Seatbelt guide mechanism
A seat system includes a seat having a seatback and an arm supported by the seatback. The arm is extendable from a stowed position to an intermediate position and pivotable in a seat-forward direction from the intermediate position to a deployed position. A webbing guide is fixed to and movable with the arm. The webbing guide is at a top end of the seatback when the arm is at the stowed position and the webbing guide is spaced from the seatback in the seat-forward direction when the arm is at the deployed position. A retractor is supported by the seatback at the top end and a webbing extends from the retractor through the webbing guide.
1. A seat system, comprising:
a seat including a seatback;
an arm supported by the seatback and extendable from a stowed position to an intermediate position and pivotable in a seat-forward direction from the intermediate position to a deployed position;
a webbing guide fixed to and movable with the arm, the webbing guide being at a top end of the seatback when the arm is at the stowed position, and the webbing guide being spaced from the seatback in the seat-forward direction when the arm is at the deployed position;
a retractor supported by the seatback at the top end; and
a webbing extending from the retractor through the webbing guide.
2. The seat system of claim 1 , further comprising a linear actuator operatively coupled to the arm to move the arm between the stowed position and the intermediate position.
3. The seat system of claim 2 , further comprising a rotary actuator operatively coupled to the arm to move the arm between the intermediate position and the deployed position.
4. The seat system of claim 1 , further comprising a rotary actuator operatively coupled to the arm to move the arm between the intermediate position and the deployed position.
5. The seat system of claim 1 , further comprising a rack and pinion mechanism coupled to the arm and operative to move the arm between the stowed position and the intermediate position.
6. The seat system of claim 5 , wherein the rack and pinion mechanism comprises a pinion gear and a gear rack, the gear rack being pivotably coupled to the arm.
7. The seat system of claim 6 , further comprising an actuator positioned between the gear rack and the arm to move the arm between the intermediate position and the deployed position.
8. The seat system of claim 7 , wherein the actuator is a rotary actuator.
9. The seat system of claim 1 , further comprising a latch plate slidably disposed on the webbing.
10. The seat system of claim 1 , further comprising an elongate housing at least partially containing the arm when the arm is in the stowed position.
11. The seat system of claim 10 , wherein the housing is positioned inside the top end of the seatback.
12. The seat system of claim 11 , wherein the housing carries a linear actuator operatively coupled to the arm to extend the arm between the stowed position and the intermediate position.
13. The seat system of claim 1 , further comprising a linear actuator operatively coupled to the arm to extend the arm between the stowed position and the intermediate position and a rotary actuator operatively coupled between the linear actuator and the arm to pivot the arm between the intermediate position and the deployed position.
14. The seat system of claim 13 , further comprising a computer having a processor and a memory storing instructions executable by the processor to activate the linear actuator and the rotary actuator to move the webbing guide from the stowed position to the deployed position in response to determining that an occupant is seated in the seat.
15. The seat system of claim 14 , further comprising a seat bottom, a latch plate slidably disposed on the webbing, and a buckle attached to the seat bottom and operative to releasably engage the latch plate.
16. The seat system of claim 15 , wherein the memory stores instructions executable by the processor to, after moving the arm to the deployed position, activate the linear actuator and the rotary actuator to return the arm to the stowed position in response to determining that the latch plate is inserted into the buckle.
17. The seat system of claim 16 , further comprising an occupancy sensor.
18. The seat system of claim 14 , further comprising an elongate housing at least partially containing the arm when the arm is in the stowed position.
19. The seat system of claim 18 , wherein the housing is positioned inside the top end of the seatback.
20. The seat system of claim 19 , wherein the housing carries the linear actuator.
