Articulated connector device, and padding holder with an articulated connector device of this type

Articulated connector device, wherein the connector device has a first joint arm, a second joint arm and a connecting arm, wherein the first joint arm has a first bearing portion, wherein the first joint arm is mounted with its first bearing portion in the connecting arm pivotably about a first pivot axis, and wherein the second joint arm has a second bearing portion, wherein the second joint armis mounted with its second bearing portion in the connecting arm pivotably about a second pivot axis, wherein the first pivot axis and the second pivot axis (run parallel to one another, wherein the connector device has a clamping unit, wherein the clamping unit is mounted in the connecting arm, wherein the clamping unit has a front clamping jaw and a rear clamping jaw, wherein the clamping jaws can be fed in towards one another along an infeed direction for fixing the first joint arm and the second joint arm in their respective pivot position with respect to the connecting arm,

• wherein the first bearing portion has a convexly curved first clamping surface which runs concentrically with respect to the first pivot axis, wherein the front clamping jaw has a first mating clamping surface, and the rear clamping jaw has a further first mating clamping surface, wherein the first mating clamping surface and the further first mating clamping surface are concavely curved in each case in a complementary manner with respect to the first clamping surface, in such a way that, when the clamping jaws are fed in towards one another, the first mating clamping surface and the further first mating clamping surface come into contact in each case over their full area with the first clamping surface and interact in a non-positive manner with the latter for fixing the first joint arm such that it cannot rotate with respect to the connecting arm,
• wherein the second bearing portion has a convexly curved second clamping surface which runs concentrically with respect to the second pivot axis, wherein the front clamping jaw has a second mating clamping surface, and the rear clamping jaw has a further second mating clamping surface, wherein the second mating clamping surface and the further second mating clamping surface are concavely curved in each case in a complementary manner with respect to the second clamping surface, in such a way that, when the clamping jaws are fed in towards one another, the second mating clamping surface (412) and the further second mating clamping surface come into contact in each case over their full area with the second clamping surface and interact in a non-positive manner with the latter fixing the second joint arm such that it cannot rotate with respect to the connecting arm.
