Abstract

A first object of the invention is an aircraft seat element comprising:

a rigid frame (1) having two substantially parallel lateral rods (2, 3) immovably attached rigidly at one of their ends (2a, 3a) to a cross-member (4), the other end (2b, 3b) of said rods being fixed in an articulated manner to a shaft (5), said shaft (5) being removable;

a tubular cloth (6) slipped over said frame (1) and forming the back piece of said seat element.

This seat element is characterized in that the cloth (6) used is an elastic cloth, the fibers of which have different stiffnesses depending on their direction.

Another object of the invention is the method for mounting said seat element.

Claims

1. An aircraft seat element, comprising:

a rigid frame (1) having two substantially parallel lateral rods (2, 3) immovably attached rigidly at one of their ends (2a, 3a) to a cross-member (4), the other end (2b, 3b) of said rods being fixed in an articulated manner to a shaft (5), said shaft (5) being removable;

a tubular cloth (6) slipped over said frame (1) and forming the back piece of said seat element,

characterised in that the cloth (6) used is an elastic cloth, the fibres of which have different stiffnesses depending on their direction.

3. A seat element according to either of claims 1 or 2, characterised in that the cloth (6) comprises two pieces of cloth (6a, 6b) of substantially rectangular shape assembled by their lateral edges so as to take the shape of said element.

4. A seat element according to claim 3, characterised in that the two pieces of cloth (6a, 6b) are assembled by sewing.

5. A seat element according to either of claims 1 or 2, characterised in that the cloth (6) comprises a single substantially rectangular piece, the lateral edges of which are assembled by assembling means (13).

6. A seat element according to one of claims 1 to 5, characterised in that the tubular cloth (6) has, on its lower part (7), means of attachment (8) to the articulation shaft (5) of said element so that said tubular cloth (6) is stretched vertically on said frame (1).

7. A seat element according to one of claims 1 to 6, characterised in that the articulation shaft (5) is fixed by screws and bolts onto the lower ends (2b, 3b) of the rods of said frame (1).

8. A seat element according to one of claims 1 to 7, characterised in that it comprises a foam-lined protective cover (11) slipped over said tubular cloth (6).

9. A seat element according to claim 8, characterised in that said protective cover (11) comprises closure means (12).

10. A seat element according to one of claims 1 to 9, characterised in that said seat element forms the structure of the seat back or of the seat base of the seat.

11. A method for mounting the seat element according to one of claims 1 to 4 and 6 to 10 when they depend on claim 3, characterised in that it comprises the steps consisting in:

slipping the tubular cloth (6) over the rods (2, 3) of the frame (1) by way of the ends (2a, 2b) of the rods opposite the cross-member, the articulation shaft (5) of said element being removed, so that the ends opposite the cross-member (2b, 3b) of said rods are narrowed to facilitate the passage of the tubular cloth (6);

fixing the articulation shaft (5) of said element onto the ends opposite the cross-member (2b, 3b) of the rods in order to move the latter apart and stretch the tubular cloth (6) laterally;

fixing the tubular cloth (6) onto the articulation shaft (5) by means of attaching (8) said cloth in order to stretch the cloth vertically.

12. A method for mounting the seat element according to one of claims 1 to 2, 5 and 6 to 10 when they depend on claim 5, characterised in that it comprises the steps consisting in:

placing the cloth on the frame 1 and assembling the lateral edges of the cloth by the assembling means (13);

fixing the tubular cloth (6) onto the articulation shaft (5) by means of attaching (8) said cloth in order to stretch the cloth vertically.

13. A mounting method according to claims 12 or 13, characterised in that it also comprises the steps consisting in:

slipping a foam-lined protective cover (11) over the seat element frame (1) by way of the end thereof on the same side as the cross-member, the tubular cloth (6) being in place;

closing said protective cover (11) by said protective cover closure means (12).

2. A seat element according to claim l, characterised in that the cloth (6) is a unidirectional elastic cloth disposed so that the direction of the elastic fibres of said cloth is perpendicular to the lateral rods (2, 3) of said seat element.
