Method of establishing belt pullout in an occupant restraint system for vehicles and an occupant restraint system for vehicles
First Claim
Patent Images
1. A method of limiting an acceleration transmitted to an occupant by an occupant restraint system of a vehicle in case of an accident where the occupant restraint system comprises a safety belt that allows belt pullout, a blocking device for blocking the belt pullout and a release device for acting on the blocking device to enable a defined length of the belt to be pulled out, the method comprising in case of an accident the steps of:
- detecting the vehicle acceleration;
defining a length of the belt greater than zero that is allowed to be pulled out based on the detected vehicle acceleration; and
operating the release device and causing the release device to act on the blocking device for enabling the defined length of the belt to be pulled out;
wherein the defined length of the belt allowed to be pulled out is independent of the mass of the occupant.

5. An occupant restraint system for vehicles that provides, during an accident, forward displacement for an occupant within the occupant restraint system, comprising:
-
at least one safety belt allowing a belt pullout greater than zero, a blocking device for blocking the belt pullout, and a release device acting on the blocking device for definedly enabling the belt pullout greater than zero, characterised by an acceleration detection unit which, in case of an accident, detects the vehicle acceleration and which, in dependence on the detected vehicle acceleration, determines a defined length of the belt greater than zero that is allowed to be pulled out and acts on the release device for enabling the determined length of the belt to be pulled out; wherein the defined length of the belt allowed to be pulled out is independent of the mass of the occupant. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
