Abstract: A foldable support base for a foldable furniture with a flexible user support platform, in which a support frame has two side frame members, each pivotally connected to a load pivot joint along a load member with a load section extending beyond the load pivot joint which is pivotable about the first load pivot joint towards a center of the support frame. The load sections of the load members are configured for removably attaching a flexible user support platform therebetween. A load on the flexible user support platform results in a force component pulling on the load sections of the load members to cause the load members to pivot about the respective load pivot joints in a direction towards the flexible user support platform, thereby biasing to keep the side frame members to be spaced apart to maintain the support base in an extended configuration.

Abstract: A chair includes a support frame, and a seat connected to the support frame. The seat is configured to support a user and move with respect to the support frame. The chair includes a back portion connected to the seat. The back portion is configured to move with respect to the seat. The chair includes a foot rest connected to the seat. The foot rest is configured to move with respect to the seat. The chair includes a lower strut connected between the back portion and the foot rest. The lower strut is configured to move with respect to the back portion. The lower strut is configured to move with respect to the seat.

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.

Abstract: Systems and methods for positioning the oral cavity of a dental patient are described. A method includes: providing: a pivotable chair with: a reclinable back; and a headrest connected to the reclinable back, the headrest including: a bracket for attaching the headrest to the reclinable back; and a pad connected to the bracket, the pad including an internal perimeter that defines a hole through which a prone patient's nose and mouth can protrude so that the prone patient's oral cavity can be reached from below the prone patient; locating the dental patient on the pivotable chair in a prone position so that the dental patient's nose and mouth protrude through the hole; pivoting the pivotable chair; and reaching into the dental patient's oral cavity from below the dental patient. The systems and methods provide advantages in that back and neck stress on the dentist is reduced while dental prophylaxis is facilitated.

Abstract: A chair-bed allows a person to sit comfortably and to stretch out in a recumbent position; it can be folded together to be flat and easily transported, provided that in the frame parts of the back rest (5), the seat (6) and the leg rest (7), the following conditions are fulfilled: a+b>c+d, e+f>g+h, where a is the distance between the points (11) and (3), b is the distance between the joints (3) and (10), c is the distance between the joints (10) and (8), d is the distance between the joints (8) and (11), e is the distance between the joints (23) and (22), f is the distance between the joints (11) and (9) and h is the distance between the joints (9) and (23).

Abstract: An arrangement of a wheelchair with a movable seat and leg rest and a bed equipped with transfer apparatus provided with rollers, a movable sheet and lift arms, for transporting a patient comfortably across the bed to a sitting position in the wheelchair.

Abstract: A transverse motion linkage for a patient support has a four-bar linkage connecting the seat of the support and the base for forward transverse motion upon simultaneous reclining of the backrest and lifting of the leg rest through action of a three-bar, motion-imparting linkage.

Abstract: There is provided an arm rest assembly for a chair or the like, including an arm rest member and a support member which are pivoted together. The arm rest member has a top surface and the support member terminates below the top surface and is pivoted thereto at a location slightly rearwardly of the forward end. These members define an angle which changes as the chair is adjusted, and the arm rest member includes stop means forwardly of the support member and below the top surface, the stop means being adapted to come into contact with the support member when the angle enlarges to a predetermined size less than 180.degree.. This prevents the arm rest and support members from reaching a dead center position, and avoids the risk that the user's finger will become trapped between the support member and the forward end of the arm rest member.
