Abstract

A vehicle seat may have a seat part which can be moved from a usage position into a non-usage position, a seat back, a base, and a seat kinematics connecting the seat part pivotably to the base. The seat kinematics may have a rocker which by a first rotary joint is deflected pivotably on an adapter connected to the base and by a second rotary joint is deflected pivotably on the seat part. A spacing between the base and the seat part can be changed by selection of a first articulation point for articulation of the first pivot joint on the adapter fixedly connected to the base, and/or by selection of a second articulation point for articulation of the second pivot joint on the seat part. A method for assembling such a vehicle seat is also provided.

Description

FIELD The invention relates to a vehicle seat, in particular motor vehicle seat, the vehicle seat having a seat part which is transferable from at least one use position, suitable for conveying a passenger, to at least one non-use position and back; a backrest, in particular a backrest articulated on the seat part; a base which is connectable to a vehicle floor; and a seat kinematics which pivotably connects the seat part to the base so as to transfer the seat part from the use position to the at least one non-use position and back, wherein the seat kinematics has a rocker which by a first rotary joint is pivotably articulated on the base or an adapter that is fixedly connected to the base, and by a second rotary joint is pivotably articulated on the seat part. The invention moreover relates to a method for assembling a vehicle seat. BACKGROUND Known from DE 10 2008 050 468 B3 is a vehicle seat which is transferable from a use position, suitable for conveying a passenger, to a forward-pivoted non-use position, having a base; a rocker which is articulated on a front foot; a seat cushion which is articulated on the rocker and as a structure has a seat cushion support from the rear of which an arm projects, a joint being disposed on the end of the latter; a control arm which is articulated on the front foot; a rear foot that is articulated on the control arm and is able to be releasably locked to the base; and a backrest which by at least one lockable fitting is articulated on the rear foot so as to be pivotable about a backrest pivot axis and in terms of the rake thereof relative to the rear foot is adjustable; wherein the seat cushion by the joint is articulated on the backrest so as to be offset from the backrest pivot axis. DE 195 29 233 A1 discloses a vehicle seat, the vehicle seat having a seat part which is transferable from at least one use position, suitable for conveying a passenger, to at least one non-use position and back; a backrest; a base which is connectable to a vehicle floor; and a seat kinematics which for transferring the seat part from the use position to the at least one non-use position and back pivotably connects the seat part to the base, wherein the seat kinematics has a rocker which by a first rotary joint is pivotably articulated on an adapter that is fixedly connected to the base, and by a second rotary joint is pivotably articulated on the seat part, wherein a spacing between the base and the seat part disposed in the use position is infinitely variable. Known from DE 42 24 458 A1 is a seat cushion adjustment for vehicle seats, which is controlled as a function of a primary adjustment, wherein a separate adjustment mechanism which establishes the profile curve of the seat cushion adjustment within a limited adjustment range and has extreme positions that are assigned to the extreme orientations of at least one primary adjustment is provided, as a result of which it is avoided that defined external adjustment range limits of the seat cushion adjustment are exceeded. SUMMARY The invention is based on the object of improving a vehicle seat of the type mentioned at the outset. In particular, it should be possible for the vehicle seat to be adapted to different heights of vehicle floors while using simple means and maintaining a seat reference point. This object is achieved according to the invention by a vehicle seat, in particular motor vehicle seat, the vehicle seat having a seat part which is transferable from at least one use position, suitable for conveying a passenger, to at least one non-use position and back; a backrest, in particular a backrest articulated on the seat part; a base which is connectable to a vehicle floor, and a seat kinematics which pivotably connects the seat part to the base so as to transfer the seat part from the use position to the at least one non-use position and back, wherein the seat kinematics has a rocker which by a first rotary joint is pivotably articulated on the base or an adapter that is fixedly connected to the base, and by a second rotary joint is pivotably articulated on the seat part. A spacing between the base and the seat part disposed in the use position is variable by selecting a first articulation point for articulating the first rotary joint on the base or on the adapter that is fixedly connected to the base, and/or by selecting a second articulation point for articulating the second rotary joint on the seat part. As a result of the spacing between the base and the seat part disposed in the use position being variable by selecting a first articulation point (of at least two first articulation points) for articulating the first rotary joint on the base or on the adapter that is fixedly connected to the base, and/or by selecting a second articulation point (of at least two second articulation points) for articulating the second rotary joint on the seat part, the vehicle seat can be adapted to different vehicle floor heights while maint
