A magnetic resonance coil apparatus has a posterior coil unit. The magnetic resonance coil apparatus having a posterior coil unit includes a base unit, a tilting unit and a force transmission unit. The tilting unit, which includes at least one coupling element, is arranged on the base unit such that the tilting unit can tilt with respect to the base unit. For each coupling element of the tilting unit, the base unit includes at least one corresponding coupling element. The coupling state between the at least one coupling element of the tilting unit and the at least one corresponding coupling element of the base unit can be changed by actuating the force transmission unit.
