  • Patent number: 9428083
    Abstract: The invention relates to a vehicle seat with a roller guide. The roller guide includes at least one guide rail, and at least one roller received in the guide rail. A roller cover part of the roller is rollable with a running surface of the roller. The roller cover part is divided into a first circumferential surface-like functional region and a second circumferential surface-like functional region which are arranged one behind the other in a direction of a shaft of the roller. The first region is deformable by pressurization by seat occupation. The first region is in contact with an inner wall on a lower side of the roller and with an inner wall on the upper side of the roller. An outer diameter of the second region has an undersize with respect to a spacing between the inner wall on the upper and lower sides of the roller.

  • Patent number: 8926012
    Abstract: The invention concerns a vehicle seat for a vehicle with a seating surface (10), a back rest (12) and at least one foot (14) supporting the seating surface (10), wherein the foot (14) is formed by a connecting means assembly (16) comprising two connecting means (18, 20), namely a first connecting means (18) and a second connecting means (20), each running/extending substantially horizontally, which are each coupled and held spaced in the vertical direction by means of two further connecting means (22, 24), namely a third connecting means (22) and a fourth connecting means (24), such that these four connecting means (18, 20, 22, 24) form a frame (26) which can be connected with the vehicle, and that at least one fifth connecting means is a deformation device (36), wherein the first connecting means (18) is arranged in the vertical direction above the second connecting means (20) and the third connecting means (22) is arranged in the vehicle longitudinal direction in front of the fourth connecting means (24).
