Abstract
Abstract A guiding mechanism for slidable curved window panes of automotive vehicles, comprising a curved, relatively elongated guide rail having one end pivotally fixed in the upper portion of the vehicle door body and the other end adjustably positioned in the lower portion of the vehicle door body, at least two sliding rollers mounted on the window pane and slidably engaged with the guide rail, and adjusting means for adjusting the lower portion of the guide rail with respect to the door inner panel. The guide rail is positioned in the vehicle door body in spaced substantially parallel relationship with respect to an arcuate path crossing uppermost and lowermost points between which the window pane is lowered and raised. The guide rail has a radius of curvature greater than that of the window pane but smaller than that of the arcuate path and has a center point of curvature concentric with that of the arcuate path, which center point is offset from that of the window pane.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
225 words
A guiding mechanism for guiding a slidable curved window pane during raising and lowering thereof between uppermost and lowermost points through an opening formed in a vehicle door body having inner and outer panels, which window pane has a predetermined radius of curvature, said mechanism comprising, in combination, a curved, elongated guide rail having one end pivotally fixed in the upper portion of the vehicle door body and the other end adjustably positioned in the lower portion of the vehicle door body, at least two sliding rollers mounted on said window pane and slidably engaged with said guide rail for guiding said curved window pane during raising and lowering thereof, and adjusting means provided between the inner panel of said door body and said other end of said guide rail for effecting adjustable positioning of said other end of said guide rail in relation to said inner and outer panels, the curvature of a sliding surface of said guide rail having a center point concentric with a center point of an arcuate path crossing said uppermost and lowermost points and having a radius of curvature smaller than that of said arcuate path but greater than that of said window pane, and said center point of said curvature of the sliding surface of said guide rail being offset from the center point of said window pane.
Claim 2
Dependent Claim
225 words
A guiding mechanism for guiding a slidable curved window pane during raising and lowering thereof between uppermost and lowermost points through an opening formed in a vehicle door body having inner and outer panels, which window pane has a predetermined radius of curvature, said mechanism comprising, in combination, a curved, elongated guide rail having one end pivotally fixed in the upper portion of the vehicle door body and the other end adjustably positioned in the lower portion of the vehicle door body, at least two sliding rollers mounted on said window pane and slidably engaged with said guide rail for guiding said curved window pane during raising and lowering thereof, and adjusting means provided between the inner panel of said door body and said other end of said guide rail for effecting adjustable positioning of said other end of said guide rail in relation to said inner and outer panels, the curvature of a sliding surface of said guide rail having a center point concentric with a center point of an arcuate path crossing said uppermost and lowermost points and having a radius of curvature smaller than that of said arcuate path but greater than that of said window pane, and said center point of said curvature of the sliding surface of said guide rail being offset from the center point of said window pane.
Claim 3
Dependent Claim
267 words
A guiding mechanism for a slidable curved window pane of an automotive vehicle having a folding top on which a weather seal strip is mounted, a door body having an opening and inner and outer panels, said guiding mechanism comprising, in combination, a curved, elongated guide rail having one end pivotally fixed in the upper portion of said door body and the other end adjustably positioned in the lower portion of said door body, at least two sliding rollers mounted on said curved window pane and slidably engages with said guide rail for guiding said curved window pane on said guide rail during raising and lowering thereof through an uppermost point on said folding top, an entrance point at said door body opening and a lowermost point in said door body, and adjusting means located between said inner panel of said door body and said other end of said guide rail for adjusting the position of said other end of said guide rail in relation to said inner and outer panels, said guide rail being positioned in said door body in spaced parallel relationship with respect to an arcuate path crossing said uppermost, entrance and lowermost points and having a radius of curvature greater than that of said window pane but smaller than that of said arcuate path, and the curvature of said guide rail having a center point concentric with that of said arcuate path but offset from the center point of curvature of said window pane, whereby a single travelling path is provided between said uppermost point and said lowermost point on said arcuate path.
Claim 4
Dependent Claim
267 words
A guiding mechanism for a slidable curved window pane of an automotive vehicle having a folding top on which a weather seal strip is mounted, a door body having an opening and inner and outer panels, said guiding mechanism comprising, in combination, a curved, elongated guide rail having one end pivotally fixed in the upper portion of said door body and the other end adjustably positioned in the lower portion of said door body, at least two sliding rollers mounted on said curved window pane and slidably engages with said guide rail for guiding said curved window pane on said guide rail during raising and lowering thereof through an uppermost point on said folding top, an entrance point at said door body opening and a lowermost point in said door body, and adjusting means located between said inner panel of said door body and said other end of said guide rail for adjusting the position of said other end of said guide rail in relation to said inner and outer panels, said guide rail being positioned in said door body in spaced parallel relationship with respect to an arcuate path crossing said uppermost, entrance and lowermost points and having a radius of curvature greater than that of said window pane but smaller than that of said arcuate path, and the curvature of said guide rail having a center point concentric with that of said arcuate path but offset from the center point of curvature of said window pane, whereby a single travelling path is provided between said uppermost point and said lowermost point on said arcuate path.
