Patent number: 7641217Abstract: A detachable mobile seat includes a first part connected to a motor; a second part attached to the seat; and two links, each connected to the first part, the second part, and a wheel. The links transfer movement of the first part to the wheels. The first part includes a shaft connected to the motor, and two nuts disposed around the shaft that have screw threads in opposite directions and move along the shaft in response to operation of the motor. Each link includes a first link connected to the second part and to the nut, and a second link connected to the nut and to the wheel. The end of each second link that is nearest the wheel is rotatably connected to a connecting arm that has a rotating bar that rotates the wheel in response to operation of the links.Type: GrantFiled: April 27, 2007Date of Patent: January 5, 2010Assignee: Hyundai Motor CompanyInventors: Yeon Sang Yoo, Ju Young Lee

Patent number: 7201451Abstract: A drive (35, 37) reversible to two active states for optional generation of a force of displacement effecting retraction or extension of a foot rest configuration (11) is provided in an aircraft seat. The seat has seat components such as backrest seat element (1), and leg rest (9) coupled to the front edge area (3) of the seat element and pivotable between a lowered non-use position and raised use position. A foot rest configuration (11) is mounted to be movable longitudinally on the leg rest (9) between a retracted position and an extended position to form an extension of the leg rest (9). The leg rest is coupled to drive (35, 37) which may be switched between an inactive state of rest and an active state generating a force for displacement of the foot rest configuration (11).Type: GrantFiled: February 17, 2005Date of Patent: April 10, 2007Assignee: Recaro Aircraft Seating GmbH & Co. KG.Inventor: Jurgen Baumann

Patent number: 6742206Abstract: A nurse robot has a stand and a supporting assembly. The supporting assembly is mounted on the stand and has a seat, a backrest, a leg plate, step plate, a first driving device and a second driving device. The seat is attached to the stand. The backrest is pivotally attached to one end of the seat plate. The leg plate is pivotally attached to the other end of the seat. The step plate is pivotally attached to the other end of the leg plate. The first driving device is attached to the seat to drive the backrest and the leg plate to pivotally rotate relative to the seat. The second driving device is attached to the leg plate to drive the step plate to pivotally rotate relative to the leg plate. Accordingly, a patient can conveniently move to any desired place without any other person's help.Type: GrantFiled: April 3, 2003Date of Patent: June 1, 2004Inventor: Tai-Kang Han

Patent number: 5882037Abstract: A plate- or shell-like plastic trim panel is provided with a convex structure configured such that, in the event of a horizontal compressive load running essentially in the longitudinal direction of the vehicle, the trim panel undergoes a controlled elastic and/or plastic deformation in the direction of the adjoining free space. This arrangement avoids risking injury to legs of a vehicle occupant resulting from uncontrolled bending or breaking of flat trim panels without such convex structure.Type: GrantFiled: February 28, 1997Date of Patent: March 16, 1999Assignee: Mercedes-Benz AGInventors: George Bauer, Alban Bossenmaier, Santiago Duenas Loza, Friedrich Reiter

Patent number: 5845961Abstract: An improved dual leg rest assembly is disclosed which is adapted for use in single and multi-person articles of furniture (i.e., chairs, sectionals, sofas, loveseats, etc.). More particularly, an improved linkage mechanism is provided for causing coordinated articulating movement of a primary leg rest panel and a secondary leg rest panel (i.e., mid-ottoman) which as disclosed, also includes a selectable height ottoman.Type: GrantFiled: June 7, 1996Date of Patent: December 8, 1998Assignee: La-Z-Boy IncorporatedInventors: Larry P. LaPointe, Jonathan R. Saul, Karl J. Komorowski

Patent number: 5354116Abstract: A reclining chair is provided with an ottoman (or leg rest) which includes primary (or main) and secondary (or mid or middle) ottoman members separately mounted to pantographic linkage subsystems of the side linkages of the chair-operating mechanism. Both ottoman members are padded and include side skirts for veiling respective portions of the side linkages when the ottoman is in a raised condition. The secondary ottoman is articulated directly to the primary ottoman, for control, so that as the ottoman is being retracted to a stowed position below the front of the seat, the secondary ottoman is rotated from a face-upwards, to a face-rearwards orientation, and received into a pocket formed behind the primary ottoman, which is rotated from a face-upwards, to a face-forwards orientation.Type: GrantFiled: October 1, 1992Date of Patent: October 11, 1994Assignee: The Lane Company, Inc.Inventors: Teddy J. May, Walter C. Rogers

Patent number: 5038877Abstract: A vehicle instrument panel is disclosed with counter resetting knob, comping a push knob for resetting a trip recorder and mounted for sliding through a raised portion and a window. The knob comprises an end-piece with radial fins whose widened ends are situated between the raised portion and the window. Under the action of a compression spring the widened ends of the fins are urged towards the window, thus eliminating any play between the hole in the window and the end-piece.Type: GrantFiled: April 27, 1990Date of Patent: August 13, 1991Assignee: Societe d'Applications Generales d'Electricite et de Mecanique SagemInventor: Georges Dubuisson

Patent number: 4408796Abstract: The legrest projecting/retracting linkages of a recliner chair mechanism are designed to progressively provide pivotability for the legrest as the legrest nears its fully projected condition, i.e. is about three-quarters or more of the way out, and to progressively inhibit that pivotability in the initial stage of retraction of the legrest from its fully projected condition, i.e. in the first-quarter of its retraction. This may be accomplished without reworking the remainder of most existing recliner chair mechanisms. A number of ways that the legrest projecting/retracting linkages can be configured to achieve this objective are disclosed.Type: GrantFiled: December 29, 1980Date of Patent: October 11, 1983Assignee: The Lane Company, Inc.Inventor: Ned W. Mizelle

Patent number: 3964786Abstract: The specification discloses a wheelchair in which the seat, back and leg portions are so articulated and separately actuable, by power means, under control of the occupant, as to enable the occupant to assume any one of three positions, namely sitting, standing or reclining. Two separated leg support members are selectively actuable by the occupant to a horizontal leg-supporting position. Steering and forward and reverse propulsion controls accessible to the occupant are also provided, enabling the occupant to obtain substantially total mobility on level ground.Type: GrantFiled: December 20, 1974Date of Patent: June 22, 1976Inventor: David Mashuda
