The invention relates to a longitudinal adjustment device for a vehicle seat having a floor rail (20), a seat rail (22), and a locking unit (28), which is substantially accommodated in a cavity (26) formed by the two rails. The locking unit has a housing (30), a bearing shaft (32), which is arranged in the housing (30) and extends in the sliding direction (24), at least two flat blocking parts (36), which are arranged to pivot around the bearing shaft (32) independently of each other and which are elastically preloaded independently of each other by means of respective blocking springs (34), and a releasing part (38). The structurally identical blocking parts (36) each have a first arm (40) and a second arm (42), between which the bearing shaft (32) is located. The seat rail (22) has, foreach blocking part, a first shear slot (48), which receives the first arm (40), and a second shear slot (50), which receives the second arm (42). The floor rail (20) has a first hole strip (52), whichcooperates with the first arms (40) and has first blocking slot (56), which are arranged one following the other periodically in the sliding direction (24), and a second hole strip (54), which cooperates with the second arms (42) and has second blocking slots (58), which are arranged one following the other periodically in the sliding direction (24).

    本发明涉及用于车辆座椅的纵向调节装置,其具有地板导轨(20)、座椅导轨(22)和基本容纳在由两个导轨形成的腔体(26)中的锁定单元(28)。锁定单元具有壳体(30)、布置在所述壳体(30)中且沿滑动方向(24)延伸的轴承轴(32)、布置成彼此独立绕轴承轴(32)枢转并由相应的阻挡弹簧(34)彼此独立地弹性预加载的至少两个平坦阻挡件(36)、以及释放件(38)。结构相同的阻挡件(36)分别具有轴承轴(32)位于其间的第一臂(40)和第二臂(42)。座椅导轨(22)对于每个阻挡件具有接纳第一臂(40)的第一剪切槽(48)和接纳第二臂(42)的第二剪切槽(50)。地板导轨(20)具有与第一臂(40)协配并具有沿滑动方向(24)周期性地一个布置在另一个之后的第一阻挡槽(56)的第一穿孔条(52)以及与第二臂(42)协配并具有沿滑动方向(24)周期性地一个布置在另一个之后的第二阻挡槽(58)的第二穿孔条(54)。
