Method for the restraint of a vehicle occupant

A method for the restraint of a vehicle occupant with the aid of a vehicle restraint system which comprises a windable three-point safety belt, comprising the steps of:

• permitting forward displacement of the vehicle occupant in the event of an accident;
• controlling a direct slackening of the safety belt in dependence on the permitted forward displacement such that the reaction force (belt force) transmitted to the vehicle occupant does not exceed a pre-set maximum value;
• and
• measuring the forward displacement of the vehicle occupant in dependence on time, and wherein the step of controlling the direct slackening of the safety belt includes controlling the slackening of the safety belt n dependence on the measured forward displacement and characteristic vehicle values.

• controlling a direct slackening of the safety belt in dependence on the permitted forward displacement such that the reaction force (belt force) transmitted to the vehicle occupant does not exceed a pre-set maximum value;
• and
• recalling the permitted forward displacement of the vehicle occupant from a storage in memory and wherein the slackening of the safety belt is controlled in dependence on the stored forward displacement as well as in dependence on characteristic vehicle values and characteristic occupant values.

• permitting forward displacement of the vehicle occupant in the event of an accident;
• controlling a direct slackening of the safety belt in dependence on the permitted forward displacement such that the reaction force (belt force) transmitted to the vehicle occupant does not exceed a pre-set maximum value;
• storing pre-set maximum values of motor vehicle characteristics and/or occupant values in a characteristic field in a memory of a control;
• reading the stored maximum values out of memory in the event of an accident, stored maximum values are read out of the memory;
• and
• wherein the slackening of the safety belt takes place in dependence on the maximum values read such that the belt force falls short of the maximum value.

A method for the restraint of a vehicle occupant with the aid of a vehicle restraint system which comprises a windable three-point safety belt, comprising the steps of:

• permitting forward displacement of the vehicle occupant in the event of an accident;
• controlling a direct slackening of the safety belt in dependence on the permitted forward displacement such that the reaction force (belt force) transmitted to the vehicle occupant does not exceed a pre-set maximum value;
• and
• wherein the direct slackening of the safety belt is controlled such that the pre-set maximum value of the belt force is achieved as early as possible—relative to the time of the impact of the accident—and is maintained for the time of the impact of the accident.
