Claims16
A computer-implemented method for moving an occupant of a vehicle seat to open airway position after a vehicle crash event, the vehicle seat having a seat cushion, a backrest and a headrest, the method comprising:
- detecting occurrence of a vehicle crash event, and
- moving at least a portion of the backrest and/or headrest backwards and pulling an occupant of the vehicle seat backwards towards the backrest by powered retraction of a seat belt of the occupant by means of a seat belt retractor.
A vehicle seat system for moving an occupant of a vehicle seat to an open airway position after a vehicle crash event, the vehicle seat system comprising:
- a seat having a seat cushion, a backrest and a headrest, wherein the seat further has one or more power actuators configured for adjusting a motion position of the backrest and/or headrest,
- a seat belt arrangement having a seat belt and a seat belt retractor, wherein the seat belt arrangement further has power source drivingly connected to the seat belt retractor for enabling powered retraction, and
- an electronic control system operatively connected to the one or more power actuators of the seat and power source of the seat belt arrangement,
- wherein the control system is configured for:
- determining occurrence of a vehicle crash event, and
- controlling operation of the one or more power actuators of the seat for moving at least a portion of the backrest and/or headrest backwards, and controlling operation of the power source of the seat belt retractor for pulling the occupant of the vehicle seat backwards towards the backrest.
