Abstract: The invention relates to an orthopedic system having a leaf spring element (40) and a bearing component (600) supported on the main surface of the spring element and being fixable to the leaf spring element. At least one elastomeric element (71, 72) is arranged between the bearing component and the main surface of the leaf spring element and is fastened to the leaf spring element and the bearing component such that it transfers shearing forces.

Abstract: A column with at least one photovoltaic element for converting radiation energy is disclosed. The at least one photovoltaic element converts radiation energy of light, such as sunlight, into electrical energy. The at least one photovoltaic element is arranged on the column, and at least one photovoltaic element is a flexible photovoltaic element.

Abstract: The invention relates to a prosthetic foot with a foot part 2 and a lower leg part 4 that is connected to the foot part 2 such that it can be pivoted about a pivot axis 6 and that can be locked in various pivot angles relative to the foot part 2, the connection between the lower leg part 4 and the foot part 2 having a clearance in the pivot direction when the foot part 2 is locked on the lower leg part 4, the prosthetic foot having at least one friction element 14 arranged between the foot part 2 and the lower leg part 4 and applying a frictional torque that counteracts a pivoting of the foot part 2 relative to the lower leg part 4 when the foot part 2 is locked relative to the lower leg part 4.
