Claims3
In a vehicle latch assembly of the type in which a molded plastic operating lever is shifted by an operating rod having a circumferential groove thereon, the improvement comprising:
- said operating lever having a bushing portion integrally molded in one piece continuous molded together construction with the molded plastic lever and having a bore for receiving the rod, retaining fingers molded integral with the bushing portion and projecting into the bore to grip the circumferential groove of the rod, a frangible web molded integral in connection between the bushing portion and the lever so that the lever predeterminately fractures at the frangible web in the event of excessive force application to the lever upon attempted disassembly of the rod from the bushing.
In a vehicle latch assembly of the type in which a molded plastic operating lever is shifted by an operating rod having a circumferential groove thereon, the improvement comprising:
- said operating lever having a bushing portion integrally molded in one piece continuous molded together construction with the molded plastic lever and having a bore for receiving the rod, retaining fingers molded integral with the bushing portion and projecting into the bore to seat within the circumferential groove of the rod, a frangible web molded integral in connection between the bushing portion and the lever, and a slot between the bushing portion and the lever adapted to receive a tool by which the bushing portion can be translated axially within the bore relative to the lever to fracture the frangible web and permit removal of the bushing and subsequent replacement of the bushing by a replacement bushing.
In a vehicle latch assembly of the type in which a molded plastic operating lever is shifted by an operating rod having a circumferential groove thereon, the improvement comprising:
- said operating lever having an annular boss at the end of the lever, a bushing portion integrally molded in one piece continuous molded together construction with the molded plastic lever and within the annular boss and having a bore for receiving the rod, retaining fingers molded integral with the bushing portion and projecting into the bore to grip the circumferential groove of the rod, a frangible web molded integral in connection between the bushing portion and the lever, a slot between the bushing portion and the lever adapted to receive a tool by which the bushing portion can be translated axially relative to the lever to fracture the frangible web and permit removal of the bushing, and a replacement bushing adapted to snap-fit within the annular boss to permit the reinstallation of the rod to the lever by insertion of the rod into the replacement bushing.
