Definitions
- ABSTRACT A seat has individual supports for the lower thigh of the user which are pivotally mounted at the front of the seat portion of the seat (i.e., the portion on which the user sits and which bears his weight). They are able to be individually depressed against a springloading by the user applying weight to them. The depression occurs in a pivoting motion about a pivot axis adjacent the upper surface of the seat portion but the path of this motion is defined by a linkage beneath the thigh supports and the seat portion, and there is no hinge at the pivot axis. The limit uppermost position of the supports, to which they are urged by the springloading, is controllable and two mechanisms are shown for this.
- An object of the invention is to provide an aircrew seat where movable support is given to the lower part of the thigh of a crew member using the seat without discomfort to the user, without need to adjust his sitting position as the support means and without substantial sacrifice of his freedom of movement.
- a seat having separate upholstered thigh support portions on each side of the front of the seat portion of the seat, each of which is individually resiliently loaded upwardly towards a support portion but is individually movable downwardly in an arcuate motion on pressure applied to it from above, being constrained to execute that arcuate motion about a pivot axis lying adjacent to the upper surface of the seat portion, without a pivotal hinge being provided at that axis.
- seat portion refers to the essentially horizontal part on which the user sits and by which he is vertically supported.
- FIG. 1 is a perspective view of an embodiment as an aircrew seat
- FIG. 2 is a plan view of the mechanism of the thigh support portion of the embodiment
- FIG. 3 is a sectional view on the line III-III of FIG. 2 with the thigh support of the embodiment in an uppermost position
- FIG. 4 is a sectional view similar to that of FIG. 3 but with the thigh support portion of the embodiment in a lowermost position
- FIG. 5 is a sectional view on the lines VV of FIG.
- FIG. 6 is a view similar to that in FIG. 3 but showing a modified embodiment
- FIG. 7 is an underneath plan of the modified embodiment, certain parts being removed for clarity.
- FIG. 1 there is generally indicated an aircrew seat 1 having a seat portion 2 with at each side of its front end, thigh support portions 4. These are separated so as to offer a channel 5 between them to receive the control column of the aircraft.
- each thigh support portion 4 is separately depressible when pressure is exerted on it from above, in an arcuate movement of which the axis is at the front of and adjacent the upper surface of the seat portion.
- the two thigh support portions 4 are mirror images of each other and only one will be described.
- Each side frame 6 of the seat portion is of box section and on the mutually outermost faces of the extreme front portion have secured to them slideways 7. Studs 8 at the ends of struts 9 which are fixedly secured to a tray under the upholstery 10 of the thigh support portion 4, are slidable along the slideways. At its front end each slideway is closed by a bridge 11 so as to provide a stop against movement of the studs 8 in that direction.
- each strut 9 Pivoted to each strut 9 is an arm 12 which is fixed at its lower end to a shaft 13 common to both arms 12 of the one thigh support portion 4.
- the shaft 13 is journalled in the side frame 6.
- the upholstery of the seat portion is brought to a shallow neck where the axis 14 is positioned and a void is left beneath that neck, which void defines a reentrant which in the illustrated embodiment is essentially prism-shaped as seen at 15 in FIG. 3, when the thigh support is in its upward position.
- This void is thus of a shape that its sides are substantially closed together, as shown in FIG. 4, when the thigh support is lowered.
- lever arms are fast with the shaft 13 and are joined by connecting rods 21 pivotally to essentially triangular double members 22 which are pivoted at 23 to the respective members of the side frame 6.
- the point of attachment to the rod 21 is remote from the pivot axis 23 as is also an anchor shaft 24, common between the plates 22 (and not shown in FIG. 2), to which is hooked a rubber band tension spring 25 which passes round a pulley 26 in a trunnion 27 attached to a cross member between the side members of the frame 6.
- the shaft 24 has a spacer sleeve to keep the hooks 37 of the tension spring spaced axially apart as is best seen in FIG. 5.
- the action of the spring 25 is to urge the members 22 rearwardly (to the right as seen in the FIGURES) hence to tend to rotate the shaft 13 and the arms 12 counter-clockwise thereby to restore the thigh support to its uppermost position.
- a shaft 30 is fast between the double members 22, approximately half way between the pivot point 23 and the shaft 24.
- a scissor linkage 31 of which each element is a pair of parallel fingers is controlled by left and right hand threaded nuts 32 running on oppositely threaded sleeves 36 rotated by a control shaft 33.
