An anti-crash seat (1) for a vehicle, the seat comprising a bucket (2) and a frame (6), said bucket (2) being provided with a seat proper (3) and with a back (4) for receiving a person. Said seat (1) includes crash energy absorber means (10) and antivibration means (20). The seat also includes inhibitor means (30) for inhibiting said antivibration means (20) so as to neutralize the antivibration means (20) when the seat (1) is subjected to acceleration towards the floor that is greater than a predetermined threshold.
An anti-crash seat for a vehicle, the seat comprising a bucket and a frame fastened to a floor for carrying said bucket, said bucket being provided with a seat bottom and with a back for receiving a person, said seat including crash energy absorber means and antivibration means, wherein the seat includes inhibitor means for inhibiting said antivibration means to neutralize the antivibration means when the bucket is subjected to acceleration towards the floor that is greater than a predetermined threshold, wherein said crash energy absorber means include a first end fastened to the bucket and a second end movable relative to said frame, said inhibitor means being linked to said second end by link means to block said second end when the bucket is subjected to acceleration towards the floor that is greater than said predetermined threshold.

This application claims the benefit of FR 10 00718 filed on Feb. 23, 2010. The disclosure of which is incorporated in its entirety by reference herein.
(1) Field of the Invention
The present invention relates in particular to the field of powered aircraft, in particular airplanes and rotorcraft, and more particularly to the field of accessories for fitting to such aircraft. The invention provides an anti-crash seat for a vehicle, and in particular for powered aircraft. The seat includes means for protecting a passenger in the event of a violent impact and/or of a sudden change in the speed of the aircraft, in particular during a crash.
The invention and its advantages appear in greater detail in the context of the following description with embodiments given by way of illustration and with reference to the accompanying figures, in which:
FIG. 1 is a view explaining the operation of the invention;
FIG. 2 is a side view showing inhibitor means;
Elements that are present in more than one of the figures are given the same references in each of them.
FIG. 1 shows an anti-crash seat 1 for a vehicle, and more particularly a seat for an aircraft of the rotorcraft type, for example.
The seat 1 comprises a bucket 2 suspended from a frame 6 standing on the floor 9 of the aircraft. The bucket 2 comprises a seat proper 3 situated substantially in a first plane X, Y and a back 4 situated substantially in a second plane Y, Z. It should be observed that the three axes X, Y, Z defining the first and second planes may correspond to the reference axes of the aircraft or they may present angles relative to said reference axes, the first reference axis corresponding to the roll axis of the aircraft, the second reference axis corresponding to the pitching axis of the aircraft, and the third reference axis corresponding to the yaw axis of the aircraft.
