Device for adjusting automobile seats

Claim 1

A device for adjusting a plurality of parts of an automobile seat, comprising: a selection device for selecting at least one of said parts, an electric motor for adjusting at least two of said parts, which motor is movable in two directions of rotation, a plurality of movement converters at least indirectly adjusting respective ones of said parts, at least one output shaft between said electric motor and said movement converters, a switch mechanism having an input and at least two outputs, a first driveshaft leading from said electric motor to said input of said switch mechanism, a second driveshaft leading from one of said outputs of said switch mechanism to a respective movement converter, a changeover device in said switch mechanism which can change over selectively from said input to a selected one of said outputs, and a selection line leading from said selection device to said switch mechanism and connected operatively to said changeover device, wherein said switch mechanism comprises a central shaft forming said input, a first gearwheel fastened non-rotatably on said central shaft, a plurality of third gearwheels provided axis-parallel and at an equal distance from said central shaft, a plurality of shafts, on which said third gearwheels are fastened non-rotatably, forming said outputs of said switch mechanism, said changeover device comprises a cage rotatably supported on said central shaft and a second gearwheel supported by said cage, which meshes with said first gearwheel, said switch mechanism further comprises a frame in which said shafts of said third gearwheels are mounted and in which said cage is mounted rotatably, said cage is rotatable by means of said selection line, and said second gearwheel meshes with one of said third gearwheels in each of a plurality of switch positions of said selection device, said cage comprises two parallel disks of a larger and a smaller diameter respectively and having inner faces, cross members hold said disks at a distance from one another and said inner faces of said disks at least indirectly limit axial moveability of said first and second gearwheels, said disk of larger diameter having teeth on its outer circumference forming a toothed rim as part of said changeover device operatively connected to said selection line, said frame comprises a front plate and a rear plate parallel to each other at a distance to enclose said cage and said third gearwheels, said shafts supporting said third gearwheels and said first shaft supporting said first gearwheel being rotatably supported in both said front plate and said rear plate, and a shaft rotatably supporting said second gearwheel is mounted in both of said disks of said cage.

Claim 2

A device for adjusting a plurality of parts of an automobile seat, comprising: a selection device for selecting at least one of said parts, an electric motor for adjusting at least two of said parts, which motor is movable in two directions of rotation, a plurality of movement converters at least indirectly adjusting respective ones of said parts, at least one output shaft between said electric motor and said movement converters, a switch mechanism having an input and at least two outputs, a first driveshaft leading from said electric motor to said input of said switch mechanism, a second driveshaft leading from one of said outputs of said switch mechanism to a respective movement converter, a changeover device in said switch mechanism which can change over selectively from said input to a selected one of said outputs, and a selection line leading from said selection device to said switch mechanism and connected operatively to said changeover device, wherein said switch mechanism comprises a central shaft forming said input, a first gearwheel fastened non-rotatably on said central shaft, a plurality of third gearwheels provided axis-parallel and at an equal distance from said central shaft, a plurality of shafts, on which said third gearwheels are fastened non-rotatably, forming said outputs of said switch mechanism, said changeover device comprises a cage rotatably supported on said central shaft and a second gearwheel supported by said cage, which meshes with said first gearwheel, said switch mechanism further comprises a frame in which said shafts of said third gearwheels are mounted and in which said cage is mounted rotatably, said cage is rotatable by means of said selection line, and said second gearwheel meshes with one of said third gearwheels in each of a plurality of switch positions of said selection device, said cage comprises two parallel disks of a larger and a smaller diameter respectively and having inner faces, cross members hold said disks at a distance from one another and said inner faces of said disks at least indirectly limit axial moveability of said first and second gearwheels, said disk of larger diameter having teeth on its outer circumference forming a toothed rim as part of said changeover device operatively connected to said selection line, said frame comprises a front plate and a rear plate parallel to each other at a distance to enclose said cage and said third gearwheels, said shafts supporting said third gearwheels and said first shaft supporting said first gearwheel being rotatably supported in both said front plate and said rear plate, and a shaft rotatably supporting said second gearwheel is mounted in both of said disks of said cage.
