Abstract
A detent assembly (30) includes a rotatable index member (34) having a series (44) of minor index positions (46) disposed in a circular array and a series (52) of major index positions (54) disposed in a circular array which is axially offset from the circular array of minor index positions. A plurality of first spring sections (124) are integrally formed as one piece with a housing (32) which encloses the index member (34). The first spring sections (124) are disposed in a circular array which extends around the index member (34). Each of the first spring sections (124) is disposed in engagement with the series (44) of minor index positions (46). A second spring section (66) is integrally formed as one piece with the housing and is disposed in engagement with the series (52) of major index positions (54). A stem (40) extends axially from one end of the index member (34) and is engageable by a handle. A pair of connector arms (82 and 84) extend from the opposite end of the index member (34) and are engageable with a pulley (22) to enable force to be transmitted from the handle through the index member to the pulley.
