Abstract:
1. A sun roof system for selectively opening an opening of a vehicle roof with a sun roof panel, comprising: a pair of guide rails extending along either lateral side of the opening of the vehicle roof; a pair of panel brackets integrally attached to either lateral side of the sun roof panel, each panel bracket including a front cam piece provided at a front part thereof, a rear cam piece provided at some distance behind the front cam piece and a guide slot extending a prescribed distance in a fore-and-aft direction and given with a prescribed profile; a front slider provided at a front end of each panel bracket for slidably supporting a front end of the panel bracket on the corresponding guide rail; a rear slider provided slidably supported by each guide rail behind the corresponding front slider, the rear slider being provided with a pin that engages the guide slot; and an actuator for actuating each rear slider in the fore-and-aft direction; the profile of the guide slot being configured such that a forward movement of the pin along the guide slot from a neutral point causes a vertical upward tilting of the sun roof panel around the front slider, a rearward movement along the guide slot from the neutral point causes a vertical downward tilting of the sun roof panel around the front slider as the pin travels, and a further rearward movement of the pin along the guide slot causes a rearward sliding movement of the sun roof panel; wherein the guide rail is provided with a front main cam groove and a rear main cam groove for guiding the front cam piece and rear cam piece in the fore-and-aft direction, a front vertical cam groove for vertically guiding the front cam piece into and out of the front main cam groove and a rear vertical cam groove for vertically guiding the rear cam piece into and out of the rear main cam groove, and wherein the sun roof panel is at a first angle (d
