The invention relates to a rail arrangement (14) for a seat longitudinal adjustment device (10) of a vehicle seat (2), comprising a lower rail (16) for fastening to a vehicle floor and an upper rail (18) inserted in the lower rail in a form-fitting manner for coupling to the vehicle seat (2), the upper rail (18) having a plurality of load rollers (42) by means of which the upper rail (18) can be moved relative to the vehicle seat (2). The upper rail (18) is mounted on a rail base (22) of the lower rail (16) so as to be displaceable in a rail longitudinal direction (L), the lower rail (16) having a profiled longitudinal slot (26), the lower rail (16) and the upper rail (18) having interlocking contours (28, 34) which engage in a staggered manner, the interlocking contours (34) of the upper rail (18) passing through an overload roller (42), and the overload roller (42) passing through the profiled longitudinal slot (26). The lower rail (16) has at least one load roller (42), and in the region of each load roller (42) has a through opening (48) through which the load roller (42) at least partially passes or which can be passed under load, and wherein the lower rail (16) has a support edge (50) facing the rail base (22), which support edge is arranged aligned with the load roller (42) in the rail height direction (H).
本发明涉及用于车辆座椅(2)的座椅纵向调节装置(10)的轨道组件(14),轨道组件具有用于紧固在车辆地板上的下轨道(16)和形状锁合地置入在下轨道中的用于与车辆座椅(2)耦联的上轨道(18),其中,上轨道(18)具有多个负载辊(42),借助这些负载辊,上轨道(18)以能沿轨道纵向方向(L)移动运动的方式支承在下轨道(16)的轨道底部(22)上,其中,下轨道(16)具有型材纵向缝隙(26),其中,下轨道(16)和上轨道(18)具有交错嵌接的形状锁合轮廓(28、34),其中,上轨道(18)的形状锁合轮廓(34)穿越过负载辊(42),并且在负载辊(42)的区域中分别具有贯穿开口(48),贯穿开口被负载辊(42)至少部分穿过或在负载情况下是可穿过的,并且其中,下轨道(16)具有朝向轨道底部(22)的支撑边缘(50),支撑边缘在轨道高度方向(H)上与负载辊(42)对齐地布置。
