Definitions
- Cushion for anatomical support especially for the lumbar and cervical regions, to fit onto seat backs.
- the invention concerns a small cushion designed for anato ⁇ mical support especially to the lumbar and cervical regions, to be mounted onto the backs of seats.
- Such small cushions are well known and are placed inside the seat backs of motor vehicles, their thickness and there ⁇ fore projection being variable to suit the needs or preferen ⁇ ces of the user .
- These cushions are made by means of a device comprising a rigid structure associated to an elastic structure. Convexity of the elastic structure in relation to the rigid structure may be obtained by a system of cams with a tie rod. The cam is operated from outside the seat by means of a mech- anism comprising a gear wheel and worm screw and a transmis ⁇ sion shaft worked by an external knob.
- the external structure consists of longitudinal metal bands crossing over transversal bands with outwardly projecting ends to ensure adequate spring.
- This device is very complex and its outer surface is rough and sharp. It has therefore to be covered with a soft layer of considerable thickness.
- the tie rod referred to above is involved in the curving movement of the elastic structure so that much effort is required to work the cam.
- the worm screw is inserted to lessen effort when the device is adjusted but the knob has therefore to be given a great many turns making adjustment time far too long.
- the device cannot be moved vertically from the lumber to the cervical region or in between, or adapted to the stature, needs and preferences of the user.
- Subject of the present invention is a small* cushion, to sup ⁇ port the lumber-cervical regions of the back, of greatly simplified structure and operation, that can be used on the outside of the seat and moved up and down to suit the user.
- the cushion consists of a curved elastic plate whose longitudinal ends are connected poster ⁇ iorly by a centrally placed vertical brace.
- Said brace is formed of a pair of aligned rods, threaded in opposite directions, that screw into an intermediate cylin ⁇ drical scroll .
- Convexity of said plate, and consequently thickness of the cushion and the extent to which it projects out from the surface of the seat back, can therefore be increased or lessened as desired by rotating the scroll one wa or the other .
- the cushion is placed externally to the seat back while the outer surface of the scroll is knurled and can be turned by the fingers from the outside through a specially made aperture in the outer covering of the seat back.
- the plate is placed inside the seat back.
- the scroll is connected to a transversal shaft .project ing from the side of the seat back, by a bevel gear and a uni- versal joint .
- a knob is fixed to the shaft for adjusting plate convexity from the outside.
- the plate slides on vertical run- ners fixed to the frame of the seat back and its height inside the seat back is determined by a continuous cord fixed centrally between the two longitudinal' ends of the plate .
- said cord After passing over transmission rollers mounted at top and bottom of the seat back and rolling freely, said cord winds onto the drum of a small transversal shaft, supported by the seat back, projecting from the side of said seat back and terminating in a knob for purposes of adjustment.
- the scroll is connected to thesmall transversal shaft and knob by means of a double universal joint connected by an intermediate shaft. It is an advantage to have said connecting shaft made in two pieces both axially free but rotating together.
- at the back of the cushion there are strips of Velcro-type material to make it cling at the desired height to a seat back covering of a suit- able kind.
- a cushion for anatomi ⁇ cal support is obtained adjustable not only in thickness and therefore in its projection from the seat back, but also in height to give support, as desired, to the lumber, cervical or other regions of the back as preferred by the user .
- the subject cushion can be applied either to the outside or inside of practically all kinds of seat backs. It can be used in particular for office seats or armchairs, for seats in cinemas, conference rooms or stadiums, for seat ⁇ ing in coaches, aeroplanes or motor vehicles, for means of transport generally for persons and goods. Adjustments to the thickness of the cushion and/or to the height at which it is placed, whether mounted inside or outside the seat back, ensure great benefits for the user since it supports the rib cage, facilitates digestion in persons wearing corsets, avoids or at least' lessens the effects of cervical arthritis.

- Fig.3 The cushion illustrated in Fig. l, from the back.
- Fig.4 Internal structure of the cushion in Figs.1 - 3.
- Fig.5 Motor vehicle seat with cushion for anatomical sup ⁇ port to the- lumbar-cervical regions mounted inside the seat back cut away to show the device.
- Figs.6-7 The seat in Fig.5 showing two positions for the internally mounted cushion.

- Fig.9 The cushion in Fig.8 seen from the back.
- Fig.10 Office armchair with cushion for anatomical support to the lumbar-cervical regions mounted inside the back.
- the cushion 10 (Figs. 1, 3, 4) is obtained from a device 11 comprising an elastic plate 12 with an upper end 13 and a lower end 14 curved back to form channels 15 and 16.
- These ends contain the pairs of slits 21 and 22 through which the bands 23 and 24 pass respectively, for holding said cushion 10 to the back 18 of the motort vehicle 17.
- the cushion 10 can of course be placed on the back seat at different heights by sliding it up or down the bands 5 23 and 24 .
- an aperture 20 (Fig. 3) is made to allow the fingers to work the scroll 36.
- Fig. 2 shows a cushion 25, substantially the same as the
- Figs. 5, 6 and 7 refer to a cushion 50 for supporting the lumbar-cervical regions, similar to cushions 10 and 25 al-
- Said rods comprise their flat ends 56 and 61 fixed respec ⁇ tively to the upper 52 and lower 53 channel-shaped ends of said plate 51, and the opposingly threaded ends 57 and 62 screwed into the cylindrical scroll 63.
- Said scroll is mechanically connected to the short shaft 65 by means of the bevel gear 66-67.
- Said bevel gear is held in place by the L-bar 68 whose ro ⁇ tation in relation to the gear wheel 66 is prevented by the rigid arm 69 with upper fork 70 into which is inserted the flat end 56 of the upper tie rod 55 mentioned above.
- the shaft 65 is mechanically connected to the revolving shaft 75 which turns on supports fixed to the back 42 of the seat 41 (not seen in Figure 5) by means of two univer ⁇ sal joints 76 and 78 at the ends of the intermediate shaft 77.
- the shaft 65 referred to above can be worked externally from the side 43 of the back 42 by means of the knob 44.
- Rotating said knob determines rotation of the scroll 63 and therefore increases or reduces, as preferred, convexity of the elastic plate 51 obtaining the same effects as given by manual rotation of the scroll 36 on plate 12 of device 11 illustrated previously in Figure 4.
- the plate 51 can slide on vertical guides 58, 59 made in ⁇ side the seat back 42, said guides passing through slits cut into said plate. Sliding movement is brought about by means of the contin- uous cord 71 fixed, at its two ends, to loops 54 placed top and bottom of said plate 51.
- the cord 71 passes over revolving transmission rollers 72 supported by the structure of the seat back 42 and winds round the drum 73 of the shaft 74 that terminates in the knob 45 projecting from the side 43 of said seat back.
- plate 51 can be moved up and down to the position preferred by the user. Said movement is made possible by universal joints 76 and 78 that give shaft 77 the angle necessary for moving the plate 51.
- Figs. 8 and 9 illustrate application of a cushion 85, si ⁇ milar to cushion 10 illustrated in Figs 1 - 4, to the back 84 of an office armchair 83 by means of Velcro-type strips 86, 87 that cling to the covering 88 of suitable composi ⁇ tion.
- FIG. 10 illustrates the applicat ion, inside the back 91 of an office chair 90,of a cushion 92 similar to cushion 50 already illustrated in Fig. 5.
- the plate 93 can be seen as well as the various mechanisms operated by means of knobs 94 and 95 for respectively vary ⁇ ing the convexity of said plate and for moving it vertical- ly on the seat back.