- the control shaft 33 is common to both thigh supports and has at one end a control wheel 35. The parallel fingers fit one above and one below the shaft 30.
- FIGS. 6 and 7 A modified mechanism for spring-loading the thigh support portions and controlling their uppermost positions is shown in FIGS. 6 and 7.
- Upward spring-loading is applied to the thigh support portion (only its base tray is shown in these FIGURES the upholstery is exactly as in the earlier FIGURES) by keying a single lever arm 20 to the shaft 13 which is in turn fixed to the arms 12 pivoted to the struts 9.
- This lever arm 20' is biassed upwardly by a rubber band spring 25 anchored by its hooks 37' to the respective side walls of the side frame 6, and passing round a trunnion pulley 27'.
- This has a stern which passes through a short shaft 38 housed rotatably in a split in the free end of the lever arm 20'. This bias urges the arms 12 forward, having the effect of biassing the thigh support portion upwardly.
- a control shaft 33' having a control knob as in the first-described mechanism is fitted with a bevel gear 40 which drives a smaller such gear 41 which is fixed to a shaft journalled in a pivotable cross-member 39 of the side frame 6, and having a screw-threaded portion 42.
- This tubular part is mounted pivotally at 47 between a pair of lugs 48 on the undersurface of the base tray of the thigh support portion.
- a pin 44 projects from the nut 43 on two sides and engages in the opposed guide slots 45.
- An upholstered seat comprising: a main seat portion having upper and lower surfaces, a forward end and individual thigh support portions each of which includes an upper and lower surface, biasing means individually and resiliently urging each of said thigh support portions upwardly into an upper support position, each of said thigh support portions being independently movable with respect to the other, said individual thigh support portions being located in juxtaposition with the forward end of said main seat portion at opposite sides thereof, individual strut means in fixed relation with each of said thigh support portions and extending downwardly therefrom and including guide pins, 21 frame member in fixed relation with said main seat portion, said frame member including a pair of elongate slots in which said guide pins are slidably received, a linkage assembly operatively connecting said biasing means to the thigh support portion associated therewith, said linkage assembly including a pivotally mounted lever means having one end mounted to one of said strut means and another end to a connecting link which is in turn operatively connected to said biasing means, said linkage assembly being disposed
- a seat as defined in claim 2 wherein the upper surface of the upholstery is smooth and uninterrupted adjacent the pivot axis, and the lower surface of the upholstery is interrupted by a reentrant when the thigh support portion is upward, the pivot axis being in a narrow neck of upholstery between the front of the seat portion and the thigh support portion.
- said adjustable limit means comprises a scissors linkage movable into respective open and closed positions, one pair of arms of said scissors linkage being operatively interconnected with said pivotally mounted connecting member to provide a stop means for said linkage assembly in one of said open or closed positions, and the opposed pairs of arms of said scissors linkage being screwthreadedly engaged in an oppositely screw-threaded fixed control axis, whereby rotation ofa control rod operates to regulate the extent to which said scissors linkage can travel in the fully open and fully closed positions associated with the particular setting of the control rod to thereby selectively control the action of said stop means on the linkage assembly.
- said adjustable limit means comprises a freely movable link, one end of which is mounted to one of said individual thigh support portions and the other end of which is con nected to said main seat portion, downward depression of the thigh support portion associated therewith being in opposition to the resilient loading provided by said biasing means and being in the direction of free move ment of said movable link, said link including an adjustable stop means for selectively determining the position from which said movement starts, whereby the uppermost position of the thigh support portion associated therewith can be selectively regulated.
- a seat having a main seat portion fixed relative to pivotally adjustable and depressible individual thigh support portions and having an upper surface for receiving and supporting vertically a user of the seat, the improvement comprising biasing means urging each of said thigh support portions into an upper support position, said thigh support portions including individual strut means in fixed relationship therewith and extend ing downwardly therefrom, said main seat portion including a frame member in fixed relationship therewith, and constraining means associated with each of said strut means and frame member, said constraining means including a guide pin which is slidably received within an elongate slot, one of said guide pin and elongate slot being in fixed relationship to said strut means and the other being in fixed relationship to said frame, a linkage assembly operatively connecting said biasing means to the thigh support portions associated therewith, said linkage assembly being disposed below said main seat and thigh support portions and including a pivotally mounted lever means having one end mounted to one of said strut means and another end fixed to a connecting link which in
