Abstract

A safety device for vehicles having first sensor arrangement for acquiring the vehicle impact and for outputting first sensor signals, a control device for outputting triggering signals dependent on the first sensor signals, and a restraint system that is triggered dependent on the first sensor signals, second sensor arrangement being provided for the acquisition of obstacles in the vicinity of the vehicle and for the outputting of second sensor signals, and third sensor arrangement being provided for the acquisition of environmental influences on the second sensor arrangement, the second sensor signals output by the second sensor arrangement being used in the control unit for the decision concerning the triggering of the restraint system, after an evaluation of the third sensor signals output by the third sensor arrangement.
