Abstract: Thin, Narrow vehicles have a single front seat, the driver seat, and as a result are at least 25% narrower than current four-wheel vehicles that have two front seats. Average US car occupancy rate is approximately 1.55 persons per vehicle mile, so narrow vehicles, comprising a non-adjustable width that is less than fifty-eight inches, a driver seat, and two seats in each back row, would provide increased seating options. As a result of the reduced width and reduced weight of narrow four or more-wheel highway vehicles, the vehicle performance increases, and production costs, traffic congestions, parking unavailability, fuel consumption, and CO2 emissions are reduced relative to a four-wheel highway vehicle. Because of their reduced width, narrow vehicles allow for lateral room to incorporate two jet engines on the lateral sides, and wings that extend and retract laterally from the roof and/or the floor, to create jet aircraft vehicles.

Abstract: The invention relates to a link chain having two rows of chain elements wherein the chain elements of one row are rotatably connected to those of the adjacent row in the chain plane in such a way that each chain element has two rotational axes, of which each one of the two rotational axes of two different chain elements is in adjacent rows, and that the chain elements of one row are connected to one another by means of toothings of their ends in such a way that the chain is flexible in the chain plane, wherein the rotational axes are designed such that the chain remains in a set position.

Abstract: A furniture member mechanism includes a first actuator device electrically operated to displace first and second seat back actuation links connected to and operating to rotate a seat back member between upright and fully reclined positions. A pantograph linkage set connected to a leg rest member is at least partially supported in an extended position by rotational contact with a support rod. A second actuator device identical to the first actuator device is electrically operated to axially rotate a drive rod connected to a drive link. The drive link is connected to and displaces the pantograph linkage set between the stowed and extended positions. A swing lever rotatably connected to the support rod is rotated during operation of the second actuator device to extend the pantograph linkage set. The swing lever in a fully rotated position displaces the support rod creating a furniture member tilt position.

Abstract: A four-bar linkage system for a chair having a leg rest extension, the linkage system having a first set of linkage members of irregular geometric shapes connected at one end to an outboard portion of a leg extension platform and at a second end to a seat member. A second set of linkage members of irregular geometric shapes is connected to the first set of linkage members and at one end to an inboard portion of the leg rest platform and at a second end to the seat member.

Abstract: A dock swivel step is attached to a dock pole by clamps. The swivel step has vertical outer and inner tubes. The vertical tube is clamped to the dock pole. An inner L shaped tube slides inside the outer tube. Attached to the horizontal part of the inner tube is an outer tube. The outer tube is attached to a bracket which in turn is attached to the dock step. The step is biases away from the dock and has a slot near the dock side of the step. The inner vertical and horizontal tube has an angle bracket which receives the slot the dock step to secure it in the horizontal and deployed position. In order to remove the dock step, one simply pulls the step slot away from the angle and pulls the step in the vertical position. The inner tube can then be rotated to a position where the step is vertical and parallel to the dock and in an un-deployed position.

Abstract: A chair has a seat connected to the seat support (1) by means of a front guide rod (11). The seat includes front and rear seat portion (8) hinged to each other. The rear seat portion (8) is secured to the seat support (1) by means of a rigidly connected downwardly extending element to which one end of a second guide rod (16) is hinged by a bearing (17). The other end of the second guide rod is connected by another bearing (15) to a section (14) of the back rest support (3). The back rest support is hinged at the seat support (1). A force storage member (13) is connected by joints to both the seat support (1) and to the seat.

Abstract: A dental chair operating apparatus developed in relation to the underseat and the backrest. The uses for the present chair and integral underseat and backrest configuration include human dental, medical, beauty parlor, and barber shop treatment facilities and installations. The present chair, e.g. a dental chair, is one with a hip section of the underseat baseboard on top of a vertical motion apparatus on top of a base plate; a movable circular arc board with backrest baseboard tilts by an oil-pressured cylinder. The present chair configuration is basically automatic, however it may also be manually manipulated.

Abstract: A wheelchair includes a main frame supported on front and rear pairs of wheels, the main frame pivotally mounting pivotally interconnected back rest, seat and leg rest frame segments in such manner as to allow said segments to be adjusted between positions supporting a patient in upright sitting position and in fully reclining position, without the necessity of first removing or otherwise requiring physical participation of the patient.
