  sedan 

  1635, "covered chair on poles," possibly from a southern Italian dialect 
  derivative of It. sede "chair" (cf. It. seggietta, 1598; the thing itself was 
  said to have been introduced from Naples), from L. sedes, related to 
  sedere "sit". Since Johnson's conjecture, often derived from the town of 
  Sedan in France, where it was said to have been made or first used, but 
  historical evidence for this is lacking. Introduced in England by 
  Sir Sanders Duncombe in 1634 and first called a covered chair. 
  "In Paris the sedan-chair man was usually an Auvergnat, in London an Irishman" 
  ["Encyclopedia Britannica," 1929]. Meaning:

   "closed automobile seating four or more" first recorded 1912, Amer.Eng.
