The invention relates to an adjusting device (103) for longitudinally adjusting a vehicle seat, comprising: at least one rail pair having a fixed first rail (3) and a second rail (5) which is guided so as to be movable in a longitudinal direction (x) relative to the first rail; and an additional locking mechanism (107) having a plurality of first locking structures (24, 25), which are formed on or connected to the second rail (5), and a plurality of second locking structures (36, 37), which are formed corresponding to the first locking structures and are formed on or connected to the first rail (3). The additional locking mechanism is normally inactive and, after the force is introduced in the event of a crash, the force is released by means of the locking structure (24, 25; 36, 37) brings about an additional locking of the second rail (5) with the first rail (3). In order to ensure that the longitudinal position of the pair of seat rails is locked by additional locking in any longitudinal position in the event of a crash, the first and second locking structures (24, 25; 36, 37) are arranged on both sides of the respective rail pair and are arranged at a regular distance (a) from each other in the longitudinal direction (x), the first locking structures (24a, 25a; 24b, 25b) or the second locking structure (36a, 37b; 36b, 37b) are arranged offset from one another in the longitudinal direction (x).

    本发明公开了一种用于纵向调节车辆座椅的调节装置(103),该调节装置包括:至少一个轨道对,该轨道对带有方位固定的第一轨道(3)和以能在纵向方向(x)上相对第一轨道运动的方式受导引第二轨道(5);和附加锁定机构(107),该附加锁定机构具有多个第一锁定结构部(24、25)和多个第二锁定结构部(36、37),第一锁定结构部构造在第二轨道(5)上或者与第二轨道连接,第二锁定结构部与第一锁定结构部对应地构造并且构造在第一轨道(3)上或者与第一轨道连接。附加锁定机构在正常情况下是不起作用的并且在碰撞情况下的力导入后通过锁定结构部(24、25;36、37)的形状锁合促使第二轨道(5)与第一轨道(3)的附加的锁定。为了确保在碰撞情况下通过在任意的纵向位置中的附加锁定来锁定座椅轨道对的纵向位置,第一和第二锁定结构部(24、25;36、37)在各自的轨道对的两侧上均有布置并且在纵向方向(x)上彼此以规律的间距(a)布置,其中,在各自的轨道对的两侧上的第一锁定结构部(24a、25a;24b、25b)或者第二锁定结构部(36a、37b;36b、37b)在纵向方向(x)上彼此错开地布置。
