The invention relates to a seat rail module for a vehicle seat, comprising two longitudinal adjustment rails (10) arranged parallel to one another for the guidance and longitudinal adjustment of the vehicle seat (1), deformation units (18) that can be fastened, or are fastened, to the longitudinal adjustment rails (10), and fastening elements (25) for fastening the seat rail module at the bottom of a vehicle chassis. The vehicle seat (1) can be fastened to the longitudinal adjustment rails (10), and the deformation units (18) are designed to deform deformation elements (19) in a main directionof travel if the vehicle seat is displaced so as to decelerate the vehicle seat in the event of a crash. The invention is characterized in that the fastening elements (25) are designed to fasten theseat rail module at the bottom of a vehicle chassis by means of locking, and that during a longitudinal adjustment of the vehicle seat (1), the fastening elements (25) are mechanically unlocked in theopposite direction to the main direction of travel beyond a predetermined boundary line (8). In the rear area, in which the vehicle seat assumes a relatively far backward displaced seating position,as is made possible, for example, in the future for "autonomous driving" or as a relaxation position, measures for protecting the occupants are also provided to a sufficient extent, even if in this area, occupant protection systems, in particular front airbags, are no longer effective.
一种用于车辆座椅的座椅导轨模块,包括:两个纵向调节导轨(10),彼此平行布置以用于引导车辆座椅(1)并在纵向方向上调整其位置;变形单元(18),其能够被紧固或被紧固到所述纵向调节导轨(10);以及紧固构件(25),用于将所述座椅导轨模块紧固到车辆本体的底板,其中,所述车辆座椅(1)能够被紧固到所述纵向调节导轨(10),且所述变形单元(18)被配置成当所述车辆座椅在主行进方向上移位时使变形构件(19)变形,以便在碰撞情况下使所述车辆座椅减速,其特征在于所述紧固构件(25)被配置成借助锁定将所述座椅导轨模块紧固到所述车辆本体的底板,且在所述车辆座椅(1)在与所述主行进方向相反的方向上纵向移位超过预定限制线(8)时,机械解锁所述紧固构件(25)。并且,在其中所述车辆座椅采取相对向后移位很远的座椅位置(例如未来可能用于“自主驾驶”或作为放松位置的座椅位置)的后部区域中,即使前排乘员保护系统(尤其是前排安全气囊)在此区域中不再有效也会在足够的程度上提供用于乘员保护的预防措施。
