Abstract
A seat for a stair lift includes a horizontal seat, a vertical back rest, and two arm rests. Each arm rest is connected to the seat by a support bracket, and each arm rest is pivotable between folded-down and a folded-up positions. The arm rest is pivotably connected about a pivot axis to the support bracket and to a carrying beam having upper and lower sides. The upper side supports an arm of the sitting person. The arm rest is designed such that lower and upper tangents of the carrying beam extend at the same side of the pivot axis. The lower tangent is at a radial distance from the pivot axis, such that in the folded-up position the carrying beam extends from the vertical plane through the pivot axis in the vertical space behind the vertical plane towards and beyond the back side edge of the seat part.
