(cl. 5-43) tion in which it provides a rsupport for a mattress or the like to 4,constitute a bedel' bunk. 4
Itis lan object of the invention to provide ,an improved ,seat of the kind described is particularly ,suitable for use where spacelisrer stricted, e. g. in ships, tra-ins, motor coaches and other vehicles.
The inyention provides inpne aspect aseat,
Settee Orthelke, of the sind desqrfibed, 9h the back portion is supported for pivotal movement about a substantially horizontal axis above the level of the seat portion, so that it may be rotated from its upstanding position to a substantially horizontal position in which it lies partly above the seat portion lwith its rear face directed upwardly, and in which means are pr vided for moving the back portion and its pivotal axis over the seat portion during the aforesaid rotational movement.
This arrangement has, among others, the advantage that the back portion, when in the upright position, may extend downwardly behind the rear of the seat portion, and that during the movement of the back portion to the horizontal or bed position, the lower edge of the back portion may be constrained to follow a substantially vertical path, or preferably, an upward path with a rearwards component so that when in the bed position the edge is located within a recess provided behind the back portion, which recess is for the purpose of accommodating the thickness of the back portion, or a mattress thereon, when in the upright position.
The aforesaid pivotal axis is preferably itself movable by a swinging movement about a parallel axis above it.
In the preferred form of the invention, the back portion is suspended from a support by links movable in substantially vertical planes and pivoted at their upper ends to the support near the top of the back portion and pivoted at their lower ends to the back portion at a position intermediate in the height of the back portion between the upper pivots and the top of the seat portion, the upper and lower pivotal axes extending horizontally and lengthwise of the back portion and the lower edge of the back portion has means icio-operating with a cam surface provided on the support to move the back portion forward over the seat portion with corresponding swinging movei2 mentor tu@ `as the pack vportion is rotated, ahelltieelc @reads "1f.thelieke-k Vspecific constru nfof a seat convertible intoV a lbed land rem kying the invention will .new 39s' essribedl y -wavgf exemple and with refer l @ne ,aa-ennemies drawings. .in

In this example, the seat comprises a seat portion I and a back portion 2. The seat portion I is supported on horizontal bearers 3 and comprises a sprung upholstered unit having a seat base 4 of spring units, an intermediate layer 5 comprising a large number of small helical springs each contained in a separate fabric or other flexible pocket, and an upper layer 6 of upholstery comprising, for example, felt, or curled hair.
The back portion 2 comprises a frame 'I sup-- porting a spring unit 8 having on one side thereof a spring upholstered backrest unit comprising spring units 9. On the other side (i. e. the rear face) of the spring unit 8 the back portion 2 comprises a pocketed spring mattress I I. The spring unit 8 serves as a resilient support for the mattress and also for the back rest unit.. The mattress I I is |located in position on the back portion by channel members I2 and facing boards I 3 and I4, and is held, with the bed-clothes, by two straps I 9 when the back portion is in the upright position.
The back portion 2 is suspended from a vertical support I5 by links I6 at each end of the back pivoted at their lower ends toI the back portion at Il and pivoted at their upper ends to the support I5 at I8. The back portion 2 carries at each end a rotatable roller 2| which runs along cam surfaces 22 as the back portion 2 is rotated about the pivots Il. The surface I9 of the back portion is convexly arcuate about the axis of the pivots I'I.
When the back portion is rotated about the pivots I 'I from its upstancling position (Figure 3). the rollers 2l run up thei'cam faces 22 and move the back portion 2 forward over the seat portion I, the links I 6 simultaneously rotating about the pivots I8 to permit the forward movement of the back portion. When the back portion has reached its horizontal position (as shown in Figure 2) the rollers 2| are received within channels or notches 23 by a slight backward movement of the back portion, thereby retaining the back portion in the horizontal position so that a person may recline on the mattress Il. When in this position the surface of the back rest unit contacts the seat portion.
When the back portion 2 is in the settee position shown in Figure 3 a spring balldetent 25 engages in a recess on the pivot pin I8 to retain the portion in position.
The invention is not restricted to the details of the foregoing example. For instance, another unit, similar to the back portion 2 but without the seat may be provided vertically above the back portion 2 so that a two-tier bunk is thereby provided.
I claim:
A bed convertible to a seat and comprising a support frame, an elongated seat portion supported in fixed relation by the frame, a horizontal bed portion overlying the seat portion, substantially in contact with the upper surface thereof and extending to the rear thereof, the length of the bed extending lengthwise of the seat portion, links movable in a vertical plane supporting the bed portion in hanging relation from the frame and pivoted at their upper ends to the frame at a position above the bed portion and pivoted at their lower ends te the bed portion at a position which overlies the seat portion, is spaced from the upper surface thereof and is further from the rear edge `of the bed portion than it is from the surface of the seat portion, the under surface of the bed portion towards the rear edge from the pivot axis being convexly arcuate about the pivot axis, a cam surface secured to the frame and extending downwardly from a position adjacent the rear edge of the bed portion and forwardly near its lower end, the cam surface having a rearwardly extending notch at its upper end, and a cam follower on the rear edge of the bed portion engaged within the notch, the bed portion being movable from the horizontal position aforesaid by disengagement of the follower from the notch and by pivotal movement about the attachment to the lower ends of the links with rolling movement of the aforesaid arcuate surface over the seat and by cooperation of the follower with the cam surface accompanied by swinging movement of the links, into a position in which the bed portion has its width extending upwardly and constitutes a back for the seat, the lower edge of the bed portion extending below and behind the seat portion.
