A vehicle includes a base and a seat rotatable relative to the base. The vehicle includes a helical ramp fixed relative to one of the base and the seat. The vehicle includes a linear variable differential transformer (LVDT) including a housing fixed relative to the other of the base and the seat and a plunger moveably supported by the housing. The plunger contacts the helical ramp.

A vehicle seat assembly is provided and includes a base assembly, a seat frame assembly attached to the base assembly, and a seat tilt control mechanism attached to the base assembly and the seat frame assembly. Actuation of the tilt drive assembly adjusts a tilt position of the seat frame assembly with respect to the base assembly.

The invention relates to a vehicle seat having a roller guide which has at least one guide rail which is at least partially sideways open and at least one running roller rolling in the guide rail, connected to parts of the vehicle seat via an axle member, wherein a running surface of the running roller is rollable along a roller-underside inner wall of the guide rail arranged parallel or at an angle to a middle axle of the running roller, wherein the running roller comprises at least a first area and a second area, wherein the first area forms at least a part of the running surface and the second area is arranged in a radial direction of the running roller at least partially between the axle member and the first area and in contact with both. According to the invention, an electrical conductivity of the first area is lower than an electrical conductivity of the second area.

A pumping device for a seat of a vehicle, in which a cam supporter supports a clutch cam to be balanced in the pumping device, thereby minimizing movement of the clutch cam due to an external force reversely input, and the cam supporter guides movements of brake rollers, thereby causing braking operation by the brake rollers to be precisely performed and improving operating performance.

Proposed is a clutch cam for a pumping device, wherein the shape of the clutch cam and the coupling structure between the clutch cam and parts coupled thereto are changed to reduce manufacturing cost and improve assembly performance. The clutch cam includes: a cam part having a cam profile provided along an outer circumferential surface thereof relative to a rotating axis of a center thereof; a first protrusion part provided on a side of the cam part by protruding therefrom toward the lever bracket on the same rotating axis as the rotating axis, and fitted to a fixing hole provided in the lever bracket; and a second protrusion part provided on the side of the cam part by protruding therefrom toward the lever bracket on the same rotating axis as the rotating axis, and fitted to an angle determination hole provided in the housing.

A seating assembly includes a shell assembly having a seat base coupled with a seatback. A base assembly is operably coupled with the shell assembly. The base assembly includes an outer portion defining an opening and an engagement slot. An inner portion is positioned through the opening of the outer portion. The inner portion includes a sidewall defining a receiving well. A barrel is positioned around the inner portion. The barrel defines a track extending helically from a lower end of the barrel to an upper end of the barrel. A bearing is received by the engagement slot, the receiving well, and the track. The bearing is movable along the engagement slot and the track simultaneously. An actuator is operably coupled with the barrel and is configured to rotate the barrel. Rotation of the barrel is configured to vertically translate the inner portion relative to the outer portion.

A vehicle includes a base and a seat rotatable relative to the base. The vehicle includes a helical ramp fixed relative to one of the base and the seat. The vehicle includes a linear variable differential transformer (LVDT) including a housing fixed relative to the other of the base and the seat and a plunger moveably supported by the housing. The plunger contacts the helical ramp.

The invention relates to a device for influencing a backward movement of a seat (1), in particular a backrest part (1.1) of the seat (1), with at least one deformation element (4) arranged in a hinged area (7) of the seating part (1.2) of the seat (1), the deformation element (4) being configured such that the deformation element can be deformed due to a force acting on the seating part (1.2) and/or the back part (1.1) at a predefined torque curve. The invention also relates to a seat (1), in particular a vehicle seat, comprising a seating part (1.2), a backrest part (1.1) and the type of device.

A motor home seat lift apparatus is provided which is located within the vehicle at the front passenger door, which is foldable to a storage location adjacent to the dashboard and forward of the front passenger seat, and which unfolds for usage to place a lift seat adjacent to the level of the front passenger seat, from which a user can slide onto (or off of) the lift seat. The lift seat is then movable from the that level, downward and outward through the opened front passenger door, to a level comfortably adjacent the ground level, for the user to then stand upon when exiting the lift seat. In general, the apparatus includes a lift seat which moves laterally within the vehicle into and out of the door, and rotates up and down between the exterior ground level and the passenger seat level, above the passenger compartment floor. The lift seat is also rotatable during this lateral and rotational motion, so that the user can be comfortably reoriented to face the direction of motion and avoid impact with other vehicle structure.

It is provided an adjusting device for the longitudinal adjustment of a vehicle seat, comprising at least one rail for defining a longitudinal seat axis along which a seat base of the vehicle seat is adjustable, and for supporting at least one adjusting unit of the adjusting device, and at least two shiftably guided adjusting units arranged one behind the other along the longitudinal seat axis, to which the seat base is to be fixed in order to be adjustable along the longitudinal seat axis. The at least two adjusting units are adjustable relative to each other along the longitudinal seat axis, and each adjusting unit is assigned a separate drive for the power-operated adjustment along the longitudinal seat axis.
