Abstract: A window regulator assembly particularly adapted for motor vehicle applications having a pulley assembly featuring snap in insulation of a pulley ring into a pulley housing. The pulley housing features the clearance area and a number of retention tabs and hooks which enable the pulley ring to be snap fit into position. The assembly may be implemented with a discrete window regulator or as part of a modular inner door plate as well as and for other applications.

Abstract: A glass removal tool for removing a glass panel from a window regulator clamp includes a horizontal cross bar; two parallel legs extending downward from the cross bar; at least one pair of ramps arranged between the parallel legs; and a vertical slot extending between the ramps of the pair of ramps. Two pairs of ramps may be included that are laterally offset from each other. The ramps may be recessed from the front surface and form at least one pair of wedges with the rear surface. The legs may include a first taper formed on the inner surface of each of the legs toward bottom ends of the legs and a second taper formed on the rear surface of the legs toward bottom ends of the legs.

Abstract: A bearing-shaft assembly includes a shaft having a first cylindrical section and a second cylindrical section axially separated by a first annular groove. A bearing is arranged around the annular groove and axially overlaps with the first and second cylindrical sections. A first bushing fills a radial gap between the inner race of the bearing and the first cylindrical section. The first bushing has a first radial collar radially overlapping with the inner race and axially overlapping with the first cylindrical section. A second bushing fills a radial gap between the inner race and the second cylindrical section. The second bushing has a second radial collar radially overlapping with the inner race and axially overlaps with the second cylindrical section. The second bushing fills the first annular groove and is made of a softer material than the first bushing.

Abstract: A window regulator assembly is described that comprises a window bracket that is in contact with the bottom edge of the window; a cable; a carrier plate that is in contact with the window bracket and both ends of the cable; a tension spring located on each end of the cable; an upper bracket assembly; a drum housing having a cable drum; a hollow conduit located between the upper bracket assembly and the drum housing; and a drive unit. The upper bracket assembly, cable drum, and conduit are capable of slideably receiving the cable, while the tension springs provide a predetermined amount of tension to the cable in order for the window regulator assembly to move the window between open and closed positions. Many of the components of the window regulator assembly may be formed from a thermoplastic material.

Abstract: A window carrier assembly for an automotive window regulator. The carrier assembly is a composite assembly of a center body section preferably formed of injection molded plastic material and a pair of window clamps that are snap assembled to the carrier body section. The window regulator assembly preferably is used in connection with a single rail-type window regulator. The body section of the carrier assembly features a cable end receiving socket which allows both ends of the drive cable to be installed in a manner which can be done rapidly in component assembly.

Abstract: The present specification provides a rear window assembly for a vehicle having a window frame, at least one fixed window panel whose perimeter edge defines a portion of an opening, a movable window panel capable of opening or closing the opening and that is allowed to slidably move past the surface of the fixed window panel, a seal member present on the perimeter surface of at least one of the window panels, and a closure track integrally formed in at least one edge of the window frame. The closure track may force the movable window panel and the fixed window panel closer together, thereby, placing the seal member under compression.

Abstract: The present invention concerns a glass attachment and method of assembly for a movable vehicle window, particularly in a vehicle door. A pair of glass clips are attached to a window glass, and a pair of carriers are mounted and retained in a door by cable sets. A snap-in installation is performed by sliding camming guide shoulders on the carriers into channels formed by cam engagement flanges on the glass clips. As the camming action takes place, the carriers are lifted into use positions and catches on the glass clips engage catch openings on the carriers to secure the components together. Grooves in the carriers direct the cable sets, the ends of which are retained in the carriers by ferrules and cable take-up springs.

Abstract: An integrated gas strut actuator assembly particularly adapted for providing power actuation of a motor vehicle lift gate or other opening closure. The assembly integrates the function of a counterbalancing gas spring and that of a electrically powered actuator. The integrated gas strut assembly includes a gas charged cylinder, internal plunger and a threaded rod. Rotation of the threaded rod through a cable drive system causes the internal plunger to be advanced or retracted within the cylinder. Other features of the invention are various embodiments of couplers between the plunger and rod and connectors for connecting the assembly to the vehicle.

Abstract: A method and apparatus for evaluating window regulators of the type having a reversible electric motor connected to a slide/carrier plate by means of cables. The apparatus comprises a first transducer such as a piezoelectric accelerometer or a laser for generating a first signal quantity related to periodic noise produced by the motor during operation thereof, a second transducer such as a piezoelectric accelerometer for producing a second signal quantity representing transient noise produced by irregularities in the slide/carrier plate assembly during travel of the carrier plate along the slide, and a processor for decoding the first and second waveforms and using data derived therefrom as a basis for identifying unacceptably noisy window regulator assemblies. The method comprises placing the window regulators on a test fixture, operating the window regulator with a simulated glass load, and generating and processing the first and second signal quantities as described above.
