Patent ID: 8549958

Claim:
An automatic bicycle pedal, comprising a pedal body equipped with: first attachment means at a first end, second attachment means at a second end opposite to the first end, and an elastically deformable lever bearing the second attachment means and capable of being deformed between a first position in which a cleat fixed to the underside of a shoe is held between the first and second attachment means and a deformed second position allowing the cleat to be attached and detached in respect of attachment and detachment movements, characterized in that: the deformable lever comprises: a first blade provided with an end hook comprising: a transverse clip-in ramp for deforming the first blade upon attachment, and a transverse end-stop intended to hold the shoe vertically, a lateral blade arranged on each side of the first blade, the first blade having a smaller thickness and a greater width than the lateral blades, at least one first deformable zone that can be deformed during attachment and detachment movements and at least one second deformable zone that can be deformed during one of the attachment and detachment movements, the first and second zones having different stiffnesses wherein the at least one second deformable zones have a relatively higher stiffness than the first deformable zones.
