Abstract: The invention relates to an electrical steering device having a ring gear arrangement made of one ring gear (31), at least one flange (32), and at least one damper that couples the ring gear (31) and flange (32), wherein either the damper has a single damper element that is made of metal or that has metal components, or is made of at least a first damper element (34) and at least a second damper element (35; 35°; 35*), the two damper elements (34, 35; 34, 35°; 34, 35*) having different elasticities. The first damper element (34) has a non-linear spring characteristic line (h(34)) and the second damper element (35; 35°; 35*) has a linear or almost linear spring characteristic line (h(35)).

Abstract: The invention relates to a gear composed of an injection-molded material, comprising an internal gate region and an external toothed ring with teeth, wherein each tooth has an external tooth crest and two lateral tooth base segments, at least one locating hole for a driver element engaging from the side, and a weld line of the injection-molded material, wherein the weld line runs from an external wall of the locating hole to the outer circumference of the gear, wherein the weld line runs through the tooth crest of one of the teeth to the outer peripheral surface of the tooth. In addition, an injection-molding method is proposed for the injection molding of such a gear. Due to the path of the weld line through the gear body to the periphery of the tooth, tensile stresses are distributed along a greater distance than is the case in a conventional gear.

Abstract: Motor driven adjustment device with a control unit (2; 2') for controlling a motor driven unit (4) wherein an acoustic signal generator (6, 6') which produces an acoustic signal upon activation of the motor driven unit (4) is coupled at an output (21, 23) of the control unit (2; 2').
