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.

First claim

What is claimed:

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 .
