Automotive sun roof device

Abstract

A sun roof device of a motor vehicle comprises a lid member sized to cover a sun roof opening and having a weather strip disposed therearound. The lid member is capable of assuming a full close position wherein the weather strip on a front end of the lid member is pressed against a front edge of the sun roof opening. A guide rail extends along each side portion of the sun roof opening. A bracket is secured to each side portion of the lid member. A front slide member is slidably engaged with the guide rail. A pivot pin is provided through which the front slide member and a front portion of the bracket are pivotally connected. A rear slide member is slidably engaged with the guide rail and formed with first and second cam grooves. A drive arm has an upper end pivotally connected to a rear portion of the bracket. Lower and center cam followers are connected to the drive arm, which are slidably engaged with the first and second cam grooves respectively, so that when the rear slide member is moved forward from a given position, the lid member is tilted up from the full close position lifting a rear end thereof from a rear edge of the sun roof opening and when the rear slide member is moved rearward from the given position, the lid member is tilted down from the full close position lowering the rear end thereof from the rear edge of the sun roof opening. A cam groove member is further employed which is connected to the guide rail. The cam groove member has a cam groove with which the lower cam follower is slidably engaged for enforcedly separating the weather strip on the front end of the lid member from the front edge of the sun roof opening when the lid member is shifted from the full close position to the tilt-up position.
