A knee support is arranged inside a body of the motor vehicle and exhibits a transverse frame member, which extends at right angles to the longitudinal direction of the motor vehicle, is held at rigid, lateral body structures, and is provided with at least one deformation element. This deformation element comprises several hollow brackets, defined by bracket walls, and is covered by a support wall, facing the occupants' knees. The deformation element exhibits a first hollow bracket segment, which runs along the support wall, and a second additional hollow bracket segment, which is arranged at an angle to the first hollow bracket segment, whereby the second hollow bracket segment is attached to the transverse frame member.
