GR translation: borne again into the rush-hour crowds

[Mark Kohut]

Lots of resonances here as past participle of 'bear'......

here's #14, w famous use.
 
14. To move by or as if by steady pressure; push: "boats against the current, borne back ceaselessly into the past" (F. Scott Fitzgerald).

P26.25-27  “Hi, glamorpuss,” Slothrop said. Her name was Cynthia. He
managed to get a telephone number before she was waving ta-ta, borne
again into the rush-hour crowds.

What exactly is the meaning of the word "borne" here?
