Abstract: The seat back unit has a seat back frame which can be tilted around the tilting axis (11) of the support (21). Movable on the seat back frame (13) is the seat back (25). A linear motor (33) serves to incline the seat back frame (13) together with the seat back (25). With a linear motor (33) the distance between the support (21) and the connecting section (17) of the back frame (13) can be reduced or increased, respectively. A tape (43) extends from a stationary part (45) of the linear motor (33) via the connecting section (17) to the seat back carrier (44). Accordingly, if the seat back frame (13) is tilted towards the rear, the seat back (25) is moved downward together with the arm rests (29) attached to the seat back carrier (44). A stabilizing mechanism (51) keeps the arm rest (29) in a practically horizontal position. Accordingly, on reclining the arms of the user remain always in a practically horizontal position and are finally lowered to a position practically parallel to the body.

Abstract: A retractable armrest is disclosed for a foldable chair. The chair has a seat and a backrest with the backrest being pivotably mounted to the seat by a chair pivot for movement between an operating position and a folded position. A link pivotably operates between armrest and the seat for enabling the armrest to be rotated into the retracted position when the backrest is in the operating position. The link rotates the armrest from the extended position to the retracted position upon the backrest being moved from the operating position to the folded position. The foldable chair is suitable for use on a personal mobility vehicle such as a scooter, a power wheel chair, a foldable personal mobility vehicle or any other suitable chair.

Abstract: An armrest retained a first pin that extends from a back member that is rotatable with respect to a base for a seat. A first lever located within the armrest defines a cantilevered beam with teeth thereon that mesh with teeth on a plate secured to the first pin. A second lever located on a second pin within the armrest positions a ball held in an opening therein in tangential engagement with the armrest and in contact engagement with the first lever. The second lever responds to an input force by pivoting on the second pin and apply a force through the ball to laterally move the teeth out of meshing engagement and permit the armrest to pivot on the first pin into a desired alignment with the base. On termination of the input force, the cantilever beam returns the teeth to meshing engagement to sustain the desired alignment.

Abstract: An ergonomic arm support system maintains a neutral position for the forearm. A mechanical support structure attached to a chair or other mounting structure supports the arms of a sitting or standing person. The system includes moving elements and tensioning elements to provide a dynamic balancing force against the forearms. The support structure is not fixed or locked in a rigid position, but is an active dynamic system that is maintained in equipoise by the continuous operation of the opposing forces. The support structure includes an armrest connected to a flexible linkage or articulated or pivoting assembly, which includes a tensioning element such as a spring. The pivoting assembly moves up and down, with the tensioning element providing the upward force that balances the downward force of the arm.

Abstract: A collapsible chair has a seat (102), rear leg (110), and an armrest (160), and further has a back support element (120) and a pair of lateral cross braces (130, 140). The back support element is pivotally coupled to the rear leg, and the lower end of the back support element is movably guided along one first cross brace by a guiding element (150), while the armrest is coupled to the upper end of the other cross brace. Preferred collapsible chairs include a footrest (180) that moves upward and forward, when the backrest reclines. A locking mechanism (170) provides for reclining of the back support among a continuous set of positions.

Abstract: The invention relates to a seat, especially a vehicle seat, and preferably an air passenger seat, comprising a seat element and a seat element carrier (12), a backrest (10) which can be adjusted in terms of the incline thereof, and at least one armrest (14), said armrest being pivotably joined to the backrest (10). The armrest (14) is continuously moved with the increasing or decreasing incline of the backrest (10) by means of an adjustment mechanism (20), said adjustment mechanism (20) for the armrest (14) comprising at least four articulation points (22, 24, 26, 28). A parallelogram articulation of the armrest is thus achieved by which means said armrest can lower itself. The aim of the invention is to be able to practically bring the backrest into a horizontal position in which the so-called parallelogram geometrically follows a fictitious line in an average incline position of the backrest, the four articulation points of the parallelogram lying on one line.
