From this comparison, an adjusting signal is generated, which is then provided to the adjusting device, which then automatically moves the backrest (3) and/or the warp stop motion (17) automatically into the respective desired position.Type: GrantFiled: May 13, 1999Date of Patent: October 24, 2000Assignee: Lindauer Dornier Gesellschaft mbHInventors: Peter D.
