The invention relates to a safety arrangement for a vehicle, in particular for a motor vehicle with an airbag (2), folded together in the non-activated basic state, which on a triggering of the safety arrangement (1) by an activation signal is able to be inflated with different volumes in the direction of the interior of the vehicle by means of a gas generator (3), and with a crash sensor system which detects a vehicle impact and emits the activation signal for this. According to the invention, the crash sensor system comprises both a pre-crash sensor system and also an in-crash sensor system, wherein the pre-crash sensor system generally already detects an impending collision before an actual impact, and for this circumstance emits a pre-crash activation signal as activation signal. The in-crash sensor system detects an actual impact and for this circumstance emits an in-crash activation signal (backup) if the pre-crash sensor system has previously not detected the impending collision and has not emitted a pre-crash activation signal. The airbag is able to be inflated to a larger airbag volume (FIG. 1; Volume A+B) and to a relatively smaller airbag volume (FIG. 2; Volume A) by comparison, wherein by a pre-crash activation signal in a pre-crash mode the inflation process is activated for the larger airbag volume (FIG. 1; Volume A+B), and by an in-crash activation signal in an in-crash mode the inflation process is activated for the relatively smaller airbag volume (FIG. 2; Volume A).
