Longitudinal adjuster for a vehicle seat, and vehicle seat

摘要

A vehicle seat longitudinal adjuster includes a lower rail (5) and an upper rail (3) which is guided therein such that it can be displaced in the longitudinal direction, and at least one bearing element (30) which is arranged between the upper rail (3) and the lower rail (5) and is in contact with the upper rail (3) and the lower rail (5). At least one additional supporting element (20) is provided which is in contact with the upper rail (3) and the lower rail (5) and has a rotatable supporting roller (22). The supporting roller (22) can be rotated about a rotational axis (A) which runs in the vertical direction. The at least one supporting element (20) includes a supporting spring (26) which loads the supporting roller (22) in the vertical direction. A vehicle seat (1) with the longitudinal adjuster is also provided.
