The sleeve is provided with a between the seat and the seat support. Releasable means are provided for locking the rotatable sleeve in a stored position or in a selected operating position or positions. When the locking means are in intermediate positions, the entire sleeve canbe lifted from the pedestal or vertical support. Further, means are provided for releasably locking the seat in both horizontal and vertical positions.

chair unit 20 is comprised of a swiveling seat unit 21 on an essentially Z-shaped pedestal 22, with an offset column 23 supported by a horizontal beam 24 attached to a floor base plate 25. i

As shown in FIG..16, the pedestal 22 consists of an inner column 26 enclosed by a cylinder 27 closed at the top 28.The cylinder 27 rotates or swivels on the inner column 26. l

The locking mechanism 29, as seen in FIGS. 14 and lS, consists of a knob 30 on a plunger 31, held in place by a spring 32 inside of a supporting housing 33 and nestles into a recess'34 in the .column 26 for locking it in the stored position, or recess 35 for locking it in the'operating position. When the locking 'mechanis m"2 isdisengaged and is swunganywhere between the recesses 34 and 35, the chair unit 20 may be raised off the inner column 26 and removed" from the vehicle. Y

A supporting ring 36 is welded to the plate 25 as well as theinner column 26v to form a strong union of the two. It also acts as a spacer with a carpeted floor so that the carpeting does not have to belaid under the lower end of the cylinder in orderto fit snugly against the column 26, which'would provide a possibility of the carpeting shredding and wadding up under the cylinder, or even between the cylinder andthe column, causing a binding action. 1 The seat unit 21 consists of a tubular steel frame 37 supporting a back cushion 38 and a seat cushion 39.

As shown in FIGS. 10, 14 or 15, the tubular steel seat frame consists of a U-shaped steel tube 40 with a rear stretcher tube 41 and a set of parallel tubes 42' and 43 on which the chair slides to obtain a fore and aft adjustment. I I

The tubular frame is supported by a top plate 44 and is attached to it with four clamps 45 to 48 by screws, lock washers, and nuts 49. u

The fore and aft adjustment mechanism50 consists of a knob 51, plunger 52, spring 53, supporting housing 54 attached to the underside of the U-tube 40, and an adjustment bracket 55. The plunger 52 engages with the adjustment bracket 55 by slipping I position,FlG'. 13. I

the flanged bearing 58 by a set screw 62 as well as an outer'cylinder 63 attached to thebeam 24. An assist spring 64 fits inside the cylinders, pushing against the bottom plate 65-and the swivel collar 59, to aid in raising the seat from the low position in F I6. 11 to thehigh position in FIG. 13. Inside the assist spring 64, there is an inner tube 66, closed at the upper end 67, to act as a stop, with the long bolt 68, to prevent the seat from accidentally being pulled off the offset column when raising the seat to the high As shown in FIGS. 5, 6 and 7, the height adjustment mechanism 69 consists of a knob 69a at the end of the operating rod 70 which itself is attached to the inner or guide cylinder 61'by a bracket 72, then is bent downward so that the up stop 700 at its lower end will engage with one of the several notches of the rack 73, attached to the outer cylinder or seat support 63. The up stop 70a is held in one of-the notches of the rack 73 by a spring 71 inside of the bracket 72 until the operating rod 70 is pulled up, forcing the up stop 700 out of the notch so that the seat may be raised or lowered. l

While in the foregoing specification we have shown the structure in considerable detail for'the purpose of illustrating an embodiment ofthe invention,-it will be understood that such details maybe varied widely by those skilled in the art without departing from the spirit of our-invention.

We claim:

x'refiiemtta'iaaarrattan' coniprisingi abasei aflvertical support column mounted to said base; a sleeve telescopically, and rotatably carried by said support; a laterallyrextending beam carried by said sleeve? a'nofiset tubular column supported by said beam and including vertically spaced notches; seat column and spaced inwardly thereof to define an annular spaceto receive said intermediate cylinder when said seat is lowered; campi' sian" sfifiiig 'means engaging said'means rotatably mounting said post to urge said intermediate cylinder and .said seat means upwardly; a rod connected to said post and received within said inner tube and including means. preventing complete retraction therefrom for limiting the upper extension of said seat; and an operating arm mounted to said intermediate cylinder abbve said offset cylinder including astop'engageable with a selected one of said notches and selectively movable-to a disengaged position permitting adjustment of the elevation of said seat means. 1

2. The structure of claim 1 wherein said seat means includes a horizontalplate mounted to the top of said post; a tubular seat frame supported bysaid top plate and including first and second tubular members extending fore-to-aft of said seatyclamp means securing said tubular frame members to said top plate while permitting longitudinal sliding motion thereof along said top plate; an apertured adjustment bracket mounted to said top plate beneath said frame: a spring- 3 biased plunger mounted beneath said seat framejand a baseplate: a vertical column attached to said base plate and including at least first and second recesses formed in the side thereof; and wherein said system further comprises locking mechanism rotatably and slidably mounted to said sleeve and including a retractable plunger biased against said-column and adapted to enter one of said recesses when aligned therewith; a beam-extending laterally of said sleeve; tioned either in an operating position or a stored position, and said sleeve may be removed from said column in any intermediate position. I

4.'The structure of claim 'l further comprising an annular supporting ring secured to said base column and to said base and serving as'a spacer with a carpeted floor.

5. A vehicle attendants chair base plate; an upright column mounted to-said-base plate and extending above the same, said column defining first and second recesses spaced at different angular locations thereabout; a sleeve rotatably mountedto said column; .locking mechanism rotatably 1 therewith; a beam extend ng laterally of said'sleeve;

plunger and turning said sleeve until said plunger.

aligns with one of said recesses and said seat and beam may be removed completely from said floor column by retraction of said plunger from either of said recesses; said seat including a downwardly-extending post slidably received within said guide-cylinder; a

top platemounted to the top of said post; a tubularseat frame carried by said top plate for-forward and aft'sliding motion; an adjustment means including a bracket attached to the underside of said side plate and including a plurality of laterally-spacedapertures; and a retractable plunger carried by'said seat frame for locking said frame relative to said top plate when said plunger is received in one of said apertures of said adjustment bracket while permitting fore and aft adjustment of said seat frame relativeto said top plate when said plunger is retracted from said apertures of said adjustment bracket.
