A vehicle seat comprising a seat member and a backrest, wherein a belt connection is attached to or integrated into the upper end of the backrest, a mechanical coupling device is provided for coupling the backrest to the assembly for adjustment of the inclination of the seat member in the event of a collision. A triggering threshold is defined wherein the backrest is decoupled from the assembly under normal operating conditions, and wherein in a collision, when the triggering threshold is exceeded, the backrest pivots forwards and is finally coupled via the mechanical coupling device to the assembly, so that further pivoting of the backrest forwards triggers the assembly and causes the front region of the seat member facing away from the backrest to pivot upwards about a transverse axis.
