Both the intermediate support and the back support are guided for movement relative to the base by a second guide means while the base moves along a first guide means. The first guide means include at least one guide associated with one of the base and intermediate support and at least one follower associated with the other of the base and intermediate support. The second guide means includes at least one guide associated with one of the base support and the back support and at least one follower associated with the other of the base support and the back support.

First claim

The invention claimed is:

1. An article of adjustable furniture, comprising:
a base, an intermediate support and a back support;
the intermediate support being guided for movement relative to the base by a first guide means;
the back support being mounted for rotational movement with respect to the intermediate support;
the first guide means including one or more pairs of guides connected with one of the base support and the intermediate support on each side of the article of adjustable furniture and one or more pairs followers connected with the other of the base support and the intermediate support; and
whereby the first guide means is arranged to provide relative linear upwards and forwards movement of the intermediate support with respect to the base when the back support is pivoted downwards from an upright position, wherein the base comprises a chassis on which the intermediate support is movable mounted, and the base support provides at least one part of a floor standing base support.

2. An article of furniture as claimed in claim 1 , wherein:
the first guide means includes at least one pair of guides associated with one of the base and intermediate support, and at least one pair of respective followers associated with the other of the base and intermediate support.

3. An article of furniture as claimed in claim 2 , wherein:
said at least one pair of guides includes a pair of fore and aft guides associated with one of the base and intermediate support on each side of the article of furniture, and a pair of respective fore and aft followers associated with the other of the base and intermediate support on each side of the article of furniture.

4. An article of furniture as claimed in claim 2 , wherein:
the at least one pair of guides includes at least one pair of guides inclined with respect to the base to guide the intermediate support in an upwards and forwards motion with respect to the base when the back support is pivoted downwards from an upright or partially reclined position.

5. An article of furniture as claimed in claim 2 , wherein:
the at least one pair of guides includes at least one pair of parallel guides inclined with respect to the base to guide the intermediate support in an upwards and forwards motion with respect to the base when the back support is pivoted downwards from an upright or partially reclined position.

6. An article of furniture as claimed in claim 1 , wherein:
the guides of the first guide means are associated with the base and the respective followers are associated with the intermediate support.

7. An article of furniture as claimed in claim 1 , wherein:
the guide comprises one of a slot, a groove, a track, in which said follower is located.

8. An article of furniture as claimed in claim 1 , wherein:
the follower comprises one of a roller and a bearing.

9. An article of furniture as claimed in claim 1 , further comprising:

10. An article of furniture as claimed in claim 1 , wherein:
the intermediate support includes a pair of lateral side panels, and wherein the side panels include the guides of the first guide means which guides accommodate the respective followers.

11. An article of furniture as claimed in claim 10 , wherein:
said guides are provided as respective slots in said side panels.

12. An article of furniture as claimed in claim 10 , wherein:
each panel includes a pair of slots which are inclined to guide the intermediate support upwards and forwards with respect to the base when the back support is pivoted downwards from an upright or partially reclined position.

13. An article of furniture as claimed in claim 12 , wherein:
said back support is pivotally connected to the respective lateral side panels.

14. An article of furniture as claimed in claim 1 , wherein:
the intermediate support further comprises:

18. An article of adjustable furniture, comprising:
a base, an intermediate support and a back support;
the intermediate support being guided for movement relative to the base by a first guide means;
the back support being mounted for rotational movement with respect to the intermediate support;
the first guide means including at least one guide connected with one of the base support and the intermediate support and at least one follower connected with the other of the base support and the intermediate support;
whereby the first guide means is arranged such that the intermediate support moves upwards and forwards with respect to the base when the back support is pivoted downwards from an upright position;
said first guide means is arranged to provide relative linear movement of the intermediate support with respect to the base;
the first guide means includes at least one pair of guides associated with one of the base and intermediate support on each side of the article of furniture, and at least one pair of respective followers associated with the other of the base and intermediate support on each side of the article of furniture;
the intermediate support includes a pair of lateral side panels, and wherein the side panels include the guides of the first guide means which guides accommodate the respective followers; and
