Abstract

The invention relates to an aircraft safety seat (1) comprising a supporting structure (5) and a bucket seat (2) supported by said structure, said bucket seat (2) comprising a seat (3) and a back (4) which are linked together, said back being installed on said structure so as to slide generally downwards, characterised in that it comprises at least one connecting rod (6) connected by its first end (6a) to said support and by its other end (6b) to said seat, said connecting rod (6) being generally horizontal when in normal use, and being suited for pivoting downwards by its first end under the effect of a force exerted downwards on said seat, against the action of a shock absorber (7).

Claims

1. An aircraft safety seat comprising a supporting structure and a bucket seat supported by said supporting structure, said bucket seat comprising a seat and a back linked together, said back being installed on said supporting structure so as to slide generally downwards, wherein at least one connecting rod connected at a first end to said supporting structure and at a second end to said seat, said connecting rod being generally horizontal when in normal use, and being suited for pivoting downwards by its first end under the effect of a force exerted downwards on said seat, against the action of a traction shock absorber.

2. An aircraft safety seat according to claim 1, in which said shock absorber is a linear absorber in which a first end is fixed to said supporting structure and a second end is fixed to said connecting rod.

3. An aircraft seat according to claim 2, in which said first end of the linear absorber is fixed to said supporting structure above the connection point of said connecting rod.

4. An aircraft safety seat according to claim 1, in which said back is installed so as to slide on said supporting structure by at least one annular linear element.

5. An aircraft safety seat according to claim 1, in which said supporting structure comprises a fixed part and a mobile part, said mobile part being installed in an adjustable fashion so as to slide generally vertically on said fixed part, and said connecting rod being connected by its first end to said mobile part.

6. An aircraft safety seat according to claim 1, in which said bucket seat and said mobile part are assembled so as to slide on said fixed part in substantially the same direction.

7. An aircraft safety seat according to claim 1, comprising two lateral connecting rods, each of which is connected to one of the sides of said seat.

8. An aircraft safety seat according to claim 7, comprising an attachment point for a seatbelt on the connection between at least one of said lateral connecting rods and the supporting structure.

9. An aircraft safety seat according to claim 7, comprising an attachment point for a seatbelt on said bucket seat, said attachment point being connected by another connecting rod to the connection between the supporting structure and at least one of said lateral connecting rods, said other connecting rod being designed to deform in the event of a crash.

10. An aircraft safety seat according to claim 8, further comprising a lap, sash or crotch-strap seatbelt.

11. An aircraft safety seat according to claim 1, wherein the assembly consisting of the support structure, the bucket seat and the shock absorber is prestressed during assembly.

12. An aircraft safety seat according to claim 11, in which the prestressing is obtained by means of screw-nut interferences on at least one of the ends of the shock absorber.
