A vehicle door latch has a power operated release mechanism for moving a detent from a latched position to a release position comprising a slide that engages the detent at one end and a rotary cam that engages an opposite end of the slide sot that the slide reciprocates when the rotary cam is rotated by an electric motor. The electric motor drives the cam via a concentric gear wheel that has a pin engaging the rotary cam. A forkbolt rotates a rotary block out lever from a by-pass position to a block out position where the block-out lever engages a shoulder of the gear wheel to stop rotation of the gear wheel when the forkbolt is moved to an unlatched position. The vehicle door latch also includes a mechanical override mechanism to rotate the rotary cam to unlatch the vehicle door latch.

A seal assembly as defined in claim 3, wherein said nose portion includes on an axially inner end thereof, a radial flange to distribute the axial load placed on said nose portion. 5. A seal assembly as defined in claim 3, wherein said portion includes an axially outer end thereof, a radial flange to engage said second seal assembly. 6. A seal assembly adapted to be received over a rod movable along a given axis, said seal assembly including an annular metal casing portion and an annular elastomeric body portion, said metal casing portion including a first, generally axially extending radially inner portion having a tail portion adapted to be swaged into a first groove in said rod and another portion adapted to overlie and snugly confine a locking ring received in a second groove, and a second portion for receiving said annular elastomeric body portion, said elastomeric body portion being bonded to said second portion, said elastomeric body portion further including a pair of oppositely directed lip portions separated by a reduced diameter intermediate portion, said seal assembly further including an annular, axially extending nose portion with an annular tip adapted to engage a portion of a second seal assembly and exert an axial force thereon to seat said second seal and allow said second seal to snugly engage the periphery of said rod, wherein said second portion for receiving said elastomeric body comprises first and second radial flanges, said first flange extending raidally outwardly and said second flange extending radially inwardly, said flanges being joined to each other by a bight portion. 7. A seal assembly as defined in claim 6, wherein said seal assembly further includes a second axial flange permanently affixed to said second radial flange, said second axial flange having an upturned end portion serving as said annular tip portion, said second axial flange serving as said nose portion of said assembly. 8. A seal assembly adapted to be received over a rod movable along a given axis, said seal assembly including an annular metal casing portion and an annular elastomeric body portion, said metal casing portion including a first, generally axially extending radially inner portion having a tail portion adapted to be swaged into a first groove in said rod and another portion adapted to overlie and snugly confine a locking ring received in a second groove, and a second portion for receiving said annular elastomeric body portion, said elastomeric body portion being bonded to said second portion, said elastomeric body portion further including a pair of oppositely directed lip portions separated by a reduced diameter intermediate portion, said seal assembly further including an annular, axially extending nose portion with an annular tip adapted to engage a portion of a second seal assembly and exert an axial force thereon to seat said second seal and allow said second seal to snugly engage the periphery of said rod, wherein said second portion includes a first axially extending flange portion, a second axially extending flange portion joined to each other by a bight portion, and a radial flange portion, said elastomeric body being bonded to said radial flange portion and said bight comprising said tip of said nose portion. 9. A two-piece seal assembly adapted to be received over a rod movable along a given axis, said seal assembly including a first piece comprising an annular metal casing portion and an annular elastomeric body portion, said metal casing portion including a first, generally axially extending radially inner portion having a tail portion adapted to be swaged into a first groove in said rod and another portion adapted to overlie and snugly confine a locking ring received in a second groove, and a second annular metal casing portion comprising a radially extending portion and an axially extending portion for receiving said annular elastomeric body portion, said
