Abstract

A door restraint system includes a retractor, a retractor brake, and a retractor-deployed stay for selectively restraining opening of a vehicle door. The retractor-deployed stay is configured to spool to and from the retractor as vehicle door is translated between a closed configuration and one or more opened configurations. Door check systems including the door restraint system are described.

Claims

1. A door restraint system for a vehicle, comprising:

a retractor;

a retractor brake; and

a retractor-deployed stay for selectively restraining opening of a vehicle door.

2. The system of claim 1, wherein the retractor-deployed stay spools to and from the retractor as the vehicle door is translated between a closed configuration and one or more opened configurations.

3. The system of claim 1, wherein the retractor is associated with one of a vehicle body or the vehicle door.

4. The system of claim 1, wherein the retractor comprises a torsion bar for spooling the retractor-deployed stay.

5. The system of claim 4, wherein the retractor brake comprises a linear actuator operatively connected to a braking mechanism.

6. The system of claim 5, wherein the linear actuator is a linear solenoid.

7. The system of claim 1, wherein the retractor brake is manually actuated.

8. The system of claim 1, wherein the retractor brake is operatively connected to a controller which in turn is configured to receive an input from a vehicle door-mounted proximity sensor.

9. A motor vehicle including the system of claim 1.

10. A door check system for a vehicle, comprising:

a door check mechanism providing one or more pre-determined vehicle door open positions; and

a door restraint system, comprising;

a retractor;

a retractor brake; and

a retractor-deployed stay for selectively restraining opening of a vehicle door.

11. The system of claim 10, wherein the retractor-deployed stay spools to and from the retractor as the vehicle door is translated between a closed configuration and one or more opened configurations.

12. The system of claim 10, wherein the retractor is associated with one of a vehicle body or the vehicle door.

13. The system of claim 10, wherein the retractor comprises a torsion bar for spooling the retractor-deployed stay.

14. The system of claim 13, wherein the retractor brake comprises a linear actuator operatively connected to a braking mechanism.

15. The system of claim 14, wherein the linear actuator is a linear solenoid.

16. The system of claim 10, wherein the retractor brake is manually actuated.

17. The system of claim 10, wherein the retractor brake is operatively connected to a controller which in turn is configured to receive an input from a vehicle door-mounted proximity sensor.

18. The system of claim 10, wherein the door check is a door check arm or strap defining one or more detents engaged by one or more biased rollers.

19. A vehicle including the system of claim 10.
