Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
A seat (10) adapted to accommodate three passengers comprising a seat cushion (11) and a seat back (12), three headrests (13, 14, 20) being located in juxtaposed relationship along an upper edge (15) of the seat back (12) and an armrest (25) being provided centrally of the seat back (12), the armrest (25) being selectively movable between a raised position in which it is flush with the seat back (12) and a lowered position in which it divides the seat (10) into two for occupation by two or fewer passengers, characterised in that the armrest (25) is interconnected to the central headrest (20) such that when the armrest (25) is in its lowered position, the central headrest (20) is retracted into the seat back (12), but when the armrest (25) is in its raised position the central headrest (20) will be raised so that it extends upwardly from the upper edge (15) of the seat back (12).
Claim 2
Dependent Claim
63 words
A seat (10) according to Claim 1 characterised in that the central headrest (20) is mounted upon a carriage (22), guide means (23) being provided to guide movement of the carriage (22) relative to the seat back (12) and links (30; 30') being provided between the carriage (22) and the armrest (25) to transmit movement of the armrest (25) to the carriage (22).
Claim 3
Dependent Claim
151 words
A seat (10) according to Claim 2 characterised in that the armrest (25) is pivotally connected to the seat back (12) so that the armrest (25) may be moved from its lowered position to its raised position by upward movement of the front edge of the armrest (25), the link (30) between the armrest (25) and carriage (22) being pivotally connected to the armrest (25) at a position (31) spaced forwardly of the pivotal connection (27, 28) to the seat back (12) when the armrest (25) is in its lowered position, so that as the armrest (25) is moved from its lowered position to its raised position, the pivotal connection (31) between the armrest (25) and the link (30) connected to the carriage (22) will move above the pivotal connection (27, 28) of the armrest (25) to the seat back (12), thereby raising the carriage (22) and headrest (20) attached thereto.
Claim 4
Dependent Claim
114 words
A seat (10) according to Claim 1 or 2 characterised in that the armrest (25) is pivotally connected to the seat back (12), so that it may be moved from its lowered position to its raised position by moving the rearward edge of the armrest upwardly, the pivotal connection (27) between the armrest (25) and seat (10) engaging in an elongate slot (40) so that the armrest (25) may be moved relative to the pivotal connection (27), and the pivotal connection (31') between the armrest (25) and the link (30') connecting the armrest (25) to the carriage (22) being positioned rearwardly of the pivotal connection (27) between the armrest (25) and seat back (12).
Claim 5
Dependent Claim
63 words
A seat (10) according to any one of Claims 1 to 4 characterised in that an upper mounting (35) for a seat belt (36) is interconnected with the armrest (25) so that the mounting (35) will move from a retracted position when the armrest (25) is in its lowered position to a raised position when the armrest (25) is in its raised position.
Claim 6
Dependent Claim
24 words
A seat (10) according to Claim 5 characterised in that the seat belt mounting (35) is arranged to move with the central headrest (20).
Claim 7
Dependent Claim
34 words
A seat (10) according to any one of the preceding claims characterised in that means is provided to prevent unintentional movement of the components (20, 25, 35) from either their raised or lowered position.
Claim 8
Dependent Claim
36 words
A seat (10) according to any one of the preceding claims characterised in that means is provided for preventing lowering of the components (20, 25, 35) when the central portion of the seat (10) is occupied.
Claim 9
Dependent Claim
33 words
A seat (10) according to any one of the preceding claims characterised in that means is provided to assist movement of the armrest (25) and headrest (20) between their raised and lowered positions.
Claim 10
Dependent Claim
35 words
A seat (10) according to any one of the preceding claims characterised in that means is provided for adjusting the height of the central headrest (20) when the armrest (25) is in its raised position.
