plate 14 is fusion-fixed therebetween, and the reinforcing plate 14 is an inverted 'U' shape having side plates 14a and 14b bent at an angle of 90 degrees, and has a cross member 12. Is fixed on both sides of the inner side.

이와 같이, 융착 고정된 보강판(14)은 크로스 멤버(12)에 양면이 고정되고, 상면이 리어 플로워 패널(13)에 지지되는 3면 지지 방식으로서, 테더 앵커 강도 시험 시, 자동차 충돌사고와 동일하게 앞쪽 상방으로 경사지게 당기면, 종래기술에 비해서 더욱 향상된 지지 강성을 이룰 수 있는 것을 보여준다.As described above, the fusion-fixed reinforcing plate 14 is a three-sided support system in which both sides are fixed to the cross member 12 and the upper surface is supported by the rear follower panel 13. Similarly, pulling forward obliquely upwards shows that more improved support stiffness can be achieved compared to the prior art.

도 3은 테더 앵커 강도 시험 시, 도 2에 보인 경사 방향의 하중에 대한 리어 시트벨트의 변위를 나타내는 곡선도로서, 종래 기술 대비, 동일한 하중에서 시트벨트가 당겨지는 변위가 작게 나타나므로 동일한 하중에서 리어 플로워 패널(13)의 상단 수평면과 크로스 멤버(12) 전후 수직면의 지지 강성을 더욱 증대시킬 수 있다.FIG. 3 is a curve diagram showing the displacement of the rear seat belt with respect to the load in the inclined direction shown in FIG. 2 during the test of the tether anchor strength. The support rigidity of the upper horizontal surface of the rear follower panel 13 and the vertical surface before and after the cross member 12 can be further increased.

상술한 바와 같이, 본 발명에 따르면, 기존의 플레이트형 보강판을 3면 지지용 'ㄷ'자형 보강판으로 대체함으로써, 후방 용접면이 탈거되는 것을 방지하고, 리어 플로워 패널의 상단 수평면과 크로스 멤버 전후 수직면의 지지 강성을 더욱 증대시켜 테더 앵커의 강도 시험을 만족하고, 그로인해 승객의 안전성을 확보할 수 있는 효과가 있다.As described above, according to the present invention, by replacing the existing plate-shaped reinforcement plate with a three-sided '' 'shaped reinforcement plate, to prevent the rear welding surface is removed, the upper horizontal surface and the cross member of the rear floor panel The support rigidity of the front and rear vertical surfaces is further increased to satisfy the strength test of the tether anchor, thereby ensuring the safety of the passengers.
