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.

Abstract: A seat for a stair lift, which seat is provided with a fall protection device comprising at least one elongate safety bar which is movable between an open position and a closed position, in which open position a person can freely move into and out of the seat, wherein the safety bar is movably connected to an elongate support that is stationarily connected to the seat, which support extends on a side of the seat, wherein the fall protection device is designed so that in the open position the safety bar takes up a rearward position, in which it extends substantially parallel to and beside the support, and that in the closed position the safety bar takes up a forwardly moved (along the support), inwardly pivoted or rotated position, in which it extends from the front end of the support, in which position it can be locked, such that a person cannot fall out of the seat.

Abstract: A device for conveying a person from a first to a second level, in particular a stair lift, which includes a rail (9) which extends between said first and said second level, a frame (3) which is designed to engage the rail in such a manner that it can be moved along the rail, and wherein the frame is configured to move along the rail, and a carrier (4) on which the person can seat himself, in particular a chair, wherein the device is further provided with a safety device which includes a central processing unit and a wireless communication network designed to communicate status information on components of the device and/or objects in the vicinity of the device to the central processing unit, and wherein the processing unit is designed for deciding, on the basis of the communicated status information, whether or not the frame is to be moved along the rail.

Abstract: A stair lift comprising a rail which is mounted along the staircase, at least partially at an angle to the horizontal plane, and a frame which is movable along the rail, on which a chair is mounted, which frame is provided with support and drive means that engage the rail, wherein the chair is rotatable about a vertical axis relative to the frame between two extreme rotated positions, wherein the chair comprises a seat on which a person can be seated and wherein the chair comprises a footrest on which a person seated on the seat can rest his or her feet, wherein the seat and the footrest are rotatable at mutually different angles about the vertical axis.

Abstract: A device, in particular a stair lift, for conveying a person from a first level to a second level, comprising a rail (2) which extends between the first and the second level, a frame (3) which is provided with engaging means designed to engage the rail (2) in such a manner that the frame (3) can be moved along the rail (2), driving means designed to cause the frame (3) to move along the rail (2), and a support (5), in particular a chair, on which the person can be seated, which stair lift is furthermore provided with control means designed to activate the driving means, wherein the control means comprise at least a touch-sensitive surface (9), which surface extends or may extend in such a manner that a person can rest his or her hand, or a part thereof, on the surface so as to activate the driving means.
