Adaptive seat belt system
First Claim
1. A safety restraint system for a vehicle, the safety restraint system comprising:
- a seat belt webbing for restraining an occupant of the vehicle;
a seat belt retractor mounted to a first structural member of the vehicle for securing the seat belt to the vehicle and allowing protraction and retraction of the seat belt, the retractor having at least two load limiting modes;
a deflector for receiving the seat belt webbing and directing the seat belt webbing across the shoulder of the occupant;
a height adjuster for securing the deflector to a second structural member of the vehicle, wherein the deflector is positionable between at least two locations along the height adjuster including a first deflector location associated with a relatively smaller size occupant and a second deflector location associated with a relatively larger size occupant;
a latch plate deflector for receiving the seat belt webbing and redirecting the seat belt webbing across the lap of the occupant;
a buckle for receiving and removably securing the latch plate deflector when the seat belt is in use by the occupant; and
a communication link attached at a first end adjacent the height adjuster and at a second end to the retractor for switching the retractor to a low load limiting mode when the height adjuster is positioned to the first deflector location and to a high load limiting mode when the height adjuster is positioned to the second deflector location.

Abstract
A safety restraint system for a vehicle is disclosed. The safety restraint system has a seat belt webbing for restraining an occupant of the vehicle, a seat belt retractor, a deflector, a height adjuster, a latch plate deflector, a buckle and a communication link. The seat belt retractor mounted to a first structural member of the vehicle for securing the seat belt to the vehicle and allowing protraction and retraction of the seat belt. The retractor has at least two load limiting modes. The deflector receives the seat belt webbing and directs the seat belt webbing across the shoulder of the occupant. The height adjuster secures the deflector to a second structural member of the vehicle. The deflector is positionable between at least two locations along the height adjuster. The latch plate deflector receives the seat belt webbing and redirects the seat belt webbing across the lap of the occupant. The buckle receives and removably secures the latch plate deflector when the seat belt is in use by the occupant. The communication link is attached at a first end adjacent the height adjuster and at a second end to the retractor for switching the retractor from at least one load limiting mode to another.

8. A method for adjusting a safety restraint system of a vehicle, the safety restraint system having a seat belt webbing for restraining an occupant of the vehicle, a seat belt retractor mounted to a first structural member of the vehicle for securing the seat belt to the vehicle and allowing protraction and retraction of the seat belt, the retractor having at least two load limiting modes including a low load limiting mode and a high load limiting mode, a deflector for receiving the seat belt webbing and directing the seat belt webbing across the shoulder of the occupant, a height adjuster for securing the deflector to a second structural member of the vehicle, a latch plate deflector for receiving the seat belt webbing and redirecting the seat belt webbing across the lap of the occupant and a buckle for receiving and removably securing the latch plate deflector when the seat belt is in use by the occupant, the method comprising:
-
monitoring the height adjuster, which secures the deflector to a second structural member of the vehicle, to determine the location of the deflector along the height adjuster, wherein the deflector is positionable between at least two locations along the height adjuster including a first deflector location associated with a relatively smaller size occupant and a second deflector location associated with a relatively larger size occupant; communicating the location of the deflector along the height adjuster using a communication link attached at a first end adjacent the height adjuster and at a second end to the retractor; and switching the retractor to the low load limiting mode when the height adjuster is positioned to the first deflector location and to a high load limiting mode when the height adjuster is positioned to the second deflector location.

9. A safety restraint system for a vehicle, the safety restraint system comprising:
-
a seat belt webbing for restraining an occupant of the vehicle; a seat belt retractor mounted to a first structural member of the vehicle for securing the seat belt to the vehicle and allowing protraction and retraction of the seat belt, the retractor having at least two load limiting modes; a deflector for receiving the seat belt webbing and directing the seat belt webbing across the shoulder of the occupant; a height adjuster for securing the deflector to a second structural member of the vehicle, wherein the deflector is positionable between at least two locations along the height adjuster including a first deflector location associated with a relatively smaller size occupant and a second deflector location associated with a relatively larger size occupant; a latch plate deflector for receiving the seat belt webbing and redirecting the seat belt webbing across the lap of the occupant; a buckle for receiving and removeably securing the latch plate deflector when the seat belt is in use by the occupant; and a means for communicating the location of the deflector along the height adjuster, wherein the means is attached at a first end adjacent the height adjuster and at a second end to the retractor for switching the retractor to a low load limiting mode when the height adjuster is positioned to the first deflector location and to a high load limiting mode when the height adjuster is positioned to the second deflector location. - View Dependent Claims (10, 11, 12)
