  • Patent number: 6742843
    Abstract: The present invention discloses an overload protection mechanism for a cable actuated feature on an office chair. The overload protection device allows a person seated in the chair to move a handle to actuate the particular feature of the chair, for example, a reclining backrest, even when the seated person's weight on the backrest prevents the backrest locking mechanism from engaging or disengaging. The movement of the handle causes the cable to move even when the locking mechanism connected to the opposite end of the cable is unable to engage or disengage. The mechanism stores the motion of the cable in a spring device connected to the movement actuators by a rack and pinion gear system. When the binding is released from the actuators, the mechanism moves as originally intended, motivated by the force of the decompressing springs.

The seat is supported in the front by opposite pins for a pivot motion of the seat cushion. A rotary cover plate is hinged at one end below the cushion and adapted to open an opening formed in the floor surface which permits the back portion of the seat to fall into the opening. The door is suported in a closed ordinary condition by means of a locking pin of a locking pin mechanism. The seat back is supported on the supports and hinged at the upper end and supported at the lower end by opposite lock pin members which when a collision occurs the pins release the seat so that the seat is hinged at its upper end.

  • Patent number: 5335964
    Abstract: A convertible child restrain seat is provided having a seat portion pivotally mounted to a base, the base including a spring biased slide bar having a post, the seat portion having an elongated member having a plurality of catches configured to mate with the post. Each catch corresponds with a different angle of inclination of the seat portion relative to the base. The post is thereby biased towards the catch to secure the seat portion at a selected angle of inclination. The angle can be adjusted by sliding the slide bar away from the catch and pivoting the seat portion between an upright position, a semi reclined position and an inclined position. An adjustable shield is also provided incorporating a cam actuated height adjustor to allow for shield position adjustment relative to the seat portion.

  • Patent number: 4773704
    Abstract: Apparatus for adjusting various parts of the seat in a motor vehicle has first and second adjustable units which receive motion from discrete first and second rotary driving elements in the form of gears or clutch sections. The driving elements flank an axially movable disc which has teeth or claws movable into engagement with the teeth or claws of the one or the other driving element in response to depression of a pushbutton which is surrounded by a hand wheel serving to rotate the selected driving element by way of a hollow shaft which non-rotatably carries the disc and surrounds an actuating member which transmits motion from the pushbutton to the disc. A locking device operates between the shaft and a pin which is reciprocable with the disc to releasably hold the disc in torque-transmitting engagement with the selected driving element.

    Abstract: An articulation in which a fixed iron member fixedly mounted with a seat frame comprises control means acting on an eccentric member causing upon rotation a locking and respectively an unlocking of a toothed center bearing plate. The toothed center bearing plate has such a shape that when it is pushed on the toothing of the iron member fixedly mounted with the seat frame, it is laterally blocked by reaction thus preventing any lateral displacement even if the mating cooperating toothings comprise some clearance. A rotation pin of the seat back with respect to the seat frame is so shaped that it is supported on two different points on an ovalized bearing member of the iron member fixedly mounted with the seat frame.

  • Patent number: 4384743
    Abstract: A contact surface on a toothed segment member which controls the recline position of a seat back is abutted by one or the other of a pair of contact surfaces on a stop element to limit the recline angle of the seat back. An off-center threaded opening in the stop element is adapted to receive a bolt passed through a selected one of a plurality of adjacent openings in a bracket on the seat frame. Thus, by turning the stop element over, it is possible to provide a number of discrete stop positions equal to double the number of adjacent openings in the bracket. Cooperating curved surfaces on the bracket and stop element having their center of curvature on the axis of the seat back support shaft assist in installation and ensure that the abutting contact surfaces can fully engage each other at any angle of adjustment.
