Seat rail pair for a motor vehicle seat comprises a lower rail profile and an upper rail profile which are symmetrical to a plane defined by the longitudinal direction of the rails and the horizontal in an interaction region

摘要

Seat rail pair comprises a lower rail (3), an upper rail (4) sliding relative to the lower rail in the longitudinal direction, and balls (40) arranged between the lower and upper rails in an interaction region (13, 15, 17, 28, 30, 32). The profiles of the rails engage in each other. At least in the interaction region the lower rail profile and the upper lower rail profile are symmetrical to a plane defined by the longitudinal direction of the rails and the vertical. In the interaction region the lower rail profile and the upper lower rail profile are symmetrical to a plane defined by the longitudinal direction of the rails and the horizontal. An independent claim is also included for a vehicle seat, especially a motor vehicle seat, comprising two seat rail pairs. Preferred Features: The balls are in contact with ball tracks (36, 38) formed in an angled region of the upper rail.
