  • Patent number: 8968880
    Abstract: A method of bonding a first panel made of a first material to a second panel made of a second material is provided. The method includes creating a second panel hole in the second panel at a weld location. An insert composed of the first material is inserted into the second panel hole in the second panel. At least a portion of the insert is fittable in the second panel hole and sized to correspond to the second panel hole. The first panel and the insert are welded together at the weld location, thereby bonding the first and second panels. In one embodiment, the first and second panels are placed between the first and second electrodes of a welding gun. A force is applied to clamp the insert and the first panel between the first and second electrodes and a welding current is delivered. A bonded structure is provided.

  • Publication number: 20140333088
    Abstract: A single input, multi-output drive system adapted for use, for example, with a power seat or a vehicular door assembly, includes an input power source, such as a PMDC motor, and at least one transmission further including a plurality of output elements shiftable between engaged and disengaged conditions relative to the source, so as to be selectively driven thereby, and drivenly coupled, for example, to various functions of the power seat or door assembly, and a plurality of active material actuators drivenly and individually coupled to an associated one of the output elements, and configured to selectively engage the associated output element and input source.

  • Patent number: 8690204
    Abstract: A closure assembly includes a handle assembly having a grab bar. The grab bar is moveable in a normal direction relative to an exterior panel surface of the closure assembly between a retracted position and an extended position. When in the retracted position, an outboard surface of the grab bar is disposed approximately flush with the exterior panel surface. The closure assembly includes a position sensor configured for sensing the presence of an operator, and signals the handle assembly to move the grab bar into the extended position when the presence of the operator is sensed. When the grab bar is grasped, the handle assembly signals a latch mechanism to move into an un-latched position to allow the closure assembly to open.

  • Publication number: 20130125472
    Abstract: A closure assembly includes a panel that defines an opening. A handle includes a grab bar that is moveable from a retracted position through the opening into an extended position. A cover is coupled to and moveable with the handle. The cover is disposed within the opening and flush with the exterior surface of the panel when in a closed position. When the handle moves from the retracted position into the extended position, the cover moves out of the closed position to allow the handle to pass through the opening. When the handle moves from the extended position into the retracted position, the cover moves into the closed position to close the opening. A closeout is coupled to and moveable with the handle. The closeout moves into an exposed position as the handle moves into the extended position to conceal the remainder of the opening not occupied by the handle.

  • Publication number: 20100321945
    Abstract: A lighting apparatus for an automobile generally includes a projection device coupled to the automobile (e.g., an external component, such as a door handle assembly) wherein the projection device is configured to project an image onto a display surface that is external to the automobile (e.g., the ground adjacent to a door of the automobile or a region near the door handle itself). The lighting apparatus is configured to activate in response to one or more events, such as proximity of a key fob, the unlocking of one or doors, or the like.

  • Patent number: 7665776
    Abstract: An handle assembly for a vehicle door and method of actuating a release mechanism, such as a door latch, are disclosed. The handle assembly may have a pull handle including a sliding leg, a pivot leg and a hand gripping portion extending between the sliding leg and the pivot leg, with the sliding leg adapted to guide the pull handle between a closed position and an open position, and with the pivot leg adapted to be secured for pivoting about a handle pivot axis about which the pull handle is pivotable. The handle assembly may also include a torque cable having a first end centered and rotatable about the handle pivot axis, and a second end adapted to operatively engage the release mechanism, with the first end rotationally fixed to the pivot leg.

  • Patent number: 4800699
    Abstract: A molding/locator and attaching clip device includes a molding retainer clip which is adapted to be secured by a headed stud to a support panel and to which an open channel molding can be secured and, a molding locator clip which is adapted to be secured into a notched flange of the molding. Pawl arms on the molding retainer clip are adapted to engage ratchet teeth on the molding locator clip so that the molding and molding clip can be moved relative to the molding retainer clip in one direction and to prevent movement in the opposite direction.

  • Patent number: 4765673
    Abstract: A window reveal molding includes a C shaped inner member of high durometer plastic material including spaced apart legs which are closer together than the thickness of the window panel so the legs forcibly grip the opposed faces of the window panel. The molding also includes an outer member of low durometer plastic material which is coextruded onto the inner member. The outer member has a C shaped channel portion including legs encapsulating the legs of the inner member and extending beyond into sealing engagement with the window panel. The outer member also has a continuous flexible lip extruded integral therewith and extending therefrom into engagement with either an outer body panel or a recessed portion of a body panel flange when the window panel with the molding attached thereto is installed in the window opening so that the flexible lip bridges across the space between the window panel and the body panel.
