Adjustment device in a seat for a pelvis and/or lordosis support in a back support connectable to the seat, with a bowden-cable arrangement connected thereto

An adjustment device, comprising:

• a housing having a radial opening in a sidewall thereof;
• an axially movable spindle supported by said housing, said spindle having a cross bore in a sidewall thereof;
• an adjustment handle in a drivingly connected with said axially movable spindle for infinitely adjusting the axial position of said spindle relative to said housing;
• wherein said housing and said spindle each have an axial central bore for receiving a cable of a Bowden-cable arrangement, said central bores being aligned with each other, the central bore in said spindle ends in an interior space of said spindle for receiving a nipple attached to one end of said cable, said radial opening and said cross bore being aligned with each other in a mutual position of the housing and the spindle forming a common passage permitting insertion of said nipple into said interior space, said radial opening being connected with said central bore of said housing by a first slot and said cross bore being connected with said central bore of said spindle by a second slot, said first and second slots being disposed in a common plane for permitting passage of said cable.

An adjustment device, comprising:

• a housing;
• an axially movable spindle supported in said housing, said spindle having a cross bore in a sidewall thereof;
• an adjustment handle drivingly connected with said axially movable spindle for infinitely adjusting the axial position of said spindle relative to said housing;
• wherein said spindle has an axial central bore for receiving a cable of a Bowden-cable arrangement, wherein the central bore ends in an interior space of said spindle for receiving a nipple attached to one end of said cable, said cross bore forming a passage for permitting insertion of said nipple into said interior space, said cross bore being connected with said central bore of said spindle by a slot for permitting passage of said cable.

An adjustment device, comprising:

• a housing;
• an axially movable threaded spindle supported in said housing, said spindle having a cross bore in a sidewall thereof;
• an adjustment handle connected to a threaded ring drivingly connected with said axially movable spindle for infinitely adjusting the axial position of said spindle relative to said housing;
• wherein said spindle has an axial central bore for receiving a cable of a Bowden-cable arrangement, wherein the central bore ends in an interior space of said spindle for receiving a nipple attached to one end of said cable, said cross bore forming a passage for permitting insertion of said nipple into said interior space, said cross bore being connected with said central bore of said spindle by a slot for permitting passage of said cable.
