Abstract: A working chair comprising a seat member and a back member, each of which is pivotable about a horizontal shaft mounted in an underframe so that the seat and back members are individually adjustable, and a releasable locking means for fixing of the seat and back members in a set position. The locking means comprises a number of locking plates of which a first number of plates is fixed to the underframe at a distance behind the pivot axes of the seat and back members, and a second number of plates is fixed to the back member. The locking plates co-operate with a clamping unit mounted on the underside of the seat member and comprising clamping members for clamping the locking plates therebetween by spring action. Said spring action may be neutralized by means of a manually actuatable handle.

Abstract: A seat supported on a fixed pedestal with a mount assembly operable to permit rotational movement of the seat about an upright axis, longitudinal fore and aft movement and transverse tilt movement of the seat. The mount assembly has a base member pivotally connected to the pedestal for movement about an upright axis. A first lock pin locks the base member in a fixed forward position. When the lock pin is released the base member can rotate about a generally horizontal axis. A pair of longitudinally located track assemblies are pivotally connected to the rear portion of the base member. The forward portions of the track assemblies are held in selected elevated positions with releasable locking arms thereby changing the tilt position of the seat. The track assemblies also have movable carriages that can be locked in selected longitudinal positions to adjust the fore and aft position of the seat.

Abstract: A tilting unit for furiture, preferably for chairs, consists of two pivotably connected main parts, whereof one is attached to the chair foot or base and the other to the chair seat in order to allow limited tilting of the seat, the parts preferably being lockable together in a desired tilted position with the aid of handle operated locking means. Biassing means for yieldingly opposing tilting forces caused by the occupant comprise at least one block of resilient material located between opposing faces provided one on each of the unit parts.

Abstract: A chair control comprising a frame structure adapted to be supported on a conventional chair base, a chair seat support pivotally mounted on the frame structure for fore and aft tilting movement relative to the frame structure, a biasing structure such as a torsion bar biasing the seat support to a position corresponding to a normal seating position of a chair seat, and rotatable blocking members mounted on the seat support for movement, in a tilted position of the seat support, to a position engaged with the frame structure so as to block return movement of the seat support to the normal position. The blocking members are operable by an actuating knob conveniently located close to the seat for operation by the seat occupant and are moveable to a plurality of positions corresponding to various tilted positions of the chair.

Abstract: A carriage for carrying a baby or child is disclosed wherein a wheeled chassis has attached to it a body for carrying the child, the body being adjustable to facilitate various sizes of children. The body is adjustably attached to the chassis to readily move from a sitting to a horizontal position. The body also adjusts so as to accept a mattress for an infant and to form a seat for an older child.

Abstract: The automobile seat assembly is provided with a seat swingably mounted on the spaced longitudinal brackets. An assembly mounted on one of the brackets and adapted for adjusting the seat position includes a latch member pivoted to the seat and a detent fixed to the bracket. The latch member is provided with notches for engagement with the fixed detent and operatively connected to a manual handle lever. When the manual handle lever is operated, the latch member may be moved into and out of engagement with the fixed detent and rotated on the bracket so as to adjust the height of the seat position.

Abstract: A chair is rotatable and rockable, has an adjustable headrest and arm and leg rests selectively pivotable into use positions, and is carried for forward and backwards movement upon a baseplate attached at a forward end thereof to a work station fixture such as a desk or work table. The chair has an undercarriage with two rollers and a guide bar forming a "T." The base T is guided in longitudinal movement by a guide tube with which the guide bar is telescopic and by raised longitudinal edges along the base plate cooperating with the rollers of the undercarriage.

Abstract: An adjustable chair the structure of which features a supporting structure, a thigh supporting frame which is rigidly connected to the supporting structure, a buttocks support which is pivotally connected to the supporting structure, a back frame rigidly affixed to the buttocks support at an angle thereto, the buttocks support being adjustably connected to the thigh supporting frame by laterally spaced pivotal connections for adjusting the inclination of the buttocks support relative to the thigh supporting frame, a unitary, taut resilient covering which is disposed upon and interconnects with both the thigh supporting frame and buttocks support, said covering having cut out portions in the area of the buttocks support adjacent each pivotal connection and extending from the back frame to a portion of the thigh support frame adjacent each pivotal connection whereby when said buttocks support adjacent each pivotal connection and extending from the back frame to a portion of the thigh supporting frame adjacent e

Abstract: A unit of hardware for reclinably adjustable seating of vehicle driver and/or passenger and adapted to be swiveled into selected position, and comprising a pedestal rotatably receiving a socket positionably locked thereto, and a stop plate positionably locked in reclined positions by a toggle pin carried into tight engagement therewith by a manually releasable lever operated shackle, the tilt being positively restricted.

Abstract: A chair or wheelchair for infirm patients, principally comprising a frame for the support of a seat, a backrest, arm- and feet-supports, in which the seat is rotatably mounted in the frame, the backrest is rotatable in a plane at right angles to the seat and likewise can be moved parallel to the seat, the arm-supports can be slidably moved in two directions extending at right angles to each other, and the feet-support is rotatable around a hinge at the front side of the seat. The seat has a sleeve at its lateral sides provided with an ear to which a tap is fixed, which tap is supported in an upright post of the frame, whereas at the rearward side of the seat a plunger of a pneumatic spring is secured, the cylinder of which is rotatably mounted to the frame.

Abstract: A tiltable chair has a frictional resistance to tilting, and locking means releasably securing the erect position of the seat. Resistance to tilt preferably decreases with increased tilt angle, and is generated by the resilient engagement of bearing members acting against opposite surfaces for lateral neutralization of forces. The locking means is released in response to pressure on the chair seat.
