Abstract:
An automotive vehicle 10 has a power operated lift-gate 12 that is opened and closed by two drive units 20. The typical drive unit 20 has a guide channel 24, an attachment assembly 30 that is disposed in the guide channel, a flexible drive member 46 that is attached to the attachment assembly and formed in a loop for moving the attachment assembly in the guide channel. The flexible drive member 46 is trained solely around two pulleys 42, 44 at the respective opposite ends of the guide channel to form the flexible drive member in a narrow loop. One of the pulleys 44 is an idler pulley that is part of an adjustable pulley assembly 60 and the other pulley 42 is driven by a power unit 48 that is attached to the guide channel. The adjustable pulley assembly 60 adjusts the distance between the pulleys 42, 44 to take up slack in the flexible drive member 46.
Abstract:
A drive assembly (42) for a vehicle door (14), comprising: a motor (60) having a driving member (62); a housing having a shaft (68) rotatably received therein; an input member (64) being rotatably received upon the shaft, the input member being operatively associated with the driving member, wherein rotation of the driving member causes rotation of the input member; an armature (73) mounted on the input member; a rotor (72) fixedly secured to the shaft, the rotor being cylindrical in shape and has a plurality of teeth (75) positioned along the periphery of the rotor, the teeth being positioned in an equidistant manner; a coil (70) mounted to the housing, the coil providing magnetic flux lines through the rotor to attract the armature when the coil is energized; and an inductance sensor assembly (80) mounted to the housing in a facing spaced relationship with respect to the plurality of teeth of the rotor, wherein rotational speed and direction of the rotor is detected by the inductance sensor assembly.

Abstract:
An adjustable pedal assembly (10) includes a support structure (12) adapted to connect to a vehicle, with the support structure defining first and second slots (14, 16) arranged in a spaced-apart manner. A pedal assembly (18) is disposed adjacent the support structure (12), where the pedal assembly (18) includes a pedal (20). First and second pins (22, 24) extend from the pedal assembly (18) through the first and second slots (14, 16) whereby the pedal assembly (18) is supported for sliding movement on the support structure (12) along the slots (14, 16). A linear actuator (26) is interconnected with the pedal assembly (18) for sliding the pedal assembly (18) to a desired position along the support structure (12). The invention may be adapted for use in connection with brake pedals, clutch pedals, and accelerator pedals. In the case of accelerator pedals, the invention can be adapted for use with conventional pedals as well as electronic throttle control pedals.
