Claim:
1. A longitudinal adjuster for the vehicle inner space of a motor vehicle, comprising: an upper rail; a lower rail; at least one roller member provided between the upper rail and the lower rail; and at least one projection provided on the upper rail and at least one projection provided on the lower rail, wherein the projections on the upper rail and the lower rail form local contact points between the upper rail and lower rail, wherein the at least one projection on the upper rail is provided integrally with the upper rail by being shaped from material of the upper rail, wherein the at least one projection on the lower rail is provided integrally with the lower rail by being shaped from material of the lower rail, wherein the projections on the upper rail and the lower rail are stamped or bent, wherein the projections on the upper rail and the lower rail are clamped between the upper rail and the lower rail in order to be resiliently deformable between the upper rail and the lower rail and to compensate for production tolerances, wherein the lower rail includes a central region having a substantially U-shaped cross-section, wherein the central region includes inner sides that face toward one another in a lateral direction and outer sides that face away from one another in the lateral direction, wherein the at least one projection on the lower rail is stamped or bent to extend outward in the lateral direction from the outer sides of the central region, wherein the lower rail includes an outwardly extending portion that extends outwardly from the central region, wherein the outwardly extending portion includes a first surface and a second surface, wherein the first surface and the second surface directly oppose each other through the thickness of the outwardly extending portion, wherein the at least one roller member directly contacts the first surface, wherein the at least one projection on the upper rail is located on an end of an inwardly-extending portion of the upper rail, wherein the inwardly-extending portion is inclined relative to the vertical direction such that the at least one projection on the upper rail directly contacts an intersection between one of the outer sides of the central region and the second surface of the outwardly extending portion of the lower rail, wherein the at least one projection on the lower rail does not extend substantially along the length of the lower rail, wherein the at least one projection on the upper rail contacts the lower rail at a point, wherein the at least one projection on the lower rail contacts the upper rail at a point, wherein the lower rail and the upper rail are configured to directly interlock with and contact one another exclusively at the at least one projection on the upper rail and the at least one projection on the lower rail, wherein the at least one projection on the upper rail and the at least one projection on the lower rail are configured such that the longitudinal adjuster is resilient in substantially the vertical direction, wherein the vertical direction is perpendicular to the longitudinal direction, wherein at least one of the lower rail and the upper rail are adjustable along an axis parallel to the longitudinal direction.
