Abstract: A cable deflecting piece, which is fastened on a rail head or rail foot of a guide rail and is intended for a cable operated window lifter, contains a base body which during mounting and following fastening of the cable deflecting piece, abuts against the guide rail on one side of the rail head or rail foot, also contains a rotary and bearing pin, which projects from the base body, can be inserted in a position in which it is tilted in relation to the longitudinal extension of the guide rail, into a rotary and bearing opening of the rail head or rail foot and can be pivoted about a cable deflecting piece, further contains a rotation prevention means which, in a final mounting position, once the cable deflecting piece has been pivoted about the mounting axis of rotation, secures the connection of the cable deflection piece to the rail head or rail foot such that the cable deflecting piece cannot rotate and additionally contains a device which is formed on the basic body and is intended for securing the abutmen

Abstract: A method for controlling a synchronous motor driven adjustment device is used in motor vehicles by means of an electronic control, especially for controlling adjustment devices with an anti-trap protection and/or with an excess force limitation. The method includes evaluating variables correlating to the dynamics of the adjusting device or the position of the adjustment member and generating control signals based on the variables, controlling the adjustment rate of the adjustment member to a constant value, and setting a phase displacement between an exciting field and a rotating field of the motor to provide torque to the drive unit based on the load angle at which the torque reaches a maximum.

Abstract: A guide rail 10 for a cable or Bowden cable window lifter with a guide area 1 with slide faces 11, 12 for holding and the sliding guide of a follower mounted displaceable on the guide rail 10 and with at least one fastening area 31, 32 for connecting the guide rail 10 to a fixing base of a vehicle door is made at least in part of plastics and has a reinforcement area 2 connected to the guide area 1 and with reinforcement elements 20 of ribs and/or webs which are moulded on a surface of the reinforcement area 2 preferably integral and substantially perpendicular to the surface of the reinforcement area 2. The at least one fixing area 31, 32 is part of the reinforcement area 2 and the rear sides of the slide faces 11, 12 of the guide area 1 are not directly connected to the reinforcement elements (20). (FIG. 1).
