Title: Slide roof for vehicle
Inventor: RITTER BERNHARD
IPC: B60J7/057
Filed: 2000-02-09
Abstract: PROBLEM TO BE SOLVED: To precisely reproduce the close position by necessarily moving a cover to a close position from only one selected moving direction. SOLUTION: A slide roof 1 is driven by an external force for example, and a cover 4 is moved in a first moving direction from a close position S and set to an open position O, or the cover 4 is moved in a second moving direction and set to a lifted position H. At this time, the cover 4 is necessarily laid in the close position S from only one selected moving direction. According to this, the looseness of a transmission mechanism or the influence of elasticity of the drive part of the slide roof is suppressed, so that the cover is set in the same position at every closing process. According to this, the appearance of a vehicle can be improved, and when the cover is moved to the close position to close the slide roof, the noise by the wind caused by the clearance around the cover can be regulated to be minimized.  Further, when the cover is closed from the non-selected moving direction, the close position S is thereafter started from the selected direction by operation.
