| Abstract | A seat for a motor vehicle includes a backrest part with a front side and rear side facing away from the front side. A backrest surface, which serves for supporting a back, is transversely divided into a central section and two lateral sections. A seat part includes a sliding mount for the backrest part to realize a translational motion of the backrest part relative to the seat part between a forward facing position and a rearward facing position. Two lateral sections form a lateral support for a person on the seat and/or the seat part as a two-piece seat part including a first section and a second section and an intermediate space. A bracket extends through the intermediate space. |

| Claim | A seat for a motor vehicle comprising: a backrest part having a front side, a back side facing away from the front side, and a backrest surface configured to support a back of a seated occupant, wherein the backrest surface is transversely divided into a central section and two lateral sections; a seat part having a seating surface configured to support a buttock of the seated occupant; a sliding mount for the backrest part and configured to realize a translational motion of the backrest part relative to the seat part such that the backrest part is positioned in the region of a rear edge of the seat part in a first translational position and in the region of a front edge of the seat part in a second translational position; and a support provided on the seat having two lateral sections forming a lateral support for the seated occupant; wherein the two lateral sections, when in the first translational position, are spaced apart from the front edge of the seat part by a shorter distance than the central section in a horizontal longitudinal direction; wherein the two lateral sections, when in the second translational position, are spaced apart from the rear edge of the seat part by a shorter distance than the central section in the horizontal longitudinal direction; and wherein the sliding mount comprises a stationary rack and a rotatably mounted gearwheel having teeth which mesh with teeth on the rack such that a translational motion of the backrest part causes a rotational motion of the gearwheel such that the backrest part is pivotable about the pivoting axis with the pivot mount by a torque transmitted from the gearwheel to the backrest part. The seat according to claim 1 , wherein the support comprises a pivot mount configured to pivotably mount the backrest part about a pivoting axis such that the front side of the backrest part serves as backrest surface in the first translational position and a first pivoting angle position of the backrest part and the front side of the backrest part also serves as backrest surface in the second translational position and a second pivoting angle position of the backrest part. The seat according to claim 2 , wherein the pivoting axis is essentially aligned in the vertical direction. The seat according to claim 3 , wherein the pivoting axis is essentially arranged centrally on the backrest part. The seat according to claim 1 , wherein the support comprises a mechanism configured to pivot the two lateral sections relative to the central section and installed into the backrest part such that the front side of the backrest part serves as backrest surface in the first translational position and the two lateral sections are in a first pivoting angle position relative to the central section and the rear side of the backrest part serves as backrest surface in the second translational position and the two lateral sections are in a second pivoting angle position relative to the central section. The seat according to claim 5 , wherein the first and second pivoting angle positions are aligned relative to one another at a differential angle of essentially 180°. The seat according to claim 5 , wherein the first lateral section is pivotably mounted about a first lateral pivoting axis and the second lateral section is pivotably mounted about a second lateral pivoting axis, wherein the first and second lateral pivoting axes are essentially aligned vertically. The seat according to claim 7 , wherein the distance between the first and second lateral pivoting axes in the transverse direction essentially corresponds to the width of the central section. The seat according to claim 8 , wherein the rotating direction of the first lateral section for pivoting the first lateral section from the first pivoting angle position into the second pivoting angle position extends opposite to the rotating direction of the second lateral section for pivoting the second lateral section from the first pivoting angle position into the second pivoting angle position. The seat according to claim 5 wherein the translational motion of the backrest part causes the rotational motion of the gearwheel such that the two lateral sections are pivotable relative to the central section by the mechanism. The seat according to claim 10 , further comprising an actuator configured to move the backrest part between the first and the second translational positions. The seat according to claim 11 , wherein the actuator is configured to pivot the backrest part about a pivoting axis. The seat according to claim 11 , wherein the actuator is configured to pivot the two lateral sections relative to the central section by the mechanism. A seat for a motor vehicle comprising: a backrest part having a front side, a back side facing away from the front side, and a backrest surface configured to support a back of a seated occupant, wherein the backrest surface is transversely divided into a central section and two lateral sections; a seat part having a seating surface configured to support a buttock of the seated occupant; a sliding mount for the backrest part and configured to realize a translational motion of the backrest part relative to the seat part such that the backrest part is positioned in the region of a rear edge of the seat part in a first translational position and in the region of a front edge of the seat part in a second translational position; and a support provided on the seat having two lateral sections forming a lateral support for the seated occupant; wherein the two lateral sections, when in the first translational position, are spaced apart from the front edge of the seat part by a shorter distance than the central section in a horizontal longitudinal direction; and wherein the two lateral sections, when in the second translational position, are spaced apart from the rear edge of the seat part by a shorter distance than the central section in the horizontal longitudinal direction, the seat part comprises a two-piece seat part having a first section, a second section and an intermediate space between the first and second sections having a bracket extending therethrough, and the sliding mount comprises the bracket. The seat according to claim 14 , wherein the intermediate space comprises a slot extending in the longitudinal direction. The seat according to claim 14 , wherein the sliding mount comprises a rail and the bracket is movably mounted on the rail in the longitudinal direction by a bearing element. A motor vehicle, comprising: a vehicle body; at least one propulsion engine; and at least one seat including: a backrest part having a front side, a back side facing away from the front side, and a backrest surface configured to support a back of a seated occupant, wherein the backrest surface is transversely divided into a central section and two lateral sections; a seat part having a seating surface configured to support a buttock of the seated occupant; a sliding mount for the backrest part and configured to realize a translational motion of the backrest part relative to the seat part such that the backrest part is positioned in the region of a rear edge of the seat part in a first translational position and in the region of a front edge of the seat part in a second translational position; and a support provided on the seat having two lateral sections forming a lateral support for the seated occupant; wherein the two lateral sections, when in the first translational position, are spaced apart from the front edge of the seat part by a shorter distance than the central section in a horizontal longitudinal direction; wherein the two lateral sections, when in the second translational position, are spaced apart from the rear edge of the seat part by a shorter distance than the central section in the horizontal longitudinal direction; and wherein the sliding mount comprises a stationary rack and a rotatably mounted gearwheel having teeth which mesh with teeth on the rack such that a translational motion of the backrest part causes a rotational motion of the gearwheel such that the backrest part is pivotable about the pivoting axis with the pivot mount by a torque transmitted from the gearwheel to the backrest part. |
