1. A vehicle seat having a base and a displaceable seat member which when a backrest of the vehicle seat is tilted forward can be lowered at least with a front portion in the direction of the base, wherein there is provided a guiding element which when the front portion of the seat member is lowered can be displaced on a slotted guiding member for the guiding element from a first portion of the slotted guiding member to a second portion of the slotted guiding member, wherein
the slotted guiding member or the guiding element is provided on a blocking element of a blocking device of the vehicle seat, and
the blocking element with the slotted guiding member or with the guiding element can be displaced under the action of acceleration forces which occur in the event of a crash relative to the base in such a manner that the guiding element in the event of a crash from the first portion of the slotted guiding member moves into abutment with a third portion of the slotted guiding member which is different from the first and second portions in a blocking position in which a lowering of the front portion of the seat member is blocked.
