  • An adjustable seat adapted particularly for railway carriages and the like, comprising seat and seat-back combination having a dual connection to a fixed base structure, including, on one hand, towards the front and under the seat a sliding and swivelling connection of slideblock and slideguide and, on the other hand, towards the bottom and at the back of the seat-back a connection with tie-rods pivoting between a transverse spindle of the base structure and a transverse spindle of the seat and seat-back structure, further including an elastic member such as an extensible rubber cord, exerting a tractive force between the front of the seatback structure and the back of the fixed base structure, the dimensions and proportions of the seat and of the elastic member providing for an equilibrium balance of the seat in all of its adjusted positions 7 Claims, 11 Drawing Figures PATENIEU JANZ I IQYS SHEET 1 OF B PATENTEDJANZI I975 SHEET t [If
  • the present invention relates to an adjustable seat, particularly adapted for use in railroad cars. More particularly, the invention relates to a seat which may readily be adjusted by tipping a seat-and-back assembly of the seat in conformance with the dual movement of a slot which is formed beneath the front of the seat and of a tie-rod fastened at the rear of the seat back.
  • Tippable seats of generally this type have been described, in particular in French Pat. No. 823,912 with the purpose of reducing the frontage occupied by the seat, in effect, during adjustment, the top of the seat back moved almost vertically without disturbing any passenger who was seated behind that particular seat.
  • prior art seats were of comparatively heavy construction, considering the state of the art at that time, and during adjustment, with the seat being unlocked, the frictional forces were sufficient to prevent any involuntary tipping over.
  • a more particular object of the present invention lies in the provision of a seat which may be adjusted by tipping the entire seat-and-back assembly, thereby permitting a neutral or quasi-neutral balance equilibrium to be obtained for the whole seat-and-back-assemblyandoccupant combination irrespective of the weight of the occupant and of the adjusted position of the seat.
  • the invention is essentially predicated on the applicants determination that, by appropriately designing the dual front-slot and rear tie-rod connecting structure, a curve is obtained for the path of the center of gravity of the adjustable seat-and-occupant combination which at first is almost horizontal and then extends slightly downwardly, but at a slower rate of traverse. Furthermore, this path of the center of gravity may be effectively compensated for by the extension curve of an elastic means, such as a rubber cord, which is under initial tension acting as a tractive force between the seat front and the rear of its base structure.
  • an elastic means such as a rubber cord
  • the present invention eliminates the need for complex and expensive seat locking devices which are frequently required in order to maintain the adjustable seat in a particular adjusted position.
  • the adjustable seat which is particularly applicable for use in railroad cars, comprises a one-piece seat-and-back construction which incorporates a dual connection to a fixed base structure of the seat.
  • the connection includes, first, a forwardly and beneath the seat located swivable slideway connection formed by a slideblock and slider guide and, secondly a downwardly and behind the seat-back connection provided through tie-rods swivably supported between a transverse spindle of the base structure and a transverse spindle of the seat-and-back structure, with the connections according to the invention comprising firstly an elastic member, such as a rubber cord, exerting a tractive pull between the front of the said seatand-back structure and the rear of the fixed base structure and, secondly, predetermining the size and proportions of the seat and of the elastic means so as to assure the neutral equilibrium of the seat irrespective of its adjusted position or occupancy.
  • an elastic member such as a rubber cord
  • the elastic means operates by exerting a tractive force between, firstly, the front of the seat-and-back structure and, secondly, downwardly and behind the seat back, and with at least one lengthwise extension of the tie rods of the swivable tie-rod connection extending toward the transverse spindle of the base structure opposite the seat-and-back structure.
  • a further object of the invention is to provide a seat structure which permits the passenger to assume a position simultaneously upright and forwardly, suitable for dining requirements.
  • the adjustable seat is provided with, in addition to the slideblock and slider guide connection, at least one tie-rod connection which is pivotally mounted first at one end on a spindle integrally fastened to the seat back, and secondly at the other end on a movable slide located adjacent a ramp integrally fastened to the fixed seat base structure, including an elastic means, such as a spring, exerting a tractive force between the front of the seat-andback structure and an extension of the tie rod located toward the slide opposite the tie rod, and with the slide being able to assume, alongside the ramp, at least two regulated stationary positions, in effect, a far-back position and a forward position, pertaining which the predetermined size and proportions of the seat and of the elastic means assure their neutral equilibrium with respect to any seat-and-back-assembly-and-occupant combination irrespective of the adjusted positions of the combination.
  • an elastic means such as a spring
  • an object of the invention lies in providig maximum comfort for the passenger, while allowing him to adjust the position of his seat as desired without each time having to operate a locking device. Further, there are no longer problems as to any arrangements providing for a straight forward and simple translatory movement, such as those facilitating adjustment of a driver's with respect to a steering column of an automobile responsive to the driver's size.
