Abstract

An apparatus and method for a sunroof of a vehicle, including a movable panel, a rail, a drive shoe, a pivot link to control tilting of the movable panel as the drive shoe slides in the forward direction, a lift guide facilitating sliding of the movable panel, and a check assembly for engaging and disengaging the lift guide and the drive shoe. The check assembly includes a mechanical lock, a locking pin, a rotatable lock rotatable about the locking pin and configured with a locked position to prevent movement of the lift guide when the check assembly is disengaged, and a lock guide to guide the rotatable lock into the locked or an unlocked position. The rotatable lock includes a notch to catch an end portion of the mechanical lock and prevent the rotatable lock from rotating into the unlocked position when the check assembly is disengaged.

First claim

What is claimed is:

1. A tilt and slide apparatus for a sunroof of a vehicle, comprising:
a movable panel configured to open and close an opening formed at a roof of the vehicle;
a rail provided at each edge portion in the opening in a vehicle width direction and being extended in a forward-rearward direction of the vehicle;
a drive shoe configured to slide in each of a forward and a rearward direction of the vehicle;
a pivot link pivotally coupled to the drive shoe, the pivot link configured to control tilting of the movable panel as the drive shoe slides in the forward direction;
a lift guide connected to an end of the movable panel for facilitating sliding of the movable panel in the rearward direction; and
a check assembly for engaging and disengaging the lift guide and the drive shoe, the check assembly including
a locking pin mounted to and extending from the lift guide;
a mechanical lock slidably mounted to the lift guide via the locking pin, the mechanical lock including an end portion;
a rotatable lock mounted to and rotatable about the locking pin, the rotatable lock including a notch configured to engage the end portion of the mechanical lock and when the end portion engages the notch, the rotatable lock is prevented from rotating about the locking pin.

2. The tilt and slide apparatus of claim 1 , wherein the rotatable lock further includes a protrusion extended from an outer periphery of the rotatable lock and configured to engage a lock guide in the locked position.

3. The tilt and slide apparatus of claim 2 , wherein when the protrusion is facing downward direction, the notch is oriented so that the end portion of the mechanical lock enters the notch as the drive shoe moves in the forward direction.

4. The tilt and slide apparatus of claim 1 , wherein the check assembly further includes a locking component, and
wherein the check assembly is configured to align a portion of the locking component in order to couple the drive shoe and the lift guide.

5. The tilt and slide apparatus of claim 4 , wherein the check assembly further includes a receptacle mounted to the drive shoe, and
wherein the check assembly is configured to urge the locking component into alignment with the receptacle.

6. The tilt and slide apparatus of claim 5 , wherein the check assembly is configured to urge the locking component by rotating the locking component as it approaches and enters a front of the receptacle into an orientation in which the locking component is properly aligned with the receptacle.

7. The tilt and slide apparatus of claim 1 , wherein the check assembly is configured to maintain the drive shoe and the lift guide in a coupled state while the pivot link is locked in the raised position in order to facilitate sliding of the movable panel in the rearward direction opposite the forward direction.

8. The tilt and slide apparatus of claim 1 , wherein the check assembly is configured to decouple the drive shoe from the lift guide.

9. A method for a tilt and slide apparatus for a sunroof of a vehicle, the tilt and slide apparatus including a movable panel configured to open and close an opening formed at a roof of the vehicle, a rail provided at each edge portion in the opening in a vehicle width direction and being extended in a forward-rearward direction of the vehicle, a drive shoe configured to slide in each of a forward and a rearward direction of the vehicle, a pivot link pivotally coupled to the drive shoe, the pivot link configured to control tilting of the movable panel, a lift guide connected to an end of the movable panel for facilitating sliding of the movable panel, and a check assembly for engaging and disengaging the lift guide and the drive shoe, the check assembly including a locking pin mounted to and extending from the lift guide, a mechanical lock slidably mounted to the lift guide via the locking pin, the mechanical lock including an end portion, and a rotatable lock mounted to and rotatable about the locking pin, the rotatable lock including a notch configured to engage the end portion of the mechanical lock, the method comprising:
while the check assembly is disengaged, engaging by the end portion of the mechanical lock the notch in the rotatable lock to prevent the rotatable lock from rotating;
when the drive shoe moves in the forward direction to the lift guide, pivoting the pivot link to a raised position to tilt the movable panel;
coupling the drive shoe and the lift guide via the check assembly;
locking the pivot link in the raised position;
cooperatively moving the drive shoe and the mechanical lock in the rearward direction away from the lift guide;
while the mechanical lock is separating from the lift guide to provide a gap between an end of the lift guide and end surface of the mechanical lock, the end portion of the mechanical lock moves out of the notch.

10. The method of claim 9 , wherein the rotatable lock further includes a protrusion extended from an outer periphery of the rotatable lock, the method further comprising:
when the mechanical lock is engaged with the notch, the protrusion is in a vertical orientation facing a downward direction.

11. The method of claim 10 , further comprising:
when the protrusion is in the vertical orientation and the end portion of the mechanical lock enters the notch the rotatable lock is prevented from rotating.

12. The method of claim 9 , wherein the check assembly further includes a receptacle mounted to the drive shoe,
wherein the coupling by the check assembly includes aligning a portion of a locking component in order to couple the drive shoe and the lift guide by urging the locking component into alignment with the receptacle.

13. The method of claim 12 , further comprising:
urging by the check assembly the locking component by rotating the locking component as it approaches and enters a front of the receptacle into an orientation in which the locking component is aligned with the receptacle.

14. The method of claim 9 , further comprising:
maintaining the drive shoe and the lift guide in a coupled state while the pivot link is locked in the raised position while sliding the movable panel in the rearward direction.

15. The method of claim 9 , further comprising:
decoupling the drive shoe from the lift guide.
