Patent ID: 7789464

Claim:
A fitting for a vehicle seat, the fitting comprising: a first fitting part and a second fitting part, wherein there is geared connection between the first fitting part and the second fitting part so that there can be relative rolling between the first fitting part and the second fitting part, and an output side of the fitting comprises the first fitting part; an eccentric that is rotatably mounted on the first and second fitting parts, wherein the eccentric is for being driven, and the eccentric is for causing the relative rolling between the first fitting part and the second fitting part in response to the eccentric being driven; a driver for driving the eccentric so that the eccentric causes the relative rolling between the first fitting part and the second fitting part, wherein the driver is mounted for being rotated in opposite first and second directions; a first wrap spring brake including a first wrap spring arm and a second wrap spring arm, wherein the fitting is configured so that the eccentric acts upon the first arm of the first wrap spring brake to activate the first wrap spring brake in response to a first torque being introduced at the output side of the fitting during an inoperative state of the fitting, so that the first wrap spring brake locks the fitting against the first torque to thereby restrict relative rolling between the first fitting part and the second fitting part during the inoperative state of the fitting, and the driver acts upon the second arm of the first wrap spring brake to release the first wrap spring brake in response to the driver being rotated in the first direction for driving the eccentric; a second wrap spring brake including a first wrap spring arm and a second wrap spring arm, wherein the fitting is configured so that the eccentric acts upon the first arm of the second wrap spring brake to activate the second wrap spring brake in response to a second torque, which is directed oppositely to the first torque, being introduced at the output side of the fitting during the inoperative state of the fitting, so that the second wrap spring brake locks the fitting against the second torque to thereby restrict relative rolling between the first fitting part and the second fitting part during the inoperative state of the fitting, and the driver acts upon the second arm of the second wrap spring brake to release the second wrap spring brake in response to the driver being rotated in the second direction for driving the eccentric; and a bushing that remains stationary with respect to the second fitting part, wherein the first wrap spring brake bears against the bushing, the bushing has a plurality of radially protruding arms, the arms of the bushing engage with a positive fit in an inner toothing of the second fitting part, and the inner toothing partially defines the geared connection between the first fitting part and the second fitting part.
