Adjustable passenger restraint system support for a vehicle

A vehicle defining a front-rear axis and a vertical axis and comprising:

• a body including a passenger compartment;
• a vehicle seat system arranged in the passenger compartment, the vehicle seat system comprising:
• a seat including a seat base and a seat back having a first end pivotally connected to the seat base and a second end;
• and
• a belt guide system mounted adjacent to the second end of the seat base, the belt guide system including:
• a guide mechanism supportable in a vehicle, the guide mechanism including a guide track having a first end section, a second end section, and an intermediate section extending between the first end and the second end;
• a shuttle arranged at the guide track, the shuttle being shiftable between the first end section and the second end section;
• an actuator operatively connected to the shuttle, the actuator being operable to shift the shuttle between the first end section and the second end section;
• a belt guide mounted to the shuttle;
• a seat back position sensor coupled to the seat back, the seat back position sensor detecting an angular displacement of the seat back from the vertical axis;
• and
• a controller operatively connected to the actuator and the seat back position sensor, the actuator shifting the shuttle between the first end section and the second end section in response to angular displacement of the seat back detected by the seat back position sensor,
• wherein the guide track guides the shuttle in a direction that has a larger component along the front-rear axis than in the vertical axis.

A method of adjusting a seatbelt belt guide in a vehicle that defines a forward direction, the method comprising:

• detecting an angular displacement of a seatback from the vertical axis, the seatback moving from a first position to a second position;
• and
• shifting the seatbelt belt guide from a first anchor location corresponding to the first position of the seatback to a second anchor position corresponding to the second position of the seatback in response to the angular displacement of the seatback via a belt guide system comprising a guide mechanism including a guide track having a first end section correspond to the first anchor location and a second end section corresponding to the second anchor location and a shuttle arranged at the guide track shiftable between the first end section and the second end section,
• wherein the guide track guides the shuttle in a direction that has a larger component along the front-rear axis than in the vertical axis.
