  • Patent number: 6464270
    Abstract: An exterior handle assembly for a motor vehicle door including an escutcheon, a handle including a horizontal hand grip and a pair of vertical arms supported on the escutcheon for pivotal movement about a horizontal first axis, and a multiplier lever supported on the escutcheon for pivotal movement about a horizontal second axis. The multiplier lever surrounds one of the vertical arms of the handle for concurrent pivotal movement therewith and is linked by a push rod to a release lever of a door lock such that pivotal movement of the handle to an extended position of the hand grip releases a fork bolt to release the door. The separation between the horizontal first and second axes amplifies the pivotal movement of the multiplier lever.

  • Patent number: 5953963
    Abstract: A motion-transmitting assembly has a cable movable within a tubular sheath anchored on a panel. A movable member, such as a lever, is movably mounted on the support and has an aperture which receives a retainer clip. The retainer clip has a cylindrical body installed into the aperture of the member and having a bore extending through the cylindrical body with yieldable fingers projecting into the bore. A cable fitting has a barrel with a bore slidably receiving the cable. A stud projects laterally from the barrel and has a circumferential groove so that upon insertion of the stud into the bore of the retainer clip, the yieldable fingers of the retainer clip engage with the circumferential groove of the cable fitting to thereby connect the cable fitting with the movable member.
