RAIL-CONTROLLED ADJUSTMENT DEVICE COMPRISING A MULTIPART SUPPORTING SUBASSEMBLY

摘要

The invention relates to a rail-controlled adjustment device for a window pane in a motor vehicle, comprising a supporting subassembly (1, 2), at least two guide rails (13, 21, 22) which are disposed on the supporting subassembly (1, 2), define an adjustment path for an adjustable window pane, and are located at a distance from one another transverse to the adjustment path, and a driving member (3) that includes means for connecting the window pane to be adjusted and engages with the guide rails (13, 21, 22) as to be movable in the longitudinal direction. The supporting subassembly (1, 2) consists of at least two support elements (1; 2) which are interconnected at a plurality of securing points (120, 121, 122, 123). According to the invention, on at least one support element (2), securing points (120, 121, 122, 123) by means of which said support element (2) is to be secured to another support element (1) of the supporting subassembly are interconnected by reinforcement paths (25, 26, 27, 28, 29).
