The invention relates to an adjustment armature comprising a fixed component (11) which is associated with part the seat and an adjustable component (12) which is connected to the backrest. The components of the armatures (11, 12) are joined to each other by means of an actuating member (13). An adjusting and locking device, having the form of a gear, is provided in order to adjust the relative positions of the two armature components (11,12). The adjusting member (13) comprises an eccentric segment (14), whereby one of the armature components (12) is mounted thereon. The other armature component (11) acts as a bearing for the eccentric segment (14). The eccentric segment (14) is comprised of wedge segments (27), which rest against each other and partially overlap a catch (20). Said eccentric segment is also provided with a catch segment (29) between the narrow sides thereof and an energy accumulator which moves the wide ends of, the wedge segments (27) apart. The actuating member (13) optionally comprises a central receiving section for a rotationally fixed connection to the transmission rod. The catch (20) is made up of a bushing (21), and a ring (26), which is rotationally fixed to said bushing and consists of a catch segment (29), whereby no free movement can be felt when the armature (10) is initially displaced for adjustment purposes. The catch ring (26) is mounted on the armature component (11) and acts as a bearing for the wedges (27) in a peripheral region of said ring, which does not contain said catch segment (29).
An adjustment armature for motor vehicle seats with an adjustable inclinable backrest, wherein a fixed armature part correlated with the seat part and an adjustable armature part correlated with the backrest are connected to one another by an actuating member, wherein an adjusting and locking device, determining the position of both armature parts relative to one another and configured as a gear, is provided, and wherein the actuating member comprises an eccentric segment on which one of the armature parts is supported while the other armature part supports the eccentric segment, which eccentric segment is comprised of two wedge segments covering partially a driver and inclined relative to one another, of a driver segment engaged between their narrow sides, and of a force storage means forcing the wide sides of the wedge segments apart, wherein the actuating member, has a central receptacle for a fixed connection with a transmission rod, wherein the driver (20) is formed of a driver bushing (21) and a driver ring (26) fixedly connected thereto and the driver segment (29) is defined by the driver ring (26), wherein the driver ring (26) is supported on the armature part (11) and supports, in turn, the wedge segments (27) on its circumferential area (30) free of the driver segment (29).
