The cushion element includes a deformation element that is plastically deformable for receiving kinetic energy, where the deformation element is surrounded by a cushion material of the cushion element. Upper and lower sides of the cushion material are connected with each other via a recess of the deformation element. A chamfer is arranged at a side of the deformation element.
