Seat rail pair for a vehicle seat

A seat rail pair for a vehicle seat, the seat rail pair comprising:

• a lower rail;
• an upper rail displaceably guided relative to the lower rail in a longitudinal direction, wherein the upper rail and the lower rail mutually engage with each other, wherein the lower rail has a substantially C-shaped profile and downwardly bent end portions, and wherein the upper rail has a substantially U-shaped profile and upwardly bent end portions;
• a plurality of roller members arranged between the upper rail and the lower rail, wherein at least one of the plurality of roller members is arranged in a first lower roller member raceway in a first outer profile portion of the substantially C-shaped profile of the lower rail, wherein at least one of the plurality of roller members is arranged in a second lower roller member raceway in a second outer profile portion of the substantially C-shaped profile of the lower rail, wherein at least one of the plurality of roller members is arranged in a first upper roller member raceway in the first outer profile portion of the substantially C-shaped profile of the lower rail, wherein at least one of the plurality of roller members is arranged in a second upper roller member raceway in the second outer profile portion of the substantially C-shaped profile of the lower rail, wherein each of the upwardly bent end portions of the upper rail defines a planar support face, wherein each of the planar support faces contacts the at least one of the plurality of roller members arranged in a respective one of the first and second lower roller member raceways, and wherein the first and second lower roller member raceways are raised relative to a substantially planar base of the substantially C-shaped profile of the lower rail via steps formed by the first and second outer profile portions of the substantially C-shaped profile of the lower rail;
• and
• a locking plate adapted to be vertically displaced with respect to the upper and lower rails and extending into the upper rail, wherein longitudinal displaceability of the upper rail relative to the lower rail is limited via a cooperation of an end stop which is arranged in extension of one of the downwardly bent end portions of the lower rail with a stop element which is arranged in a transition region between the substantially U-shaped profile and one of the upwardly bent end portions of the upper rail, wherein the end stop is bent outward and downward, wherein the upper rail has two cutting edges formed therein to limit downward movement of the locking plate, and wherein the two cutting edges are each located above and outside a respective bending radius of the upper rail.
