Patent Images
1. A vehicle occupant safety system, comprising:
- at least one restraint device (12, 14) having at least one adjustable parameter,a vehicle seat (16) having at least one seat sensor (20a-g) detecting the sitting position of a vehicle occupant (42), and a weight shift on the part of the vehicle occupant (42),a seatbelt system (22) having at least one belt extension sensor (30) detecting the belt extension length (LG), anda control unit (34) determining from the values of the sitting position and weight shift of the vehicle occupant from the seat sensor (20a-g) and a change in the belt extension length (LG) from the belt extension sensor (30) whether a vehicle occupant (42) is in a forward-leaning position,the control unit (34) specifying the value of the adjustable parameter of the restraint device (12, 14) as a function of a forward-leaning position of the vehicle occupant (42).

Abstract
A vehicle occupant safety system has at least one restraint device having at least one adjustable parameter, a vehicle seat having at least one seat sensor detecting the sitting position of a vehicle occupant, a seatbelt system having at least one belt extension sensor detecting the belt extension length, and a control unit determining from the values from the seat sensor and from the belt extension sensor whether a vehicle occupant is in a forward-leaning position. The control unit then specifies the value of the adjustable parameter of the restraint device as a function of a forward-leaning position of the vehicle occupant.
