본 고안은 자동차용 시트 트랙(seat track)에 관한 것으로, 보다 상세하게는 상ㆍ하부레일의 단면구조를 개선하여 슬라이딩을 원활하게 하고 록킹을 안정되게함과 아울러 상기 상ㆍ하부레일이 외부의 충격으로부터 이탈되는 것을 방지하여 승객의 안전을 도모하는 자동차용 시트 트랙에 관한 것이다.The present invention relates to a seat track for automobiles, and more particularly, to improve the cross-sectional structure of the upper and lower rails, to facilitate sliding, to stabilize the locking, and to allow the upper and lower rails to be impacted externally. The present invention relates to a seat track for an automobile that prevents the vehicle from falling off and promotes safety of the passenger.

일반적으로 자동차의 시트 트랙은 시트를 전ㆍ후 슬라이딩 가능하게하여 승객의 체형에 따라 그 조정을 가능하도록 하여서 실내공간등을 적절하게 활용하도록 하는데 그 목적을 갖는 것이다.In general, the seat track of an automobile has the purpose to allow the seat to be slidable before and after, so that the seat can be adjusted according to the passenger's body shape so as to properly utilize the interior space.

제1도는 종래의 자동차용 시트 트랙을 단면도로 도시한 것이다.1 is a cross-sectional view of a conventional vehicle seat track.

시트브래킷(50)이 상부레일(52)의 일측에 용접고정되고 상부레일(52)의 양측이 만곡되어 이루어진 가이드부(52a)와 하부레일(54)의 양측이 상기 상부레일(52)의 가이드부(52a)와 대향되게 형성된 가이드부(54a)에 볼(56)을 형성하고 중앙에는 롤러(58)를 형성하여 상부레일(52)이 하부레일(54)에서 전ㆍ후슬라이딩 가능하게 형성하며, 하부레일(54)의 중앙 하단에는 다수개의 로커홀(60a)을 갖는 로커플레이트(60)가 리벳(62)으로 결합되고 상기 상부레일(52)의 일측에 형성된 가이드플랜지(64)에 로커(66)가 형성되어 이 로커(66)의 작동에 의해 시트 트랙의 전ㆍ후이송을 가능하게 구성한 것이다.The seat bracket 50 is welded and fixed to one side of the upper rail 52 and both sides of the upper rail 52 are curved, so that both sides of the guide part 52a and the lower rail 54 are guides of the upper rail 52. A ball 56 is formed in the guide portion 54a formed to face the portion 52a, and a roller 58 is formed at the center thereof so that the upper rail 52 is formed to be able to slide forward and backward on the lower rail 54. The rocker plate 60 having a plurality of rocker holes 60a is coupled to the rivet 62 at the center lower end of the lower rail 54, and the rocker plate is formed on the guide flange 64 formed at one side of the upper rail 52. 66) is formed to enable forward and backward transfer of the seat track by the operation of the rocker 66.

상기와 같이 구성된 종래의 시트 트랙의 구조에 의하면 다음과 같은 문제점이 있다.According to the structure of the conventional seat track configured as described above, there are the following problems.

첫째, 차량이 외부로부터의 충돌시 시트에 충격이 가해지면 시트가 뒤로 들리려는 힘이 작용하여 상부레일(52)의 만곡된 가이드부(52a)가 벌려지면서 하부레일(54)이 이탈되는 상황이 발생하여서 안전사고의 위험이 따르고, 둘째, 로커플레이트(60)가 하부레일(54)에 별도로 조립되어 제품의 두께가 두꺼워지고 부품수의 증가로 중량이 무거우며 제조원가의 상승요인이 되며, 셋째, 하부레일에 리벳팅된 로커플레이트가 충돌 등에 의한 외부의 충격이 가해지면 리벳부위에서 변형이 발생되어 로커의 록킹상태가 불안정하며, 아울러 시트 트랙의 고정상태를 견고하게 할 수 없는 문제점이 있는 것이다.First, when the impact is applied to the seat when the vehicle is impacted from the outside, a force to lift the seat back acts so that the curved guide portion 52a of the upper rail 52 opens and the lower rail 54 is separated. Second, the rocker plate 60 is assembled separately to the lower rail 54, resulting in a thicker product and a heavier weight due to an increase in the number of parts, and a rise in manufacturing cost. When the rocker plate riveted to the lower rail is subjected to an external impact due to a collision or the like, deformation occurs in the riveting part, so that the locking state of the rocker is unstable, and there is a problem in that the seat track cannot be firmly fixed.

본 고안은 상기와 같은 종래 기술의 문제점을 해결하기 위해 창안한 것으로, 시트 트랙의 전ㆍ후이동을 원활하게 하고 종래와 같은 로커플레이트를 삭제하여 구조를 간단히 하며 부품수를 간단히 하여 제조원가를 절감할 수 있도록 하는 자동차용 시트 트랙을 제공하는데 그 목적이 있다.The present invention was devised to solve the above problems of the prior art, which facilitates the front and rear movement of the seat track, eliminates the rocker plate as in the prior art, simplifies the structure, and reduces the manufacturing cost by simplifying the number of parts. It is an object of the present invention to provide a seat track for automobiles.

