[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a panel holding structure for a sunroof for vehicles such as passenger cars.

[0002]

[Prior Art]

 The sunroof used in passenger cars has an opening formed in the vehicle roof, and guide rails in the front-rear direction that are fixed to the roof are placed on the left and right of this opening, and the lower surface of the glass panel that opens and closes the opening. A mounting frame is provided on the outer circumference, and the inner parts of the pair of left and right front guides are attached to the front lower part of the inner peripheral part of this mounting frame, and the support parts are installed on the outer parts protruding from the inner part of each front guide to the left and right sides of the panel. The support portion is engaged with the guide rail so as to be slidable back and forth, and is configured so that the drive mechanism moves the panel forward and backward with respect to the guide rail and tilts the front portion. ..

[0003]

[Problems to be solved by the device]

 In the vehicle sunroof, each front guide has a long distance from the panel mounting portion of the inner portion to the support portion of the outer portion, and therefore the distance from the center of the panel to the support portion is long, and the front guide is Since it is supported only by the support part and is easily tilted, it is difficult to strongly support the resistance applied to the panel.

Therefore, when the panel is tilted in the front position from the tilt-up posture or the tilt-down posture to the closed posture, the seal attached to the outer periphery of the panel is brought into sliding contact with the roof, so that resistance in the direction opposite to the tilt movement direction is generated. I will receive it. Due to this resistance, each front guide may be bent or tilted by receiving a bending moment, and the front part of the panel, especially the center part in the left-right direction, may be largely bent up and down to become higher than the roof surface. It may become low or have a step with the roof.

This problem can be solved to some extent by enlarging the shape or plate thickness of the front guide to increase the section modulus and increasing the bending rigidity of the front guide itself, but increasing the shape or plate thickness of the front guide. However, it is difficult to use in practice because of the size limitation of the arrangement. In the present invention, the left and right front guides are provided with a holding portion located closer to the panel mounting portion than the supporting portion, and a roof side is provided with a vertical position regulating portion that engages with the holding portion and regulates vertical movement. At the time of position, the holding part and the vertical position restricting part are engaged to support the left and right front guides at two points to shorten the distance from the center of the panel to the supporting part and prevent the front guide from tilting. Thus, it is an object of the present invention to provide a panel holding structure for a vehicle sunroof capable of solving the above-mentioned problems.

[0006]

[Means for Solving the Problems]

 The concrete means for solving the problem in the present invention is to arrange guide rails 3 fixed to the roof 1 on the left and right sides of the opening 2 of the roof 1 and to the left and right on the lower front part of the panel 4 for opening and closing the opening 2. The inner portions of the pair of front guides 5 are attached, and the support portions 6 formed on the outer portions projecting from the inner portions of the front guides 5 to the left and right sides of the panel are engaged with the guide rails 3 so as to be slidable back and forth. In a vehicle sunroof provided with a drive mechanism 7 for moving the guide rail 4 back and forth with respect to the guide rail 3 and tilting the guide rail 3 at the front position, the front and rear positions of the left and right front guides 5 substantially correspond to the support portion 6 and A holding portion 8 whose position is located inside the support portion 6 is provided, and an up-and-down position regulating portion 9 that engages with the holding portion 8 and regulates vertical movement when the panel 4 is at the front position on the roof 1 side. Is provided It is when.

[0007]

[Action]

 When the panel 4 is at the front position, the left and right front guides 5 are engaged with the guide rails 3 at the same time, and at the same time, the holding portion 8 located inside the support portion 6 is moved up and down. , And each front guide 5 is supported at two places on the left and right sides so as to prevent vertical movement.

When the panel 4 is tilted from the tilt-up posture B or the tilt-down posture C to the closed posture A via the drive mechanism 7, the front part of the panel 4 receives downward or upward resistance from the roof 1. , The distance from the front center to the supporting part is shortened, and since the front guide 5 is not tilted in the left-right direction, the bending moment generated in the front guide 5 is small, and the panel 4 hardly bends. Tilt motion.
