  • Windshield wiper with excess load relief
    Patent number: 5050442
    Abstract: A windshield wiper drive link is pivoted indirectly to a crank arm through an intermediate toggle member and a pair of oppositely directed beams cut into the side walls of the drive link stamping. Under excess load, one or the other of the beams will buckle in compression, allowing the drive link to in effect change length, thereby yielding to avoid overload.

  • Drive mechanism for overlapping wipers
    Patent number: 4969227
    Abstract: A drive for overlapping wipers includes a pair of wiper shafts offset to different sides of a drive shaft, each driven by a spatial mechanism, which, by virtue of the offset from the drive shaft, creates a position and speed differential between the wipers that prevents them from colliding at inner wipe.

  • Unitized cowl and wiper arm assembly
    Patent number: 4893865
    Abstract: A unitized cowl and wiper arm assembly includes a blow molded plastic shell structure and two wiper arms of the integral type. At two locations, the shell is reformed so as to create an area of increased stiffness that includes a pair of spaced, overhanging interior flanges. This allows the journal portion of the arms to pass through the shell and be pivoted thereto between the spaced interior flanges. Thereafter, the arm is rigidly and securely supported. The leakproof interior of the shell may also be used for a fluid reservoir.
