Description

<Desc/Clms Page number 1>
COMBINED SEAT AND BED ASSEMBLY The present invention relates to a combined seat and bed assembly, particularly, though not exclusively, to a seat convertible into a bed which may be employed in a caravan, whether motorised (e. g. a motorhome) or non- motorised.
It is known to provide seats which may be converted into beds. Such combined seat and bed assemblies are frequently employed in caravans where space is limited and allow the same section of the caravan to be used as both a living and sleeping area. Such combined seat and bed assemblies generally comprise a fixed base member and a back member moveable between a first seat position and a second bed position.
In one known assembly the back member is linked by an arm to a support structure which also supports the base member. To move the back member between its first and second position it must first be slid relative to the base member, then rotated about a pivot by which it is joined to the arm and then the arm and back member must both be rotated about a pivot by which the arm is joined to the support structure. Such an operation is undesirably complicated and time consuming. In a simpler assembly the back member comprises a loose cushion and the assembly comprises supports which may be housed within the base member and thus be put out of the way when the back member is in the seat position. To create a bed the supports must be manually positioned to support the back member and the back member must be lifted from its seat position and placed on the supports to define a bed. Again, this process is undesirably time consuming and is also fairly labour intensive.
The present invention aims to address at least one problem, whether described herein or otherwise, by providing a combined seat and bed assembly having a novel construction.

pass a position in which its front face is orientated towards the top face of the base member. Once past this point the weight of the back member may cause it to continue to rotate until its bottom edge abuts the top face of the base member.
According to the present invention there is further provided a vehicle or caravan comprising a combined seat and bed assembly as described by any statement herein.
The vehicle may comprise a caravan, motor home, train or a boat.
A specific embodiment of the present invention will now be described in detail with reference to the accompanying drawings in which: Figure 1 is a side elevation of a combined seat and bed assembly with the back member in a first position to define a seat; Figure 2 is a side elevation of a combined seat and bed assembly with the back member in a second position to define a bed; and Figures 3a to 3h are perspective views of a combined seat and bed assembly showing the movement of the back member between a first and second position.
As best illustrated by Figure 3a the combined seat and assembly 1 comprises a base member 10 and a back member 20. The back member 20 is moveable between a first position in which it defines a seat, best illustrated by Figure 1, and a second position in which it defines a bed, best illustrated by Figure 2.
When the back member 20 is in the first position it is arranged such that a front face 21 thereof lies substantially perpendicular to a top face 11 of the base
<Desc/Clms Page number 8>
member 10. In the first position the bottom edge 22 of the back member 20 abuts the top face 11 of the base member 10.
When the back member 20 is in the second position it is arranged such that the front face 21 thereof lies in substantially the same plane as the top face 11 of the base member 10. In the second position the top edge 23 of the back member 20 abuts the front edge 12 of the base member 10.
The back member 20 is linked to the base member 10 by a pair of first arms 30 and a pair of second arms 40. One of the first arms 30 is shown in Figures 1, 2 and 3a to 3h, as is one of the second arms 40. The other of each pair of arms is generally not shown but a part of each of the other first and second arms 30, 40 can be seen in Figure 3c, at the far side of the assembly.
As best illustrated by figures 1 and 2, each of the first arms 30 is secured to the base member about a pivot 31 and to the back member about a pivot 32.
Each of the second arms 40 is secured to the base member about pivot 41 and to the back member about pivot 42. Pivot 32 is arranged to lie closer to the top edge 23 of the back member 20 than its pivot 42. Pivot 31 is arranged to lie closer to the rear edge 15 of the base member than its pivot 41.
The pivots 31, 32, 41, 42 can comprise either bolts or screws.
Each of the first arms 30 comprises two substantially straight sections arranged to lie at an angle of approximately 1400 to one another and linked by a curved section.
Each of the second arms 40 comprises two substantially straight sections arranged to lie at an angle of approximately 1300 to one another and linked by a curved section.
<Desc/Clms Page number 9>
The second arms 40 are arranged to be secured to the base 10 and back members 20 inwards of the first arms 30 such that the first arms 30 can pass over the second arms 40 as the back member 20 is moved between its first and second positions.
The base 10 further comprises a stop 50 extending from either side 13,14 thereof and arranged to abut the first and second arms 30,40 when the back member is in the second position. The stop 50 acts to prevent the back member 20 passing its second position and can help support the weight exerted by a user on the back member in its second position.
The back member 20 comprises a stop 60 extending from either side 24,25 thereof and arranged to abut the second arms 40 when the back member is in the second position. The stop 60 acts to prevent the back member passing its second position. The stop 60 is arranged to extend from the back member such that the second arm can not pass over it but such that the first arm can move past it.
Both the base and back members comprise cushioned elements supported by support structures such that the front face 21 of the back member and the top face 11 of the base member are cushioned and their side edges 24,25, 13,14 respectively are rigid such that the arms 30,40 can be secured thereto.
Both the base and back members are covered with fabric such that neither the cushioned elements or support structures can be seen. The support structure of the base member further comprises legs 70 by which the base member is supported above floor level.
As best illustrated by figures 3a to 3h the back member is moved from its first position to its second position by drawing the top edge 23 of the back member towards the front edge 12 of the base member. The back member 20 rotates in a"tumbling"motion through approximately 2700 as it moves between its first
<Desc/Clms Page number 10>
and second positions. Once in its second position the back member 20 may be returned to the first position by first lifting and pushing the bottom edge 22 of the back member towards the rear edge 15 of the base member. Once again the back member rotates through approximately 2700 in a"tumbling" motion as it moves between its two positions.
