Abstract

A vehicle seat with a seat part and a backrest structure is provided. The seat part includes a first seat component, at which a second seat component connected with the backrest structure is fixed, when the backrest structure is present in a proper position of use. A deformation device with at least one deformation element fixed at one of the seat components is provided, which in the case of a crash upon exceedance of a specified threshold value of a force acting on the backrest structure permits a displacement of the second seat component relative to the first seat component by deforming the at least one deformation element. The deformation device includes at least one oblong hole which specifies a deformation path along which a displacement of the second seat component is effected after exceedance of the threshold value. A fastening element is provided, which fixes the deformation element and at least one seat component to each other, which with a bearing portion engages into the oblong hole at the other seat component, and which is held in a specified position by the deformation element, when the backrest structure is present in a proper position of use.
