Abstract
Abstract The disclosure relates to a vehicle seat assembly (A) comprising a tubular frame means (10) for a seat (12) and backrest (14), a seat (12) and backrest (14) comprised of side by side elastomeric filaments (50) prestretched across side frames (20,22) and a backrest frame (30) and secured to the frame portions, and a cover means (16,18) to cover the seat (12) and backrest (14) whereby a thin seat is provided.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
171 words
A vehicle seat assembly (A) comprising tubular frame means(10) including laterally spaced, generally horizontal side frame portions (20,22) supporting a seat (12) formed from elastomeric means, and laterally spaced, generally vertically extending side frame portions (30) supporting a backrest (14), formed from elastomeric means, characterised in that said seat (12) and backrest (14) each comprise a multiplicity of individual, side by side located elastomeric filaments (50) of a diameter between 0.2 to 2.0 millimetres, and whose opposite ends are attached to said side frame portions (20,22,30) so that the filaments (50) extend perpendicular to said side frame portions (20,22,30) and said seat (12) and backrest (14) are of limited thickness, said elastomeric filaments (50) are made from a material having a substantially higher tensile strength than natural rubber and a modulus of elasticity at 100 percent elongation which is at least five times more than natural rubber, and said elastomeric filaments (50) are prestretched in the range between 20 and 100 percent elongation when attached to said side frame portions (20,22,30).
Claim 2
Dependent Claim
171 words
A vehicle seat assembly (A) comprising tubular frame means(10) including laterally spaced, generally horizontal side frame portions (20,22) supporting a seat (12) formed from elastomeric means, and laterally spaced, generally vertically extending side frame portions (30) supporting a backrest (14), formed from elastomeric means, characterised in that said seat (12) and backrest (14) each comprise a multiplicity of individual, side by side located elastomeric filaments (50) of a diameter between 0.2 to 2.0 millimetres, and whose opposite ends are attached to said side frame portions (20,22,30) so that the filaments (50) extend perpendicular to said side frame portions (20,22,30) and said seat (12) and backrest (14) are of limited thickness, said elastomeric filaments (50) are made from a material having a substantially higher tensile strength than natural rubber and a modulus of elasticity at 100 percent elongation which is at least five times more than natural rubber, and said elastomeric filaments (50) are prestretched in the range between 20 and 100 percent elongation when attached to said side frame portions (20,22,30).
Claim 3
Dependent Claim
37 words
A vehicle seat assembly according to claim 1, characterised in that each elastomeric filament (50) has an approximate diameter of 0.5 millimetres and is made from a block copolymer consisting of polytetramethylene terephthalate polyester and poly(tetramethylene ether).
Claim 4
Dependent Claim
46 words
A vehicle seat assembly according to claim 2, characterised in that there are about six elastomeric filaments (50) per centimetre of side frame (20,22) in said seat (12) and there are about three elastomeric filaments (50) per centimetre of side frame (30) in said backrest (14).
Claim 5
Dependent Claim
31 words
A vehicle seat assembly according to any one of the preceding claims, characterised in that the seat assembly (B) includes means (78) for adjusting the tension of the elastomeric filaments (50).
