Abstract
An adjustment device for seats, particularly motor vehicle seats, having a transmission, particularly a planetary gear transmission, and further including a drive shaft (2) which can be rotated by a drive device (4) coupled therewith. The mass moment of inertia acting on the drive shaft (2) can be increased by at least one mass body (15) that is operatively connected with the drive shaft (2).
Claims6
An adjustment device for use in vehicle seats, said adjustment device comprising:
- a drive shaft of a first transmission, which drive shaft can be rotated by means of a hand knob coupled therein, said hand knob having a recess therein;
- a mass body means operatively connected with said drive shaft, for increasing the effective mass moment of inertia of said drive shaft, wherein said mass body means is positioned in said hand knob recess and is formed as an annular element arranged concentrically to said drive shaft supporting said hand knob;
- said annular element supporting at least one pinion having an axis which is parallel to said drive shaft and eccentric thereto, said pinion meshing with a first crown gear provided on said hand knob and also with a second crown gear that is securely connected with one hinge element to form a second transmission which serves as a non-retarding planetary gear transmission.
