• GB 470702 - vaughan - discloses a swinging settee in which the seat and back support are suspended from a stationary frame by means of parallel links at each end.
• the frame also incorporates cross-rods which extend between the sides of the seat and a central longitudinal
• a chair comprising a stationary frame, a seat frame and a support wherein the support is pivotally connected to the stationary frame and the seat frame is pivotally connected to one end of the support so as to be capable of reciprocating movement relative to the stationary frame and further comprises armrests pivotally connected to a second end of the support, said armrests being capable of reciprocating movement relative to the stationary frame in the respective opposite direction to the seat frame.
• the support comprises at least two elongate elements which are pivotally mounted to the stationary frame.
• the support comprises at least one elongate element disposed on either side of the seat frame.
• the support comprises two elongate elements disposed on either side of the seat frame.
• the support is accommodated within the stationary frame.
• the elongate elements are joined to the stationary frame, the seat frame and the armrests by free moving but rigid bearings such as black nylon, metal, metal/inorganic materials or ball bearings.
• the armrests extend beyond the seat front edge and are suitably shaped so as to assist people getting in and out of the chair.
• the front pair of elongate elements can extend above the normal horizontal line of the armrests, or the armrests may be hinged near the front so that they can be raised from the horizontal to the vertical and locked in this position, so that the person sitting in the chair can obtain greater leverage to assist them in getting in and/or out of the chair.
• the support is provided with a locking means to fix the seat element and armrests in a given position.
• the tilt of the seat back is adjustable.
• the depth of the seat within the stationary frame is adjustable.

• Figure 3 is an end view of a linkage of a preferred embodiment
• Figure 4 is an end view of a second preferred embodiment of the invention.
• FIG 5 is a side elevation of the second preferred embodiment shown in Figure 4.
• the chair 10 shown in the drawings comprises a stationary part and a movable part.
• the stationary part comprises a frame 14 having four leg -members 15.
• the movable part comprises a swing-support 18, a seat element 20, and armrests 22.
• the seat element 20 includes a seat cushion 34, seat back 21 and a seat frame 12.
• the support 18 is arranged within the frame 14 and includes two pairs of elongate elements 24.
• the elements of each pair are in parallel, spaced apart arrangement, and one pair is arranged on either side of the inside of the frame 14.
• Each element 24 is pivotally connected to the main frame structure 14 at a point 17 close to, but spaced apart from its upper end 28.
• each element 24 is pivotally connected to a lug 19, projecting downwardly from the frame 14.
• each element 24 is pivotally connected to the frame 14 directly at a point 23.
• Each element 24 is also pivotally connected at a first lower end 26 to the seat frame 12 and at a second, upper end 28 to an armrest 22.
• the seat element 20 and armrests 22 are thus suspended within the frame 14 by two pairs of parallel, or substantially parallel, elements 24 and are capable of swinging backwards and forwards.
• the arrangement of the parallel elements allows the seat element 20 and armrests 22 to remain horizontal, or substantially horizontal, as they swing.
• the distance from the upper pivot point 28 to the central pivot 17 is substantially less than the distance from the lower pivot point 26 to the central pivot 17. This gives commensurately greater movement of the seat element 20 than the armrests 22.
• the frame 14 and support 18 are sufficiently rigid to keep to a minimum any lateral or torsional movement.
• the armrests 22 are suitably shaped to assist people getting in and out of the chair.
• the embodiment shown in Figures 1 and 2 includes an arrangement to check sideways movement which consists of one or more rollers 29 on each side mounted on the seat frame 12 running against horizontal guides 30 mounted on the frame 14.
• the guides 30 may also contain adjustable end stops 31 to arrest excessive forward and backward movement.
• the pivotal linkages between the elongate elements 24 and the frame 14, the elongate elements 24 and the seat frame 12 and the elongate elements 24 and the armrests 22 are black nylon, bronze or similar long-life bearings.
• the support 18 is concealed within the chair upholstery by panels 32 and 33 so that the chair is not obviously different from a conventional chair.
• a person sitting down in the chair can use the armrests on each side to steady themselves and the seat.
• the chair seat may be moved forwards to assist both sitting down and getting up by holding the chair body stationary.
• the swinging motion may be initiated and increased by pushing backwards and forwards gently on the armrests so that the seat and back will swing forward whilst the arms will swing back to a lesser degree and vice versa.
