1. A vehicle seat comprising a seat part and a backrest,
wherein the backrest comprises a lumbar support, wherein the lumbar support has a plate-like structure and is made from a plastic material, wherein the lumbar support extends over an entire length of the backrest, wherein the lumbar support has a lumbar apex towards a back of a seat occupant and tapers from there and that the lumbar support comprises a suspension that results in a distribution of a load uptake with a primary load uptake at the lumbar apex, wherein the lumbar support has three spring regions comprising a first spring region, a second spring region, and a third spring region, wherein the first spring region is provided in a region below the lumbar apex, wherein the second spring region is arranged in a region of a shoulder of the seat occupant, wherein the third spring region is a pair of opposing primary grounding elastic elements in an apex region of the vehicle seat, wherein the pair of opposing primary grounding elastic elements are C-shaped and protrude outside a main plane of the plate-like structure, wherein corresponding ends of the opposing primary grounding elastic elements are oriented toward each other, wherein the three spring regions deform elastically in an event of a rear impact, wherein at least one of the three spring regions is cantilevered, and wherein the lumbar apex is free of a spring region being cantilevered so that deflection is minimal at the lumbar apex.
