METHOD FOR CONTROLLING A TIME OF ACTIVATION OF A REVERSIBLE RESTRAINT SYSTEM IN A VEHICLE
First Claim
Patent Images
1. A method for controlling a time of activation of a restraint system in a vehicle, the vehicle including a seat belt associated with a seat and the restraint system, the restraint system being a reversible restraint system, the method comprising:
- a) determining a current length of pulled out seat belt;
b) detecting a collision or an imminent collision involving the vehicle;
c) predicting a time when the collision or imminent collision will affect a user of the seat belt; and
d) activating the reversible restraint system a selectable time period before the time when the collision or imminent collision is predicted to affect the user of the seat belt, wherein a length of the selectable time period is a function of the determined current length of pulled out seat belt.

Abstract
The present disclosure relates to a method for controlling a time of activation of a restraint system in a vehicle, the vehicle comprising a seat belt associated to a seat, the restraint system being a reversible restraint system, the method comprising the steps of
- a) determining a current length (L) of pulled out seat belt,
- b) detecting a collision or an imminent collision involving the vehicle,
- c) predicting a time (T0) when the collision is predicted to affect a user of the seat belt,
- d) activating the reversible restraint system a selectable time period (Δ1) before the time (T0) when the collision is predicted to affect the user of the seat belt, wherein a length of the selectable time period (Δ1) is a function of the determined current length (L) of pulled out seat belt. The disclosure further relates to a safety arrangement of a vehicle.

9. A safety arrangement for a vehicle, the safety arrangement comprising:
-
a seat belt; a first sensor for directly or indirectly determining a current length of pulled out seat belt; a system for detecting a collision or an imminent collision involving the vehicle; a reversible restraint system; and a processor adapted for predicting a time when the collision or imminent collision will affect a user of the seat belt, and for activating the reversible restraint system a selectable time period before the time, wherein a length of the selectable time period is a function of the determined current length of pulled out seat belt. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
