Claim 0:
1. A seat rail module for use in a vehicle seat, the seat rail module comprising:
two longitudinal adjustment rails configured to be arranged parallel to each other, wherein each of the longitudinal adjustment rails include an upper rail and lower rail, the upper rails are fastened to the vehicle seat, the two longitudinal adjustment rails configured to guide the vehicle seat as a position of the vehicle seat is adjusted in a longitudinal direction,
deformation units configured to be fastened to the longitudinal adjustment rails, and
fastening members configured to fasten the lower rails to a floor of a vehicle body, wherein
the deformation units include deformation members, the deformation members configured to deform in response to displacement of the vehicle seat in a main direction of travel to decelerate the vehicle seat in the event of a crash, wherein
in a normal state, the fastening members are configured to lock the seat rail module to the floor of the vehicle body, and
the fastening members are configured to be mechanically unlocked upon in response to:
a displacement of the vehicle seat in the longitudinal direction, and
a displacement of the vehicle seat, in a direction opposite to the main direction of travel, beyond a predetermined limit line to a region in which one or more front occupant protection systems are ineffective and do not protect an occupant disposed in the vehicle seat.
