ABSTRACT:
A sprung vehicle seat comprises a scissor support assembly formed by scissor members pivotable about a common pivot axis, and a gas spring for adjustment of the support assembly. A first valve device can be connected to the gas spring for adjustment of the height of the seat and a second valve device can be connected to the gas spring by way of a coupling for adjusting the height of the seat in dependence on weight. The coupling comprises a segment member which is pivotable about the support assembly pivot axis and which has an arcuate toothed portion, and a pivot arm with a tooth arrangement which can be brought into meshing engagement with the toothed portion. The pivot arm is connected to one of the scissor members of the support assembly and is actuable by a drive means connected to the first valve device. Also arranged pivotably at the support assembly pivot axis is a rocker member operable to actuate the second valve device and movable limitedly relative to the segment member.
