Abstract
Seat centric airbag restraint systems having pelvis restraint features, along with related methods. In some implementations, a first seat-mounted airbag cushion may be deployed along a first side of a vehicle occupant and a second seat-mounted airbag cushion may be deployed along a second side of the vehicle occupant. A first pelvis restraint chamber may be deployed below the first seat-mounted airbag cushion at an angle relative to the first seat-mounted airbag cushion and towards a first upper thigh of the vehicle occupant. The first pelvis restraint chamber may inhibit forward translation of the vehicle occupant within a vehicle seat by tensioning the pelvis region of the occupant.
Claims20
A method for restraining forward translation of a vehicle occupant during an impact event, the method comprising the steps of:
- deploying a first seat-mounted airbag cushion along a first side of a vehicle occupant;
- deploying a second seat-mounted airbag cushion along a second side of the vehicle occupant;
- and
- deploying a first pelvis restraint chamber below the first seat-mounted airbag cushion at an angle relative to the first seat-mounted airbag cushion towards a centerline of a seat in which the vehicle occupant is sitting and towards a first upper thigh of the vehicle occupant in front of the vehicle occupant, wherein the first pelvis restraint chamber contacts the first seat-mounted airbag cushion and inhibits forward translation of the vehicle occupant within a vehicle seat.