상기의 목적을 실현하기 위한 본 고안은 절곡된 시트브래킷과 연장되어 형성된 상부레일은 그 양측으로 만곡되어 가이드부가 형성되고 상기 상부레일의 가이드부와 대향되게 만곡된 가이드부를 갖는 하부레일을 형성하여 이들 사이에 볼과 롤러를 개재하여 상부레일이 하부레일에서 전ㆍ후이동을 가능하게 하고, 상기 하부레일의 경사부에는 다수개의 로커홀을 형성하며 상기 시트브래킷의 일측에 고정된 지지편에 레버를 회전가능하게 고정하고 레버에는 로커와 토션스프링을 형성하여 레버에 의해 작동되는 로커가 하부레일의 경사부에 형성된 로커홀에 걸려 상부레일의 전ㆍ후이동이 제한되게 한 것이다.The present invention for realizing the above object is to form a lower rail having a guide portion bent to the guide rail of the upper rail is formed in the upper rail is formed extending to the both sides of the bent seat bracket and the guide portion of the upper rail The upper rail allows the front rail to move forward and backward from the lower rail through a ball and a roller in between. A plurality of rocker holes are formed in the inclined portion of the lower rail, and a lever is supported on a support piece fixed to one side of the seat bracket. It is fixed rotatably and the torsion spring is formed in the lever so that the rocker operated by the lever is caught in the rocker hole formed in the inclined portion of the lower rail so that the front and rear movement of the upper rail is restricted.

이하, 본 고안의 바람직한 실시예를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings a preferred embodiment of the present invention as follows.

제2도는 본 고안의 시트 트랙의 사시도이고, 제3도는 제2도의 작용상태의 단면도를 도시한 것이다.FIG. 2 is a perspective view of the seat track of the present invention, and FIG. 3 is a sectional view of the working state of FIG.

상부가 절곡된 시트브래킷(10)과 연장되어 형성된 상부레일(12)은 그 양측으로 만곡된 가이드부(12a)가 형성되고 상기 상부레일(12)의 가이드부(12a)와 대향되는 위치에 만곡된 가이드부(14a)를 갖는 하부레일(14)을 형성하여 이들 사이에 볼(16)과 중앙에 롤러(18)를 개재하여 상부레일(12)이 하부레일(14)에서 전ㆍ후이동을 가능하게 형성하고, 상기 하부레일(14)의 일측으로 형성된 경사부(14b)에는 다수개의 로커홀(14c)을 형성하며 상기 시트브래킷(10)의 일측에 고정된 지지편(20,22)에 레버(24)를 회전가능하게 고정하고 레버(24)에는 지지편(22)의 사이에 로커(26)를 회전가능하게 고정하고 그 단부에 토션스프링(28)을 형성하여 레버(24)에 의해 작동되는 로커(26)가 하부레일(14)의 경사부(14b)에 형성된 로커홀(14c)에 걸려 상부레일(12)의 전ㆍ후이동이 제한되게 구성한 것이다. 도면중 미설명부호 30은 레버(24)의 회동을 제한하는 스토퍼, 32,34는 보디브래킷, 36은 리테이너를 도시한 것이다.The upper rail 12 formed by extending the upper and lower seat brackets 10 is formed with guide portions 12a curved at both sides thereof and curved at positions opposite to the guide portions 12a of the upper rail 12. A lower rail 14 having a guide portion 14a formed therebetween, and the upper rail 12 moves forward and backward on the lower rail 14 through a ball 16 and a roller 18 in the center therebetween. A plurality of rocker holes 14c are formed in the inclined portion 14b formed to one side of the lower rail 14, and supported on the support pieces 20 and 22 fixed to one side of the seat bracket 10. The lever 24 is rotatably fixed, the locker 26 is rotatably fixed to the lever 24 between the support pieces 22, and a torsion spring 28 is formed at the end thereof by the lever 24. The locker 26 being operated is caught by the rocker hole 14c formed in the inclined portion 14b of the lower rail 14 so that the front and rear movement of the upper rail 12 is limited. to be. In the figure, reference numeral 30 denotes a stopper for limiting the rotation of the lever 24, 32 and 34 represent a body bracket, and 36 represents a retainer.

상기와 같이 구성된 본 고안에 의하면 상ㆍ하부레일(12,14)에 개재된 볼(16) 및 롤러(18)에 의하여 상부레일(12)의 전ㆍ후이동이 원활하게 이루어지는 효과를 가지게 되고 하부레일(14)에 일체로 형성된 로커홀(14c)에 의해 로커(26)의 록킹상태를 견고하게 유지시킬 수 있으며, 충돌시 비틀림에 대한 강성이 우수하여 시트 트랙의 안전성을 갖게 되고, 아울러 부품수가 절감되어 중량의 감소효과를 가져오게 되며 두께를 줄일 수 있어 제조원가를 절감시키게 되는 것이다.According to the present invention configured as described above has the effect that the front and rear movement of the upper rail 12 smoothly by the ball 16 and the roller 18 interposed on the upper and lower rails (12,14) and the lower The rocker hole 14c formed integrally with the rail 14 can maintain the locked state of the rocker 26. The rigidity against torsion in the event of a collision makes the seat track safe and the number of parts It is reduced to bring about a weight reduction effect and to reduce the thickness to reduce the manufacturing cost.

이상에서와 같이 본 고안의 자동차용 시트 트랙에 의하면 상ㆍ하부레일의 단면구조를 개선하여 상부레일의 원활한 이동과 외부의 충격으로부터 강성을 유지하게 되고 부품의 단순화로 제품의 불량률 감소와 재료비용을 절약하는 효과를 가지게 되는 것이다.As described above, according to the automobile seat track of the present invention, the cross-sectional structure of the upper and lower rails is improved to maintain rigidity from the smooth movement of the upper rails and external shocks, and to reduce the defect rate of the product and the material cost by simplifying parts. It will have a saving effect.
