Patent ID: 7661646

Claim:
A locking mechanism for selectively interlocking upper and lower tracks of a seat track assembly, said locking mechanism comprising: a pin carrier having a body and at least one arm having an intermediate portion extending between a proximal end fixedly secured to said body and a distal end, said distal end of said arm having a wider profile than said intermediate portion to define a stop edge; a mounting plate adapted to be fixedly secured to the upper track, said mounting plate having at least one slot having adjacent narrow and wide portions defining a stop surface due to the difference in size between said narrow and wide portions, said wide portion adapted to receive said distal end of said arm therethrough during assembly of said pin carrier and said mounting plate, said narrow portion adapted to slidably receive said intermediate portion arm therethrough for selective sliding movement of said pin carrier relative to said mounting plate, said stop surface engagable with said stop edge of said pin carrier to prevent removal of said arm from said slot; and a plurality of pins slidably coupled to both said pin carrier and said mounting plate for movement in and out of locking engagement with the upper and lower tracks during corresponding movement of said pin carrier relative to said mounting plate.
