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 comprising a torsion bar;

a retractor brake comprising a linear actuator operatively connected to a braking mechanism; and

a retractor-deployed stay spooled by the torsion bar 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 linear actuator is a linear solenoid.

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

6. 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.

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

8. 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 comprising a torsion bar;

a retractor brake comprising a linear solenoid operatively connected to a braking mechanism; and

a retractor-deployed stay spooled by the torsion bar for selectively restraining opening of a vehicle door.

9. The system of claim 8, 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.

10. The system of claim 8, wherein the retractor is associated with one of a vehicle body or the vehicle door.

11. The system of claim 8, wherein the retractor brake is manually actuated.

12. The system of claim 8, 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.

13. The system of claim 8, wherein the door check is a door check arm or strap defining one or more detents engaged by one or more biased rollers.

14. A vehicle including the system of claim 8.
