Vehicle seat with a roller guide
First Claim
1. A vehicle seat with a roller guide, wherein the roller guide has at least one at least partially laterally open guide rail and at least one running roller rolling in the guide rail and connected to parts of the vehicle seat by means of at least one axle, wherein the guide rail comprises a roller bottom-side inner wall arranged parallel to a central axis of the running roller, extending parallel thereto a roller top-side inner wall and a roller outer-side inner wall arranged perpendicularly to the central axis,wherein at least one lower transition inner wall is arranged between the roller bottom-side inner wall and the roller outer-side inner wall and at least one upper transition inner wall is arranged between the roller top-side inner wall and the roller outer-side inner wall,wherein the transition inner walls are configured free from a right-angled portion and in directions from the roller top-side inner wall and the roller bottom-side inner wall towards the roller outer-side inner wall are configured with a continuously reducing spacing from the central axis of the running roller,wherein on an axial loading of the roller guide in a direction of the central axis of the running roller, a lower portion of an outer end portion at a first end of the running roller configured to face the roller outer-side inner wall lies with contact against the lower transition inner wall, andwherein a roller cover of the running roller is rollable along the roller bottom-side inner wall of the guide rail, wherein the roller cover of the running roller is configured at least into a first cover surface functional region which forms the first end of the running roller and has the outer end portion, and a second cover surface functional region arranged therebehind in the direction of the axis of the running roller, said second functional region forming a second end of the running roller facing away from the roller outer-side inner wall.
