First Claim
1. A spectacle frame with ear bends each comprising an auricular front member connected to a temple, an auricular back member, a connecting member that connects said front member and said back member rotatably, and a mechanism having first and second stable states at opposite sides of an unstable or quasi-stable state, said first stable state being a state in which said back member is near the back of an ear, and said second stable state being a state in which said back member is remote from the back of the ear, said mechanism being operable between said first and second stable states by rotation of said back member with respect to said front member, and wherein said mechanism includes a device that biases said back member toward the back of the ear in said first stable state and that biases said back member away from the back of the ear in said second stable state.

- 13. A spectacle frame with ear bends each comprising an auricular front member connected to a temple, an auricular back member, and a connecting member that connects said front member and said back member rotatably, said back member being rotatable with respect to said front member between a first position in which said back member is near the back of an ear and a second position in which the back member is remote from the back of the ear, and further comprising a device that biases said back member toward said second position when a wearer of the spectacle frame rotates said back member from the first position past a position intermediate said first and second positions, and that biases said back member toward the first position when the wearer rotates said back member from said second position past a position intermediate said first and second positions.
