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.

Abstract: A device (1) for conveying a load from a first to a second level, in particular a stair lift (4), comprising a rail (3) and a frame (9) which is movable along said rail (3), on which a load carrier (10) is mounted and which is provided with support and guide means (16, 17, 33, 36) that engage around at least part of the rail (3), which rail (3) extends above steps of a staircase near a wall or a handrail on one side of the staircase, the rail (3) comprising a tube and a strip (6) that extends radially away from the tube surface, which strip (6) is engaged by the support and guide means (16, 17, 33, 36), whereby the strip (6) extends obliquely from the tube in a direction that extends between the horizontal direction toward the wall or the handrail and the vertical direction toward the steps.

Abstract: A computer program for the extraction of information about one or more spatial objects by a person, which program is designed for analyzing the sequence of images in real time, using image analysis techniques, and extracting information about said one or more objects, and communicating at least part of said information to the person in real time via the output means; wherein the information about said one or more objects comprises at least: the spatial position of said one or more objects; the spatial distance between two objects; the spatial relative angle between two essentially linear objects; and/or an indication regarding the realized accuracy of the extracted information.
