Abstract

A vehicle sunroof apparatus includes check mechanisms each including a rotary cam and a fixed cam. The fixed cam includes a switch guide which switches the check mechanism between an engaged state and a disengaged state. The switch guide allows advancement of the rotary cam which is at an advancement and retraction rotary position, pushes the rotary cam to a first rotary position, and further pushes the rotary cam to a second rotary position, the check mechanism is thereby switched to the engaged state. The switch guide pushes the rotary cam to a release preparation position, further pushes the rotary cam to the advancement and retraction rotary position, the check mechanism is thereby switched to the disengaged state. The fixed cam includes an initialization guide that pushes the rotary cam to the release preparation position.

First claim

The invention claimed is:

1. A sunroof apparatus for a vehicle, the sunroof apparatus comprising:
a movable panel opening and closing an opening formed at a roof of a vehicle;
guide rails provided as a pair and respectively provided at edge portions of the opening in a width direction of the vehicle;
sliding members provided as a pair and respectively linked to edge portions of the movable panel in the width direction of the vehicle, the sliding members driven by an electric drive source to move along the guide rails in a front-and-rear direction of the vehicle, the sliding members changing a posture of the movable panel by moving relative to the movable panel and maintaining the posture of the movable panel by moving integrally with the movable panel;
check mechanisms each including a rotary cam and a fixed cam, the rotary cams being supported at one of the respective sliding members and the respective edge portions of the movable panel, the fixed cams being supported at the other of the respective sliding members and the respective edge portions of the movable panel;
each of the rotary cams being supported to be rotatable about an axis line extending in the front-and-rear direction of the vehicle and including an advancement and retraction rotary position set at a predetermined angle about the axis line;
each of the fixed cams including an engagement and disengagement switch guide configured to switch each of the check mechanisms between an engaged state in which the movable panel and the sliding members are movable integrally with each other and a disengaged state in which the sliding members are movable relative to the movable panel;
the engagement and disengagement switch guides being configured to allow advancement of the respective rotary cams which are at an advancement and retraction rotary position, the engagement and disengagement switch guides being configured to push the rotary cams which have advanced and to rotate the rotary cams to a first rotary position, the engagement and disengagement switch guides being configured to push the rotary cams which are to retract in a direction opposite to a direction of the advancement and to rotate the rotary cams to a second rotary position, each of the check mechanisms thereby being switched to the engaged state when the corresponding rotary cam rotates by a half angle of the predetermined angle from the advancement and retraction rotary position to the second rotary position;
the engagement and disengagement switch guides being configured to push the respective rotary cams advancing again from the second rotary position in a direction opposite to a direction of the retraction and to rotate the rotary cams to a release preparation position, the engagement and disengagement switch guides being configured to push the rotary cams which are to retract in the direction opposite to the direction of advancement and to rotate the rotary cams to the advancement and retraction rotary position, each of the check mechanisms thereby being switched to the disengaged state; and
each of the fixed cams further including an initialization guide configured to push the rotary cam advancing further from the first rotary position and to rotate the rotary cam to the release preparation position.

2. The sunroof apparatus for a vehicle according to claim 1 , wherein
each of the fixed cam includes a second initialization guide arranged between the engagement and disengagement switch guide and the initialization guide in the front-and-rear direction of the vehicle, and
in a case where each of the rotary cams guided by the initialization guide retracts in the direction opposite to the direction of the advancement in a state where the rotary cam has not reached the release preparation position, the second initialization guide is configured to push the rotary cam and to rotate the rotary cam to the release preparation position.

3. The sunroof apparatus for a vehicle according to claim 1 , wherein
each of the fixed cams includes a through hole, and
in association with a further advancement of the rotary cams which have been rotated by the initialization guides to the release preparation position, the through holes allow at least part of the rotary cams to pass through.
